ʻO ka mea maʻamau i hoʻohana ʻia ʻo ia ka diethanolamide niu. Ua kūpono nā Alkanolamides me nā electrolytes no ka mānoanoa a hāʻawi i nā hopena maikaʻi loa. Alkanolamides

ʻO ka mīkini mānoanoa ka pilina me nā micelles surfactant anionic e hana i kahi wai non-Newtonian. He ʻokoʻa ka hana ʻana o nā alkanolamides like ʻole, a ʻokoʻa hoʻi ko lākou hopena ke hoʻohana wale ʻia a hui pū ʻia paha. Hōʻike kekahi mau ʻatikala i ka mānoanoa a me ka huʻahuʻi o nā alkanolamides like ʻole. I kēia mau lā, ua hōʻike ʻia aia nā alkanolamides i ka pōʻino o ka hana ʻana i nā nitrosamines carcinogenic ke hana ʻia lākou i mea hoʻonaninani. Ma waena o nā haumia o nā alkanolamides he amine manuahi, ʻo ia nā kumu kumu o nitrosamines. I kēia manawa ʻaʻohe manaʻo kūhelu mai ka ʻoihana mālama pilikino e pili ana i ka pāpā ʻana i nā alkanolamides i nā mea hoʻonaninani.

2.5.2 Etera

I ka hana ʻana me ka momona momona polyoxyethylene ether sulfate (AES) ma ke ʻano he mea hana nui, maʻamau, hiki ke hoʻohana ʻia nā paʻakai inorganic e hoʻoponopono i ka viscosity kūpono. Ua hōʻike ʻia nā haʻawina ma muli o ka loaʻa ʻana o nā ethoxylates waiʻona momona ʻole i loko o AES, e hāʻawi nui i ka mānoanoa o ka hopena surfactant.

I kēia manawa, ʻo ka PEG-150 distearate ka mea maʻamau. ʻO nā esters i hoʻohana ʻia ma ke ʻano he mānoanoa he nui nā paona molekala, no laila, loaʻa iā lākou kekahi mau waiwai o nā pūhui polymer. ʻO ka mīkini mānoanoa ma muli o ka hoʻokumu ʻia ʻana o kahi pūnaewele hydration ʻekolu-dimensional i loko o ka pae wai, a laila hoʻokomo ʻia nā micelles surfactant. ʻO ia mau pūhui e hana e like me nā emollients a me nā moisturizers i hoʻohui ʻia i kā lākou hoʻohana ʻana ma ke ʻano he mānoanoa i nā mea hoʻonaninani.

2.5.4 Amine oxides

ʻO Amine oxide kahi ʻano polar non-ionic surfactant, i ʻike ʻia e: i ka wai wai, ma muli o ka ʻokoʻa o ka waiwai pH o ka hopena, hōʻike ia i nā waiwai non-ionic, a hiki ke hōʻike i nā waiwai ionic ikaika. Ma lalo o nā kūlana kūʻokoʻa a i ʻole alkaline, ʻo ia hoʻi, ke ʻoi aku ka pH ma mua o a i ʻole like me 7, aia ka amine oxide ma ke ʻano he hydrate non-ionized i loko o ka wai wai, e hōʻike ana i ka non-ionicity. I ka hoʻonā ʻakika, hōʻike ia i ka cationicity nāwaliwali. Ke emi ka pH o ka hopena ma lalo o 3, ʻike maopopo ʻia ka cationicity o ka amine oxide, no laila hiki ke hana maikaʻi me ka cationic, anionic, nonionic a me zwitterionic surfactants ma lalo o nā kūlana like ʻole. Hoʻopili maikaʻi a hōʻike i ka hopena synergistic. ʻO ka Amine oxide kahi mānoanoa kūpono. Ke hiki i ka pH 6.4-7.5, hiki i ka alkyl dimethyl amine oxide ke hana i ka viscosity o ka hui a hiki i 13.5Pa.s-18Pa.s, oiai hiki i ka alkyl amidopropyl dimethyl oxide Amines ke hana i ka viscosity hui a hiki i 34Pas-49Pas, a ʻo ka hoʻohui ʻana i ka paʻakai i ka mea hope ʻaʻole ia e hōʻemi i ka viscosity.

2.5.5 Nā mea ʻē aʻe

Hiki ke hoʻohana ʻia kekahi helu liʻiliʻi o nā betaine a me nā kopa i mea mānoanoa (e nānā i ka Papa 1). Ua like ko lākou ʻano mānoanoa me nā molekole liʻiliʻi ʻē aʻe, a loaʻa iā lākou a pau ka hopena mānoanoa ma o ka launa pū ʻana me nā micelles ʻeleʻele. Hiki ke hoʻohana ʻia nā kopa no ka mānoanoa i nā lāʻau hoʻonaninani, a hoʻohana nui ʻia ka betaine i nā ʻōnaehana wai surfactant.

2.6 Mānoanoa polymer hiki ke hoʻoheheʻe wai

ʻAʻole pili ʻia nā ʻōnaehana mānoanoa me nā mānoanoa polymeric e ka pH solution a i ʻole ka ʻike electrolyte. Eia kekahi, pono ka liʻiliʻi o nā mānoanoa polymer e hoʻokō i ka viscosity pono. No ka laʻana, pono kahi huahana i kahi mānoanoa surfactant e like me ka aila niu diethanolamide me ka hapa nui o 3.0%. No ka loaʻa ʻana o ka hopena like, lawa wale ka fiber 0.5% o ka polymer maʻemaʻe. ʻAʻole hoʻohana wale ʻia ka hapa nui o nā pūhui polymer wai e like me nā mānoanoa i ka ʻoihana hoʻonaninani, akā hoʻohana ʻia hoʻi e like me nā mea hoʻokuʻu, dispersants a me nā styling agents.

2.6.1 Cellulose etera

ʻO ka cellulose ether kahi mānoanoa maikaʻi loa i nā ʻōnaehana wai a hoʻohana nui ʻia i nā ʻano mea hoʻonaninani. ʻO ka cellulose kahi mea kūlohelohe maoli, aia nā ʻāpana glucoside mau, a ʻo kēlā me kēia ʻāpana glucoside he 3 mau pūʻulu hydroxyl, kahi e hiki ai ke hoʻokumu ʻia nā ʻano derivatives. ʻO nā mea mānoanoa cellulosic mānoanoa ma o nā kaulahao lōʻihi hydration-swelling, a ʻo ka ʻōnaehana cellulose-thickened e hōʻike i ka pseudoplastic rheological morphology. ʻO ka hapa nui o ka hoʻohana ma kahi o 1%.

2.6.2 Polyacrylic acid

He 40 makahiki i hala mai ka wā i hoʻokomo ai ʻo Coodrich iā Carbomer934 i loko o ka mākeke i ka makahiki 1953, a i kēia manawa ua nui aʻe nā koho no kēia pūʻulu o nā mānoanoa (e nānā i ka Papa 1). ʻElua mau hana mānoanoa o polyacrylic acid thickeners, ʻo ia hoʻi ka neutralization thickening a me ka hydrogen bond thickening. ʻO ka neutralization a me ka mānoanoa ka mea e hoʻokaʻawale i ka mānoanoa polyacrylic acidic e hoʻokaʻawale i kāna mau mole a hoʻohua i nā koina maikaʻi ʻole ma ke kaulahao nui o ka polymer. ʻO ka hoʻokuʻu ʻana ma waena o nā hoʻopiʻi kāne like ʻole e hoʻoikaika i nā molekala e hoʻopololei a wehe i kahi pūnaewele. Hoʻokō ka hana i ka hopena mānoanoa; ʻO ka mānoanoa hoʻopaʻa hydrogen ʻo ia ka hui mua ʻana o ka polyacrylic acid thickener me ka wai e hana i kahi mole hydration, a laila hui pū ʻia me kahi hāʻawi hydroxyl me kahi hapa nui o 10% -20% (e like me ka loaʻa ʻana o 5 a ʻoi aku nā hui ethoxy) Non-ionic surfactants) i hui pū ʻia e wehe i nā molekala ʻiʻo i loko o ka ʻōnaehana wai e hana i kahi ʻōnaehana pūnaewele e loaʻa ai kahi hopena mānoanoa. ʻO nā waiwai pH like ʻole, nā neutralizers ʻokoʻa a me ka hiki ʻana o nā paʻakai hiki ke hoʻololi nui i ka viscosity o ka ʻōnaehana mānoanoa. Ke emi ka pH ma lalo o 5, hoʻonui ka viscosity me ka piʻi ʻana o ka waiwai pH; i ka 5-10 ka waiwai pH, aneane loli ka viscosity; akā, ke hoʻomau nei ka piʻi ʻana o ka pH, e emi hou ana ka pono mānoanoa. ʻO nā ion monovalent wale nō e hoʻemi i ka mānoanoa o ka ʻōnaehana, ʻoiai ʻo divalent a i ʻole trivalent ion ʻaʻole hiki ke hoʻoheheʻe wale i ka ʻōnaehana, akā hoʻopuka pū i nā precipitates insoluble ke lawa ka ʻike.

2.6.3 ʻO ke kopa maoli a me kāna mau huahana i hoʻololi ʻia

Hoʻokomo nui ʻia ka ʻōpala kūlohelohe i ka collagen a me nā polysaccharides, akā ʻo ke kāʻei maoli i hoʻohana ʻia ma ke ʻano he mānoanoa ka nui o polysaccharides (e nānā i ka Papa 1). ʻO ka mīkini mānoanoa ka hana ʻana i ʻekolu-dimensional hydration network structure ma o ka hoʻopili ʻana o ʻekolu pūʻulu hydroxyl i loko o ka polysaccharide unit me nā molekole wai, i hiki ai ke hoʻokō i ka hopena mānoanoa. ʻO nā ʻano rheological o kā lākou mau mea hoʻoheheʻe wai ka hapa nui o nā wai ʻaʻole Newtonian, akā ʻo nā ʻano rheological o kekahi mau hoʻonā dilute e pili kokoke ana i nā wai Newtonian. ʻO kā lākou hopena mānoanoa e pili ana i ka waiwai pH, ka mahana, ka ʻike a me ke alo o nā solutes ʻē aʻe i ka ʻōnaehana. He mānoanoa maikaʻi loa kēia, a ʻo ke ʻano maʻamau he 0.1% -1.0%.

2.6.4 Nā polymers anorganic a me nā huahana i hoʻololi ʻia

ʻO nā mea mānoanoa polymer anorganic maʻamau, he ʻekolu ʻāpana ʻāpana a i ʻole kahi hoʻolālā lattice i hoʻonui ʻia. ʻO nā ʻano ʻelua ʻoi aku ka maikaʻi o ka ʻoihana ʻo ka montmorillonite a me ka hectorite. ʻO ke ʻano mānoanoa, ʻo ia ka wā e hoʻopuehu ʻia ai ka polymer inorganic i ka wai, e hoʻokaʻawale nā ​​​​iona metala i loko o ia mea mai ka wafer, i ka wā e hoʻomaka ai ka hydration, pehu ʻo ia, a hope loa ua hoʻokaʻawale loa ʻia nā kristal lamellar, e hopena i ka hoʻokumu ʻana i ka lamellar structure anionic. nā kristal. a me nā ʻiona metala i loko o kahi hoʻokuʻu ʻia colloidal. I kēia hihia, loaʻa i ka lamella kahi hoʻopiʻi maikaʻi ʻole o ka ʻili, a ua hoʻopiʻi ʻia kona mau kihi ma muli o nā mokulele haʻihaʻi lattice.
