I-Benzalkonium Chloride: Idlala indima ephambili ekubulaleni iintsholongwane

Ngo-Agasti 2024, ngokwandiswa kolwazi ngempilo yehlabathi, imakethi yokubulala iintsholongwane iye yamkela amathuba amatsha ophuhliso. Phakathi kwawo, i-benzalkonium chloride, njengesibulali-ntsholongwane esisebenza kakuhle nesibanzi, itsale ingqalelo enkulu ngenxa yeenzuzo zayo ezikhethekileyo.

1. I-Benzalkonium chloride luhlobo lwesibulali-ntsholongwane setyuwa ye-quaternary ammonium salt esine-chain enye. Ngenxa yeempawu zayo ezifana nokuzinza okuhle, ukungabi natyhefu, kunye nokungacaphukisi, iye yaba yindawo ephambili yophando kwiminyaka yakutshanje. Ayinakubulala kuphela iintsholongwane kunye nefungi kodwa ikwayivala intsholongwane, kwaye isetyenziswa kakhulu kwiindawo ezifana nokubulala iintsholongwane kulusu kunye nokusingqongileyo. Okwangoku, i-benzalkonium chloride ivunyiwe yi-National Medical Products Administration (NMPA) ukuba isetyenziswe kumalungiselelo ahlukeneyo afana namabala, izisombululo, izitshizi, kunye namaconsi amehlo.

2. Indlela yokubulala iintsholongwane ye-benzalkonium chloride ikakhulu ixhomekeke ekutshintsheni ukuvuleka kwe-cytoplasmic membrane, okubangela ukuphuma kwezinto ze-cytoplasmic zebhaktheriya, ngaloo ndlela ithintela imetabolism yazo kwaye idlale indima yokubulala. Nangona inefuthe elinamandla kwi-Gram-positive bacteria kunye nefuthe elibuthathaka kwi-Gram-negative bacteria ezifana nePseudomonas aeruginosa, ayisebenzi ngokupheleleyo kwiMycobacterium tuberculosis kunye ne-bacterial spores. Nangona kunjalo, kwizicelo ezisebenzayo, i-benzalkonium chloride isasebenza kakuhle. Ingakumbi, uphawu lokuba isiphumo sayo sinciphile kakhulu xa kukho igazi, umqhaphu, i-cellulose, kunye nezinto eziphilayo lukwenza ukusetyenziswa kwayo kukhuseleke kwiimeko ezithile.

3. Ngaphandle kwezicelo zayo kwicandelo lezonyango, i-benzalkonium chloride ikwasetyenziswa kakhulu ekubulaleni iintsholongwane kwimizi-mveliso. Njenge-fungicide engafaki i-oxidizing, inokulawula ngempumelelo ukuzala kweebhaktheriya kunye ne-algae kunye nokukhula kwe-slime emanzini, kwaye inefuthe elihle lokuhluza i-slime kunye nemiphumo ethile yokusasazeka kunye nokungena. I-Benzalkonium chloride idlala indima ebalulekileyo kwimimandla efana namanzi okupholisa ajikeleza umzi-mveliso, amanzi ezityalo zamandla, iifektri zamaphepha, kunye neenkqubo zokujova i-oilfield well.

Ngenxa yenkqubela phambili yesayensi netekhnoloji kunye nokwanda okuqhubekayo kwemfuno yabantu yococeko, amathuba emarike ye-benzalkonium chloride aya kuba maninzi nangakumbi. Iingenelo zayo ezizodwa kunye neempawu zayo ezininzi zenza ukuba ibe ngumdlali opheleleyo kwicandelo lokubulala iintsholongwane, inegalelo elibalulekileyo kuphuhliso lweenkqubo zempilo zehlabathi.
