Ammonium laureth sulfate

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

Where is Ammonium laureth sulfate used?

• Shampoos and body washes: primary surfactant
• Rinse-off formats: foam volume and cleansing action
• Sensitive-skin and mild-formula lines: ethoxylated structure is milder than non-ethoxylated alternatives
• Liquid hand soaps and facial cleansers: compatibility with secondary surfactants and conditioning agents
• Light-duty household cleaning liquids: degreasing and emulsification of oily soils
• It removes soil and sebum while producing a dense, stable lather.

Good to know: Buyers should confirm ethoxylation degree and active content when evaluating lots; these parameters affect formulation performance and cost-in-use.

Commercial specifications

• Typically 25–30% active matter concentration
• Standard commercial grades for personal care and cosmetic applications
• Store in a cool, dry place
