Is Oleth-10 a Good Ingredient?
Rated Good because this nonionic PEG surfactant reliably solubilizes oils and stabilizes cleansers, with typically low irritation when properly formulated: solid, dependable performance, but nothing that pushes it into a higher tier.

Generally well tolerated, though higher concentrations or use near the eyes can cause mild stinging or dryness. PEG-based surfactants are not known to be comedogenic; sensitive users may wish to patch test.
