I-sodium benzoate njenge-preservativeisetshenziswa kakhulu ezimbonini zokudla namakhemikhali futhi kwesinye isikhathi isetshenziswa ezimonyoni noma emikhiqizweni yokunakekela isikhumba.Kodwa ingabe ukuthintana ngqo nesikhumba kuyingozi?Ngezansi, i-SpringChem izokuthatha ohambweni lokuthola.

I-sodium benzoatenjengesivimbeli sinomphumela omuhle wokuvimbela ngokumelene namagciwane kanye nesikhunta ngaphansi kwezimo ze-alkaline futhi ingenye yezivimbeli ezisetshenziswa kakhulu ezimbonini eziningi.I-pH engcono kakhulu yokulondoloza yi-2.5-4.0.Ku-pH 3.5, inomphumela obalulekile wokuvimbela ezinhlobonhlobo zama-microorganisms;ku-pH 5.0, isixazululo asisebenzi kakhulu ekubulaleni inzalo.
Isixazululo saso samanzi sine-alkaline futhi uma inani elincane sivezwa ku-sodium benzoate, ngeke kubangele umonakalo osobala kakhulu esikhumbeni.Kodwa-ke, kubantu abanesikhumba esizwelayo, inani elikhulu lokuchayeka kuso noma isixazululo saso esinamanzi kungase kubangele ukuzwa okuthile okushisayo esikhumbeni sendawo, futhi kungase kubangele ngisho namazinga ahlukene okuba bomvu kwesikhumba, ukushisa, ukulunywa, ukuqubuka, noma izilonda kanye nezilonda. omunye umonakalo, futhi ezimweni ezimbi kakhulu kungase kubangele ubuhlungu besikhumba esivuthayo.
I-sodium benzoate iyi-lipophilic futhi ingena kalula kulwelwesi lwamangqamuzana ukuze ingene kumaseli, iphazamise ukungena kolwelwesi lwamangqamuzana, ivimbele ukumuncwa kwama-amino acid ngolwelwesi lwamangqamuzana, ivimbele ukusebenza kwama-enzyme okuphefumula kwamangqamuzana, ivimbele ukusabela kwe-condensation yama-acetyl coenzymes futhi ivimbele umsebenzi. ama-microorganisms, ngaleyo ndlela asebenze inhloso yokugcinwa komkhiqizo.Ngemva kokuchayeka isikhathi eside noma ukumunca izinto eziningi eziqukethe lokhu, kungase futhi kulimaze isimiso sezinzwa somuntu futhi kungase kubangele nokunganyakazi kahle ezinganeni.
I-sodium benzoate nayo iyi-cytotoxic futhi ingase ibangele ukungasebenzi kahle kolwelwesi lwamangqamuzana, kanye nokuphuka kweseli, okuholela ekuphazamisekeni kwezinqubo ze-homeostasis zamaselula, futhi ingase ibangele nomdlavuza ngokuchayeka isikhathi eside.
Imiphumela ye-sodium benzoate esikhumbeni
Isilinganiso esiphezulu esivunyelwe sokwengezwa kwezimonyo singu-0.5% futhi siyisilondolozi esivunyelwe sokusetshenziswa kwezimonyo ku-Safety and Technical Specification for Cosmetics Edition yango-2015 e-China.
I-sodium benzoate inomphumela othile emzimbeni womuntu, kodwa ukusetshenziswa okulula kwemikhiqizo yokunakekelwa kwesikhumba, njengama-creams ezandla, izimonyo, ama-barrier creams, njll., ngokusebenzisa ukusetshenziswa kwangaphandle kwesikhumba ngokuvamile akuthinti umzimba womuntu, ukukhathazeka kakhulu.Kuyafaneleka futhi ukugwema ukusebenzisa imikhiqizo eminingi yokunakekelwa kwesikhumba nsuku zonke uma unezimo zesikhumba ezingezwani nezimo noma uma unesikhumba esibuthakathaka.
Nakubai-sodium benzoate iphephileesikhumbeni, uma ixubene novithamini C, ingakhiqiza i-benzene ye-carcinogen yomuntu.Uma usebenzisa imikhiqizo yokunakekela isikhumba kavithamini C, zama ukungayigqizi ngezinye izinto ukuze ugweme ukulimala esikhumbeni sakho.
Izenzo Nemiphumela Ye-Sodium Benzoate
I-sodium benzoate ingasetshenziswa futhi njengesilondolozi emithini yemithi enguketshezi ukuze isetshenziswe ngaphakathi futhi inomphumela wokuvimbela ukubola, kanye ne-asidi nokwelula impilo yeshalofu.Lapho amanani amancane awo engena emzimbeni, ayagaywa futhi awabangeli umonakalo emzimbeni.Nokho, i-sodium benzoate eyeqile ethathwe ngaphakathi isikhathi eside ingalimaza isibindi futhi ibangele nomdlavuza.Abantu abaningi badla kakhulu, okungangena kujule kuzo zonke izicubu zomzimba ngokusebenzisa izimbotshana zesiguli, ngakho ukusetshenziswa isikhathi eside kungaholela kumdlavuza futhi kuyingozi kakhulu.Ukukhathazeka ngobuthi bayo kukhawule ukusetshenziswa kwayo eminyakeni yamuva, futhi amanye amazwe anjengeJapane ayekile ukukhiqiza i-sodium benzoate futhi abeka imingcele ekusetshenzisweni kwayo.
