Nā hiʻohiʻona a me nā pono:

Loaʻa i ka HPMC ka hoʻoheheʻe wai maikaʻi i ka wai anuanu. Hiki ke hoʻoheheʻe ʻia i loko o kahi hoʻonā akaka me ka hoʻoulu ʻana i ka wai anuanu. Ma ka ʻokoʻa, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai wela ma luna o 60 ℃ a hiki ke pehu wale. He etera cellulose non-ionic. ʻAʻole i hoʻopaʻa ʻia kona hopena, ʻaʻole pili me nā paʻakai metala a i ʻole nā ​​mea hoʻohui ionic organik, a ʻaʻole i pane me nā mea maka ʻē aʻe i ka wā o ka hoʻomākaukau ʻana; he ikaika anti-sensitivity, a e like me ke degere o ka hoʻololi 'ana i loko o ka molecular hale hoʻonui, kona Ua oi kū kū'ē i allergies a oi paʻa; ʻaʻole nō hoʻi ka metabolically inert.
