Te Waikawa Waikawa Metilururo (HPMC)He momo cellulose kore-ionic ether tēnei i ahu mai i te cellulose tūturu. Nā tōna haumaru, tōna pumau me tōna hototahi kaha, e whakamahia whānuitia ana i roto i ngā hua matū me ngā hua tiaki kiri o ia rā. Ahakoa he hinu kiri, he kirīmi, he horoi kanohi, he hinu kakara rānei, he mahi nui tā te HPMC ki te pumau o te pūnaha, ki te whakapai ake i te ahua o te kiri me te hanganga kiriata, ā, he tāpiringa maha-mahi noa i roto i ngā mea whakapaipai.
1. Ngā pānga whakamātotoru me te whakahaere rheological
Ko tētahi o ngā mahi tino nui o te HPMC ko te whakamātotoru. I roto i tētahi pūnaha wai, ka taea e ōna mekameka ngota te mimiti i te wai me te whakawhanui, ka whakanui ake i te matotoru o te pūnaha, ā, ka hoatu he pā maeneene, he pā ngawari hoki ki te hua. Kāore i rite ki te carbomer me te xanthan gum, he whakamātotoru koretake te HPMC ka taea te hanga i tētahi matotoru pumau me te kore e whakawhirinaki ki te whakakorenga pH. Nō reira, he tino pai mō ngā tātai tiaki kiri waikawa, waikawa ngoikore rānei, pērā i ngā mea kei roto ko te AHA/BHA, ngā VC derivatives, me ngā essence mā.
Hei tāpiritanga, he tino pai ngā āheinga whakahaere ā-rheological a te HPMC. He iti te matotoru o te hua, ā, he ngāwari ki te whakamahi i te wā e whakapūmau ana, me te pupuri tonu i te hanganga teitei ake i te wā okioki, e āwhina ana i ngā wai, i ngā tiēre rānei kia mau tonu te āhua pumau. He mea tino nui tēnei mō ngā hua e hiahia ana kia maeneene me te whakawhānui, pērā i ngā horoi kanohi, ngā kirimi kanohi, me ngā wai kopare.
2. Te whakau i te emulsification me te tiaki i te whakatārewatanga
I roto i ngā pūnaha hinu-wai pērā i ngā whakamomona me ngā kirimi kanohi, ka taea e te HPMC te whakarei ake i te pumau o te whakamomona mā te whakamātotoru me ngā tikanga tiaki atanga. Ka hangaia e ōna mekameka ngota he paparanga tiaki huri noa i ngā pata whakamomona, ka ārai i te kohikohi o ngā pata hinu, ka whakarei ake hoki i te pumau wera me te pumau rokiroki o te pūnaha. Mō ngā hanganga kei roto he nui te hinu huawhenua, te hinu silicone, ngā marara whakauru hohe rānei, ka taea e te HPMC te whakaiti nui i te wehewehenga me te wehenga hinu, me te whakaroa i te roa o te wā e rongoa ai.
I taua wā anō, ka taea hoki e te HPMC te whakarato i tētahi pānga whakatārewatanga, e āhei ai te horapa ōrite o ngā paura kirikiri (pērā i te hauhā titanium, te hauhā konutea, me te paura pērara) me te kore e tau. He mea whakaū e whakamahia whānuitia ana i roto i ngā hua pēnei i ngā hinu ārai rā, ngā hopi horoi makawe, me ngā paraihe.
3. Whakapai ake i te āhua o te kiri me te wheako tono
He maeneene ahurei te HPMC. Ki te whakatauritea ki ētahi korori tūturu (pērā i te kapia guar me te kapia xanthan), he iti ake te piri, he iti ake hoki te whiri, ka taea ai te hoatu i te hua he ahua hou, he rite ki te wai, ki te tiēre rānei. He tino pai mō te ahua o ngā hua tiaki kiri hou o te kiri "māmā, angiangi, kāore i te taumaha".
Ka hangaia e tōna kirimi wairewa-wai he paninga ngohengohe, ōrite ki te mata o te kiri, e whakarei ake ana i te hinuhinu me te toronga o te hua kua oti, e āhei ai ngā kaiwhakamahi kia māeneene ake, kia ngawari ake hoki te kiri ina pania te hinu kakara, te kirīmi kanohi, te hinu kiri rānei.
4. Ngā pānga hanga kiriata me te whakamakuku
Ka taea e te HPMC te hanga i tētahi kiriata tiaki mārama, ngāwari, me te manawa hoki ki te mata o te kiri, ā, kei a ia ēnei painga e whai ake nei:
Te pupuri i te makuku me te whakamakuku: Whakaitihia te mimiti wai kia mau tonu te makuku o te kiri.
Whakapai ake i te wā pupuri o ngā matū hohe: Ko ngā matū hohe pēnei i te waikawa hyaluronic, te niacinamide, te VC, me te ceramide ka nui ake te tūponotanga ka pā tonu ō rātou pānga ki te mata o te kiri.
Whakapai ake i te āhua o te kiri i muri i te hanganga o te kiriata e te hua: Waihangahia he kiriata whakamakuku pai, kāore e piri, hei whakapai ake i te maeneene tonu o te kiri.
Nā tēnei āhuatanga hanga kiriata ka tino rongonui ai te HPMC i roto i ngā wai kopare, ngā kiriata tio, ngā wai whakapūkara me ngā hua waiho-ki-roto.
5. He ngawari, he tino haumaru, ā, he whānui te urutau
He mea hanga mai i te cellulose tūturu, he tino haumaru te HPMC, he iti te riri, ā, kāore he mate pāwera, e tutuki ana i ngā whakaritenga o ngā hua matū o ia rā mō ngā tātai ngawari. He whānui te awhe urutau pH, ā, kāore e tauhohe ki ngā kai hohe noa, nō reira he hototahi ki te nuinga o ngā kai tiaki kiri, tae atu ki
Ngā huaora (VC, VE, panthenol)
Ngā waikawa (waikawa lactic, waikawa salicylic)
Ngā mea whakamakuku (glycerin, propylene glycol)
Pūnaha surfactant (Ngā horoi kanohi me ngā shampoo)
Ngā tangohanga tipu me ngā matū hohe mahi
Nā te whānui o te hototahitanga ka waiho te HPMC hei tāpiri taketake me te tino auau o te whakamahinga i roto i te umanga matū o ia rā.
6. Whakapai ake i te pumau o te āhua me te kakano o te hua
Kua tino whakapai ake te HPMC i te āhua me te pumau o ngā hua tiaki kiri
Ārai i te mimiti me te wehewehe i te wai i roto i te tiēre, i te kirīmi rānei
Whakarei ake i te mārama me te kanapa
Me whakarite kia ōrite te rere o te tātai
Whakapai ake i te kaha ki te pupuri i te matotoru i muri i te rokiroki mo te wa roa
Nō reira, e whakamahia ana hei whakapai ake i te kakano i roto i ngā wai kopare utu nui, ngā kirimi, me ngā hua tiaki kiri kāore e waiho i roto.
HPMCHe rauemi mata maha-mahi noa iho tēnei i roto i ngā matū me ngā tikanga tiaki kiri o ia rā, ā, he maha ngā āhuatanga o āna mahi pēnei i te whakamātotoru, te whakahaere i te reuma, te whakapūmau me te whakapūmau, te whakatārewatanga, te hanga kiriata, te whakamakuku, me te whakapai ake i te āhua o te kiri. Nā te mea he haumaru teitei, he hototahi kaha, he whānui hoki te urutau ki ngā tikanga, he wāhanga nui tēnei i roto i ngā momo hua tiaki kiri, tae atu ki ngā hinu kiri, ngā hinu kakara, ngā kopare kanohi, ngā horoi, ngā rehu me ngā hinu kiri. Mō ngā hua tiaki kiri hou e whai ana i te āhua kiri ngawari, pumau, me te whakahauora, ko te HPMC te tāpiri matua hei whakarei ake i te kounga o te hua.
