Cobalt Benzenesulphonate is a cosmetic ingredient. Exercise caution due to limited available safety data.

Cobalt benzenesulphonate (CAS 23384-69-2) is an organocobalt compound that has been used in cosmetic and industrial formulations as a drier and catalyst. EU Regulation 1223/2009 Annex III restricts its use to concentrations below 0.1% as a constituent of substances or mixtures. Like other cobalt compounds, cobalt benzenesulphonate raises concerns due to cobalt's classification as a skin and respiratory sensitizer, and its IARC classification as a probable human carcinogen (Group 2A) when inhaled. The compound shares the toxicological concerns of other cobalt compounds including potential for cobalt allergy and systemic effects.

Known concerns

  • Restricted to <0.1% in EU mixtures
  • Cobalt skin and respiratory sensitization
  • Suspected carcinogen (Group 2A IARC)
  • Cobalt allergy and contact dermatitis
  • Potential for systemic cobalt effects
