Abstract

A dispersion for carrying at least one water-soluble material or water-dispersible material (especially ascorbic acid, Vitamin C) in a relatively stable form is described, the dispersion comprising an oil phase containing particles comprising water-soluble polymer, water-soluble material or water-dispersible material (ascorbic acid), and water. The dispersion preferably comprises particles which have number average diameter dimensions of less than 2 microns, more preferably less than 1 micron. The dispersion may comprise oil components such as, for example only, a mineral oil, silicone oil, or cosmetic oil. A method of forming a dispersion of solid particles which comprise water-soluble material or water-dispersible material (e.g., ascorbic acid) in a water-soluble polymer may comprise the steps of: a) forming a first solution of the water-soluble material or water-dispersible material (ascorbic acid), water and a water-soluble polymer, b) mixing the first solution with a second solution of a water in a surface active agent having an HLB of less than 12 or less than 10 and oil, c) dispersing the first solution and the second solution to form a mixture of the first solution and second solution, and d) cooling the mixture, solidifying the first solution to form particles dispersed in said oil. This method may have the emulsifying done at a temperature above 40.degree. C., preferably above 50.degree. C., more preferably above 55.degree. C.
