Ingabe i-sodium benzoate iphephile esikhumbeni

I-Sodium benzoate njengesivikeloisetshenziswa kabanzi embonini yokudla namakhemikhali futhi ngezinye izikhathi isetshenziswa ezimonyweni noma emikhiqizweni yokunakekela isikhumba. Kodwa ingabe ukuxhumana ngqo nesikhumba kuyingozi? Ngezansi, i-SpringChem izokuhambisa ohambweni lokuthola.

I-sodium benzoatenjengoba isilondolozi sinomphumela omuhle wokuvimbela amabhaktheriya kanye nesikhunta ngaphansi kwezimo ze-alkaline futhi singenye yezivikelo ezisetshenziswa kakhulu ezimbonini eziningi. I-pH engcono kakhulu yokugcina imvelo ingu-2.5-4.0. Ku-pH 3.5, sinomphumela omkhulu wokuvimbela ezinhlobonhlobo zezinambuzane ezincane; ku-pH 5.0, ikhambi alisebenzi kahle ekubulaleni amagciwane.

Isixazululo samanzi saso si-alkaline futhi uma inani elincane livezwa ku-sodium benzoate, ngeke libangele umonakalo osobala esikhumbeni. Kodwa-ke, kubantu abanesikhumba esibucayi, ukuvezwa kakhulu kuso noma isixazululo saso samanzi kungabangela umuzwa othile wokushisa esikhumbeni sendawo, futhi kungabangela ngisho namazinga ahlukahlukene okubomvu kwesikhumba sendawo, ukushisa, ukulunywa, ukuqubuka, noma ngisho nokulimala kwezilonda kanye neminye imonakalo, futhi ezimweni ezimbi kakhulu kungabangela ubuhlungu besikhumba esishisayo.

I-Sodium benzoate i-lipophilic futhi ingena kalula ezithweni zamangqamuzana ukuze ingene emangqamuzaneni, iphazamisa ukungena kwezicubu zamangqamuzana, ivimbela ukumuncwa kwama-amino acid yizicubu zamangqamuzana, ivimbela umsebenzi wama-enzyme okuphefumula kwamaseli, ivimbela ukusabela kokuminyana kwama-acetyl coenzymes futhi ivimbele umsebenzi wama-microorganisms, ngaleyo ndlela ikhonza injongo yokulondolozwa komkhiqizo. Ngemva kokuchayeka isikhathi eside noma ukugwinya inani elikhulu eliqukethe lokhu, kungalimaza nesimiso sezinzwa somuntu futhi kungabangela ngisho nokusebenza ngokweqile ezinganeni.

I-sodium benzoate nayo inobuthi obungavimba ukwakheka kweseli futhi ingabangela ukungasebenzi kahle kwe-membrane yamangqamuzana, kanye nokuqhekeka kweseli, okuholela ekuphazamisekeni kwezindlela ze-homeostasis yamangqamuzana, futhi ingabangela ngisho nomdlavuza ngokuchayeka isikhathi eside.

Imiphumela ye-sodium benzoate esikhumbeni

Ukwengezwa okuphezulu okuvunyelwe ezimonyweni zobuhle kungu-0.5% futhi kuyisithiyo esivunyelwe sokusetshenziswa kwezimonyo ku-Safety and Technical Specification for Cosmetics 2015 Edition eShayina.

I-Sodium benzoate inomthelela othile emzimbeni womuntu, kodwa ukusetshenziswa okulula kwemikhiqizo yokunakekela isikhumba, njengokhilimu wezandla, izimonyo, okhilimu bokuvimbela, njll., kuphela ngokusetshenziswa kwangaphandle kwesikhumba ngokuvamile akuthinti umzimba womuntu, ungakhathazeki kakhulu. Kunconywa futhi ukugwema ukusebenzisa imikhiqizo eminingi yokunakekela isikhumba nsuku zonke uma unezinkinga zesikhumba ezibangelwa ukungezwani komzimba noma uma unesikhumba esibi.

Nakubai-sodium benzoate ephephileUma ixutshwe ne-vitamin C, ingakhiqiza i-benzene ebangela umdlavuza kubantu. Uma usebenzisa imikhiqizo yokunakekela isikhumba ye-vitamin C, zama ukungayihlanganisi nezinye izinto ukuze ugweme ukulimala kwesikhumba sakho.

Izenzo Nemiphumela ye-Sodium Benzoate

I-Sodium benzoate ingasetshenziswa futhi njengesivikelo emithini yokusetshenziswa kwangaphakathi futhi inomphumela wokuvimbela ukonakala, kanye ne-asidi kanye nokwandisa isikhathi sokuphila kwayo. Uma inani elincane layo lingena emzimbeni, liyaguqulwa futhi alibangeli umonakalo emzimbeni. Kodwa-ke, i-sodium benzoate eningi ethathwa ngaphakathi isikhathi eside ingalimaza isibindi futhi ibangele nomdlavuza. Abantu abaningi badla kakhulu, okungangena ngokujulile kuzo zonke izicubu zomzimba ngemifantu yesiguli, ngakho-ke ukusetshenziswa isikhathi eside kungaholela kumdlavuza futhi kuyingozi kakhulu. Ukukhathazeka ngobuthi bayo kuye kwanciphisa ukusetshenziswa kwayo eminyakeni yamuva nje, futhi amanye amazwe afana neJapan ayekile ukukhiqiza i-sodium benzoate futhi abeke imingcele ekusetshenzisweni kwayo.
