Zinc Lactate

Introduction

Zinc lactate dihydrate is produced by complete neutralisation of lactic acid with a high purity zinc source and subsequent crystallisation.

Due to its antimicrobial properties and its ability to reduce or inhibit the formation of dental plaque and tartar, zinc lactate is mainly used in dental care products like toothpaste or mouthwash. As an organic mineral, it is preferred over inorganic sources because of its superior bioavailability, physiological compatibility and nearly neutral taste compared to other zinc salts.

Zinc lactate is supplied as a white to almost white fine powder. It is nearly odourless and highly soluble.
