A study on Thermodynamic, Acoustic and Elastic properties of aqueous solutions of Hydroxyethyl Cellulose

摘要

Hydroxyethyl cellulose is a thickening and gelling derived from cellulose. It is broadly used in household products, cosmetics and cleaning solutions. Hydroxyethyl cellulose is frequently used with hydrophobic drugs in capsule formulations, to improve the drugs dissolution in the gastrointestinal fluids. Ultrasonic technique is one of the basic non-' destructive methods for evaluation of materials and structures. A significant part of every ultrasonic inspection is the way in which the ultrasonic energy is transferred between the transducer and the tested object. In the present investigation, we have tried to compute the activation energy, ultrasound investigations, elastic property (bulk modulus) and molecular interaction properties of aqueous solutions of Hydroxyethyl cellulose at different concentrations (0.05%, 0.10%, 0.15%, 0.20%, 0.25%, 0.30%, 0.35%, 0.40%, 0.45% and 5%) for different temperatures (303K, 308K, 313K, 318K) by determining the relative viscosity.
