ʻO kēlā me kēia lā kemika hydroxypropyl methylcellulose he polymer synthetic i hana ʻia mai ka cellulose kūlohelohe ma o ka hoʻololi kemika. ʻO ka cellulose ether kahi hua o ka cellulose maoli. ʻOkoʻa ka hana ʻana o ka cellulose ether mai nā polymers synthetic. ʻO kāna mea nui loa he cellulose, kahi hui polymer maoli. Ma muli o ke ʻano o ke ʻano o ka cellulose kūlohelohe, ʻaʻohe hiki i ka cellulose pono ke hana me nā mea etherification. Eia naʻe, ma hope o ka hoʻomaʻamaʻa ʻana i ka mea hoʻohuhū, ua luku ʻia nā paʻa hydrogen ikaika ma waena o nā kaulahao molekala a me nā kaulahao, a lilo ka hoʻokuʻu ikaika o ka hui hydroxyl i cellulose alkali reactive. E kiʻi i ka cellulose ether.
ʻO ka hydroxypropyl methylcellulose papa kemika i kēlā me kēia lā he pauka keʻokeʻo a melemele iki paha, a ʻaʻohe ona, ʻono ʻole a ʻona ʻole. Hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu a me ka mea hoʻoheheʻe hui ʻia o ka mea organik e hana i kahi hopena viscous akaka. Loaʻa i ka wai wai ka hana ma luna, ke aniani kiʻekiʻe, kūpaʻa ikaika, a ʻaʻole pili i ka pH ke hoʻoheheʻe ʻia i ka wai. Loaʻa iā ia ka mānoanoa a me nā hopena antifreeze i nā shampoos a me nā gel wai, a he paʻa ka wai a me nā waiwai hana kiʻiʻoniʻoni maikaʻi no ka lauoho a me ka ʻili. Me ka piʻi nui ʻana o nā kumu kumu kumu, hiki i ka hoʻohana ʻana i ka cellulose (antifreeze thickener) i ka shampoo a me ka gel wai hiki ke hōʻemi nui i ke kumukūʻai a hoʻokō i ka hopena i makemake ʻia.
Nā hiʻohiʻona a me nā pono o kēlā me kēia lā kemika cellulose HPMC:
1. ʻO ka huhū haʻahaʻa, ka wela kiʻekiʻe a me ka meaʻawaʻawaʻole;
2. Paʻa ka waiwai pH ākea, hiki ke hōʻoia i kona kūpaʻa ma ka laulā o ka waiwai pH 3-11;
3. Hoʻonui i ka hoʻomaʻamaʻa;
4. E hoʻonui i ka ʻūhā, hoʻopaʻa i ka ʻūhā, hoʻomaikaʻi i ka manaʻo o ka ʻili;
5. Hoʻomaikaʻi maikaʻi i ka wai o ka ʻōnaehana.
ʻO ka laulā o ka hoʻohana ʻana i kēlā me kēia lā kemika cellulose HPMC:
Hoʻohana ʻia i ka shampoo, holoi kino, hoʻomaʻemaʻe maka, lotion, ʻaila, gel, toner, conditioner, nā huahana styling, toothpaste, mouthwash, toy bubble water.
ʻO ka hana o ka cellulose cellulose HPMC i kēlā me kēia lā:
I nā noi cosmetic, hoʻohana nui ʻia ia no ka mānoanoa, foaming, stable emulsification, dispersion, adhesion, hoʻomaikaʻi ʻana i ka hana kiʻiʻoniʻoni a me nā waiwai paʻa wai o nā mea hoʻonaninani, hoʻohana ʻia nā huahana kiʻekiʻe-viscosity no ka mānoanoa, hoʻohana nui ʻia nā huahana haʻahaʻa-viscosity no ka hoʻokuʻu. ka hoʻopuehu a me ka hana kiʻiʻoniʻoni.
ʻO ka ʻenehana HPMC cellulose i kēlā me kēia lā:
ʻO ka viscosity o ka hydroxypropyl methylcellulose kūpono no ka ʻoihana kemika i kēlā me kēia lā he 100,000, 150,000, a me 200,000. E like me kāu kumu hoʻohālikelike, ʻo ka nui o ka hoʻohui i ka huahana maʻamau 3 a 5/1000.
