iindaba

I-Polyvinylpyrrolidone (PVP), inombolo ye-cas 9003-39-8，pvp yipolymer engeyiyo i-ionic eyeyona yahlukileyo, eyona ifundwe kakhulu kwaye ifundwe ngokubanzi imichiza elungileyo phakathi kweepolima ze-N-vinyl amide. Iphuhliswe yaba ziindidi ezingezizo i-ionic, cationic, anion 3, ibakala leshishini, ibakala loxubo-mayeza, ibakala lokutya le-3, ubunzima bemolekyuli ukusuka kumawaka ukuya ngaphezulu kwesigidi esinye seemveliso ze-homopolymer, i-copolymer kunye ne-crosslinked polymer series, kunye neempawu zayo ezibalaseleyo. isetyenziswe ngokubanzi.

Ukusetyenziswa kwePVP kubanzi kakhulu, sixhalabile malunga nokhuseleko lokusetyenziswa kwemveliso, oku kulandelayo ukukunika intetho ecacileyo malunga nemiba emininzi esiyixhalabele kakhulu.

Ngaba i-polyvinylpyrrolidone iyingozi?

I-Polyvinylpyrrolidone yi-polymer compound engekho i-ionic, esetyenziswa kakhulu kwiziyobisi, ukutya, izimonyo kunye nezinye izinto, ukhuseleko luphezulu kakhulu, ukuba ludibaniswe ngokuhambelana nemigangatho efanelekileyo, ngokwexabiso eliqhelekileyo lokusetyenziswa, emva kokusetyenziswa akuyi kubangela. ukungonwabi kumzimba womntu, akukho bungozi kumzimba womntu. Kwiimeko eziqhelekileyo, i-polyvinylpyrrolidone ayinabungozi kumzimba womntu ukuba yongezwa ngokuhambelana nemigangatho yokongeza echaphazelekayo, kodwa ukuba idlula umgangatho wokhuseleko, ingaba yingozi.

I-PVPine-inertia ebalaseleyo ye-physiological, ayithathi nxaxheba kwimetabolism yabantu, inokuhambelana ne-biocompatibility ephezulu, kwaye ngokusisiseko ayinakucaphuka eluswini lomntu, amehlo kunye nenwebu. Ngoko ke, inokuthi isetyenziswe njenge-adhesive, i-agent ye-detoxification kunye ne-co-solvent kwintsimi yamachiza. I-PVP ngokwayo ayinayo i-carcinogenicity, kwaye inokwenza ii-complexes ezinempawu ze-polyphenol compounds ezifana ne-tannins. Ingasetyenziselwa njenge-ejenti yokucacisa kunye ne-stabilizer yebhiya kunye nejusi, kwaye kwintsimi yezimonyo, ingasetyenziselwa kwiimveliso zokunakekelwa kwesikhumba ezifana ne-sunscreen, enokuphucula umphumo wokumanzisa kunye ne-lubrication. Logama nje ngokuhambelana nemigangatho yesizwe echaphazelekayo ukongeza iimveliso ezinxulumene ne-PVP, ukhuseleko oluphezulu, akukho miphumo ecacileyo yetyhefu emzimbeni womntu.

I-Polyvinylpyrrolidone inokusetyenziselwa i-lipstick, i-eyeshadow, i-mascara kunye nolunye ukuguqulwa kwezinto zokuthambisa, ukunciphisa i-pigment kunye nezinye izinto zokucaphuka kwesikhumba kunye netyhefu, i-cream yokucheba nge-polyethylpyrrolidone inokukhuthaza ukuthambisa iindevu kunye nokunyuka komsebenzi wokuthambisa, ukongeza i-polyethylpyrrolidone kwiimveliso zemibala yeenwele inokulungelelanisa. umbala, ukuphucula ukuqina kombala. Ukongeza i-polyvinylpyrrolidone kwi-toothpaste formulations inokuthintela i-tartar kunye nokwakheka kwamatye.

Ngaba i-polyvinylpyrrolidone ikhuselekile eluswini?

Ngenxa yokuba i-PVP inetyhefu ephantsi kakhulu kunye ne-inertia ephezulu ye-physiological, akukho ukucaphuka kwesikhumba kunye namehlo, inoluhlu olubanzi lwezicelo kwi-cosmetics. Indima ye-polyvinylpyrrolidone kwimaski yobuso: ukukhawuleza ukungena kwezithako, i-agent yokugcinwa kweenwele, ukunciphisa ukucaphuka kwemveliso, ukhuseleko lokutya okulungileyo. I-Polyethylpyrrolidone inobudlelwane obuhle bolusu, yenza ifilimu engabonakaliyo ebusweni besikhumba, idlala indima yokuthambisa i-emollient, emva kokongeza i-polyethylpyrrolidone kwimaski, imvakalelo yeoli iya kuncitshiswa, ukuthamba kunye nokugudiswa kuya kuba ngcono, i-polyethylpyrrolidone. inokukhawulezisa ukungena kwezithako zemaski kunye nokwandisa ixesha lokuhlala lezithako.

Ngaba i-polyvinylpyrrolidone ilungile kwizinwele?

I-Polyvinylpyrrolidone njengento eluhlaza yezinto zokuthambisa, kubalulekile ukuba isetyenziswe kwi-arhente yokugcina isitayile seenwele, ineempawu ezininzi ezigqwesileyo, iyimathiriyeli eyimfuneko yokutshiza iinwele, ikhrimu yeenwele, i-mousse, i-polyethylpyrrolidone ineempawu ezilungileyo zokwenza ifilimu, inokwenza into ecacileyo. ifilimu, inobudlelwane obuhle, kulula ukuyinyibilika ngamanzi, ayinakucaphuka, ayinakwalana, kwaye inefuthe elihle lokukhusela iinwele. Yiarhente yesimbo kunye ne-ejenti yokwenza ifilimu kwiimveliso zokhathalelo lomntu ezifana ne-mousse kunye nejeli yeenwele. I-Polyvinylpyrrolidone ifakwe kwizinwele ukuze zenze ifilimu engabonakaliyo, ilungisa isitayela seenwele, iyenze ibe yinto ehlala ixesha elide, igcine igqamile kwaye ingenathuli. Xa iinwele zimdaka, zinokukanywa kwaye zibunjwe kwakhona. Xa ingasetyenziswa, inokuhlanjwa ngeshampu.

Oku kungasentla kumalunga nokubaI-PVPikhuselekile, ndiyathemba ukuba eli nqaku linokukunceda. Singumenzi we-pvp oqeqeshiweyo oneminyaka engaphezu kwe-10 yamava emveliso. Ukuba unayo nayiphi na imibuzo, nceda uqhagamshelane nathi.
