No ka hoʻohana ʻana i ka hoʻomākaukau lāʻau lapaʻau a i ʻole ka hoʻomākaukau ʻana:

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

Hiki ke hoʻohana ʻia ka waiʻona polyvinyl ma ke ʻano he stabilizer i nā emulsions.

Hoʻohana pū ʻia ka waiʻona polyvinyl ma ke ʻano he tackifier i nā hoʻomākaukau viscous e like me nā huahana ophthalmic.

Hoʻohana ʻia ka waiʻona polyvinyl no ka lubrication i nā waimaka artificial a me nā hoʻonā lens contact, a hoʻohana ʻia hoʻi i ka hoʻomākaukau hoʻokuʻu waha a me nā pā transdermal.

Hiki ke hui pū ʻia ka waiʻona polyvinyl me ka solution glutaraldehyde e hana i nā microspheres.
