Impembelelo yeMethylparaben kwesikhumba: uhlalutyo olubanzi
I-Methylparaben, ekwabizwa ngokuba yi-methylparaben, sisilondolozi esisetyenziswa kakhulu kwizithambiso, ukutya kunye namayeza. Kuye kwaba yinto ebalulekileyo kwiimveliso ezininzi ngenxa yezinto ezisebenzayo zokulwa ne-antimicrobial, kodwa oku kuye kwakhokelela kwingxoxo ebanzi kunye nophando malunga nemiphumo yalo eluswini. Kweli phepha, siya kuhlalutya ngokweenkcukacha iziphumo ezithile ze-methyl hydroxyphenyl ester esikhumbeni kwaye sixoxe ngokusetyenziswa kwayo kwishishini le-cosmetic.
Iimpawu zeMichiza kunye nezicelo zeMethylparaben
I-Methyl hydroxyphenyl ester yi-methyl ester ye-p-hydroxybenzoic acid, enye yezona zinto zisetyenziswa ngokuqhelekileyo kwi-paraben preservatives. Umsebenzi wayo oyintloko kukwandisa ubomi beshelufu yeemveliso ngokuthintela ukukhula kweebhaktheriya, igwele kunye nokubumba. Ngenxa yeendleko eziphantsi kunye nokusebenza kakuhle, i-methylparaben yongezwa ngokubanzi kwiimveliso zokunakekelwa kwesikhumba, i-shampoos, i-lotions kunye nezinye iimveliso zokunakekelwa kwemihla ngemihla.
Iziphumo ezilungileyo zeMethylparaben kwiLusu
Isenzo se-Methylparaben sokukhusela sithintela ukungcoliseka kwe-microbial kwiimveliso zokuthambisa, ngaloo ndlela kunciphisa umngcipheko wosulelo olunokwenzeka eluswini. Iimveliso ezingangcoliswanga zibonelela ngamava akhuselekileyo esikhumbeni, ngakumbi kubantu abanesikhumba esibucayi, kunye nokusetyenziswa kwemveliso yokugcinwa kwezilwanyana kunokunceda ukuphepha iingxaki zesikhumba ezibangelwa yibhaktheriya okanye isikhunta.
Ngenxa yoxinaniso oluphantsi lweMethylparaben esetyenzisiweyo (ngokuqhelekileyo ingaphantsi kwe-1%), ayinayo impembelelo embi kakhulu eluswini lwabantu abaninzi. Izifundo ezininzi zibonise ukuba i-methylparaben ilusu oluphantsi olucaphukisayo ekugxininiseni ukusetyenziswa okumiselweyo kwaye ayibangeli ukuvuselela ulusu okanye ezinye iimpendulo ezibukhali. Ngoko ke, njengesiqhelo kunye nokugcinwa okuqinisekisiweyo ngokubanzi, i-methylparaben ibonelela ngeqondo lokhuseleko lwemveliso.
Imiphumo emibi enokubakho ye-methylparaben eluswini
Nangona iMethylparaben ikhuselekile kuninzi lwabemi kwindawo ephantsi, kusekho izifundo kunye neengxelo ezicebisa ukuba inokuba neziphumo ezibi eluswini. Ukusetyenziswa ixesha elide kweemveliso eziqulethe i-methylparaben inokuchaphazela umsebenzi wokuthintela ulusu, ngakumbi kubantu abanolusu olubuthathaka okanye esele lonakele.
I-Methylparaben nayo ityholwa ngokuba nomsebenzi obuthathaka we-estrogenic, kwaye nangona oku kungakhange kuboniswe ngokucacileyo ukuba yingozi ngqo kwimpilo yabantu phantsi kokusetyenziswa okuqhelekileyo, ezinye iingcali zesikhumba zincoma ukuba abafazi abakhulelweyo kunye nabantu abasengozini enkulu yomhlaza webele kufuneka bazame ukuphepha ukusetyenziswa kwexesha elide leemveliso eziqukethe i-methylparaben.
Uzisebenzisa njani iimveliso ezine-methylparaben ngokukhuselekileyo
Ukuqinisekisa impilo kunye nokhuseleko lolusu, abathengi kufuneka banikele ingqalelo kula manqaku alandelayo xa bekhetha iimveliso ezine-methylparaben: Khetha iibrendi ezinkulu okanye iimveliso ezithembekileyo, njengoko ezi mveliso zihlala zinolawulo olungqongqo lwezithako kunye nophando lokuqulunqa. Nika ingqalelo kwimiyalelo yokusetyenziswa kweemveliso ukuphepha ukugqithisa okanye ukusetyenziswa rhoqo. Abantu abanolusu olubuthathaka kufuneka bathathele ingqalelo ezinye iimveliso ezikhuselayo ezinomngcipheko ophantsi wokungalungelani, okanye bakhethe iimveliso zokhathalelo lwesikhumba ezibhalwe “njengezigcinayo” okanye “ezigcinwe ngokwendalo”.
Ukuqukumbela
Impembelelo ye-methylparaben eluswini ixhomekeke kakhulu ekugxininiseni okusetyenzisiweyo kunye nemeko yesikhumba somntu. Njengesilondolozi esele simiselwe ixesha elide kwaye sisetyenziswa ngokubanzi, iMethylparaben ikhuselekile ukuba isetyenziswe kwiindawo ezichaziweyo kwaye inceda ukukhusela iimveliso kungcoliseko lwemicrobial. Kwabo banobuthathaka bolusu okanye abaneemfuno zempilo ezikhethekileyo, kububulumko ukukhetha iimveliso ezine-methylparaben ngononophelo. Ukuqonda iziphumo ezithile ze-methylparaben eluswini kunokunceda abathengi benze ukhetho olunolwazi ngakumbi kwindlela yokunyamekela ulusu.
