Kenyelletso ea Sehlahisoa

Methyl 4-hydroxybenzoate ke lintho tse phelang. Ka lebaka la sebopeho sa eona sa phenolic hydroxyl, e na le thepa ea antibacteria e betere ho feta benzoic acid le sorbic acid. Mosebetsi oa paraben o bakoa haholo ke boemo ba limolek'hule, 'me sehlopha sa hydroxyl ka molek'hule se entsoe esterified' me ha se sa hlola se e-na le ionized. Ka hona, e na le phello e ntle sebakeng sa pH 3 ho ea ho 8. Ke ntho e sa sebetseng ea lik'hemik'hale 'me e bonolo ho lumellana le lintho tse sa tšoaneng tsa lik'hemik'hale.
