Polyoxyethylene sorbitan triisostearate

Polyoxyethylene sorbitan triisostearate (CAS 54392-28-8), also known commercially as Emery 14233, is a nonionic ethoxylated sorbitan ester derived from isostearic acid. It functions primarily as an emulsifier and wetting agent across personal care, industrial, and textile applications.

This versatile chemical is utilized where stable oil-in-water or water-in-oil systems are required. In cosmetic formulations, it stabilizes emulsions in creams, lotions, and color cosmetics, particularly where isostearic acid's branched structure improves skin feel.

The compound effectively reduces greasiness in topical applications while maintaining formulation integrity. Textile and leather processors use it as a wetting and softening agent during fiber treatment, dyeing, and finishing operations.

In industrial and household cleaning formulations, it aids dispersion of oils and soils by improving substrate wetting on hard-to-penetrate surfaces. This makes it an essential component for high-performance cleaning solutions.

Food-contact and specialty industrial applications may also utilize it as an emulsifying component where ethoxylated sorbitan esters are technically accepted. It provides reliable performance across a wide range of pH levels and temperatures.

Polyoxyethylene sorbitan triisostearate is typically supplied as a viscous liquid or paste at ambient temperature. It is available in technical and cosmetic grades, with cosmetic-grade material commonly evaluated against standard industry purity benchmarks.

Packaging is generally offered in drums or intermediate bulk containers suited to industrial procurement volumes. Our supply chain ensures consistent quality and availability for large-scale manufacturing requirements and specialized laboratory needs.
