coemulsifiers
Coemulsifiers are substances used in emulsion systems to assist primary emulsifiers in stabilizing mixtures of immiscible liquids. They are called coemulsifiers or co-emulsifiers and are commonly used in cosmetics, pharmaceuticals, and food products to enhance stability, texture, and performance of emulsions such as creams and lotions.
Coemulsifiers work by accompanying the main emulsifier at the oil–water interface, helping to form a more cohesive
Types of coemulsifiers include fatty alcohols, glyceryl esters, and other amphiphilic additives that are compatible with
In topical cosmetic emulsions, coemulsifiers help achieve stable water-in-oil or oil-in-water creams with desirable texture. They
Formulators consider compatibility with the primary emulsifier, desired rheology, pH and ionic conditions, regulatory status, and
