DDBAC (Didecyldimethylammonium Chloride), a quaternary ammonium compound (QAC), is widely used as a disinfectant, surfactant, and biocide due to its strong antimicrobial activity and surface-active properties. 1. Key Properties of DDBAC (1) Chemical Structure Chemical Name: Didecyldimethylammonium Chloride CAS No.: 7173-51-5 Molecular Formula: C₂₂H₄₈ClN Appearance: Colorless to pale yellow viscous liquid Solubility: Soluble in water (forms a clear…
Corrosion inhibitor: EDTMPS forms complexes with metal ions, inhibiting metal corrosion and oxidation, thereby acting as a corrosion inhibitor. It effectively protects metal equipment, pipes, and systems from corrosion and damage. Scale remover: EDTMPS has excellent dissolution and removal capabilities for carbonate and sulfate scale in hard water containing calcium and magnesium. It can effectively…
EDTMPS is the same as EDTMPS; they are actually the same substance, namely sodium ethylene diamine tetra (methylene phosphonic acid) pentasodium salt. Therefore, there is no difference between EDTMPS and EDTMPS; they are simply different names for the same water treatment agent. This substance is a highly effective corrosion inhibitor and scale inhibitor, suitable for…
