Trilon B (EDTA Disodium Salt)
Formula:
C₁₀H₁₄N₂Na₂O₈
GOST/CAS:
CAS 6381-92-6 / ГОСТ 10652-73
Trilon B (Ethylenediaminetetraacetic acid disodium salt dihydrate) is a highly effective analytical reagent and chelating (complexing) agent. The primary function of the product is to extract metal ions from insoluble metal salts and replace them with sodium ions. Due to its unique ability to bind ions of calcium, magnesium, iron, and other heavy metals, Trilon B is an indispensable component in the production of pharmaceuticals, cosmetics, household chemicals, as well as in thermal power engineering and water treatment.
Applications
Pharmaceuticals & Cosmetics: Used as a stabilizer and preservative in solutions, ointments, and drops. It prevents the oxidation of active ingredients by binding trace heavy metals, significantly extending the shelf life and stability of preparations.
Water Treatment & Thermal Power: Applied for cleaning heat exchange equipment, boilers, and pipelines from scale, limescale, and rust. It effectively softens water by binding hardness salts.
Household Chemicals & Detergents: Included in the formulation of liquid soaps, shampoos, laundry detergents, and cleaning agents to enhance their foaming and washing capacity in hard water.
Laboratory Research & Analytical Chemistry: Widely used in titrimetric analysis (complexometry) for the precise determination of metal ion concentrations in solutions.
Key Advantages
High Chelating Capacity: Forms extremely stable, water-soluble complex compounds (chelates) with a wide range of metal ions across a broad pH range.
Stability and Purity: The substance is manufactured in strict compliance with high-quality standards, guaranteeing minimal content of foreign impurities and a stable granulometric composition.
Synergistic Effect: In household chemical and cosmetic formulations, it enhances the action of antioxidants and preservatives, allowing for a reduction in their required dosage.
Safety in Handling: The product is stable during storage, non-volatile, and non-flammable. It acts as a biodegradable component under controlled disposal conditions.
Storage & Transportation
- Store in dry, cool, and well-ventilated warehouses in tightly closed original packaging, away from strong oxidizing agents and alkalis.
- Recommended temperature range: no strict limitations; however, due to the product's hygroscopicity, rapid temperature fluctuations should be avoided to prevent caking.
- Protect from direct sunlight and moisture exposure.
- Transportation is permitted by all types of covered transport in compliance with standard cargo regulations. The material is classified as non-hazardous for transport. Shelf life is 3 years.
