About

Hc Red No. 13 is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

HC Red No. 13 is listed in EU Annex III/237 of Cosmetics Regulation 1223/2009, indicating restricted use in hair dye formulations at specified concentrations. As with other HC dyes, it contains a nitro group and amine functionality that confer both colour and sensitisation risk. Patch-test studies have documented positive reactions in patients with contact allergy to oxidative hair dyes. Safe use requires compliance with the specific conditions of the Annex listing, including intended use restrictions and concentration limits.

Known concerns

  • EU Annex III/237 restricted — concentration limits apply
  • Documented contact allergy/dermatitis cases
  • Restricted to hair dye use only
