Polyethylene Glycol Stearate is a nonionic surfactant and polyethylene glycol ester of stearic acid. It is used as a functional pharmaceutical excipient, emulsifier, solubilizer, surfactant, wetting agent and formulation aid.
Polyethylene Glycol Stearate is available in different grades, commonly identified by the approximate molecular weight of the polyethylene glycol component, such as PEG 400 Stearate and PEG 600 Stearate. The properties of the material therefore depend on the selected grade and manufacturing process.
Swapnroop Pharma manufactures and supplies Polyethylene Glycol Stearate in India for qualified pharmaceutical, nutraceutical, cosmetic and specialty formulation applications.
Polyethylene Glycol Stearate provides both hydrophilic polyethylene glycol functionality and a lipophilic stearate component. This amphiphilic structure makes it useful in formulations requiring surface activity and emulsification.
Depending on the grade, it can function as:
Polyethylene Glycol Stearate may be used in selected pharmaceutical and topical systems to assist with emulsification, dispersion and incorporation of oil-soluble or poorly water-soluble ingredients.
Potential applications include:
The appropriate grade should be selected based on the required HLB, PEG molecular weight, acid value, saponification value, melting characteristics and formulation performance.
Polyethylene Glycol Stearate consists primarily of esterified polyethylene glycol and stearic acid components. A simplified structural representation for a PEG stearate ester is:
CH₃(CH₂)₁₆COO–(CH₂CH₂O)ₙ–H
Commercial products can contain mixtures of monoesters, diesters and related components depending on the manufacturing grade.
Consequently, the exact molecular formula and molecular weight are grade-dependent rather than representing one universal compound.
Swapnroop Pharma supplies Polyethylene Glycol Stearate to pharmaceutical manufacturers, formulation developers, nutraceutical companies and other qualified customers.
Grade selection can be aligned with requirements for:
Polyethylene Glycol Stearate should be stored in tightly closed, moisture-protective packaging in a cool, dry and clean environment. Excessive heat, moisture, direct sunlight and contamination should be avoided.
Storage conditions should follow the applicable product specification and SDS.
Depending on the selected grade and customer requirements, documentation may include:
