Skin Benefits
Helps lift daily buildup and makeup so skin feels clean and refreshed. Contributes to a light, residue-free finish after rinsing.
Uses In Skincare & Cosmetics
Common in gel cleansers, micellar waters, and makeup-removing lotions to aid dispersion of oily impurities. Also appears in shampoos to improve cleansing performance in mild systems.
Comedogenic Rating
This ingredient is not typically evaluated for comedogenicity, and no standardized rating is available.
Safety
May cause irritation or stinging, especially on sensitive or compromised skin and around the eyes; use at low levels and rinse thoroughly. Modern manufacturing controls aim to minimize residual ethylene oxide and 1,4-dioxane, but cautious users may still prefer alternatives. No widely recognized special regulatory restrictions apply at rinse-off levels.
Is Oleth-3 a Good Ingredient?
Rated Fair: it's an effective low-level solubilizer and cleanser, but it's more irritating than milder surfactants and can disrupt the skin barrier if overused, which is why it doesn't rate higher.
