IISEBE:UMethylpairan ngumzekelo we-methyl utywala kunye ne-h-hydroxybic acid, i-arhente ye-bactetiostatic kwaye ikhulisa i-vactericic ngaphambi kokuvezwa kwe-Arhente ye-Arhente Iveliswa ngeendlela ezifanayo zemveliso, njenge-EthydroXREXYEBLOZUX (I-Paraben B) kunye ne-Propyl P-HydroxyByenzote (Nepalese c), nayo i-projecvatives. Imveliso iyacaphukisa ulusu. Iparabens yenye yeqela eliqhelekileyo elisetyenzisiweyo lezinto ezisetyenziswayo kwi-cosmetic, amayeza, kunye namashishini okutya. I-parabens ibonelela ngomsebenzi we-bactetiostatic kunye ne-fungstistatic ngokuchasene nenani lezinto eziphilayo, kwaye zithathwa njengekhuselekileyo ukuze zisetyenziswe kwi-cosmetics, ngakumbi ekukhanyeni kwamandla abo aphantsi. Uvavanyo lwezilondolozo ukuze lusetyenziswe kwikhefu-kwizicwangciso ze-cosmetic zidwelisa iparabens phakathi kweenzuzo ezincinci. Uluhlu lweengcinezelo ezisetyenzisiweyo kwizikona ziyahluka phakathi kwe-0.03 kunye ne-0.30 pesenti yongezwa kuyo. Ngokwethala leencwadi likazwelonke lamayeza, isithako sivela ngokwemvelo kwisandla esineziqhamo-njengama-bienderries-nangona sinokwenziwa kuyo yonke into ekuhlambulukayo kunye ne-rourizers kwi-prims kwaye inceda ezi mveliso zigcina impumelelo. IRabach ithi-igcwele i-curck-igcwele iipropathi ze-antibacteritial kunye ne-antibacteritive, esebenza imimangaliso yokongeza ubomi beshelufa ye-skefcare, ukhathalelo lweenwele, kunye neemveliso zecosmetic.
UMethylpairabin yiarhente ye-antimicrobial ongumgubo omhlophe wasimahla. Isebenza ngokuchasene negwele kwaye ibumba kakhulu kwinqanaba le-pH. Bona iParabens. I-methyl 4-i-hydroxybenzote isetyenziswa njengearhente ye-anti-fungal. Ikwasetyenziswa njengendawo yokugcina ukutya, i-goby kunye ne-cosmetics. Isebenza njenge-inhibitor yokukhula kwe-molds kunye ne-bacteria encinci kunye nemoto ye-Ophthalmimic.
Intshayelelo Eneenkcukacha
I-methylpairamide yindawo esetyenziswayo isetyenziswa kwishishini lokhathalelo kunye nononophelo lomntu. Lilungu lentsapho yeParaben, equka ezinye izinto ezilondolozo njenge-Elyylparabien, Propylpairan, kunye ne-butylparaen, kunye ne-butylparan.
Ulondolozo: UMethylpairan wongezwa kwi-cosmetics kunye neemveliso zononophelo lomntu ukunqanda ukukhula kunye nokwanda kweentsholongwane ezifana ne-bacteria kunye nefungi. Inceda ukwandisa ubomi beshelfu yezi mveliso kwaye kugcinwe umgangatho wabo kunye nokhuseleko.
Ukhuseleko:UMethylpairaen ufundiwe kakhulu kwaye wathathwa ngokukhuselekileyo ukuze asetyenziswe kwi-cosmetics kunye neemveliso zononophelo zobuqu ngamabhuli enkqubo yokutya kunye neKhomishini yabaThengi (i-SCS), kunye noPhononongo lweChet).
Ukusetyenziswa ngokubanzi:UMethylpairaen unokufumaneka kwiintlobo ezahlukeneyo zemveliso, kubandakanya iikhrim, i-lotions, i-shampoos, oomongameli, i-sumeup, iicoodorants, kunye ne-doorads, kunye nelanga. Isetyenziswa ngokubanzi ngenxa yokusebenza kwayo, ukuzinza kwayo, kunye nokuhambelana neendlela ezininzi zokwenza izinto zokucinga.
Ezinye iiparabens: UMethylpairan uhlala esetyenziswa ngokudibeneyo nezinye iiparabens (njenge-EmyyyParabien, i-Propylpairan, kunye ne-butylparaen) ukubonelela ngesixhobo esibanzi sokukhuselwa ngokubanzi.
Ezona zinto zibalulekileyo:Kwiminyaka yakutshanje, kuye kwakho iimfuno zabathengi ngeendlela ezilondolozayo. Njengempendulo, ezinye iinkampani ze-cosmetic ziqale ukusebenzisa ezinye izinto ezizimeleyo okanye ukukhetha imizobo engenaziphelo. Nangona kunjalo, uMethylpairaine uhlala esebenzisekile ngokubanzi kwaye evunyiweyo kulondolozo.
Kubalulekile ukuba uqaphele ukuba ngelixa i-methylpairamien ifundile kakhulu kwaye ibonwa ngokukhuselekileyo ukuze isetyenziswe, abanye abantu banokufumana iimvakalelo okanye baphembelele kwisinye isithako. Ukuba unezinto ezixhalabisayo okanye imibuzo ethile malunga nezithako ze-cosmetic, kungcono ukunxibelelana ne-dermatologist okanye ingcali yezempilo.
Isicelo
UMethylpairan ngokuyintloko asetyenziswa njengelungelo lokhathalelo lononophelo lobuqu, cosmetic, neemveliso zamayeza. Eyona njongo yayo kukuthintela ukukhula kweentsholongwane, igwele, kunye nokubumba, ngaloo ndlela wadlulisela ubomi beshesi kunye nokuqinisekisa ukhuseleko lwezi mveliso. Nazi ezinye iinkqubo eziqhelekileyo ze-methylpairabin:
Iimveliso ze-Skercare:UMethylpairamin unokufumaneka kumagwebulo, amahlathi, imaski yobuso, iitoni, kunye nezinye iimveliso zolusu ukuze zigcine umgangatho wazo kunye nokuthintela ungcoliseko lwentsholongwane.
Iimveliso zokugcina iinwele:UMethylpairaen usetyenziswa kwi-shampoos, oomongameli, imaski yeenwele, kunye neemveliso zokuzibhabha ukugcina ifomula yazo kwaye kuthintele ukukhula kweentsholongwane.
Iimveliso zononophelo lomzimba:UMethylpairaen uhlala esongezwa kwi-outs emzimbeni, ukuhlamba umzimba, i-doodrads, kunye nezinye izinto zononophelo zokuthintela ukonakala kwaye zigcine uzinzo lwemveliso.
Iimveliso zokwenza:UMethylpairaen uhlala esetyenziswa kwiintlobo ngeentlobo zezinto eziphakamileyo, kubandakanya iziseko, iipowders, zamehlo, i-furshes, kunye neelekti, ukunqanda ukukhula kweentsholongwane kunye nefungi.
Iimveliso zamachiza:UMethylpairamin unokukhona kuminyeliso lomlomo, ii-crims, i-oyile, kunye nezinye iindlela zamayeza njengezilondolozo zokuqinisekisa ukhuseleko lwabo kwaye zikhusele ungcoliseko.
Kubalulekile ukuba uqaphele ukuba ukusetyenziswa kwe-methylpairamie kwimveliso kulawulwa ngabasemagunyeni njenge-FDA (eUnited States) kunye nekhomishini yaseYurophu kwi-EU. Ezi arhente zisetwa imida yoxinaniso ekusetyenzisweni kwe-methylparabirn kunye nezinye izinto zokugcina ukuqinisekisa ukhuseleko lwemveliso.
