گلیسرول مونواستئارات SE40

Glycerol Monostearate SE40 (GMS SE40) is a non-ionic surfactant and emulsifying agent widely used in pharmaceuticals, cosmetics, and food products. It acts as an emulsifier, stabilizer, and thickening agent, providing smooth texture and improved consistency in formulations.

🏭⚗️ Production
Glycerol monostearate is produced by esterification of glycerol with stearic acid. The SE40 grade indicates a self-emulsifying form with approximately 40% monostearate content, which allows easier dispersion in aqueous systems. The product is purified, dried, and processed to a fine, free-flowing powder or granules suitable for pharmaceutical and cosmetic applications.

🔬 Properties
GMS SE40 appears as a white to off-white waxy powder or granules. It is soluble in hot water and oils, forming stable emulsions. Chemically, it is a monoester of glycerol and stearic acid, with amphiphilic properties that enable emulsification of oil-in-water and water-in-oil systems. It has good thermal stability and is non-toxic, non-irritant, and compatible with most formulation ingredients.

🧪 Applications
In pharmaceuticals, GMS SE40 is used in creams, ointments, and topical gels as an emulsifier and stabilizer. In cosmetics, it improves texture and stability in lotions, creams, and hair care products. In food formulations, it serves as an emulsifying agent in spreads, confectionery, and bakery products. It is also used in controlled-release formulations to modify release rates of active ingredients.

⚠️ Safety
GMS SE40 is generally regarded as safe for topical, oral, and cosmetic use. Excessive inhalation of the powder should be avoided. It should be stored in a cool, dry place, away from moisture and strong oxidizing agents. Handling should include standard protective measures such as gloves and dust masks in industrial or laboratory settings.
