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.

  6. The link described above as well as so many other “google” sites, are primarily based on the: Food and Drug Administration (FDA), Canadian Environmental Protection Act (CEPA). The National Library of Medicine (NLM). EAFUS [Everything Added to Food]: A Food Additive Database. FDA Office of Food Safety and Applied Nutrition.
    All these “Scientific Data” it’s from Government Agencies that are directed by the Pharmaceutical companies themselves. Who consequently “sponsor and do the funding” for all the “Safety” Scientific Evidence and Data collected to demonstrate it’s “safety” and get approval to place ON ALL FOOD and SKIN,SCALP,FACE PRODUCTS.

    This “Safe” product is ADDED on ALL Commercial flour(Basically ALL Breads have it), Cake flours, baking powders, lots of condiments, baby formulas, Coffe Creamers… Deodorants, Body lotions, Shampoos, Conditioners ..
    So by the end of the day .. your (1) Ingredient Goverment “Safety Product” .. becomes 20 TIMES the Quantity INSIDE your body.
    1- Ingested=GI organs every time you eat.
    2- Through your SKIN (lotions) (sun-blocks)
    3- Through your lymphatic nodes (Deodorant)
    4- Through your scalp/forehead (shampoos/conditioners).
    It’s the CUMULATIVE EFFECT … Simple Math!!
    * Research ONLY Non-Gov/3rd party non-bias sources.

  7. Thanks Bella Bel. That’s a good point about Google. Just decided to compare a tube of working hands hand cream vs same brand but in the green plastic container. I noticed the tube had different ingredients including this crap. I love that hand cream but I guess I will stick to the plastic twist top vs the squeeze tube.
