Background

Hydroxyethyl cellulose is a non-ionic, water soluble, modified cellulose polymer used as a thickening agent for aqueous cosmetic and personal care formulations.

Stabilization of graphene oxide in physiological solution is performed using hydroxyethyl cellulose to make the resultant nanohybrid suitable for targeted drug delivery purposes. Hydroxyethyl cellulose effectively stabilizes graphene oxid in electrolyte solutions and the mechanism of stabilization appears to be depended on hydroxyethyl cellulose content. Hydroxyethyl cellulose content in the nanohybrid plays an important role in final application to make it applicable either as a carrier for controllable drug release or as a folate-targeted drug carrier[1]. Hydroxyethyl cellulose shows superior cryoprotective effects on LDH during freeze thawing, and considerable lyoprotective effects during the freeze drying process. Annealing has limited influence on the stabilizing effect of hydroxyethyl cellulose. The extensive reconstitution times of the hydroxyethyl cellulose lyophilisates could be greatly improved by incorporation of the surfactant Tween 80 into the formulations prior to freeze drying[2].
