SUMMARY A new type of beeswax derivative has been developed that is hydro- philic in character. Products rang- ing in degree of water dispersibility have been prepared. These de- rivatives may have two functions in cosmetic formulation they may be used as emulsifiers or, in addition to being used as emulsifiers, they may serve as cosmetic ingredients--i.e., to replace beeswax. These deriva- tives are non-ionic and they possess characteristic advantages over soaps as emulsifiers. Although the non-ionics have been widely used by the cosmetic industry, satisfactory soap-free cold creams have not been prepared. The modified beeswax derivatives per- mit the preparation of soap-free cold creams which have good sta- bility. In combination with other non-ionics, or in soap-type prepara- tions, the beeswax products produce INGREDIENTS Beeswax, white--Will and Baumer Candle Co. Borax--General Chemical Co.
