Description: COSMETIC MAKE-UP COMPOSITIONS Field of the Invention The present invention relates to cosmetic make-up compositions and more particularly, to pigmented foundation make-up compositions having improved moisturisation effectiveness, application characteristics, skin feel and appearance, together with colour corrective characteristics. Background of the 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. A foundation composition is also applied to moisturize the skin, to balance the oil level of the skin and to provide protection against the adverse effects of sunlight, wind and the harsh environment. Make-up compositions are generally available in the form of liquid or cream suspensions, emulsions, gels, pressed powders or anhydrous oil and wax compositions. US Patent No. 3,444,291 discloses a method of filling and camouflaging skin cavities by applying a composition which includes 65 to 75 parts by weight of a microcrystalline wax and about 25 to 35 parts of a mineral oil. The composition includes a colourant, preferably a coal tar dye, for example, D &C Red No. 17, which matches the colour of the user's skin. A spreadable, flowable and greaseless cosmetic cover-up composition is taught in US Patent No 4,486,405. That composition is characterized by the presence of a first and a second alkoxylated surfactant present in substantially the same concentration. US Patent No. 4,804,532 recites a facial cosmetic powder which utilizes crystalline silica in much lower concentration than that employed in the then prior art compositions. This powder, used as a blush or a facial coating, is said to be effective in hiding skin wrinkles, lines and pores. The composition is a mixture of a colour phase and a diluent phase. The colour phase is formed by blending crystalline silica with colourants. The resultant colour phase is mixed with the diluent phase, essentially formed from nacreous materials such as talc and mica, to form the composition. The use of a foundation composition which has a significantly high concentration of nacreous material is taught in US Patent No. 3,978,207. This foundation, a pressed powder composition, is characterized by the presence of a nacreous material such as mica and a binder oil which provides a frosted pearl effect, that is, a lustrous look. The colour of this foundation is provided by the nacreous material. US Patent No. 4,659,562 discloses a cosmetic make-up composition which includes, as a binding agent therefore, an intimate mixture of from 5 to 95 weight percent of a mixture of finely divided silica and about 5 to 95 weight percent of finely divided polyethylene fibres. The composition is recited to maintain its uniformity over the areas of the skin to which it is applied. That is, it is said to be "creaseproof. The composition of the '562 patent includes colourant in admixture with nacreous agents. Nakamura et al., Preprints of the XTVth I.F.S.C.C. Congress, Barcelona, 1986, Vol. I, 51-63 (1986) describes a novel make-up composition utilizing spherical silica and polydimethyl siloxane. This combination is recited to provide a foundation which reduces wrinkle visibility to a greater extent than make-up foundations with which it was compared. This reduction in wrinkle visibility is caused by optical blurring enhanced by the novel use of spherical silica and polydimethyl siloxane. US Patent No. 5,143,722 discloses a cosmetic make-up composition comprising water-in-oil emulsions comprising pigment coated with polysiloxane, a silicone phase, a water phase and a polydiorganosiloxane-polyoxyalkylene copolymeric surfactant. Metal oxide coated substrate nacreous pigments are known in the art and are exemplified by titanium dioxide and/or zirconium dioxide coated mica. Such pigments are described in US- A-3, 497,515, US-A- 3,418,146, US-A-3,087,828 and US- A-4,038,099. Depending on the thickness of the metal oxide coating, the pigments can exhibit interference or reflection colours of blue, green, yellow, red, etc. Foundations in the form of water-in-oil emulsions are well known and provide good coverage and good skin feel, wear and appearance. These have, however, not been successful from the viewpoint of colour correction of the skin tone and for reducing skin redness. It would be desirable to provide a cosmetic make-up composition which delivers not only good coverage to the skin but also which serves to reduce any unevenly coloured or red skin tones. Attempts have been made in the past to correct red facial skin tones by application of a green- coloured foundation followed by application of a conventional pigmented foundation. It would be desirable, therefore, to provide a single pigmented foundation composition which delivers both skin colour corrective benefits and good coverage, but does not appear green on the skin. It is accordingly an object of the invention to provide a pigmented make¬ up composition in the form of a water-in-oil emulsion, which exhibits good moisturisation together with good coverage and skin colour corrective benefits. Summary of the Invention According to the present invention there is provided a make-up composition in the form of a water-in-oil or oil-in-water emulsion comprising: a) from about 1% to about 50% by weight of silicone oil selected from volatile silicones, non-volatile silicones and mixtures thereof, b) optionally up to about 30% by weight of humectant, c) from about 0.1 % to about 25% by weight of at least one coated or uncoated iron oxide-type pigment, and d) from about 0.1 % to about 10% by weight of a Tiθ2-coated platelet-type interference pigment material having a Tiθ2 layer thickness of from about 120nm to about 160nm or a whole number multiple thereof. The water-in-oil emulsions of the present invention provide improved colour corrective benefits together with good coverage, skin appearance and superior moisturisation. All levels and ratios are by weight of total composition, unless otherwise indicated. Chain length and degrees of alkoxylation are also specified on a weight average basis. Detailed Description of the Invention The make-up composition according to the present invention comprises a mixture of volatile and/or non- volatile silicones, iron oxide-type pigment, Tiθ2 platelet type interference pigment material and optionally humectant.

The make-up compositions of the present invention can also comprise a paniculate 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 300m2/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 paniculate 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 (CH 2 )nCH 3 . 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 200-3 OOm-2/g.

In the first step, the mixture of components of phase A is stirred for approximately 5 minutes with sheer mixing until homogeneous. With high speed sheer mixing, the materials of phase B are added gradually to A and the batch is mixed for 35 minutes until dispersed. The components of phase C and then phase D are slowly added to the mixture of phases A and B with high shear mixing until dispersed. Silica is added at this point and dispersed through the mixture. The components of phase E are added into the resulting batch which is then heated to 84°C and mixed until dispersed. The vessel is cooled to 45 °C and the premixed phase F is added. The batch is mixed until homogeneous. The mixture is cooled to 30°C and phase G is added. A premix of phase H is made by mixing all the components until completely dissolved. At 30°C the premix of phase H is added sparingly to the batch mixture with high shear, ensuring that there is no excess water on the surface. The mixture is then mixed for 15 minutes. Finally phases I, J, K, and L are added. The resulting make-up composition is ready for packing. The make-up compositions of the Examples exhibit improved moisturisation, application characteristics, skin feel and appearance, together with colour corrective characteristics.
