About
Cupric Sulfide is a cosmetic ingredient. Exercise caution due to limited available safety data.
Cupric Sulfide (CuS) is an inorganic copper sulfide mineral with no EU CosIng entry and no established safety assessment for cosmetic use. While copper is an essential trace element, the sulfide form and particulate nature raise concerns for skin accumulation and potential ecotoxicity. The absence of GHS hazard statements in available data suggests lower acute toxicity than copper oxide, but data are insufficient for a confident safety assessment.
Known concerns
- No established cosmetic safety data
- Limited toxicological profile
- Copper sulfide particulate accumulation concern
