ISOSTEARETH-10.

Valuable CAS 52292-17-8 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

ISOSTEARETH-10 is a versatile polyethylene glycol ether, primarily utilized as a surfactant and emulsifier in cosmetic formulations. Its unique molecular structure facilitates the creation of stable oil-in-water emulsions, essential for numerous skincare products. This ingredient is fundamental for product integrity and performance, ensuring immiscible liquids blend seamlessly.

Summary

emulsifying surfactant

Science

Mechanism of Action

This ingredient functions by significantly lowering the interfacial tension between oil and water phases, allowing them to form a homogeneous and stable emulsion. Its amphiphilic nature, possessing both lipophilic (oil-attracting) and hydrophilic (water-attracting) components, enables it to effectively disperse and stabilize oil droplets within a water base, or vice versa. Additionally, its surfactant properties contribute to cleansing by helping to solubilize oils and dirt for removal.

Safe with restrictions
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed alkyl PEG ethers, such as Isosteareth-10, safe for use in cosmetics when formulated to be non-irritating. Although a related compound, Steareth-10, demonstrated potential irritation at concentrations exceeding 60%, Isosteareth-10 is typically incorporated into products at significantly lower, non-irritating levels. It is also listed in the FDA Global Substance Registration System (GSRS).
