Hoʻomākaukau hoʻomākaukau 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. ka nui, e ka degere o ka polymerization (DP).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 wai/mineral oil interface, C12-14 APG hōʻike i ka haʻahaʻa haʻahaʻa haʻahaʻa 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 ua wehewehe ʻia ko lākou hilinaʻi ʻana i ka solubility o nā alkyl polyglycosides i ka pae ʻaila.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 aila-i-wai (O/W) i ka aila-i-wai (W/O). Akā, hiki i nā waiwai hydrophilic/lipophilic. e kaulike ʻia ma ka hui ʻana me kahi emulsifier hydrophobic e like me glycerin mono-oleate (GMO) a i ʻole sorbitol mono-laurate (SML) dehydrated. ʻōnaehana ethoxylates waiʻona 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 he kīʻaha ʻano hana.

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 huina emulsifier ka hopena i ka mea i kapa ʻia ʻo "Kahlweit fish" i ke kiʻikuhi pae, ʻo ke kino e loaʻa ana i ʻekolu-phase microemulsions a me ka huelo hoʻokahi-phase microemulsions, e like me ka ʻike ʻia me nā emulsifiers ethoxylated e like me ka hana o ka mahana. ʻO ka emulsifying kiʻekiʻe. ʻO ka mana o ka hui C12-14 APG/SML ke hoʻohālikelike ʻia me kahi ʻōnaehana ethoxylate waiʻona momona i hōʻike ʻia ma ka ʻoiaʻiʻo ʻo ka 10% o ka hui emulsifier ua lawa e hana i kahi microemulsion hoʻokahi.

ʻAʻole i kaupalena ʻia ka like ʻana o nā ʻano hoʻololi o ka manawa o nā ʻano surfactant ʻelua, akā hiki ke ʻike ʻia i loko o ka neʻe ʻana o ka ʻōnaehana emulsifying. -14 APG/SML ʻo 4:6, a ʻo ka haʻahaʻa haʻahaʻa o ka ʻilikai.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 kahi 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 loli a me ka laulā. o nā wahi no ka o/w, w/o a i ʻole microemulsions no nā pae hexagonal a no nā ʻāpana lamellar i hilinaʻi ʻia ma ke ʻano kemika a me ka ratio hui ʻana o nā mea.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.
