Glycol distearate


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.

Synthesis

Glycol distearate may be produced via the esterification of stearic acid with ethylene glycol. It can also be produced by a reaction of stearic acid with ethylene oxide.

Applications

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 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.
