About

Methyl Acetyl Ricinoleate is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

Methyl acetyl ricinoleate is the methyl ester of acetylated ricinoleic acid, derived from castor oil (Ricinus communis). It functions as a skin-conditioning agent and emollient in cosmetic formulations. The acetylation of ricinoleic acid (which contains a hydroxyl group at C12) modifies its polarity and skin-feel properties. No hazard statements are listed, and the compound has a favorable safety profile typical of esterified vegetable oil derivatives.

Skin benefits

  • Skin-conditioning emollient
  • Improves product spreadability and texture
  • Derived from natural castor oil with long safety history

Known concerns

  • Generally considered safe with no hazard classifications
