Description
Zinc oxide (CAS 1314-13-2) is an inorganic compound sold under trade names including Ozlo, Ozide, Azodox, Amalox, and Actox 14. It carries no assigned E-code and is identified under EC 215-222-5. It functions primarily as an antimicrobial agent, skin protectant, and colorant across multiple industrial sectors.
In personal care formulations, zinc oxide provides broad-spectrum UV attenuation and antimicrobial action by releasing zinc ions that disrupt microbial cell membranes. In rubber and elastomer compounding, it acts as an activator for sulfur vulcanization, accelerating crosslink formation and improving mechanical properties. Coatings manufacturers use it as a corrosion-inhibiting pigment with documented antifungal performance.
Zinc oxide is available in standard and nanopowder grades, with the nanopowder form subject to additional REACH nanomaterial notification requirements in the EU. Relevant quality standards include Ph.Eur. and USP monographs for pharmaceutical and cosmetic applications. It is classified under HS code 28170000 and supplied in multi-layer paper sacks or bulk containers.
