About

A copper-citrate chelate used to stabilise photo-sensitive ingredients and provide trace copper for skin. Generally tolerated at low cosmetic levels, but free copper can irritate eyes, so use is kept conservative.

Function

  • Acts as a UV-induced oxidation inhibitor
  • Provides trace copper for some skin-conditioning effects

Known concerns

  • Free copper ions can cause eye irritation if released
