Nonaqueous Emulsions: History and Current Specialized Applications

Until the mid-1970s, practical applications for nonaqueous emulsions in personal care were almost nonexistent due to formulation difficulties and inelegant properties. However, beginning in the early 1980s, specialized nonaqueous emulsions have attracted technical interest as potential vehicles and delivery systems for personal care and cosmetic products. The reason for this transition has been the development and availability of a broad range of silicone-based emulsifiers, silicone polymers and other polymeric emulsifiers. These materials have enabled the use of nonaqueous emulsions as aesthetic vehicles and delivery systems for a range of distinctive cosmetic and personal care products. This article will briefly review their history and evolution into current-day specialized applications.
