izindaba

I-Polyvinylpyrrolidone (PVP)Inombolo ye-cas 9003-39-8, i-pvp iyi-polymer engeyona i-ionic eyikhemikhali ehluke kakhulu, efundwe kahle futhi efundwe kabanzi phakathi kwama-polymer e-N-vinyl amide. Ithuthuke yaba yizigaba ezingezona i-ionic, i-cationic, i-anion 3, ibanga lezimboni, ibanga lemithi, imininingwane yebanga lesi-3 lokudla, isisindo sama-molecule esihlobene kusukela ezinkulungwaneni kuya kwemikhiqizo engaphezu kwesigidi ye-homopolymer, i-copolymer kanye ne-crosslinked polymer, futhi ngezakhiwo zayo ezinhle kakhulu ezihlukile isetshenziswe kabanzi.

Ukusetshenziswa kwe-PVP kubanzi kakhulu, sikhathazekile ngokuphepha kokusetshenziswa komkhiqizo, okulandelayo ukukunikeza inkulumo eningiliziwe ngezinkinga eziningana esikhathazeke kakhulu ngazo.

Ingabe i-polyvinylpyrrolidone iyingozi?

I-Polyvinylpyrrolidone iyinhlanganisela ye-polymer engeyona i-ionic, esetshenziswa kakhulu emithini, ekudleni, ezimonyweni nakwezinye izinto, ukuphepha kuphezulu kakhulu, uma ingezwa ngokuhambisana nezindinganiso ezifanele, ngokwesilinganiso esijwayelekile sokusetshenziswa, ngemva kokusetshenziswa ngeke kubangele ukungakhululeki emzimbeni womuntu, akukho monakalo emzimbeni womuntu. Ngaphansi kwezimo ezivamile, i-polyvinylpyrrolidone ayilimazi emzimbeni womuntu uma ingezwa ngokuhambisana nezindinganiso ezifanele zokwengeza, kodwa uma idlula izinga lokuphepha, ingaba yingozi.

I-PVPine-inertia enhle kakhulu yomzimba, ayihlanganyeli ekusetshenzisweni kwe-metabolism yomuntu, ihambisana kakhulu ne-biochemical, futhi ngokuyisisekelo ayinakho ukucasuka esikhumbeni somuntu, emehlweni kanye nakuma-mucous membranes. Ngakho-ke, ingasetshenziswa njenge-glue, i-detoxification agent kanye ne-co-solvent emkhakheni wezokwelapha. I-PVP ngokwayo ayinayo i-carcinogenicity, futhi ingakha ama-complexes anamakhemikhali e-polyphenol ahlukile njenge-tannins. Ingasetshenziswa njenge-ejenti yokucacisa kanye ne-stabilizer yebhiya nejusi, futhi emkhakheni wezimonyo, ingasetshenziswa futhi emikhiqizweni yokunakekelwa kwesikhumba efana ne-sunscreen, engathuthukisa umphumela wokumanzisa kanye nokugcoba. Uma nje kuhambisana nezindinganiso zikazwelonke ezifanele ukwengeza imikhiqizo ehlobene ne-PVP, ukuphepha okuphezulu, akukho miphumela emibi esobala enobuthi emzimbeni womuntu.

I-Polyvinylpyrrolidone ingasetshenziswa futhi ku-lipstick, eyeshadow, mascara kanye nokunye ukuguqulwa kwezimonyo, ukunciphisa umbala kanye nezinye izingxenye zokucasuka kwesikhumba kanye nobuthi, ukhilimu wokushefa one-polyethylpyrrolidone kungakhuthaza ukuthamba kwentshebe kanye nokwanda komsebenzi wokugcoba, ukwengeza i-polyethylpyrrolidone emikhiqizweni yombala wezinwele kungalungisa umbala, kuthuthukise ukuqina kombala. Ukwengeza i-polyvinylpyrrolidone ekwakhiweni kwamazinyo kungavimbela ukwakheka kwe-tartar kanye namatshe.

Ingabe i-polyvinylpyrrolidone iphephile esikhumbeni?

Ngenxa yokuthi i-PVP inobuthi obuphansi kakhulu kanye ne-inertia ephezulu yomzimba, ayinakucasuka esikhumbeni nasemahlweni, inezinhlobo eziningi zezicelo ezimonyweni. Indima ye-polyvinylpyrrolidone kumaski wobuso: ukusheshisa ukungena kwezithako, i-ejenti yokugcina izinwele, ukunciphisa ukucasuka komkhiqizo, ukuphepha okuhle kokudla. I-Polyethylpyrrolidone inobuhlobo obuhle esikhumbeni, yakha ifilimu engavimbeli ebusweni besikhumba, idlala indima yokuthambisa njenge-emollient, ngemuva kokufaka i-polyethylpyrrolidone kumaski, umuzwa wamafutha uzoncipha, ukuthamba kanye nokushelela kuzoba ngcono, i-polyethylpyrrolidone ingasheshisa ukungena kwezithako zemaski futhi yandise isikhathi sokuhlala kwezithako.

Ingabe i-polyvinylpyrrolidone ilungele izinwele?

I-Polyvinylpyrrolidone njengento eluhlaza yezimonyo, kubalulekile ukuyisebenzisa njenge-ejenti yokugcina izinwele, inezakhiwo eziningi ezinhle kakhulu, iyinto eluhlaza ebaluleke kakhulu yokufutha izinwele, ukhilimu wezinwele, i-mousse, i-polyethylpyrrolidone inezici ezinhle zokwakha ifilimu, ingakha ifilimu esobala, inobuhlobo obuhle, kulula ukuyincibilikisa ngamanzi, ayinakucasuka, ayinayo i-allergy, futhi inomphumela omuhle wokuvikela izinwele. Iyisithako sesitayela kanye ne-ejenti yokwenza ifilimu yemikhiqizo yokunakekelwa komuntu siqu njenge-mousse kanye nejeli yezinwele. I-Polyvinylpyrrolidone inamathele ezinweleni ukuze yakhe ifilimu engabonakali, ilungisa isitayela sezinwele, izenze ziqine, zihlale zikhanya futhi zingabi nothuli. Uma izinwele zingacocekile, zingakanywa futhi zibunjwe futhi. Uma zingasetshenziswa, zingagezwa nge-shampoo.

Lokhu okungenhla kumayelana nokuthiI-PVPkuphephile, ngithemba ukuthi lesi sihloko singakusiza. Singumkhiqizi we-pvp ochwepheshe onolwazi lokukhiqiza olungaphezu kweminyaka eyi-10. Uma unemibuzo, sicela usithinte.
