Hiki ke hoʻoheheʻe ʻia ka HPMC i loko o ka mea hoʻoheheʻe i hui pū ʻia me ka wai anuanu a me nā mea kūlohelohe e hana i kahi hopena viscous akaka. Loaʻa i ka hoʻonā wai ka hana ʻili, ke ʻike kiʻekiʻe a me ke kūpaʻa ikaika. ʻAʻole pili kona hoʻoheheʻe ʻana i ka wai e ka pH. Loaʻa iā ia ka mānoanoa a me nā hopena anti-freezing i ka shampoo a me ka gel wai, a loaʻa ka wai paʻa a me nā waiwai hana kiʻiʻoniʻoni maikaʻi no ka lauoho a me ka ʻili. Me ka hoʻonui nui ʻana o nā kumu kumu, cellulose (antifreeze thickener) hiki ke hōʻemi nui i ke kumukūʻai a loaʻa i nā hopena kūpono ke hoʻohana ʻia i ka shampoo a me ka wai ʻauʻau.
ʻO ka wai anuanu i kēlā me kēia lā ka wai anuanu hydroxypropyl methyl cellulose i kēia mau ʻano huahana:
1. Hana maikaʻi i ka mālama wai. Loaʻa i ka HPMC nā hiʻohiʻona hydrophilic. Hiki iā ia ke mālama i ka paʻa wai kiʻekiʻe i ka paʻi, paʻi a hoʻopili i nā huahana.
2. ʻO ka wai anuanu hydroxypropyl methylcellulose HPMC hiki ke hoʻohana i nā mea kūlohelohe maoli, he hana maʻalahi, haʻahaʻa haʻahaʻa, palekana kaiapuni a me ka palekana.
3. He paʻa ka PH, a paʻa ka viscosity o ka hoʻonā wai ma ka laulā o ka pH3.0 a hiki i ka 11.0.
4. ʻO ka hoʻonā wai o ka huahana he hana ili, emulsification, pale colloid a me ke kūpaʻa pili. ʻO ka haʻahaʻa o ka ʻili he 2% a ʻo ka hoʻonā wai he 42-56dyn/cm.
5. ʻO ka mānoanoa a me ka hoʻoheheʻe wai, hiki ke hoʻoheheʻe koke ʻia i ka wai anuanu, kekahi mau mea hoʻoheheʻe a me nā hui pū me nā mea hoʻoheheʻe organik.
6. Hoʻonui i ka viscosity: i ka wā e hoʻonui ʻia ai kahi liʻiliʻi o ka dissolution, e hoʻokumu ʻia kahi hopena viscous transparent, nona nā hiʻohiʻona o ka hana paʻa a me ka ʻike kiʻekiʻe. E loli ka solubility me ka viscosity. ʻO ka haʻahaʻa o ka viscosity, ʻoi aku ka nui o ke kiʻekiʻe o ka dissolution, hiki ke hoʻomaikaʻi maikaʻi i ke kahe o ka ʻōnaehana.
7. Paʻakai paʻakai maikaʻi loa. ʻO ka HPMC he polymer non-ionic, he paʻa paʻa i loko o ka hopena wai electrolyte a i ʻole ka electrolyte organik.
8. Thermal gelation: i ka wā e wela ai ka wai wai i kekahi mahana, e lilo ia i opaque a hiki i ka hana ʻana o ka flocculation state, kahi e hoʻopau loa ai ka hopena i kona viscosity pono. Eia naʻe, e hoʻololi ʻia i ke kūlana hoʻonā kumu ma hope o ka hoʻoilo. No ka pilikia o ka thermal gel, hilinaʻi nui ka mahana i ke ʻano o ka huahana, ka hoʻonā ʻana a me ka helu wela.
9. He mau waiwai 'ē a'e ko HPMC ma ke kahua o nā noi kemika i kēlā me kēia lā, e like me nā waiwai hana ki'i'oni'oni maika'i loa, ke kū'ē nui o ka enzyme, ka ho'opuehu a me nā waiwai pa'a.
