Science
Mechanism of Action
This modified starch functions primarily by absorbing finely dispersed substances, including excess sebum, thereby reducing shine on the skin. Its amphiphilic structure, comprising both hydrophilic and hydrophobic groups, makes it an effective emulsion stabilizer, preventing ingredient separation and maintaining product integrity. Furthermore, it acts as a viscosity controlling agent, allowing for precise adjustment of a cosmetic product's thickness while contributing to a superior texture and enhanced glide upon application.

Stability
Sodium Starch Octenylsuccinate demonstrates robust stability in both acidic and alkaline solutions. Its thickening capacity is reliably maintained up to pH 4.5. For specific applications, an alkaline environment, such as pH 8, has been shown to provide significantly enhanced long-term stability (up to one year). The ingredient can be dissolved in hot water, or in cold water following pregelatinization treatment, and forms stable emulsions resistant to both heat and shear conditions during processing.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed Sodium Starch Octenylsuccinate's safety for cosmetic use. It is recognized as Generally Recognized As Safe (GRAS) by the FDA in the United States for food and cosmetics, and is approved for use in the European Union under EC No 231/2012 (food additive E1450). Toxicological studies consistently show it to be non-irritating and non-sensitizing to the skin.
