Glycol distearate may be produced via the esterification of stearic acid (or its esters) with ethylene glycol. It can also be produced by a reaction of stearic acid with ethylene oxide.[2]
Applicationsedit
When forced to crystalize as thin platelets glycol distearate can give liquids and gels a pearlescent appearance.[3] 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.
