Swapnroop Pharma manufactures and supplies Polyglyceryl Stearate, a fatty-acid ester of polyglycerol used as a functional emulsifier, surfactant, stabilizer and formulation aid. It is produced by esterification of polyglycerol with stearic acid and is available in different grades depending on the degree of polyglycerol polymerization and esterification.
Polyglyceryl Stearate combines the hydrophilic characteristics of polyglycerol with the lipophilic properties of stearic acid. This provides useful interfacial and emulsifying properties for pharmaceutical, nutraceutical, cosmetic and specialty formulation applications.
Polyglyceryl Stearate is not a single molecular substance in all commercial forms. Its composition can vary according to the polyglycerol chain distribution, degree of esterification and fatty-acid composition. Therefore, the molecular formula and molecular weight are grade-dependent.
Different grades can provide different HLB characteristics, emulsification performance, viscosity and physical form. This makes Polyglyceryl Stearate suitable for formulation systems requiring controlled oil-water interaction and stabilization.
Depending on the specific grade and applicable regulatory requirements, Polyglyceryl Stearate can be used for:
Polyglyceryl Stearate provides several formulation functions, including:
The performance depends on the particular polyglyceryl grade, esterification level and fatty-acid profile.
Swapnroop Pharma supplies Polyglyceryl Stearate for customers requiring specialty formulation materials with consistent composition and application-specific characteristics.
We support bulk requirements and can provide product documentation corresponding to the supplied grade, including applicable CoA and SDS.
Polyglyceryl Stearate should be stored in tightly closed suitable packaging in a cool, dry and clean environment. The product should be protected from excessive heat, moisture, contamination and prolonged exposure to unsuitable environmental conditions.
Packaging can be selected according to product grade, quantity and customer requirements.
