Maphunziro a Mankhwala:Zogwiritsa Ntchito Zina -> Zoteteza
Kumwetulira kwa Canonan:Coc (= o) c1 = cc = c (c = c1) o
Gwiritsani Ntchito:Methylparn ndi ester ya methyl mowa ndi p-hydroxybente rockisic isanayambitsidwe Njira, monga ethyl p-hydroxybenzoate (paraben b) ndi propyl p-hydroxybentenzoate (Nepalese c), amakhumudwitsa pakhungu. Parabeti ndi amodzi mwa gulu logwiritsidwa ntchito posungiramo zodzikongoletsera, mankhwala opangira mankhwala, ndi mafakitale. Parabeti amapereka bacteriostatic ndi fungistic ntchito yolimbana ndi kuchuluka kwa zinthu zosiyanasiyana, ndipo amadziwika kuti amagwiritsidwa ntchito popanga zodzola, makamaka popepuka. Kufufuza kwa oteteza zogwiritsa ntchito pokonzekera kungoletsa ma cosmetic kumayambira parabeni pakati pa chidwi chochepa. Mitundu yokhazikika yomwe imagwiritsidwa ntchito mosiyanasiyana pakati pa 0,03 ndi 0,30 peresenti, kutengera momwe paraben amagwiritsira ntchito ndi imodzi mwazinthu zodziwika bwino kwambiri ndi zinthu zodziwika bwino. Malinga ndi laibulale yadziko la mankhwala, zosakaniza zimachitika mwachilengedwe zipatso zambiri monga mabulosi owoneka bwino. Rapianani akuti ndizachiritso-fungal ndi antibacterial katundu, zomwe zimagwira ntchito zozizwitsa kuti titalimize moyo wa skiincare, kumeta, komanso zodzikongoletsera.
Methylparn ndi antimicrobial wothandizira yemwe ndi ufa woyera. Imagwira ntchito yolimbana ndi yisiti ndikupanga nkhungu kuposa mankhunje. Onani parabeni. Methyl 4-hydroxybentenzoate imagwiritsidwa ntchito ngati wotsutsa-fungal wothandizira. Amagwiritsidwanso ntchito ngati chosungira zakudya, zakumwa zonyamula zakumwa. Imagwira ngati cholepheretsa kukula kwa nkhungu ndi pang'ono pang'ono mabakiteriya komanso ngati galimoto ya ophthalmic yankho.
Mawu owonjezera
Methylparn ndi chosungira chogwiritsidwa ntchito muzodzikongoletsera zodzikongoletsera zaumwini komanso zamunthu. Ndilo membala wa banja la paraben, lomwe limaphatikizapo ena osungirako ethylparn, propylparn, ndi mbylparn.
Kutetezedwa: Methylparn imawonjezeredwa ku zodzoladzola komanso zinthu zosamalira payekha kuti mupewe kukula ndi kuchuluka kwa tizilombo tating'onoting'ono monga mabakiteriya ndi bowa. Zimathandizira kukulitsa moyo wa alumali wa zinthuzi ndikusunga chitetezo komanso chitetezo.
Chitetezo:Methylpararn yaphunziridwa kwambiri ndikukhala otetezeka kuti mugwiritse ntchito zodzikongoletsera ndi zopangidwa ndi anthu omwe ali ndi vuto la anthu asayansi.
Kugwiritsa ntchito kwakukulu:Methylparn imatha kupezeka pazogulitsa zosiyanasiyana, kuphatikizare zozitiza, zodzola, shampoos, zowongolera, zodzoladzola, ndi ma deodons. Imagwiritsidwa ntchito kwambiri chifukwa cha kugwira kwake, kukhazikika, komanso kuphatikizidwa ndi mapangidwe ambiri odzikongoletsera.
Parbens ena: Methylparn nthawi zambiri imagwiritsidwa ntchito limodzi ndi parbens (monga ethylparn, propylparn, ndi mbylparn) kuti ithandizire chitetezo cha antimicrobiali.
Zoteteza Zina:M'zaka zaposachedwa, pamakhala ogula ogula kwa njira zina zokopa. Monga yankho, makampani ena odzikongoletsera ayamba kugwiritsa ntchito njira zina kapena kusamalira njira zopanda chitetezo. Komabe, methylpararn imagwiritsidwa ntchitobe ntchito kwambiri komanso kuvomerezedwa mu malonda.
Ndikofunikira kudziwa kuti ngakhale methylpargen yaphunziridwa kwambiri ndipo ikuwoneka bwino kuti igwiritsidwe ntchito, anthu ena amatha kuvomerezedwa kapena matupi awo sagwirizana, monganso mankhwala ena aliwonse. Ngati muli ndi nkhawa kapena mafunso ena okhudzana ndi zodzikongoletsera, ndibwino kukambirana ndi dermato wadokotala kapena akatswiri azaumoyo.
Karata yanchito
Methylparn imagwiritsidwa ntchito ngati yosungirako zinthu zosiyanasiyana, zodzikongoletsera, ndi mankhwala opangira mankhwala. Cholinga chake ndikuletsa kukula kwa mabakiteriya, yisiti, ndi nkhungu, potero kufalitsa moyo wa alumali ndikuonetsetsa kuti chitetezo chazomwezo. Nazi ntchito zingapo za methylparphern:
Skincare malonda:Methylparn imatha kupezeka mu yonyowa, oyeretsa, nkhope masks, ovomerezeka, ndi zinthu zina zogulitsa kuti zizikhala bwino komanso kupewa microb.
Zogulitsa:Methylpararn imagwiritsidwa ntchito mu shampoos, zowongolera, masks a tsitsi, zopangidwa ndi ma styling kuti asunge njira zawo ndikulepheretsa kukula kwa tizilombo tating'onoting'ono.
Zogulitsa za Thupi:Methylparn imawonjezeredwa ndi zotupa zodzolale za thupi, zimaswa thupi, ma deodorants, ndi zinthu zina zosamalira payekha kuti zisakhale ndi bala.
Zogulitsa:Methylparn imagwiritsidwa ntchito mwanjira zosiyanasiyana zodzola zosiyanasiyana, kuphatikiza maziko, mawonekedwe, matumbo, ndi milomo, kupewa kukula kwa mabakiteriya ndi bowa.
Zogulitsa za mankhwala:Methylparn imatha kukhalapo m'malo oyimilira pakamwa, mafuta, mafuta ena, ndi zina zopangira mankhwala monga chosungira kuti atetezedwe ndi kupewa kuipitsidwa.
Ndikofunikira kudziwa kuti kugwiritsa ntchito methylparone mu zinthu kumayendetsedwa ndi olamulira ngati FDA (ku United States) ndi European Commission in EU. Mabungwe awa amakhazikitsa malire ogwiritsira ntchito methylparvan ndi ena osungirako ena kuti atsimikizire chitetezo chambiri.
