FUNCTIONAL USES Sequestrant, antioxidant synergist, preservative 

EDTA is the commonly used abbreviation for (Ethylene­dinitrilo)­tetra­acetic Acid (also called Ethylene­diamine­tetra­acetic Acid or Edetic Acid). The Disodium salt of EDTA is the most commonly used form of this versatile organic complexing agent, which is used for the determination of many metal ions either by direct titration or by back-titration. Adjustment of reaction conditions, either by controlling the pH or by use of masking agents, and selection of the appropriate indicator permits a wide variety of metal ions to be determined using EDTA.

Molarity is best used in expressing EDTA concentration, because the reaction involves the complexation of one metal ion by one EDTA molecule or ion, whether the free acid form of EDTA or one of its more soluble Sodium salts is used. The general reaction involving the Disodium salt is:

EDTA2- + Mn+ → [EDTA-M]+n-2
where M = Ca, Mg, Cd, Mn, Ni, Al, Zn, Bi, Co, Cu, or other metal ion

An indicator is added that forms a colored complex with some of the metal ion being determined. When the endpoint is reached, all of the free metal ion has been complexed by the EDTA. The last addition of EDTA then removes the metal ion from its complex with the indicator, producing a color change. The relative strength of the EDTA-metal ion complex compared to that of the indicator-metal ion complex determines whether a direct titration or a back-titration is applicable.

EDTA is most commonly used to determine hardness (i.e., Calcium and Magnesium ions) in water, where the pH must be approximately 10 and is usually controlled by adding a buffer such as Water Hardness Buffer. Water Hardness Indicator (Eriochrome Black T), Eriochrome Blue Black R, Calmagite, and Murexide are used for hardness or Calcium determinations using EDTA.

Classification: EDTA


EDTA (EDTA and its main salts used in Disodium EDTA cosmetics, Tetrasodium EDTA, Trisodium EDTA) is a chelating agent that has been used since the 1930s and for which industrialists have complete control of processing and use. Its main property is to complex heavy metals. That is to say, it will somehow neutralize them by forming with them a complex, then serve them as carriers and evacuate them. It is therefore quite logically used in medicine to fight against heavy metal poisoning (lead for example).
It is often used as a sequestrant (calcium, limestone ...) in soaps or shower gels, this allows to manage the "hard" water.

Its functions (INCI)
Chelating : Reacts and forms complexes with metal ions that could affect the stability and / or appearance of cosmetic products
Viscosity controlling : Increases or decreases the viscosity of cosmetics

E Edetate Disodium (EDTA)
Edetate disodium (EDTA) is a chelating agent that is utilized for its metal-binding properties. 
It is best known as a treatment for calcific band keratopathy and has been used to neutralize corneal injuries due to calcium hydroxide, also known more commonly as lime burns. 
As a preservative, it has shown to inactivate trace amounts of heavy metals in very low concentrations.


Disodium EDTA is in many products as a preservative, to stabilise it, or to enhance the foaming action. 
It’s also used as a chelating agent, which means it us used to precipitate out metals from the formulation 


Disodium EDTA
Disodium EDTA and the related ingredients bind to metal ions which inactivates them. The binding of metal ions helps prevent the deterioration of cosmetics and personal care products. 
Disodium EDTA also helps to maintain clarity, protect fragrance compounds, and prevent rancidity.

Cosmetics
In shampoos, cleaners, and other personal care products, Disodium EDTA is used as a sequestering agent to improve their stability in air.


A chelating agent that sequesters a variety of polyvalent cations such as CALCIUM. It is used in pharmaceutical manufacturing and as a food additive.


EDTA (ethylenediamine tetraacetic acid) and its salts, Calcium Disodium EDTA, Diammonium EDTA, Dipotassium EDTA, Disodium EDTA, TEA-EDTA, Tetrasodium EDTA, Tripotassium EDTA and Trisodium EDTA, and the related ingredients HEDTA (hydroxyethyl ethylenediamine triacetic acid) and its trisodium salt, Trisodium HEDTA, are crystalline powders often sold as aqueous solutions.

In cosmetics and personal care products, these ingredients are widely used and can be found in moisturizers, skin care and cleansing products, personal cleanliness products, bath soaps, shampoos and conditioners, hair dyes, hair bleaches, and many other product types.

EDTA, also known as edetic acid, and its salts were developed to counteract the effects of hard water and heavy metal ions in the manufacture of textiles. 
These metal chelators are widely used in cosmetics and personal care products, in food, and in medicines.

Disodium EDTA forms complexes with calcium, magnesium, and iron, which allows for better foaming and cleaning performance of cosmetics and personal care products. 
By binding with metal ions, Disodium EDTA prevents the metals from being deposited onto the hair, scalp and skin.


Disodium EDTA is a chelating agent which removes excess build-up of minerals.

Disodium EDTA is sold as a water soluble white powder that is slightly acidic.
It also enhances foaming and appeals to consumers who like this added feature.


Ethylenediaminetetraacetic acid (EDTA) is an aminopolycarboxylic acid with the formula [CH2N(CH2CO2H)2]2. 
This white, water-soluble solid is widely used to bind to iron and calcium ions. It binds these ions as a hexadentate ("six-toothed") chelating agent. 
EDTA is produced as several salts, notably disodium EDTA, sodium calcium edetate, and tetrasodium EDTA

Disodium EDTA is mainly used to sequester metal ions in aqueous solution. 
In the textile industry, it prevents metal ion impurities from modifying colours of dyed products. 
In the pulp and paper industry, Disodium EDTA inhibits the ability of metal ions, especially Mn2+, from catalysing the disproportionation of hydrogen peroxide, which is used in chlorine-free bleaching. 
In a similar manner, Disodium EDTA is added to some food as a preservative or stabiliser to prevent catalytic oxidative decolouration, which is catalysed by metal ions.
In soft drinks containing ascorbic acid and sodium benzoate, EDTA mitigates formation of benzene.[6]

The reduction of water hardness in laundry applications and the dissolution of scale in boilers both rely on EDTA and related complexants to bind Ca2+, Mg2+, as well as other metal ions. 
Once bound to EDTA, these metal centres tend not to form precipitates or to interfere with the action of the soaps and detergents. For similar reasons, cleaning solutions often contain EDTA. 
In a similar manner Disodium EDTA is used in the cement industry for the determination of free lime and free magnesia in cement and clinkers.

The solubilisation of Fe3+ ions at or below near neutral pH can be accomplished using EDTA. 
This property is useful in agriculture including hydroponics. 
However, given the pH dependence of ligand formation, EDTA is not helpful for improving iron solubility in above neutral soils. 
Otherwise, at near-neutral pH and above, iron(III) forms insoluble salts, which are less bioavailable to susceptible plant species. 
Aqueous [Fe(EDTA)]− is used for removing ("scrubbing") hydrogen sulfide from gas streams. 
This conversion is achieved by oxidising the hydrogen sulfide to elemental sulfur, which is non-volatile:

2 [Fe(EDTA)]− + H2S → 2 [Fe(EDTA)]2− + S + 2 H+
In this application, the iron(III) centre is reduced to its iron(II) derivative, which can then be reoxidised by air. 
In similar manner, nitrogen oxides are removed from gas streams using [Fe(edta)]2−. The oxidising properties of [Fe(edta)]− are also exploited in photography, where it is used to solubilise silver particles.[4]

EDTA was used in separation of the lanthanide metals by ion-exchange chromatography. 
Perfected by F. H. Spedding et al. in 1954, the method relies on the steady increase in stability constant of the lanthanide EDTA complexes with atomic number. 
Using sulfonated polystyrene beads and Cu2+ as a retaining ion, EDTA causes the lanthanides to migrate down the column of resin while separating into bands of pure lanthanides. 
The lanthanides elute in order of decreasing atomic number. Due to the expense of this method, relative to countercurrent solvent extraction, ion exchange is now used only to obtain the highest purities of lanthanides (typically greater than 99.99%)

Preservative and sequestrant in foods Ethylenediaminetetraacetic acid, widely abbreviated as EDTA, is a polyamino carboxylic acid and a colourless, water-soluble solid. 
Its conjugate base is named ethylenediaminetetraacetate. It is widely used to dissolve limescale. 
Its usefulness arises because of its role as a hexadentate ("six-toothed") ligand and chelating agent, i.e. its ability to "sequester" metal ions such as Ca2+ and Fe3+. 

After being bound by EDTA, metal ions remain in solution but exhibit diminished reactivity. 
EDTA is produced as several salts, notably disodium EDTA and calcium disodium EDTA. (Wikipedia)

Ethylenediaminetetraacetic Acid, Disodium Salt, Dihydrate (Na2EDTA•2H2O), is a chelator of divalent metal cations. 

DISODIUM EDTA
Disodium EDTA is a chelating agent. It is used in viscosity controlling. 
Disodium EDTA deactivates the metal ions through bonding with them which inturn prevents cosmetic products from deteriorating.

A salt of an organic acid (Ethylenediaminetetraacetic Acid, disodium salt) used in aqueous solutions with other reagents and inert materials for the preparation of cleaning mixtures and poultices to be applied to stone surfaces and frescoes. 
EDTA disodium salt, for its property of complexing calcium within crusts and for its good solubility (better than tetrasodium salt), is used in the AB 57 poultice (I.C.R. formulation - Rome). 
It is besides a strong chelating agent of a great many metallic cations, as iron and copper; this property can be utilized to remove stains of rust or copper green from stone surfaces, wood, plasters, etc…
