I-Anti-sagging: Kwi-adhesive tile kunye ne-putty powder, i-HPMC inokuthintela ukuchithwa kwezinto kunye nokuphucula ukulawulwa kokwakhiwa.

Isicelo kwishishini lamachiza

Kwintsimi yamachiza, i-HPMC isetyenziselwa ukugquma ithebhulethi, amalungiselelo okukhululwa okuqhubekayo kunye namaqokobhe e-capsule. Izibonelelo zayo ziquka:

Njengesixhobo sokugquma ithebhulethi: I-HPMC ingasetyenziswa njengotyatyazo lwefilimu ukukhusela iziyobisi ekukhanyeni, emoyeni kunye nokufuma, kunye nokuphucula ukuzinza kweziyobisi.

Ukukhululwa okuzinzileyo nokulawulwayo: Kwiipilisi ezikhutshwa ngokuqhubekayo, i-HPMC inokulawula izinga lokukhululwa kwamachiza, ukwandisa ixesha lokusebenza kwamachiza, kunye nokuphucula ukuthotyelwa kwezigulane ngamayeza.

Indawo yeqokobhe le-Capsule: I-HPMC ingasetyenziselwa ukwenza ii-capsules zemifuno, ezilungele abantu abatya imifuno okanye abathengi abaneenkolelo zonqulo.

Isicelo kwishishini lokutya

I-HPMC isetyenziswa ngokubanzi kwiimveliso zobisi, iziselo, iimpahla ezibhakiweyo, njl. njengesongezo sokutya (E464). Izibonelelo zayo ziquka:

I-Thickener kunye ne-emulsifier: I-HPMC ingasetyenziselwa iziselo kunye neesosi ukunyusa i-viscosity kunye nokuzinza kunye nokuthintela ukuhluthwa.

Ukuphucula incasa: Kwimpahla ebhakiweyo, i-HPMC inokunyusa ukuthamba kokutya, ukwenza isonka namaqebengwana athambileyo kwaye afume.

Zinzisa amagwebu: Kwi-ayisikrimu kunye neemveliso zekrimu, i-HPMC inokuzinzisa i-foam kunye nokuphucula ukuthungwa kwemveliso.

Isicelo kushishino lwezithambiso

I-HPMC isetyenziswa kakhulu kwiimveliso zokhathalelo lwesikhumba, ishampu kunye nentlama yamazinyo. Iinzuzo eziphambili zezi zilandelayo:

Isiphumo sokuthambisa: I-HPMC inokwenza ifilimu ethambisayo kumphezulu wolusu ukuthintela ukuphuphuma kwamanzi nokugcina ulusu lufumile.

Ukuzinza kwe-Emulsion: Kwi-lotions kunye ne-skin creams, i-HPMC inokuphucula ukuzinza kwe-emulsion kwaye inqande ukuhlukana kwamanzi oyile.

Ukuphucula i-viscosity: Kwishampu kunye nejeli yokuhlamba, i-HPMC inokuphucula i-viscosity yemveliso kunye nokuphucula amava okusebenzisa.

3. Ukhuseleko lokusingqongileyo kunye nokhuseleko lwe-HPMC

HPMCIthatyathwe kwimicu yendalo yezityalo, inezinto eziphilayo ezifanelekileyo, kwaye iyahlangabezana neemfuno zokhuseleko lokusingqongileyo. Iinzuzo zayo eziphambili zezi zilandelayo:
