HYDROLYZED CORN STARCH OCTENYLSUCCINATE.

Valuable / ABSORBENT, BINDING, FILM FORMING

Hydrolyzed Corn Starch Octenylsuccinate is a versatile cosmetic ingredient recognized for its multi-functional role in skincare formulations. It primarily acts as an absorbent, effectively managing excess oil and moisture to deliver a smooth, matte skin finish. Beyond its immediate skin benefits, it enhances product aesthetics by improving texture and spreadability while also contributing to overall formulation stability.

Science

Mechanism of Action

On the skin, Hydrolyzed Corn Starch Octenylsuccinate functions by absorbing surface lipids and moisture, which helps to create a desirable matte appearance and smooth tactile feel. Its film-forming properties contribute to a temporary barrier, while its binding capabilities improve the cohesion of cosmetic products. Furthermore, this modified starch derivative can retain moisture, offering a degree of skin hydration, and plays a crucial role in maintaining the overall integrity and ease of application of cosmetic formulations.

Stability

This ingredient demonstrates stability within an optimal pH range of 4.0 to 7.0, aligning well with the skin's natural slightly acidic to neutral pH. To preserve its properties and product efficacy, formulations containing this ingredient should be stored protected from excessive heat and moisture. It also actively contributes to the enhanced stability of the cosmetic product itself.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Hydrolyzed Corn Starch Octenylsuccinate, alongside similar polysaccharide gums, safe for use in cosmetics under current practices and concentrations. While a specific maximum concentration for this ingredient was not established by CIR, a related compound, Aluminum Starch Octenylsuccinate, has been utilized in leave-on products at concentrations up to 30%. It is important to note that the Scientific Committee on Consumer Safety (SCCS) has reviewed Aluminum Starch Octenylsuccinate for different purposes but has not specifically assessed Hydrolyzed Corn Starch Octenylsuccinate. FDA status regarding cosmetic use is not explicitly detailed, though food-grade modified starches are regulated for heavy metal content.
