Description

[0001] The present invention relates to fabric sprays that renew clothes. Background of the Invention

[0002] Consumers have increasingly busy lives, with limited time to wash their clothes. On the other hand, approximately 40% of the clothes that go through the washing process are not dirty and could be worn again. This practice of over-washing leads to unnecessary water consumption, which can be problematic, particularly in water-scarce regions of the world.

[0003] Several fabric renewal sprays have been revealed previously. Such sprays commonly contain perfumes and / or anti-wrinkle ingredients. However, there remains a need for superior products that give consumers the confidence to wear their clothes again.

[0004] A particular unmet need is for a product that reduces bad odors. Another consideration is that consumers tend towards 'green' products that contain ingredients that are better for the planet, for example, more biodegradable, of natural origin or renewable origin. It has been surprisingly evaluated that the compositions of the present invention provide effective control of bad odor. Summary of the Invention

[0034] The logP values ​​of various perfume ingredients have been reported; for example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc. (Daylight CIS), Irvine, California, contains several, in addition to citations to the original literature. However, logP values ​​are more conveniently calculated by the CLOGP program, also available from Daylight CIS. This program also lists experimental logP values ​​when available in the Pomona92 database. The calculated logP (ClogP) is determined by the fragmental approach of Hansch and Leo (as per A. Leo, in Comprehensive Medicinal Chemistry, vol. 4, C. Hansch, P.G. Sammens, J.B. Taylor, and C.A. Ramsden, Eds., p. 295, Pergamon Press, 1990, incorporated herein by reference). The fragmental approach is based on the chemical structure of each perfume ingredient and takes into account the number and types of atoms, the connectivity of the atoms, and chemical bonding.The ClogP values ​​are the most reliable and widely used estimates for this physical property. Petition 870220047628, dated 05 / 31 / 2022, page 15 / 55 10 / 35 chemical values ​​are used instead of experimental logP values ​​in the selection of perfume ingredients here.

Anti-odor agent

[0079] Spray compositions of the present invention preferably comprise an anti-odor agent. Anti-odor agents enhance the odor-fighting effects of the compositions described herein. In the context of the present invention, free perfumes are not considered anti-odor agents.

[0080] Anti-odor agents may be present at a selected level of: less than 20%, less than 10% and less than 5% by weight of the spray composition. Suitablely, the anti-odor agent is present in the spray composition in a selected amount in the range of about 0.01% to about 5%, preferably from about 0.1% to about 3%, more preferably from about 0.5% to about 2% by weight of the spray composition.

[0081] Any suitable odor-controlling agent may be used. In fact, an odor-controlling effect may be achieved by any compound or product that is effective in trapping, absorbing or destroying odor molecules in order to then separate or remove odor from clothing or act as an odor counteragent.

[0082] The odor control agent may be selected from the group consisting of: non-complexed cyclodextrins; odor blockers; reactive aldehydes; Petition 870220047628, dated 05 / 31 / 2022, page 25 / 55 20 / 35 flavonoids; zeolites; activated charcoal; a mixture of zinc ricinoleate or a solution thereof and a substituted monocyclic organic compound; prebiotics and mixtures thereof.

[0083] A particularly preferred anti-odor agent is a prebiotic. Prebiotics are substances that selectively stimulate the growth and / or activity of one or more microorganisms. In the context of the present invention, prebiotics prevent bad odors from developing in used clothing, i.e., after the clothing has been worn for a day, applying a prebiotic of a spray composition significantly reduces the development of bad odors.

[0084] Preferred prebiotics for use in the present invention comprise at least one saccharide unit selected from: galactose, galacturonic acid, mannuronic acid, guluronic acid, glucan, glucose and combinations thereof. More preferably the prebiotic comprises at least one saccharide unit selected from: galactose, galacturonic acid, mannuronic acid, guluronic acid, glucan and combinations thereof. Even more preferably the prebiotic comprises at least one saccharide unit selected from: galactose, galacturonic acid and guluronic acid.

[0085] Examples of suitable prebiotics include: pectin (polymer of galacturonic acid), lactitol (4-OaD-galactopyranosyl-D-glucitol), algin (a homopolymer of β-D-mannuronate (1-4)-linked and its α-L-guluronate).

[0086] A suitable odor-controlling agent is cyclodextrin, suitably, water-soluble, non-complexed cyclodextrin. Suitably, cyclodextrin is present at a selected level of 0.01% to 5%, 0.1% to 4% and 0.5% to 2% by weight of the spray composition.

[0087] In the context of the present invention, the term cyclodextrin includes any of the cyclodextrins known as unsubstituted cyclodextrins containing six to twelve glucose units, especially alpha-cyclodextrin, beta-cyclodextrin, gamma-cyclodextrin and / or their derivatives and / or mixtures thereof. Alpha-cyclodextrin consists of six glucose units, beta Petition 870220047628, dated 05 / 31 / 2022, p. 26 / 55 21 / 35 cyclodextrin consists of seven glucose units, and gamma-cyclodextrin consists of eight glucose units arranged in donut-shaped rings.

[0088] Preferably, cyclodextrins are highly soluble in water, such as alpha-cyclodextrin and / or derivatives thereof, gamma-cyclodextrin and / or derivatives thereof, beta-cyclodextrin derivatives, and / or mixtures thereof. Cyclodextrin derivatives consist mainly of molecules in which some of the OH groups are converted to OR groups. Cyclodextrin derivatives include, e.g., those with short-chain alkyl groups such as methylated cyclodextrins and ethylated cyclodextrins, wherein R is a methyl or ethyl group; those with substituted hydroxyalkyl groups, such as hydroxypropyl cyclodextrin and / or hydroxyethyl cyclodextrins, wherein R is a -CH2-CH(OH)-CH3 or a -CH2CH2-OH group; branched cyclodextrins such as maltose-linked cyclodextrins; Cationic cyclodextrins such as those containing 2-hydroxy-3-(dimethylamino)propyl ether, where R is CH2-CH(OH)-CH2-N(CH3)2, which is cationic at low pH; quaternary ammonium, e.g., chloride groups of 2-hydroxy-3-(trimethylammonium)propyl ether, wherein R is CH2-CH(OH)-CH2-N+(CH3)3Cl-; anionic cyclodextrins such as carboxymethyl cyclodextrins, cyclodextrin sulfates, and cyclodextrin succinylates; amphoteric cyclodextrins such as carboxymethyl / quaternary ammonium cyclodextrins; cyclodextrins in which at least one glucopyranose unit has a 3-6-anhydrocyclomalto structure, e.g. mono-3-6-anhydrocyclodextrins.

[0089] Highly water-soluble cyclodextrins are those having a water solubility of at least about 10g in 100mL of water at room temperature, preferably at least about 20g in 100mL of water, more preferably at least about 25g in 100mL of water at room temperature. The availability of solubilized non-complexed cyclodextrins is essential for effective and efficient odor control performance. Solubilized water-soluble cyclodextrin may exhibit more efficient odor control performance than non-water-soluble cyclodextrin when deposited on surfaces, especially fabric. Petition 870220047628, dated 05 / 31 / 2022, page 27 / 55 22 / 35

[0090] Examples of water-soluble cyclodextrin derivatives preferred for use as described herein are hydroxypropyl alpha-cyclodextrin, methylated alpha-cyclodextrin, methylated beta-cyclodextrin, hydroxyethyl beta-cyclodextrin, and hydroxypropyl beta-cyclodextrin. Hydroxyalkyl cyclodextrin derivatives preferably have a degree of substitution of about 1 to about 14, more preferably of about 1.5 to about 7, wherein the total number of OR groups per cyclodextrin is defined as the degree of substitution. Methylated cyclodextrin derivatives typically have a degree of substitution of about 1 to about 18, preferably about 3 to about 16. A known methylated beta-cyclodextrin is heptakis-2,6-di-O-methyl-e-cyclodextrin, commonly known as DIMEB, in which each glucose unit has about 2 methyl groups with a degree of substitution of about 14.A more commercially available, preferred methylated beta-cyclodextrin is a randomly methylated beta-cyclodextrin, commonly known as RAMEB, having varying degrees of substitution, typically around 12.6%. RAMEB is preferred over DIMEB because DIMEB affects the surface activity of preferred surfactants more than RAMEB. Preferred cyclodextrins are available, e.g., from Cerestar USA, Inc. and Wacker Chemicals (USA), Inc.

[0091] In the applications, mixtures of cyclodextrins are used.

[0092] Odor blockers can be used as an anti-odor agent to mitigate the effects of bad odors.

This combination of at least two aldehydes is described in more detail in WO 00 / 49120. In the context of the present invention, the term reactive aldehyde further encompasses deodorizing materials that are the reaction products of (i) an aldehyde with an alcohol, (ii) a ketone with an alcohol, or (iii) a... Petition 870220047628, dated 05 / 31 / 2022, p. 29 / 55 24 / 35 aldehyde with the same or different aldehydes. Such deodorizing materials may be: (a) an acetal or hemiacetal produced by reacting an aldehyde with a carbinol; (b) a ketal or hemiketal produced by reacting a ketone with a carbinol; (c) a cyclic triacetal or a cyclic triacetal mixture of at least two aldehydes, or a mixture of any of these acetals, hemiacetals, ketals, hemiketals or cyclic triacetals. These perfume deodorizing materials are described in greater detail in WO 01 / 07095 incorporated herein by reference.

[0094] Flavonoids can also be used as an anti-odor agent. Flavonoids are compounds based on the C6-C3-C6 flavan skeleton. Flavonoids can be found in typical essential oils. Such oils include essential oils extracted by dry distillation from slender-leaved trees and grasses such as cedar, Japanese cypress, eucalyptus, Japanese red pine, dandelion, low-leaved bamboo, and geranium, and may contain terpene material such as alpha-pinene, beta-pinene, myrcene, fencone, and camphene. Tea leaf extracts are also included. Descriptions of such materials can be found in JP 02284997 and JP 04030855 incorporated herein by reference.

[0095] Metallic salts can also be used as anti-odor agents for the benefit of controlling bad odor. Examples include metallic salts of fatty acids. Ricinoleic acid is a preferred fatty acid. Zinc salt is a preferred metallic salt. The zinc salt of ricinoleic acid is especially preferred.One commercially available product is Evonik's TEGO Sorb A30. Further details on suitable metal salts are provided below.

[0096] Zeolites can be used as an anti-odor agent. A useful class of zeolites is characterized as intermediate silicate / aluminate zeolites. Intermediate zeolites are characterized by SO2 / AO2 molar ratios of less than about 10. Preferably, the SO2 / AO2 molar ratio is in the range of about 2 to about 10. Intermediate zeolites may have an advantage over superior zeolites. Intermediate zeolites have a greater affinity for amine-type odors; they are more efficient by weight for Petition 870220047628, dated 05 / 31 / 2022, page 30 / 55 25 / 35 odor absorption because they have a larger surface area, and they are more moisture-tolerant and retain more of their odor-absorbing capacity in water than superior zeolites. A wide variety of intermediate zeolites suitable for use here are commercially available such as Valfor® CP301-68, Valfor® 300-63, Valfor® CP300-35 and Valfor® CP300-56, made available by PQ Corporation, and the CBV100® series of zeolites from Conteka. Zeolite materials marketed under the names Abscents® and Smellrite®, made available by The Union Carbide Corporation and UOP, are also preferred. Such materials are preferred over intermediate zeolites for odor control containing sulfur, e.g., thiols, mercaptans. Appropriately, the zeolite material has a particle size smaller than about 10 micrometers and is present in the spray composition at a level of less than about 1% by weight of the spray composition.

[0097] Activated carbon is another suitable odor-control agent. Suitable carbon material is a known absorbent for organic molecules and / or for air purification purposes. Frequently, such carbon material is referred to as activated carbon or activated charcoal. Such carbon is available from commercial sources under the names Calgon-Type CPG®; Type PCB®, Type SGL®, Type CAL® and Type OL®. Suitablely, the activated carbon preferably has a particle size smaller than about 10 micrometers and is present in the spray composition at a level of less than about 1% by weight of the spray composition.

[0105] For the scope, any material described herein as an odor control agent may also be classified as another component described herein; for the purpose of the present invention, such material is classified as an odor control agent. pH

[0106] The pH of the spray compositions of the present invention is preferably 2-12. Other ingredients

[0107] Other optional ingredients may be present in the aqueous spray composition of the present invention. For example, the aqueous spray compositions may additionally comprise: colorants / toners, preservatives, viscosity control agents, microcapsules comprising beneficial agents, structuring / dispersing agents, solvents, antifoaming agents to aid in processing, etc. Spray bottle

[0108] The compositions are fabric spray compositions. Therefore, it should be understood that the compositions are suitable for spraying onto a fabric. They can be sprayed by any suitable spray device.

[0109] Preferably, the spray device is a manually operable spray device in the sense that the spray mechanism is manually operable to discharge a dose of said composition from the nozzle.

[0110] The spray mechanism may be operated by an actuator. The actuator may be a push actuator or a pull actuator. The actuator may comprise a trigger. The spray mechanism may comprise a Petition 870220047628, dated 05 / 31 / 2022, page 35 / 55 30 / 35 hand-operated pump. Optionally, said pump is one of: a positive displacement pump; a self-priming pump; a reciprocating pump. Suitable spray devices include trigger sprays, continuous / semi-continuous sprays, finger-pump sprays, sprays with vibrating sieve output.

[0111] Preferably, the spray device is operable without the use of a propellant. Certainly, propellant-free spray devices are preferred. This allows the spray to maintain the integrity and purity of the product, not contaminated with propellant, and is preferably environmentally friendly.

[0112] Preferably the spray device is pressurized. This can improve spray duration and speed. Preferably, the spray device is pressurized by a gas chamber, separate from a reservoir containing the composition. The gas is preferably air or nitrogen. The spray device may comprise an outer container containing the composition and a pressurizing agent, wherein the composition is separated from the pressurizing agent by containment (preferably hermetically sealed) in a flexible bag. This maintains the complete integrity of the formulation so that only a pure composition (i.e., without pressurizing agent) is released. Preferred systems are so-called 'bag-in-can' (or BOV, bag-over-valve technology). Alternatively, the spray device may comprise a piston barrier mechanism, for example EarthSafe from Crown Holdings.

[0113] Preferably, the spray device comprises a biodegradable plastic material. The spray mechanism may further comprise an atomizer configured to fragment said liquid dose into droplets and thereby facilitate the creation of said fine aerosol in the form of a mist. Conveniently, said atomizer may comprise at least one of: a swirl chamber and a side dispersion chamber. Suitably, the atomizer functions to mix air with the aqueous tissue spray composition.

[0114] The particle size of the formulation when applied as a spray is Petition 870220047628, dated 05 / 31 / 2022, page 36 / 55 31 / 35 preferably no more than 300 µm, preferably no more than 250 µm, preferably no more than 150 µm, preferably no more than 125 µm, preferably no more than 100 µm. The particle size of the formulation when applied as a spray is preferably at least 5 µm, preferably at least 10 µm, preferably at least 15 µm, preferably at least 20 µm, preferably at least 30 µm, preferably at least 40 µm. Suitably, the spray comprises droplets having an average diameter in the range of preferably 5 to 300 µm, more preferably 10 to 250 µm, even more preferably 15 to 150 µm. This size allows for homogeneous distribution and a balance between sufficiently wetting the fabric without potential damage to the fabric caused by overdosing of certain ingredients. The droplet size can be measured using a Malvern Spraytec instrument, with a peak maximum corresponding to the average droplet size.The parameter particle size is the volume average diameter, D[4,3].

[0115] Ideally, after activation, the spray has a duration of at least 0.4 seconds. Preferably, the spray has a duration of at least 0.8 seconds. A longer duration minimizes effort by maximizing coverage per activation of the spray device. This is an important factor for products designed to be applied over the entire area of ​​clothing. Preferably, the spray duration is directly linked to the activation so that the spray output continues only while the activator is engaged (e.g., while a button or trigger is pressed).

[0116] Spray reservoirs can be non-pressurized devices, manually or mechanically pre-pressurized. The above also applies to removable / refillable reservoirs.

[0117] According to a further aspect of the present invention, a replacement reservoir is provided for a spray product according to the aspect(s) above, the replacement reservoir being filled with a volume of said spray composition for replenishing said product. A suitable refill kit comprises one or more reservoirs. Petition 870220047628, dated 05 / 31 / 2022, page 37 / 55 32 / 35 In the case of more than one reservoir, for example two, three, four, five or more reservoirs, the contents (aqueous fabric spray composition) of each reservoir may be the same or different from the other reservoirs. Dose

[0118] Conveniently, the spray composition is supplied as a liquid, and said spray mechanism is operable to discharge a dose of at least 0.1 mL, preferably at least 0.2 mL, more preferably at least 0.25 mL, more preferably at least 0.3 mL, more preferably at least 0.35 mL, more preferably at least 0.4 mL, more preferably at least 0.45 mL and even more preferably at least 0.5 mL.

[0119] Appropriately, the dose is no more than 2 mL, preferably no more than 1.8 mL, preferably no more than 1.6 mL, more preferably no more than 1.5 mL, more preferably no more than 1.4 mL, more preferably no more than 1.3 mL and even more preferably no more than 1.2 mL.

[0126] Hydrogen sulfide gas is produced by bacteria when given any source of sulfur, either L-cysteine ​​hydrochloride or L-cysteine ​​dihydrochloride. Hydrogen sulfide production can be measured using lead acetate paper, which darkens upon reaction with hydrogen sulfide to produce lead sulfide. The color change can be quantified using L*a*b* values ​​measured by a spectrometer.

[0127] Four volunteers wore sari blouses for 12 hours. The armpit area of ​​each blouse was cut into pieces, one was not treated and the other was sprayed once with composition 1. The pieces were then placed in wells with growth medium (tryptic soy casein broth with 0.2% L-cysteine ​​hydrochloride). Lead acetate paper was placed above the wells attached to the inner base of the lid. After 24 hours, the lead acetate paper was removed and the L*a*b* values ​​were measured. Delta E was then calculated for each lead acetate paper test sample by comparing the measured L*a*b* values ​​with the L*a*b* values ​​of the unused lead acetate paper (control), using Equation 1: Ail = i(h-L')2+(a2-a,)2(Eq. 1)

[0128] Where:

[0129] L*2, a*2 and b*2 are the values ​​for test lead acetate paper

[0130] L*1, a*1 and b*1 are the values ​​for control lead acetate paper Petition 870220047628, dated 05 / 31 / 2022, pages 40 / 55 35 / 35 Table 2 Untreated Composition 1 Delta E values ​​from a blank control 39 24

[0131] A lower delta E means that the lead acetate paper was clearer, which means that it reacted with less hydrogen sulfide, indicating a lower level of bad odors.
