Environmental Applications
CAS No.: 60-00-4
Molecular Formula: C₁₀H₁₆N₂O₈
Molecular Weight: 292.24 g/mol
Product Overview:
Ethylenediaminetetraacetic Acid (EDTA) is a widely used chelating
agent known for its ability to bind with metal ions, making it
invaluable in various industrial, agricultural, and chemical
applications. It is available in both industrial grade and daily chemical grade, with high purity levels that make it suitable for a range of
formulations, from cleaning agents to water treatment chemicals,
pharmaceuticals, and more. EDTA efficiently forms complexes with
metal ions, preventing their adverse effects on products and
systems.
This product is available as a white crystalline powder, and its
high chelation value ensures strong and stable metal ion binding.
EDTA is known for its versatility in various sectors, including
agriculture, textiles, food processing, cosmetics, and industrial
manufacturing.

Applications:
Industrial Grade:
- Water Treatment: EDTA is used in water treatment to chelate metal
ions that may interfere with chemical processes, such as scaling in
boilers and cooling towers.
- Detergents & Cleaners: Used in formulations to improve the
efficiency of cleaning by binding with calcium, magnesium, and
other metals that can reduce soap and detergent effectiveness.
- Agriculture: EDTA is used to supply micronutrients to plants by
forming complexes with metal ions, enhancing nutrient availability.
- Textiles: Helps in dyeing processes by controlling metal ion
interference.
- Pharmaceuticals & Cosmetics: EDTA acts as a stabilizer in various
pharmaceutical and cosmetic formulations, ensuring consistent
performance and extending product shelf life.
Daily Chemical Grade:
- Personal Care Products: EDTA is included in shampoos, lotions, and
other personal care items to prevent the negative effects of metal
ions, improving product stability and effectiveness.
- Food Processing: Used as a stabilizer and preservative in food
products to bind trace metals and prevent oxidation, extending
shelf life.
Storage and Handling:
- Storage: Store EDTA in a cool, dry, well-ventilated area, away from
moisture and direct sunlight. Ensure containers are tightly sealed
to protect the product from contamination.
- Handling: Use appropriate personal protective equipment (PPE), such
as gloves and goggles, to avoid skin and eye contact. Ensure good
ventilation during handling to prevent inhalation of dust.
Caution:
- Safety: EDTA is generally considered safe when used according to
recommended guidelines. However, prolonged exposure or inhalation
of high concentrations should be avoided. In case of skin or eye
contact, rinse immediately with plenty of water.
- Regulatory Compliance: EDTA is compliant with relevant safety and
regulatory standards, but users should always consult local
regulations regarding its use in specific applications.
