Product Description
Acidifier
It is divided into organic acid, inorganic acid, and complex acidifier, which can improve the intestinal environment, increase the substance conversion rate, inhibit the harmful bacteria in the intestinal tract, and promote the growth of animals.
organic acid : benzoic acid
CAS 65-85-0
It is mainly used for anti-fungal and disinfection and anti-corrosion. It is used in the production of medicines, dye carriers, plasticizers, perfumes and food preservatives. It is also used for the performance improvement of alkyd resin coatings. It is also used as a rust inhibitor for steel equipment and agriculture. Chemicals.
Medical use
Benzoic acid can be used to prepare benzoic acid salicylic acid ointment. Benzoic acid salicylic acid ointment is prepared by adding lanolin and salicylic acid as main raw materials and adding lanolin and yellow Vaseline. Among them, benzoic acid combined with salicylic acid can treat adult dermatophytosis, superficial fungal infections such as body lice, hand lice and athlete's foot.
preservative
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 optimum pH value of the bacteriostatic is 2.5 to 4.0, and generally lower than the pH value of 4.5 to 5.0. Since the solubility of benzoic acid in water is low, it is actually added with an appropriate amount of sodium carbonate or sodium hydrogencarbonate, dissolved in hot water of 90 ° C or higher, and converted into sodium benzoate before being added to the food. If benzoic acid must be used, it can be dissolved after dissolving it in an appropriate amount of ethanol. Since benzoic acid has a lower solubility in water than sodium benzoate, when sodium benzoate is used in an acidic food, care should be taken to prevent precipitation due to conversion of sodium benzoate to benzoic acid and to reduce its use. Benzoic acid can be used together with p-hydroxybenzoic acid esters in soy sauces and refreshing beverages to increase efficiency.
