It can be found in cleaning agents for glass bottles and as a chelating agent in various cleaning formulations. Gluconates are added to cleansers and shampoos to increase the lather by sequestering hard water ions. Gluconates are also used in oral and dental care products such as toothpaste where it is used to sequester calcium and helps to prevent gingivitis.
Manufacture Process of Gluconic Acid
Only the production of sodium gluconate by batch submerged fermentation from glucose syrups, using A. niger is described in this article. Glucose syrups of 70°Brix strength are generally used as the carbon sources in the preparation of the fermentation medium.
The pH is first adjusted to 4.5 with sulphuric acid, and then the medium is sterilized at 121°C for 15–30 min, cooled to 33°C, and charged into the fermentation vessel. The pH is then raised to 6–6.5 with sodium hydroxide. A 2–5% inoculum is generally used. For the development of the inoculum, conidia are recovered from the stock agar slants and inoculated into vegetative seed culture medium (106 conidia per cubic centimetre). After incubation at 30°C for 15–24 h, pellet-like mycelia are obtained and used to inoculate the seed fermenters at a concentration of 20–50 pellets per cubic centimetre.
Fermentation is carried out with continuous automatic control of: the sterile air flow rate (1.0–1.5 vv−1 min−1), the temperature (33°C); the pressure on the top of the tank (2–3 bar); the pH (5.5–6.5); and the foam level. The pH is controlled by the addition of 30–50% NaOH solution, to neutralize the gluconic acid formed. The fermentation is complete within about 30 h, with yields of 0.97–1 kg of gluconic acid per kilogram of glucose consumed (the theoretical yield being 1.09 kg kg−1) and gluconate productivities of 9–13 kg m−3 h−1.
In fed-batch fermentations, the mycelium can be reused up to five times without loss of gluconate productivity, provided that the activity of glucose oxidase and the levels of micronutrients (i.e. iron and manganese) are kept under control. The recovery of the mycelium can be performed by allowing the mycelium to form a sediment at the bottom of the vessel in the absence of agitation and aeration, by aseptic centrifugation or by cross-flow microfiltration. The stepwise addition of glucose may increase the gluconate concentration in the fermented broth to 580 kg m−3.
At the end of fermentation, the mycelium is removed using continuous vacuum belt filters and may be used as a source of glucose oxidase or disposed via incineration. The clarified broth, generally containing ca. 300 kg m−3 sodium gluconate, is filtered, decolorized using a granular activated-carbon column, concentrated under vacuum to 45–50% total solids, neutralized to pH 7.5 with NaOH, and then spray- or drum-dried.
If 50% gluconic acid is required, the concentrated liquor may be passed through a cation-exchanger to remove Na+ ions. Further crystallization at 30–70°C or >70°C allows crystals of the δ-lactone or γ-lactone to be precipitated, respectively.
The method relates to a method for measuring content of sodium gluconate in a sodium gluconate mother solution. The problem that the content of sodium gluconate in the sodium gluconate mother solution cannot be rapidly and accurately measured is effectively solved. The method comprises the following steps
- Measuring the solid content and reduzate content of the sodium gluconate mother solution, and measuring the density of the sodium gluconate mother solution
- Treating the sodium gluconate mother solution, wherein the treatment method comprises the following sub-steps:
- Adding a sodium hydroxide solution into the sodium gluconate mother solution, uniformly mixing, adding a copper sulfate solution, boiling, cooling to room temperature, and adding water to reach the constant volume;
- Adding distilled water into analytically pure sodium gluconate to be dissolved into a 0.05mol/L sodium gluconate standard solution; drawing a standard curve of the sodium gluconate standard solution;
- Measuring the content of sodium gluconate in the sodium gluconate mother solution according to a formula, so that the content of the sodium gluconate in the sodium gluconate mother solution is measured.
How is Sodium Gluconate Used in Soap
Sodium gluconate (SG) is a chelator. It offers two benefits when used in soap and other personal care products -- It increases the shelf life of your soap by chelating (binding up) certain metals that can cause DOS (dreaded orange spots, also known as rancidity). It also reduces the amount of sticky soap scum formed when lye-based soap is used in hard water.
Sodium gluconate, tetrasodium EDTA, and citrate all do similar jobs. If one does not appeal or is not available to you, then consider using one of the others. SG appears to be as or more effective than EDTA according to one manufacturer. This effectiveness is supported by anecdotal reports from soap makers.
Sodium gluconate is manufactured as a powder at 98-99% purity. It is also sold as a water-based liquid containing up to 60% SG by weight as well as a preservative. The best way to ensure your sodium gluconate stays as effective as possible is to measure the SG powder directly into each batch. It dissolves easily in water-based liquids.
A compromise would be to make only enough SG solution needed for the current day of soap making and discard any leftover solution at the end of the day. Sodium gluconate is highly soluble in water, so it would be reasonable to make a 50% masterbatch -- 50 grams of SG dissolved in 50 grams of distilled water. It might also be wise to also add a broad-spectrum, water-based preservative to discourage bacteria and fungi.
Soap makers who use sodium gluconate typically use 0.5% to 1% SG powder based on total batch weight. This is 5 to 10 grams SG powder per 1000 g of total batch weight (oil weight + water weight + alkali weight). A dose of 0.5% seems to be a commonly used rate for soap. One cosmetics supplier recommends using SG from 0.1% to 1.0% in personal care products, which include soap, lotion, shampoo, etc. so a 0.5% dose seems reasonable.
