Isopropanolamine lauryl sulfate

Isopropanolamine lauryl sulfate (CAS 21142-28-9) is an anionic surfactant produced by neutralizing lauryl sulfuric acid with isopropanolamine. It functions as a foaming, cleansing, and emulsifying agent in personal care and industrial cleaning formulations.

This chemical offers a milder neutralizing base compared to conventional sodium or ammonium counterparts. In shampoos, body washes, and liquid hand soaps, it delivers effective sebum and soil removal alongside stable, dense foam.

Formulators working on conditioning cleansers favor it where the isopropanolamine counter-ion contributes to improved compatibility with conditioning actives. It is highly effective in household and industrial cleaning products.

Including hard surface cleaners and degreasers, it provides strong wetting and emulsification of oils and greases. It also functions as a dispersing agent in liquid detergent concentrates for various applications.

The surfactant helps maintain formulation stability across a range of pH conditions. Isopropanolamine lauryl sulfate is typically supplied as a liquid or paste, with active matter content commonly ranging around 30–35%.

It is available in technical and cosmetic grades suited to personal care and industrial cleaning end uses. Buyers should confirm active content, pH specification, and color grade with suppliers based on requirements.
