Aluminum Starch Octenylsuccinate

An absorbent that takes in oils from the skin to reduce the oily sheen. It can also absorb oils from the skincare product itself, resulting in a softer, less greasy product, normally with better spreadability and less tack.

What is Aluminum Starch Octenylsuccinate?

Aluminum Starch Octenylsuccinate is a white, fluffy, odorless powder that is derived from cornstarch that has been modified to be hydrophobic, or oil-loving. By chemically combining aluminum salt and starch derived from corn, scientists enhance its natural attributes, creating a substance that's perfect for a wide array of skincare applications.

Aluminum Starch Octenylsuccinate in Skincare

Aluminum Starch Octenylsuccinate performs many functions in skincare. Its primary benefits include:

  1. Absorbent: The compound's ability to absorb sebum makes it an excellent choice for products targeting oily skin. By reducing skin shine, it promotes a matte, fresh complexion. It can also absorb oils from the skincare product itself, leading to a softer, less greasy product, normally with better spreadability and less tack. 

  2. Anticaking: Aluminum starch octenylsuccinate also serves as an anticaking agent in dry powder products, like compact face powders. It prevents the clumping of ingredients, improving the application process and overall user experience. 

  3. Viscosity controlling: The compound effectively maintains the consistency of skincare products, by thickening oil-based formulations. This factor is essential for the stability and efficacy of various products, from creams to serums.

Is Aluminum Starch Octenylsuccinate Safe for Skin

The safety of Aluminum Starch Octenylsuccinate, a common ingredient in skincare and cosmetics, is well-supported by scientific findings. Esteemed organizations such as the Cosmetic Ingredient Review (CIR) Expert Panel and the European Commission on Health and Consumer Safety have endorsed its safety for cosmetic use.

These entities permit Aluminum Starch Octenylsuccinate in skincare products at concentrations up to 30%. At these levels, it is non-toxic, non-irritating, and non-allergenic. This makes it suitable for all skin types, even those prone to sensitivity.
