Glyceryl monostearate

Glyceryl monostearate (CAS 31566-31-1 ), commonly known as GMS or Monostearin, is a monoglyceride ester used across food, cosmetic, and industrial manufacturing. It functions primarily as an emulsifier and rheology modifier.

This versatile chemical enables stable blending of oil and water phases in complex formulations. In food manufacturing, it controls starch retrogradation in baked goods and improves texture consistency in margarine and ice cream.

It is also utilized in pasta products to maintain structural integrity. Personal care formulators use it to stabilize oil-in-water emulsions in creams and lotions, contributing to a smooth, non-greasy skin feel.

Pharmaceutical manufacturers incorporate this ingredient as a matrix former in sustained-release tablet formulations. It also serves as a plasticizer in film coatings to ensure uniform application and durability.

In plastics processing, it acts as an internal lubricant and antistatic agent. This reduces friction during extrusion and improves the surface finish in various polyolefin applications across the industrial sector.

The material is supplied as white to off-white flakes, beads, or powder depending on grade. Food-grade material is available to FCC specifications to ensure safety and compliance for human consumption.

Pharmaceutical-grade product is supplied to USP and Ph. Eur. standards for medical applications. Technical-grade material is available for polymer and industrial applications where specific compliance is not required.
