About

Propargite (iso) is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Propargite is an ISO-named acaricide (spider mite control agent) with restrictions in the EU. It is classified as a Category 2 suspected carcinogen under EU CLP Regulation (H351) and has been evaluated for cosmetic use. Propargite is not listed on EU Annex II (absolute ban), but its carcinogenic classification and specific provisions under EU REACH mean its use in cosmetic products is effectively prohibited. It is an omega-thiol ester insecticide with specific provisions requiring strict containment.

Known concerns

  • Suspected carcinogen (EU CLP Category 2, H351)
  • Not approved for cosmetic use in the EU
  • Environmental hazard — toxic to aquatic organisms
