ʻO ka hoʻomākaukau ʻana i ka emulsion

ʻO ka hoʻoheheʻe ʻana o nā ʻāpana ʻaila liʻiliʻi like ʻole i ka hoʻomaʻamaʻa ʻana a me ka shampoo e hōʻike ana i nā waiwai emulsification kumu i manaʻo ʻia e hōʻike ʻia nā alkyl polyglycosides ma ke ʻano he surfactants nonionic. Eia nō naʻe, pono ka hoʻomaopopo pono ʻana i ke ʻano o ka pae i nā ʻōnaehana multicomponent i mea e loiloi ai i nā polyglycosides alkyl ma ke ʻano he emulsifiers ikaika i hui pū ʻia me nā coemulsifiers hydrophobic kūpono. Piʻi ka hana waena me ka lōʻihi o ke kaulahao alkyl a aia ma kona kiʻekiʻe ma kahi kokoke a i ʻole ma luna o ka CMC me ka waiwai ma lalo o 1 mN/m. Ma ka ʻaila wai/mineral interface, C12-14 APG e hōʻike ana i ka haʻahaʻa haʻahaʻa o ka ʻili ma mua o C12-14 alkyl sulfate lnterfacial tensions o n-decane, isopropyl myristate a me 2-octyl dodecanol ua ana ʻia no nā alkyl monoglucosides maʻemaʻe (C8,C10,C12) a me ko lākou hilinaʻi ʻana o ka polyglycoside ma ka ʻaila alkyl. wehewehe ʻia. Hiki ke hoʻohana ʻia nā polyglycosides alkyl chain medium ma ke ʻano he emulsifiers no nā emulsion o/w i hui pū ʻia me nā emulsifiers hydrophobic co.

ʻOkoʻa nā alkyl polyglycosides mai nā surfactants nonionic ethoxylated no ka mea ʻaʻole lākou e hoʻololi i ka pae wela mai ka ʻaila-i-wai (O/W) i nā emulsions aila-i-wai (W/O). mono-laurate (SML). ʻOiaʻiʻo, ua like loa ke ʻano o ka pae a me ke ʻano o ka ʻōnaehana alkyl polyglycoside emulsifier me ka ʻōnaehana ethoxylates ʻona momona momona inā hoʻohana ʻia ka ratio hui ʻana o ka hydrophilic/lipophilic emulsifier i loko o ka ʻōnaehana non-ethoxylated ma kahi o ka mahana ma ke ʻano o ke ʻano o ke ʻano kī.

ʻO ka ʻōnaehana no ka dodecane, ka wai, Lauryl Glucoside a me Sorbitan Laurate ma ke ʻano he coemulsifier hydrophobic e hana i nā microemulsions ma kahi hui hui o C12-14 APG i SML o 4: 6 a 6: 4 (Figure 1). ʻO nā maʻiʻo SML kiʻekiʻe e alakaʻi i w/o emulsions akā ʻoi aku ka kiʻekiʻe o ka alkyl polyglycoside contents e hana i nā emulsion o/w. ʻO ka hoʻololi ʻana o ka nui o ka emulsifier ka hopena i ka mea i kapa ʻia ʻo "Kahlweit fish" ma ke kiʻikuhi pae, ʻo ke kino i loko o nā microemulsions ʻekolu-phase a me ka huelo microemulsions hoʻokahi-phase, e like me ka nānā ʻana me nā emulsifiers ethoxylated ma ke ʻano he hana o ka mahana. ʻo ka 10% o ka hui emulsifier ua lawa ia e hana i kahi microemulsion hoʻokahi.

ʻAʻole i kaupalena ʻia ke ʻano o ka hoʻololi ʻana o ka manawa o nā ʻano surfactant ʻelua, akā hiki ke ʻike ʻia i loko o ke ʻano o ka ʻōnaehana emulsifying. ʻO ka mea nui, he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa (ma kahi o 10^-3mN/m) i ʻike ʻia me ka hoʻohana ʻana i ka hui C12-14 APG/SML.

Ma waena o nā alkyl glycosides i loaʻa nā microemulsions, ʻo ke kumu o ka hana interfacial kiʻekiʻe ʻo ia ka hydrophilic alkyl glycosides me nā pūʻulu glucoside-poʻo nui a me ka hydrophobic co-emulsifiers me nā pūʻulu liʻiliʻi i hui pū ʻia ma ka hui ʻaila-wai ma kahi ratio kūpono. ʻOi aku ka liʻiliʻi o ka hydration (a me ka nui kūpono o ke poʻo hydration) i ka mahana ma mua o ka hihia me nā surfactants nonionic ethoxylated. No laila, ʻike ʻia ka hoʻopaʻapaʻa interfacial like ʻole no ke ʻano o ka ʻāpana e hilinaʻi iki i ka mahana o ka hui emulsifier non-ethoxylated.

Hāʻawi kēia i nā noi hoihoi no ka mea, ʻaʻole like me nā ethoxylates waiʻona momona, hiki i nā alkyl glycosides ke hana i nā microemulsions paʻa wela. Ma ka hoʻololi ʻana i ka maʻiʻo surfactant, ke ʻano o ka surfactant i hoʻohana ʻia, a me ka ratio o ka aila/wai, hiki ke hana ʻia nā microemulsions me nā waiwai kikoʻī, e like me ke aniani, viscosity, nā hopena hoʻololi, a me nā waiwai huʻa. Co-emulsifier i loko o ka hui 'ana o ka alkyl eter sulphate a me ka non-ion, ka mea i hoonuiia microemulsion wahi ua malamaia, a hiki ke hoʻohana 'ia e formulate concentrate a maikai particle aila-wai emulsions.

Ua hana ʻia ka loiloi ʻana i nā triangles pseudoternary phase o nā ʻōnaehana multicomponent i loaʻa ka alkyl polyglycoside/SLES a me SML me kahi hydrocarbon (Dioctyl Cyclohexane) a me ka alkyl polyglycoside/SLES a me GMO me nā aila polar (Dicaprylyl Ether/Octyl Dodecanol), hōʻike lākou i ka ʻokoʻa a me ka nui o nā wahi. nā ʻāpana hexagonal a no nā ʻāpana lamellar i hilinaʻi ʻia ma ke ʻano kemika a me ka ratio hui ʻana o nā ʻāpana. Inā hoʻopili ʻia kēia mau ʻāpana triangle ma luna o nā huinakolu hana like ʻole e hōʻike ana no ka laʻana i ka ʻano huʻa a me nā waiwai viscosity o nā hui like, hāʻawi lākou i ke kōkua waiwai no ka mea hoʻokumu i ka ʻimi ʻana i nā ʻano microemulsion kikoʻī a i hoʻolālā maikaʻi ʻia no ka laʻana i nā mea hoʻomaʻemaʻe maka a i ʻole ʻauʻau ʻauʻau hou. E like me ka laʻana, hiki ke loaʻa mai kahi hana microemulsion kūpono no ka hoʻomaʻemaʻe hou ʻana i ka ʻauʻau ʻauʻau mai ka triangle phase.
