I-silica ye-toothpaste grade iyimikhiqizo emihle ethile esetshenziselwa ukukhiqiza i-toothpaste. Ngokwakheka, ingxenye eyinhloko i-silica, okuyi-powder emhlophe, engenambala, engenaphunga. Ukuhlanzeka kwayo okuphezulu, okuqukethwe okuphansi kwezinto ezingafunwa, kuhambisana nezidingo eziqinile zokukhiqiza izinto zokusetshenziswa ze-toothpaste. Ngokwezici zomzimba, usayizi we-silica ye-toothpaste grade uvamise ukuba phakathi kuka-3-12 microns, futhi lezi zilinganiso ziyasiza ekwenzeni imisebenzi ethile kwi-toothpaste. Inokuhlangana okuhle futhi ingahlala ihlukaniswe kahle kwi-paste ye-toothpaste. Ngasikhathi sinye, inenani elifanele lokumunca uwoyela nokumunca amanzi, ingamunca izithako ze-liquid kwi-toothpaste, futhi igcine ukuzinza nokuhlangana okufanele kwe-paste ye-toothpaste. Izici ze-chemistry zizinzile, futhi ngeke kube khona ukuphendulana kwe-chemistry ngaphansi kwemvelo ye-pH ye-toothpaste (inani le-pH ngokuvamile liyi-7-14), futhi ngeke kube khona ukuphazamiseka okungafanele nezinye izithako kwi-toothpaste ezifana ne-fluoride, amafutha, njll. Indima ye-toothpaste inezici ezimbili eziyinhloko. Okokuqala, njengomshini wokuhlikihla, ubhardhness bayo obulinganiselwe bungasusa kahle i-plaque, imfucumfucu yokudla nezinye izinsalela ebusweni bezinyo, futhi ngeke kubangele ukulimala okukhulu ebusweni bezinyo nasezindaweni zokuhlikihla. Okwesibili, ingadlala indima yokwandisa ukusiza ukugcina isakhiwo nesimo se-paste ye-toothpaste, ukuze i-toothpaste ibe lula ukuyiphonsa futhi igcine isimo esihle emathanjeni. Ekukhiqizeni i-toothpaste, ukusetshenziswa kwe-silica ye-toothpaste grade kungenza i-toothpaste ibe nephunga elihle nesimo. Ayikwenzi i-toothpaste ibonakale ingcolile njengamanye ama-abrasives endabuko, ngaleyo ndlela ithuthukisa ulwazi lomsebenzisi. Futhi ubukhazikhazi bayo buphezulu, okusiza ukuthuthukisa umbala we-toothpaste, ukuze i-toothpaste ibonakale ibomvu futhi ibukeke kahle.
