Description
Ethylene Glycol Monostearate (EGMS, CAS 111-60-4) is a monoester derived from ethylene glycol and stearic acid. It is commercially available under trade names including Cerasynt M, Ivorit, Monthybase, and S 151. It carries no E-code designation and is classified under HS code 29189900.
In personal care formulations, EGMS functions as an opacifier and pearlising agent in shampoos and body washes, producing a characteristic lustre by forming crystalline platelet structures within the product matrix. In plastics processing, it acts as a plasticiser and internal lubricant, reducing melt viscosity and improving surface finish in polymer compounds.
EGMS is supplied in bead or flake form and is available in cosmetic, food-grade (FCC), and pharmaceutical-grade (Ph.Eur.) specifications to suit different regulatory requirements. It is fully registered under REACH. Procurement teams should confirm grade suitability against application-specific compliance frameworks prior to ordering.
