Aluminium Starch Octenylsuccinate is a powdered synthetic substance used as a thickening agent, absorbent and anti-caking agent in skincare and cosmetics.
Aluminum Starch Octenylsuccinate is the aluminum salt of the reaction product of octenylsuccinic anhydride with starch. It is used in cosmetics at concentrations as high as 30% as an anticaking agent and a nonaqueous viscosity increasing agent. When used in foods, it is identified as a modified food starch, and is subject to limitations on heavy metal residues[1].
The Expert Panel for Cosmetic Ingredient Safety reviewed newly available studies since their original assessment in 2002, along with updated information regarding product types and concentrations of use, and confirmed that Aluminum Starch Octenylsuccinate is safe as a cosmetic ingredient in the practices of use and concentration as described in this report[2].
