About this ingredient
Oxidized starch acetate (INCI: Oxidized Starch Acetate) is a plant-derived thickener, a starch modified by oxidation and acetylation for better stability and feel. It gives a soft powdery texture, absorbs excess oil and adds body to the formula. It is a functional component, not a treatment active. Its role is sensory and structural: it mattifies, improves slip and structures products like powders, masks or bases. It does not act on skin processes, so it is not a care ingredient in the strict sense. It is inert and has no systemic uptake topically, so it can be used during pregnancy and breastfeeding. Tolerance is high: low irritation potential and low allergy risk, fine for sensitive skin. Thanks to its oil-absorbing ability it usually suits even oily skin, with no notable comedogenic load.
