Description

[Technical Field]

[0001] (Cross-reference of related applications) This application claims priority under U.S. Provisional Application No. 63 / 578,686, filed on 25 August 2023, pursuant to 35 United States Code, Section 119. This Provisional Application is incorporated herein by reference in its entirety.

[0002] (Field of invention) This disclosure relates, as a whole, to detergents and cleaning compositions for the removal of hydrophobic stains. More specifically, this disclosure relates to detergents and cleaning compositions comprising an insoluble solvent and a surfactant for incorporating the insoluble solvent into the composition at low concentrations, thereby overcoming various challenges in formulations using insoluble solvents. Various methods of use of the compositions are also provided, including applications for use in removing difficult hydrophobic stains such as those found in various cosmetics, deodorants, and sunscreens, which are known to be difficult to remove using conventional aqueous detergents and cleaning compositions. [Background technology]

[0003] The cleaning and removal of various cosmetic, deodorant, and sunscreen stains presents challenges because many of these stains are insoluble and contribute to long-lasting effects. Cosmetic stains, including those on cosmetic manufacturing equipment, are an example of this stain removal challenge because the stains are difficult to penetrate and emulsify. A wide variety of manufacturing equipment for all kinds of different cosmetic products, along with other surfaces (e.g., laundry) soiled with these products, require cleaning.

[0004] The cosmetics industry most frequently uses alkaline or acidic cleaning products in its manufacturing equipment. Traditionally, aqueous alkaline or acidic detergent compositions have been used in industrial cleaning processes. These detergents typically contain either an alkaline or acidic source, as well as a blend of ingredients that may include surfactants, chelating agents, metal ion sequestering agents, dispersants, coupling agents, polar solvents with high water solubility, and other functional ingredients.

[0005] These alkaline or acidic cleaning products do not work equally well on all types of cosmetic stains. As a result, manufacturers of many different cosmetic products either have to purchase many different cleaning products to effectively remove stains, or / or achieve only inadequate cleaning for all stains. In addition, the fast-paced cosmetics industry requires manufacturers to frequently improve existing products, which may also necessitate improved cleaning products and procedures to avoid inadequate stain removal. Inadequate cleaning and detergent compositions are not uncommon in the cosmetics industry. Consequently, there are no cost-effective cleaning and detergent compositions, and the selection of detergents and cleaning compositions is limited.

[0006] In addition, while water-based detergents are effective at cleaning water-soluble stains and some oils or fats that can be emulsified, they have significant limitations that arise when the stain contains components that are highly water-insoluble and difficult to emulsify. In these cases, solvents are typically required. However, solvents typically cannot be diluted with water and are instead used at 100% concentration. Solvents can also be hazardous due to their high flammability. Furthermore, solvents are not sustainable or biodegradable products.

[0007] Therefore, the object of this disclosure is to provide detergents and cleaning compositions for removing hydrophobic stains.

[0008] A further object of this disclosure is to provide effective detergents and cleaning compositions that use insoluble solvents that offer formulation benefits, safety benefits, and sustainability benefits.

[0009] A further object of this disclosure is to provide detergents and cleaning compositions that offer superior efficacy compared to conventional solvents, i.e., polar solvents that have high water solubility and lack a specified range of LogP and total polar surface area as described herein in accordance with the present invention.

[0010] A further object of this disclosure is to provide a cleaning method using detergents and cleaning compositions that enable cleaning of manufacturing equipment for all kinds of different cosmetic products (and other insoluble or difficult-to-emulsify products).

[0011] Other objects, aspects and advantages of the present invention will be apparent to those skilled in the art in consideration of the following disclosures, drawings and appended claims. [Overview of the project]

[0012] The primary object, features, and / or advantages of this disclosure are to improve or overcome the shortcomings of the art in cleaning and removing various hydrophobic stains, such as cosmetic stains. The combination of hydrophobic solvents and surfactants in a composition, replacing conventional solvents that are unable to remove hydrophobic stains, is an advantage of detergents and cleaning compositions. This advantage is further provided in cleaning methods using detergents and cleaning compositions, thereby enabling the cleaning and removal of stains that are highly water-insoluble and difficult to emulsify. A further advantage is the ability to use diluted solvents instead of using them at 100% concentration, overcoming formulation, safety, and sustainability challenges.

[0013] According to some aspects of this disclosure, detergents and cleaning compositions comprise an insoluble solvent and an alkyl polyglycoside surfactant and a co-surfactant or co-solvent for providing an emulsion.

[0014] According to some additional aspects of this disclosure, the method of use includes applying the compositions described herein to a surface that requires stain removal. The stains are hydrophobic and / or oily.

[0052] composition According to the embodiments, detergents and cleaning compositions comprise an insoluble solvent and a surfactant, and optionally additional functional components. The compositions may contain additional functional components and may be provided as concentrates or compositions for use. Exemplary compositions are shown in weight percentages in Tables 1A and 1B. Note that while components may have 100% active substance percentages, Tables 1A and 1B do not list the active substance percentages of the components, but rather the total weight percentages of the raw materials (i.e., active substance concentration + inactive component).

[0053] [Table 1A]

[0054] [Table 1B]

[0055] Detergents and cleaning compositions are mixtures of two or more immiscible liquids that exhibit varying levels of stability at different concentrations, temperatures, and alkalinity levels. In embodiments, the detergent and cleaning composition is combined with a diluent, such as water added to the emulsion, to provide a diluted concentration in water at some point in the method, at a concentration of about 0.5–20%, about 1–10%, or preferably about 1–6%, and may be further mixed or stirred to maintain dispersion. The detergent and cleaning composition remains in the emulsion during use, which balances the challenge of stabilizing the insoluble solvent while also ensuring access of the dirt to the solvent for cleaning. Excessive emulsification can adversely affect dirt removal (i.e., performance) by limiting the access of the insoluble solvent to the dirt itself.

[0056] The composition has a suitable neutral pH of about 6 to about 9. The composition is beneficially biodegradable, safe for use, safe for soft metals (also known as soft metal compatibility), and has lower VOC (volatile organic compound) levels than commercially available detergent compositions. In preferred embodiments, the composition meets EPA requirements for vapor pressure (i.e., 0.0 mbar for 2-ethylhexyl lactate) and boiling point (i.e., about 243°C for 2-ethylhexyl lactate) measured at 20°C. Compositions using insoluble solvents provide low vapor pressure and high boiling point, and offer low VOCs.

[0057] Beneficially, the composition allows formulations using insoluble solvents to provide effective cleaning with low concentrations of surfactant without the need to use water as a diluent. In some embodiments, the emulsion composition does not have water added as a diluent or solvent (apart from any water from the aqueous components of the raw materials). In one embodiment, the concentrated composition (all components in the formulation) is diluted with water to a concentration of about 0.5 to 20%, about 1 to 10%, or preferably about 1 to 6%.

[0058] insoluble solvent Detergents and cleaning compositions contain an insoluble solvent. As described herein, an insoluble solvent refers to a solvent that cannot form a solution with another substance(s). An insoluble solvent contains at least one polar functional group. Exemplary polar functional groups include hydroxyl, methyl, carboxyl, carbonyl, amino, or phosphate groups. Examples of such insoluble solvents containing an exemplary polar functional group include, but are not limited to, glycol ether solvents, alcohol solvents, ester solvents, fatty acid solvents, fractions (petroleum), and mixtures thereof.

[0059] Insoluble solvents can be further defined according to a partition coefficient P, which is defined as the ratio of the equilibrium concentrations C of chemical substances dissolved in a two-phase system consisting of two immiscible solvents. The logarithm of the partition coefficient, LogP, represents the hydrophobicity of the solvent. According to embodiments herein, insoluble solvents have varying water solubility, which can be evaluated by the LogP of the solvent, as described above, with higher LogP indicating less soluble solvents. In one embodiment, the insoluble solvent has a LogP ≥ 1.75, and in some difficult-to-remove embodiments, it has a LogP ≥ 4.

[0060] Insoluble solvents can be further defined according to their topological polar surface area, which is the amount of surface area of ​​a molecule derived from polar atoms (generally in angstroms, Å). 2 (Measured by...). Topological polar surface area is obtained by subtracting the area of ​​carbon, halogen, and nonpolar hydrogen atoms (i.e., hydrogen atoms bonded to carbon atoms) from the molecular surface, thereby leaving heteroatoms and polar hydrogen atoms.

[0061] Water solubility is influenced by the water polarity of the solvent. The solvents described herein are preferably limited in water polarity. While solvents are generally referred to as insoluble solvents, some degree of water polarity is necessary. The limited water polarity is determined based on the total polar surface area having oxygen atoms (i.e., polar functional groups) that impart some polarity, as described above as topological polar surface area. The insoluble solvents with the best performance have different chemical structures and classifications, while LogP ≥ 1.75 and a topological polar surface area (Å). 2 The value of ) is approximately 50 or less (including 0). The need for some polar functional groups is demonstrated in the examples by solvents that do not have polar functional groups and are ineffective.

[0062] In a preferred embodiment, the insoluble solvent having the best cleaning performance is one with a LogP ≥ 1.75 and a topological polar surface area (A) of about 50 or less, or preferably about 0 to 50. 2 ) has.

[0063] In preferred embodiments, the insoluble solvent is one or more of the following: 2-ethylhexyl L-lactic acid, tripropylene glycol butyl ether, hexanol, 2-2(2-ethylhexyloxy)ethanol, octanoic acid, and distillates (petroleum), hydrogenated light distillates. Such insoluble solvents are commercially available. Commercially available insoluble solvents include Purasolv EHL, 2-ethylhexyl L-lactic acid and Purasolv EL, ethyl lactate (both available from Corbion), 2-2(2-ethylhexyloxy)ethanol (CAS 1559-35-9), also known as ethylene glycol 2-ethylhexyl ether, and Isopar M (CAS 64742-47-8) and other petroleum fractions.

[0064] In a more preferred embodiment, the insoluble solvent is 2-2(2-ethylhexyloxy)ethanol, which is beneficially stable under alkaline conditions.

[0065] In some embodiments, the insoluble solvent is included in the concentrated detergent and cleaning composition in amounts of at least about 10% to about 80% by weight, 15% to about 80% by weight, 20% to about 80% by weight, about 35% to about 80% by weight, about 35% to about 75% by weight, or about 35% to about 70% by weight. In addition, although not limited by this disclosure, all enumerated ranges include a number defining the range, and each integer within that defined range.

[0066] In embodiments, detergents and cleaning compositions may contain an insoluble solvent that can be emulsified in water when diluted. Beneficially, nonpolar solvents, when diluted with water, produce diluted solutions used for cleaning a variety of surfaces, providing benefits beyond conventional nonpolar solvents at 100% concentration, which are conventional formulations for detergents and cleaning compositions. For example, detergents and cleaning compositions are formulated as concentrated formulations that are diluted with water to low concentrations (i.e., 1% or even lower in embodiments). In most embodiments, the working solution concentration of the composition is provided at about 1% to 10% working solution, which may vary depending on factors such as the type of dirt being cleaned.

[0067] surfactants Detergents and cleaning compositions include a surfactant in combination with an insoluble solvent. In embodiments, the surfactant includes alkyl polyglucosides (APGs) and / or amphoteric surfactants. Beneficially, the surfactant allows the insoluble solvent to be emulsified in water when diluted.

[0068] In embodiments, the surfactant is included in the detergent and cleaning composition in an amount of at least about 1% to about 80% by weight, about 1% to about 70% by weight, about 1% to about 60% by weight, about 1% to about 50% by weight, or about 10% to about 50% by weight. In addition, although not limited by this disclosure, all enumerated ranges include a number defining the range, and each integer within the defined range.

[0069] Alkyl polyglycoside (APG)

[0070] Detergents and cleaning compositions contain one or more alkyl polyglycoside surfactants in combination with an insoluble solvent. Alkyl polyglycosides are characterized by one or more monosaccharide units and at least one hydrophobic alkyl group attached to one of the hydroxyl groups of the sugar unit. These molecules differ in sugar units, degree of polymerization (DP) of the sugar units, number of alkyl groups, alkyl chain length, and whether they are linear or branched. Preferred APGs include alkyl polyglucosides characterized by a glucose sugar moiety.

[0071] Alkyl polyglycosides are widely used as nonionic surfactants in a variety of cosmetics, household products, and industrial applications. The alkyl polyglycosides that may be used in this invention are fatty ether derivatives of sugars or polysaccharides formed when carbohydrates react with fatty alcohols via condensation polymerization under acidic conditions and high temperatures. Alkyl polyglycoside surfactants typically feature one or more sugar units, one end of which is hydrophilic and the other end of which is a hydrophobic alkyl group. They are usually derived from polysaccharides from natural resources, and the raw materials are typically starch and fat. The final product may be a complex mixture of compounds having different sugar moieties, including one or more hydrophilic alkyl groups from fatty alcohols.

[0072] In embodiments, APG preferably comprises a hexose or pentose sugar or polysaccharide group (i.e., sugars such as monosaccharides, disaccharides, and trisaccharides) and an aliphatic alipid group having 6 to 20 carbon atoms. Alkyl polyglycosides that may be used in the present invention have the general formula: (G) x-O-R Represented by the formula, where G is a reducing sugar containing 5 or 6 carbon atoms, such as a pentose or hexose derived from a reducing sugar. R is an aliphatic group containing 6 to 20 carbon atoms, and x is the degree of polymerization (DP) of the polyglycoside, representing the number of monosaccharide repeating units in the polyglycoside. Generally, x is an integer based on individual molecules, but since there is statistical variation in the APG manufacturing process, x may be a non-integer based on the average.

[0073] In one embodiment, the APG used in the detergent and cleaning composition preferably has an x ​​value of less than about 5, more preferably between about 0.5 and about 5. Even more preferably, x is less than about 2.5, and more preferably in the range of about 1 to about 2.

[0074] Commercially available alkyl polyglycosides may contain a blend of carbon lengths. A preferred alkyl polyglycoside is C 16 It includes alkyl polyglycosides containing short-chain carbons such as those with a chain length of less than C8. In one example, a suitable alkyl polyglycoside is C8~C8.16 This includes alkyl polyglycosides. Further descriptions of suitable alkyl polyglycosides are, for example, in U.S. Patents 8,697,622, 8,658,584, 8,557,760, 8,389,457, 8,287,659 and 8,299,009, and U.S. Patent Publications 2013 / 0023458 and 2012 / 0322710, which are incorporated herein by reference in their entirety.

[0075] Exemplary monosaccharides from which G is derived are glucose, fructose, mannose, galactose, talose, gros, allose, altrose, idose, arabinose, xylose, lyxose, and ribose. Glucose is preferred in the preparation of polyglycosides because it is readily available. Faliphatic groups, which are substituents of preferred polyglycosides, are preferably saturated, but unsaturated aliphatic groups may also be used.

[0076] Preferably, the APG has an average degree of polymerization of 1.4–1.7 of sugars, and the chain length of the aliphatic group is between C8 and C16. Commercially, alkyl polyglycosides can be supplied as concentrated aqueous solutions with an activity range of 50–70% by weight. Examples of commercial suppliers of alkyl polyglycosides are Dow, BASF, Seppic, Akzo Nobel, and Croda.

[0077] Alkyl polyglycosides can act as emulsifiers. Emulsifiers are amphiphilic surfactant compounds that have both hydrophilic and hydrophobic moieties. The ratio of hydrophilic to hydrophobic moieties in a compound is generally expressed as the hydrophilic-lipophilic balance, or HLB. A low HLB range (i.e., 3–6) tends to indicate a water-in-oil emulsion, while a higher HLB range (i.e., 8–18) tends to indicate an oil-in-water emulsion.

[0078] In preferred embodiments, the alkyl polyglycoside has at least about 8, at least about 9, or at least about 10 HLB. In further embodiments, the alkyl polyglycoside has about 8 to about 18, about 9 to about 18, or about 10 to about 18 HLB. An exemplary natural fatty alcohol-based alkyl polyglycoside is the C10-C16 alkyl polyglycoside commercially available as Glucopon® 600UP (BASF).

[0079] In embodiments, the composition includes a combination of two or more alkyl polyglycosides, such as a low-HLB alkyl polyglycoside surfactant (e.g., HLB < 10) and a high-HLB alkyl polyglycoside surfactant (e.g., HLB > 10). For example, in one embodiment, the composition may include two or more alkyl polyglycosides, including sorbitan monolaurate (HLB 9) and / or sorbitan monooleate (HLB 4), in combination with a high-HLB surfactant (i.e., C8-C10 APG with HLB 14 and / or C7 APG with HLB 14).

[0080] In embodiments, the APG surfactant is included in detergents and cleaning compositions in amounts of at least about 1% to about 30% by weight, about 5% to about 30% by weight, about 5% to about 25% by weight, or about 5% to about 20% by weight. In addition, although not limited by this disclosure, all enumerated ranges include a number defining the range, and each integer within the defined range.

[0081] Amphoteric surfactants

[0082] In many embodiments, detergents and cleaning compositions contain an amphoteric cosurfactant in combination with an insoluble solvent, which beneficially provides solubility of APG with the insoluble solvent. It was unexpected to discover that the amphoteric surfactant not only provides improved performance but also allows for the formulation of emulsions of APG and the insoluble solvent. In other embodiments, a cosolvent such as an alcohol may replace the amphoteric cosurfactant.

[0083] Amphoteric or amphoteric electrolyte surfactants contain both basic and acidic hydrophilic groups as well as organic hydrophobic groups. These ionic entities may be either anionic or cationic groups as described herein for other types of surfactants. Basic nitrogen and acidic carboxylate groups are typical functional groups employed as basic and acidic hydrophilic groups. In some surfactants, sulfonates, sulfates, phosphonates, or phosphates provide a negative charge.

[0084] Amphoteric surfactants can be broadly described as derivatives of aliphatic secondary and tertiary amines, in which the aliphatic radical may be linear or branched, and one of the aliphatic substituents contains about 8 to 18 carbon atoms, and the other contains an anionic water-soluble group, such as carboxy, sulfo, sulfato, phosphato, or phosphono. Amphoteric surfactants are known to those skilled in the art and are subdivided into two main classes, as described in the "Surfactant Encyclopedia" Cosmetics & Toiletries, Vol. 104(2) 69-71 (1989), which is incorporated herein by reference. The first class includes acyl / dialkylethylenediamine derivatives (e.g., 2-alkylhydroxyethylimidazoline derivatives) and their salts. The second class includes N-alkyl amino acids and their salts. Some amphoteric surfactants may be conceivable to belong to both classes.

[0085] Amphoteric surfactants can be synthesized by methods known to those skilled in the art. For example, 2-alkylhydroxyethylimidazoline is synthesized by condensation and ring closure of a long-chain carboxylic acid (or derivative) with a dialkylethylenediamine. Commercial amphoteric surfactants are derivatized, for example, with chloroacetic acid or ethyl acetate, by subsequent hydrolysis and ring opening of the imidazoline ring by alkylation. During alkylation, one or two carboxyalkyl groups react to form a tertiary amine and an ether linkage, and different alkylating agents produce different tertiary amines.

[0086] The long-chain imidazole derivatives useful in the present invention generally have the following general formula,

Chemical Formula

Chemical Formula

[0087] The carboxymethylated compounds (glycinates) recited herein above are often referred to as betaines. Betaines are a special class of amphoteric materials discussed herein. Amphoteric surfactants suitable for use in the present compositions include betaines of the following general structure:

Chemical Formula

[0088] Long-chain N-alkyl amino acids, or iminodipropionates, are classified as RNH2 (wherein R is C8-C). 18 These are readily prepared by the reaction of a fatty amine (which is a linear or branched alkyl group) with a halogenated carboxylic acid. Alkylation of the primary amino group of an amino acid yields secondary and tertiary amines. The alkyl substituent may have an additional amino group that provides one or more reactive nitrogen centers. The most commercially available N-alkylamine acids are alkyl derivatives of beta-alanine or beta-N(2-carboxyethyl)alanine. Examples of commercially available N-alkylamino acid amphoteric electrolytes that have applications in the present invention include alkyl beta-aminodipropionates, RN(C2H4COOM)2 and RNHC2H4COOM. In embodiments, R may be an acyclic hydrophobic group containing about 8 to about 18 carbon atoms, while M is a cation to neutralize the anion's charge. Preferred iminodipropionates include sodium octyliminodipropionate or alkyliminodipropionic acid. Exemplary iminodipropionates are marketed as Tomamine Amphoteric 12 (Evonik Industries) and Tomamine® Amphoteric 400 (Evonik Industries) (registered trademark).

[0089] Suitable amphoteric surfactants include those derived from coconut products such as coconut oil or coconut fatty acids. Additional suitable coconut-derived surfactants include, as part of their structure, an ethylenediamine moiety, an alkanolamide moiety, an amino acid moiety, e.g., glycine, or a combination thereof, and an aliphatic substituent with about 8 to 18 (e.g., 12) carbon atoms. Such surfactants may also be considered alkylamphodicarboxylic acids. These amphoteric surfactants are C 12 -alkyl-C(O)-NH-CH2-CH2-N + (CH2-CH2-CO2Na)2-CH2-CH2-OH or C 12 -alkyl-C(O)-N(H)-CH2-CH2-N + It may include a chemical structure represented as (CH2-CO2Na)2-CH2-CH2-OH. Disodium cocoamphodipropionate is one preferred amphoteric surfactant, marketed under the trademark name Miranol® FBS by Rhodia Inc., Cranbury, NJ. Another preferred coconut-derived amphoteric surfactant having the chemical name disodium cocoamphodiacetate is similarly marketed under the trademark name Mirataine® JCHA by Rhodia Inc., Cranbury, NJ.

[0090] Further examples are provided in “Surface Active Agents and Detergents” (Vol. I and II by Schwartz, Perry and Berch), which is incorporated in its entirety by reference herein.

[0091] In some embodiments, the compositions or detergent compositions disclosed herein do not contain amphoteric surfactants.

[0092] In embodiments, amphoteric surfactants are included in detergents and cleaning compositions in amounts of at least about 1% to about 40% by weight, about 5% to about 40% by weight, about 10% to about 40% by weight, or about 10% to about 35% by weight. In addition, although not limited by this disclosure, all enumerated ranges include a number defining the range, and each integer within the defined range.

[0093] Chelating agents Detergents and cleaning compositions may optionally contain chelating agents. Examples of chelating agents include, but are not limited to, chelating agents (chelators), sequestering agents (sequestrants), and detergent builders. Examples of chelating agents include, but are not limited to, phosphonates, phosphates, aminocarboxylates and their derivatives, pyrophosphates, polyphosphates, ethylenediamines and ethylenetriamine derivatives, hydroxy acids, and mono-, di-, and tri-carboxylates, and their corresponding acids. Other exemplary chelating agents include aluminosilicates, nitroloacetates and their derivatives, and mixtures thereof.

[0095] The chelating agent may be water-soluble and / or biodegradable. Other exemplary chelating agents include TKPP (tetrapotassium pyrophosphate), PAA (polyacrylic acid) and its salts, phosphonobutanecarboxylic acid, alanine, N,N-bis(carboxymethyl)-, trisodium salt, and sodium gluconate.

[0096] In some embodiments, the chelating agent is phosphorus-free. Preferably, the chelating agent is a sodium salt of an aminocarboxylate. More preferably, the chelating agent is methylglycine diacetic acid (MGDA).

[0097] In some embodiments, the compositions disclosed herein do not contain chelating agents.

[0098] In embodiments, the chelating agent is included in the detergent and cleaning composition in amounts of at least about 0% to about 30% by weight, about 0% to about 25% by weight, about 0% to about 20% by weight, about 1% to about 20% by weight, or about 1% to about 10% by weight. In addition, although not limited by this disclosure, all enumerated ranges include a number defining the range, and each integer within the defined range.

[0099] Additional functional ingredients The components of detergents and cleaning compositions can be further combined with various functional components suitable for the applications disclosed herein. In some embodiments, a composition comprising an insoluble solvent, a surfactant, and optionally a chelating agent constitutes the majority, or even substantially all, of the total weight of the detergent and cleaning composition. For example, in some embodiments, little to no additional functional components are present in the composition.

[0100] In other embodiments, additional functional components may be included in the detergent and cleaning compositions. Functional components provide the composition with desired properties and functionality. For the purposes of this application, the term “functional component” includes materials that, when dispersed or dissolved in a working solution such as an aqueous solution and / or a concentrated solution, provide properties beneficial in a particular use. Several specific examples of functional materials are discussed in more detail below, but the specific materials discussed are given merely as examples, and a wide variety of other functional components may be used. For example, many of the functional materials discussed below relate to materials used for cleaning. However, other embodiments may include functional components for use in other applications.

[0101] In some embodiments, the detergent composition may include optical gloss agents, defoaming agents, anti-redeposition agents, bleaching agents, solubility modifiers, dispersants, metal protectants, stain redeposition inhibitors, stabilizers, corrosion inhibitors, builders / metal ion sequestering agents / chelating agents, aesthetic enhancers including enzymes, fragrances and / or dyes, additional rheological and / or solubility modifiers, diluents or thickeners, hydrotropes or couplers, buffers, solvents, additional cleaning agents, and the like.

[0102] In one embodiment, the additional cleaning agent may include a basic alkaline cleaning agent, such as an alkali metal hydroxide. However, in a preferred embodiment, the alkaline component, such as an alkaline cleaning agent, is combined at the point of use as a separate booster in a two-part system in order to effectively maintain a neutral pH of the composition.

[0103] In one embodiment, additional diluents, such as propylene glycol and / or glycerin, may be included.

[0104] According to embodiments of the present disclosure, various additional functional components may be provided in the composition in amounts of about 0% to about 50% by weight, about 0.01% to about 50% by weight, about 0.1% to about 50% by weight, about 1% to about 50% by weight, about 1% to about 30% by weight, about 1% to about 25% by weight, or about 1% to about 20% by weight.

[0106] How to use

[0107] The cleaning method is particularly well suited for removing hydrophobic and / or oily stains, such as cosmetic stains. Cosmetic stains, as referred to herein, include, for example, lipstick, lip gloss, mascara, sunscreen, clay mask, deodorant, and hair treatment compositions. While not limited to specific theories or mechanisms of action, the hydrophobic portion of various cosmetic stains is considered to be particularly difficult to remove from surfaces. For example, the hydrophobic portion of a cosmetic stain (e.g., lipstick) may be in the form of oil, viscous solid, silicone, or wax, depending on the desired consistency of the cosmetic product. For example, lip gloss rolled on the lips tends to be a more viscous liquid than lip gloss applied using fingertips. Naturally, roll-on lip gloss is considered to have a higher oil content and a higher amount of solids or wax than fingertip lip gloss. Such hydrophobic components in cosmetic stains may be natural and / or synthetic, and include, for example, waxes, canola oil, cetyl alcohol, cetyl esters, cocoa (Theobroma cacao) butter, coconut (Cocos nucifera) oil, hydrolyzed beeswax, lanolin oil, lanolin wax, mineral oil, paraffin, PEG beeswax, petrolatum, petroleum jelly, shea butter, and many others. Additional materials found in cosmetics include, for example, silicones such as dimethicone, other silicone-based materials such as amodimethicone, and other pigments, dyes, colorants, and fragrances. Cosmetic products may also contain various forms of sunscreens, such as titanium dioxide and zinc oxide, both of which often leave an undesirable white film after stain removal.

[0108] It is understood that the detergents and cleaning compositions disclosed herein can remove cosmetic stains having the hydrophobic materials and other materials described above, as well as exemplary stains not included in the above list. In one embodiment, the hydrophobic stain is an oil, a viscous solid, a silicone, a wax, a pigment, or a combination thereof.

[0109] A cleaning method involves contacting a surface from which such dirt needs to be removed. In one embodiment, the surface is a hard surface soiled with waxy, oily, and / or greasy cosmetic stains. The surface can be brought into contact with the detergent and cleaning composition using any contact means, including, for example, immersion, spraying, dripping, and wiping. The surface can also be immersed in the detergent and cleaning composition (or individual parts thereof), including pretreatment, so as to fall within the scope of contact as described herein. As a result of the contact step, the surface is cleaned and the dirt is removed.

[0110] In certain embodiments, a concentrate may be sprayed onto a surface for hard surface treatment. Contact time may vary from a few seconds to several minutes. In other embodiments, lower concentrations of detergents and cleaning compositions may be used in pre-soaking applications, such as immersing the surface before further cleaning (e.g., mechanical action and / or force applied in a cleaning operation). In such embodiments, contact time may vary from several minutes to several hours (e.g., overnight immersion).

[0111] In one embodiment, the surface is a hard surface. In a further embodiment, the surface is a hard surface having one or more hydrophobic and / or oily stains, such as cosmetic stains. An exemplary surface is a cosmetic manufacturing apparatus, as found in industrial applications. Those skilled in the art will see that such hard surfaces can be metal (e.g., stainless steel, aluminum), concrete, glass, ceramic, and / or plastic surfaces. Due to the neutral pH of the detergents and cleaning compositions, the compositions described herein are beneficially safe for soft metals.

[0112] In another embodiment, the surface is a soft surface. In a further embodiment, the surface is a soft surface having one or more hydrophobic and / or oily stains, such as cosmetic stains. Examples of soft surfaces include objects and / or linens such as towels, sheets, and nonwoven webs. In one embodiment, the washing process is suitable for use in laundry applications adapted to maintain an insoluble solvent in the emulsion and not separate from water, especially at high temperatures. In an exemplary washing method, ensuring that the insoluble solvent does not separate from water may include mixing or stirring in a conventional machine washing process, for example.

[0113] The cleaning steps described herein may constitute part of a manual cleaning process involving mixing or stirring to ensure that the insoluble solvent does not separate from the water. In other embodiments, the utensils are cleaned by an automated method and / or by mechanical force or action applied after the detergent and cleaning composition has come into contact with the surface, or in combination. Examples of mechanical action and / or force include, for example, application using a spray nozzle, movement in a mixing tank, or manual and / or mechanical scrubbing. In some embodiments, stirring is used to aid in the removal of dirt. However, in other applications, stirring, whether mechanical or by other means, is not required to remove dirt, providing a significant advantage over state-of-the-art cleaning methods. Due to the neutral pH of the detergent and cleaning composition, the compositions described herein are beneficially low-foaming and safer than commercially available detergents.

[0114] In cleaning, immersion (or pretreatment) and / or other hard surface treatment applications, detergents and cleaning compositions can be applied to surfaces alone or in combination with additional builder compositions and / or additional booster compositions (i.e., cleaning systems). In some embodiments, detergents and cleaning compositions may be used only in immersion applications so as not to require mechanical action and / or force to remove dirt. Instead, immersion in an aqueous cleaning solution, followed by rinsing, is suitable for removing dirt according to the methods described herein.

[0115] Detergents and cleaning compositions may be applied in concentrates and / or working solutions. In embodiments in which a concentrated composition is applied, a first step of diluting and / or producing an aqueous working solution may also be included in the method. An exemplary dilution step includes bringing a liquid composition into contact with water.

[0116] Detergents and cleaning compositions may be provided in ready-to-use and / or concentrated compositions at the level of active ingredients, providing the desired amount of active ingredients in the composition, i.e., the surfactant of the detergent composition. In one embodiment, a suitable concentration of the detergent and cleaning composition is applied to a surface at a concentration of about 0.5% to about 20%, about 1% to about 10%, or about 1% to about 6% in the solution.

[0117] In one embodiment, the detergent and cleaning composition are applied to a surface. In embodiments where the detergent and cleaning composition are applied to a surface requiring cleaning, the solution used has a pH of about 6 to about 9, or preferably about 6.5 to about 7.5.

[0118] In one embodiment, the detergent and cleaning composition come into contact with the surface at any preferred temperature. In one embodiment, the temperature is approximately ambient temperature (generally 50° to 60°F) to about 200°F, about 20°F to about 180°F, about 30°F to about 160°F, about 40°F to about 140°F, about 50°F to about 120°F, about 60°F to about 100°F, about 70°F to about 90°F, or about 70°F to about 80°F. Beneficially, according to the embodiment of use, the detergent and cleaning composition are low-foaming even at low temperatures, enabling use over a wide range of temperatures. This differs from conventional detergents that are low-foaming at high temperatures but have a much higher foaming level at low temperatures.

[0119] In one embodiment, the detergent and cleaning composition are in contact with the surface for a sufficient time to remove the dirt, encompassing a range from a few seconds to several hours. In one embodiment, the detergent and cleaning composition are in contact with the surface for at least about 15 seconds, at least about 30 seconds, at least about 45 seconds, or at least about 60 seconds. In an additional embodiment, the detergent and cleaning composition are in contact with the surface for at least about 1 minute, at least about 2 minutes, at least about 3 minutes, at least about 4 minutes, or at least about 5 minutes. In yet another embodiment, the detergent and cleaning composition are in contact with the surface for at least about 15 minutes, at least about 30 minutes, at least about 60 minutes, at least about 2 hours, or longer.

[0120] In one embodiment, the detergent and cleaning composition may further include, or exclude, the use of mechanical force to help remove dirt.

[0144] Examples

[0145] Embodiments of the present disclosure are further defined in the following non-limiting embodiments. These embodiments illustrate certain embodiments of the present disclosure, but should be understood to be given merely as examples. From the above considerations and these embodiments, those skilled in the art can identify the essential features of the present disclosure and make various changes and modifications to the embodiments of the present disclosure to suit various uses and conditions without departing from the spirit and scope thereof. Accordingly, various modifications to the embodiments of the present disclosure will be apparent to those skilled in the art from the foregoing description, in addition to those shown and described herein. Such modifications are also intended to be included within the scope of the appended claims.

[0146] The following materials were used in the examples to evaluate various insoluble solvents and surfactant systems for cleaning hydrophobic stains, including various types of shower and hair care, oral care, deodorant, face and body care, lip gloss, lipstick, mascara, foundation, and sunscreen stains.

[0147] Purasolv EHL (L-2-ethylhexyl lactate insoluble solvent), commercially available from Corbion.

[0148] Glucopon 600 UP (lauryl / myristyl glucoside surfactant), commercially available from BASF.

[0149] Tomamine Amphoteric 400 (sodium octyliminodipropionate surfactant), commercially available from Evonik.

[0150] Tomamine Amphoteric 12 (a monosodium alkyliminodipropionate surfactant) is commercially available from Evonik.

[0151] Trilon M, Liquid Neut. (Methylglycine diacetate (MGDA) trisodium), commercially available from BASF.

[0152] Purasolv EL (ethyl lactate cosolvent), commercially available from Corbion.

[0153] Example 1 The stain-removing effects of various solvents in the detergents and cleaning compositions described herein on lipstick stains on stainless steel specimens (SS318, 2 x 3 inch specimens, vertical grain) were evaluated by performing a cleaning method on soiled specimens. Stain: Maybelline lipstick. The stain was spread evenly on the specimen with a foam brush or applied using the application device provided with the product. The specimens were dried overnight at room temperature. The following day, the soiled specimens were weighed on a chemical balance and the data recorded. The soiled specimens were then placed in stirred beakers for cleaning with various combinations of the detergent compositions and / or builder compositions.

[0154] Soiled test specimens were immersed for 30 minutes at 140°F (60°C) in various detergents and cleaning compositions at approximately 4% concentrations, as listed in Table 2, according to the solvent in the formulation, under stirring.

[0155] The soiled test specimens were visually observed every 5 minutes for a visual evaluation of stain removal, and a visual rating from 1 to 5 was given (1 = no stain removal, 5 = complete stain removal). Exemplary visual scores are shown in Figure 1. All observations of the soiled test specimens were averaged to obtain normalized results for cleaning performance. The obtained visual ratings for the evaluated composition solutions containing different solvents on lipstick stains are shown in Table 2.

[0156] [Table 2]

[0157] Similarly, Figure 2 shows the LogP and topological polarity surface area values ​​of the solvents corresponding to the visual rankings found in Table 2. The LogP and topological polarity surface area values ​​were obtained from PubChem.

[0158] These results in Figure 2 indicate that the best stain removal results, with a visual evaluation score greater than 1, are associated with LogP ≥ 2 and a topological polar surface area (A) of approximately 20-50. 2 This shows that the solvent has a topological polarity (A) between approximately 15 and 50. 2 While providing the same benefits, they have different chemical structures and classifications. The limited effect of water polarity is further demonstrated by the fact that, lacking polar functional groups, it does not exhibit the same effectiveness as solvents that are solely carbon (i.e., toluene).

[0159] Example 2 The cleaning method for soiled test specimens of Example 1 was performed to evaluate the stain-removing effects of the experimental detergent compositions described herein and three commercially available detergent compositions on 12 different cosmetic stains on stainless steel test specimens. Each stain—shower and hair care, oral care, deodorant, face and body care, lip gloss, lipstick, mascara, foundation, and sunscreen—was spread evenly on the test specimen with a foam brush. The test specimens were dried overnight and placed in a stirring beaker for cleaning with various combinations of detergent compositions and / or builder compositions.

[0160] A 400 mL beaker was filled with 300 mL of cleaning solution, heated to 140°F and stirred at 250 rpm, to a total concentration of 4%. The soiled test specimens were immersed for 30 minutes under stirring. After washing, the test specimens were weighed again to determine the weight percentage of the dirt lost, and the cleaning efficiency was calculated based on the percentage of the weight of the dirt removed. The detergents and cleaning compositions evaluated were formulated according to Table 3 below. The commercially available detergent compositions evaluated are summarized in Tables 4-6, along with explanations from the safety data sheets, but in particular, the compositions do not contain insoluble solvents as described herein.

[0161] [Table 3]

[0162] [Table 4]

[0163] [Table 5]

[0164] [Table 6]

[0165] The soiled test pieces were visually observed every 5 minutes for a visual evaluation of stain removal, and a visual rating from 1 to 5 was given (1 = no stain removal, 5 = complete stain removal). The obtained visual evaluation results for the cleaning solutions against 12 types of cosmetic stains are shown in Figure 3. The average rating of the evaluated composition of formulation A was 3.81 across all cosmetic stains, showing improved stain removal performance compared to commercially available control detergent compositions, as summarized in Table 7.

[0166] [Table 7]

[0167] As shown in Figure 3 and Table 7, formulation A exhibits improved effectiveness compared to commercially available detergents in removing conventionally insoluble dirt, as a result of the insoluble solvent that aids in the removal of these dirt. Although not limited to a specific mechanism of action, the insoluble solvent assists in the dissolution of dirt, i.e., oily and hydrophobic parts, in addition to the cleaning mechanisms associated with conventional aqueous detergents (i.e., emulsification, dirt suspension, chelation, etc.).

[0168] Example 3 Using the cleaning methods for soiled test specimens described in Examples 1 and 2, the stain-removing effects of various combinations of the experimental detergent compositions and seven commercially available detergents described herein on lipstick stains on stainless steel test specimens were evaluated. Lipstick stains were experimental formulations known to be difficult to clean. The lipstick was spread evenly on the test specimen, dried overnight, and then immersed in the cleaning solution. The concentrations of the detergents and cleaning compositions evaluated were measured individually and with surfactants at both 2% and 5% of the total composition (the solution used), as listed in Tables 3 to 6, at 140 o F, 160 o F and 180 o The samples were evaluated at F for 10, 30, and 60 minutes, and the results are shown in Table 8. Commercial products 1-3 are the same commercial detergents as those described in Example 2 and Tables 4-6. Commercial product 4 is a liquid oxygen (oxidizing) cleaning additive used with alkaline and acidic set-in cleaning detergents, containing hydrogen peroxide, C12-C18 alcohols, and polyethylene glycol. Commercial product 5 is a neutral cleaning additive used with alkaline and acidic set-in cleaning detergents for organic stains such as grease, containing alkylamine ethoxylates, C12-C18 alcohols, and polyethylene glycol. Commercial product 6 is an acidic cleaning cleaner containing nitric acid and phosphoric acid. Commercial product 7 is an alkaline cleaning detergent cleaner containing sodium hydroxide. The commercial products described herein do not contain the insoluble solvents contained in formulation A.

[0169] [Table 8]

[0170] To illustrate the results summarized in Table 8, visual results before and after cleaning are shown in Figure 4. These results demonstrate that Formulation A, as described herein, is superior to commercially available products in cleaning performance, based on a summary of the observed cleaning results.

[0171] Example 4 Commercially available products were generally compared to experimental formulation A based on cleaning effectiveness, pH, safety, and other factors. The commercial products were the same as those used in Examples 2 and 3 (commercial products #1-3), and commercial product #8 was a commercially available alkaline detergent. All commercial products were highly alkaline with a pH of approximately 11-12, while experimental formulation A was nearly neutral with a pH of approximately 7. Due to the pH level of the experimental formulation, it is safe for soft metals, reduces costs by eliminating the need to adjust the pH during wastewater treatment, and has a lower safety risk. Furthermore, the experimental formulation is readily biodegradable and has an extremely low foaming level, which reduces rinsing time and water consumption after cleaning, especially for highly foaming stains such as shampoo, conditioner, and toothpaste, and can reduce the amount of defoamer needed during wastewater treatment. Therefore, the experimental formulation not only has superior cleaning performance compared to commercial products, but also offers additional cost savings and risk benefits that surpass commercial products.
