General Description:
Disodium EDTA (Ethylenediaminetetraacetic Acid Disodium Salt) is a widely used chelating agent in the cosmetic, skincare, and personal care industries. It works by binding metal ions, preventing product degradation and improving the stability of formulations. Disodium EDTA enhances the effectiveness of preservatives and maintains product clarity. Available for bulk purchase, wholesale supply, and private label manufacturing, it is an essential ingredient for cosmetic manufacturers.
Uses in the Cosmetics Industry
Disodium EDTA is a key component in many beauty and personal care products, including:
β Shampoos & Conditioners β Improves foam quality and prevents mineral buildup.
β Skincare Products β Stabilizes formulations and enhances preservative efficiency.
β Soaps & Body Washes β Prevents discoloration and maintains product performance.
β Makeup & Foundations β Increases product longevity and prevents oxidation.
β Sunscreens & Lotions β Enhances texture and prevents ingredient separation.
Side Effects & Hazards
While Disodium EDTA is considered safe in regulated concentrations, some concerns include:
β Mild Skin Irritation β In rare cases, sensitive skin may experience mild irritation.
β Environmental Impact β Not easily biodegradable, raising concerns about water pollution.
β Formulation Sensitivity β Works best at specific pH levels to maximize effectiveness.
CAS Number: 139-33-3
INCI: Disodium EDTA
Composition: Disodium EDTA is derived from ethylenediamine, formaldehyde, and sodium cyanide. It is a white, crystalline powder composed of two sodium(Na) ions, one EDTA molecule, and water molecules coordinated around the central metal ion.
Purity Grade: No purity grade applicable
Appearance: Disodium EDTA typically appears as a white, crystalline powder.
Solubility: Disodium EDTA is highly soluble in water. It forms clear, colorless solutions when dissolved in water.
Preservation: Disodium EDTA itself does not possess preservative properties. However, its chelating properties help improve the effectiveness of preservatives by chelating metal ions, which can promote microbial growth and product degradation.
Storage: Store in a closed container at a dry place at room temperature
Raw Material Source: The raw materials for Disodium EDTA synthesis include ethylenediamine, formaldehyde, and sodium cyanide. Ethylenediamine is derived from ammonia and ethylene dichloride, while formaldehyde and sodium cyanide are produced from
various chemical processes.
Manufacture: Disodium EDTA is typically manufactured through a multi-step chemical synthesis process involving the reaction of ethylenediamine, formaldehyde, and sodium cyanide under controlled conditions. The reaction yields a complex intermediate, which is then hydrolyzed and neutralized to produce Disodium EDTA.
Animal Testing: Not animal tested
GMO: GMO-free (does not contain plant-derived components)
Vegan: Does not contain animal-derived components
Proposition: DISODIUM EDTA complies with relevant regulations and guidelines.
Warning: Avoid contact with eyes and skin. Use appropriate protective equipment when handling.
THE STORY OF DISODIUM EDTA
Disodium EDTA: The Essential Chelating Agent for Product Stability
Disodium EDTA is a highly effective chelating agent used across skincare, haircare, and personal-care formulations. It binds to metal ions that can cause instability, discoloration, rancidity, and loss of efficacy. Widely recognized as a key support ingredient, it helps maintain clarity, color, fragrance, and shelf stability in cosmetic products.
Synthetic Chelator Engineered to Neutralize Metal Impurities
Disodium EDTA is the disodium salt of Ethylenediaminetetraacetic Acid, created through controlled chemical synthesis.
It works by binding (chelating) metal ions such as:
β’ Calcium
β’ Magnesium
β’ Copper
β’ Iron
β’ Heavy metal traces
These ions often enter formulations through water, pigments, botanical extracts, or packaging. By binding them, EDTA ensures stability, clarity, and long-lasting product performance.
Stabilize. Protect. Preserve.
Key benefits in cosmetic and personal care products:
β
Prevents product discoloration and oxidation
β
Enhances preservative performance by reducing metal interference
β
Improves foam stability in shampoos and cleansers
β
Keeps fragrances stable and long-lasting
β
Prevents rancidity in oil-containing formulas
Used in: shampoos, face creams, toners, serums, gels, soaps, color cosmetics, and oral-care formulations.
Reliable, Safe & Globally Approved for Everyday Formulations
β’ Typical use level: 0.05β0.2% in most formulations
β’ Water-soluble; add to water phase during heating or mixing
β’ Compatible with surfactants, emulsifiers, preservatives & colorants
β’ Safe for skin and hair when used within cosmetic limits
β’ Widely approved in EU, US, ASEAN, India, Japan
β’ Store in cool, dry conditions to prevent clumping
β’ Available in Disodium EDTA (pH ~4β6) or Tetrasodium EDTA (higher pH systems)
