About
Strontium Chloride Hexahydrate is a cosmetic ingredient. Exercise caution due to limited available safety data.
Strontium chloride hexahydrate is used primarily in oral care products for the treatment of dentin hypersensitivity. EU cosmetic regulation specifies strontium limits: maximum 3.5% (as strontium) for certain uses and 2.1% (as strontium) for others, with combined strontium products not to exceed these limits. Strontium is related to calcium in the periodic table and can incorporate into hydroxyapatite in teeth. The restrictions reflect concerns about systemic strontium exposure over time.
