About

Violacein is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Violacein is a bis-indole purple pigment produced by several bacteria including Chromobacterium violaceum and Janthinobacterium lividum. It exhibits broad-spectrum antimicrobial, antioxidant, and anti-inflammatory activities. While the pigment itself is structurally unique, its safety in topical cosmetic formulations is not fully established. Natural pigments from biological sources may present allergenicity concerns, and large-scale purity assessment is required. It is not prominently listed in CosIng with an approved function.

Known concerns
