What Is Sodium gluconate?

Sodium gluconate, also called gluconolactone, is a naturally occurring sodium salt of gluconic acid.[1,2]

What Does Sodium gluconate Do in Our products?

Sodium gluconate is a skin-conditioning agent that is also a chelating agent commonly used in household cleaning products.[3,4] It is often found in bar soap, sunscreen, shampoo, toothpaste, hair products, makeup and a variety of other products as well.[5] We use it in our dishwasher detergent.

Why Puracy Uses Sodium gluconate

Sodium gluconate is a surfactant and chelating agent that helps prevent hard-water stains.[7,8] Whole Foods has deemed the ingredient acceptable in its body care and cleaning product quality standards.[9,10] The National Institutes of Health report that the ingredient is not a skin or eye irritant, and the FDA has deemed it Generally Recognized as Safe.[11,12,13]

How Sodium gluconate Is Made

Commercially, manufacturing sodium gluconate involves neutralizing gluconic acid with a sodium base or by acidifying calcium gluconate with sulfuric acid, filtering the product and neutralizing the result with a sodium base. Other methods involve continuous neutralization of gluconic acid formed during submerged culture fermentation.[6]
