How we scored it
Where it comes from
Made from corn, potato or tapioca starch reacted with octenyl succinic anhydride (from petrochemical 1-octene and maleic anhydride) at a low substitution level, then partially neutralized with aluminum. The starch backbone supplies almost all the molecule's mass.
In plain English
A modified corn, potato or tapioca starch treated with a small amount of octenyl succinic acid and aluminum. Helps powders resist clumping and absorbs excess oil in formulas.
CosIng definition: Starch, hydrogen octenylbutanedionate, aluminum salt
