About

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

Linuron is an ISO-named urea herbicide prohibited from use in cosmetic products under EU Cosmetics Regulation (EC) No 1223/2009. It is classified as a Category 2 suspected carcinogen under EU CLP Regulation and is listed on the EU REACH Authorisation List (Annex XIV). Linuron acts as a photosynthesis inhibitor in plants and has been associated with bladder and thyroid tumors in animal studies. Its environmental persistence and toxicity to aquatic organisms further reinforce its prohibition in consumer products.
