Uchungechunge lwe-PVP K
*I-Cosmetic Grade Polyvinylpyrrolidone(I-PVP)zikhona njengempushana nesisombululo samanzi, futhi zihlinzekwa ngesilinganiso esibanzi sesisindo samangqamuzana, zincibilika kalula emanzini, otshwaleni nakwezinye izinyibilikisi zemvelo, i-hygroscopicity ephezulu, umthamo omuhle kakhulu wokwenza ifilimu, ukunamathela kanye nokuzinza kwamakhemikhali, akukho ubuthi.I-PVPasetshenziswa kakhulu ekunakekelweni kwezinwele, ekunakekelweni kwesikhumba nasemikhiqizweni yokunakekelwa komlomo, ikakhulukazi emikhiqizweni yesitayela sezinwele. Uma kubhekwa ububanzi besisindo samangqamuzana, kusukela esisindweni esiphansi sengqamuzana kuya esisindweni samangqamuzana esiphezulu se-PVP esisebenza ekwakhiweni kwemikhiqizo yokunakekelwa kwezinwele ezithambile kuya kweziqinile.
