About

A toxic heavy metal and its compounds, prohibited from cosmetic use due to severe systemic toxicity. Trivalent and pentavalent antimony compounds are particularly hazardous.

Antimony and its compounds (including antimony trioxide, antimony pentoxide, and antimony sulfide) are metalloid compounds with significant toxicity. Antimony compounds are toxic to the skin, respiratory system, and gastrointestinal tract. Some antimony compounds are suspected carcinogens (IARC classification varies by compound; antimony trioxide is IARC Group 2A). EU regulations restrict antimony and its compounds in cosmetic products. The severe restrictions cited reflect the hazard even at low concentrations in mixtures.
