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.
