About

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

An esterquat-type conditioning agent formed by esterification of hexyldecyl-myristoyl (C16-C18) alcohol with methylaminopropionic acid and subsequent quaternization. The esterquat structure (quat with an ester bond) offers both the conditioning performance of traditional quaternary ammonium compounds and enhanced biodegradability (the ester bond hydrolyzes in the environment). Used as a skin and hair conditioning agent in natural and organic-formatted cosmetics. No specific EU Annex II or III restriction; biodegradable esterquats are generally preferred over non-biodegradable counterparts from an environmental standpoint.

Skin benefits

  • Excellent skin and hair softening
  • Good emollient properties
  • Biodegradable alternative to non-ester quats
  • Leaves soft, silky after-feel

Known concerns

  • Generally safe and mild; theoretical hydrolysis products (fatty acids, methylaminopropionic acid) are mild
