Isicelo

Ukusetyenziswa kumalungiselelo amayeza okanye iinkqubo zokulungiselela:

Utywala bePolyvinyl lusetyenziswa ikakhulu kumalungiselelo e-topical kunye ne-ophthalmic;.

Utywala bePolyvinyl bunokusetyenziswa njenge-stabilizer kwi-emulsions.

Utywala bePolyvinyl bukwasetyenziswa njenge-tackifier kumalungiselelo e-viscous afana neemveliso ze-ophthalmic.

Utywala bePolyvinyl busetyenziselwa ukuthambisa kwiinyembezi zokwenziwa kunye nezisombululo ze-lens zoqhagamshelwano, kwaye zikwasetyenziswa kumalungiselelo okukhululwa okuzinzileyo ngomlomo kunye neepatches ze-transdermal.

Utywala bePolyvinyl bunokuxutywa kunye nesisombululo se-glutaraldehyde ukwenza i-microspheres.
