Ntawm cov qib ntawm qib kawm txog qib ntawm-cyclodextrin
Hydroxypropyl {0}} cyclodextrin yog ib qho ntawm Cyclodextrin derivatives uas tau kawm ntau yam nyob rau tam sim no. (Qhov ncauj cov) hydroxypropyl -chlodoprin yog dawb amorphous lossis crystalline particle tsis muaj ntxhiab tsw qab. Nws yog ib qho zoo tshaj plaws solubperizer rau kev tso tshuaj thiab cov tshuaj cia siab. Cov khoom no tuaj yeem txhim kho cov dej solubility ntawm cov tshuaj tsis zoo, txhim kho kev ua tshuaj lom neeg, thiab txo cov tshuaj lom neeg lom zem, thiab txo cov tshuaj lom thiab kev phiv tshuaj los ntawm cov tshuaj.
