Answer: Sodium Laureth Sulfate is not currently banned worldwide, but health agencies have flagged concerns. The FDA still allows it in US cosmetics and personal-care products. Risk level: low. Commonly found in: Pantene Pro-V Classic Clean Shampoo, Dove Deep Moisture Body Wash, Neutrogena T/Gel Therapeutic Shampoo.
TL;DR: Sodium Laureth Sulfate is allowed in the EU but allowed in the US (surfactant).

Sodium laureth sulfate (SLES) is an anionic surfactant derived from ethoxylated lauryl alcohol, widely used as a primary lathering and cleansing agent. It is milder than its close relative SLS because the ethoxylation process reduces skin irritation potential. SLES is one of the most common cosmetic surfactants globally.
SLES produces rich, stable foam and effectively removes oils, dirt, and residue from hair and skin, making it the backbone of shampoos, body washes, and facial cleansers.
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.

Regulatory status is not the same as a proven health effect — read the cited sources for their exact wording, and consult a doctor for decisions about your or your family's health.
Gentler alternatives include sodium cocoyl isethionate, disodium laureth sulfosuccinate, or coco-glucoside, all of which produce good foam with lower irritation potential for sensitive skin.
Yes. At typical shampoo and body wash concentrations (4–15%), SLES is safe for daily use. People with very sensitive or eczema-prone skin may prefer sulfate-free formulas, but this is a preference rather than a safety requirement.
No. SLES is not classified as a carcinogen by any major regulatory body. The 1,4-dioxane contamination concern is addressed by manufacturers through vacuum-stripping; final product levels are well below limits set by the FDA and EU.
No. SLES is fully permitted in EU cosmetics under Regulation (EC) 1223/2009 with no concentration restriction in rinse-off products.
