Benzoic acid, sodium salt

Description:
Benzoic acid, sodium salt, commonly known as sodium benzoate, is a white, crystalline powder that is the sodium salt of benzoic acid. It is highly soluble in water and exhibits a slightly sweet taste. Sodium benzoate is widely used as a food preservative due to its ability to inhibit the growth of mold, yeast, and some bacteria, particularly in acidic conditions. Its effectiveness as a preservative is enhanced at lower pH levels, making it suitable for acidic foods and beverages. In addition to its role in food preservation, sodium benzoate is utilized in various industrial applications, including cosmetics, pharmaceuticals, and as a corrosion inhibitor. It is generally recognized as safe (GRAS) when used in appropriate concentrations, although excessive intake may lead to potential health concerns. Sodium benzoate can also participate in chemical reactions, such as forming benzoic acid upon acidification. Overall, its properties and applications make it a versatile compound in both food science and industrial chemistry.

    Sodium benzoate

    CAS:

    Sodium benzoate is a food additive that is used as an antimicrobial agent and preservative. It has been shown to have synergistic effects when combined with sodium citrate for the treatment of cancerous skin lesions in mice. This synergistic effect has also been observed using electrochemical impedance spectroscopy on mitochondria from rat brain cells. Sodium benzoate has also been found to inhibit the production of neurotrophic factors such as nerve growth factor and brain-derived neurotrophic factor, which are required for neuronal development. Sodium benzoate can be used to identify DNA mutations by fluorescence probe labeling and synchronous fluorescence imaging.
