Usage:
1. Strong inhibition of p-hydroxybenzoic acid esters of molds and yeasts, bacteria especially for lactic acid bacteria and gram negative bacteria effect is poor, but the antibacterial ability than sorbic acid and benzoic acid is strong, and the antibacterial effect is not affected by PH, in the range of PH4-8 effect is good.
2. Strong inhibition of p-hydroxybenzoic acid esters of yeasts and molds, bacteria especially poor effect of lactic acid bacteria and gram negative bacilli, but antibacterial ability than sorbic acid and benzoic acid is strong, and the antibacterial effect is affected by the pH value is small, the pH value of 4 ~ 8 range effect is good.
3. Preservative. Many countries use the ethyl and propyl, but the Japanese often make the butyl. Because it is difficult to dissolve in water, so often the esters with.
4. Organic intermediates. Used as an antiseptic, antibacterial agent, used in the food, cosmetic, pharmaceutical products. Also can be used as organic analytical reagents. The product of the mold, yeast and bacteria have a wide range of antibacterial action, the mould and yeast is stronger, but bacteria especially poor effect on Gram negative bacteria and lactic acid bacteria. Is efficient and antiseptic in food and medicine.
