Enhancement Mechanical Properties of Some Cosmetics and Their Effect on Human Skin by Ultrasonic Technique

Abstract

Some physical properties were  studied such as density, velocity, absorption coefficient, relaxation amplitude, compressibility, modulus of elasticity, and acoustic Impedance for four types of cosmetics available locally before  and after added polymer CMC for these cosmetics the results show that the addition of CMC polymer led to improve these properties, except compressibility decreased due to the addition of polymer, so we can deduce that the addition of polymer leads to improve the characteristics of cosmetics practically .
