amakuru

Polyvinylpyrrolidone (PVP)， Cas numero 9003-39-8 ， pvp ni polymer itari ionic niyo itandukanye cyane, yizwe neza kandi yize cyane imiti myiza muri N-vinyl amide polymers. Yateye imbere mubyiciro bitari ionic, cationic, anion ibyiciro 3, icyiciro cyinganda, icyiciro cya farumasi, icyiciro cyibiryo cya 3 ibisobanuro, misile ya molekile igereranije kuva ku bihumbi kugeza kuri miliyoni zirenga imwe ya homopolymer, copolymer hamwe n’ibicuruzwa bya polymer bihujwe, kandi hamwe nibintu byihariye bidasanzwe byakoreshejwe henshi.

Imikoreshereze ya PVP ni nini cyane, duhangayikishijwe numutekano wo gukoresha ibicuruzwa, ibikurikira kugirango tuguhe ikiganiro kirambuye kubibazo byinshi duhangayikishijwe cyane.

Polyvinylpyrrolidone yangiza?

Polyvinylpyrrolidone ni uruganda rutari ionic polymer, rukoreshwa cyane cyane mu biyobyabwenge, ibiryo, amavuta yo kwisiga n'ibindi bintu, umutekano ni mwinshi, niba wongeyeho ukurikije amahame abigenga, ukurikije umubare usanzwe ukoreshwa, nyuma yo gukoreshwa ntabwo bizatera ikibazo ku mubiri w'umuntu, nta kibi cyangiza umubiri w'umuntu. Mubihe bisanzwe, polyvinylpyrrolidone ntabwo yangiza umubiri wumuntu iyo wongeyeho ukurikije ibipimo byiyongereyeho, ariko niba birenze ibipimo byumutekano, birashobora kwangiza.

PVPifite inertie nziza ya physiologique, ntabwo yitabira metabolism yabantu, ifite biocompatibilité yo hejuru cyane, kandi mubusanzwe nta kurakara kuruhu rwabantu, amaso hamwe nibibyimba. Kubwibyo, irashobora gukoreshwa nkibikoresho bifata imiti, byangiza kandi bigahurira hamwe murwego rwa farumasi. PVP ubwayo ntigira kanseri, kandi irashobora gukora ibice hamwe nibintu bya polifenol biranga nka tannine. Irashobora gukoreshwa nkibintu bisobanutse hamwe na stabilisateur yinzoga numutobe, no mubijyanye no kwisiga, irashobora kandi gukoreshwa mubicuruzwa byita kuruhu nkizuba ryizuba, bishobora kongera ingaruka zo gutose no gusiga. Igihe cyose bihuye nibipimo byigihugu bijyanye no kongeramo ibicuruzwa bijyanye na PVP, umutekano muke, nta ngaruka mbi z'uburozi zigaragara kumubiri wumuntu.

Polyvinylpyrrolidone irashobora kandi gukoreshwa muri lipstick, eyeshadow, mascara no mubindi byo kwisiga, kugabanya pigment hamwe nibice bimwe na bimwe bigize uburakari bwuruhu nuburozi, kogosha amavuta hamwe na polyethylpyrrolidone bishobora guteza imbere koroshya ubwanwa no gusiga amavuta byiyongera, bikongeramo amabara ya polyethylpyrrolidone. Ongeramo polyvinylpyrrolidone mumiti yinyo irashobora gukumira tartar namabuye.

Ese polyvinylpyrrolidone ifite umutekano kuruhu?

Kuberako PVP ifite uburozi buke cyane nubusembwa bukabije bwa physiologique, nta kurakara kuruhu n'amaso, bifite uburyo bwinshi bwo kwisiga. Uruhare rwa polyvinylpyrrolidone muri mask yo mumaso: kwihutisha kwinjira mubintu, umukozi wo kugumana umusatsi, kugabanya uburakari bwibicuruzwa, umutekano mwiza wibiryo. Polyethylpyrrolidone ifitanye isano nziza nuruhu, ikora firime idahwitse kuruhu rwuruhu, ikina uruhare rwamazi ya emollient, nyuma yo kongeramo polyethylpyrrolidone kuri mask, ibyiyumvo byamavuta bizagabanuka, ubworoherane nubworoherane bizaba byiza, polyethylpyrrolidone irashobora kwihutisha kwinjira mubintu bya mask kandi bikongerera igihe cyo guturamo.

Polyvinylpyrrolidone nibyiza kumisatsi?

Polyvinylpyrrolidone nk'ibikoresho fatizo byo kwisiga, ni ngombwa gukoresha uburyo bwo kugumana imisatsi, ifite ibintu byinshi byiza, ni ibikoresho fatizo byingirakamaro mu gutera imisatsi, amavuta yimisatsi, mousse, polyethylpyrrolidone ifite imiterere myiza ya firime, irashobora gukora firime iboneye, byoroshye gushonga n'amazi, nta kurakara, nta musemburo, nta allergie. Nibikorwa byo gutunganya no gukora firime kubicuruzwa byawe bwite nka mousse na gel gel. Polyvinylpyrrolidone yometse kumisatsi kugirango ikore firime itagaragara, itunganya imisatsi yimisatsi, iramba, ikomeza kumurika kandi idafite umukungugu. Iyo umusatsi udahwitse, urashobora gukwega no kubumba. Iyo bidakoreshejwe, birashobora gukaraba hamwe na shampoo.

Ibyavuzwe haruguru bijyanye no kumenya nibaPVPni umutekano, nizere ko iyi ngingo ishobora kugufasha. Turi abanyamwuga bakora pvp bafite uburambe bwimyaka irenga 10 yuburambe. Niba ufite ikibazo, twandikire.
