Abstract
Colour cosmetic water-in-oil or oil-in-water emulsion compositions wherein the aqueous phase contains a water-dispersible pigment and the oil phase contains an oil-dispersible pigment. The compositions provide improved coverage and wear, with excellent moisturisation, spreadability, product stability and skin-feel, reduced shine and tackiness.
Claims8
A color cosmetic water-in-oil or oil-in-water emulsion wherein the aqueous phase contains from about 0.1% to about 25% by weight of the emulsion of a water dispersible pigment selected from the group consisting of iron oxide and titanium dioxide pigment and the pigment is surface treated with diglycol cyclohexanedimethanol isophthalates and sulfoisophthalates copolymer and the oil phase contains from about 0.1% to about 25% by weight of the emulsion of an oil-dispersible pigment.
A process for manufacturing a color cosmetic water-in-oil or oil-in-water emulsion composition in which the color derives from the addition of titanium dioxide or iron oxide pigment and wherein at least a portion of the pigment is made water-dispersible by surface treatment with a diglycol cyclohexanedimethanol isophthalates and sulfoisophthalates copolymer, which 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.
