Benzoic acid and its salts are used as food preservatives, represented by the E numbers E210, E211, E212, and E213. Benzoic acid inhibits the growth of mold , yeast [ 23 ] and some bacteria . It is either added directly or created from reactions with its sodium , potassium , or calcium salt.
Although the maximum rate of biotransformation of benzoic acid to hippuric acid varied between 17.2 and 28.8 mg.kg-1.h-1 among the six individuals, the mean value (23.0 mg.kg-1.h-1) was fairly close to that provided by daily maximum dose (0.5 g.kg-1.day-1) recommended in the treatment of hyperammonaemia in patients with inborn errors of ureagenesis
The original ointment contains 3% salicylic acid and 6% benzoic acid in a suitable base, such as lanolin or petrolatum. [2] [3] Alternatively, a short-chain alcohol or fatty alcohol can be used as the base. [4]
Potassium benzoate (E212), the potassium salt of benzoic acid, is a food preservative that inhibits the growth of mold, yeast and some bacteria.It works best in low-pH products, below 4.5, where it exists as benzoic acid.
Across a sample of 23 nicotine salts available for public purchase, the three most common acids used in the formation of nicotine salts were lactic acid, benzoic acid and levulinic acid. [8] Benzoic acid is the most used acid to create a nicotine salt. [9] Nicotine pyruvate is another form of nicotine salt. [10] A chemical reaction with a ...
4-Hydroxybenzoic acid, also known as p-hydroxybenzoic acid (PHBA), is a monohydroxybenzoic acid, a phenolic derivative of benzoic acid.It is a white crystalline solid that is slightly soluble in water and chloroform but more soluble in polar organic solvents such as alcohols and acetone. 4-Hydroxybenzoic acid is primarily known as the basis for the preparation of its esters, known as parabens ...
Benzalkonium chloride is a frequently used preservative in eye drops; typical concentrations range from 0.004% to 0.01%. [17] Stronger concentrations can be caustic [18] and cause irreversible damage to the corneal endothelium. [19] Avoiding the use of benzalkonium chloride solutions while contact lenses are in place is discussed in the literature.
Ammonium benzoate, a white powder-like substance, is the ammonium salt of benzoic acid. [1] This compound is prepared by the reaction of benzoic acid and ammonia.
