Tetra Sodium of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid HEDP·Na4 Granule
Synonyms: Tetrasodium etidronate
CAS No.: 3794-83-0 EINECS No.: 223-267-7
Molecular Formula: C2H4O7P2Na4 Molecular weight: 294
Structural Formula:
Properties and Usage:
HEDP•Na4 is even granule with excellent fluidity, low dust content, low hygroscopicity and easy handling properties.
HEDP•Na4 is a powerful chelating agent. As a household cleaning agent and industrial cleaner auxiliary, HEDP·Na4 can stabilize metal ions in water and enhance effect of decontamination under high pH washing condition.
HEDP•Na4 can be used in cosmetics and personal care to restrain rancidity and discoloration.
HEDP•Na4 can be used as slow-release scale corrosion inhibitor after being compressed into tablets with other auxiliaries. HEDP•Na4 works as oxygen bleaching stabilizer in dyeing and paper making industry.
