ʻO ka hoʻomākaukau ʻana i ka emulsion commetic 2 o 2

ʻO ka huiʻaila i loko o ka dipropyl ether ma kahi ratio o 3: 1.ʻO ka hydrophilic emulsifier he 5:3 hui ʻana o ka coco-glucoside (C8-14 APG) a me ka sodium laureth sulfate (SLES). (GMO) ʻAʻole hoʻololi ʻia ka wai ma 60%.

E hoʻomaka ana me ka ʻōnaehana ʻaila ʻole a me ka co-emulsifier, ʻo ka hui ʻana o 40% C8-14 APG/SLES i loko o ka wai e hana i kahi aniani wai hexagonal.ʻAʻole hiki ke hoʻomoʻi ʻia ka paʻi surfactant ma 25 ℃.

ʻO kahi hapa liʻiliʻi wale nō o ka hui C8-14 APG/SLES i hoʻololi ʻia me kahi hydrophobic co-surfactant GMO e hana i kahi pae papa me kahi viscosity waena o 23000 mPa·s ma 1s-1.I ka hoʻomaʻamaʻa ʻana, ʻo ia ke ʻano o ka paʻi surfactant viscosity kiʻekiʻe e lilo i mea hoʻoheheʻe surfactant pumpable.

ʻOiai ka hoʻonui ʻia ʻana o ka ʻike GMO, paʻa mau ka pae lamellar.Eia nō naʻe, piʻi nui ka viscosity a hiki i nā pae no ka gel wai i ʻoi aku ma luna o ka pae hexagonal.Ma ke kihi GMO, ʻo ka hui ʻana o GMO a me ka wai e hana i kahi gel cubic paʻa.Ke hoʻohui ʻia ka ʻaila, hoʻokumu ʻia kahi wai hexagonal inverse me ka wai ma ke ʻano o loko.ʻOkoʻa loa ke aniani wai wai hexagonal i nā surfactants a me ke aniani wai lamellar i ka hoʻohui ʻana i ka ʻaila.ʻOiai hiki i ka wai aniani hexagonal ke lawe i ka aila liʻiliʻi loa, ʻo ka ʻāpana lamellar e hoʻonui loa i ke kihi ʻaila.ʻO ka hiki o ka lamellar wai kristal e lawe i ka aila e hoʻonui nui ʻia me ka hoʻonui ʻana i ka ʻike GMO.

Hoʻokumu wale ʻia nā microemulsions i nā ʻōnaehana me nā mea haʻahaʻa GMO.ʻO kahi wahi o nā microemulsions haʻahaʻa haʻahaʻa o / w e hoʻolōʻihi ʻia mai ke kihi APG/SLES ma ke koʻi surfactant/ʻaila a hiki i kahi hui aila o 14%.ʻO ka microemulsion he 24% surfactants, 4 % coemulsifier a me 12% aila, e hōʻike ana i ka ʻaila surfactant concentrate me ka viscosity o 1600 mPa·s ma 1 S-1.

Hoʻopili ʻia ka ʻāpana lamellar e kahi microemulsion lua.ʻO kēia microemulsion he gel waiwai nui me ka viscosity o 20,000 mPa·s ma 1 S.^-1(12 % surfactants, 8% coemulsifier, 20 % aila) a ua kūpono i ka ʻauʻau ʻauʻau hou.ʻO ka hui C8-14 APG / SLES e kōkua i ka hoʻomaʻemaʻeʻana i nā waiwai a me nā huʻihuʻi,ʻoiaiʻo ka huiʻaila e hana i mea hoʻonui i kaʻili. haʻihaʻi i ka wā o ka hoʻohana ʻana. I ka wā o ka holoi ʻana, hoʻoheheʻe ʻia ka microemulsion me nā mea kūpono me ka nui o ka wai, kahi e hoʻokuʻu ai i ka ʻaila a hana i mea hoʻohui i ka ʻili.

No ka hōʻuluʻulu ʻana, hiki ke hoʻohui ʻia nā alkyl glycosides me nā co-emulsifiers kūpono a me nā hui ʻaila e hoʻomākaukau ai i nā microemulsions.Hōʻike ʻia ia e ke aniani, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa mālama kiʻekiʻe a me ka solubility kiʻekiʻe.

ʻO nā waiwai o nā polyglycosides alkyl me nā kaulahao alkyl lōʻihi (C16 a i C22) ma ke ʻano he o/w emulsifiers ʻoi aku ka ʻike.I nā emulsion maʻamau me ka waiʻona momona a i ʻole glyceryl stearate ma ke ʻano he coemulsifier a me ka mea hoʻoponopono kūlike, ʻoi aku ka maikaʻi o ka polyglycosides alkyl kaulahao lōʻihi ma mua o ke kaulahao C12-14 APG i hōʻike ʻia ma luna.Ma keʻano loea, alakaʻi ka glycosidation pololei o ka waiʻona momona C16-18 i ka hui ʻana o ka C16-18 alkyl polyglycoside a me ka cetearyl alcohol kahi e hiki ʻole ai ke hoʻopau piha ʻia ka waiʻona cetearyl e nā ʻenehana maʻamau e pale aku i ke kala a me ka ʻala.ʻO ka hoʻohana ʻana i ka waiʻona cetearyl koena e like me ka co-emulsifier, nā kumu hoʻoheheʻe ponoʻī o / w i loaʻa i ka 20-60% C6/18 alkyl polyglycoside ka mea kūpono loa i ka hoʻomaʻamaʻa ʻana no ka hoʻokumu ʻana i nā creme cosmetic a me nā lotions i hoʻokumu ʻia i nā mea kanu mea kanu.Maʻalahi ka hoʻoponopono ʻana i ka viscosity ma o ka nui o ka alkyl polyglycoside/cetearyl alcohol compound a ʻike ʻia ke kūpaʻa maikaʻi loa, ʻoiai i ka hihia o nā emollients polar loa, e like me nā triglycerides.
