Sodium Gluconate Applications

I. Industrial Products

Concrete & Terrazzo Flooring
Sodium gluconate is widely used in the concrete industry in several applications. One of the reasons gluconate finds favor over other materials is its uniform quality and consistent performance.

The advantages of gluconate include:
Reducing water without sacrificing workability and strength.
Retarding setting time and improving workability without Increasing water addition. This will aid in difficult conditions, such as, long hauling times, hot summer days or tropical weather operations and placement of concrete in large areas.
Improving resistance of freeze-thawing.
Decreased bleeding, segregation, drying shrinkage and cracking.
As a water reducer, sodium gluconate allows better workability of the concrete mix and provides increased slump. By careful modification of the water-cement ratio and the addition of sodium gluconate, adjustments can be made to increase strength of the structure or actually reduce the cement content while maintaining the original strength. Besides its wetting agent function, sodium gluconate is a good retarder.

Gluconates along with certain materials have also been found to inhibit corrosion with used in reinforced concrete structures.

Plastics
Gluconate anion is often added in the form of sodium gluconate in condensation polymer manufacturing processes to form water soluble complexes with a fraction of the multivalent transition metal cations. Complexation beneficially hinders transition metal salts from precipitating in the manufacturing equipment and from contaminating the polymer product.

Paints
The addition of gluconate to highly alkaline paint strippers will increase their ability to remove enamels, lacquers, alkyds and modified epoxies. Gluconates improve the paint strippers penetration and softening characteristics, thereby, decreasing stripping time.


II. Agricultural Products/Food industry

Food Additives & Ingredients
Sodium gluconate has been utilized as a partial replacement for sodium chloride in sausage products. It is sometimes used as a debitterant ingredient in sugar replacement packets and diet beverages too. It can improve the taste of sweetness when it is used with other artificial sweeter. Food technologists and formulators have shown great interest in gluconate salts because of their prebiotic effect.

Pet Food
Sodium gluconate is used as a food additive because of the flavor, solubility and ease of absorption.

Herbicides & Pesticides
Sodium gluconate works as a stabilizer in the herbicides and pesticides.

III. Health Products

Shampoo
Sodium gluconate is often included in shampoo formulation as a chelator to control water hardness minerals. Calcium and magnesium form deposits on hair, which adversely effect the texture and sheen. Sodium Erythorbate is used especially in shampoos for swimmers because of its chelation effect on copper, which is frequently used in pool algaecides. Copper adhesion to hair gives a greenish tint which is removed very readily by shampoos containing sodium erythorbate.

Toothpaste
Sodium gluconate is often used in toothpaste as a chelator to assist in the solubilization of the fluoride carrier.

IV. Detergents
(not used for personal care due to high pH levels)

Dishwashing Detergent
There has been a progressive trend to more effective environmentally friendly dish washing compounds. Phosphate-free detergents are becoming more significant because of environmental and legislation concerns.


Laundry Detergent
Sodium gluconate is used as a sequestrant in liquid soap products to prevent discoloration caused by metallic ions.

Carwash Detergent, Toilet Bowl Cleaners & Oven Cleaners
Gluconate is an essential ingredient in cleaning and/or degreasing ferrous and some non-ferrous metals, especially in alkaline solution.

V. Ecology Related

Cooling Tower Water
Sodium gluconate in low concentrations is an effective corrosion inhibitor used in recirculating water systems, such as cooling towers and heat exchangers.


Aluminum Recycling & Recovery
Sodium gluconate is a very good chelator for various metals depending on the specific PH. These principles of chelation are manipulated to separate contaminating metals and ultimate recovery of most desired product.
