About

Aluminum dimyristate — an aluminum-fatty-acid salt used to thicken and stabilise color cosmetics and waxy products. CIR-supported as safe at typical use levels; the only caveat is that it inherits the aluminum-cosmetics conversation.

Skin benefits

  • Acts as a viscosity controller and structurant in waxy systems
  • Stabilises emulsions, especially in color cosmetics
  • Improves pigment dispersion
  • Low odor, neutral feel

Known concerns

  • Aluminum content places it in the wider aluminum-cosmetics discussion
  • Insoluble — does not penetrate intact skin but inhalation concerns in loose powder
  • Limited solo dataset; relies on class read-across
