Hydrating Products (Glucono Delta Lactone)
Glucono Delta Lactone is used in these products as an alpha hydroxy acid (AHA). AHA’s are very mild acids that have been shown to have a very beneficial effect on skin
UV Absorber (Sodium Erythorbate)
Sodium erythorbate is used as a UV blocker in various sun blockers and lotions
Hair Coloring (Sodium Erythorbate)
Sodium erythorbate is used in hair coloring formulations as an antioxidant to help stabilize the colors and dyes.
(not used for “personal care” due to high pH levels)
Dishwashing Detergent (Sodium Gluconate; Gluconic Acid)
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. The European market has recognized the damaging effects of heavy phosphate use and has imposed very strict legislation. These regulations have provided the impetus for the development of several phosphate-free, gluconate containing products. The chelation properties combined with their low corrosion and ease of biodegradation have allowed gluconates to become an essential ingredient in the “green” dish washing compounds.
Laundry Detergent (Sodium Gluconate; Gluconic Acid)
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 (Sodium Gluconate; Gluconic Acid)
Gluconate is an essential ingredient in cleaning and/or degreasing ferrous and some non-ferrous metals, especially in alkaline solution. The sequestering function of gluconate in most metal washing operations is to prevent hard water ions, such as, calcium and magnesium from complexing with the alkali in the cleaner. If these hard water ions are allowed to react with alkali components, an insoluble complex will be precipitated. This undesirable precipitate can build up and deposit itself causing damage to the cleaning vessel and surface to be cleaned.
Cooling Tower Water (Sodium Gluconate)
Sodium gluconate in low concentrations is an effective corrosion inhibitor used in recirculating water systems, such as cooling towers and heat exchangers.
These systems are composed of pipes, vessels, etc. constructed of copper and carbon steels which are particularly prone to oxidative corrosion. This occurs because air from the atmosphere will dissolve in the cooling water. The dissolved oxygen will diffuse into the metal inducing corrosion. The corrosion can be inhibited by dissolving sodium gluconate in a certain concentration.
Recovering Precious Metals from Computer Waste (Sodium Erythorbate)
In these application sodium erythorbate is used as a metal reducing agent to assist in the separation and recovery of the individual metals.
Aluminum Recycling & Recovery (Sodium Gluconate)
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.
