Abstract
Spontaneously formed highly stable clear water-in-oil microemulsions containing only small amounts of water can be prepared by combining and simply hand shaking (i) 0.1 to 9 percent by weight of water; (ii) greater than 80 percent by weight of a volatile cyclic alkyl siloxane or volatile linear alkyl siloxane; and (iii) 3 to 10 percent by weight of certain silicone polyether surfactants. The microemulsions are useful in personal care applications.
