Ibanga lansuku zonke lamakhemikhali i-hydroxypropyl methylcellulose i-polymer yokwenziwa eyenziwe nge-cellulose yemvelo ngokuguqulwa kwamakhemikhali. I-Cellulose ether iphuma ku-cellulose yemvelo. Ukukhiqizwa kwe-cellulose ether kuhlukile kuma-polymers okwenziwa. Impahla yayo eyisisekelo i-cellulose, isakhi se-polymer yemvelo.
Ngenxa yemininingwane yesakhiwo se-cellulose yemvelo, i-cellulose ngokwayo ayinalo ikhono lokusabela nge-etherification agents. Kodwa-ke, ngemva kokwelashwa kwe-ejenti yokuvuvukala, izibopho eziqinile ze-hydrogen phakathi kwamaketanga amangqamuzana namaketanga ziyabhujiswa, futhi ukukhululwa okusebenzayo kweqembu le-hydroxyl kuba i-alkali cellulose esebenzayo. Ngemva kokusabela komenzeli ofaka i-etherifying, iqembu -OH liguqulwa libe yiqembu NOMA Thola i-cellulose ether. I-200,000-viscosity hydroxypropyl methylcellulose yezinga lamakhemikhali lansuku zonke le-“Max” iyimpushana emhlophe noma ephuzi kancane, engenaphunga, ayinambitheki futhi engenabuthi. Ingancibilika emanzini abandayo kanye ne-solvent exubile ye-organic matter ukuze yakhe isixazululo se-viscous esisobala.
Uketshezi olusebenzisa amanzi lunomsebenzi ongaphezulu, ukukhanya okuphezulu, ukuzinza okuqinile, futhi akuthintwa i-pH uma incibilika emanzini. Inemiphumela yokuqina kanye ne-antifreeze kuma-shampoos namajeli okugeza, futhi inokugcina amanzi kanye nezakhiwo ezinhle zokwenza ifilimu zezinwele nesikhumba. Ngokukhuphuka okubukhali kwezinto zokusetshenziswa eziyisisekelo, ukusetshenziswa kwe-cellulose (antifreeze thickener) ku-shampoo kanye nejeli yokugeza kunganciphisa kakhulu izindleko futhi kufinyelele umphumela oyifunayo.
