Glycol distearate is the diester of stearic acid and ethylene glycol. It is mostly commonly encountered in personal care products and cosmetics where it is used to produce pearlescent effects as well as a moisturizer.
When forced to crystalize as thin platelets glycol distearate can give liquids and gels a pearlescent appearance. This is often used by the producers of personal care products (e.g. shower gel) to increase the visual appeal of their products. It may also act as a skin moisturizer.
Glycol distearate is also commonly used as an embedding agent in microscopy.
