Aluminum starch octenylsuccinate

* A complex carbohydrate made by plants.

Functions:

Acts as an anti-caking agent, a viscosity (resistance to flow) increasing agent, and an absorbent. Used in products like lotion, powder, and makeup, mainly for aesthetic purposes. For example, it can keep foundation from caking onto the skin, or lessen the greasy shine associated with certain lotions. It's also been shown to enhance the SPF factor in several sunscreens. In fact, as little as 5% aluminum starch octenylsuccinate can increase the SPF of titanium dixiode by 40%.

Safety Measures/Side Effects:

The Cosmetic Ingredient Review (CIR) Expert Panel has assessed this ingredient as safe to use in cosmetic products, provided that the already established limitations on certain heavy metal concentrations are not exceeded. Though aluminum is considered neurotoxic, studies have revealed no evidence of toxicity in aluminum starch octenylsuccinate.
