Description

[Background technology]

[0001] The permanent change in color of keratin fibers, particularly human hair, by application of hair dyes is well known. Complex chemical processes may be utilized to provide the consumer with the desired hair color and color intensity. Permanent hair dyes typically contain oxidative hair dye precursors, which can diffuse through the cuticle into the hair and into the cortex, where they can react with each other and with a suitable oxidizing agent to form the final dye molecules. Due to their large size, these resulting molecules cannot easily diffuse out of the hair during subsequent washing with water and / or detergent, thus resulting in the color permanence desired by the consumer. This reaction typically occurs in an aggressive environment at approximately pH 10, in the presence of an alkalizing agent, and in the presence of an oxidizing agent. Furthermore, consumers repeat this process periodically to maintain the desired hair color and shade, as well as color intensity, and to ensure continued and uniform coverage of the hair, including coverage of new hair growth.

[0002] Thus, the colorant composition should (i) provide a wide variety of resultant colors, (ii) be capable of being applied in a less aggressive pH environment, (iii) be capable of being applied using relatively low amounts of oxidizing agent, (iv) be easy to manufacture, have a suitable viscosity, and (v) be shelf-life stable.

[0003] When women encounter gray hairs, they almost always take one of two positions. First, there are those who have a trusting relationship with their hairdresser but are skeptical of the time, energy, and money required to dye their hair. This skepticism is often driven by the fact that dyeing gray hairs will cause them to grow out bit by bit from the roots. Second, there are those who accept the gray hairs as they are, strand by strand. They are likely to live with a natural, casual contentment; they have realistic expectations of aging and are okay with the gray hairs that will appear.

[0004] However, for various reasons, embracing the full grey hair by dying the rest of your hair grey may not be an option: you may feel that the grey does not look natural, you may not want to change the base grey colour, you may fear committing to continuing to dye your hair due to concerns about the transition to growth, and / or you may fear that once the grey colour fades, it may fade to a colour other than your natural grey (e.g. a brassy off-tone after fading). Summary of the Invention

[0005] Surprisingly, it has been found that the hair coloring compositions described herein can meet these needs not only at lower pH, but also with very small amounts of oxidizing agent. For example, the hair coloring compositions described herein have a pH of less than 9 and have a buffer system that maintains the pH of the composition between 6-8. Additionally, the hair coloring compositions described herein contain less than 2% by weight of at least one oxidizing agent, based on the total weight of the hair coloring composition. Additionally, the compositions exhibit low odor and substantially reduce damage to the hair fiber. Finally, the compositions described herein are compatible with current dye and dye precursor systems and provide excellent dye deposition with virtually no lift-up.

[0006] Also, it has been surprisingly found that the hair coloring compositions described herein address one or more of the above-mentioned fears that women who want to embrace gray hair may have. For example, the hair coloring compositions described herein provide a resultant gray color that fades within the gray color space and has little or no brassy off-tone appearance after fading. Furthermore, the compositions exhibit low odor, substantially reduce peroxide concentration, and substantially reduce hair fiber damage. Finally, the compositions described herein are compatible with current dye and dye precursor systems, providing excellent dye deposition and improved gray highlighting without substantial lift-up and without substantially altering the base gray hair color.

[0007] explanation: As used herein, the term "hair" to be treated may be "living", i.e. on a living body, or "non-living", i.e. a wig, hair piece or other collection of non-living keratinous fibers. Mammalian, preferably human, hair is preferred. However, wool, fur and other keratin-containing fibers are suitable substrates for compositions according to the present disclosure.

[0008] As used herein, the term "about" may allow for some variability in values ​​or ranges, for example, within 10%, within 5%, or within 1% of a stated value or the limits of a stated range.

[0009] Unless otherwise specified herein, the term "substantially" as used herein refers to a majority or majority of at least about 50%, 60%, 70%, 80%, 90%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.9%, 99.99%, or at least about 99.999% or more. In some cases, "substantially" means completely or 100%.

[0010] Unless otherwise specified herein, the term "substantially free" as used herein refers to a small or almost non-existent amount, such as less than about 10%, 5%, 2%, 1%, 0.5%, 0.01%, 0.001%, or less than about 0.0001%.

[0011] Values ​​expressed in range format should be interpreted in a flexible manner so that not only the numerical values ​​explicitly recited as range limitations, but also all individual numerical values ​​or subranges encompassed within the range are included as if each numerical value and subrange were explicitly recited. For example, a range of "about 0.1% to about 5%" or "about 0.1% to 5%" should be interpreted to include not only about 0.1% to about 5%, but also the individual values ​​(e.g., 1%, 2%, 3%, and 4%) and subranges (0.1% to 0.5%, 1.1% to 2.2%, 3.3% to 4.4%) within the indicated range. Unless otherwise indicated, the statement "about X to Y" has the same meaning as "about X to about Y". Similarly, unless otherwise indicated, the statement "about X, Y, or about Z" has the same meaning as "about X, about Y, or about Z".

[0012] In this document, the terms "a," "an," or "the" are used to include one or more unless the context clearly dictates otherwise. The term "or" is used to refer to a non-exclusive "or" unless otherwise indicated. Furthermore, any expressions or terms employed herein and not otherwise defined should be understood to be for descriptive purposes only and not for limiting purposes. The use of section headings is intended to aid in the reading of the document and should not be construed as limiting. Furthermore, information associated with a section heading may occur within or outside that particular section. Furthermore, all publications, patents, and patent documents referred to in this document are incorporated herein by reference in their entirety as if individually incorporated by reference. In the event of any inconsistent usage between this document and a document incorporated by reference, the usage of the incorporated reference should be considered as supplementary to the usage of this document, and in the event of an irreconcilable discrepancy, the usage of this document shall take precedence.

[0013] In the methods described herein, steps may be performed in any order without departing from the principles of the invention unless a temporal or operational order is explicitly recited. Furthermore, specified steps may be performed simultaneously unless express claim language dictates that they be performed separately. For example, a claimed step of performing X and a claimed step of performing Y may be performed simultaneously within a single operation, and the resulting process falls within the literal scope of the claimed process.

[0014] All percentages are by total weight of the composition unless otherwise stated. When multiple compositions are used during a treatment, the total weight to be considered is the total weight of all compositions simultaneously applied to the hair (i.e., the weight found "on the head") unless otherwise stated. All ratios are by weight unless otherwise stated. All molar concentrations are by total volume of the composition and are expressed as moles of ingredient in 1 liter of composition, or "moles / 1". When multiple compositions are used during a treatment, the total volume to be considered is the total volume of all compositions simultaneously applied to the hair (i.e., the volume found "on the head") unless otherwise stated.

[0015] As described herein, the present disclosure relates to a hair coloring composition comprising: i) at least one buffer system; ii) less than 2 wt. % of at least one oxidizing agent based on the total weight of the hair coloring or bleaching composition; iii) at least one gel network thickener system comprising: a) a first surfactant component selected from C14-30 alkyl phosphates, C14-C30 alkyl ether phosphate ester salts, and mixtures thereof; b) a second component selected from C14-C30 fatty alcohols; and c) a third surfactant component selected from polyoxyethylene C8-C30 alkyl ethers; wherein the composition has a pH of less than 9, and the buffer system maintains the pH of the composition between 6-8.

[0016] As described herein, the present disclosure provides at least one primary dye and at least one dye coupler each selected to provide a hair color in the CIE L*a*b* gray color space and a hair color that fades in the CIE L*a*b* gray color space, optionally at least one buffer system, at least one oxidizing agent less than 2% by weight based on the total weight of the hair coloring composition, and at least one gel network thickening agent system, wherein the hair coloring composition has a pH of less than 9, preferably about 8 or less, more preferably about 6 to about 8, and color fading of the hair color in the CIE L*a*b* gray color space is defined by the following L*a*b* values: -1 < a < 4, 0 < b < 12, and 25 < L < 80, relating to the hair coloring composition.

[0017] Buffer system According to the present disclosure, the composition may include at least one buffer system. The buffer system serves to maintain the pH of the composition described herein below 9. Further, the buffer system may serve to maintain the pH of the hair coloring composition described herein between 6 and 8.

[0018] The buffer system may be included in at least one oxidizing agent and at least one gel network thickening agent system. Or, the buffer system may be included as a component separate from at least one oxidizing agent and at least one gel network thickening agent system.

[0019] The buffer system can include a buffer acidic compound and a buffer alkaline compound. The buffer acidic compound is selected from the group consisting of organic acids and inorganic acids, such as the group consisting of sulfurous acid, sulfuric acid, hydrochloric acid, hyponitrous acid, nitrous acid, nitric acid, phosphoric acid, phosphorous acid, citric acid, malic acid, and mixtures thereof, or the group consisting of phosphoric acid, phosphorous acid, citric acid, malic acid, hydrochloric acid, hyponitrous acid, and mixtures thereof, or the buffer acidic compound is phosphoric acid, hydrochloric acid, hyponitrous acid, and mixtures thereof, or the buffer acidic compound is phosphoric acid.

[0020] The buffer alkaline compound is selected from the group consisting of alkali metal salts, amino acids and their salts, or the group consisting of glycine, alkali metal salts, amino acids, chlorides, nitrates and their salts, or the group consisting of chlorides, nitrates and / or phosphoric acid, alkali metal glycine and their salts, alkali metal phosphoric acid and its salts, or disodium phosphate and potassium chloride.

[0021] The buffer system may include a buffer acidic compound that is phosphoric acid and a corresponding buffer alkaline compound that is disodium phosphate. Alternatively, the buffer system may include a buffer acidic compound that is phosphoric acid and a corresponding buffer alkaline compound that is glycine, or a buffer acidic compound that is citrate and a corresponding buffer alkaline compound that is disodium phosphate, or a buffer acidic compound that is citrate and a corresponding buffer alkaline compound that is glycine.

[0022] The buffer acidic and alkaline compounds are present in amounts sufficient to provide a reference buffering effect equivalent to a buffer system containing 0.1% to 4% phosphoric acid and 0.1% to 4% disodium phosphate by weight of the total oxidizing agent in a ratio of phosphoric acid to disodium phosphate of 1:1 to 10:1, 1:1 to 5:1, or 1:2 to 1:1.

[0023] The buffer system may include a buffer acidic compound that is phosphoric acid and a corresponding buffer alkaline compound that is disodium phosphate, but any alternative buffer system may be used as long as it provides an equivalent buffering effect as the reference buffer system. The amount of the alternative buffer acidic compound may be calculated relative to the amount of phosphoric acid. The amount of the alternative buffer alkaline compound may be calculated relative to the amount of disodium phosphate.

[0024] Alkalizing Agent The hair coloring compositions described herein may include at least one alkalizing agent, which may function to adjust the pH of the hair coloring compositions described herein to a desired pH. The alkalizing agent includes a hydroxide ion source. In some examples, the alkalizing agent includes a hydroxide ion source of about 0.25 mol / L. Any source of these ions may be utilized. In particular, sources of sodium, potassium, lithium, calcium, magnesium, barium, ammonium hydroxide and salts, and mixtures thereof, may be used.

[0025] It should also be understood that when the compositions described herein are used as hair coloring kits containing individually packaged components, the concentration of the ion source in any given component can be increased in proportion to the mixing ratio of the components to achieve a concentration of at least about 0.25 moles / L upon mixing of the components to provide a composition for application to the hair.

[0026] pH of the composition

[0027] As referred to herein, the compositions of the present disclosure have a pH of less than 9, from about 8 to about 6.

[0028] The pH of the compositions can be measured using either a Mettler Toledo MP220 or MP225 pH instrument equipped with a standard laboratory pH electrode. The instrument is calibrated using standard calibration procedures with standard calibration buffers before each use.

[0029] Oxidizing agent The compositions according to the present disclosure may include or be used in combination with a composition that includes a source of at least one oxidizing agent that can function primarily to accelerate the oxidation of at least one primary dye precursor described herein so that it can react with at least one dye coupler. For example, the oxidizing agent may be included in a concentration sufficient to minimize lift-up but accelerate the oxidation of at least one primary dye described herein so that it can react with at least one dye coupler.

[0030] Oxidizing agents for use herein include water-soluble peroxygen oxidizing agents. As defined herein, "water-soluble" means that at least 0.1 g, 1 g, or 10 g of the oxidizing agent can be dissolved in 1 liter of deionized water under standard conditions.

[0031] Any oxidizing agent known in the art can be utilized in the present disclosure. Water-soluble oxidizing agents include inorganic peroxygen materials capable of generating hydrogen peroxide in an aqueous solution. Water-soluble peroxygen oxidizing agents are well known in the art and include inorganic peroxygen salt bleaching compounds such as hydrogen peroxide, inorganic alkali metal peroxides such as sodium periodate and sodium peroxide, organic peroxides such as urea peroxide and melamine peroxide, and alkali metal salts such as perborates, percarbonates, perphosphates, persilicates, persulfates, and the like. These inorganic peroxygen salts can be incorporated as monohydrates, tetrahydrates, and the like. Alkyl and aryl peroxides, and / or peroxidases can also be used. Mixtures of two or more such oxidizing agents can be used if desired. The oxidizing agents can be provided in an aqueous solution or as a powder that is dissolved prior to use. Preferred for use in compositions according to the present disclosure are hydrogen peroxide, persulfates, and combinations thereof.

[0032] According to the present disclosure, the composition comprises less than 2.5 wt.%, or less than 2 wt.%, of at least one oxidizing agent, based on the total weight of the hair coloring composition, for example, from about 0.1 wt.% to about 2 wt.%, from about 0.5 wt.% to about 1.5 wt.%, from about 0.2 wt.% to about 2 wt.%, from about 0.5 wt.% to about 1 wt.%, or from about 1 wt.% to about 1.9 wt.%, of at least one oxidizing agent, based on the total weight of the hair coloring composition.

[0033] Gel Network Thickener According to the present invention, the hair coloring and bleaching composition comprises a gel network thickener system. The gel network thickener system of the present invention is typically provided in a dye composition, which is then mixed with an oxidation composition. The gel network thickener system of the present invention is defined as a thickener system comprising a third system. The system comprises a first anionic surfactant component selected from C14-C30 alkyl phosphates, C14-C30 alkyl ether phosphate salts, and / or mixtures thereof, a second component selected from C14-C30 fatty alcohols, and a third nonionic surfactant component selected from polyoxyethylene C14-C30 alkyl ethers.

[0034] Those skilled in the art will recognize that gel network thickener systems typically have a complex structure of networked lamellar bilayers and / or vesicles, sometimes crystals. These systems are particularly desirable because they typically have a creamy appearance and feel.

[0035] In particular, the gel network system of the present invention allows for easy and efficient mixing of the dye composition with the oxidizing composition containing a hydrogen peroxide source. Moreover, the gel network system provides a desired mixed viscosity level, independent of the developer composition and its viscosity prior to mixing. The latter property is particularly beneficial in professional hair coloring applications, for example in hair salons, where it is often particularly desirable to allow flexibility to utilize different types of developer compositions and / or viscosities.

[0036] Without being bound by theory, it is believed that the gel network thickener system components described in the present invention have the proper geometric arrangement in the gel network lamellar bilayer, preventing the bilayer from detaching, and therefore resisting viscosity loss.Furthermore, it is believed that the nonionic surfactant of the present invention is more inhibited from swelling due to the high ionic strength in the dye composition, and the ionic surfactant provides stability, but after dilution with the oxidizing composition, the concentration of ions is reduced, causing the nonionic surfactant to re-swell, resulting in the necessary additional thickening.

[0037] The first surfactant component of the gel network thickener system is selected from C14-C30, preferably C14-C18 alkyl phosphates, C14-C30, preferably C14-C18 alkyl ether phosphate ester salts, and / or mixtures thereof. Preferably, the alkyl ether phosphate ester salts have an average value of 1-20, most preferably 1-10 ethylene oxide units.

[0038] According to the present invention, the gel network system of the present invention comprises as a second component a linear or branched C14-C30 fatty alcohol and / or a mixture thereof. Most preferably, the second component is selected from cetyl, stearyl, cetostearyl, or behenyl alcohol, or a mixture thereof. Typically, the second component may be included in the dye composition, or in the oxidation composition, or in both, and preferably, the second component is included in both compositions. The second component helps to stabilize the gel network system and also helps to maintain the desired rheological range, especially at the upper limit, to prevent excessive stickiness.

[0039] The third surfactant component of the gel network thickener system is a non-ionic surfactant selected from polyoxyethylene C14-C30 alkyl ethers containing one or more polyethylene oxide chains, preferably having at least 50, preferably about 50-200, most preferably about 100-200 ethylene oxide units. Suitable surfactants include steareth-100, steareth-150, steareth-200, and mixtures thereof. The third surfactant component acts as a co-emulsifier and stabilizer for the gel network system. Additionally, without being bound by theory, the third surfactant aids in the formation of a soft, smooth composition.

[0040] Multiple surfactants and / or components of each of the specific classes of surfactants and components listed above may be used in the gel networks of the present invention.

[0041] Radical Scavenger The first composition and / or the second composition may include one or more radical scavengers. The one or more radical scavengers in the first composition and / or the second composition may be present in an amount sufficient to reduce damage to hair during an oxidative bleaching or coloring process.

[0042] The radical scavenger(s) may be a species capable of reacting with a radical species, preferably a carbonate radical, to convert the radical species to a less reactive species through a series of fast reactions. The radical scavenger(s) may be advantageously selected such that the radical scavenger(s) is different from the alkalizing agent and / or is present in an amount sufficient to reduce damage to the hair during the coloring / bleaching process.

[0043] The one or more radical scavengers of the first composition and / or the second composition may be selected from the group consisting of benzylamine, glutamic acid, salicylic acid, imidazole, di-tert-butylhydroxytoluene, hydroquinone, catechol, and mixtures thereof.

[0044] Hair dye The hair compositions of the present disclosure are preferably hair coloring compositions that include oxidative dye compositions. Such compositions include oxidative hair dye precursors (also known as "primary intermediates," "primary dyes," or "dye intermediates," such as at least one primary dye described herein) that deliver a variety of hair colors to hair. These small molecules are activated by an oxidizing agent and react with additional molecules or dye couplers to form larger colored complexes in the hair shaft.

[0045] The hair dye precursors can be used alone or in combination with other hair dye precursors, and one or more can be used in combination with one or more couplers. Couplers (also known as "color modifiers" or "secondary intermediates") are generally colorless molecules that can form color in the presence of activated precursors and are used with other precursors or couplers to produce specific color effects or stabilize color. The choice of precursors and couplers is determined by the color, shade, and intensity of the coloring desired. The hair dye precursors and couplers can be used alone or in combination herein to provide dyes with a variety of shades ranging from ash blonde to black, but preferably gray in the case of this disclosure.

[0046] These compounds are well known in the art and include aromatic diamines, aminophenols, aromatic diols, and their derivatives (a representative but non-exhaustive list of oxidation dye precursors can be found in Sagarin, “Cosmetic Science and Technology”, “Interscience, Special Edn.

[0062] In certain embodiments, the composition comprises a chelating agent selected from the group consisting of diethylenetriamine-N,N',N''-polyacid, diethylenetriaminepentaacetic acid (DTPA), diethylenetriaminepenta(methylenephosphonic acid) (DTPMP), diamine-N,N'-dipolyacid, monoaminemonoamide-N,N'-dipolyacid, ethylenediaminedisuccinic acid (EDDS), etidronic acid (HEDP), salts thereof, derivatives thereof, and mixtures thereof.

[0063] The chelating agent may be included in the at least one oxidizing agent and the at least one gel network thickener system, or may be included as a separate component from the at least one oxidizing agent and the at least one gel network thickener system, but in most cases, for stability reasons, the chelating agent is usually present along with the oxidizing agent.

[0065] polysaccharide The present invention further includes polysaccharides. Polysaccharides as used herein include, for example, glucans, modified and unmodified starches (e.g., from cereals such as wheat, corn or rice, vegetables such as yellow pea, and tubers such as potato or cassaya), amylose, amylopectin, glycogen, dextran, cellulose and its derivatives (methylcellulose, hydroxyalkylcellulose, ethylhydroxyethylcellulose, and carboxymethylcellulose), mannan, xylan, lignin, araban, galactan, galacturonan, chitin, chitin, glycan ... The gums are selected from among tosan, glucuronoxylan, arabinoxylan, xyloglucan, glucomannan, pectic acid and pectin, alginic acid and alginates, arabinogalactan, carrageenan, agar, glycosaminoglucan, gum arabic, tragacanth gum, ghatti gum, karaya gum, carob gum, galactomannans such as guar gum, and its non-ionic derivatives (hydroxypropyl guar) and biopolysaccharides such as xanthan gum, gellan gum, welan gum, scleroglucan, succinoglycan, and mixtures thereof.

[0066] For example, suitable polysaccharides are described in "Encyclopedia of Chemical Technology" by Kirk-Othmer, Third Edition, 1982, Vol. 3, pp. 896-900, and Vol. 15, pp. 439-458, "Polymers in Nature" by E. A. MacGregor and C. T. Greenwood, published by John Wiley & Sons, Chapter 6, pp. 240-328, 1980, and "Industrial Gums - Polysaccharides and their Derivatives", edited by Roy L. Whistler, Second Edition, published by Academic Press Inc.

[0067] The polysaccharide is preferably a biopolysaccharide, particularly preferred are biopolysaccharides selected from xanthan gum, gellan gum, welan gum, scleroglucan or succinoglycan, such as the material sold under the name Keltrol® T by the company Kelco and the material sold under the name Rheozan® by the company Rhodia Chimie, and mixtures thereof. Most preferred are xanthan gum, succinoglycan and mixtures thereof, most preferred is xanthan gum.

[0068] The composition according to the present invention comprises at least about 0.05% of said polysaccharide, preferably about 0.05% to 0.125% of said polysaccharide, by weight of the composition.

[0069] Without wishing to be bound by theory, it is believed that the polysaccharides act as plasticizers and adhesion enhancers, particularly at the levels described above, which aids in improving root attachment.

[0070] viscosity According to the present invention, the composition has a viscosity of 9-16 Pas, preferably 9-15 Pas, more preferably 10-14 Pas, most preferably 11-13 Pas. In another application, it has a viscosity of 1-6 Pas, preferably 2.5-4 Pas. The viscosity is measured according to the test method defined below. This viscosity range allows the hair salon professional maximum flexibility in utilizing one of the many application techniques that any particular client may require, by providing a composition that has conditioner-like properties and is not too thick or sticky.

[0071] Additional Ingredients The compositions of the present disclosure may further comprise additional ingredients, including, but not limited to, additional thickeners and / or rheology modifiers, solvents, enzymes, additional surfactants, conditioning agents, carriers, antioxidants, stabilizers, chelating agents, perm activators, fragrances, reducing agents (thiolactic acid), hair swelling agents and / or polymers, some of which are described in more detail below.

[0072] In some instances, the compositions of the present disclosure may further comprise up to about 10% by weight of charcoal, e.g., from about 1% to about 5% by weight, from about 3% to about 9% by weight, or from about 0.1% to about 5% by weight of charcoal, e.g., activated charcoal.

[0073] In some instances, the composition of the present disclosure may further comprise at least one agent that provides benefits beyond color. For example, at least one agent that provides benefits beyond color can make hair more manageable. One example of such an agent is at least one conditioning agent. Examples of conditioning agents include silicone materials, aminosilicones, fatty alcohols, polymeric resins, polyol carboxylic acid esters, cationic polymers, cationic surfactants, insoluble oils and oil-derived materials, and mixtures thereof. Specific examples of oils include mineral oil, glycerin, and sorbitol, and mixtures thereof.

[0074] How to use It will be understood that the examples of uses and embodiments described herein are for illustrative purposes only, and various modifications or changes in light thereof will be suggested to those skilled in the art without departing from the scope of the present disclosure.

[0075] After several minutes of mixing, particularly to ensure uniform application to all hairs, the compositions described herein are allowed to remain on the hair for a sufficient time (usually about 2-60 minutes, typically about 30-45 minutes) for the at least one primary dye and at least one dye coupler to react. The consumer then rinses the hair thoroughly with water and allows it to dry. It is observed that the hair has changed color from its original color to the desired color.

[0076] If present in the hair coloring compositions described herein, the optional conditioning agent may be provided in a separate additional container. The hair coloring compositions described herein may be mixed with the optional conditioning agent immediately prior to use and applied together, or the conditioner container may be applied as an immediate post-treatment (after any optional rinsing step) to the coloring compositions described herein.

[0077] According to the present disclosure, the method of coloring hair also includes an embodiment in which the hair coloring composition is applied to the hair and the mixture is allowed to work for several minutes (to ensure even application to all hairs). The composition is then allowed to remain on the hair for less than about 20 minutes, less than about 15 minutes, about 5 minutes to about 10 minutes, 2 minutes to about 60 minutes, about 40 minutes, or about 10 minutes to allow color development. The consumer then rinses the hair thoroughly with water and allows the hair to dry and style as usual. Such a method provides additional convenience to the consumer by allowing for faster coloring.

[0078] The above-mentioned kits are well known in the art, and the compositions in each container can be manufactured using any one of the standard approaches, including a) the "oil-in-water" process, b) the "phase inversion" process, and c) the "one-pot" process. For example, when using the "oil-in-water" process, the surfactant of the present disclosure is added to about 50% of the total water volume of the composition at about 90°C, homogenized for 15-30 minutes, and then cooled to room temperature to form a gel network thickener premix. This premix is ​​then cooled and mixed with the remaining amount of water, other optional ingredients, and an oxidizing agent or hydroxide ion source, thus forming the first or second part of the above-mentioned coloring kit.

[0079] The present disclosure can be utilized in a variety of packaging and dispensing devices. These dispensing devices can be provided in the form of separate devices that can be used independently or in combination with each other. Typically, the hair coloring compositions are contained in separate single or multi-compartment containers so that the compositions can be stored separately from each other before use. The compositions are then mixed together by a mixing means and then applied to the consumer's hair by an application means. Thus, for example, in the hair coloring compositions described herein, the components corresponding to at least one oxidizing agent (the oxidizing agent may also be referred to as a "developer"), less than 2% by weight based on the total weight of the composition, are contained in a separate container from the other components, such as the buffer system, the gel network thickener system, the primary dye (if present), and at least one coupler (if present). Both sets of components are mixed before use. A kit is disclosed that includes a first part containing at least one oxidizing agent and a second part containing other components for obtaining a hair coloring or bleaching composition as defined herein or for obtaining a hair coloring composition as defined herein.

[0080] One common packaging device that may be used in the present disclosure includes storing the developer in a container such as a bottle, tube, aerosol, or sachet, and storing the dye composition separately in an additional compartment in the developer container, or in a separate container that may be the same, for example, a dual sachet or aerosol system, or different, for example, a bottle and tube system. In some instances, the hair coloring compositions described herein may further include a pigment that exhibits the final color developed from the hair coloring composition. The pigment itself need not impart color to the hair. A dye or dye system may be present, which, for example, upon reaction with the developer, produces the final color developed from the hair coloring composition described herein.

[0081] The consumer can mix the dye composition with the developer composition, which comprises at least one primary dye and at least one dye coupler, by any means. This may simply involve the use of a mixing bowl into which the lotions are dispensed and then mixed, or the use of a mixing means such as a tool. Alternatively, it may involve adding one composition to a container of the other composition (typically the dye lotion is added to the developer lotion), followed by manual shaking or mixing with a tool. Another system involves piercing or replacing a seal located between separate compartments of the dye and developer compositions in a single container or sachet, followed by manual mixing within the container or in separate and / or additional containers.

[0082] One example of such a device is the so-called "Twist & Go" device. These devices allow a consumer to twist the base of a container (e.g., separate or the same container) that holds at least one primary dye and at least one dye coupler, opening a connection and exposing the base of a bottle that holds at least one primary dye and at least one dye coupler, and the top of the bottle that holds the developer. The two components are mixed and the consumer dispenses the product by squeezing the flexible top portion of the dispensing bottle.

[0083] Alternatively, more complex devices can be utilized to mix the developer, at least one primary dye, and at least one dye coupler upon actuation of dispensing. One example of such a complex system is a dual aerosol system, such as a bag-in-can or piston. The at least one primary dye, at least one dye coupler, and developer are stored separately in two aerosol cans in one device, and a propellant is used to apply pressure to the contents of the bag or piston in the can, and a valve provides control of dispensing. When the consumer activates the valve, the at least one primary dye, at least one dye coupler, and developer are dispensed simultaneously from the can and mixed by a static mixer just prior to dispensing the product onto the hair. The ratio of the at least one primary dye, at least one dye coupler, and developer can be manipulated by the viscosity of the product, the pressure in the can, or by changing the flow channel size through the valve. Additionally, the product can be whipped and delivered in a mousse form.

[0084] Another example of such a complex system utilizes a dual piston screw system. At least one primary dye, at least one dye coupler, and developer are held in separate piston cylinder systems within the system, and when the consumer activates a button, the two screws rotate and the internal dual pistons pressurize the liquids within the cylinders, forcing the product through a mixing station and out of a dispensing nozzle. The ratio of the at least one primary dye, at least one dye coupler, and developer can be manipulated by the diameter of the packaging cylinder. Additionally, an in-line static mixer can be used to assist in mixing, and such a system can be fully disposable or fully refillable.

[0085] Yet another system utilizes one or more manual pumps. The product can be premixed in a collapsible sachet. When the consumer activates the pump, the liquid in the pump is dispensed. When the manually activated pump returns to an upright position, the product is forced out of the collapsible sachet. Alternatively, a dual system can be set up using two sachets and two pumps to deliver at least one primary dye, at least one dye coupler, and developer lotion to the hair. Alternatively, a single pump connected to two sachets can deliver the product by incorporating a mixing point within the pump. Another embodiment uses a rigid bottle and a dip tube to connect the product to the pump system. Finally, a delaminating bottle can be used in combination with a manual pump, where the inner layer of the bottle peels away from the outer layer of the bottle, forcing the contents of the bottle out.

[0086] Typically, these complex systems offer the advantage of being able to apply the product independently of the orientation of the product.

[0087] The above mentioned devices may also be used in combination with product delivery and / or application tools to aid in the application of the product to the hair. Again, these devices may be of a very simple nature such as a nozzle attached to one of the containers or a separate applicator device such as a comb or brush. Such combs and brushes can be adapted to achieve specific effects such as quick and even coverage, root / hairline touch-up, highlights or streaks. Alternatively, the container or one of the containers may be provided with a comb attached to or instead of the dispensing nozzle, whereby the product is dispensed through dispensing openings located in the hollow tines and comb tines. The comb tines may be provided with single or multiple openings along the tines to improve application and evenness of the product, especially from root to tip. Dispensing of the product can be achieved by mechanical pressure applied to the container, for example a delaminating bottle or any of the above mechanisms described herein. The comb can be provided on the container for easy application and can be positioned vertically (so-called vertical combs) or at an angle to allow the consumer access to all areas. All devices can be designed to be interchangeable, providing the consumer with a variety of different tools for hair application.

[0088] Additional device technology can be used to aid in the penetration of the product into the hair, examples of such technology include heat devices, ultraviolet devices, and ultrasonic devices.

[0089] Viscosity Test Method Viscosity measurements are performed on a controlled stress rheometer using AR500, AR1000, or AR2000 type or equivalent equipment manufactured by TA Instruments. A 6 cm flat acrylic cross-hatched parallel plate geometry (TA item 518600.901), and a stainless steel cross-hatched base plate (TA item 570011.001) are used. The rheometer is prepared for flow measurements according to standard manufacturer's procedures. The gap of the parallel plate geometry is set to 1000 microns. The conditions for programming the flow procedure into the rheometer are as follows: a continuous stress ramp 0.1 to 300 Pa for 2 minutes at 25°C, including 250 measurement points in linear mode. The final hair coloring mixture is prepared by mixing the required portions of the composition, for example in a professional hair stylist's mixing bowl with a professional hair stylist's brush, to ensure a uniformly mixed consistency (standard mixing time 1 minute). The product is loaded into the geometric shape according to standard procedures and the measurements are started 5 minutes after the preparation of the mixture. The shear stress value at a shear rate of 10 s-1 is obtained from the shear stress vs. shear rate curve. The corresponding viscosity is calculated by dividing the obtained shear stress by 10.

[0090] Further embodiments of specific components of the present disclosure are described below.

[0091] Permanent changes in hair color through the application of hair dyes are well known. Complex chemical processes are utilized to provide consumers with the desired shade and color intensity. Permanent hair dyes typically contain oxidative dye precursors, which can diffuse through the cuticle into the hair and into the cortex where they react with each other and with a suitable oxidizing agent to form the final dye molecules. The resulting molecules are large in size and therefore cannot easily diffuse out of the hair during subsequent washing with water and / or detergent, thus resulting in the permanence of color desired by the consumer. This reaction typically occurs in an aggressive environment at approximately pH 10 in the presence of an alkalizing agent and an oxidizing agent. Typically, an oxidizing composition (also called a developer and / or oxidizing component) containing an oxidizing agent, a dye composition (also called a tint or dye component) containing an alkalizing agent, and precursor dye molecules, if present, are mixed immediately prior to use. The consumer repeats this process periodically to maintain the desired hair color and shade, as well as color intensity, and to ensure continued and even coverage of the hair, including coverage of new hair growth.

[0092] definition As used herein, the term "hair" to be treated may be "living", i.e. on a living body, or "non-living", i.e. a wig, hair piece or other collection of non-living keratinous fibers. Mammalian, preferably human, hair is preferred. However, wool, fur and other keratin-containing fibers are suitable substrates for the compositions according to the invention.

[0093] By "hair coloring" composition is meant a composition suitable for changing the color of hair. The hair coloring composition is hereinafter referred to as "the composition" unless otherwise specified. The hair coloring composition may contain oxidative dye precursors, direct dyes, or may be dye-free or substantially dye-free in the case of bleaching only compositions in which the color change is caused primarily by the decomposition of the natural melanin contained in the hair shaft by an oxidizing agent. As used herein, the term "hair coloring" composition encompasses hair bleaching and hair oxidation dyeing products.

[0094] All percentages are by weight of the hair coloring composition, i.e., the ready-to-use composition, unless otherwise specified. When multiple compositions are used during a treatment, the total weight to be considered is typically the total weight of all compositions simultaneously applied to the hair (i.e., the weight as seen "on the head") resulting from mixing the oxidizing composition (also called the developer and / or oxidizing composition / ingredients) with the dye composition (also called the tint and / or dye composition / ingredients), unless otherwise specified. All ratios or percentages are by weight or weight percent, unless otherwise specified.

[0095] Other Ingredients In addition to the components described above, the compositions according to the present invention may contain other components to further enhance the properties of the composition, unless these are excluded by the claims.

[0096] Suitable additional ingredients include, but are not limited to, solvents, oxidizing agents, alkalizing agents, oxidative dye precursors, direct dyes, chelating agents, radical scavengers, pH adjusters and buffers, thickening and / or rheology modifiers, carbonate ion sources, peroxymonocarbonate ion sources, anionic, cationic, nonionic, amphoteric or zwitterionic surfactants, and mixtures thereof, anionic, cationic, nonionic, amphoteric or zwitterionic polymers, and mixtures thereof, fragrances, enzymes, dispersing agents, peroxide stabilizers, antioxidants, natural ingredients (e.g., proteins, proteinaceous compounds, and botanical extracts), conditioning agents (e.g., silicones and cationic polymers), ceramides, preservatives, opacifying and pearlizing agents (e.g., titanium dioxide and mica), and mixtures thereof.

In particular, vol. 2, sections 3 (Chemical Classes) and 4 (Functions) are useful for identifying specific adjuvants that achieve a specific purpose or purposes. Some of these ingredients are discussed below, although the disclosure is of course not exhaustive.

[0102] Oxidizing agent The composition according to the present invention may further comprise at least one source of oxidizing agent. Any oxidizing agent known in the art may be used. The preferred oxidizing agent is a water-soluble peroxygen oxidizing agent. As used herein, "water-soluble" means that at least about 0.1 g, preferably about 1 g, more preferably about 10 g of the oxidizing agent can be dissolved in 1 liter of deionized water at 25°C under standard conditions. The oxidizing agent is useful for the initial solubilization and decolorization (bleaching) of melanin and promotes the oxidation of the oxidative dye precursors in the hair shaft (oxidative dyeing). In short, it is possible to completely remove the color by using a reducing or bleaching agent.

[0103] Typically, the composition may contain a total amount of oxidizing agent in the range of from about 0.1% to about 10%, alternatively from about 1% to about 7%, alternatively from about 2% to about 5%, by weight of the composition.

Mixtures of two or more such oxidizing agents can be used if desired. The oxidizing agents may be provided in aqueous solutions or as powders that are dissolved before use.

[0106] In certain embodiments, the compositions comprise a water-soluble oxidizing agent selected from the group consisting of hydrogen peroxide, percarbonates (which can be used to provide both an oxidizing agent and a source of carbonate and or ammonium ions), persulfates, and mixtures thereof.

[0107] When the composition of the present invention is obtained by mixing a developer composition and a tint composition before use, the oxidizing agent may be present in the developer composition. The developer composition may be based on any desired formulation framework, including any commercially available product, for example an oil-in-water emulsion. A typical developer composition contains about 6% or about 9% H2O2 by weight of the total developer composition. A commercial example is Welloxon® emulsion marketed by Wella, which has about 6% and about 9% H2O2, respectively, and contains water, H2O2, cetearyl alcohol, ceteareth-25, salicylic acid, phosphoric acid, disodium phosphate, and etidronic acid as INCI ingredients.

Exemplary alkalizing agents are ammonia and / or monoethanolamine. Preferably, when present, the ammonium ions and carbonate ions are present in the composition in a weight ratio of 3:1 to 1:10, alternatively 2:1 to 1:5.

[0111] When the composition of the invention is obtained by mixing a developer with a hair dye composition before use, the alkalizing agent is usually present in the hair dye composition.

[0112] Oxidation dye precursors The compositions according to the invention may further comprise oxidation dye precursors, which are usually classified as either primary intermediates (also known as developers) or couplers (also known as secondary intermediates).

[0183] Ionic Strength The compositions of the present invention may further have an ionic strength, as defined herein, of less than about 1.35 moles / kg, alternatively from about 0.10 to about 0.75 moles / kg, alternatively from about 0.20 to about 0.60 moles / kg. Without being bound by theory, it is believed that the ionic strength value may also affect the resulting viscosity and root adhesion properties of the composition. Ionic strength may be affected by salt sources such as dyes, sodium sulfate, ammonium carbonate antioxidants, and chelating agents such as EDDS. Dyes tend to have the greatest effect on ionic strength, so the dosage to impart any particular shade must be considered in terms of ionic strength and dye results to avoid viscosity and root adhesion issues.

[0184] The ionic strength of a composition is a function of the concentrations of all ions present in the solution and is represented by the formula: [ka] (In the formula, m i = molality of ion i (M = mol / Kg H2O), and z i = the number of charges on that ion, summed over all ions in the solution). For example, for a 1:1 electrolyte, such as sodium chloride, the ionic strength is the same as the concentration, but for MgSO4, the ionic strength is four times higher. Multivalent ions generally contribute more strongly to ionic strength.

[0185] For example, the ionic strength of a mixture of 0.050M Na2SO4 and 0.020M NaCl is: I = 1 / 2((2 × (+1)2 × 0.050) + (+1)2 × 0.020 + (-2) 2 ×0.050+(-1) 2 ×0.020)=0.17M.

[0186] How to use / Kit It will be understood that the examples of uses and embodiments described herein are for illustrative purposes only, and that various modifications or changes in light thereof may be suggested to those skilled in the art without departing from the scope of the invention.

[0187] Oxidative hair dye compositions for retail use are usually sold in kits containing separately packaged components in separate containers, such as a dye component (emulsions are also called "dye creams" or solutions are also called "dye liquors") containing an oxidizing agent, typically ammonia, in a suitable carrier, and an oxidizing component (emulsions are also called "hydrogen peroxide creams" or solutions are also called "hydrogen peroxide liquors") containing an oxidizing agent, typically hydrogen peroxide. The consumer mixes the dye and oxidizing components together just before use and applies to the hair. Similarly, retail bleaching compositions are usually sold as kits, also containing two or three separately packaged components in two or three separate containers. The first component contains a source of ammonium ions (e.g., ammonia), the second component contains an oxidizing agent, and the third (optional) component contains a second oxidizing agent. The bleaching composition is obtained by mixing the above-mentioned compositions just before use.

[0188] For the professional hair salon market, the hair dye components and the oxidizing and / or bleaching compositions are usually supplied separately to allow the professional to select the combination that suits him or her.

[0189] After mixing the mixture for a few minutes (to ensure even application to all hairs), the oxidative dye composition is allowed to remain on the hair for a sufficient time for coloring to occur (usually about 2 minutes to about 60 minutes, typically about 30 minutes to about 45 minutes). The consumer or salon professional then rinses the hair thoroughly with water and / or shampoo and allows it to dry. The hair is observed to have changed from its original color to the desired color.

[0190] In both retail and professional applications, a conditioning agent may also be provided as an option. In this embodiment, all three compositions can be mixed and applied together immediately prior to use, or the conditioning agent can be applied (after an optional rinsing step) as an immediate post-treatment after the oxidative dye composition or bleach composition obtained from a mixture in another container.

[0191] The kit may also include, as optional components, a pretreatment composition and / or a color refresher composition. Such color refresher compositions include at least one preformed dye and may be applied to the hair immediately after oxidative coloring, i.e., from about 1 minute after application of the oxidative hair dye or bleach, up to about 60 days after application. These color refresher compositions can be used to increase the initial color obtained or to enhance color during the wash and style cycle until the next oxidative coloring or bleaching event.

[0192] viscosity According to the invention, the dye composition and the oxidizing composition can be prepared independently of each other as so-called thin liquids or thick creams. Typically, thin liquids have a viscosity of less than about 1000 cPs. Thick creams typically have a viscosity of about XXX cPs.

[0193] Upon mixing the dye and oxidizing composition, the resulting hair coloring and / or bleaching composition preferably has a viscosity of about 1000 to about 60000 cPs, alternatively about 2000 to about 30000 cPs, alternatively about 3000 to about 25000 cPs. Viscosity is measured using a Brookfield viscometer fitted with a cone and plate. For viscosities ranging from about 0 to about 12000 cPs, a Brookfield DV-11 viscometer with an S42 plate is used. A 2 ml sample of the composition is equilibrated at 26.7° C. for 3 minutes and then read at 1 rpm. For viscosities ranging from about 12,000 to about 60,000 cPs, a Brookfield DV-1 viscometer with an S52 plate is used. A 0.5 ml sample of the composition is equilibrated at 26.7° C. for 1 minute and then read at 1 rpm.

[0194] If viscosity values ​​differ between retail and commercial use, this should be stated.

[0195] Manufacturing method The above-mentioned kits are well known in the art, and the compositions in each container can be manufactured using any one of the standard approaches, including a) the "oil-in-water" process, b) the "phase inversion" process, and c) the "one-pot" process. For example, when using the "oil-in-water" process, the surfactant of the present invention is added to about 50% of the total water volume of the composition at about 90°C, homogenized for 15-30 minutes, and then cooled to room temperature to form a gel network thickener premix. This premix is ​​then mixed cold with the remaining amount of water, other optional ingredients, and / or oxidizing agent, thus forming the first and second component portions of the above-mentioned bleaching or coloring kit.

[0196] Packaging and dispensing equipment The present invention may be provided in a variety of packaging and / or dispensing devices. These dispensing devices may be provided in the form of separate devices that may be used independently or in combination with one another. Typically, the hair coloring or bleaching compositions are contained in separate single or multi-compartment containers so that the compositions can be stored separately from one another before use. The compositions are then mixed together by a mixing means and then dispensed from the device and applied to the consumer's hair by an application means.

[0197] The most common packaging devices that can be used in the present invention include storing the developer in a container such as a bottle, tube, aerosol, or sachet, and storing the dye lotion separately in an additional compartment in the developer container, or more preferably in a separate container that can be the same, such as a dual sachet or aerosol system, or different, such as a bottle and tube system. Any combination may be used, typically depending on the type of composition stored, i.e., whether it is a thick or thin type. The consumer or hair salon professional may mix the oxidation and dye components by any means. This may include the use of a mixing bowl into which the composition is dispensed and then mixed, preferably the use of a mixing means such as a tool. Alternatively, it may involve adding one composition to a container of the other composition (typically the dye composition is added to the oxidation composition), followed by manual shaking or mixing with a tool. Another system involves piercing or replacing a seal located between the separate compartments of the dye and oxidation compositions in a single container or sachet, followed by manual mixing within the container or in a separate and / or additional container.

[0198] The above mentioned devices may also be used in combination with product delivery and / or application tools to aid in the application of the product to the hair. Again, these devices may be of a very simple nature such as a nozzle attached to one of the containers, or a separate applicator device such as a comb or brush. Such combs and brushes can be adapted to achieve specific effects such as quick and even coverage, root / hairline touch-up, highlights or streaks. Alternatively, the container or one of the containers may be provided with a comb attached to or instead of the dispensing nozzle, whereby the product is dispensed through dispensing openings located in the hollow tines and comb tines. The comb tines may be provided with single or multiple openings along the tines to improve application and evenness of the product, especially from root to tip. Dispensing of the product can be achieved by mechanical pressure applied to the container, for example a delaminating bottle or any of the above mechanisms described herein. The comb may be provided on the container for easy application and may be positioned vertically (so-called vertical combs) or at an angle to allow the consumer access to all areas. All devices may be designed to be interchangeable, providing the consumer with a variety of different tools for hair application.

[0199] The application device may also include devices that assist in achieving specific effects such as highlighting, such as highlighting combs, brushes and tools, foils and highlighting caps, etc. Highlighting devices may also be used that include a hinged device into which a quantity of composition is placed and then used to apply the composition to predetermined / selected hair strands.

[0200] Additional device technology can be used to aid in the penetration of the product into the hair, examples of such technology include heat devices, ultraviolet devices, and ultrasonic devices.

[0201] Forms Alternatively, the composition of the present invention may be provided in the form of a foam that is applied to hair.The formation of foam is typically achieved by using a foaming agent that is incorporated in the mixed composition (typically present in either the oxidizing composition, or the dye composition, or both) in conjunction with a manually operated foaming device.Such manually operated foaming devices are known in the art and include aerosol devices, squeeze foamers, and pump foamers.

[0202] Suitable foaming agents include surfactants, such as anionic, nonionic, and amphoteric surfactants, (nonionic surfactants are preferred); polysaccharides (as described herein); polyvinylpyrrolidone and its copolymers; acrylic polymers, such as acrylates copolymer (Aculyn 33) and acrylates / steareth-20 methacrylate (Aculyn 22); C12-C24 fatty acids, such as stearates, and mixtures thereof.

[0203] Hair dyeing method The hair coloring composition can be obtained by mixing the color composition and the developer composition just before use. A sufficient amount of the mixture is applied to the hair, generally about 60 to about 250 grams, according to the amount of hair. Upon such preparation, the composition is applied to the hair to be dyed and kept in contact with the hair for a time effective to dye the hair. Typically, the hair dye composition is allowed to act on the hair for about 2 minutes to about 60 minutes, preferably about 15 minutes to about 45 minutes, more preferably about 30 minutes, at a temperature ranging from 15°C to about 50°C. The hair is then rinsed with water to remove the composition and dried. If necessary, the hair is washed with a shampoo, rinsed with water or a weak acid solution, such as a citric acid or tartaric acid solution, and dried. Optionally, a separate conditioning product may also be provided.

[0204] Thus, a method of treating hair with the composition comprises: (i) providing a tint composition comprising a gel network thickener system, and, if present, an alkalizing agent and an oxidized precursor dye and / or a direct dye; (ii) providing a developer composition comprising an oxidizing agent; (iii) mixing the developer composition with the dye composition to obtain a hair colouring composition according to the present invention; (iv) applying to the hair a composition for oxidation dyeing of keratinous fibers.

[0205] Glycerol may be included in the dye composition or in the developer composition, or may be distributed in both components. Typically, glycerol is included at least in the dye composition, where it acts as a solvent for the dye.

[0206] The method may further include waiting a period of time, typically between 2 minutes and 60 minutes, followed by rinsing the hair coloring composition from the hair. The hair coloring composition may be applied to the hair via an applicator bottle or brush. Common highlight applicator foils, caps, and specialized applicators may be used, allowing full head or partial single strand (highlight application), but also freehand techniques such as balayage with a brush and / or comb. The composition may also be applied as a mousse, via a manual spray, pressurized container, or aerosol mousse. The composition may be dispensed as a solid form to which water is added to generate an oxidizing agent and form a thickened vehicle suitable for hair coloring.

[0207] Manufacturing method - kit The coloring compositions of the present invention, and the corresponding tint and developer compositions, can be manufactured by conventional processes known in the art for manufacturing oxidation dye products, by mixing the ingredients of each component composition in a suitable container and then packaging them in suitable individual containers, which may be packaged, for example, in plastic or aluminum bottles.

[0208] In particular, the present invention may be provided as a kit comprising different components to be mixed by a consumer or salon stylist to obtain a hair dye composition according to the present invention. Such a kit may comprise a colour composition and a developer composition, as described above.

[0209] The kit may be presented in a single package containing the color composition, the developer composition, and optionally separate containers for a conditioner, color refresher or other hair treatment product, instructions for use, gloves. The instructions for use include the steps of the method described above and, optionally, provide visual cues or pictures for the desired steps of the method. Kits are typically sold as retail products, with each component containing enough material to prepare a hair dye composition for a single use.

[0210] The composition can be dispensed as a foam, for example, using a pump or a manually actuable non-aerosol dispenser such as a squeeze foamer, an aerosol mousse, etc. See, for example, EP613,728B1, WO97 / 013585A1, EP1,716,933A1, US3,709,437, US3,937,364, US4,022,351, US4,147,306, US4,184,615, US4,615,467 and FR2,604,622.
