Specifications:

Characteristics:

• Appearance: Tetrasodium Ethylenediaminetetraacetic acid is typically a white crystalline powder, and the specific appearance can vary slightly depending on the grade.

• Chelation Value: Tetrasodium EDTA is a strong chelating agent, and its ability to form stable complexes with metal ions is crucial in various applications such as water treatment, agriculture, and cosmetics.

• Purity: The purity of this compound ranges from 99.0% to 99.5%, with the industrial-grade material typically offering the lowest purity level, and the daily chemical grade having higher purity requirements.

• Chemical Composition: It contains sodium (Na) and ethylenediaminetetraacetic acid (EDTA), and in the form of dihydrate, it includes water molecules that aid in its solubility and stability.

Uses and Applications:

Tetrasodium EDTA is widely used across various industries due to its chelating properties:

• Water Treatment: It helps in softening water by binding to metal ions like calcium and magnesium, preventing scaling and corrosion.
• Cosmetics and Personal Care: Used as a stabilizer and preservative by sequestering metal ions that could cause product degradation.
• Detergents: It improves the effectiveness of surfactants by binding to metal ions in the water.
• Agriculture: In fertilizers, EDTA is used to make micronutrients more available to plants by binding to trace metals.
• Industrial Cleaning: It can enhance the cleaning process by removing metal ions from surfaces or solutions.
