Haa, hydroxyethyl cellulose (HEC) waa hydrophilic, taas oo macnaheedu yahay inay leedahay affinity biyaha oo ay ku milmaan biyaha. HEC waa polymer-ka biyaha ku milma taas oo ka timid cellulose, polymer si dabiici ah u dhacda oo laga helo dhirta. Kooxaha hydroxyethyl ee molecule HEC waxay kordhiyaan milmahooda biyaha iyagoo soo bandhigaya kooxaha hydrophilic (biyaha-jecel) ee lafta dhabarka cellulose.
HEC waxaa sida caadiga ah loo isticmaalaa warshado kala duwan sida dhumuc weyn, binder, iyo stabilizer sababtoo ah biyo-millanteeda aadka u fiican iyo awoodda lagu sameeyo xalal deggan. HEC waxaa loo isticmaalaa alaabada daryeelka shakhsi ahaaneed sida shaambooyinka iyo kiriimyada sidii dhumuc iyo emulsifier, iyo sidoo kale rinjiyada iyo dahaarka sida binder iyo rheology modifier.
Guud ahaan, HEC waa polymer hydrophilic kaas oo ku milma biyaha wuxuuna samayn karaa xalal deggan. Biyo-millanaanta ayaa ka dhigaysa shay faa'iido u leh codsiyada kala duwan halkaasoo biyuhu ay yihiin qayb muhiim ah.
