About

Strontium Polycarboxylate is a cosmetic ingredient. Exercise caution due to limited available safety data.

Strontium polycarboxylates are strontium salts of polycarboxylic acids used in some industrial and dental applications. EU regulation restricts strontium compounds in cosmetic products due to concerns about strontium absorption through skin and potential deposition in bone (substituting for calcium). Annex III restrictions limit strontium compounds at ≥0.1% in cosmetic products. Strontium's chemical similarity to calcium raises concerns about bone-seeking behavior, particularly in long-term use.

Known concerns

  • Skin absorption of strontium
  • Bone-seeking behavior concern
  • Calcium substitution担忧
  • Restricted to ≤0.1% in EU cosmetics
