I-Methyl Paraben isetshenziswa kakhulu njengesivimbeli se-bactericidal ku-organic synthesis, ukudla, izimonyo, imithi, kanye nanjengesilondolozi sokudla.Sebenzisa isivikeli; Ama-antimicrobial agents.Sebenzisa: asetshenziswa njengesilondolozi, futhi asetshenziswa kwezokwelapha kanye ne-organic synthesis, esetshenziswa njengokudla, izimonyo kanye ne-pharmaceutical mildew inhibitor.
Isetshenziswa: isetshenziswa njenge-antiseptic kanye ne-bactericide embonini yezemithi, futhi njengesengezo sokuqeda ukugqwala ekuhlanganiseni okuphilayo nokudla, izinongo, amafilimu, njll. Imikhiqizo efanayo ekhiqizwa ngezindlela ezifanayo zokukhiqiza, i-ethyl p-hydroxybenzoate (Nipagin b) ne-propyl I-p-hydroxybenzoate (i-Nipagin C), nayo iyimithi yokubulala amagciwane kanye ne-antiseptic. Lo mkhiqizo uyacasula esikhumbeni. Sebenzisa: i-antiseptic ne-bactericide. Izinga lesiko lamaseli ezinambuzane lisetshenziselwa ukutadisha i-biosynthesis yamahomoni e-steroid, njenge-testerone. Sebenzisa: i-antiseptic ne-antiseptic. Ucwaningo nge-steroid hormone synthesis.
