Distilled Mono Glycerides

Overview

Distilled Mono Glycerides (DMG), specifically known by the INCI name Glyceryl Monostearate (CAS No. 123-94-4 for common variants like GMS 40/60), are highly versatile and widely utilized emulsifiers, crucial across numerous industrial sectors, particularly in food, pharmaceuticals, and plastics. Produced through the esterification of high-purity glycerol with natural fatty acids (typically derived from sustainable sources such as palm, soy, or rapeseed oil), DMG undergoes a meticulous distillation process to achieve a minimum monoester content, usually exceeding 90%. This purification ensures superior emulsification efficiency and reduced impurities, meeting the stringent requirements of regulatory bodies like the FDA (Food and Drug Administration) and complying with global pharmacopoeia standards such as USP (United States Pharmacopeia), BP (British Pharmacopoeia), and EP (European Pharmacopoeia) for specific grades.

As a non-ionic surfactant, DMG functions by reducing interfacial tension between immiscible phases, allowing for the formation and stabilization of emulsions (e.g., oil-in-water or water-in-oil). This makes it indispensable in achieving desired texture, consistency, shelf-life, and processability in a vast array of products. CanCastor prides itself on supplying Distilled Mono Glycerides that adhere to the highest standards of quality and purity, with full traceability and certification under ISO 9001 and often cGMP (current Good Manufacturing Practices) for specialized applications. Our commitment to REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) compliance ensures responsible chemical management and safety across our supply chain.
