INCI: Sodium Gluconate
CAS No. 527-07-1 / 14906-97-9
EC No. 208-407-7 / 238-976-7
Sodium gluconate is the sodium salt of gluconic acid produced by the fermentation of glucose. It is very soluble in water white crystalline powder. Noncorrosive, nontoxic and readily biodegradable (98% after 2 days). Sodium gluconate chelating agent is exceptional, especially in concentrated alkaline solutions.
Exceeds other chelating agents such as EDTA, NTA and related compounds.
Aqueous solutions of sodium gluconate are resistant to oxidation and reduction, even at high temperatures.
Sequestering agents are chemical compounds having the property of being able to associate with metal ions to form stable complexes, also called chelating agents. Some sources say that the name comes from the Greek word chele or khele which means claw or clamp.
Chelation happens when the sequestering agent binds to the metal forming a chelate compound coordinated or avoiding the precipitation of metals in aqueous solutions and avoiding oxidative reactions.
Les chelating agents have the function of capturing metal ions, forming complexes that have the property to remain soluble and safe, which is of great importance in some industrial processes, avoiding undesirable in the production process or in the final product effects.
As sequestering agents polyphosphates, aminocarboxylic acids and some carboxílicos.Uno acid sequestrants commonly used for various applications are used is EDTA (ethylenediaminetetraacetic acid) and its derivatives. Other chelating agents are citric acid, ascorbic acid, tartaric acid among others.
Examples of applications are:
-Water Water: As water softener, sequestering trap metal ions such as Ca +
-Industry Soaps and detergents: Sequestering help form water-soluble complexes and improve their properties.
-Production Of cosmetics: Sequestering prevent rancidity, retain the components and help stabilize the color.
Soap is prone to rancidity caused by traces of heavy metals that promote the oxidation of the unsaturated components.
The use of chelating agents such as sodium gluconate help extend the life of the soap.
Use 0.3% of the total weight of soap and it will dissolve well in water we use to prepare the caustic solution.
It can be combined with sodium citrate to increase the chelating effect on soap.
We will use up to 3% of the weight of sodium citrate oils.
