Description

Field of the Invention

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

[0003] Consumers are living increasingly busy lives, leaving them with limited time for laundry. On the other hand, approximately 40% of laundry is not soiled and can be worn again. This excessive washing practice results in unnecessary water use, which can be problematic, particularly in water-scarce regions of the world.

[0004] Various fabric freshening sprays have been previously disclosed. Such sprays typically contain fragrances and / or anti-wrinkle ingredients. However, there remains a need for superior products that give consumers the confidence to wear garments repeatedly. One particular unmet need is for products that reduce odor. Another consideration is the consumer trend toward "green" products that contain ingredients that are better for the planet, e.g., more biodegradable, naturally derived, or from renewable resources. It has been surprisingly discovered that the compositions of the present invention provide effective odor control. SUMMARY OF THE INVENTION

[0058] The logP values of many fragrance ingredients have been reported; for example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc. (Daylight CIS), Irvine, Calif., contains many, along with references to the original literature. However, logP values are most conveniently calculated using the "CLOGP" program, also available from Daylight CIS. This program also lists experimental logP values available in the Pomona92 database. "Calculated logP" (ClogP) is determined by the fragment method of Hansch and Leo (see A. Leo, 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 fragment method is based on the chemical structure of each fragrance ingredient and takes into account the number and type of atoms, atomic connectivity, and chemical bonds. ClogP values, which are the most reliable and widely used estimate of this physicochemical property, were used in the selection of fragrance ingredients herein rather than experimental logP values.

[0059] It is common for multiple fragrance ingredients to be present in free oil fragrance compositions. In the compositions used in the present invention, it is envisioned that three or more, preferably four or more, more preferably five or more, and most preferably six or more different fragrance components will be present.

[0109] The iodine value of the quaternary ammonium fabric conditioning material is preferably from 0 to 80, more preferably from 0 to 60, and most preferably from 0 to 45. The iodine value can be selected appropriately. Substantially saturated materials having an iodine value of 0 to 5, preferably 0 to 1, can be used in the compositions of the present invention. Such materials are referred to as "hardened" quaternary ammonium complexes.

[0110] A further preferred range for the iodine value is from 20 to 60, preferably from 25 to 50, more preferably from 30 to 45. Materials of this type are "soft" triethanolamine quaternary ammonium compounds, preferably triethanolamine dialkyl ester methyl sulfate. Such ester-linked triethanolamine quaternary ammonium compounds contain unsaturated fatty chains. If a mixture of quaternary ammonium materials is present in the composition, the iodine value above represents the average iodine value of the parent fatty acyl compounds or fatty acids of all quaternary ammonium materials present. Similarly, if any saturated quaternary ammonium materials are present in the composition, the iodine value represents the average iodine value of the fatty acid parent acyl compounds of all quaternary ammonium materials present.

[0111] Iodine value as used in the context of the present invention refers to the fatty acids used to generate the QAC, with the degree of unsaturation present in the material measured by nmr spectroscopy as described in Anal. Chem., 34, 1136 (1962) Johnson and Shoolery.

[0115] Anti-odor agent

[0116] The spray composition of the present invention preferably comprises an anti-odor agent. Anti-odor agents enhance the deodorizing effect of the composition described herein. In the context of the present invention, free fragrance is not considered an anti-odor agent.

[0117] The anti-odor agent may be present at a level selected from the following: less than 20%, less than 10% and less than 5% by weight of the spray composition. The anti-odor agent is suitably present in the spray composition in an amount selected from the range of about 0.01% to about 5%, preferably about 0.1% to about 3%, more preferably about 0.5% to about 2% by weight of the spray composition.

[0118] Any suitable anti-odor agent may be used. In fact, the anti-odor effect may be achieved by any compound or product that effectively "captures," "absorbs," or "destroys" odor molecules, thereby separating or removing odor from clothing or acting as a "malodour counteractant."

[0119] The odor controlling agent is preferably selected from the group consisting of uncomplexed cyclodextrins, odor blockers, reactive aldehydes, flavonoids, zeolites, activated carbon, mixtures of zinc ricinoleate or solutions thereof, substituted monocyclic organic compounds, prebiotics, and mixtures thereof.

[0120] Particularly preferred anti-odor agents are prebiotics. 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 the development of odor on worn clothing, i.e., after the clothing has been worn for a day, the application of prebiotics from the spray composition significantly reduces the development of odor.

[0121] Preferably, the prebiotic for use in the present invention comprises at least one saccharide unit selected from the group consisting of galactose, galacturonic acid, mannuronic acid, guluronic acid, dextran, glucose, and combinations thereof. More preferably, the prebiotic comprises at least one saccharide unit selected from the group consisting of galactose, galacturonic acid, mannuronic acid, guluronic acid, dextran, and combinations thereof. Most preferably, the prebiotic comprises at least one saccharide unit selected from the group consisting of galactose, galacturonic acid, and guluronic acid.

[0122] Examples of suitable prebiotics include: pectin (a galacturonic acid polymer), lactitol (4-O-α-D-galactopyranosyl-D-glucitol), algin (a homopolymer of (1-4)-linked β-D-mannuronate and its α-L-guluronate).

[0123] One suitable anti-odour agent is a cyclodextrin, suitably a water soluble uncomplexed cyclodextrin. Suitably, the cyclodextrin is present at a level selected from 0.01% to 5%, 0.1% to 4% and 0.5% to 2% by weight of the spray composition.

[0124] As used herein, the term "cyclodextrin" encompasses any known cyclodextrin, such as unsubstituted cyclodextrins containing six to twelve glucose units, in particular α-cyclodextrin, β-cyclodextrin, γ-cyclodextrin and / or their derivatives, and / or mixtures thereof. α-cyclodextrin consists of six glucose units, β-cyclodextrin consists of seven glucose units, and γ-cyclodextrin consists of eight glucose units arranged in a donut-shaped ring.

[0125] Preferably, the cyclodextrin is highly water-soluble, for example, α-cyclodextrin and / or its derivatives, γ-cyclodextrin and / or its derivatives, derivatized β-cyclodextrin and / or mixtures thereof. Derivatives of cyclodextrins mainly consist of molecules in which some of the OH groups are converted into OR groups. Cyclodextrin derivatives include, for example, those with short chain alkyl groups, such as methylated cyclodextrins and ethylated cyclodextrins, where R is methyl or ethyl; those with hydroxyalkyl substituents, such as hydroxypropyl cyclodextrin and / or hydroxyethyl cyclodextrin, where R is a -CH2-CH(OH)-CH3 or -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, for example, 2-hydroxy-3-(trimethylammonio)propyl ether chloride, where R is CH2-CH(OH)-CH2-N(CH3)2; + (CH3)3Cl - ; anionic cyclodextrins, such as carboxymethyl cyclodextrin, cyclodextrin sulfate and cyclodextrin succinate; amphoteric cyclodextrins, such as carboxymethyl / quaternary ammonium cyclodextrin; cyclodextrins in which at least one pyranose glucose unit has a 3-6-anhydro-cyclomaltose structure, such as mono-3-6-anhydrocyclodextrin.

[0126] Highly water-soluble cyclodextrins are those having a water solubility of at least about 10 g in 100 ml of water at room temperature, preferably at least about 20 g in 100 ml of water, and more preferably at least about 25 g in 100 ml of water at room temperature. The availability of dissolved, uncomplexed cyclodextrins is crucial for effective and efficient odor control performance. When deposited on surfaces, especially fabrics, dissolved, water-soluble cyclodextrins can exhibit more effective odor control performance than water-insoluble cyclodextrins.

[0127] Examples of preferred water-soluble cyclodextrin derivatives suitable for use herein are hydroxypropyl α-cyclodextrin, methylated α-cyclodextrin, methylated β-cyclodextrin, hydroxyethyl β-cyclodextrin, and hydroxypropyl β-cyclodextrin. Hydroxyalkyl cyclodextrin derivatives preferably have a degree of substitution of from about 1 to about 14, more preferably from about 1.5 to about 7, where the total number of OR groups per cyclodextrin defines the degree of substitution. Methylated cyclodextrin derivatives typically have a degree of substitution of from about 1 to about 18, preferably from about 3 to about 16. A known methylated β-cyclodextrin is heptakis-2,6-di-O-methyl-β-cyclodextrin, commonly known as DIMEB, in which each glucose unit has about 2 methyl groups and a degree of substitution of about 14. A preferred, more commercially available methylated β-cyclodextrin is randomly methylated β-cyclodextrin, commonly known as RAMEB, which has varying degrees of substitution, typically about 12.6. RAMEB is preferred over DIMEB because DIMEB affects the surface activity of the preferred surfactant more than RAMEB. Preferred cyclodextrins can be obtained, for example, from Cerestar USA, Inc. and Wacker Chemicals (USA), Inc.

[0128] In an embodiment, a mixture of cyclodextrins is used.

[0129] "Odor blockers" can be used as anti-odor agents to reduce the effects of odors.

U.S. Pat. Nos. 4,009,253, 4,187,251, 4,719,105, 5,441,727, and 5,861,371, which are incorporated herein by reference.

[0130] Reactive aldehydes can be used as anti-odor agents to reduce the effects of odor. Examples of suitable reactive aldehydes include Class I aldehydes and Class II aldehydes. Examples of Class I aldehydes include anisaldehyde, o-allyl-vanillin, benzaldehyde, cuminaldehyde, ethyl anisaldehyde, ethyl-vanillin, piperonal, tolualdehyde, and vanillin. Examples of Class II aldehydes include 3-(4'-tert-butylphenyl)propanal, 2-methyl-3-(4'-tert-butylphenyl)propanal, 2-methyl-3-(4'-isopropylphenyl)propanal, 2,2-dimethyl-3-(4-ethylphenyl)propanal, cinnamaldehyde, α-amyl-cinnamaldehyde, and α-hexyl-cinnamaldehyde. These reactive aldehydes are described in more detail in US5,676,163. When used, the reactive aldehyde may comprise a combination of at least two aldehydes, wherein one aldehyde is selected from acyclic aliphatic aldehydes, non-terpene aliphatic aldehydes, non-terpene alicyclic aldehydes, terpene aldehydes, aliphatic aldehydes substituted with aromatic groups, and difunctional aldehydes; and the second aldehyde is selected from aldehydes having unsaturation alpha to the aldehyde functional group conjugated to an aromatic ring, and aldehydes in which the aldehyde group is on an aromatic ring. Such combinations of at least two aldehydes are described in more detail in WO 00 / 49120. As used herein, the term "reactive aldehyde" further includes odor-eliminating materials that are the reaction products of (i) an aldehyde and an alcohol, (ii) a ketone and an alcohol, or (iii) an aldehyde and the same or different aldehyde. Such deodorizing materials may be: (a) acetals or hemiacetals produced by the reaction of an aldehyde with methanol; (b) ketals or hemiketals produced by the reaction of a ketone with methanol; (c) cyclic triacetals or mixed cyclic triacetals of at least two aldehydes, or any mixture of these acetals, hemiacetals, ketals, hemiketals or cyclic triacetals. These deodorizing fragrance materials are described in more detail in WO 01 / 07095, which is incorporated herein by reference.

[0131] Flavonoids can also be used as anti-odor agents. Flavonoids are compounds based on a C6-C3-C6 flavanoid skeleton. Flavonoids can be found in typical essential oils. These oils include essential oils extracted from conifers and grass plants (for example, cedar, Japanese cypress, eucalyptus, Japanese red pine, dandelion, low-striped bamboo and geranium) by dry distillation, and can contain terpene substances, for example, α-pinene, β-pinene, myrcene, phencone and camphene. Extracts from tea leaves are also included. Descriptions of such materials can be found in JP 02284997 and JP 04030855, which are incorporated herein by reference.

[0132] Metal salts can also be used as anti-odor agents for odor control benefits. Examples include metal salts of fatty acids. Ricinoleic acid is a preferred fatty acid. Zinc salts are preferred metal salts. Zinc salts of ricinoleic acid are particularly preferred. A commercially available product is TEGO Sorb A30 from Evonik.

Intermediate zeolites are characterized by a SiO2 / AlO2 molar ratio of less than about 10. Preferably, the SiO2 / AlO2 molar ratio ranges from about 2 to about 10. Intermediate zeolites can have advantages over "high" zeolites. Intermediate zeolites have a higher affinity for amine odors, they are more gravimetrically efficient at odor absorption due to their greater surface area, and they are more resistant to moisture and retain more odor absorption capacity in water than high zeolites. A variety of intermediate zeolites suitable for use herein can be used as CP301-68, 300-63, CP300-35 and CP300-56, which is commercially available from PQ Corporation, and The zeolites are available from Conteka under the trade names zeolites from The Union Carbide Corporation and UOP. and Commercially available zeolite materials are also preferred.

Suitably, the zeolite material has a particle size of less than about 10 microns and is present in the spray composition at a level of less than about 1% by weight of the spray composition.

[0134] Activated carbon is another suitable anti-odor agent. Suitable carbon materials are known adsorbents for organic molecules and / or for air purification purposes. Often, such carbon materials are referred to as "activated" carbon or "activated" charcoal. Type Type Type and Type Such carbon is obtained from commercial sources under such trade names as Activated Carbon.

For example, the aqueous spray composition may further comprise: colorants / dyes, preservatives, viscosity control agents, microcapsules containing beneficial agents, structuring agents / dispersants, solvents, defoaming agents for processing aids, etc.

[0173] spray bottle

[0174] The compositions are fabric spray compositions. This means that the compositions are suitable for spraying onto fabrics. They can be sprayed by any suitable spraying device.

[0175] Preferably, the spray device is a manually operable spray device in the sense that the spray mechanism is manually operable to expel a dose of said composition from the nozzle.

[0176] The spray mechanism can be operated by an actuator. The actuator can be a push actuator or a pull actuator. The actuator can include a trigger. The spray mechanism can include a manual pump. Optionally, the pump is one of the following: a positive displacement pump; a self-priming pump; or a reciprocating pump. Suitable spray devices include triggered spray, continuous / semi-continuous spray, finger pump spray, and spray output from a vibrating mesh device.

[0177] Preferably, the spray device is operable without the use of a propellant. In fact, a propellant-free spray device is preferred. This allows the spray to maintain the integrity and purity of the product, be free of propellant contamination, and preferably be environmentally friendly.

[0178] Preferably, the spraying device is pressurized. This can increase the duration and speed of the spray. Preferably, the spraying device is pressurized by a gas chamber separated from the reservoir containing the composition. The gas is preferably air or nitrogen. The spraying device may comprise an external container containing the composition and a pressurizing agent, wherein the composition is isolated from the pressurizing agent by being enclosed in a flexible bag (preferably airtight). This maintains complete formulation integrity so that only pure (i.e., not comprising a pressurizing agent) composition is dispensed. A preferred system is the so-called "bag in can" (or BOV, bag-on-valve technology). Alternatively, the spraying device may comprise a piston barrier mechanism, such as EarthSafe from Crown Holdings.

[0179] Preferably, the spraying device comprises a biodegradable plastic material.

[0180] The spray mechanism may further comprise an atomiser configured to break up the liquid dose into droplets and thereby assist in generating the fine aerosol in the form of a mist. Conveniently, the atomiser may comprise at least one of: a swirl chamber and a transverse dispersion chamber. Suitably, the atomiser is used to mix air with the aqueous fabric spray composition.

[0181] The particle size of the formulation when sprayed is 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 sprayed 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, most preferably 15 to 150 μm. This size allows for a balance between uniform distribution and adequate wetting of the fabric without potential fabric damage due to over-application of certain ingredients. Droplet size can be measured on a Malvern Spraytec instrument, where the peak maximum corresponds to the average droplet size. The parameter droplet size is the volume mean diameter, D[4,3].

[0182] Suitably, the jet has a duration of at least 0.4 seconds after actuation. Preferably, the jet has a duration of at least 0.8 seconds. A longer duration minimizes workload by maximizing coverage with each actuation of the jet device. This is an important factor for products designed for the entire surface area of a garment. Preferably, the jet duration is directly related to actuation, such that the jet output continues as long as the actuator is activated (e.g., as long as a button or trigger is depressed).

[0183] The spray reservoir may be a non-pressurized, manually or mechanically pre-pressurized device. The above also refers to a removable / refillable reservoir.

[0184] According to another aspect of the present invention, there is provided a replacement reservoir for the spray product according to the above aspect, the replacement reservoir being pre-filled with a volume of the spray composition to replenish the product. A suitable "refill kit" comprises one or more reservoirs. In the case of more than one reservoir, for example, two, three, four, five or more reservoirs, the contents of each reservoir (the aqueous fabric spray composition) may be the same as or different from those of the other reservoirs.

[0185] dose

[0186] Conveniently, the spray composition is provided as a liquid and the spray mechanism is operable to expel 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 0.35 ml, more preferably at least 0.4 ml, more preferably at least 0.45 ml, and most preferably at least 0.5 ml.

[0189] These dosages have been found to be particularly effective in achieving the desired spray effect without forming large, unsightly and wasteful droplets.

[0190] The dosage may alternatively be defined as milliliters per square meter of fabric. Preferably, the spray composition of the present invention is applied at 0.1 to 20 ml per square meter. More preferably, 0.5 to 15 ml per square meter, and most preferably, 1 to 10 ml per square meter.

[0191] How to use

[0192] In one aspect, a method for reducing odor or preventing odor from forming on a fabric surface is provided. This is achieved by spraying a composition as described herein onto a fabric that has been worn for a period of time. In other words, this can be described as a method for reducing the frequency with which clothing requires washing, allowing consumers to wear clothing for longer periods of time before washing is necessary.

[0193] This method can also be used to reduce wrinkles, prevent them from forming, or prevent fabric from becoming stiff.

[0194] use

[0195] In one aspect, a use of a composition as described herein is provided. The composition can be used to reduce or prevent odor from occurring on fabrics. Alternatively, a spray as described herein can be used to reduce wrinkles, prevent wrinkle formation, or prevent fabric from stiffening. Example

[0196] Example formulations:

[0197]

[0198] Dioctyl ether 1 – Cetiol OE from BASF

[0199] Hydrogenated ethylhexyl olive oil (and) hydrogenated olive oil unsaponifiables 2 -Plantasens Olive LD from Clarient

[0200] hydrogenated castor oil 3 – Eumulgin CO 40 from BASF

[0201] Prebiotics 4 – Pectin from Sigma Aldrich

[0202] Hydrogen sulfide test:

[0203] When the bacteria are given any sulfur source (L-cysteine hydrochloride or L-cystine dihydrochloride), they produce hydrogen sulfide gas. The production of hydrogen sulfide can be measured using lead acetate test paper, which turns darker when it reacts with hydrogen sulfide to produce lead sulfide. The color change can be quantified using the L*a*b* values measured by a spectrometer.

[0204] Four volunteers wore sari blouses for 12 hours. The underarm area of each blouse was cut into samples, one was untreated and the other was sprayed once with Composition 1. The samples were then placed in wells of growth medium (tryptic soy casein broth with 0.2% L-cysteine hydrochloride). Lead acetate test paper was placed over the wells attached to the inside base of the cover. After 24 hours, the lead acetate test paper was removed and the L*a*b* values were measured. The ΔE of each test lead acetate test paper sample was then calculated using the following formula by comparing the measured L*a*b* values with the L*a*b* values of the unused (control) lead acetate test paper:

[0205]

[0206] in:

[0207] L*2, a*2, b*2 are the values of lead acetate test paper

[0208] L*1, a*1, b*1 are the values of the reference lead acetate test paper

[0209] Unprocessed Composition 1 ΔE value relative to white control 39 24

[0210] A lower ΔE means the lead acetate paper is lighter, which means it reacts with less hydrogen sulfide, indicating a lower odor level.
