Talosaga

Fa'aaogāga i sauniuniga fa'afoma'i po'o fa'agasologa o sauniuniga:

E masani ona faʻaaogaina le polyvinyl alcohol i sauniuniga faʻapitoa ma fofo mata.

E mafai ona faʻaaogaina le polyvinyl alcohol e fai ma mea e faʻamautu ai i emulsions.

E faʻaaogaina foʻi le polyvinyl alcohol o se mea e faʻapipiʻi ai i sauniuniga mafiafia e pei o oloa mata.

E fa'aaogaina le polyvinyl alcohol mo le fa'a'asu'uina o loimata fa'apitoa ma vaila'au fa'afeso'ota'i tioata, ma e fa'aaogaina fo'i i sauniuniga tu'u i le gutu mo le fa'asa'olotoina pea ma pa'u transdermal.

E mafai fo'i ona fa'afefiloi le polyvinyl alcohol ma le glutaraldehyde solution e fausia ai ni microspheres.
