I-Polyvinylpyrrolidone (PVP)Inombolo ye-cas 9003-39-8, i-pvp yi-polymer engeyiyo i-ionic eyikhemikhali egqwesileyo, efundwe kakhulu kwaye ifundwe kakhulu phakathi kwee-polymers ze-N-vinyl amide. Iphuhliswe yaba ziindidi ezingezizo i-ionic, i-cationic, i-anion 3, i-industrial grade, i-pharmaceutical grade, i-food grade 3 specifications, ubunzima beemolekyuli ukusuka kumawaka ukuya kwi-homopolymer engaphezulu kwesigidi, i-copolymer kunye neemveliso ze-polymer ezidibeneyo, kwaye ngeempawu zayo ezikhethekileyo ezibalaseleyo zisetyenziswe kakhulu.

Ukusetyenziswa kwe-PVP kubanzi kakhulu, sixhalabile malunga nokhuseleko lokusetyenziswa kwemveliso, oku kulandelayo kukunika intetho eneenkcukacha malunga nemiba eliqela esixhalabele ngakumbi.

Ngaba i-polyvinylpyrrolidone iyingozi?

I-Polyvinylpyrrolidone yi-polymer compound engeyiyo i-ionic, esetyenziswa kakhulu kwiziyobisi, ukutya, izinto zokuthambisa kunye nezinye izinto, ukhuseleko luphezulu kakhulu, ukuba yongezwa ngokuhambelana nemigangatho efanelekileyo, ngokwesixa esiqhelekileyo sokusetyenziswa, emva kokusetyenziswa ayiyi kubangela ukungonwabi emzimbeni womntu, akukho monakalo emzimbeni womntu. Kwiimeko eziqhelekileyo, i-polyvinylpyrrolidone ayinabungozi emzimbeni womntu ukuba yongezwa ngokuhambelana nemigangatho efanelekileyo yokongeza, kodwa ukuba idlula umgangatho wokhuseleko, inokuba yingozi.

I-PVPIne-inertia entle kakhulu ye-physiological, ayithathi nxaxheba kwi-metabolism yomntu, ihambelana kakhulu ne-biocompatibility, kwaye ngokusisiseko ayinakurhawuzelelwa lusu lomntu, amehlo kunye ne-mucous membranes. Ke ngoko, ingasetyenziswa njenge-glue, i-detoxification agent kunye ne-co-solvent kwicandelo lezemithi. I-PVP ngokwayo ayinayo i-carcinogenicity, kwaye inokwenza ii-complexes ezinee-polyphenol compounds ezifana ne-tannins. Ingasetyenziswa njenge-clearing agent kunye ne-stabilizer yebhiya kunye nejusi, kwaye kwicandelo lezinto zokuthambisa, ingasetyenziswa nakwiimveliso zokhathalelo lolusu ezifana ne-sunscreen, enokuphucula isiphumo sokumanzisa kunye nokuthambisa. Ukuba nje ihambelana nemigangatho yesizwe efanelekileyo yokongeza iimveliso ezinxulumene ne-PVP, ukhuseleko oluphezulu, akukho miphumo inobungozi ebonakalayo emzimbeni womntu.

I-Polyvinylpyrrolidone ingasetyenziswa nakwi-lipstick, i-eyeshadow, i-mascara kunye nezinye iindlela zokulungisa ubuhle, ukunciphisa umbala kunye nezinye izinto ezibangela ukurhawuzelelwa kwesikhumba kunye nobuthi, i-cream yokucheba ene-polyethylpyrrolidone inokukhuthaza ukuthamba kweendevu kunye nokunyusa umsebenzi wokuthambisa, ukongeza i-polyethylpyrrolidone kwiimveliso zombala weenwele kunokulungisa umbala, kuphucule ukuqina kombala. Ukongeza i-polyvinylpyrrolidone kwi-toothpaste formulations kunokuthintela ukwakheka kwe-tartar kunye namatye.

Ngaba i-polyvinylpyrrolidone ikhuselekile kulusu?

Ngenxa yokuba i-PVP inetyhefu encinci kakhulu kwaye ayinayo i-inertia ephezulu yomzimba, ayinakurhawuzelelwa lusu namehlo, inoluhlu olubanzi lwezicelo kwizithambiso. Indima ye-polyvinylpyrrolidone kwimaski yobuso: ukukhawulezisa ukungena kwezithako, iarhente yokugcina iinwele, ukunciphisa ukurhawuzelelwa kwemveliso, ukhuseleko lokutya oluhle. I-Polyethylpyrrolidone inobuhlobo obuhle nolusu, yenza ifilimu engagqumiyo kumphezulu wolusu, idlala indima yokufumisa njenge-emollient, emva kokongeza i-polyethylpyrrolidone kwimaski, uvakalelo lweoyile luya kuncipha, ukuthamba kunye noburhabaxa kuya kuba ngcono, i-polyethylpyrrolidone inokukhawulezisa ukungena kwezithako zemaski kwaye yandise ixesha lokuhlala kwezithako.

Ngaba i-polyvinylpyrrolidone ilungile kwiinwele?

I-Polyvinylpyrrolidone njengesixhobo sokwenziwa kwezinto zokuthambisa, kubalulekile ukuyisebenzisa njengesixhobo sokugcina iinwele, ineempawu ezininzi ezintle, sisixhobo esibalulekileyo sokutshiza iinwele, ikhrimu yeenwele, i-mousse, i-polyethylpyrrolidone ineempawu ezintle zokwenza ulwelo, inokwenza ifilimu ecacileyo, inobuhlobo obuhle, kulula ukuyinyibilikisa ngamanzi, ayinakurhawuzelelwa, ayina-allergy, kwaye inefuthe elihle lokukhusela iinwele. Yiarhente yokwenza isitayile kunye nearhente yokwenza ulwelo kwiimveliso zokhathalelo lomntu ezifana ne-mousse kunye nejeli yeenwele. I-Polyvinylpyrrolidone incamatheliswe ezinweleni ukwenza ifilimu engabonakaliyo, ilungisa isitayela seenwele, izenze zihlale ixesha elide, zihlale zikhazimla kwaye zingabi nothuli. Xa iinwele zingacocekanga, zinokukamshwa kwaye zibunjwe kwakhona. Xa zingasetyenziswa, zingahlanjwa ngeshampu.

Oku kungasentla malunga nokubaI-PVPikhuselekile, ndiyathemba ukuba eli nqaku linokukunceda. Singumvelisi we-pvp oqeqeshiweyo onamava angaphezu kweminyaka eli-10 kwimveliso. Ukuba unemibuzo, nceda unxibelelane nathi.
