About this ingredient

Dextrin is a low-molecular-weight polysaccharide obtained by partial hydrolysis of starch (corn, potato, tapioca). Known in the food industry as a thickener; in cosmetics – a neutral filler and stabilizer. Mechanism. Absorbs oil and excess sebum, takes up moisture, gives the formula bulk. Forms a thin film with a mattifying effect on skin. In dry formulas (powders, powder masks) it works as a filler and stabilizer. In liquids – as a thickener and emulsifier. Where applied. Mineral powders, loose foundations, dry shampoos, powder masks, cleansing gels, antiperspirants. In Spain – Mercadona Deliplus in mass-market powders, niche artisan soaps, Klorane hair products (dry shampoos). Evidence base. A functional component with many years of use. Absorbent properties confirmed in standard tests. No standalone active skin pharmacology. Safety. CIR confirmed dextrin safety in cosmetic use. Hypoallergenic, non-comedogenic, non-irritating. In patients with celiac disease a reaction is theoretically possible to wheat dextrin (contains traces of gluten); to corn and potato – no. Pregnancy and lactation – safe without restrictions. Best suited to: any skin type, especially oily and combination (thanks to absorbent properties). Almost a standard in color cosmetics.
