説明
Sodium gluconate is the organic sodium salt of gluconic acid. Sodium gluconate is a chelator that forms stable complexes with various ions and ultimately prevents these ions from engaging in chemical reactions. Gluconates are naturally occurring substances that freely dissociate to the gluconate anion and its respective cations. Being fully biodegradable and non-toxic, it represents an environment friendly alternative to the common chelating agents used in cosmetics such as EDTA. In addition to this, sodium gluconate has a low acute toxicity to aquatic organisms.
化学的特性
Sodium gluconate is a white to tan, granular to fine, practically odourless crystalline powder. It is very soluble in water, sparingly soluble in alcohol and insoluble in ether.
使用
Sodium gluconate is used as a natural preservative. It prevents the growth of microbes in our products to keep them safe for our consumers. It also works as a skin-conditioning agent and a chelating agent which helps cleansing products to foam better in hard water. You can often find sodium gluconate in soap, sunscreen, shampoo, toothpaste, hair products, makeup, and a variety of other personal care products.
Sodium gluconate has been used as a component of recording buffer used in two-electrode voltage-clamp (TEVC) recording in Xenopus laevis oocytes. It has also been used as a control for sodium.
定義
ChEBI: Sodium gluconate is an organic sodium salt having D-gluconate as the counterion. It has a role as a chelator. It contains a D-gluconate.
安全性プロファイル
Low toxicity by intravenous route. When heated to decomposition it emits acrid smoke and irritating fumes
純化方法
Crystallise it from a small volume of H2O (solubility is 59g/100mL at 25o), or dissolve it in H2O and add EtOH since it is sparingly soluble in EtOH. It is insoluble in Et2O. It forms a Cu complex in alkaline solution and a complex with Fe in neutral solution. [cf p 639, Sawyer & Bagger J Am Chem Soc 81 5302 1959, Beilstein 3 I 188.]
