izindaba

I-Polyvinylpyrrolidone (PVP), inombolo ye-cas 9003-39-8, i-pvp iyi-polymer engeyona i-ionic eyikhemikhali enhle ehluke kakhulu, efundwe kahle kakhulu futhi efundwe kabanzi phakathi kwama-N-vinyl amide polymers.Ithuthuke yaba izigaba ezingezona i-ionic, i-cationic, i-anion 3, ibanga lezimboni, ibanga lezemithi, imininingwane yebanga lesi-3, isisindo samangqamuzana esihlobene ukusuka ezinkulungwaneni kuye kwangaphezu kwesigidi se-homopolymer, i-copolymer kanye nemikhiqizo yochungechunge lwe-polymer ehlanganisiwe, futhi ngezakhiwo zayo ezinhle kakhulu ezihlukile isetshenziswe kabanzi.

Ukusetshenziswa kwe-PVP kubanzi kakhulu, sikhathazekile ngokuphepha kokusetshenziswa komkhiqizo, okulandelayo ukuze sikunikeze inkulumo enemininingwane mayelana nezindaba ezimbalwa esikhathazeke kakhulu ngazo.

Ingabe i-polyvinylpyrrolidone iyingozi?

I-Polyvinylpyrrolidone iyinhlanganisela ye-polymer engeyona i-ionic, ikakhulukazi esetshenziselwa izidakamizwa, ukudla, izimonyo nezinye izinto, ukuphepha kuphakeme kakhulu, uma yengezwa ngokuhambisana nezindinganiso ezifanele, ngokusho kwesilinganiso esivamile sokusetshenziswa, emva kokusetshenziswa ngeke kubangele. ukungakhululeki emzimbeni womuntu, akukho monakalo emzimbeni womuntu.Ngaphansi kwezimo ezijwayelekile, i-polyvinylpyrrolidone ayinabungozi emzimbeni womuntu uma ingezwe ngokuhambisana nezindinganiso zokwengeza ezifanele, kodwa uma idlula izinga lokuphepha, ingase ibe yingozi.

I-PVPine-inertia ehle kakhulu ye-physiological, ayihlanganyeli kumetabolism yomuntu, inokuhambisana ne-biocompatibility ephezulu, futhi ngokuyisisekelo ayinakho ukucasuka esikhumbeni somuntu, amehlo kanye nolwelwesi lwamafinyila.Ngakho-ke, ingasetshenziswa njenge-adhesive, i-ejenti ye-detoxification kanye ne-co-solvent emkhakheni wezokwelapha.I-PVP ngokwayo ayinayo i-carcinogenicity, futhi ingakha ama-complexes anesici se-polyphenol compounds njengama-tannins.Ingasetshenziswa njenge-ejenti ecacisayo kanye ne-stabilizer kabhiya nejusi, futhi emkhakheni wezimonyo, ingasetshenziswa futhi emikhiqizweni yokunakekelwa kwesikhumba efana ne-sunscreen, engathuthukisa umphumela wokumanzisa nokugcoba.Inqobo nje uma kuhambisana namazinga afanele kazwelonke ukwengeza imikhiqizo ehlobene ne-PVP, ukuphepha okuphezulu, akukho miphumela emibi esobala enobuthi emzimbeni womuntu.

I-Polyvinylpyrrolidone ingasetshenziswa futhi ku-lipstick, i-eyeshadow, i-mascara nokunye ukuguqulwa kwezimonyo, ukunciphisa i-pigment nezinye izingxenye zokucasuka kwesikhumba kanye nobuthi, ukhilimu wokushefa nge-polyethylpyrrolidone ungakhuthaza ukuthambisa intshebe kanye nokwanda komsebenzi wokugcoba, wengeze i-polyethylpyrrolidone emikhiqizweni yombala wezinwele umbala, uthuthukise ukuqina kombala.Ukwengeza i-polyvinylpyrrolidone ekwakhiweni kwe-toothpaste kungavimbela i-tartar nokwakheka kwamatshe.

Ingabe i-polyvinylpyrrolidone iphephile esikhumbeni?

Ngenxa yokuthi i-PVP inobuthi obuphansi kakhulu kanye ne-inertia ephezulu ye-physiological, akukho ukucasuka esikhumbeni namehlo, inohlu olubanzi lwezinhlelo zokusebenza ezimonyoni.Indima ye-polyvinylpyrrolidone kumaski obuso: ukusheshisa ukungena kwezithako, i-agent yokugcina izinwele, ukunciphisa ukucasuka komkhiqizo, ukuphepha kokudla okuhle.I-Polyethylpyrrolidone inobudlelwane obuhle esikhumbeni, yakha ifilimu engabonakali ebusweni besikhumba, idlala indima yomswakama we-emollient, ngemva kokwengeza i-polyethylpyrrolidone kumaski, umuzwa wamafutha uzoncishiswa, ukuthambile nokushelela kuyoba ngcono, i-polyethylpyrrolidone. ingasheshisa ukungena kwezithako ze-mask futhi yandise isikhathi sokuhlala sezithako.

Ingabe i-polyvinylpyrrolidone ilungele izinwele?

I-Polyvinylpyrrolidone njengento eluhlaza yezimonyo, kubalulekile ukuyisebenzisela i-ejenti yokugcina isitayela sezinwele, inezinto eziningi ezinhle kakhulu, iyimpahla eluhlaza engabalulekile yokufutha izinwele, ukhilimu wezinwele, i-mousse, i-polyethylpyrrolidone inezici ezinhle zokwakha ifilimu, ingakha into esobala. ifilimu, inokuhlobana okuhle, ukuncibilika kalula ngamanzi, akukho ukucasuka, akukho ukungezwani komzimba nezinto ezithile, futhi inomphumela omuhle wokuvikela izinwele.Kuyi-ejenti yokwenza isitayela kanye ne-ejenti yokwakha ifilimu yemikhiqizo yokunakekelwa komuntu siqu efana ne-mousse nejeli yezinwele.I-Polyvinylpyrrolidone inamathele ezinweleni ukuze zenze ifilimu engabonakali, ilungise isitayela sezinwele, isenze siqine, sigcine sigqamile futhi singenathuli.Lapho izinwele zingamahle, zingakanywa futhi zibunjwe futhi.Uma ingasetshenziswa, ingagezwa nge-shampoo.

Okungenhla kumayelana nokuthiI-PVPiphephile, ngithemba ukuthi lesi sihloko singakusiza.Singabakhiqizi be-pvp abaqeqeshiwe abaneminyaka engaphezu kwe-10 yesipiliyoni sokukhiqiza.Uma unemibuzo, sicela usithinte.
