About this ingredient
PEG-20 Stearate (INCI same) is a non-ionic emulsifier. It binds water and oil and gives a stable creamy texture. It appears in creams, lotions and emulsions of all kinds. On efficacy: this is a functional emulsion ingredient, not a skincare active. It does not treat skin; its role is to keep the formula uniform so the real actives can spread evenly. As an emulsifier it reliably does its job. It is topical, with no meaningful systemic absorption. It can be used during pregnancy and breastfeeding. Tolerance is good: low irritation and allergy potential, suitable for sensitive skin. PEG emulsifiers at use concentrations are well tolerated on intact skin.
