This disclosure relates to liquid treatment compositions comprising granular and adjuvant components, wherein the granules comprise plant rosin material and one or more beneficial agents. This disclosure also relates to methods for preparing and using such compositions.

Description

Technical Field

[0001] This disclosure relates to liquid treatment compositions comprising granular and adjuvant components, wherein the granules comprise plant rosin material and one or more beneficial agents. This disclosure also relates to methods for preparing and using such compositions. Background Technology

[0002] Various delivery systems can be employed to facilitate the improved delivery of beneficial agents in processing compositions such as liquid fabric softeners. Granules are often chosen as the delivery system, particularly for fragrances.

[0003] For example, fragrances can be encapsulated in core-shell particles to achieve better fragrance deposition and refreshing benefits across multiple contact points. Other materials, such as amphiphilic graft copolymers, have been disclosed as capable of associating with beneficial agents to form particles that can then be deposited onto surfaces such as fabrics.

[0004] However, a drawback of these delivery systems is that they often require synthetic materials, such as synthetic polymers, while manufacturers, suppliers, and consumers increasingly prefer materials derived from natural and / or sustainable sources.

[0005] Additionally or alternatively, some of the materials used to encapsulate or embed the beneficial agent are easily diluted, causing the beneficial agent to be released during aqueous treatment cycles. Because the release occurs before deposition on the target surface, the performance of the beneficial agent is diminished at certain points of contact (such as on dry fabrics).

[0006] There is a persistent need for treatment compositions that provide improved delivery mechanisms for beneficial agents derived from natural sources. Summary of the Invention

[0007] This disclosure relates to a liquid treatment composition comprising granules and adjuvant ingredients, wherein the granules comprise plant rosin material and one or more beneficial agents.

[0008] This disclosure also relates to a liquid treatment composition comprising granules and adjuvant components, wherein the granules comprise tricyclic diterpenoid monocarboxylic acids, their derivatives, or mixtures thereof, wherein the granules further comprise one or more beneficial agents, preferably wherein the tricyclic diterpenoid monocarboxylic acids, their derivatives, or mixtures thereof comprise materials selected from: abietic acid type acids, their derivatives, pinoic acid type acids, their derivatives, and mixtures thereof, more preferably wherein the tricyclic diterpenoid monocarboxylic acid comprises derivatives in ester form.

[0009] This disclosure also relates to a method for treating a surface (preferably a fabric), wherein the method includes the step of contacting the surface with a liquid treatment composition as described herein, optionally in the presence of water. Attached Figure Description

[0019] This disclosure relates to liquid processing compositions comprising beneficial agent delivery particles (or simply "particles," as used herein). The particles of this disclosure comprise plant-based rosin materials and one or more beneficial agents, such as fragrances. As indicated in the name, plant-based rosin materials are derived from plants, typically from pine trees, and are therefore attractive as natural or sustainable materials, even if subsequently modified or derivatized.

[0020] Surprisingly, particles containing the plant-based rosin materials and beneficial agents disclosed herein have been found to function as an effective delivery system in liquid treatment compositions. These rosins are typically characterized, for example, by high levels of abietic acid. Without being bound by theory, it is believed that the structure of abietic acid-type materials leads to interactions with the fragrance raw materials arising from hydrophobic regions. This can result in the formation of relatively stable, relatively large particles. It is believed that the particles can withstand water dilution; for example, in the case of fabric care products, they tolerate the dilution step during a washing cycle, thus maintaining associations conducive to the deposition of beneficial agents. Furthermore, it is believed that the rosin materials are characterized by a relatively high molecular weight, which, compared to other smaller compounds, makes them more likely to deposit on target surfaces such as fabrics.

[0021] The components, compositions, and methods disclosed herein will be described in more detail below.

[0022] As used herein, the articles “a” and “an” when used in a claim are to be understood to refer to one or more things protected or described by the claims. As used herein, the terms “comprising,” “including,” and “containing” are intended to be non-limiting. The compositions of this disclosure may comprise, consist substantially of, or be composed of the components of this disclosure.

[0023] This document may use the term "substantially free of" (or "substantially free from"). This means that the referred material is present in very small amounts, not intentionally added to the composition to form a portion of the composition, or preferably not at analytically detectable levels. It also means that the referred material is present in a composition only as an impurity among other intentionally added materials. If present, the referred material may be present at levels of less than 1%, less than 0.1%, less than 0.01%, or even 0% by weight of the composition.

[0024] As used herein, the phrase "fabric care composition" includes compositions and formulations designed to treat fabrics. Such compositions include, but are not limited to, laundry cleaning compositions and detergents, fabric softening compositions, fabric strengthening compositions, fabric freshening compositions, laundry pre-wash agents, laundry pretreatment agents, laundry additives, spray products, dry cleaning agents or compositions, laundry rinsing additives, washing additives, post-rinse fabric treatment agents, ironing aids, unit-dosage formulations, delayed-delivery formulations, detergents on or incorporated into porous substrates or nonwoven sheets, and other suitable forms that are apparent to those skilled in the art based on the teachings herein. Such compositions can be used as laundry pretreatment agents, laundry posttreatment agents, or can be added during rinsing or washing cycles of a laundry operation.

[0025] Unless otherwise specified, all component or composition levels refer to the active portion of the component or composition and do not include impurities, such as residual solvents or byproducts, that may be present in commercially available sources of such components or compositions.

[0026] Unless otherwise specified, all temperatures in this document are in degrees Celsius (°C). Unless otherwise specified, all measurements in this document were taken at 20°C and atmospheric pressure.

[0027] In all embodiments of this disclosure, unless otherwise specified, all percentages are by weight of the total composition. Unless otherwise specified, all ratios are by weight.

[0028] It should be understood that each maximum numerical limit given in this specification includes each lower numerical limit, as such lower numerical limits are explicitly stated herein. Each minimum numerical limit given in this specification will include each higher numerical limit, as such higher numerical limits are explicitly stated herein. Each numerical range given in this specification will include each narrower numerical range falling within such a wider numerical range, as all such narrower numerical ranges are explicitly stated herein.

[0029] Treatment composition

[0030] This disclosure relates to liquid treatment compositions comprising particulate and additive components.

[0031] The treatment composition can be a consumer product composition. The consumer product composition can be a fabric care composition, a hard surface cleaner composition, a dishwashing composition, a hair care composition, a body cleansing composition, or a mixture thereof. The consumer product composition can be a conditioning composition, such as a liquid fabric strengthener composition or a hair conditioner composition.

[0032] The treatment compositions disclosed herein may be fabric care compositions. Such compositions may be used as pre-treatment agents for laundry, post-treatment agents for laundry, or may be added during the rinsing or washing cycles of a laundry operation. Fabric care compositions may be fabric detergent compositions, fabric conditioning compositions, or mixtures thereof, preferably fabric conditioning compositions. Fabric conditioning compositions may include liquid fabric softeners and liquid fabric strengthening compositions.

[0033] The treatment composition may be encapsulated in a water-soluble film to have the form of a combined unit dose article (such as a sachet). The water-soluble film may be a polyvinyl alcohol water-soluble film. Suitable films are available from MonoSol, LLC (Indiana, USA). The treatment composition may be encapsulated in a single-compartment sachet or a multi-compartment sachet. The multi-compartment sachet may have at least two, at least three, or at least four compartments. The multi-compartment sachet may include compartments arranged side-by-side and / or stacked. The composition contained in the sachet or its compartments may be a liquid, a solid (such as a powder), or a combination thereof; in such cases, at least one encapsulated composition is a liquid composition. Unit dose articles such as sachets and water-soluble films will be described in more detail below.

[0034] The composition is characterized by its viscosity. The disclosed composition has a viscosity of 20s. -1 At 21°C, it can have viscosities of about 1 centipoise to about 1500 centipoise (about 1 mPa*s to 1500 mPa*s), about 50 centipoise to about 1000 centipoise (about 50 mPa*s to 1000 mPa*s), or about 100 centipoise to 500 centipoise (about 100 mPa*s to 500 mPa*s), or about 100 centipoise to about 200 centipoise (about 100 mPa*s to 200 mPa*s). Relatively low viscosity allows for improved dosing and / or reduced residue in the dispenser drawer. Viscosity was determined according to the methods provided in the “Test Methods” section below.

[0035] The treatment compositions of this disclosure are characterized by a pH of about 2 to about 12, or about 2 to about 8.5, or about 2 to about 7, or about 2 to about 5. The treatment compositions of this disclosure may have a pH of about 2 to about 4, preferably about 2 to about 3.7, more preferably about 2 to about 3.5, and are preferably in the form of an aqueous liquid. Such pH levels are believed to be beneficial to the stability of certain adjuvants such as conditioning actives (e.g., ester-based quaternary ammonium salts). The pH of the composition is determined by dissolving / dispersing the composition in deionized water at about 20°C to form a 10% concentration solution.

[0036] Delivering particles (or "particles")

[0037] This disclosure relates to the delivery of particles, also referred to herein as "particles". The particles contain plant-based rosin material and one or more beneficial agents.

[0038] The one or more beneficial agents may be encapsulated in and / or embedded in plant rosin materials. The compositions disclosed herein may comprise the particles described herein.

[0039] The particles disclosed herein may exist in a population having a volume-weighted average diameter (or “diameter” as used herein). The volume-weighted average diameter is determined according to the methods provided in the “Test Methods” section below. The particles may have a volume-weighted average diameter of about 10 micrometers to about 400 micrometers. Without being bound by theory, it is believed that smaller particles will be less effective than delivery particles, and larger particles may be visible in the final product and / or cause undesirable spots on the target surface. Particles at the lower limit of this range may be preferred to improve the efficiency of fragrance delivery, as larger particles tend to have a relatively high ratio of rosin material to fragrance. The particles may be characterized by a volume-weighted median particle size of about 10 micrometers to about 400 micrometers, or about 15 micrometers to about 300 micrometers, or about 20 micrometers to about 250 micrometers, or about 25 micrometers to about 200 micrometers, or about 30 micrometers to about 150 micrometers, or about 35 micrometers to about 125 micrometers, preferably about 40 micrometers to about 100 micrometers, more preferably about 50 micrometers to about 90 micrometers.

[0040] One or more particles disclosed herein may have at least one region containing a beneficial agent, such as a flavoring agent or an enzyme. The region may contain a beneficial agent, such as a flavoring agent or an enzyme, which is contained or encapsulated within a plant-based rosin material. The region may contain a beneficial agent, such as a flavoring agent or an enzyme, which is embedded (e.g., partially embedded) within a plant-based rosin material.

[0041] One or more particles disclosed herein may have a structure selected from the group consisting of: (a) particles having a single region having a beneficial agent embedded in a plant rosin material; (b) particles having at least two regions having a beneficial agent embedded in a plant rosin material; (c) particles having at least one region having a beneficial agent at least partially embedded on the surface of a plant rosin material; (d) particles having a single region and at least one region having a beneficial agent embedded in a plant rosin material, and the at least one region having a beneficial agent at least partially embedded on the surface of a plant rosin material; and (e) particles having at least two regions and at least one region having a beneficial agent embedded in a plant rosin material, and the at least one region having a beneficial agent at least partially embedded on the surface of a plant rosin material. The compositions disclosed herein may comprise one or more particles or mixtures thereof having the structures according to (a) to (e).

[0042] The granules are characterized by the weight ratio of plant rosin material to a beneficial agent (e.g., preferably a fragrance). The plant rosin material and one or more beneficial agents may be present in the granules in a weight ratio of about 5:95 to about 95:5, preferably about 20:80 to about 80:20, more preferably about 30:70 to about 70:30, and even more preferably about 40:60 to about 60:40. This weight ratio may be about 50:50 to about 80:20, or about 50:50 or about 70:30. A rosin material:beneficial agent weight ratio close to 50:50 may be preferred to provide a relatively good balance between performance and ease of processing; a ratio relatively higher than 50:50 may provide improved performance, provided that the beneficial agent is added / present at a consistent level.

[0043] The treatment composition disclosed herein may comprise from about 0.01% to about 10%, or about 0.05% to about 7%, or about 0.1% to about 5%, more preferably 0.8% to 4%, or about 1% to about 3% of rosin-based particles by weight of the treatment composition. Such particles may comprise rosin material and beneficial agents (preferably fragrance ingredients) in a weight ratio of 70:30 to 50:50.

[0044] The plant-based rosin material and beneficial agents in this granule will be described in more detail below.

[0045] a. Plant-based rosin materials

[0046] The compositions, granules, and methods described herein comprise plant-based rosin materials. As used herein, "plant-based rosin material" may include plant-based rosins (including resin acids), plant-based rosin derivatives, or mixtures thereof. The plant-based rosin materials in the compositions, granules, and methods of the present invention can provide beneficial performance effects, such as by promoting improved deposition and / or stability of beneficial agents. In the compositions and methods disclosed herein, such materials may be further preferred over known alternatives because they are derived from natural and / or sustainable resources.

[0047] As discussed in more detail below, plant rosin is generally derived from conifers (class: Pinopsida), typically from pine trees (genus: Pinus). Plant rosin, also known as "rosin," is a solid material produced by heating liquid resin to evaporate volatile liquid terpene components. Plant rosin typically consists of resin acids such as abietic acid and related compounds. Plant rosin can be further derivatized, for example, through esterification and / or hydrogenation.

[0048] The compositions disclosed herein may further comprise from about 0.01% to about 10% by weight of the composition of plant-based rosin material. The compositions may comprise from about 0.01% to about 5%, or about 0.05% to about 3%, or about 0.1% to about 1% by weight of the composition of plant-based rosin material.

[0049] Plant-based rosin materials are characterized by their softening point. While plant-based rosin materials are typically solid at room temperature, their softening point is a measure of the glass transition temperature associated with these materials. The softening point of plant-based rosin materials is determined according to the methods provided in the "Test Methods" section below.

[0050] The plant-based rosin materials are characterized by a softening point of about 50°C to about 175°C, or about 60°C to about 150°C, or about 75°C to about 125°C. Rosin may require softening by heating for incorporation into consumer products. Therefore, plant-based rosin materials with relatively low softening points (e.g., less than 125°C) are preferred for ease of processing and / or energy saving in the compositions and methods disclosed herein. A lower softening point can also improve the deposition aid properties of the plant-based rosin materials.

[0051] Plant-based rosin materials are characterized by their acid number (sometimes called "acid value"). The acid value of plant-based rosin materials is related to the total free acid content of these products. The acid value of plant-based rosin materials is determined according to the methods provided in the "Test Methods" section below.

[0052] The plant-based rosin material is characterized by an acid value of less than about 175, for example, from about 0 to about 175. For the particles, compositions, and methods of this disclosure, plant-based rosin materials with relatively low acid values ​​(such as less than about 125, preferably less than about 100, more preferably less than about 75, even more preferably less than about 50, more preferably less than about 25) are preferably used to minimize the impact on the final pH of the treated composition. Without being theoretically constrained, it is believed that plant-based rosin materials with relatively low acid values ​​can also be more easily dispersed in the treated compositions of this disclosure.

[0053] The color of the plant-based rosin material can be graded based on the Gardner color standard numbering, ranging from 1 to 18. To minimize the impact on the final color of the treated composition, the preferred plant-based rosin materials of this disclosure may have a color grade of about 1 to about 10, preferably about 1 to about 8. The color grade of the plant-based rosin material is determined according to the methods provided in the “Test Methods” section below.

[0054] Plant-based rosin materials may have an odor. Naturally derived resins contain a large number of terpenoid compounds. For the compositions and methods of this disclosure, compounds having a relatively small amount of terpenoid structure and / or odor are preferably selected, such that the natural derived resin will not interfere with the overall characteristic perception. On the other hand, the presence of terpenoid structures may be preferred if a pine-like aroma characteristic is desired.

[0055] For example, resin rosin may be preferred over tall oil rosin because tall oil rosin may contain sulfur contaminants that affect odor. On the other hand, plant-based rosin materials may be expected to have a detectable odor because a "pine-like" odor associated with the rosin material may be useful or desirable in a particular product composition.

[0056] Plant-based rosin materials are generally relatively insoluble in water. For example, the plant resin materials according to this disclosure are characterized by a solubility of less than 1 g / L, or less than 100 g / L, or less than 1 g / L, or less than 0.1 g / L, or less than about 0.01 g / L in deionized water at 22°C. Without being bound by theory, it is believed that the relatively insoluble nature of the plant-based rosin materials of this disclosure contributes to the deposition efficiency and performance of associated beneficial agents. For example, it is believed that when the treatment composition is diluted during a treatment process (such as a washing or rinsing cycle in an automatic washing machine), the rosin-based particles of this disclosure are less likely to dissolve or decompose compared to particles containing a PEG / vinyl acetate graft copolymer, thereby improving deposition and performance.

[0057] The characteristic of plant-based rosin materials lies in their density. Typically, plant-based rosin materials are characterized by a density greater than 1.0 kg / dm³ at 25°C. 3 Preferably at least 1.1 kg / dm 3 The density.

[0058] Plant-based rosin materials are generally flammable. For the particles, compositions, and methods of this disclosure, plant-based rosin materials with relatively high flash points (e.g., above 190°C) are preferred to facilitate easier and safer processing. The flash point of the plant-based rosin material is determined according to the methods provided in the "Test Methods" section below.

[0059] The processing composition disclosed herein may comprise particles containing a plant-based rosin material, wherein the plant-based rosin material may comprise materials selected from the group consisting of: resin rosin, wood rosin, tall oil rosin, derivatives thereof, and mixtures thereof; preferably resin rosin, derivatives thereof, and mixtures thereof; more preferably terpinene rosin ester. The plant-based rosin material may be a plant-based rosin ester, preferably an ester formed from an alcohol having two or more carbon atoms, more preferably, wherein the alcohol is glycerol, pentaerythritol, or mixtures thereof. The plant-based rosin material may be at least partially hydrogenated, preferably fully hydrogenated. The plant-based rosin material may comprise at least 50%, more preferably at least 60%, more preferably at least 70%, more preferably at least 80%, more preferably at least 85% by weight of abietic acid, derivatives of abietic acid, or mixtures thereof.

[0060] Plant-based rosin and its derivatives, as well as premixes containing such substances, will be discussed in more detail below.

[0061] 1. Plant-based rosin

[0062] The plant-based rosin materials disclosed herein may include plant-based rosin. Plant-based rosin is typically obtained from the oleoresin of plants, which may be exuded from pine trees or otherwise derived. The oleoresin may be distilled to remove volatile terpenes, and the solid material remaining is plant-based rosin.

[0063] Plant-based rosin can be solid at room temperature. Solid rosin can be relatively translucent and / or glassy. Plant-based rosin materials can have a color range, for example, from pale yellow to dark brown or even black.

[0064] Plant-based rosin is typically a mixture of compounds and primarily consists of resin acids (also known as rosin acids). Plant-based rosin may contain at least about 75%, or at least about 80%, or at least about 85%, or at least about 90%, or at least about 95% of resin acids by weight of the plant-based rosin. Plant-based rosin may contain about 75% to about 97%, or about 80% to about 96%, or about 85% to about 95%, or about 90% to about 95% of resin acids by weight of the plant-based rosin. The remaining material may be non-acidic material.

[0065] Resin acids are typically monocarboxylic acids with three fused rings. Resin acids can also be tricyclic diterpenoid monocarboxylic acids, for example, those with the molecular formula C1. 19 H 29 COOH. Resin acids may include abietic acids, pinoic acid acids, thuja acid, or mixtures thereof. The double bonds in abietic acids are usually conjugated, while the double bonds in pinoic acid acids are usually not conjugated.

[0066] Abietic acids may include abietic acid, neoabietic acid, dehydroabietic acid, longleaf abietic acid, L-piperidine, or mixtures thereof. Piperidine acids may include piratic acid, isopiratic acid, santalinic acid, or mixtures thereof. The structures of these exemplary resin acids are provided in Table A below.

[0067] Table A.

[0068]

[0069]

[0070] Plant-based rosin may contain abietic acid, preferably abietic acid. Abietic acid has the empirical formula C0. 19 H 29 COOH, also known as rosin acid or pinoresinic acid. Abietic acid is a common major component of plant rosin. Plant rosin may contain at least 50%, or at least 60%, or at least 70%, or at least 80%, or at least 85% abietic acid, preferably abietic acid, by weight of the plant rosin.

[0071] Plant-based rosins can be classified according to their source. For example, the plant-based rosins disclosed herein can be classified as (and may include) resin rosin, wood rosin, tall oil rosin, or mixtures thereof. Resin rosin can be derived from resin extrusions from trees or other plants and can be obtained by striking or cutting the tree and then collecting and processing the extrusion. Wood rosin can be derived from materials obtained from pine stumps, for example, through solvent extraction and / or distillation. Tall oil rosin is a byproduct of crude tall oil distillation during the sulfate process of wood pulp production when pine trees are pulped.

[0072] For example, suitable plant rosin can be obtained from various pine species, such as Masson pine (Pinus massoniana), slash pine (P. elliotti), longleaf pine (P. palustris), stolonifera (P. taeda), Mexican yellow pine (P. oocarpa), glossy pine (P. leiophylla), Michoacán pine (Pino lacio or P. devoniana), European black pine (P. montezumae), maritime pine (P. pinaster), European red pine (P. sylvestris), Arabian pine (P. halepensis), Benguet pine (P. insularis), Caesars pine (P. kesiya), North American white pine (P. strobus), or mixtures thereof.

[0073] 2. Plant-based rosin derivatives

[0074] The plant-based rosin materials disclosed herein may include plant-based rosin derivatives. Plant-based rosin derivatives can be prepared by chemically modifying plant-based rosin materials such as rosin acids (e.g., abietic acid). Such derivatives can be prepared by esterification, hydrogenation, dimerization, polymerization, saponification, or mixtures thereof. Therefore, plant-based rosin derivatives may include rosin esters, hydrogenated rosin, hydrogenated rosin esters, dimerized rosin, polymerized rosin, or mixtures thereof.

[0075] Plant-based rosin materials can be plant-based rosin esters. Plant-based rosin esters can be the reaction products of plant-based rosin (e.g., rosin acid) and alcohols. An exemplary condensation reaction between three abietic acid molecules and one glycerol molecule is shown below to produce a rosin ester.

[0076]

[0077] The alcohol in the esterification reaction can be a monohydric alcohol, a dihydric alcohol, or a polyhydric alcohol, preferably a dihydric alcohol or a polyhydric alcohol. Suitable monohydric alcohols may include methanol, which reacts with rosin acid to form rosin methyl ester. Suitable dihydric alcohols having two hydroxyl groups may include triethylene glycol. The alcohol may be a polyhydric alcohol containing three or more hydroxyl groups. Suitable polyhydric alcohols may contain a total of three hydroxyl groups (e.g., glycerol), a total of four hydroxyl groups (e.g., pentaerythritol), or a total of six hydroxyl groups (e.g., sorbitol or mannitol). Preferred polyhydric alcohols include glycerol, pentaerythritol, and mixtures thereof.

[0078] The alcohol in the esterification reaction may contain between 1 and 10 carbon atoms, preferably between 1 and 7, more preferably between 1 and 6, even more preferably between 1 and 5, and even more preferably between 3 and 5 carbon atoms. Preferably, the alcohol in the esterification reaction contains at least 2 carbon atoms, preferably 2 to 10, more preferably 2 to 6, and even more preferably 2 to 5 carbon atoms. Preferably, the rosin ester is not a methyl ester.

[0079] The alcohols used in esterification reactions can have relatively low molecular weights. For example, alcohols can have molecular weights of about 32 Daltons to about 300 Daltons, more preferably about 32 Daltons to about 200 Daltons, more preferably about 32 Daltons to about 150 Daltons, and even more preferably about 90 Daltons to about 150 Daltons. Without being bound by theory, it is believed that rosin esters formed from lower molecular weight alcohols may be characterized by relatively lower softening points and / or lower acid values ​​compared to rosin esters formed from relatively higher molecular weight alcohols, thereby achieving better processability and / or properties.

[0080] The alcohol used in the esterification reaction can be glycerol or pentaerythritol. Therefore, plant rosin derivatives can be glycerol rosin esters, pentaerythritol rosin esters, or mixtures thereof.

[0081] Plant-based rosin derivatives can be hydrogenated rosin. Given that many plant-based rosin compounds (e.g., abietic acids) are unsaturated, they tend to be oxidically unstable and may undergo color changes during storage. Hydrogenation can help stabilize rosin and reduce undesirable color changes. Furthermore, hydrogenated rosin tends to have a lighter color than the parent rosin, thus providing greater formulation and aesthetic flexibility.

[0082] Plant-based rosin and / or abietic acid can be partially or fully hydrogenated. Below are examples of reactions involving the partial and full hydrogenation of abietic acid.

[0083]

[0084] The treatment composition may contain at least partially hydrogenated, preferably fully hydrogenated, plant rosin material.

[0085] Plant-based rosin derivatives can be either hydrogenated or esterified. For example, plant-based rosin derivatives can be hydrogenated methyl esters or hydrogenated glycerol esters.

[0086] Plant-based rosin derivatives can be dimerized plant rosins. Dimerization can be used to improve the softening point and / or stability of abietic acids. An exemplary dimerization reaction of abietic acid is shown below.

[0087]

[0088] Because it is difficult or even impossible to completely dimerize rosin samples, rosin dimers often exist together with undimerized rosin acid. Dimeric rosin acid can be further esterified.

[0089] Plant rosin derivatives can be transmitted through ions such as Zi 2+ or Ca 2+ Dimer. For example, zinc resinate is a plant rosin derivative in which two abietic compounds are bound to zinc ions.

[0090] Plant-based rosin derivatives can be rosin-based polymers. As used herein, rosin-based polymers are intended to include compounds comprising rosin-based oligomers, which include three or more monomeric units derived from rosin acid. The polymer can be a main-chain polymer or a side-chain polymer.

[0091] Plant-based rosin derivatives can be rosin soaps, wherein abietic acid reacts with an alkali metal hydroxide (e.g., NaOH or KOH) or an alkaline earth metal hydroxide (e.g., Ca(OH)₂). More broadly, plant-based rosin derivatives can be salts of abietic acid.

[0092] Plant rosin derivatives can be functionalized plant rosins. In other words, plant rosins can be functionalized, in which one or more functional groups are added to the plant rosin.

[0093] Plant-based rosin derivatives may include products of the Diels-Alder reaction, such as the reaction products of rosin acid and maleic anhydride; such reaction products can be polymerized.

[0094] Plant-based rosin derivatives may include phenolic rosins, wherein the rosin reacts with phenol. Plant-based rosin derivatives may include rosin alcohols, wherein one or more carboxyl groups of the carboxyl group of rosin acid are converted to hydroxyl groups.

[0095] Commercially available plant-based rosin derivatives suitable for the compositions and methods disclosed in this invention may include those disclosed in Example 1 of the "Examples" section below.

[0096] b. Beneficial agents

[0097] The particles disclosed herein may contain one or more beneficial agents. As described above, it is believed that when particles are formed, the beneficial agents are embedded and / or encapsulated within a plant-based rosin material. Particle formation can thus improve the stability, delivery, and / or performance of the beneficial agents on target surfaces such as fabrics or hard surfaces. For example, such embedding and / or encapsulation of the beneficial agents can prevent degradation of the beneficial agents and / or undesirable interactions with other components of the liquid consumer product.

[0098] The compositions disclosed herein may comprise a beneficial agent and / or granules containing a level of the beneficial agent at which the beneficial agent provides its intended beneficial effect when the composition is used as intended. For example, the beneficial agent in the granules may be present at a level of about 0.05% to about 10%, or about 0.05% to about 5%, or about 0.1% to about 4% by weight of the composition.

[0099] Beneficial agents may be selected from the group consisting of: fragrance materials, silicone oils, waxes, hydrocarbons, higher fatty acids, essential oils, lipids, skin coolants, vitamins, sunscreens, antioxidants, glycerin, odor reducers, odor control materials, antistatic agents, softeners, insect and moth repellents, colorants, optical brighteners, whitening agents, defoamers, antifoaming agents, UV protectants for fabrics and skin, sun fading inhibitors, antiallergens, waterproofing agents, skin care agents, glycerin, natural active substances, aloe vera, vitamin E, shea butter, cocoa butter, whitening agents, antiperspirant active substances, emollients, skin sensitizers, and mixtures thereof.

[0100] The delivery efficacy of a beneficial agent can be most effective when the agent is relatively hydrophobic.

[0101] The beneficial agents in granules may include fragrance materials, which may contain one or more fragrance raw materials. As used herein, the term "fragrance raw material" (or "PRM") refers to a compound having a molecular weight of at least about 100 g / mol and which may be used alone or in combination with other fragrance raw materials to impart odor, aroma, flavor, or fragrance. Typical PRMs include, in particular, alcohols, ketones, aldehydes, esters, ethers, nitrites, and alkenes, such as terpenes. A list of common PRMs can be found in various references, such as "Perfume and Flavor Chemicals," Volumes I and II; Steffen Arctander Allured Pub. Co. (1994) and "Perfumes: Art, Science and Technology," Miller, PM and Lamparsky, D., Blackie Academic and Professional (1994).

[0102] Suitable fragrance ingredients may include materials such as: geraniol, linalool, linaloyl acetate, pyranol, geraniol acetate, anisaldehyde, citral, citronellol, lily aldehyde, citronellol, rose red oxide, tetrahydrolinalool, hydroxycitronellol, ethyl ionone, menthol, cinnamaldehyde, p-propenyl anisole, vanillin, ethyl vanillin, eugenol, cinnamon oil, carvone, piperaldehyde, and mixtures thereof. Fragrance ingredients may also include naturally derived materials, such as essential oils.

[0103] PRMs are characterized by their boiling point (BP) measured at normal pressure (760 mmHg) and their octanol / water partition coefficient (P), which can be described by logP and determined according to the test methods described below. Based on these properties, PRMs can be classified into Quadrant I, Quadrant II, Quadrant III, or Quadrant IV fragrances, as detailed below. Fragrances with multiple PRMs from different quadrants may be desirable, for example, to provide beneficial aromatic effects at different points of contact during normal use.

[0104] Flavoring raw materials may include flavoring raw materials selected from the group consisting of: flavoring raw materials having a boiling point (BP) below about 250°C and less than about 3 LogP; flavoring raw materials having a BP above about 250°C and greater than about 3 LogP; flavoring raw materials having a BP above about 250°C and less than about 3 LogP; flavoring raw materials having a BP below about 250°C and greater than about 3 LogP; and mixtures thereof. Flavoring raw materials having a boiling point (BP) below about 250°C and less than about 3 LogP are referred to as first-quadrant flavoring raw materials. First-quadrant flavoring raw materials are preferably limited to less than 30% of the flavoring composition. Flavoring raw materials having a BP above about 250°C and greater than about 3 LogP are referred to as fourth-quadrant flavoring raw materials; flavoring raw materials having a BP above about 250°C and less than about 3 LogP are referred to as second-quadrant flavoring raw materials; and flavoring raw materials having a BP below about 250°C and greater than about 3 LogP are referred to as third-quadrant flavoring raw materials. Suitable flavoring ingredients for the first, second, third, and fourth quadrants are disclosed in U.S. Patent 6,869,923B1.

[0105] The processing composition may comprise particles, wherein the beneficial agent includes a fragrance material, wherein the fragrance material comprises about 1% to about 40% of a first quadrant fragrance ingredient and / or about 60% to about 99% of a non-first quadrant fragrance ingredient by weight of the fragrance material.

[0106] The granules disclosed herein can be particularly used to help effectively dissolve certain fragrance ingredients in aqueous consumer product compositions, especially those with relatively low surfactant content, thereby avoiding emulsifiers or other processing steps. In particular, the delivery granules of this disclosure are useful when the active ingredient in the granules contains a hydrophobic fragrance ingredient. The hydrophobic fragrance ingredient may be characterized by a relatively high logP value, for example, greater than about 3.0, and may include materials described above as third-quadrant PRMs, fourth-quadrant PRMs, or mixtures thereof. The active ingredient in the granules may contain at least about 50%, or at least about 60%, or at least about 70%, or at least about 80%, or at least about 90%, or about 100% by weight of the active ingredient, third-quadrant PRMs, fourth-quadrant PRMs, or mixtures thereof. Compositions containing such levels of third and / or fourth quadrant PRM as a beneficial agent for particles may be aqueous and contain at least 60%, or at least 70%, or at least 80%, or at least 90%, or at least 95%, or at least 97% water and / or less than 10%, or less than 5%, or less than 3% surfactant by weight of the composition.

[0109] c. Premix

[0110] Plant-based rosin materials can be combined with one or more beneficial agents in a premix. The premix can be added to a base composition that may contain adjuvant ingredients to form a treatment composition. The treatment compositions of this disclosure may comprise a premix containing plant-based rosin materials and one or more beneficial agents, as described in more detail below.

[0111] The premix may contain about 1% to about 99% of plant rosin material by weight of the premix. The premix may contain about 1% to about 99% of a beneficial agent by weight of the premix. The premix may contain plant rosin material and a beneficial agent in a weight ratio of about 1:99 to about 99:1, preferably about 5:95 to about 95:5, more preferably about 10:90 to about 90:10, more preferably about 20:80 to about 80:20, more preferably about 30:70 to about 80:20, more preferably about 40:60 to about 80:20. It is believed that the beneficial effects increase with a higher plant rosin:beneficial agent weight ratio.

[0112] The premix may contain an emulsifier. The premix may contain about 1% to about 95%, or about 5% to about 95%, preferably about 5% to about 40% by weight of the premix. The premix may contain a plant-based rosin material and an emulsifier in a weight ratio of about 5:95 to about 95:5. The premix may contain a beneficial agent and an emulsifier in a weight ratio of about 5:95 to about 95:5. Suitable emulsifiers may include surfactants, amphiphilic polymers, or mixtures thereof.

[0113] Suitable surfactants may include nonionic surfactants, anionic surfactants, or mixtures thereof, preferably nonionic surfactants. Suitable nonionic surfactants may include alkoxylated surfactants, pyrrolidone-based surfactants (including alkylpyrrolidones, preferably C12-alkylpyrrolidones), alkyl polyglycosides, and mixtures thereof. The preferred HLB value for nonionic surfactants is 3 to 12.5. Suitable commercially available nonionic surfactants may include Lutensol.TM XP 40 (purchased from BASF), Lutensol TM XP 70 (purchased from BASF), Plurafac TM LF224 (BASF), Plurafac TM LF 401 (BASF), Ecosurf TM EH 9(DOW), Neodol TM Surfactants (SHELL), Dobanol TM Surfactant (SHELL), Surfadone TM LP-300 (ASHLAND), Planteren TM APG 600 or a mixture thereof.

[0114] Suitable amphiphilic polymers may include graft copolymers, such as poly(ethylene glycol)-poly(vinyl acetate) graft copolymers, polyvinyl caprolactam-polyvinyl acetate-polyethylene glycol graft copolymers, or mixtures thereof. Commercially available graft copolymers may include... HP 22 or Both can be purchased from BASF.

[0115] Premixes can be prepared by heating plant-based rosin materials. The plant-based rosin materials can be heated to a temperature equal to or above their softening point. Premixes can also be prepared by combining and mixing the heated plant-based rosin materials with beneficial agents.

[0116] To facilitate the homogeneity of the premix, mixing can be carried out in a heated oil bath at a temperature set equal to the softening point of the plant rosin material. As the sample becomes homogeneous, the temperature can be gradually reduced, which helps to minimize the risk of loss of volatile materials (e.g., evaporation of volatile PRM).

[0117] Processing aids, such as emulsifiers as described above, can be added at any suitable point. Preferably, the emulsifier (if any) is combined with the plant-based rosin material before the addition of beneficial agents (e.g., fragrances). This order of addition is believed to improve the ease of homogenization of the mixture.

[0118] As an additional or alternative step to heating, plant-based rosin materials can be ground into small particles and mixed with beneficial agents.

[0119] Once prepared, the premix can be stored at ambient temperature. That is, when using the premix to prepare a final product composition, the premix can be heated, for example, to about 60°C, and then injected into the final product or otherwise combined with the base composition. This heating step is most likely helpful when the premix is ​​characterized by a relatively high rosin:beneficial agent (e.g., fragrance) weight ratio (such as greater than 50:50). When the premix contains, for example, a nonionic surfactant as an emulsifier, the heating step may not be necessary.

[0188] Test methods

[0189] It should be understood that the test methods disclosed in the test methods section of this application should be used to determine the corresponding parameter values ​​of the subject matter claimed by the applicant as claimed and described herein.

[0190] Test method for determining the logarithm (logP) of the octanol / water partition coefficient

[0191] The logarithmic value (logP) of the octanol / water partition coefficient for each PRM in the tested spice blends was calculated. The logP of each PRM was calculated using the Consensus logP Computational Model version 14.02 (Linux), purchased from Advanced Chemistry Development Inc. (ACD / Labs) (Toronto, Canada), to provide dimensionless logP values. The ACD / Labs Consensus logP Computational Model is part of the ACD / Labs Model Suite.

[0192] Softening point test method

[0193] If available, use the softening point of the plant-based rosin material provided by the manufacturer / supplier.

[0194] If the softening point is not available from the manufacturer / supplier, determine it using the version approved on July 1, 2018 and published in July 2018, according to ASTM E28-18, "Standard Test Method for Softening Point of Chemically Derived Resins of Pine." More specifically, follow the reference method provided therein ("Automatic Ring and Ball Method Softening Point Method"). This method is outlined here.

[0195] As used herein (and as described in ASTM E28-18), the softening point is defined as the temperature at which a sample dish held by a horizontal ring (brass with shoulder ring; 19.8 mm inner ring diameter, 23.0 mm outer diameter, as per ASTM method) is forced downward a distance of 25.4 mm (1 in) under the weight of a steel ball (9.53 mm diameter; mass between 3.45 g and 3.55 g) when heated at a rate of 5 °C / min in a water, glycerol, silicone oil, ethylene glycol / water, or glycerol / water bath.

[0196] Sample Preparation: Select a representative sample of the rosin material to be tested. The sample should include flakes, tablets, or freshly broken lumps without oxidized surfaces; avoid containing fine fragments or dust. Melt the sample in a clean container; avoid overheating and prevent air bubbles from being incorporated into the sample. The time from the start of heating to pouring the sample should not exceed 15 minutes. Place the ring bottom-down on a metal surface; the ring can be preheated. Pour the molten rosin sample into the ring so that excess rosin is left to cool. After cooling for at least 30 minutes, remove excess material from the perimeter and top of the ring.

[0197] Bath Liquid: The choice of bath liquid will depend on the softening point (“SP”) of the rosin material. For SP between 35°C and 80°C, use water (distilled or deionized, freshly boiled). For SP between 80°C and 150°C, use USP glycerin. For SP above 80°C, use silicone oil (polydimethylsiloxane-200 fluid, 50 cSt, available from Dow Corning, Midland, MI). For SP up to 35°C, use a 50 / 50 (v / v) mixture of ethylene glycol and distilled water; this bath should be cooled to -25°C in a pre-cooled freezer or isopropyl dry ice bath.

[0198] Test: Use a suitable automated ring-and-ball softening point instrument with a control unit; calibrate according to the manufacturer's instructions. Based on the softening point of the rosin material, provide a stirring rod to a 600 mL beaker and fill it with the bath solution provided above. Set up the equipment, ring, ball, test insert, and support pin according to the manufacturer's recommendations. Verify that the control unit is set for the correct bath solution.

[0199] The heating bath was used to uniformly increase the temperature of the bath liquid at a rate of 5°C / min. The test was completed when the beam was interrupted by the falling ball and the material. The softening point at the temperature displayed on the unit was recorded after the test.

[0200] Acid value test method

[0201] If available, use the acid value of the plant-based rosin material provided by the manufacturer / supplier.

[0202] If not available from the manufacturer / supplier, determine the acid value according to ASTM D465-15 (re-approved in 2020), "Standard Test Method for Acid Value of Pine Chemical Products Including Tall Oil and Other Related Products" (approved June 1, 2020, published June 2020). More specifically, follow the reference method provided therein ("Potential Method"). This method is outlined here.

[0203] Provide a sample of freshly chopped rosin material, which may be further crushed to facilitate weighing and dissolution; fragments with oxidized surfaces and existing rosin dust or powder should not be used. If it is a non-uniform liquid, place it in a closed container with a capillary vent or equivalent and heat it in a hot water bath; the sample may be stirred during heating and used after homogenization and thorough stirring.

[0204] Based on the table below, transfer the prescribed amount of sample to a 400 mL tall beaker; add an appropriate amount of Solvent I and vortex until dissolved, gently heating if necessary. If necessary, add an appropriate amount of Solvent II and cool to near room temperature. Immerse each electrode of the glass electrode pH meter (calibrated / normalized according to the manufacturer's instructions) into the solution. Stir with a stir bar.

[0205] Titrate with a standard alkali solution (0.5N or 0.1N KOH solution), recording the burette and pH meter readings. Add sufficient alkali to bring the pH of the solution to approximately 8. Add alkali in 1.0 mL increments until each addition results in a pH change of approximately 0.3 pH units. Reduce the amount of alkali added to 0.1 mL or less until the endpoint has been reached, as indicated by a significant decrease in pH unit per 0.1 mL of alkali added. Continue titrating in 1.0 mL increments until the inflection point is clearly well-defined.

[0206] The inflection point (the point of maximum pH change per mL of alkali solution) is determined by plotting the relationship between pH readings and the number of milliliters of alkali used, accurate to 0.05 mL. (For even greater accuracy, the pH change per mL can be plotted relative to pH; the peak corresponds to the inflection point.) The inflection point is considered the endpoint of the titration.

[0207] The sample acid value, expressed as milligrams of KOH per gram of sample, is calculated as follows and can be recorded as the nearest integer:

[0208] Acid value = (A × N × 56.1) / B

[0209] Where: A = alkaline solution required for sample titration (in mL); N = equivalent concentration of alkaline solution; B = sample weight (in grams).

[0210] Color grading testing method (Gardner Color)

[0211] If available, use the color grade of the plant rosin provided by the manufacturer / supplier (Gardner Color).

[0212] If unavailable from the manufacturer / supplier, determine the color grade (Gardner color) according to ASTM D6166-12 (reapproved in 2016) "Standard Test Method for Color of Pine Chemicals and Related Products (Instrumental Determination of Gardner Color)" (approved December 1, 2016, published December 2016). This method is outlined here.

[0213] Use an instrument such as the Gardner Color Comparator L, 115V (e.g., BYK) to determine the color of a liquid sample. This instrument measures transmitted color and reports it in Gardner color (or, less preferably, in a color system that can be converted to Gardner color by known methods, such as those disclosed in ASTM D6166-12). Calibrate the instrument according to the manufacturer's instructions.

[0214] To prepare rosin samples for colorimetric analysis, a molten sample of the rosin material is introduced into a glass cuvette (10 mm path, unless the instrument manufacturer specifies a different path length). If the sample is solid, it should contain freshly broken clumps and be free of dust and fine fragments; the solid should be melted (e.g., in an oven, sand bath, or oil bath for 15 minutes or less), taking care to avoid overheating and the introduction of air bubbles. Measurements should be performed while the molten sample is still molten after being introduced into the glass cuvette. If the material is cloudy, it should be filtered.

[0215] Insert the glass cuvette into the instrument and measure the color according to the manufacturer's instructions.

[0216] Flash point test method

[0217] If available, use the flash point of the plant-based rosin provided by the manufacturer / supplier.

[0218] If not available from the manufacturer / supplier, determine the flash point according to ASTM D92-18, "Standard Test Method for Determination of Flash Point and Ignition Point by Cleveland Open Cup Method," as approved on July 1, 2018 and published in July 2018.

[0219] Test method for determining the amount of major rosin acid isomers

[0220] If available, use the amount of the major rosin acid isomers of the plant rosin provided by the manufacturer / supplier.

[0221] If unavailable from the manufacturer / supplier, determine the amount of major rosin acid isomers according to ASTM D5974-15, "Standard Test Method for Determination of Fatty Acids and Rosin Acids in Tall Oil Fractions by Capillary Gas Chromatography," as approved on July 1, 2015, and published in August 2015. This method is outlined here.

[0222] This method uses gas chromatography to determine the level of abietic acid, for example, present in a rosin sample. Prior to chromatographic separation, certain free acids should be converted into more volatile and stable methyl esters. For abietic acid, this conversion can be performed using tetramethylammonium hydroxide (TMAH).

[0223] To prepare the methyl ester, dissolve a rosin sample (if solid, freshly crushed to avoid oxidation) in 0.5 mL to 3.0 mL of a 50:50 ether / methanol mixture (and optionally 2 to 3 drops of toluene), adding 2 to 3 drops of phenolphthalein indicator solution. Titrate the mixture with 6% TMAH solution to a pH of 7.9 to 8.1, or to an initial permanent pink color. If over-titation occurs, the mixture can be back-tied with 5% acetic acid solution (v / v) in methanol. When the solution is injected into the heated injection port of the chromatograph, the tetramethylammonium salt pyrolyzes to the methyl ester.

[0224] Gas chromatograph (GC) equipped with a flame ionization detector (FID) was used and operated under the following conditions: column temperature (oven temperature) - initial temperature 150°C; hold for 5 minutes; heating rate 5°C / min; final temperature 250°C; hold for 10 minutes; injection port temperature, 300°C; injection port liner, glass crack; detector temperature, 325°C; carrier gas, helium; linear gas velocity, 19.5 cm / s to 20.5 cm / s; split ratio, maximum 100:1; detector, FID; hydrogen, 30 mL / min; air, 400 mL / min; makeup gas, 30 mL / min. A high-resolution column was used, preferably a dicyanopropylsiloxane-type liquid with a length of 30 m, an inner diameter of 0.32 mm, and a film thickness of 0.20 μm.

[0225] Prepare calibration standards for the expected presence of myristic acid and high-purity standards for amyristic acid, record the weights, and convert them to methyl esters as described above. To prepare the test sample, accurately weigh approximately 50 mg of the sample and approximately 15 mg of myristic acid into a suitable vial, record the weights, and convert them to methyl esters as described above.

[0226] GC was calibrated using calibration standards (0.5 μL to 1.0 μL), retention times were recorded, and individual relative response factors were calculated. To analyze the test sample, 0.5 μL to 1.0 μL was injected (if necessary, the sample was diluted with additional solvent), the peak areas of all desired peaks were obtained from the chromatogram, and the absolute value of each peak of interest was calculated. The relative percentage of each methyl rosinate present could be determined by dividing the measured peak area of ​​one methyl rosinate by the sum of the areas of all methyl rosinate peaks.

[0227] Fabric treatment methods

[0228] When treating fabrics with the compositions according to this disclosure in the following experiments, unless otherwise specified, the following methods were followed. For each treatment, a washing machine (purchased from Miele) was loaded with a fabric load of approximately 3 kg. The fabric load consisted of approximately 1065 g of knitted cotton fabric and approximately 1065 g of polyester-cotton fabric (50 / 50). Additionally, the fabric load included twenty thick fleece towel tracers, which together weighed approximately 870 g. The washing cycle was performed at 95°C.

[0229] Prior to the test treatment, the load was pretreated twice, each time with a 95°C short cotton cycle using 79g of unfragranted IEC A base detergent (purchased from WFK Testgewebe GmbH), followed by two additional 95°C washes without detergent.

[0230] For the test treatment, the load was washed using a short cotton cycle at 40°C, a rotation speed of 1200 rpm, and 79 g of IEC A base detergent, which was added to a suitable dispenser at the start of the wash cycle. A 40 ml dose of the test fabric treatment composition was added to the suitable dispenser.

[0231] Methods for determining headspace concentration above treated fabrics

[0232] Fabric tracers from the above-described fabric treatment methods can be analyzed at at least two specific contact points via headspace analysis:

[0233] -WFO (Wet Fabric Odor, or WET): Analysis of wet fabrics after the fabric treatment process is completed.

[0234] -DFO (Dry Fabric Odor, or DRY): Analysis of dry fabric after the fabric has been air-dried in a closed room for approximately 24 hours.

[0235] The headspace above the cotton fleece tracer was analyzed using SPME headspace GC / MS (gas chromatography-mass spectrometry). 4cm × 4cm aliquots of the cotton tracer were transferred to 25ml headspace vials. The fabric samples were equilibrated at 65°C for 10 minutes. The headspace above the fabric was sampled for 5 minutes via SPME (50 / 30μm DVB / Carboxen / PDMS). The SPME fibers were then immediately thermally desorbed into the GC. The analytes were analyzed by GC / MS in full scan mode. The total fragrance HS response and fragrance headspace composition above the test group were determined.

[0236] Viscosity method

[0237] The viscosity of the liquid composition was measured using a DV-E viscometer purchased from Brookfield. The mandrel rotated automatically at a rate of 60 rpm until a stable value in centipoises (cP) was given.

[0238] Viscosities of premixes containing rosin plant material, delivery agents, and potential emulsifiers were measured using HAAKE MARS, purchased from Thermo Scientific, with a 60 mm 1° cone and a 52-micron gap size. (20s) -1 The shear viscosity at 21°C can be increased from 0.01 s⁻¹. -1 up to 1200s -1 The viscosity was obtained by scanning the logarithmic shear rate. Viscosity can be expressed as centipoise (cP).

[0239] Particle size determination

[0240] Depending on the relative size of the particles, one of two methods is employed: if the approximate volume-weighted median particle size of the population is 10 μm or larger, image analysis is performed; or if the approximate volume-weighted median particle size of the population is less than 10 μm, microscopy is used. These methods will be described in more detail below.

[0241] A. Image Analysis

[0242] The volume-weighted median particle size is calculated from images taken from samples flowing through a variable-size flow cell. This instrument (Occhio FC200S) is specifically designed for liquid applications using an image analysis unit. The sample is pumped through the flow cell at a very low rate via a syringe pump, and images are captured at set intervals while the sample is passing through the flow cell. This rate matches the camera's frame rate and depends on the behavior of the sample and the particles it contains. The flow cell sizes used are 250 μm and 500 μm, depending on the capsule size. Capsules are detected using a grayscale threshold. Callisto version 2013.13 software is used to read out pixels and calculate size and shape parameters. The size descriptor used is the ISO area diameter.

[0243] The illumination is provided by a red LED light source, and the illumination is adjusted manually until proper grayscale detection of the particles is achieved. The hardware magnification depends on the particle size: 6x or 9x.

[0244] B. Microscopic method

[0245] The volume-weighted median particle size was calculated by observing and measuring the diameters of approximately 900 capsules in randomly sampled aliquots under a microscope. The microscope used was a Leica DM6000B. The microscope magnification was set to 200x. The outputs obtained after microscopic analysis were: (1) a list of detected diameters; and (2) a count of each detected diameter size.

[0246] Therefore, the volume (V) of each particle is calculated by the following formula:

[0247]

[0248] Where r is the radius of each detected particle. Finally, assuming each particle is a sphere, the volume-weighted median granularity is calculated (e.g., via a spreadsheet such as Microsoft Excel). TM Those created in (the middle).

[0249] Example

[0250] The embodiments provided below are intended to be illustrative in nature and are not intended to be limiting.

[0251] Example 1. Exemplary plant-based rosin material

[0252] Table 1 shows a variety of commercially available plant-based rosin materials. This information will be provided where additional details are available.

[0260] Example 2. Exemplary liquid fabric conditioning product containing particles

[0261] The LFE formulations in Table 2A below are examples of liquid fabric strengthening agent products containing particles. Exemplary liquid fabric conditioning products are prepared by adding fragrance and plant rosin materials to a base composition via a premix comprising a 50:50 ratio of fragrance and glyceryl ester resin.

[0264] 1 Diester quaternary ammonium compound (Ci-DEEDMAC = ditaurate ethoxy ester dimethyl ammonium chloride [MDEA-based, methyl diethanolamine quaternary ammonium compound, purchased from Evonik])

[0265] a. Microscopic method

[0266] Photomicrographs of the liquid product composition were taken at 63X magnification using a fluorescence confocal laser scanning microscope (CLSM). Figure 1 Representative micrographs are shown, in which particles with diameters ranging from approximately 5 to 14 micrometers are observed.

[0267] It is believed that the plant-based rosin material and fragrance are co-located within the particles for at least the following reasons. First, the particles are visible under an optical / confocal microscope. The fragrance can be stained with coumarin, and co-location with the particles was observed using different filters and detectors on the microscope. Furthermore, the presence of rosin material within the particles was confirmed by squeezing the particles with a microscope slide. When sufficient pressure was applied to cause the particles to collapse, rosin (observed as a viscous / sticky substance) could be identified at the same location as the fragrance.

[0268] b. Product headspace

[0269] Furthermore, the fragrance concentration in the headspace of the product composition can be analyzed. Compared to rosin-free formulations, less fragrance was found in the headspace of formulations containing a rosin / fragrance premix. This indicates that the rosin interacts with the fragrance, preventing it from evaporating from the formulation and entering the headspace.

[0270] c. Particle size

[0271] Additionally, the presence of capsules in the final liquid fabric reinforcing agent product (e.g., the amount varies according to the formulation in Table 2A) can be assessed using the particle size characterization methods described in the "Test Methods" section. Depending on the particle size range, one of two methods is employed: image analysis or microscopy.

[0272] Groups 1, 2, and 3 differ in the levels of resins, fragrances, and emulsifiers; the percentage levels provided below are based on the weight of the final product (“FP”). For Groups 1 and 2, the presence of large particles necessitates image analysis methods, while for Group 3, the particles are relatively small, thus microscopic methods are preferred. Particle sizes at different points in the volume-weighted particle size distribution (PSD) are provided in Table 2B. For each of the three groups, the median particle size (at 50% volume-weighted distribution) is reported in Table 2B.

[0273] Table 2B .

[0274]

[0275] As shown in Table 3, relatively more plant-based rosin materials tend to produce relatively larger particles; see Groups 1 and 2 for example. Additionally, it is believed that emulsifiers such as Surfadone... TM The presence of [something] promotes the formation of relatively small particles.

[0276] Example 3. Ratio of plant-based rosin to beneficial agents

[0277] The following rosin / fragrance premixes were prepared as shown in Table 3. These weight percentages are based on the weight of the premix compositions.

[0278] A premix is ​​provided at the same total amount of fragrance as that provided to the liquid fabric reinforcement (LFE) base composition; the total amount of fragrance present in the resulting liquid fabric (LFE) composition is 0.6% by weight. The resulting liquid conditioning product is used to treat fabrics according to the method provided above.

[0279] Headspace analysis was used to evaluate dry fabric odor (DFO), and the results are presented in Table 3.

[0280] Table 3 .

[0281]

[0282] As shown in Table 3, the flavor in the headspace (nM / L) of DFO increases with the amount of plant rosin material in the premix.

[0283] In addition, photomicrographs of the final liquid conditioning products prepared using premixes 1, 2, 3, and 4 were obtained using polarized transmitted light at 10X magnification. Figure 2A As shown, no particles are visible in the liquid composition prepared using premix 1, which does not contain plant rosin materials. Figures 2B to 2D As shown, particles are visibly present in premix 2 ( Figure 2B ), premix 3 ( Figure 2C ) and premix 4 ( Figure 2D In liquid compositions prepared by ), it appears that in compositions containing premixes with a relatively large amount of plant rosin material, the particles are relatively large; see, for example, premix 3 ( Figure 2C ) and premix 4 ( Figure 2D Micrographs of the prepared product.

[0291] The following rosin / fragrance premixes were prepared, some of which contain emulsifiers, as shown in Table 4B. These weight percentages are based on the weight of the premix compositions.

[0293]

[0294] Various liquid fabric conditioning products were prepared using the premixes in Table 4B and added to the compositions in Table 4A. For each group, a parallel product with only fragrance added (no premix; no plant rosin material) was prepared and used as a reference product. The premixes in Table 4B were added in an amount such that the same amount of fragrance was delivered relative to the reference product (no premix; no plant rosin material). This can be done by top mixing or with... The premix is ​​added to the composition in Table 4A during mixing.

[0295] Table 4C .

[0296]

[0297] The products were used to treat fabrics according to the methods provided above, and the dry fabric odor (DFO) of each product was measured. The formulation of the LFE compositions is reported in Table 4B:

[0298] The results are provided in Table 4D below. Additionally, Table 4D shows “ΔDFO,” which illustrates the difference in DFO scores between products containing the premix from Table 4B and products containing only flavoring. Furthermore, the “DFO ratio” is the ratio of the two DFO scores within this group. Relatively high ΔDFO scores and DFO ratios indicate that formulations containing premixes provide a beneficial effect on freshness compared to flavoring-only formulations.

[0299] Additionally, comments on the dispersibility of the premixes are provided based on observations made when attempting to disperse the premixes into LFE-based compositions. Premix 16 was not tested.
