Caution

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

Lidocaine HCL is a cosmetic ingredient. Raw material has significant toxicity. Exercise caution due to limited available safety data.

Lidocaine hydrochloride is a local anesthetic of the amide type used for its numbing effect. EU Cosmetic Regulation restricts lidocaine to a maximum concentration of 0.01% in ready-to-use rinse-off products (Annex III, reference II/399). Topical lidocaine presents systemic toxicity concerns, particularly in vulnerable populations. The ingredient carries acute toxicity warnings (H301, H302). These restrictions limit cosmetic applications primarily to post-procedure treatments under medical supervision.
