An emulsion contains a saccharide siloxane copolymer as an emulsifier. The emulsion is useful in formulating personal care products.

Emulsions containing saccharide siloxane copolymer emulsifiers and methods for their preparation and use

A novel saccharide siloxane copolymer is useful in personal care compositions. The saccharide siloxane copolymer may be used as a universal emulsifier to prepare low odor emulsions for personal care applications.
