Ethylene Glycol Distearate CAS# 627-83-8

Glycol distearate, likewise known as ethylene glycol distearate, is a chemical commonly used as an aesthetic moisturizer. It is a diester of ethylene glycol and also stearic acid. Used as a pearlescent representative in cosmetics to create a pearlescent sheen, such as shower gels. It can additionally be utilized as a lipophilic emulsifier. Usually used in combination with ethylene glycol monostearate (EGMS, ethylene glycol stearate).

Ethylene glycol distearate is synthesized from ethylene glycol and stearate. The response temperature of the standard synthesis procedure is high, generally between (150 ～ 210 ° C). In order to remove the water produced by the reaction, steps such as nitrogen circulation, minimized pressure or azeotropic dehydration are called for. Due to the high reaction temperature, serious carbonization and also deep color of the item, extra decolorization procedure is required. There are studies using p-toluenesulfonic acid as well as phosphorous acid (molar ratio 1:1) as a composite driver (hereinafter described as composite stimulant) for esterification, as well as the 3 factors of catalyst usage, reaction temperature level, and response time are experimentally researched. A brand-new synthesis procedure of ethylene glycol distearate was developed.
