Sodium starch octenylsuccinate is a modified starch derived from corn or other plant sources, used in skincare and cosmetics as an oil-absorbing, mattifying, and texture-enhancing ingredient. It helps create a soft, dry, powdery feel and can stabilize emulsions.

Skin irritation | Rare | Mild irritation possible in sensitive individuals, though it is generally considered well tolerated. |
Allergic contact dermatitis | Very rare | Isolated reports; starch derivatives rarely sensitize. |
Pore congestion / comedogenicity | Rare | May contribute to clogged pores in acne-prone skin when used in heavy formulations. |
