Product Application of Glyceryl Monostearate CAS#31566-31-1
Glyceryl monostearate is an effective emulsifier with broad applications. As a food additive, it is most commonly used in bread, biscuits, and pastries, as well as in cream, butter, and ice cream production. In the pharmaceutical field, it serves as an excipient in neutral ointment formulations. In personal care products, it is used in face creams, ice creams, and clam oil preparations. Additionally, it functions as a solvent for oils and waxes, a hygroscopic powder protectant, and an opacifying agent.
Glyceryl fatty acid esters, produced from the reaction of glycerol with fatty acids, include monoesters, diesters, and triesters. Triesters, being fats and oils, have no emulsifying ability. Typically, a mixture of monoesters and diesters is used, or a product containing approximately 90% monoesters can be obtained through distillation and purification. Fatty acids such as stearic acid, palmitic acid, myristic acid, oleic acid, and linoleic acid may be used, with stearic acid commonly being the main component in most formulations.
