ʻO Povidone
ʻO Povidone he homopolymer o 1-vinyl-2-pyrrolidone (ʻO Polyvinylpyrrolidone), hiki ke hoʻoheheʻe ʻole ʻia i ka wai, i ka ethanol (96%), i ka methanol, a me nā mea hoʻoheheʻe ʻino ʻē aʻe, hiki ke hoʻoheheʻe ʻia me ka acetone. i ke kaupaona mole kiʻekiʻena, i hōʻike ʻia e K Value, me ka hygroscopisty maikaʻi loa, ke kiʻi ʻoniʻoni, ka mea hoʻopili, ka paʻa paʻa kemika a me nā ʻano palekana palekana.
