HPMC, ama Hydroxypropyl Methylcellulose, maaha wax-soo-saarka dareenka ugu adag ee ereyga.Surfactants waa molecules kuwaas oo leh labadaba biyo-jecel (biyaha-jecel) iyo hydrophobic (biyaha celinaya), waxaana loo isticmaalaa in lagu yareeyo xiisadda dusha sare ee u dhaxaysa laba dareere oo aan qarsoodi ahayn ama inta u dhaxaysa dareeraha iyo adkaha.Surfactants waxaa caadi ahaan loo isticmaalaa warshado kala duwan, oo ay ku jiraan alaabta nadiifinta, alaabta daryeelka shakhsi ahaaneed, iyo daawooyinka, iyo kuwo kale.

Dhanka kale, HPMC waa polymer-ku-saleysan cellulose kaas oo loo isticmaalo codsiyo kala duwan, oo ay ku jiraan daawooyinka, cuntada, iyo alaabta daryeelka shakhsi ahaaneed, iyo kuwo kale.HPMC waxa lagu soo saaraa kiimiko ahaan wax ka beddelka cellulose, kaas oo ah polymer dabiici ah oo laga helo dhirta.Gaar ahaan, HPMC waxa lagu soo saaraa iyada oo lagu beddelayo qaar ka mid ah kooxaha hydroxyl ee cellulose midkood methyl ama hydroxypropyl.Polymer-ka soo baxay waa biyo-milmi kara waxaana loo isticmaali karaa dhumuc weyn, binder, emulsifier, iyo stabilizer, iyo hawlo kale.

In kasta oo aanay ahayn wax-soo-saarka, HPMC waxa ay ku soo bandhigi kartaa sifooyin u eg-suuq-geynta codsiyada qaarkood.Tusaale ahaan, HPMC waxa loo isticmaali karaa in lagu dejiyo emulsions, kuwaas oo isku jira laba dareere oo aan la isku dayin, iyada oo la samaynayo lakab difaac ah oo ku wareegsan dhibcaha hal dareere ah ee dareeraha kale.Lakabkani wuxuu ka hortagi karaa dhibcooyinka in ay isdhajiyaan oo ay ka soocaan inta kale ee isku dhafka ah.Sidan, HPMC waxay u shaqayn kartaa sidii emulsifier, kaas oo ah nooc surfactant ah.

Intaa waxaa dheer, HPMC waxaa loo isticmaali karaa si loo yareeyo xiisadda dusha sare ee biyaha, taas oo ah hantida surfactants.Tusaale ahaan, HPMC waxa loo isticmaali karaa sida dahaarka dusha adag si ay uga dhigaan kuwo badan oo biyo ah, taas oo kordhin karta sifooyinkooda qoynta.Codsigan, HPMC waxay yarayn kartaa xiisadda dusha sare ee biyaha ee dusha dahaarka leh, taas oo hagaajin karta ku-dhejinta dareeraha ama adkaha dusha sare.

Guud ahaan, halka HPMC aanu ahayn dulucda dareenka ugu adag ee ereyga, waxay ku soo bandhigi kartaa sifooyin u eg codsiyada qaarkood.HPMC waa polymer-ka badan oo loo isticmaali karo warshado badan oo kala duwan, iyo sifooyinkeeda gaarka ah waxay ka dhigaan shay qiimo leh qaabab badan.
