主权项

1. A cosmetic composition comprising whey protein micelles consisting essentially of spherical agglomerates of denatured whey protein in an amount effective to act as an abrasive medium for abrading skin, at least 80% of the whey protein micelles have a size smaller than 1 micron, and the whey protein micelles have an average size in the range of 100nm to 900nm, wherein the whey protein micelles are obtainable by treating a demineralized aqueous solution of native whey protein either by (i) adjusting the pH of the solution to between 3.5 and 9 or by (ii) adjusting the ionic strength of the solution while keeping the pH constant; and then by heating the solution with the adjusted pH or ionic strength to a temperature of about 70° C. to 95° C. for a time period between 12 to 25 minutes.
