WHAT IS IT? Aluminum Starch Octenylsuccinate is the aluminum salt of the reaction product of Octenylsuccinic Anhydride with starch. Used in foundations, skin moisturizers, lipsticks, eye shadows, concealers, sunscreens and facial powders as an anti-caking and viscosity increasing agent, Aluminum Starch Octenylsuccinate is no scarce ingredient, found in concentrations as high as 30% in many of these products.

HEALTH RISK: Its main health concerns include:

– Developmental/reproductive toxicity (reproduction and fertility)
– Birth or developmental effects
– Contamination concerns – arsenic, lead, heavy metals
– Neurotoxicity, organ system toxicity (non-reproductive)

We think that is reason enough to avoid using this chemical!

A Healthier Alternative: Try Tom’s Natural Confidence Roll-On Deodorant – it contains all natural ingredients and potassium alum derived from ore from the earth.

  2. Could you send me details of research and findings of tests done on aluminum-starch-octenylsuccinate as I am working on some research which shows that this product is used in a potentially deadly sun tan lotion.

  3. can we have some background on the molecule and how likely it is that the aluminium will detach and leach from said molecule?
    My instinct is to avoid it, but I’d like to know for sure.

  4. I purchased an anti aging product, and this was one of the first 3 ingredients in the product. The first I used it, I had a pimple within 1 hour. I’m returning. Thanks for the information.

  5. Another site says otherwise, with direct references to studies: https://www.ewg.org/skindeep/ingredients/700326-ALUMINUM_STARCH_OCTENYLSUCCINATE

    It is not enough to proclaim a product toxic (or avoid a product) without at least linking to your claims. Google is your friend.
