About

Cis-dichloroethylene is a cosmetic ingredient. Exercise caution due to limited available safety data.

cis-1,2-Dichloroethylene (CAS 156-59-2) is a halogenated alkene used primarily as an industrial solvent and refrigerant. It is classified as a volatile organic compound (VOC) with hazard concerns including acute toxicity by inhalation, skin absorption, and suspected carcinogenicity. Under EU Regulation 1223/2009, substances classified as carcinogenic, mutagenic, or toxic to reproduction (CMR) in categories 1A/1B are banned from cosmetic products (Annex II, entry 1222/2009 precursor). While not specifically listed by name, the hazard profile makes it incompatible with cosmetic use in the EU.
