EDTA (Ethylenediaminetetraacetic Acid) is a versatile aminopolycarboxylic acid, a staple across cosmetics, pharmaceuticals, water treatment and food processing for its exceptional chelating power. As a white crystalline powder (free acid, formula C10H16N2O8), its common derivatives (disodium/tetrasodium EDTA) feature an ethylenediamine core with carboxymethyl groups, forming stable complexes with metal ions. It tightly binds divalent/trivalent metals to prevent oxidation, performs stably across wide pH/temperature ranges, and dissolves easily in water, making it ideal for aqueous formulations and industrial processes.
China Adjusts Export Tax Rebate Policy: Rebates to Be Cancelled for Certain Products In accordance with the latest policy announcement issued by China’s Ministry of Finance and the State Taxation Administration, the value-added tax (VAT) export rebate for a range of industrial products will be fully cancelled, effective April 1, 2026. This adjustment is part of the national strategy to optimize industrial structure, promote high-quality development, and foster healthy competition in global markets.
Relying on amino acid technology, cell culture medium raw materials are mainly divided into two categories: cell culture media for biopharmaceuticals and stem cell/pluripotent stem cell culture media. Focusing on animal-free, chemically defined, high-density culture and high expression, they are the mainstream raw material system in the fields of biopharmaceuticals and cell therapy.
