STARCH ACETATE.

Valuable / HAIR CONDITIONING, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

Starch Acetate is a modified starch derivative primarily employed in skincare for its superior ability to manage excess oil and sebum. It effectively promotes a matte finish, reduces skin shine, and refines the appearance of pores, while simultaneously acting as a skin conditioning agent.

Science

Mechanism of Action

Starch Acetate functions by efficiently absorbing excess oil and sebum present on the skin's surface, which leads to a significant reduction in unwanted shine and a minimized appearance of pores. Beyond its oil-controlling properties, it imparts a smooth, matte texture to the skin and serves as a conditioning agent, reducing the greasiness and stickiness often associated with cosmetic products.

The Cosmetic Ingredient Review (CIR) Expert Panel affirmed Starch Acetate as safe for cosmetic applications in their September 2015 review. While specific maximum concentrations for cosmetics are not detailed, a related ingredient, Distarch Phosphate Acetate, was also found safe. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) assigned an 'acceptable daily intake not specified' for food applications, indicating very low toxicity. Concerns regarding carcinogenicity, allergies & immunotoxicity, developmental and reproductive toxicity are all rated as 'LOW' by the Environmental Working Group (EWG).
