What is Ammonium Laureth Sulfate?
Ammonium laureth sulfate is an anionic surfactant very similar in structure to SLES but uses an ammonium counterion instead of sodium. It produces abundant foam and provides excellent conditioning to the hair shaft during washing.
Why is Ammonium Laureth Sulfate used in personal-care products?
ALES is favored in shampoos and some body washes for its slightly lower viscosity compared to SLES, which can make formulation easier. It also leaves hair with a softer feel post-rinse.
What regulators have flagged about Ammonium Laureth Sulfate
Ammonium laureth sulfate shares a similar safety profile to SLES. The CIR has concluded it is safe for cosmetic use. Like SLES, it may contain trace 1,4-dioxane from ethoxylation, addressed by standard manufacturing controls. It is not a carcinogen or endocrine disruptor. Mild skin irritation is possible in sensitive individuals at high concentrations but is not a concern at typical use levels in rinse-off products.
