Isicelo

Isicelo emalungiselelweni emithi noma ezinqubweni zokulungiselela:

I-Polyvinyl alcohol isetshenziswa kakhulu ekulungiseleleni ama-topical kanye ne-ophthalmic;.

I-Polyvinyl alcohol ingasetshenziswa njenge-stabilizer kuma-emulsions.

I-Polyvinyl alcohol nayo isetshenziswa njenge-tackifier emalungiselelweni e-viscous njengemikhiqizo ye-ophthalmic.

I-Polyvinyl alcohol isetshenziselwa ukugcoba ezinyembezini zokwenziwa nezisombululo zelensi yokuxhumana, futhi ibuye isetshenziselwe ekulungiseleleni ukukhululwa okuqhubekayo komlomo kanye nama-patches e-transdermal.

Utshwala be-Polyvinyl bungabuye buhlanganiswe nesisombululo se-glutaraldehyde ukuze kwakhiwe ama-microspheres.
