PEG-30 dipolyhydroxystearate

PEG-30 dipolyhydroxystearate (CAS 827596-80-5) is a polymeric PEG ester derived from polyhydroxystearic acid, functioning as a high-performance emulsifier and rheology modifier for water-in-oil systems.

It stabilizes emulsions where conventional surfactants fail, particularly in high-electrolyte or high-pigment load formulations. In color cosmetics, it enables stable water-in-oil foundations and BB creams.

It is frequently used in sunscreens with high mineral pigment content, preventing phase separation under thermal stress. Suncare formulators rely on it to suspend and disperse UV filters evenly.

Both organic and inorganic filters are dispersed throughout emulsion matrices. In pharmaceutical topicals, it supports the manufacture of stable w/o creams and ointments where controlled rheology is critical.

Emulsion integrity is essential to dosage consistency in medical applications. Personal care manufacturers also use it in long-wear and transfer-resistant formulations where a firm texture is required.

A structured emulsion texture is achieved through its unique chemical properties. PEG-30 dipolyhydroxystearate is typically supplied as a waxy solid or flake for industrial handling.

It is available in cosmetic-grade and pharmaceutical-grade specifications to meet the purity requirements of regulated end markets. Packaging is commonly offered in kilogram quantities for development.

Procurement options range from small scale through to drum quantities for commercial production. This material ensures high stability across a wide range of temperature and storage conditions.
