Glyceryl Monooleate

CAS: 111-03-5

Overview

Glyceryl Monooleate (CAS 111-03-5 ), commonly abbreviated as GMO, is a monoglyceride ester used as an emulsifier and humectant across food, cosmetic, and industrial formulations.

Recognized under FEMA 2526 , it functions by stabilizing oil-water interfaces and retaining moisture in finished products. In food manufacturing, GMO is used to improve texture and shelf life.

It is frequently utilized in baked goods, margarine, and dairy-based products by preventing fat separation and starch retrogradation. Cosmetic formulators incorporate it into creams, lotions, and hair conditioners.

In these personal care applications, it supports emulsion stability and delivers a smooth, moisturizing skin feel. As a flavoring agent, it appears in systems where its oleic acid profile contributes to creamy taste profiles.

In pharmaceutical and nutraceutical applications, it acts as an excipient and solubilizer in lipid-based drug delivery systems and softgel formulations. It is supplied as a pale yellow to amber liquid or semi-solid.

The physical state depends on temperature and purity grade. It is available in food-grade and technical-grade specifications, with food-grade material meeting FCC standards for safety and quality.

Minimum monoglyceride content typically ranges from 40% to 90%+ depending on the grade. High-purity distilled grades are available for pharmaceutical applications requiring specific chemical profiles.
