About

An anionic surfactant derived from laureth-9 (ethoxylated lauryl alcohol) neutralised with ammonium, used as a cleansing and foaming agent in personal care formulations.

Ammonium Laureth-9 Sulfate (CAS 32612-48-9) is the ammonium salt of ethoxylated lauryl ether sulfate with an average of 9 moles of ethylene oxide. The ethoxylation of lauryl alcohol reduces the irritation potential compared to the non-ethoxylated ammonium lauryl sulfate. The substance is not specifically listed in EU Annex II or III restrictions, though laureth sulfates in general have been subject to irritation assessments. At typical rinse-off concentrations (below 10-15%), it is considered safe.
