About this ingredient
Aluminum Starch Octenylsuccinate is a corn starch modified with octenyl succinic anhydride and stabilized with aluminum salts. INCI: Aluminum Starch Octenylsuccinate. A white powder with high absorbent capacity. In cosmetics it works as a mattifier and absorbent: it soaks up sebum and gives the formula a soft-focus effect, optically softening pores and fine irregularities. It is used in creams for oily and combination skin, foundations, loose and pressed powders, and deodorants. Use levels run from 1 to 15%. Pregnancy safety. The molecule is large and does not penetrate the skin. The aluminum content is bound in an insoluble complex – concerns about systemic absorption are not supported. CIR rates the safety profile as acceptable. Skin profile. Low irritation and allergen potential. Non-comedogenic at standard use levels. Suitable for oily, combination and normal skin. On very dry skin it may increase the feeling of tightness. There are no active cosmetic effects – purely a sensorial and functional component.
