Arlacel™ 165 is an acid-stable self-emulsifying glycerol monostearate. The primary use for this product in both versions is as an emulsifier for creams and lotions that are rich in non-polar oils and waxes. Because these are nonionic emulsifiers, they will tolerate the addition of acidic actives and salts. In addition, emulsions made with them can be pH adjusted to between 4.5 and as high as 9. Other known functions for Arlacel™ 165 products include their use as opacifiers in clear cleansing systems (2 to 5%), emulsifiers in anhydrous cream bases (5 to 25%), wetting agents for antiperspirant salts in sticks (2 to 5%) and as dispersants for unique bath oil products.
