Moderate

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

A cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

This compound is climbazole, a broad-spectrum imidazole antifungal used as a cosmetic preservative. It appears in EU CosIng with concentration limits: 0.5% in rinse-off products, 0.2% in other product types. H302 (harmful if swallowed), H400 (very toxic to aquatic life), H410 (toxic to aquatic life with long-lasting effects), H412 (harmful to aquatic life with long-lasting effects) reflect environmental concerns rather than direct human toxicity at approved concentrations. At regulated levels, it is considered safe for rinse-off cosmetic use, though environmental persistence is a concern.
