• Uzinzo lwe-pH: Izinzile kuluhlu lwe-pH oluqala kwi-3 ukuya kwi-11.
• Ukufakwa kwe-Thermal Gelation: Yenza ijeli xa ifudunyezwa ize ibuyele kwisisombululo xa ipholile.

3. Inkqubo yoMveliso

Ukuveliswa kwe-HPMC kubandakanya la manyathelo alandelayo:

1. Ukulungiswa kweCellulose: I-cellulose ecociweyo iphathwa nge-alkali (i-sodium hydroxide) ukuze yenze i-alkali cellulose.
2. Ukufakelwa kwe-ether: I-Methyl chloride kunye ne-propylene oxide ziyaziswa ukuba zisebenze kunye ne-alkali cellulose, zenze i-HPMC.
3. Ukungathathi cala: Umxube wempendulo uyasuswa ukuze kususwe iikhemikhali eziseleyo.
4. Ukuhlanjululwa: I I-HPMC iyahlanjwa, yomiswe, ize igutywe ibe ngumgubo ocolekileyo ukuze isetyenziswe kwiindlela ezahlukeneyo.

1. Ishishini leMithi

• Ukukhutshwa Kweziyobisi Ezilawulwayo: Isetyenziswa njengesixhobo sokubopha nokukhulula iipilisi.
• Iikhaphu: Yenza iifilimu ezinyibilikayo kwiigobolondo zekhaphu zemifuno.
• Iifomyula zamehlo: Isebenza njenge-lubricant kumathontsi emehlweni.

1. Ishishini lokutya

• I-Emulsifier kunye ne-Thickener: Isetyenziswa kwiisosi, kwiidiresi, nakwiziselo ukuze incasa yayo ibe ntle kwaye iqine.
• Iimveliso ezineekhalori eziphantsi: Isebenza njengento yokutshintsha amafutha ngenxa yeempawu zayo zokutyeba.
• Ukubhaka Okungenagluten: Iphucula ukuthamba kwentlama kunye nobungakanani besonka.

1. Ukhathalelo Lobuqu kunye Nezithambiso

• Iimveliso zokhathalelo lolusu: Inika ubume bayo kwaye iphucula ukugcinwa komswakama.
• Ukhathalelo lweenwele: Iphucula uzinzo lwe-foam kwiishampu nakwii-conditioner.
