Disodium EDTA Description

Disodium EDTA is a salt of ethylenediaminetetraacetic acid (commonly known as EDTA). In cosmetics, it functions primarily as a chelating agent, meaning it prevents ingredients in a formula from binding with trace elements (mainly minerals) that can be present in water or other ingredients. This action enhances the stability of cosmetics formulas and helps makes the job of preservatives easier since EDTA ingredients bond with mineral ions that microorganisms need to remain intact. In addition to being used in makeup, skin care, and hair care products, disodium EDTA is also used as a food additive.

In several studies, the Cosmetics Review Board has found that as used in cosmetics products, disodium EDTA is safe. It was determined that in the concentrations used in commercial cosmetics, it is not a skin sensitizer nor a carcinogen, and does not penetrate through skin. The highest concentration of disodium EDTA used in leave-on products is 0.85% (for hair color sprays).

Disodium EDTA

​EDTA Na2 (ethylenediaminetetracetic acid disodium) is a chelating agent, used to sequester and decrease the reactivity of metal ions that may be present in many industrial and personal care products.

Industrial Applications

EDTA Na2 is used in cleaners, detergent, fertilizers, fixer solution for development of colour film, water cleaner and pH modifier. It is also used in redox reaction for the polymerization of butyl benzene rubber, it is used as part of activator for the control of polymerization speed.

Personal Care Applications

EDTA Na2 is used in Cosmetics to increase effectiveness and improve stability of bar and solid soaps, bath preparations; creams, oils, hair care products and many other personal care formulations.

disodium ethylenediamine tetraacetic acid

Ethylenediaminetetraacetic acid is a molecule which complexes metal ions in aqueous environments. It is available in four neutralizations, two of which, Disodium EDTA and Tetrasodium EDTA, are commonly used in cosmetics. Generally, the choice of which product to use is determined by the intended pH of your product. Disodium EDTA is commonly used in neutral to mildly acidic products, like most creams, lotions, and neutral pH liquid soaps and shampoos.

EDTA catalyzes metal ions, which can be present in any water-based system. 

These metal ions can react with formulation ingredients causing problems, including: 

Spoilage and rancidity

Degradation of vitamins and essential fatty acids

Fragrance degradation,

Discoloration

Haze formation and precipitation

Poor foaming and rinsability performance.

EDTA also works synergistically with your preservative to improve preservative efficacy.

Disodium EDTA may also be called EDTA, or ethylenediaminetetraacetic acid, and it is used in many personal care and consumer products. It is found as a main ingredient in many commercially prepared foods, cosmetics, household cleaners and also in skin care and hair care products.

Disodium EDTA has properties that preserve and stabilize solutions. It is purifies products especially when tap water or another type of questionable water source is used. Disodium EDTA is also used as a chelating agent which effectively removes metal ions in the water. It can also control the viscosity in solutions making skin care products easy to use and apply on to the skin.
