Description
Glyceryl monooleate (CAS 111-03-5), also known as monoolein or 1-monoolein, is a monoglyceride ester formed from glycerol and oleic acid. It carries the molecular formula C21H40O4 and is registered under EC 203-827-7. No E-code designation applies to this ingredient.
In personal care formulations, glyceryl monooleate functions as an emulsifier and skin conditioner by reducing interfacial tension between oil and water phases, enabling stable cream and lotion systems. In food and nutritional applications, it acts as an emulsification aid in fat-based matrices, improving texture and homogeneity in processed food products.
Glyceryl monooleate is supplied as a solid and is available in cosmetic and food-grade specifications. It falls under REACH registration requirements within the EU and is subject to standard cosmetic ingredient compliance under EC Regulation 1223/2009. HS code 29161500 applies for import and export classification purposes.
