nkhani

Polyvinylpyrrolidone (PVP), cas number 9003-39-8, pvp ndi polima osakhala aionic omwe ndi apadera kwambiri, ophunziridwa bwino kwambiri komanso odziwika bwino kwambiri pakati pa ma polima a N-vinyl amide. Zakhala magulu a non-ionic, cationic, anion 3, kalasi ya mafakitale, kalasi yamankhwala, zakudya za giredi 3, kuchuluka kwa maselo kuchokera pa masauzande kupita ku mahomopolymer oposa miliyoni imodzi, copolymer ndi crosslinked polymer series products, ndipo ndi katundu wake wapadera kwambiri. akhala akugwiritsidwa ntchito kwambiri.

Kugwiritsiridwa ntchito kwa PVP ndikwambiri, tikukhudzidwa ndi chitetezo chogwiritsira ntchito mankhwala, zotsatirazi kuti tikupatseni tsatanetsatane wa nkhani zingapo zomwe timadera nkhawa kwambiri.

Kodi polyvinylpyrrolidone ndi yowopsa?

Polyvinylpyrrolidone ndi sanali ionic polima pawiri, makamaka ntchito mankhwala, chakudya, zodzoladzola ndi zinthu zina, chitetezo ndi ndi mkulu, ngati anawonjezera malinga ndi mfundo zogwirizana, malinga ndi kuchuluka kwa ntchito, pambuyo ntchito sikudzayambitsa. kusapeza bwino kwa thupi la munthu, palibe vuto lililonse m'thupi la munthu. Munthawi yanthawi zonse, polyvinylpyrrolidone siivulaza thupi la munthu ngati ionjezedwa molingana ndi mfundo zowonjezera, koma ngati ipitilira muyezo wachitetezo, zitha kukhala zovulaza.

Mtengo PVPali ndi inertia yabwino kwambiri ya thupi, satenga nawo mbali mu metabolism yaumunthu, ali ndi biocompatibility yapamwamba, ndipo kwenikweni alibe mkwiyo pakhungu, maso ndi mucous nembanemba. Choncho, angagwiritsidwe ntchito ngati zomatira, detoxification wothandizira ndi co-solvent m'munda mankhwala. PVP yokha ilibe carcinogenicity, ndipo imatha kupanga ma complexes okhala ndi mawonekedwe a polyphenol monga ma tannins. Itha kugwiritsidwa ntchito ngati chowunikira komanso chokhazikika chamowa ndi madzi, komanso m'munda wa zodzoladzola, itha kugwiritsidwanso ntchito pazinthu zosamalira khungu monga zoteteza ku dzuwa, zomwe zimatha kukulitsa mphamvu ya kunyowetsa ndi mafuta. Malingana ngati zikugwirizana ndi zofunikira za dziko kuti muwonjezere mankhwala okhudzana ndi PVP, chitetezo chachikulu, palibe zotsatira zoonekeratu za poizoni pa thupi la munthu.

Polyvinylpyrrolidone Angagwiritsidwenso ntchito milomo, eyeshadow, mascara ndi zodzoladzola kusinthidwa zina, kuchepetsa pigment ndi zigawo zina za khungu kuyabwa ndi kawopsedwe, kumeta kirimu ndi polyethylpyrrolidone akhoza kulimbikitsa ndevu softening ndi kondomu ntchito kuwonjezeka, kuwonjezera polyethylpyrrolidone mu mankhwala tsitsi akhoza kusintha tsitsi. mtundu, kusintha kulimba kwa mtundu. Kuonjezera polyvinylpyrrolidone ku mankhwala otsukira mano kungalepheretse kupanga tartar ndi miyala.

Kodi polyvinylpyrrolidone ndi yotetezeka pakhungu?

Chifukwa PVP ili ndi kawopsedwe kakang'ono kwambiri komanso inertia yayikulu yakuthupi, osakwiya pakhungu ndi maso, imakhala ndi zodzoladzola zosiyanasiyana. Udindo wa polyvinylpyrrolidone mu chigoba cha nkhope: kufulumizitsa malowedwe a zosakaniza, wothandizira tsitsi posungira, kuchepetsa kukwiya kwa mankhwala, chitetezo chabwino cha chakudya. Polyethylpyrrolidone ili ndi kuyanjana kwabwino kwa khungu, imapanga filimu yosagwirizana ndi khungu, imagwira ntchito yochepetsetsa ya emollient, itatha kuwonjezera polyethylpyrrolidone ku chigoba, kumverera kwa mafuta kudzachepetsedwa, kufewa ndi kusalala kudzakhala bwino, polyethylpyrrolidone. ikhoza kufulumizitsa kulowa kwa zosakaniza za chigoba ndikuwonjezera nthawi yokhalamo zosakaniza.

Kodi polyvinylpyrrolidone ndi yabwino kwa tsitsi?

Polyvinylpyrrolidone ngati zopangira zodzoladzola, ndizofunika kuti zigwiritsidwe ntchito posungira tsitsi kalembedwe, zimakhala ndi zinthu zambiri zabwino kwambiri, ndizofunikira kwambiri zopangira tsitsi, kirimu, mousse, polyethylpyrrolidone ili ndi mawonekedwe abwino opanga mafilimu, imatha kupanga mawonekedwe owonekera. filimuyo, ili ndi chiyanjano chabwino, yosavuta kusungunuka ndi madzi, palibe kupsa mtima, palibe ziwengo, ndipo imakhala ndi chitetezo chabwino pa tsitsi. Ndiwopanga makongoletsedwe komanso opanga mafilimu pazinthu zosamalira anthu monga mousse ndi gel osakaniza tsitsi. Polyvinylpyrrolidone imamangiriridwa ku tsitsi kuti apange filimu yosaoneka, kukonza kalembedwe ka tsitsi, kamene kamakhala kolimba, kokhala kowala komanso kopanda fumbi. Tsitsi likadavunda, limatha kulipesekera ndi kuumbidwanso. Ikapanda kugwiritsidwa ntchito, imatha kutsukidwa ndi shampoo.

Zomwe zili pamwambazi ndizokhudza ngatiMtengo PVPndi otetezeka, ndikukhulupirira kuti nkhaniyi ingakuthandizeni. Ndife akatswiri opanga pvp omwe ali ndi zaka zopitilira 10 zopanga. Ngati muli ndi mafunso, chonde titumizireni.
