Swapnroop Pharma manufactures and supplies Polyglycerol Esters of Fatty Acids (PGE), also known as Polyglycerol Fatty Acid Esters or Glycerin Fatty Acid Esters. These are functional ester-based materials produced by partially esterifying polymerized glycerol (polyglycerols) with edible fats, oils, or fatty acids. Their composition can vary according to the fatty-acid source and degree of glycerol polymerization, making them a versatile class of emulsifying and stabilizing materials.
Polyglycerol Esters of Fatty Acids are commonly identified as INS 475 / E475 and are recognized primarily for their emulsifying and stabilizing functions. Depending on their composition, they can range from relatively hydrophilic to lipophilic and may be supplied as oily liquids, viscous materials, soft solids, or hard waxy solids.
Polyglycerol Esters of Fatty Acids consist of a distribution of esterified polyglycerol molecules rather than one single defined chemical compound. The polyglycerol portion can contain different degrees of polymerization, while the fatty-acid portion can vary according to the selected source material. Therefore, a universal molecular formula or molecular weight cannot be assigned to the complete product class.
These characteristics allow PGE to function as an effective emulsifier, stabilizer, surface-active agent and formulation aid. Their lipophilic and hydrophilic balance can be adjusted through selection of the fatty-acid and polyglycerol components.
Depending on the specific grade and applicable regulatory requirements, Polyglycerol Esters of Fatty Acids can be considered for:
The product's final performance depends strongly on its fatty-acid composition, degree of esterification, polyglycerol distribution and HLB characteristics.
PGE is a mixed ester system that can contain mono-, di- and triglycerides, free glycerol and polyglycerols, free fatty acids and small quantities of fatty-acid salts depending on manufacturing and specification.
The material can therefore be customized or selected according to:
Swapnroop Pharma supplies Polyglycerol Esters of Fatty Acids for customers requiring consistent-quality formulation and industrial raw materials. Our product offering is intended for applications where controlled emulsification, stabilization, dispersion and surface activity are required.
Product documentation and specification parameters can be aligned with the specific grade, intended application and applicable customer requirements.
Polyglycerol Esters of Fatty Acids should be stored in tightly closed, suitable original packaging in a cool, dry and well-ventilated environment. Storage conditions should protect the material from excessive heat, moisture, contamination and prolonged exposure to unsuitable environmental conditions.
Packaging can be selected according to product form, grade, quantity and customer requirements.
