Abstract
ABSTRACT OF THE DISLCOSURE
A skin-care product is disclosed which comprises an unpigmented oil-in-water (or water-in-oil) emulsion containing from 60-90% by weight of water and having dispersed therein from 3 to 10% by weight of substantially spherical synthetic polymer or copolymer particles having an average particle size in the range 5 to 15 microns.

Description
~ 99644 This invention relates to a skin-care product of cream-like or lotion consistency, having a high water content and containing tiny polymer particles. The product may be used as a moisturising cream orlotion and has the advantage of leaving the skin with a smooth feel.
Moisturising creams and lotions are widely u~sed as skin cosmetics. They are generally unpigmented perfumed oil-in-water emulsions (or, less commonly, water-in-oil emulsions~ with a relatively high water content of from about 60-9~ by weight. Such creams are absorbed by the upper layers of skin cells, swelling them to some extent, but otherwise leaving essentially no residual effect on the skin other than a slight perfume. They differ from so-called vanishing creams in that they contain essentially no free fatty acid.
Powder products have traditionally been used for skin smoothing purposes, the powder filling pores and fine wrinkles on the skin surface. With the advent of polymer technology, proposals were made to substitute polymer particles for the powders, such as talc, used in these products.
British Specifications 774029, 818425, 1059970, 1093108, 1141994 and 1202796 all refer to the possible use of polymer particles in cosmetics.
During the course of our investigations into the use of polymer particles in moisturising creams or lotions we found that spherical or substantially sphexical particles l`Q9~644 in the range 5 to 15 microns could be incorporated in amounts from about 3% to about 10~ by weight of the cream or lotion without adversely affecting the stability and other desirable properties. Moreover, despite the very small amount of polymer present, the resulting product rendered the skin particularly smool:h and silky.
Accordingly, the present invention provides a skin-care product comprising an unpigmented oil-in-water (or water-in-oil) emulsion containing from 60-90% water by weight of emulsion and having dispersed therein from 3 to 10% by weight of substantially spherical synthetic polymer or copolymer particles having an average particle size in the range 5 to 15 microns, the oil being a non-w latile oil.
As used herein the term non-volatile oil means an oil which, when applied as a thin film on a surface maintained at 37C does not evaporate to an extent greater than 10% by weight of the applied quantity in a period of 3 hours.
Preferably the product should contain a perfume, and preferably there should be substantially no free fatty acid present.
Usually the product will contain from 3 to 5% by weight of the polymer or copolymer particles.
Preferably the polymer or copolymer particles shall have an ~0 average size of from 5 to 7 microns.
Preferably, substantially none of the polymer or copolymer particles should exceed about 50 microns, and best results are achieved when there are substantially no particles of a size greater than 15 microns.
r~ ~
~99644 The polymer or copolymer particles should preferably not swell to any great extent in water or the oil used in the product.
Within thislimitation cross-linked polystyrene or polymethyl-methacrylate microspheres would be suitable. However/ the preferred polymer is polyethylene.
