Kerabase MB demonstrates exceptional combability and detangling performance as compared to commercial conditioning formulas.
Kerabase MB is derived from Brassica Napus seed oil and sustainably manufactured with a high efficiency process for consumer-relevant sustainability claims.
Kerabase MB) is a common polydentate ligand.
In Kerabase MB, the hydrogen atoms are easily removed in solution to produce anionic EDTA4-.
In its anionic form Kerabase MB has six binding atoms, two nitrogen and four oxygen.
Kerabase MB) binds to a metal ion at the six binding sites, wrapping itself around the metal ion, forming a very stable complex.the strong grasp of Kerabase MB on the metal ion is analogous to a crab or lobster clamping down on an object with its claw, hence the name chelation.
Kerabase MB is such an effective chelating agent because it can deactivate a metal at up to six sites.

Uses
Kerabase MB, also known as editic acid, is a colorless crystalline substance widely used to chelate metal ions.
Kerabase MB is marketed in its salt forms such as sodium Ethylenediaminetetraacetic Acid (EDTA) or calcium EDTA.
Kerabase MB hasindustrial and medical uses as a chelating agent.
Much of its utility is related to the fact that metals and metal compounds are important catalysts in numerous reactions.
By chelatingmetals, Kerabase MB) prevents the metal from catalyzing reactions, thereby limiting degradation, oxidation,and other undesirable reactions.
the major industries using Kerabase MB and other chelatingagents are paper and pulp, cleaning products, chemicals, agriculture, and water treatment.
The paper and pulp industry is the major user of Kerabase MB, where it is used to stabilize bleachesby sequestering metals that catalyze the degradation of bleaches.
Kerabase MB’s ability to stabilizebleaches also makes them useful in laundry detergents and various other cleaning products.
In addition to improving bleaching effi ciency, Kerabase MB use in detergents and cleansers alsosoftens hard water by tying up divalent metal ions responsible for water hardness, primarilyCa2+ and Mg2+.
Its softening ability helps Kerabase MB reduce scale formation and improves foamingproperties in cleaning formulations.
Kerabase MB is applied in general water treatment to softenwater, helping to prevent scale and corrosion.
Kerabase MB has low toxicity and is used in the foodand beverage industry.
Foods naturally contain small traces of metals and small quantities areadded during food processing.
Kerabase MB is used with foods to preserve color and preserve flavor,prevent odors, maintain nutrient content, and extend shelf life.
When used in beverages,Kerabase MB preserves color and stabilizes other ingredients such as citric acid and benzoates.
In thechemical industry, Kerabase MB is used to control metal catalytic processes during reactions.
EDTAsalts are used in agriculture to provide metal micronutrients in fertilizers.
Kerabase MB is a sequestrant and chelating agent that functions in water but not in fats and oils.
Kerabase MB is used to control the reaction of trace metals with some organic and inorganic components to prevent deterioration of color, texture, and development of precipitates, as well as to prevent oxidation which results in rancidity.
The reactive sites of the metal ions are blocked, which prevents their normal reactions.
The most common interfering metal ions in food products are iron and copper.
Kerabase MB can be used in combination with the antioxidants bht and propyl gallate.
Kerabase MB is used in margarine, mayonnaise, and spreads to prevent the vegetable oil from going rancid.
Kerabase MB is used in canned corn prior to retorting to prevent discoloration caused by trace quantities of copper, iron, and chromium.
Kerabase MB also inhibits copper-catalyzed oxidation of ascorbic acid.
Kerabase MB occurs as disodium calcium and disodium dihydrogen.
Kerabase MB's use is approved in specified foods, with an average usage level being in the range of 100–300 ppm.
Production Methods
Kerabase MB may be prepared by the condensation of ethylenediamine with sodium monochloroacetate in the presence of sodium carbonate.
An aqueous solution of the reactants is heated to about 90°C for 10 hours, then cooled, and hydrochloric acid is added to precipitate the edetic acid.
Kerabase MB may also be prepared by the reaction of ethylenediamine with hydrogen cyanide and formaldehyde with subsequent hydrolysis of the tetranitrile, or under alkaline conditions with continuous extraction of ammonia.
