About

P-Cumenyl)-2-Methylpropionaldehyde is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

3-(p-Cumenyl)-2-methylpropionaldehyde (also known as cumulene or 2-methyl-3-(p-isopropylphenyl)propionaldehyde) is a branched aldehyde fragrance compound. It carries GHS hazard classifications H317 (may cause allergic skin reaction) and H361 (suspected of damaging fertility or the unborn child), earning it a Warning signal word. Under EU Regulation 1223/2009 Annex III, fragrance compounds with H361 reproductive toxicity flags face additional scrutiny, and the SCCS notes this class of aromatic aldehydes for potential sensitization at consumer exposure levels.

Skin benefits

Known concerns

  • Skin sensitization (H317)
