Chemical compound
Zinc lactate is a chemical compound, a salt of zinc and lactic acid with the formula Zn(C3H5O3)2.[1][2]
Synthesis
Reaction of lactic acid with zinc oxide:
- 2CH3CH(OH)COOH + ZnO → Zn(C3H5O3)2 + H2O
Physical properties
Zinc lactate appears as a white to almost white fine powder.
Zinc lactate is nearly odourless, highly soluble in water,[3] and insoluble in ethanol.
Zinc lactate forms dihydrates with the chemical formula Zn(C3H5O3)2 • 2H2O.
Use
The compound is used in dental care products like toothpaste or mouthwash.[4]
Can also be used as a dietary ingredient and as a nutrient.[5]
The compound has antioxidant properties in mammals and can improve intestinal function.[6]
