Skin Benefits

It creates abundant foam that quickly lifts sweat, oils, and product buildup for a thorough rinse, though it may be drying for some users, making it better suited to occasional deep cleansing.

Uses In Skincare & Cosmetics

It appears in clarifying shampoos, foaming body washes, and liquid hand soaps for strong cleansing action, and is used in bubble baths and shower gels to deliver a high-foam experience.

Comedogenic Rating

This ingredient is not typically evaluated for comedogenicity, and no standardized rating is available.

Safety

It can be irritating and drying, particularly for sensitive or compromised skin, and may sting the eyes. Use it in well-rinsed products and avoid prolonged contact to limit barrier disruption. Trace 1,4-dioxane can be present from ethoxylation if not well purified, though reputable suppliers minimize it.

Is Sodium Laureth Sulfate a Good Ingredient?

It rates Fair because it delivers strong, quick cleansing and dense foam, but it also has a higher likelihood of dryness and irritation, especially for sensitive skin and color-treated hair, and may contain trace 1,4-dioxane if poorly purified. Milder co-surfactants and moisturizers typically temper this in finished formulas.
