Hiki ke hoʻoheheʻe ʻia ka HPMC i loko o ka mea hoʻoheheʻe i hui pū ʻia me ka wai anuanu a me nā mea olaola e hana i kahi hopena viscous moakaka. Loaʻa i ka hopena wai ka hana ʻili, ke ʻano moakaka kiʻekiʻe a me ke kūpaʻa ikaika. ʻAʻole i hoʻopilikia ʻia kona hoʻoheheʻe ʻana i ka wai e ka pH. Loaʻa iā ia nā hopena mānoanoa a me nā hopena anti-freeze i ka shampoo a me ka gel ʻauʻau, a he paʻa wai a me nā waiwai hana kiʻiʻoniʻoni maikaʻi no ka lauoho a me ka ʻili. Me ka hoʻonui nui ʻana o nā mea maka kumu, hiki i ka cellulose (antifreeze thickener) ke hōʻemi nui i ke kumukūʻai a loaʻa nā hopena kūpono ke hoʻohana ʻia i ka shampoo a me ka gel ʻauʻau.
ʻO ka wai anuanu hydroxypropyl methyl cellulose koke o kēlā me kēia lā nā ʻano huahana penei:
1. Hana paʻa wai maikaʻi loa. Loaʻa iā HPMC nā ʻano hydrophilic. Hiki iā ia ke mālama i ka paʻa wai kiʻekiʻe i nā huahana kāpili, kāpili a me nā kāpili.
2. Hoʻohana ka wai anuanu koke hydroxypropyl methylcellulose HPMC i nā mea maka kūlohelohe, nona ka hana akahai, ka huhū haʻahaʻa, ka palekana o ke kaiapuni a me ka palekana.
3. Paʻa iki ka PH, a paʻa ka mānoanoa o ka wai hoʻoheheʻe ma ka pae pH 3.0 a 11.0.
4. Loaʻa i ka hopena wai o ka huahana ka hana ʻili, ka emulsification, ka pale colloid a me ke kūpaʻa pili. ʻO kona ʻili he 2% a ʻo ka hopena wai he 42-56dyn/cm.
5. Hoʻomānoanoa a me ka hoʻoheheʻe ʻia ʻana o ka wai, hiki ke hoʻoheheʻe koke ʻia i ka wai anuanu, kekahi mau mea hoʻoheheʻe organik a me nā hui pū ʻana me nā mea hoʻoheheʻe organik.
6. Hoʻonui i ka viscosity: ke hoʻonui ʻia kahi liʻiliʻi o ka hoʻoheheʻe ʻana, e hoʻokumu ʻia kahi hopena viscous aniani, nona nā ʻano o ka hana paʻa a me ke aniani kiʻekiʻe. E loli ka solubility me ka viscosity. ʻO ka haʻahaʻa o ka viscosity, ʻoi aku ka nui o ke kekelē o ka hoʻoheheʻe ʻana, hiki ke hoʻomaikaʻi maikaʻi i ke kūpaʻa o ke kahe o ka ʻōnaehana.
7. Kū'ē pa'akai maika'i loa. He polymer non-ionic ka HPMC, kahi pa'a i loko o ka hopena wai electrolyte organik a i ʻole ka electrolyte organik.
8. Gelation Thermal: ke hoʻomehana ʻia ka hopena wai i kahi mahana, e lilo ia i opaque a hiki i ka wā e hana ʻia ai kahi kūlana flocculation, kahi e nalowale loa ai ka hopena i kona viscosity kūpono. Eia nō naʻe, e loli ia i ke kūlana hopena mua ma hope o ka hoʻomaʻalili ʻana. No ka pilikia o ka gel thermal, hilinaʻi nui ka mahana i ke ʻano huahana, ka nui o ka hopena a me ka wikiwiki o ka hoʻomehana.
9. Loaʻa iā HPMC nā waiwai ʻē aʻe ma ke kahua o nā noi kemika o kēlā me kēia lā, e like me nā waiwai hoʻokumu kiʻiʻoniʻoni maikaʻi loa, ke kū'ē ʻana o ka enzyme ākea, nā waiwai hoʻopuehu a me nā mea hoʻopaʻa.
