Our take
Is PEG-10 Isostearate a Good Ingredient?
Rated Good as a mild, effective nonionic emulsifier and solubilizer that supports cleansing and makeup removal without the harshness of stronger surfactants. Some users may experience eye stinging or slight irritation at higher use levels, which keeps it from a higher tier.
