Description:
COSMETIC COMPOSITION This invention relates to aqueous cosmetic compositions that are suitable for use as make-up removers.

Make-up, once applied to the skin and/or eyes, has conventionally only a limited life or purpose. Therefore, make-up is generally removed and may be reapplied later.

The removal and reapplication process may be a daily or twice daily activity.

The make-up removers traditionally used in the art to remove oil-based make-up comprise a high concentration of oily or fatty substances, particularly vaseline oil, whose function, when applied to the skin, is to dissolve and remove the various fats which may be in make-up products, so as to remove them.

High concentrations of fatty substances may, however, cause irritation to eyelids and create a sensation of heaviness or weight on the face.

Soap and water or mild detergent products especially formulated for use on delicate skin areas, such as the face, may not be effective in removing wax based make-up such as lipstick and mascara. Scrubbing of the skin to remove make- up may be successful but at the cost of damaging the skin.

For a cosmetic composition to be effective as a make-up remover, it is desirable that the composition has a high efficacy in terms of its ability to remove greasy material,

especially greasy make-up compositions such as lipstick, eye shadow or foundation. Additionally, it may be advantageous for the composition to have a high degree of ease of rinsing, in that it should be taken up rapidly by water when rinsing. Oil-based cleansing products such as"cold cream" may clean make-up from the skin but the resultant oil residue is difficult to remove by wiping off or rinsing with water.

Furthermore, it is generally preferred that the make-up removing composition should also have a low degree of irritancy (i. e. , be mild), not only with regard to the skin but in particular with regard to the eyes, as is required, for example, in the removal of make-up from the eyes.

EP 0 213 827 A discloses a non-foaming cleansing mousse forming emulsion packaged in a-pressurised container. The emulsion comprises a concentrate containing specified amounts of a specific non-ionic surfactant, emollient, skin moisturiser and water. A specified amount of a moderately water-soluble propellant is also present. The compositions disclosed in EP 0 213 827 A are substantially free of anionic surfactants and water insoluble propellants and do not require rinsing.

EP 0 541 347 A describes a make-up remover composition comprising specified amounts of a specific non-ionic surfactant and, optionally, an anionic surfactant electrolyte and thickener. EP 0 586 234 A discloses a foaming skin cleansing composition comprising a specific

non-ionic surfactant having a certain HLB value and at least one low irritant anionic surfactant.

EP 0 437 956 A describes a cleansing composition in the form of a mousse comprising a concentrate comprising a specific oil, a non-ionic emulsifier and water together with a propellant.

US 5,334, 387 describes topical compositions containing admixtures of phosphate surfactant mixtures and co- surfactants.

There remains a need for make-up removal compositions that are mild, capable of effectively removing oily and waxy make-up from the skin and/or eyes and which are capable of providing a mousse with acceptable consumer properties such as, for example, creaminess, amount of foam and duration of foam.

Accordingly, the present invention provides an aqueous cosmetic composition suitable for use as a make-up remover comprising: (a) a surfactant system comprising (i) an alkyl sulphate surfactant; (ii) an alkyl phosphate surfactant; (iii) an alkyl succinate surfactant; (iv) an amphoteric surfactant; and (b) a propellant.

In a further aspect, the present invention provides a method of removing make-up, which comprises applying to the skin the composition of the invention in any of the embodiments described herein.

The compositions of the present invention are suitable for topical application to the skin, particularly the face and neck of a user.

The compositions of the present invention may be used as general skin cleansers but they can be particularly suitable for removing waterproof and/or non-waterproof make-up from the skin and/or eyes.

Surprisingly, the cosmetic compositions of the present invention may produce acceptable amounts of mousse foam, even in the presence of oily materials. Moreover, the compositions of the present invention can be mild, with low irritation to the skin, yet can be capable of effectively removing waxy make-up products from the skin and/or face.

Packaged compositions according to the invention may also have a number of advantages. Thus, the combination of the composition packaged as a foamable concentrate in a sealed container having a dispensing means which forms a mousse on dispensing may prevent oxidation and degradation of the composition during storage or standing. It may also provide a means for conveniently dispensing the required amount of the composition from the container. Once dispensed, the

product is more easily manipulated and distributed, compared to a low viscosity liquid.

In preferred embodiments of the present invention, the composition comprises the surfactant system in an amount of from 6% to 80% by weight of the total composition, more preferably from 8% to 50% by weight of the total composition.

Advantageously, the total amount of anionic surfactant (ie, alkyl sulphate, alkyl phosphate and alkyl succinate) in the surfactant system is from 6% to 80% by weight of the total composition, more preferably from 8% to 50% by weight of the total composition.

The amphoteric surfactant in the surfactant system is typically present in an amount of from 0.1% to 20% by weight of the total composition, more preferably from 1% to 10% by weight of the total composition.

Each of the surfactant types (i), (ii), (iii) and (iv) may be present in an amount of from 0. 1% to 20% by weight of the total composition. Preferably, each surfactant type is present in an amount of from 1% to 10% by weight of the total composition.

The term"alkyl"as used herein, includes straight chain and, for alkyl groups containing three or more carbon atoms, branched and also cycloalkyl groups. Examples of straight chain alkyl include methyl, ethyl, propyl, butyl, pentyl and hexyl. Examples of branched alkyl include isopropyl,

isobutyl, and tert-butyl. Examples of cycloalkyl groups include cyclopropyl, cyclobutyl, cyclopentyl and cyclohexyl.

The term"alkylene"is defined similarly to the term"alkyl" but refers to a divalent species with radicals separated by two or more (eg, from two to twelve) carbon atoms linked in a chain.

The term"alkenyl"is defined similarly to the term"alkyl" but the groups contain at least two carbon atoms and one or more carbon-carbon double bond.

The alkyl, alkylene and alkenyl groups may optionally be substituted with, for example, hydroxyl groups, carboxy ester groups, carboxamide groups, carbonyl groups, halogens, eg chlorine and bromine, amino groups and aryl groups, such as phenyl.

In the invention, the term"alkyl sulfate surfactant"may include, for example, a Cg-C1g, more preferably, C12-Cl8 alkyl sulfate or alkyl ether sulfate (including alkyl glyceryl ether sulfates). Particularly suitable examples of alkyl ether sulfates are those having the formula: RO (CH2CH20) nSO3M wherein R is an alkyl or alkenyl group having 8 to 18 carbons, preferably 12 to 18 carbons, n has an average value of greater than 1, preferably greater than 3; and M is a solubilizing cation such as sodium, potassium, ammonium or

substituted ammonium. Ammonium and sodium lauryl ether sulfates are preferred for use in the compositions of the invention. Sodium lauryl ether sulfate such as, for example, sold under the name Texapon N70, which can be obtained commercially from Cognis, is particularly preferred.

The term"alkyl phosphate"includes, for example, C8-C22 alkyl phosphates and phosphates, alkyl phosphate esters and alkoxyl alkyl phosphate esters. The phosphate ester may comprise aryl (EO) X, alkyl or alkyl (EO) x groups. It is particularly preferred if the alkyl phosphate is an alkali metal salt of a 12-13 alkyl phosphate such as, for example, Arlatone MAP 230K-40, which can be obtained commercially from Uniqema. Preferably, the alkyl phosphate salt is a potassium salt.

The term"alkyl succinates"includes, for example, alkyl sulfosuccinates and alkoxylated citrate sulfosuccinates.

Advantageously, the sulfosuccinates may be mono or dialkyl, e. g., C6-C22 sulfosuccinates.

For example, suitable sulfosuccinates may be monoalkyl sulfosuccinates having the formula: R102CCH2CH (SO3M) CO2M ; and amide-MEA sulfosuccinates of the formula R CONHCH2CH202CCH2CH (S03M) C02M ; and

amido-MIPA sulfosuccinates of the formula R 1CONH (CH2) CH (CH3) (S03M) CO2M wherein R ranges from Cg-C22 alkyl and M is a solubilizing cation such as, for example, sodium, potassium or ammonium.

It is, however, particularly preferred if the alkyl succinate is disodium cocamido MIPA (mono iso-propyl amine) sulfosuccinate such as, for example, sold under the name Momamate CPA-40, which can be obtained commercially from Uniqema.

Amphoteric surfactants suitable for use in compositions of the invention include, for example, alkyl betaines, alkyl amidopropyl betaines, alkyl sulphobetaines (sultaines), alkyl glycinates, alkyl carboxyglycinates, alkyl amphopropionates, alkylamphoglycinates, alkyl amidopropyl hydroxysultaines, and acyl glutamates, wherein the alkyl and acyl groups have from 6 to 19 carbon atoms.

The amphoteric surfactants that may be used in this invention include those comprising at least one acid group.

This acid group may be a carboxylic or a sulphonic acid group. The surfactants preferably include quaternary nitrogen and, therefore, are quaternary amido acids. They typically include an alkyl or alkenyl group of 7 to 18 carbon atoms.

Preferably, they comply with an overall structural formula: where R1a is alkyl or alkenyl of 7 to 18 carbon atoms; R2 and R3 are each independently alkyl, hydroxyalkyl or carboxyalkyl of 1 to 3 carbon atoms; n is 2 to 4; m is 0 to 1; x is alkylene of 1 to 3 carbon atoms optionally substituted with hydroxyl, and y is-C02-or-S03- Suitable amphoteric surfactants within the above general formula include simple betaines of formula: and amido betaines of formula:

where m is 2 or 3.

In the formulae R1b and R1c are alkyl or alkenyl of 7 to 18 carbons; and R2b, R2c and R3b and R3c are independently alkyl, hydroxyalkyl or carboxylalkyl of 1 to 3 carbons. R1b and R1c may in particular be a mixture of C12 and C14 alkyl groups derived from coconut so that at least half, preferably at least three quarters of the groups R and R have 10 to 14 carbon atoms. R, R and R and R are preferably methyl.

A further possibility is that the amphoteric surfactant is a sulphobetaine of formula

where m is 2 or 3, or variants of these in which- (CH2) 3S03 is replaced by In the formulae, R1d and R1e are alkyl or alkenyl of 7 to 18 carbons; and R2d, R2e and R3d and R3e are independently alkyl, hydroxyalkyl or carboxylalkyl of 1 to 3 carbons. R and R e may in particular be a mixture of C12 and C14 alkyl groups derived from coconut so that at least half, preferably at least three quarters of the groups R and R have 10 to 14 carbon atoms. R, R and R and R are preferably methyl.

Preferably, the amphoteric surfactant of the invention comprises at least one imidazoline-based or imidazoline derivative surfactant.

By"imidazoline based or imidazoline derivative surfactants" it is meant surfactants which comprise an intermediate imidazoline ring structure during their synthesis. The

imidazoline ring may be opened under the influence of hydrolysing conditions and is generally not present in the final surfactant products.

It is particularly preferred that the imidazoline-based amphoteric surfactant is selected from the group consisting of alkylamphoacetates, alkylamphopropionates and alkyliminopropionates, preferably wherein the alkyl groups have from 6 to 19 carbon atoms.

Specific examples of suitable amphoteric surfactants include cocodimethyl sulphopropyl betaine and preferably lauryl betaine, cocamidopropyl betaine, sodium cocamphopropionate, disodium lauroamphodiacetate, disodium lauroamphodipropionate and sodium lauriminodipropionate.

It is particularly preferred if the amphoteric surfactant comprises cocamidopropyl betaine, such as, for example, as sold under the name Monateric CAB-LC, which can be obtained commercially from Uniqema and/or disodium cocoamphodiacetate such as, for example, as sold under the name Monateric CLV, which can also be obtained commercially from Uniqema.

Suitably, the weight ratio of the total amounts of (i), (ii) and (iii) to the amount of (iv) may be in the range of from 20: 1 to 1: 20, more preferably from 10: 1 to 1: 1.

The aqueous compositions of the invention, which can optionally be in the form of an emulsion, and propellant can be filled together into a pressurised container to provide

the cleansing composition of the invention, which can then be dispensed in the form of a mousse.

The compositions of the invention include an aerosol propellant that serves to expel the other materials from the container, and forms the mousse character in mousse compositions. The aerosol propellant included in compositions of the present invention can be any liquefiable gas conventionally used for aerosol containers.

Examples of suitable propellants include dimethyl ether and hydrocarbon propellants such as propane, n-butane and isobutane, mixtures of these three propellants, such as CAP 30 (ex Calor), hydrofluorocarbons, such as HFA 152a and 134a, chlorofluorocarbons, such as Propellants 11,12, 114 and 22. The propellants may be used singly or admixed.

Mixtures of water insoluble propellants can also be used.

Water insoluble propellants, especially hydrocarbons, are preferred because they form emulsion droplets on agitation and create suitable mousse foam densities.

The amount of the propellant used is governed by normal factors well known in the aerosol art. For mousses the level of propellant is generally up to 30%, preferably from 2% to 30%, most preferably from 3% to 15% by weight based on total weight of the composition. If a propellant such as dimethyl ether includes a vapour pressure suppressant (e. g. trichloroethane or dichloromethane), for weight percentage calculations, the amount of suppressant is included as part of the propellant.

The method of preparing aerosol mousse compositions according to the invention follows conventional aerosol filling procedures. The composition ingredients (not including the propellant) are charged into a suitable pressurisable container, which is sealed and then charged with the propellant according to conventional techniques.

Aerosol hair mousse compositions are emitted from the aerosol container in the form of a foam. The foam is then typically applied to the face with, for example, fingers, a personal cleansing implement such as a sponge or wipe and can be either rinsed off with water or wiped off with, for example, a tissue or other suitable means.

The compositions of the present invention can be formulated as a liquid having a viscosity of from 10 to 2,000 mPas, as measured with a Brookfield RVT viscometer using spindle 3 at 25°C.

The composition may advantageously be packaged in a suitable pressurised container from which it can be dispensed as a mousse. The container is generally fitted with a closure incorporating a valve and an actuator suitable for dispensing a mousse. Suitable containers may be made from any material, especially metal, such as, for example, aluminium or tin plate, plastics and including mixtures, laminates or other combinations of these.

Other anionic surfactants which may be included in compositions of the invention include, for example, aliphatic sulfonates, such as a primary alkane (e. g., C8-C22)

sulfonate, primary alkane (e. g., C8-C22) disulfonate, C8-C22 alkene sulfonate, C8-C22 hydroxyalkane sulfonate or alkyl glyceryl ether sulfonate (AGS), or aromatic sulfonates such as alkyl benzene sulfonate, acyl lactates, and maleates, sulphoacetates, alkyl glucosides and acyl isethionates, preferably the Cs-Cig acyi isethionates, alkyi and acyl taurates, alkyl and acyl sarcosinates and sulfoacetates.

Nonionic, cationic and zwitterionic surfactants may also optionally be used.

Nonionic surfactants include in particular the reaction products of compounds having a hydrophobic group and a reactive hydrogen atom, for example aliphatic alcohols, acids, amides or alkyl phenols with alkylene oxides, especially ethylene oxide either alone or with propylene oxide.

Specific nonionic detergent compounds are alkyl (C6-C22) phenols-ethylene oxide condensates, the condensation products of aliphatic (C8-C18) primary or secondary linear or branched alcohols with ethylene oxide, and products made by condensation of ethylene oxide with the reaction products of propylene oxide and ethylenediamine. Other so-called nonionic detergent compounds include long chain tertiary amine oxides, long chain tertiary phosphine oxides and dialkyl sulphoxides.

The nonionic may also be a sugar amide, such as a polysaccharide amide. Specifically, the surfactant may be one of the lactobionamides described in U. S. Patent No.

Other surfactants which may be used are described in U. S.

Patent No. 3,723, 325 to Parran Jr. and alkyl polysaccharide nonionic surfactants as disclosed in U. S. Patent No.

4,565, 647 to Llenado, both of which are also incorporated into the subject application by reference.

Suitable cationic surfactants that can be incorporated are alkyl substituted quaternary ammonium halide salts e. g. bis (hydrogenated tallow) dimethylammonium chlorides, cetyltrimethyl ammonium bromide, benzalkonium chlorides and dodecylmethylpolyoxyethylene ammonium chloride and amine and imidazoline salts for e. g. primary, secondary and tertiary amine hydrochlorides and imidazoline hydrochlorides.

Suitable zwitterionic surfactants that optionally can be employed are derivatives of aliphatic quaternary ammonium, sulphonium and phosphonium compounds having an aliphatic radical of from 8 to 18 carbon atoms and an aliphatic radical substituted by an anionic water-solubilising group, for instance 3-(N-N-dimethyl-N-hexadecylammonium) propane-1- sulphonate betaine, 3- (dodecylmethyl sulphonium) propane-1- sulphonate betaine and 3- (cetylmethylphosphonium) ethane sulphonate betaine.

The amounts of additional surfactant will generally be in the range of from 0. 01% to 10%, more preferably 0. 1% to 5% by weight of the total composition.

In a preferred embodiment of the present invention, the composition is substantially free of non-ionic surfactants.

By"substantially freen it is meant that the composition contains a non-ionic surfactant in an amount of less than 1% by weight of the total composition, preferably less than 0. 1% by weight, more preferably less than 0.01% by weight of the total composition. Ideally, no non-ionic surfactant is present.

The compositions of the invention can optionally comprise a benefit agent in an amount of from 0. 1% to 40%, preferably from 1% to 20%, more preferably from 2% to 10% by weight of the total composition.

The benefit agent may be a single benefit agent component or it may be a benefit agent compound added via a carrier.

Further, the benefit agent composition may be a mixture of two or more compounds one or all of which may have a beneficial aspect. In addition, the benefit agent itself may act as a carrier for other components one may wish to add to the composition.

The benefit agent can be an"emollient oil"by which is meant a substance which softens the skin (stratum corneum) by increasing into water content and keeping it soft by retarding decrease of water content.

Preferred emollients include : (a) silicone oils, gums and modifications thereof such as linear and cyclic polydimethylsiloxanes ; amino, alkyl, alkylaryl and aryl silicone oils; (b) fats and oils including natural fats and oils such as jojoba, soybean, rice bran, avocado, almond, olive, sesame, persic, castor, coconut, mink oils; cacao fat; beef tallow, lard; hardened oils obtained by hydrogenating the aforementioned oils; and synthetic mono, di and triglycerides such as myristic acid glyceride and 2-ethylhexanoic acid glyceride; (c) waxes such as carnauba, spermaceti, beeswax, lanolin and derivatives thereof ; (d) hydrophobic plant extracts; (e) hydrocarbons such as liquid paraffins, vaseline, microcrystalline wax, ceresin, squalene, pristan and mineral oil; (f) higher fatty acids such as lauric, myristic, palmitic, stearic, behenic, oleic, linoleic, linolenic, lanolic, isostearic and poly unsaturated fatty acids (PUFA); (g) higher alcohols such as lauryl, cetyl, stearyl, oleyl, behenyl, cholesterol and 2-hexadecanol alcohol; (h) esters such as cetyl octanoate, myristyl lactate, cetyl lactate, isopropyl myristate, myristyl myristate, isopropyl palmitate, isopropyl adipate, butyl stearate, decyl oleate, cholesterol isostearate, glycerol monostearate, glycerol

A particularly preferred benefit agent is silicone, preferably silicones having viscosity greater than about 10,000 centipoise at 25°C. The silicone may be a gum and/or it may be a mixture of silicones. One example is polydimethylsiloxane having a viscosity of about 60,000 centistokes at 25°C.

Other particularly preferred emollients include, for example, isopropyl isostearate, such as, for example, sold under the name Prisorine 2021 which may be obtained commercially from Uniqema. The compositions of the invention may also benefit from the introduction of other skin conditioning agents such as, for example, phospholipids. A particularly preferred phospholipid is polysiloxy linoleyl pyrrolidone phospholipid, such as, for example, as sold under the name Arlasilk phospholipid pln and which can be obtained commercially from Uniqema.

A combined surfactant and silicone phospholipid, such as, for example, polysiloxy linoleyl pyrrolidone phospholipid may provide a surfactant functionality which is easier to formulate. In addition, the silicone functionality provides sensorial benefits. The use of a silicone phospholipid may improve the physical and sensorial qualities of the foam.

Preferably, the phospholipid is present in an amount of from 0. 1 to 10% by weight of the total composition, more preferably in an amount of from 1% to 5% by weight of the total composition.

Additional moisturisers for such cosmetic compositions may be chosen from mineral and vegetable oils, hydroxyethylcellulose derivatives, glycerol, glycols, polyhydric alcohols and sorbitol amongst others.

Example 3 Comparative Experiment The compositions of Examples 1 and 2 were compared with a comparative sample, Pond's Tsuru-Tsuru Whipping, a make-up cleansing foam from Japan, to assess their relative make-up removal efficacy.

Procedure and Results The above three samples were evaluated against a long lasting make-up product using the following protocol: Subjects: 10-30 subjects, male and female.

Test materials: Mascara: Revlon Colorstay Lashcolor- Blackest Black Makeup remover products (Compositions of Example 1, Example 2 and Comparative Example) Measurements: Minolta CR-10 Chromameter set to the L*, a*, b* color system Visual grading of the amount of colour cosmetic in the skin using the following scale: 0 = None i = Questionable; trace with spotty coverage

1 = Trace with uniform coverage 2 = Slight with uniform coverage 3 = Moderate with uniform coverage 4 = Heavy with uniform coverage Procedure: 1. Two or three 3.5 x 2.5cm areas are marked on the inner forearm. Four or six sites are marked per subject.

2. The first readings are taken (CLEAN).

3. Colour make-up is applied to the marked area in a manner consistent with its use. Cosmetics are applied in a standardized way to ensure that approximately equal weights of products are transferred and that coverage of the test area is uniform. Make-up is allowed to dry or set for 10 minutes.

Mascara-Spread uniformly, using spatula for even coverage.

4. Twelve minutes after make-up application, the second readings are taken (MAKE-UP).

5. Make-up is removed from each site using the specified test article, rubbing with circular motion for 20 seconds. The cream is removed from the skin using a clean tissue (3 wipes).

6. The final readings are taken (REMOVED).

The product efficacy was calculated using the following formulae: Percent Removed (Chromameter) = <BR> <BR> <BR> <BR> <BR> <BR> V [(LMakeup - LRemoved)@ + (aMakeup - aRemoved)@ + (bMakeup - bRemoved) ------------------------------------------------------------ x 100 <BR> <BR> <BR> 'oo<BR> # [(LMakeup - L Clean)@ + aMakeup - aClean)@ + (bMakeup - bClean)@] Percent Removed (Visual) = (XMakeup - XRemoved) / (XMakeup - XClean) x 100 Product Assignment: An assignment schedule is used to rotate the test materials across the six test sites.

The following table shows the samples tested and the percentage of efficacy to remove mascara (Chromameter measurements and visual scores). The number of panelists was 10 for each sample. Overall Percent Removal Product (Mascara) Chromameter Visual Example 1 87. 4% 77. 3% Example 2 94. 0% 84. 1% Comparative Example (Pond's Tsuru-Tsuru Whipping Make-up 93. 0% 83. 8% Cleansing foam)

The values for make-up removal calculated from the chromameter readings and from a visual evaluation were broadly similar.

The values in the above table show that the compositions of the present invention are effective at removing long lasting make-up products, such as mascara. In addition, the compositions of the present invention performed well compared to a known make-up removing composition. Indeed, the composition of Example 2 was particularly effective at removing mascara.

Also, the compositions of the above examples provide superior make-up removal performance compared to other make- up removal compositions currently on the market.

Example 4 : Mildness and skin irritation tests Procedure and results Subjects : 12, all female.

All subjects evaluated the compositions of Examples 1 and 2 to remove eyelash mascara, following their usual make-up removal routine.

The presentation of the compositions was randomised amongst the subjects who were questioned regarding the performance of the compositions for skin irritation.

The sequential for preference test was processed using Friedman analysis and frequency tables.

The compositions were evaluated on a scale from moderate irritation to non-irritating.

No significant differences were found among the compositions with respect to eye or skin irritation at 95% confidence level.

The compositions of the present invention were found to have comparable mildness to the skin and/or eyes when compared with the subject's usual products for removing make-up from their eyes.
