Food & Nutrition: Staling Inhibitor

GMS 90 (Distilled Monoglyceride) is essential in the baking industry. It forms a complex with the amylose in starch, preventing it from recrystallizing (retrogradation), which significantly slows down the staling of bread and improves the crumb structure

Beauty & Personal Care: Viscosity & Opacity

GMS 40 SE is the "workhorse" of the cosmetic industry. Acts as a primary O/W emulsifier and thickening agent, giving lotions a "pearly" appearance and a smooth, non-greasy spreadability. Ensures that the oil and water phases remain perfectly blended under varying temperatures

Industrial & Plastics: Antistatic Agent

Production of Polyethylene (PE) and Polypropylene (PP) films, GMS is used as an internal antistatic agent. Migrates to the surface of the plastic, forming a thin layer that attracts moisture, which dissipates static charges and prevents films from sticking

Storage Stability

Highly stable. However, high-mono grades (GMS 90) are more prone to caking in humid environments.

Storage Section

Store in a cool, dry place (below 30°C). Keep away from direct sunlight. SE grades should be kept strictly dry to prevent the activation of the self-emulsifying salts.
