Description: COSMETIC COMPOSITIONS AND PROCESSES FOR MANUFACTURE THEREOF Field of the Invention The present invention relates to cosmetic make-up compositions and more particularly, to pigmented foundation make-up compositions having improved coverage together with excellent moisturisation effectiveness, application characteristics, skin feel and appearance. The present invention also relates to processes for manufacturing cosmetic make-up compositions which provide a convenient means for shade adjustment of the said compositions. Background of t e Invention A foundation composition can be applied to the face and other parts of the body to even skin tone and texture and to hide pores, imperfections, fine lines and the like. Particularly suitable foundation compositions are available in the form of liquid or cream suspensions, emulsions, and gels. Such compositions are typically made by incorporating a mixture of pigments into a liquid base. The pigments, commonly based on iron oxides, titanium dioxide, or mixtures thereof, are chosen such that they provide desirable skin tones when the product is applied to the skin. The process for incorporating the pigments often requires a milling stage in order to control the pigment dispersion and thus provide smooth and even coverage of the skin. As a consequence of variances in raw materials and processsing, batches of finished product may deviate in colour from the target shade. Routine manufacture usually allows for a final shade adjustment of each liquid foundation batch. Since the pigments used cannot usually straightforwardly be added to the finished product without first pre- wetting them in either the oil or water phase, a common practice is to prepare monochromatic batches of finished product specifically for the purpose of final shade adjustment. The need to prepare these monochromatic batches increases the complexity and cost of the manufacturing process. Quite apart from manufacturing considerations, users of foundation compositions often express dissatisfaction with the degree of coverage of the skin provided by foundations based on conventional pigment systems. Moreover, it is often found that in attempting to improve the amount of coverage by increasing the total pigment level, the naturalness of appearance is adversely affected. It would therefore be desirable to provide a foundation composition containing novel pigment systems which deliver improved coverage and wear without compromising on other properties of the foundation such as skin feel, application characteristics and a natural appearance. It is accordingly an object of this invention to provide a foundation composition in the form of either a water-in-oil or an oil-in-water emulsion, which exhibits improvements in coverage, together with excellent wear characteristics and a natural appearance. It is also an object of this invention to provide a foundation composition which provides improvements in coverage and wear without trade-offs in other areas of foundation performance, especially skin feel and application characteristics. It is a further object of the invention to provide an improved method of manufacturing and shade-matching of colour cosmetic emulsion-form compositions, and, in particular, a method in which the shade can be adjusted to the desired target without the need to use separately prepared monochromatic batches of the compositions. Summary of the Invention According to a first aspect of the invention there is provided a process for manufacturing a colour cosmetic water-in-oil or oil-in-water emulsion composition in which the colour derives from the addition of inorganic or organic pigment, wherein at least a portion of the pigment is made water-dispersible by surface treatment with hydrophilic polymer, and wherein the process comprises adding all or part of the water-dispersible polymer- treated pigment into a pre-formed water-in-oil or oil-in-water emulsion. According to a further aspect of the invention there is provided a colour cosmetic water- in-oil or oil-in-water emulsion composition wherein the aqueous phase contains a water- dispersible pigment and the oil phase contains an oil-dispersible pigment. All levels and ratios are by weight of total composition, unless otherwise indicated. Detailed Description of the invention The compositions of the invention take the form of either water-in-oil or oil-in-water emulsions which contain as essential ingredient a water-dispersible pigment or mixture of pigments. According to one embodiment herein the pigment is a water-dispersible polymer-treated inorganic or organic pigment, more preferably the pigment is a water- dispersible polyester or polyesteramide-treated pigment, especially a water-dispersible polyester-treated pigment. Suitable water-dispersible polyester-treated pigments are those available under the tradename Eastman AQ Treated Pigment (from Eastman Chemical Corporation). The water-dispersible pigment or mixture of pigments is present in an amount of from about 0.1% to about 25%, preferably from about 0.5% to about 15%, and more preferably from about 1 % to about 12% by weight. A preferred water-dispersible polyester or polyester amide for use herein comprises the following repeat units: (a) at least one difunctional dicarboxylic acid, (b) at least one difunctional sulfomonomer containing at least one sulfonate group of the formula: -SO3M wherein M is H, a metal ion, or a nitrogen-contaming basic group, and wherein said sulfonate group is attached directly to an aromatic nucleus and the functional groups of said sulfomonomer are hydroxy, carboxy, amino or a mixture thereof, and (c) at least one glycol or a mixture of a glycol and a diamine having two -NRH groups, the glycol containing two -CH2-OH groups, wherein R is H or an alkyl group of 1 to 4 carbon atoms. Preferably the difunctional sulfomonomer is present at a level of from about 2 to about 25 mole %, based on a total of all acid, hydroxyl and amino equivalents being equal to 200 mole %. The water-dispersible polyester-treated pigment used herein comprises from about 1 % to about 40% , preferably from about 5% to about 30% by weight thereof of polymer. The average particle size of the treated granulated pigment product is typically between 75μm and about lOOOμm, with a more typical average particle size being between about 125/_m and about 500μm, especially between about 150 m to about 300 m. The pigment materials useful in the present invention include water-insoluble, or sparingly water-soluble inorganic and organic pigments, and pearlants commonly used in cosmetics, paints, coatings, and inks, preferably inorganic pigments. Pigment materials suitable herein have a refractive index greater than 1.5, preferably greater than 1.8, more preferably greater than 2. The mean primary particle size of said pigments is preferably greater than 150nm, more preferably greater than 200nm. Typical inorganic pigments include iron oxides of various colors (yellow, red, brown and black), ferric ammonium ferrocyanide (blue), manganese violet, ultramarine blue, chrome oxide (green), titanium dioxide (white) and mixtures of said inorganic pigments. Typical pearlants include mica, bismuth oxychloride and treated mica such as titanated micas. Exemplary pigments useful in the present invention include the C. I. pigment materials, especially polymer-treated inorganic pigments containing iron oxide or titanium dioxide such as, for example, C. I. Pigment Yellow 42, C. I. Pigment Red 101, C. I. Pigment Black 11 and C. I. Pigment White 6. It is noted that pigments having large amounts of ionizable cations are not preferred since they interfere with the water dispersibility of the polymer. The polyesters useful herein for treating pigment or mixture of pigments comprise linear, water-dissipatable polymers having an inherent viscosity of at least 0.1 and preferably at least 0.2 and more preferably at least 0.3 (measured as described hereinbelow) and a glass transition temperature ranging from 25 to 90°C. when the polymers are in the dry state. When the polymers contain 1-25% water of its own weight, the glass transition temperatures ("Tg"s, as measured by differential scanning calorimetry (DSC)) may drop to a lower range usually below 50°C. The polymer compositions useful in this invention are polyesters and polyesteramides described in US-A-3,5446,008, US-A-3,734,874, US-A-3,779,993 and US-A-4,233,196. The polyester or polyesteramide used herein preferably comprise a dicarboxylic acid component, a difunctional sulfomonomer component and a glycol component. The dicarboxylic acid component of the polyester or polyesteramide comprises aliphatic dicarboxylic acids, alicyclic dicarboxylic acids, aromatic dicarboxylic acids, or mixtures of two or more of these acids. Examples of such dicarboxylic acids include succinic, glutaric, adipic, azelaic, sebacic, itaconic, 1,4-cyclohexanedicarboxylic, phthalic, terephthalic and isophthalic. If terephthalic acid is used as the carboxylic acid component of the polyester, superior results are achieved when at least 5 mole percent of one of the other acids is also used. The preferred dicarboxylic acid component for use herein is isophthalic acid. It should be understood that use of the corresponding acid anhydrides, esters, and acid chlorides and other substituted derivatives of these acids is included in the term "dicarboxylic acid". Other suitable acids are disclosed in, for example, US-A-3,779,993. The difunctional sulfo-monomer component of the polyester or polyesteramide may advantageously be a dicarboxylic acid or an ester thereof containing a metal sulfonate group or a glycol containing a metal sulfonate group or a hydroxy acid containing a metal sulfonate group. The metal ion of the sulfonate salt may be Na+ , Li+ , K+ and the like. The resulting polyesters or polyesteramides are less readily dissipated by cold water and more readily dissipated by hot water. It is possible to prepare the polyester or polyesteramide using, for example, as sodium sulfonate salt and later by ion-exchange replace this ion with a different ion, and thus alter the characteristics of the polymer. The difunctional monomer component may also be referred to as a difunctional sulfo-monomer and is further described hereinbelow. Advantageous difunctional sulfo-monomer components are those wherein the sulfonate salt group is attached to an aromatic acid nucleus such as benzene, naphthalene, diphenyl, oxydiphenyl, sulfonyldiphenyl or methylenediphenyl nucleus. Preferred results are obtained through the use of sulfophthalic acid, sulfoterephthalic acid, sulfoisophthalic acid,4-sulfonaphthalene-2,7-dicarboxylic acid, and their esters; metallosulfoaryl sulfonate as described in US-A-3,779,993. Most preferred for use herein is sulfoisophthalic acid. When the sulfonate-containing difunctional monomer is an acid or its ester, the polyester or polyesteramide should contain at least 8 mole percent of said monomer based on total acid content, with more than 10 mole percent giving particularly advantageous results. Total acid content is calculated as the sum of (1) moles of component (a) namely dicarboxylic acids, (2) one-half of the moles of carboxyl-containing compounds of component (d), (3) moles of component (c) which are dicarboxylic acids, and (4) one- half of the moles of component (c) which are monocarboxy-containing compounds. Preferably at least part of the glycol component contains repeating units of a poly(ethylene glycol) of the formula H-(OCH-2-CH2) n -OH wherein n is an integer of 1 to 500, more preferably 2 to about 500. The values of n and the mole percent of poly(ethylene glycol) within the stated range is inversely proportional to the quantity of n within the stated ranges. Thus, when the mole percent is high, the value of n is low. On the other hand, if the mole percent is low, the value of n is high. It is apparent, therefore, that the weight percent (product of mole percent and molecular weight) of the polyethylene glycol is an important consideration because the water dissipatability of the copolyester decreases as the weight percent poly-(ethylene glycol) in the copolyester decreases. For example, if the weight percent of poly(ethylene glycol) is too low, the water dissipatability of the copolyester may be inadequate. Furthermore, the weight percent of poly(ethylene glycol) is preferably adjusted such that it is inversely proportional to the mole percent of the difunctional sulfomonomer because the water dissipatability of the copolyester is a function of both the mole percent sulfomonomer and the weight percent polyethylene glycol. Examples of suitable poly(ethylene glycols) include relatively high molecular weight polyethylene glycols, some of which are available commercially under the designation "Carbowax", a product of Union Carbide. Diethylene glycol is also especially suitable. Other useful glycols for preparing oopolyesters may consist of aliphatic, alicyclic, and aralkyl glycols. Examples of these glycols include ethylene glycol; propylene glycol; 1, 3-propanediol, 2, 4-dimethyl-2-ethylhexane-l,3-diol; 2,2-dimethyl-l,3-propanediol; 2- ethyl-2-butyl-l,3-propanediol; 2-ethyl-2-isobutyl-l,3-propanediol; 1,3-butanediol; 1,4- butanediol; 1,5-pentanediol; 1,6-hexanediol; 2,2,4-trimethyl-l,6-hexanediol; thiodiethanol; 1,2-cyclohexanedimethanol; 1,3-cyclohexanedimethanol; 1,4- cyclohexanedimethanol; 2,2,4,4-tetramethyl-l,3-cyclobutanediol; p-xylylenediol. A preferred polyester herein is a diglycol cyclohexanedimethanol isophthalates sulfoisophthalates copolymer. Particularly superior results are achieved when the difunctional sulfo-monomer component is 5-sodiosulfoisophthalic acid or its esters and the glycol is a mixture of ethylene glycol or 1,4-cyclohexanedimethanol with diethylene glycol. Other suitable water-dispersible pigments for incorporation in the compositions of the invention include hydrophilic pigments based on, for example, titanium dioxide and iron oxides. In a preferred aspect of the invention the compositions herein also contain an oil- dispersible pigment or mixture of pigments in a level preferably from about 0.1 % to about 25%, more preferably from about 0.5% to about 15% and especially from about 1 % to about 12%. by weight. Suitable oil-dispersible pigments for use herein can be inorganic and/or organic. Examples of suitable pigments include iron oxides of various colors (yellow, red, brown and black), ferric ammonium ferrocyanide (blue), manganese violet, ultramarine blue, chrome oxide (green), titanium dioxide (white) and mixtures of said inorganic pigments. A mixture of pigments will normally be used. Also suitable for use herein are coated pigments. The pigments can be treated with compounds such as perfluoroethers, amino acids, silicones, lecithin and ester oils, more preferably with silicones (polysiloxanes) such as polymethyl hydrogen siloxane as described in EP-A-0271925. The compositions herein take the form of water-in-oil or oil-in-water emulsions in which the oil phase can include one or more silicone oil components.

Lower viscosity non-volatile silicone conditioning agents, however, can also be used. Viscosity can be measured by means of a glass capillary viscometer as set forth in Dow Coming Corporate Test Method CTM0004, July 20, 1970. Suitable non-volatile silicone fluids for use herein include polyalkyl siloxanes, polyaryl siloxanes, polyalkylaryl siloxanes, polysiloxanes with amino functional substitutions, polyether siloxane copolymers, and mixtures thereof. The siloxanes useful in the present invention may be endcapped with any number of moieties, including, for example, methyl, hydroxyl, ethylene oxide, propylene oxide, amino and carboxyl. However, other silicone fluids having skin conditioning properties may be used. The non-volatile polyalkyl siloxane fluids that may be used include, for example, polydimethylsiloxanes. These siloxanes are available, for example, from the General Electric Company as a Viscasil (RTM) series and from Dow Corning as the Dow Corning 200 series.

A preferred aluminium-magnesium-hydroxystearate gelling agent is commercially available from Guilini Chemie GmbH under the tradename Gilugel Sil 5. (CTFA designation: Cyclomethicone pentamer (and) Aluminium-Magnesium-Hydroxy-Stearate). Gilugel Sil 5 is a lipogel comprising about 80% cyclomethicone pentamer and about 20% alumimum-magnesium-hydroxy-stearate. It is particularly valuable in the compositions of the present invention from the viewpoint of improving emulsion stability, spreadability, rheological characteristics and skin feel, and for reducing undesirable tack, shine and greasiness characteristics associated with humectants such as glycerin. The balance of the composition of the present invention comprises deionized water. The composition preferably comprises from about 15% to about 95%, more preferably from about 20% to about 60% by weight of the oil phase, and from about 5% to about 85%, more preferably from about 40% to about 80% by weight of the water phase. The make-up compositions of the present invention can also comprise a particulate cross- linked hydrophobic acrylate or methacrylate copolymer. This copolymer is particularly valuable for reducing shine and controlling oil while helping to provide effective moisturization benefits. The cross-linked hydrophobic polymer is preferably in the form of a copolymer lattice with at least one active ingredient dispersed uniformly throughout and entrapped within the copolymer lattice. Alternatively, the hydrophobic polymer can take the form of a porous particle having a surface area (N2-BET) in the range from about 50 to 500, preferably 100 to 300m 2 /g and having the active ingredient absorbed therein. The cross-linked hydrophobic polymer when used herein is in an amount of from about 0.1 % to about 10%, preferably from about 0.3-3% by weight and is preferably incorporated in the external silicone-containing oil phase. The active ingredient can be one or more or a mixture of skin compatible oils, skin compatible humectants, emollients, moisturizing agents and sunscreens. The polymer material is in the form of a powder, the powder being a combined system of particles. The system of powder particles forms a lattice which includes unit particles of less than about one micron in average diameter, agglomerates of fused unit particles of sized in the range of about 20 to 100 microns in average diameter and aggregates of clusters of fused agglomerates of sizes in the range of about 200 to 1,200 microns in average diameter. The powder material of the present invention which can be employed as the carrier for the active ingredient can be broadly described as a cross-linked "post absorbed" hydrophobic polymer lattice. The powder preferably has entrapped and dispersed therein, an active which may be in the form of a solid, liquid or gas. The lattice is in particulate form and constitutes free flowing discrete solid particles when loaded with the active material. The lattice may contain a predetermined quantity of the active material. The polymer has the structural formula: where the ratio of x to y is 80:20, R' is -CH2CH2- and R" is -(CH2)nCH3. The hydrophobic polymer is a highly crosslinked polymer, more particularly a highly cross-linked polymethacrylate copolymer. The material is manufactured by the Dow Corning Corporation, Midland. Michigan, USA, and sold under the trademark POLYTRAP (RTM) . It is an ultralight free-flowing white powder and the particles are capable of absorbing high levels of lipophilic liquids and some hydrophilic liquids while at the same time maintaining a free-flowing powder character. The powder structure consists of a lattice of unit particles less than one micron that are fused into agglomerates of 20 to 100 microns and the agglomerates are loosely clustered into macro-particles or aggregates of about 200 to about 1200 micron size. The polymer powder is capable of containing as much as four times its weight of fluids, emulsions, dispersions or melted solids. Adsorption of actives onto the polymer powder can be accomplished using a stainless steel mixing bowl and a spoon, wherein the active is added to the powder and the spoon is used to gently fold the active into the polymer powder. Low viscosity fluids may be adsorbed by addition of the fluids to a sealable vessel containing the polymer and then tumbling the materials until a consistency is achieved. More elaborate blending equipment such as ribbon or twin cone blenders can also be employed. The preferred active ingredient for use herein is glycerine. Preferably, the weight ratio of humectant : carrier is from about 1:4 to about 3:1. Also suitable as a highly cross-linked polymethacrylate copolymer is Microsponges 5647. This takes the form of generally spherical particles of cross-linked hydrophobic polymer having a pore size of from about 0.01 to about 0.05μm and a surface area of 200-300m2/g. Again, it is preferably loaded with humectant in the levels described above. The compositions of the invention can also contain a hydrophilic gelling agent at a level preferably from about 0.01 % to about 10%, more preferably from about 0.02% to about 2%, and especially from about 0.02% to about 0.5%. The gelling agent preferably has a viscosity (1 % aqueous solution, 20°C, Brookfield RVT) of at least about 4000 mPa.s, more preferably at least about 10,000 mPa.s and especially at least 50,000 mPa.s.

In the first step, the mixture of components of phase B is stirred with shear mixing until homogeneous. With slow speed shear mixing at 65-75 °C, the materials of phase C are admixed individually in order as given in the formulations. The components of phase A are mixed until dispersed. The ingredients of phase K are then added to phase A with high shear mixing.. The magnesium alumniium silicate of phase F is prehydrated for at least 30 minutes at 50°C and is then added to the aqueous phase C and thoroughly dispersed therein. The deionised water / propylene glycol (or glycerine) / xanthan gum slurry of phase G is added to heated aqueous phase C at 65-67°C and phase B is slowly added to phase C. Stirring is continued until homogeneous, while maintaining a temperature of 65-67°C. Component D is then added to the resulting mixture with stirring. The components of F and G are added to the mixture with slow stirring for 5 minutes until homogeneous. Then component E is added to the mixture with slow stirring until _ _γnτn1_ _'->1v inrnττv .rat- _ι The resulting oil phase of components A and K is then added to the water phase of components B, C, D, E, F and G and agitated via stirring to emulsify the mixture at a temperature of about 65-67temperature of 65-67°C. The resulting mixture is cooled down. At about 35 °C, the Lubrasil of phase H is added to the resulting batch and mixed until homogeneous. At about 35 °C, the silicone mixture of phase I is added to the resulting batch. The resulting mixture is agitated with low-speed mixing until a gel-like consistency is obtained, generally within about 1-2 minutes. At 30°C, the perfume oil and essential oils of phase L are added and then the components of phase M are added. The resulting make-up composition is ready for packing. The make-up compositions of the Examples exhibit improved coverage and wear, with excellent moistunsation, spreadability, product stability and skin-feel, reduced shine and tackiness and a uniform coverage giving a natural skin appearance. The process is repeated for each of the examples above, with the exception that 10% of the total amount of each of polymer pigments 1, 2 and 3 is reserved for addition as a final step. Before packing, the colour of the make-up composition is spectroscopically compared to the desired target and the reserved amounts of the polymer pigments are dispersed as necessary into the make-up composition using low-shear mixing until the desired colour target is met. The shade-matching process of the Examples provides a method in which the shade of the finished product can be adjusted to the desired target in a convenient manner without the need to use separately prepared monochromatic batches of the finished compositions.
