ABSTRACT:
Stable water-in-oil emulsions useful as vehicles for cosmetics or for therapeutic compositions to be topically applied are disclosed. The emulsions utilize a concentration of from 0.2 to 2% by weight of magnesium oxide or magnesium hydroxide as a stabilizing agent. The stabilizing agent may be admixed with either the oil or the aqueous phase, and use thereof will permit incorporating up to 70% water in the total composition without loss of stability during either prolonged storage, or exposure to freezing and thawing.
