Ka hoʻohana ʻana i nā hoʻomākaukau lāʻau lapaʻau a i ʻole nā kaʻina hana hoʻomākaukau:

Hoʻohana nui ʻia ka waiʻona Polyvinyl i nā hoʻomākaukau topical a me nā ophthalmic;

Hiki ke hoʻohana ʻia ka waiʻona Polyvinyl ma ke ʻano he mea hoʻopaʻa i loko o nā emulsions.

Hoʻohana ʻia ka waiʻona Polyvinyl ma ke ʻano he mea hoʻopili i nā hoʻomākaukau viscous e like me nā huahana ophthalmic.

Hoʻohana ʻia ka waiʻona Polyvinyl no ka lubrication i loko o nā waimaka hana a me nā hopena lens hoʻopili, a hoʻohana ʻia hoʻi i nā hoʻomākaukau hoʻokuʻu mau ʻia ma ka waha a me nā ʻāpana transdermal.

Hiki ke hoʻohui ʻia ka waiʻona Polyvinyl me ka hopena glutaraldehyde e hana i nā microspheres.
