Kutheni usebenzisa ibenzoic acid? Umsebenzi we-benzoic acid:
(1) Ukuphucula ukusebenza kweehagu, ngokukodwa ukusebenza kakuhle kokuguqulwa kwesondlo
(2) Isilondolozi; I-agent ye-Antimicrobial
(3) Isetyenziswa kakhulu kwi-antifungal kunye ne-antiseptic
(4) I-Benzoic acid luhlobo olubalulekileyo lwe-asidi yokutya
I-Benzoic acid kunye neetyuwa zayo zisetyenziswe iminyaka emininzi njengento yokugcina
kushishino lokutya, kodwa kwamanye amazwe njengezongezo zesilege, ikakhulu ngenxa yokusebenza okuqinileyo kwazo ngokuchasene neentlobo ezahlukeneyo zokungunda kunye negwele.
