About
A rare earth inorganic compound of cerium used in cosmetics primarily as an abrasive or opacifying agent, with limited safety data available.
Cerium Phosphate is an inorganic salt of the lanthanide series element cerium. While cerium compounds are used in industrial applications (catalysts, phosphors for displays), their use in cosmetics is limited and not well-documented in EU safety assessments. Cerium is considered less toxic than many other heavy metals, but the phosphate form has not undergone extensive toxicological evaluation for dermal exposure. No specific EU restriction or safety assessment for cosmetic use was identified.
