Polyglycerol Esters of Fatty Acids (PGE)

Overview

Polyglycerol Esters of Fatty Acids (PGE) represent a class of highly versatile non-ionic emulsifiers derived from polyglycerol and various fatty acids. These compounds are renowned for their amphiphilic structure, possessing both hydrophilic (water-loving) polyglycerol chains and lipophilic (oil-loving) fatty acid moieties. This unique composition grants PGEs exceptional surface-active properties, making them indispensable in stabilizing oil-in-water and water-in-oil emulsions across diverse industrial sectors. CanCastor’s comprehensive portfolio of PGEs is meticulously engineered to deliver superior emulsification, dispersion, and solubilization capabilities, meeting the stringent demands of global manufacturers.

Our commitment to quality ensures that each batch of PGE conforms to the highest international standards, including USP (United States Pharmacopeia), BP (British Pharmacopoeia), Codex Alimentarius, and relevant EU Regulations (e.g., EU 1333/2008 for food additives). We adhere strictly to REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulations for European markets and FDA (Food and Drug Administration) guidelines for applications in the United States. Sourced from responsibly managed raw materials, CanCastor's PGE products exemplify our dedication to both performance excellence and sustainable industrial practices.

While the specific INCI names vary depending on the degree of polymerization of glycerol and the nature of the fatty acid (e.g., Polyglyceryl-3 Stearate (CAS 125194-40-7), Polyglyceryl-10 Oleate (CAS 11094-60-3)), the foundational chemistry provides a robust platform for customized functional attributes. These tailor-made properties, particularly HLB (Hydrophilic-Lipophilic Balance) values ranging from 2 to 16+, allow formulators unparalleled flexibility in achieving desired emulsion stability and sensory profiles.
