Lipid vesicles which remain stable at high temperatures are disclosed. The vesicles contain as a component of their lipid bilayers at least one ethoxylated alcohol having a linear C20-C50 carbon chain. Also disclosed is a method of making the vesicles. The lipid vesicles are useful in forming cosmetic and dermatologic preparations, such as lipstick, which are processed at high temperatures (e.g., at 80 °C or above) during manufacture.
