Disodium EDTA is a water-soluble chelating agent widely used in cosmetic and personal-care formulations to bind trace metal ions and support formulation stability. It is the disodium salt of ethylenediaminetetraacetic acid and is commonly supplied as a white crystalline powder.
Disodium EDTA has the CAS Number 139-33-3 for the anhydrous compound and the commonly supplied dihydrate form has CAS Number 6381-92-6. The anhydrous form has the molecular formula C₁₀H₁₄N₂Na₂O₈ and molecular weight 336.21 g/mol. The dihydrate form has the molecular formula C₁₀H₁₄N₂Na₂O₈·2H₂O and molecular weight 372.24 g/mol.
In cosmetic formulation development, Disodium EDTA is primarily used as a chelating agent. It can bind trace metal ions that may otherwise contribute to oxidation, discoloration, odor changes or degradation of sensitive formulation components.
Disodium EDTA is particularly relevant to aqueous and emulsion-based cosmetic systems. It can be incorporated into suitable shampoos, conditioners, facial cleansers, creams, lotions, liquid soaps, body washes and other personal-care formulations.
The exact concentration should be determined according to the formulation, regulatory requirements and the intended function of the ingredient.
Disodium EDTA is the disodium salt of ethylenediaminetetraacetic acid. It belongs to the class of aminopolycarboxylic acid chelating agents.
The anhydrous compound has CAS Number 139-33-3, while the dihydrate form has CAS Number 6381-92-6.
Disodium EDTA is commonly used in cosmetic formulations because of its ability to complex with trace metal ions. This property can help improve the stability and appearance of formulations containing ingredients that are sensitive to metal-catalyzed oxidation.
Important technical information includes:
Disodium EDTA is primarily used as a chelating agent in cosmetic and personal-care formulations.
It can help bind trace metal ions such as calcium, magnesium and certain transition-metal ions. This function can support the stability of formulations containing water, botanical ingredients, fragrances, colors and oxidation-sensitive components.
Potential applications include:
Disodium EDTA can be incorporated into suitable shampoo and hair-care systems as a chelating ingredient.
Potential applications include:
Its compatibility with surfactants, conditioning agents, preservatives, polymers and fragrances should be evaluated during formulation development.
Disodium EDTA can also be used in suitable cream and lotion formulations.
Potential applications include:
It can support formulation stability by binding trace metal ions that may otherwise contribute to undesirable changes during storage.
Disodium EDTA can be evaluated in aqueous cleansing formulations such as:
Formulators should evaluate its effect on pH, clarity, viscosity, preservative performance and overall formulation stability.
Important formulation considerations include:
The anhydrous and dihydrate forms should not be treated as identical for weight-based formulation calculations because their molecular weights differ.
