Synopsis The viscosity of cosmetic emulsions is of great practical importance and related to their skin feel. To achieve a desirable and constant viscosity is not an easy task because numerous factors must be considered. Based on theoretical considerations a new surfactant, steareth‐5‐stearate, has been developed. It can be shown that its use, together with a second more hydrophilic surfactant, results in flowable emulsions, the viscosity of which remain stable under normal conditions.
