Crospovidone
Umxhasi woPhandoCrospovidone yi-PVP edibeneyo, i-PVP enganyibilikiyo, i-hygroscopic, ayinyibiliki emanzini kunye nazo zonke ezinye izinyibilikisi eziqhelekileyo, kodwa idumba ngokukhawuleza kwi-solutbition enamanzi ngaphandle kwejeli evela kwi-gel. ihlelwe njengeUhlobo lweCrospovidone Akunye noHlobo B ngokobungakanani bamasuntswana ahlukeneyo.
Iiparamitha ezingundoqo zobuGcisa:
| Imveliso | Uhlobo lweCrospovidone A | CrospovidoneUhlobo B |
| Imbonakalo | Umgubo omhlophe okanye omthubi-mhlophe okanye iiflakes | |
| Izaziso | A.Ukufunxwa kwe-infrared | |
| B.Akukho mbala ubhlowu uphuhlisayo. | ||
| Ukumiswa kwe-CA kwenziwa kwaye akukho sisombululo sicacileyo sifumaneka ngaphakathi kwe-15 min. | ||
| D.Ubuninzi bamasuntswana akuluhlu lwe-50 ~ 300 μm luhlobo A, uninzi lwamasuntswana akuluhlu lwe-5 ~ 50 μm | ||
| Ukunyibilika | Ngokuqhelekileyo ayinyibiliki emanzini, etywaleni nakwi-methylene chloride | |

Usetyenziso:
I-Crospovidone isetyenziswa ngokubanzi njenge-1) i-agent edibeneyo, i-2) i-Stabilizer yokumiswa, i-3) i-Absorbent yokufuma, i-4) i-Complextant ye-Polyphenols kunye ne-Tannin kwi-extract formulations.

Usetyenziso:
Enkosi kwiipropathi zayo ezinganyibilikiyo emanzini nakwezinye izinyibilikisi eziqhelekileyo, i-PVPP isebenza ngokubanzi njengezizinzisi kunye nesicacisi seBeer/iWayini kunye nezinye iimveliso zesiselo, inokususa iipolyphenols kunye ne-tannins izinto ngexesha leBeer/Wayini/yeSiselo.
