Sei kushandisabenzoic acid? Benzoic Acid Basa:
(1) Kuvandudza kushanda kwenguruve, kunyanya kushanda kwekushandura kwekudya
(2) Chekuchengetedza; Antimicrobial agent
(3) Inonyanya kushandiswa kune antifungal uye antiseptic
(4) Benzoic asidhi yakakosha asidhi mhando yekudyisa kuchengetedza
Benzoic acid nemunyu wayo zvakashandiswa kwemakore akawanda sekuchengetedza
vamiririri neindasitiri yechikafu, asi mune dzimwe nyika zvakare sezvinowedzera silage, zvakanyanya nekuda kwesimba ravo rekuita kurwisa fungi dzakasiyana uye mbiriso.
