Glyceryl behenate

Glyceryl behenate (CAS 77538-19-3) is a mono-, di-, and triglyceride ester of behenic acid used as a lipid-based excipient. Also marketed as Compritol 888 ATO.

Where is Glyceryl behenate used?

• Pharmaceutical tablets and capsules: sustained-release matrix former and lubricant
• Hot-melt extrusion and direct compression: improves flow and reduces tablet sticking
• Cosmetics: thickens and stabilizes emulsions in creams, lipsticks, and stick-format products
• Food: fat-based coatings and confectionery fillings, modifying crystallization behavior and improving shelf stability
• It serves as a functional emulsifier in pharmaceutical, food, and personal care manufacturing.

Good to know: Its high melting point makes it suitable for solid-form processing and controlled-release matrix systems. Pharmaceutical-grade material is available to specifications aligned with Ph. Eur. and NF monographs.
