Sodium benzoateNjengokulondolozwa kunomthelela omuhle wokuvimbela ukumelana namagciwane kanye nesikhunta ngaphansi kwezimo ze-alkali futhi kungenye yezindawo ezisetshenziswayo ezisetshenziselwa izimboni eziningi. I-PH engcono kakhulu yokulondolozwa yi-2,5-4.0. Ku-PH 3.5, inomphumela omkhulu wokuvimbela ezinhlobonhlobo ezihlukene ama-microorganisms; Ku-PH 5.0, ikhambi alisebenzi kahle kakhulu ekuhlanzeni inzalo.
Isixazululo esinamanzi sawo yi-alkaline futhi uma inani elincane livezwa ku-sodium benzoate, ngeke kubangele ukulimala okusobala esikhunjeni. Kodwa-ke, kubantu abanesikhumba esibucayi, inani elikhulu lokuchayeka kulo noma ikhambi layo elinamanzi lingadala umuzwa othile ovuthayo esikhunjeni sendawo, futhi kungadala ngisho namazinga ahlukahlukene okubomvu kwesikhumba sendawo, futhi kungahle kudale amazinga ahlukahlukene okubomvu, noma ngisho nezilonda, futhi ezimweni ezinzima kungadala ubuhlungu besikhumba esivuthayo.
I-sodium benzoate i-lipophilic futhi ingena kalula ulwelwesi lwamaseli ukungena kumaseli, kuphazamisa ukufakwa kwama-membranes cell, kuvimbela ukusatshalaliswa kwama-acidi amaselula, kuvimbela umsebenzi we-acetyl coenzymes futhi uvimbela umsebenzi we-microorganisms, ngaleyo ndlela ukhonze injongo yomkhiqizo ukulondolozwa. Ngemuva kokuvezwa isikhathi eside noma ukufakwa kwamanani amakhulu aqukethe lokhu, kungalimaza nohlelo lwezinzwa lwabantu futhi kungadala ngisho nokungcwabe ezinganeni.
I-sodium benzoate nayo i-cytotoxic futhi ingadala ukungasebenzi kahle kwamaseli, nokuqhamuka kwamaseli, okuholela ekuphazamisweni kwezindlela zokuxhumana zamaselula, futhi kungahle kubangele umdlavuza ngokuvezwa isikhathi eside.
Imiphumela ye-sodium benzoate esikhunjeni
Ukungezwa okuphezulu okuvunyelwe kwezimonyo kungu-0,5% futhi kungukulondolozwa okuvunyelwe kokusetshenziswa kwezimonyo ekuphepheni nasekucacisweni kwezobuchwepheshe kwezimonyo ze-cosmetics 2015 edition eChina.
I-sodium benzoate inomphumela othile emzimbeni womuntu, kepha ukusetshenziswa okulula kwemikhiqizo yokunakekelwa kwesikhumba, okufana nokhilimu wezandla, izimonyo, okhilimu wangaphandle, njll. Kungcono futhi ukugwema ukusebenzisa imikhiqizo eminingi yokunakekelwa kwesikhumba nsuku zonke uma unezimo zesikhumba se-allergic noma uma unesikhumba esingesihle.
NokhoI-sodium benzoate iphephileesikhunjeni, lapho kuxutshwe ne-vithamini C, kungakhiqiza i-carcinogen benzene yabantu. Uma usebenzisa imikhiqizo yokunakekelwa kwesikhumba yeVitamin C, zama ukungawahlukani nezinye izinto ukuze ugweme ukulimala kwesikhumba sakho.
Izenzo ze-sodium benzoate nemiphumela
I-sodium benzoate ingasetshenziswa futhi njengendawo yokugcina emikhakheni ewuketshezi yokusetshenziswa kwangaphakathi futhi inomphumela wokuvimbela ukonakala, kanye ne-acidity futhi kunwebe impilo yeshelufu. Lapho amanani amancane angena emzimbeni, ahlakazekile futhi awabangeli umonakalo emzimbeni. Kodwa-ke, ngokweqile i-sodium benzoate ethathwe ngaphakathi isikhathi eside kungalimaza isibindi futhi kubangele umdlavuza. Abantu abaningi bangena kakhulu, engangena ekujuleni kuzo zonke izicubu zomzimba ngokusebenzisa ama-pores wesiguli, ngakho-ke ukusetshenziswa kwesikhathi eside kungaholela kumdlavuza futhi kuyingozi kakhulu. Ukukhathazeka nge-Forexity yayo kukhawulelwe ukusetshenziswa kwayo eminyakeni yamuva nje, kanti amanye amazwe anjengeJapan ayeke ukukhiqiza i-sodium benzoate futhi abeke imingcele ekusetshenzisweni kwawo.
