|Product name: ||Benzoic Acid|
|Molecular Formula:||C7H6O2 |
Benzoic acid is a white or almost white, crystalline powder or colourless crystals. It is slightly soluble in water, soluble in boiling water, freely soluble in ethanol (96 per cent) and in fatty oils.
Benzoic acid is a preservative primarily for use against molds and yeasts, white crystals or powder, commonly used in food industry. In acidic condition, it has inhibitory effect, the optimum pH value is 2.5-4.0. Benzoic acid is used in concentrations of 0.05 to 0.1 percent. Due to the low solubility of benzoic acid and use shall be stirring, or dissolved in a small amount of hot water or ethanol, it is often used in the sodium salt.
