Is Sodium Laureth Sulfate banned?

Sodium Laureth Sulfate is permitted by the US FDA. Several countries restrict, warning-label, or have reviewed it for safety concerns. The US has more lenient additive rules than the EU, UK, Canada, and Japan, which is why this ingredient remains widely used here.

Why Sodium Laureth Sulfate is flagged

SLES is broadly considered safe at cosmetic use levels (typically 1–20%). The Cosmetic Ingredient Review (CIR) Expert Panel concluded it is safe as used in rinse-off products. A known manufacturing byproduct, 1,4-dioxane, can appear at trace levels; reputable manufacturers use vacuum-stripping to minimize it below regulatory limits. SLES does not penetrate intact skin significantly and is not a carcinogen or systemic toxin. Some individuals with very sensitive or eczema-prone skin may experience mild irritation at higher concentrations; this resolves upon rinsing. It is not a hormone disruptor and does not accumulate in the body.
