EDTA CAS NO： 60-00-4 Cosmetic Raw Materials

EDTA (Ethylenediaminetetraacetic Acid) - Premium Chelating Agent for Multi-Industry Use​

Product Description​

EDTA, a high-performance amino polycarboxylic acid chelating agent, appears as colorless to white crystalline powder with a slight water-solubility (0.5 g/100 mL at 25℃) . Its core strength lies in forming stable, water-soluble complexes with most di- and trivalent metal ions (e.g., Ca²⁺, Fe²⁺/Fe³⁺, Mg²⁺) even at neutral pH . With excellent thermal and chemical stability (stable across a wide pH range and temperatures up to 150℃), it effectively inhibits undesirable reactions caused by free metal ions, protecting product quality and process efficiency. As a versatile raw material, it serves as the foundation for various EDTA salts (e.g., EDTA 2Na, EDTA 4Na) while being widely used in pure acid form .​

Wide-Ranging Applications​

EDTA is an indispensable additive across diverse industries, trusted for its superior chelating performance :​

Water Treatment: Sequesters scale-forming metal ions (Ca²⁺, Mg²⁺) to prevent boiler/pipeline scaling; removes heavy metals in wastewater purification and industrial circulating water systems.​

Detergent & Cleaning Industry: Softens hard water, enhances cleaning power, and prevents soap scum formation in industrial cleaners, detergent formulations, and metal surface treatment agents.​

Textile & Paper Industry: Eliminates metal ion interference in dyeing processes for brighter, more uniform fabric colors; improves bleaching efficiency in pulp/paper production by protecting bleaching agents (e.g., hydrogen peroxide) from decomposition .​

Food Industry: Acts as a preservative and antioxidant synergist to inhibit oxidation and discoloration caused by metal ions, extending shelf life of canned foods, dressings, and processed products .​

Pharmaceutical & Cosmetic Industry: Stabilizes pharmaceutical formulations and cosmetic products (shampoos, lotions) by chelating metal ions, preventing active ingredient degradation and product discoloration .​

Other Fields: Used in oil drilling (stabilizes drilling fluids), agriculture (enhances micronutrient bioavailability), chemical analysis (metal ion masking agent), and synthetic rubber production .​
