Zinc acetate dihydrate
Description
Zinc acetate dihydrate (CAS 5970-45-6) is an inorganic zinc salt supplied as a crystalline solid with established use across pharmaceutical, food, and industrial manufacturing sectors.
It delivers zinc as a bioavailable source for nutritional supplementation and functions as a catalyst precursor, pH buffer, and preservative across multiple formulation types and chemical processes.
In pharmaceuticals, it is used as an active ingredient in zinc deficiency treatments and as an excipient in topical formulations where controlled zinc release is required for therapeutic efficacy.
Food and feed manufacturers use it as a zinc fortification agent in nutritional products, dietary supplements, and animal feed premixes to ensure proper mineral intake and health maintenance.
In polymer and plastics processing, it acts as a catalyst precursor for polymerization reactions and as a stabilizer component to improve the durability and performance of synthetic materials.
Personal care formulators incorporate it into oral care products and astringent preparations where its buffering and mild preservative properties support product stability and user safety.
Zinc acetate dihydrate is available as a white crystalline powder or granules. Recognized grades include USP, BP, Ph. Eur., FCC, and technical grade for diverse sourcing needs.
These standards support sourcing across regulated pharmaceutical, food, and industrial applications. Purity specifications typically range from 98% to 101% on a dry basis depending on the grade.
