About 9-Vinylcarbazole

A vinyl polymerizable monomer with skin sensitization and environmental toxicity concerns that is prohibited above trace levels in EU cosmetics.

Detailed Analysis

9-Vinylcarbazole (N-vinylcarbazole) is a vinyl monomer used in polymer and photoconductor manufacturing. EU CLP classification includes H302/H300 (acute toxicity), H312 (harmful in contact with skin), H315/H317 (irritation/sensitization), H318 (serious eye damage), H341 (mutagenicity suspected), and H400/H410 (aquatic toxicity). The EU Cosmetics Regulation Annex III restricts 9-vinylcarbazole at ≥0.1% in cosmetic products. Its vinyl group allows polymerization but raises concerns about residual monomer and skin sensitization.
