For these fragrance ingredients, Sweden suggested classification as category 1B Reprotoxic. This would mark the start of a process that would ultimately see these substances listed as CMRs, whose use, unless exempted, is prohibited in cosmetic products in Europe.

The notification of intention of classification concerned eight substances:
• Cuminaldehyde (CAS 122-03-2)
• p-Cymene (CAS 99-87-6)
• 3-p-Cumenyl Propionaldehyde (CAS 7775-00-0)
• Cyclamen Aldehyde (CAS 103-95-7)
• 4-tert-Butyldihydrocinnamaldehyde (CAS 18127-01-0)
• Methyl 4-t-Butylbenzoate (CAS 26537-19-9)
• 4-t-Butylbenzaldehyde (CAS 939-97-9)
• 4-tert-Butyltoluene (CAS 98-51-1)

ECHA has just announced that five of these have been withdrawn for :
• Cuminaldehyde
• 3-p-Cumenyl Propionaldehyde
• Methyl 4-t-Butylbenzoate
• 4-t-Butylbenzaldehyde
• 4-tert-Butyltoluene
