The role of hydroxyethyl cellulose (HEC) in coatings!
Hydroxyethyl cellulose (HEC), a white or light yellow, odorless, non-toxic fibrous or powdery solid, prepared by etherification of alkaline cellulose and ethylene oxide (or chlorohydrin), belonging to the genus Nonionic soluble cellulose ethers. Because HEC has good properties of thickening, susp...Read more -
Research Progress of Cellulose based Edible Films
1. Cellulose is passed by D-glucopyranose β- A linear polymer formed by the connection of 1,4 glycoside bonds. The cellulose membrane itself is highly crystalline and cannot be gelatinized in water or formed into a membrane, so it must be chemically modified. The free hydroxyl at the positions C-...Read more -
Hydroxypropyl methylcellulose HPMC gel temperature problem
Regarding the gel temperature of hydroxypropyl methyl cellulose HPMC, many users rarely pay attention to the gel temperature of hydroxypropyl methyl cellulose. Now hydroxypropyl methyl cellulose is generally distinguished according to its viscosity, but for For some special environments and speci...Read more -
Application and preparation of hydroxyethyl methyl cellulose HEMC
