Description of key information

Relative density: ca. 1.7 to 2.0 at 20°C (read across from citric acid and metal-citrate salts)

Key value for chemical safety assessment

Additional information

Citric acid has a relative density of 1.7 at 20°C. Trisodium citrate, tripotassium citrate and tricalcium dicitrate have relative densities of 1.86, 1.96 and 1.83 at 20°C, respectively. Based on read-across within this category, trizinc dicitrate can be said to have a density in the range 1.7 to 2.0 at 20°C.
