Ammonium laureth sulfate

Ammonium laureth sulfate (CAS 32612-48-9 ), commonly abbreviated as ALES, is an ethoxylated anionic surfactant used as a primary cleansing and foaming agent in personal care formulations.

It delivers effective soil and sebum removal while producing a dense, stable lather that consumers associate with product performance. In shampoos and body washes, ALES functions as the primary surfactant.

It generates the foam volume and cleansing action required in rinse-off formats. Its ethoxylated structure makes it milder than non-ethoxylated alternatives, positioning it for sensitive-skin and mild-formula product lines.

It is also incorporated into liquid hand soaps and facial cleansers where compatibility with secondary surfactants and conditioning agents is a formulation priority for the manufacturer.

In light-duty household cleaning liquids, ALES contributes both degreasing performance and emulsification of oily soils. This versatility makes it a staple ingredient in many industrial cleaning applications.

Ammonium laureth sulfate is supplied as a clear to slightly hazy aqueous solution, typically at 25–30% active matter concentration. Standard commercial grades are available for personal care and cosmetic applications.

Suppliers commonly offer material conforming to cosmetic-grade specifications. Buyers should confirm ethoxylation degree and active content when evaluating lots for their specific production needs.

These parameters directly affect formulation performance and cost-in-use. Proper storage in a cool, dry place is recommended to maintain the stability and efficacy of the surfactant over time.
