Zinc bisglycinate

Zinc bisglycinate (CAS 14281-83-5), also known as zinc glycinate or Zinc Chelazome, is an amino acid-chelated zinc salt formed by coordinating zinc with two glycine molecules. It carries no assigned E-code and is classified under HS code 2922.49.8000.

In personal care formulations, it functions as a skin and hair conditioner by delivering bioavailable zinc to the tissue while simultaneously acting as a humectant to retain moisture. In pharmaceutical and nutraceutical applications, its chelated structure improves zinc absorption compared to inorganic salts. It also provides antimicrobial activity and pH buffering in topical and oral preparations.

Zinc bisglycinate is available in powder and crystalline grades suitable for cosmetic, food supplement, and feed applications. Procurement should verify compliance with REACH registration requirements and confirm grade specifications against FCC or Ph.Eur. standards depending on the intended application. Packaging formats vary by supplier and order volume.
