Abstract
A water based, viscoelastic composition for use in cosmetic formulations comprising, (a) a mixture of sodium hyalfractions having different molecular weights, (b) protein which is derived from the natural material from which the hyaluronate is obtained, and (c) water. Also disclosed are cosmetic formulations comprising about 0.05-5.0% of the above composition together with an emollient, a sugar alcohol, a neutral or anionic polysaccharide, a preservative, bacteriostatic and fungistatic substance which does not react with or degrade hyaluronic acid, and water.
Claims10
A water based, viscoelastic composition comprising, by weight, (a) a mixture of different sodium hyaluronate fractions, a first such fraction having a molecular weight of about 10,000 to 200,000 and a second fraction having a molecular weight of about 1.times.10.sup.6 to 4.5.times.10.sup.6, the ratio of said fractions being in the range of about 0.3-2:1, (b) about 50 to 400% of protein based on the weight of ingredient (a), said protein being derived from the natural material from which the hyaluronate is obtained, and (c) the balance being water.
