Surface modification of kaolin

摘要

The invention is directed to a kaolin that has the surface modified by reaction with specific silicone compounds. The reaction of these materials result in a kaolin that is (a) less dusty when handled, (b) more flowable, (c) has better dispersibility in oils and in emulsion, resulting in less whitening when applied to skin and improved waterproofing when applied to skin, (d) has better stability in emulsions when dispersed in oils because of the durability of the surface treatment.
