The regulation added new harmonised classifications for 27 substances to Annex VI of CLP.

Several substances have been classified as CMR, which are used in cosmetics:

  • Silver (nano): [particle diameter > 1 nm ≤ 100 nm] H361f Repr 2, H373 STOT RE2 (nervous system)’
  • Silver Powder: [particle diameter > 100 nm < 1 mm] H361f Repr 2, H373 STOT RE2 (nervous system)’
  • Silver Massive: [particle diameter ≥ 1 mm] H361f Repr 2, H373 STOT RE2 (nervous system)’
  • Hexyl Salicylate (perfume ingredient) H361d Repr. 2
  • Copper [specific surface area > 0,67 mm2/mg] [CAS 7440-50-8] which covers the deleted entry for granulated copper [CAS 7440-50-8] (H400 Aquatic Acute 1, H410 Aquatic Chronic 1 )
    • Currently copper is listed as approved colourant (IV/132)
    • Copper (Nano) has been already banned aby cosmetic regulation and included in Annex II
  • α-methyl-1,3-benzodioxole-5-propionaldehyde [CAS 1205-17-0] (INCI: METHYLENEDIOXYPHENYL METHYLPROPANAL ) H317, Skin Sens. 1B
  • 2,4-dimethylcyclohex-3-ene-1-carbaldehyde [CAS 68039-49-6] INCI: 2,4-DIMETHYL-3-CYCLOHEXENE CARBOXALDEHYDE) H317, Skin Sens

Other substances classified as CMR cat. 1 that are permitted for use by professionals only:

  • acetone oxime [CAS 127-06-0], H350 Carc 1B
  • sodium 3-(allyloxy)- 2-hydroxypropanesulphonate [CAS 52556-42-0], H360F Repr.1B
  • benthiavalicarb-isopropyl (ISO) [CAS 177406 -68-7] H350 Carc.1B, H361 fd Repr.2

The regulation amended harmonised classifications for 16 existing substances in Annex VI of the CLP.

This includes but is not limited to:

  • N-hexane [CAS 110-54-3],
  • formaldehyde [CAS 110-54-3],
  • formic acid [CAS 64-18-6] – more stringent classification applied due to physical properties or human health effects
  • trimethyl borate [CAS 121-43-7] – tightened classification as CMR cat. 1
  • peracetic acid [CAS 79-21-0],
  • dibenzoyl peroxide [CAS 94-36-0],
  • dicamba (ISO) [CAS 1918-00-9] – expanded classification to include acute and/or chronic environmental toxicity
