Umphumela weMethylparaben esikhumbeni: ukuhlaziya okuphelele
I-Methylparaben, eyaziwa nangokuthi i-methylparaben, isilondolozi esisetshenziswa kakhulu kuzimonyo, ukudla kanye nemithi. Kuye kwaba isithako esibalulekile emikhiqizweni eminingi ngenxa yezakhiwo zayo eziphumelelayo zokulwa namagciwane, kodwa lokhu kuye kwaholela ekuxoxweni okubanzi nokucwaninga ngemiphumela yayo esikhumbeni. Kuleli phepha, sizohlaziya ngokuningiliziwe imiphumela ethile ye-methyl hydroxyphenyl ester esikhumbeni futhi sixoxe ngokusetshenziswa kwayo embonini yezimonyo.
Izakhiwo Zamakhemikhali kanye Nezicelo ze-Methylparaben
I-Methyl hydroxyphenyl ester iyi-methyl ester ye-p-hydroxybenzoic acid, okungesinye sezivimbeli ezisetshenziswa kakhulu ze-paraben. Umsebenzi wayo oyinhloko ukunweba impilo yeshalofu yemikhiqizo ngokuvimbela ukukhula kwamabhaktheriya, imvubelo kanye nesikhunta. Ngenxa yezindleko eziphansi nokusebenza kwayo, i-methylparaben yengezwa kabanzi emikhiqizweni yokunakekelwa kwesikhumba, ama-shampoos, ama-lotions neminye imikhiqizo yokunakekelwa kwansuku zonke.
Imiphumela Emihle ye-Methylparaben Esikhumbeni
Isenzo sokulondoloza i-Methylparaben sivimbela ukungcoliswa kwamagciwane emikhiqizweni yezimonyo, ngaleyo ndlela kunciphise ingozi yokutheleleka okungenzeka esikhumbeni. Imikhiqizo engangcolisiwe inikeza okuhlangenwe nakho okuphephile esikhumbeni, ikakhulukazi kubantu abanesikhumba esibucayi, futhi ukusetshenziswa kwemikhiqizo efakwe i-preservative kungasiza ekugwemeni izinkinga zesikhumba ezibangelwa amagciwane noma isikhunta.
Ngenxa yokugcwala okuphansi kwe-Methylparaben esetshenziswa (imvamisa ngaphansi kuka-1%), ayinawo umthelela omubi obalulekile esikhumbeni sabantu abaningi. Ucwaningo oluningana lubonise ukuthi i-methylparaben iwukucasula isikhumba esiphansi ekugxilweni kokusetshenziswa okunqunyiwe futhi ayibangeli ukuzwela kwesikhumba noma okunye ukusabela okunamandla. Ngakho-ke, njengesilondolozi sendabuko nesifakazelwe kabanzi, i-methylparaben inikeza izinga lokuphepha komkhiqizo.
Imiphumela emibi engaba khona ye-methylparaben esikhumbeni
Nakuba i-Methylparaben iphephile kubantu abaningi ezindaweni eziphansi, kusenezifundo ezithile nemibiko ephakamisa ukuthi ingase ibe nemiphumela engemihle esikhumbeni. Ukusetshenziswa isikhathi eside kwemikhiqizo equkethe i-methylparaben kunamandla okuba nomthelela ekusebenzeni kwesithiyo sesikhumba, ikakhulukazi kubantu abanesikhumba esizwelayo noma esivele sonakele.
I-Methylparaben nayo isolwa ngokuthi ingase ibe nomsebenzi we-estrogenic obuthakathaka, futhi nakuba lokhu kungazange kuboniswe ngokucacile ukuthi kuyingozi eqondile empilweni yomuntu ngaphansi kokusetshenziswa okujwayelekile, abanye ochwepheshe besikhumba batusa ukuthi abesifazane abakhulelwe kanye nabantu abasengozini enkulu yomdlavuza webele kufanele bazame ukugwema ukusetshenziswa kwesikhathi eside kwemikhiqizo equkethe i-methylparaben.
Isetshenziswa kanjani imikhiqizo equkethe i-methylparaben ngokuphepha
Ukuqinisekisa impilo nokuphepha kwesikhumba, abathengi kufanele banake amaphuzu alandelayo lapho bekhetha imikhiqizo equkethe i-methylparaben: Khetha izinhlobo ezinkulu noma imikhiqizo enedumela elihle, njengoba le mikhiqizo ivamise ukuba nokulawulwa kwezithako okuqinile kanye nocwaningo lokwakheka. Naka imiyalo yokusebenzisa imikhiqizo ukuze ugweme ukudakwa ngokweqile noma ukusetshenziswa njalo. Abantu abanesikhumba esizwelayo kufanele bacabangele eminye imikhiqizo elondolozayo enobungozi obuncane bokungezwani komzimba nezinto ezithile, noma bakhethe imikhiqizo ye-skincare ebizwa ngokuthi “i-preservative-free” noma “egcinwe ngokwemvelo”.
Isiphetho
Umphumela we-methylparaben esikhumbeni uncike kakhulu ekugxilweni okusetshenzisiwe kanye nesimo sesikhumba somuntu. Njengesilondolozi esisungulwe isikhathi eside nesisetshenziswa kabanzi, i-Methylparaben iphephile ukuthi isetshenziswe ekugxiliseni okucacisiwe futhi isiza ukuvikela imikhiqizo ekungcoleni kwamagciwane. Kulabo abangezwani nesikhumba noma abanezidingo zempilo ezikhethekile, kuwukuhlakanipha ukukhetha imikhiqizo equkethe i-methylparaben ngokucophelela. Ukuqonda imiphumela ethize ye-methylparaben esikhumbeni kungasiza abathengi benze izinqumo ezinolwazi ngohlelo lwabo lokunakekela isikhumba.
