Glycerol Monopalmitate (GMP)

Overview

Glycerol Monopalmitate (GMP), also known as Glyceryl Monopalmitate or Monopalmitin (CAS No. 555-44-2, INCI: Glyceryl Palmitate), is a premium monoglyceride derived from the esterification of high-purity glycerol and palmitic acid. As a critical fatty acid ester, GMP is renowned for its exceptional performance as an emulsifier and stabilizer, playing a crucial role in enhancing the texture, stability, and shelf-life of a diverse range of industrial products. Its unique amphiphilic structure, featuring both hydrophilic hydroxyl groups and a lipophilic palmitic acid chain, positions it as an indispensable ingredient across the food, pharmaceutical, and cosmetic sectors.

At CanCastor, our GMP is manufactured under stringent quality controls, ensuring a consistent product that meets the exacting demands of our global clientele. Leveraging advanced esterification techniques, we produce high-purity GMP that complies with leading international standards, including USP, BP, and E-number (E471) guidelines for food applications. Our commitment to traceable sourcing and sustainable manufacturing practices provides our partners with a trustworthy and high-performing ingredient, essential for formulating stable emulsions and optimizing product performance.

Understanding the critical role of ingredient integrity, CanCastor's Glycerol Monopalmitate offers a reliable solution for formulators seeking to achieve superior product consistency, improved rheology, and extended shelf stability.
