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 yi-non-ionic, i-cationic, i-anion 3 iindidi, ibakala lemizi-mveliso, 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 iimveliso, kunye neempawu zayo ezibalaseleyo zisetyenziswe 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, izithambiso kunye nezinye izinto, ukhuseleko luphezulu kakhulu, ukuba ludityaniswe ngokuhambelana nemigangatho efanelekileyo, ngokomlinganiselo oqhelekileyo wokusetyenziswa, emva kokusetyenziswa akuyi kubangela ukuphazamiseka kumzimba womntu, akukho monakalo 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 inokusetyenziswa kwi-lipstick, i-eyeshadow, i-mascara kunye nolunye ukuguqulwa kwezinto zokuthambisa, ukunciphisa i-pigment kunye nezinye izinto zokucaphuka kwesikhumba kunye netyhefu, ukucheba ukhilimu nge-polyethylpyrrolidone kunokukhuthaza ukuthambisa iindevu kunye nokunyuka komsebenzi wokuthambisa, ukongeza i-polyethylpyrrolidone kwibala leenwele, ukuphucula umbala wemveliso yeenwele. 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 engathinteliyo kumphezulu wolusu, idlala indima yokuthambisa ye-emollient, emva kokongeza i-polyethylpyrrolidone kwimaski, imvakalelo yeoli iya kuncitshiswa, ukuthamba kunye nokuguda kuya kuba ngcono, i-polyethylpyrrolidone inokukhawulezisa ukunyusa ixesha le-mask yezithako kunye nokukhawuleza kwe-mask.

Ngaba i-polyvinylpyrrolidone ilungile kwizinwele?

I-Polyvinylpyrrolidone njengento ekrwada yezinto zokuthambisa, kubalulekile ukuyisebenzisela ukugcinwa kwesitayile seenwele, ineempawu ezininzi ezigqwesileyo, iyimathiriyeli eyimfuneko yokutshiza iinwele, ikhrimu yeenwele, i-mousse, i-polyethylpyrrolidone ineempawu ezintle zokwenza ifilimu, inokwenza ifilimu esobala, inobudlelwane obuhle, kulula ukuyinyibilika, ayinakunyibilika kwaye ayinayo impembelelo entle kumanzi, ayinakunyibilika kwaye ayinakudityaniswa namanzi. 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, yenza ukuba ihlale iqinile, igcine iqaqambileyo 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.
