Product performance

 Benzoic acid has a melting point of 122.13 ° C, a boiling point of 249 ° C,

and a relative density of 1.2659 (15/4 ° C). It rapidly sublimes at 100 ° C, its vapor is very irritating,

and it is easy to cause cough after inhalation.

Slightly soluble in water, soluble in organic solvents such as ethanol and ether.

Benzoic acid is a weak acid and stronger than fatty acids.

Product Usage

Benzoic acid can be used as a preservative for food, feed, latex, and toothpaste.

Under acidic conditions, it has inhibitory effects on mold, yeast and bacteria, but it has weak effect on acid-producing bacteria.

The bacteriostatic activity of the benzoic acid molecular state is higher than that of the ionic state. Therefore, when the pH is less than 4, the bacteriostatic activity is high, and the suitable pH for the bacteriostatic action is 2.5 to 4.0, and generally lower than the pH value of 4.5 to 5.0.

Decorating agent

Benzoic acid can be used as a fixative for juice drinks.

It can be used as a cream to add aromatherapy essence.

It can also be used in food flavors such as chocolate, lemon, orange, berry, nut, candied fruit.

It is also commonly used in tobacco flavors.

Due to the low solubility of benzoic acid, it must be thoroughly stirred or dissolved in a small amount of hot water or ethanol.

When used in concentrated juice for refreshing beverages, since sodium benzoate easily volatilizes with water vapor, its sodium salt is often used.
