Frequently Asked Questions
What is zinc citrate trihydrate?
Zinc citrate trihydrate (CAS 5990-32-9) is the hydrated zinc salt of citric acid, supplied here in a purified grade with formula C12H14O16Zn3. It is used in oral-care formulations and as a zinc source for food fortification and supplements.
Is zinc citrate the same as zinc?
No. Zinc citrate is a zinc salt of citric acid, not elemental zinc metal. It delivers zinc in a citrate-bound form; the trihydrate carries water of crystallization, so its zinc content per gram is lower than anhydrous grades.
Is zinc citrate water soluble?
Zinc citrate has limited solubility in water and dissolves more readily under acidic conditions. Formulators should verify solubility behavior for the specific oral-care or fortification system being used.
What is the HS code for zinc citrate trihydrate?
It classifies under HS 2918.15 (salts and esters of citric acid). Confirm the final classification with your customs broker for your format and destination.
