About this ingredient
Propylene glycol stearate (INCI: Propylene Glycol Stearate) is a waxy ester that works both as an emollient and a co-emulsifier. In a formula it softens skin, gives a cream body and helps hold the water and oil phases together. This is a functional component, not a skincare active. Its value lies in the texture and stability of the product, not in an effect on skin. It makes a cream uniform and pleasant on application, and that is exactly its purpose. In topical use it has no systemic relevance, so it can be used during pregnancy and breastfeeding without any foreseeable risk. Tolerance is good, with low irritation and allergy potential. Its comedogenicity is moderate (around 2), so oily or acne-prone skin should watch the response and pick lighter formulas when it sits high on the ingredient list.
