Skin constituents as cosmetic ingredients. Part II: A study of bio-mimetic monoglycerides behavior at the squalene-water interface by the 'pendant drop' method in a dynamic mode

摘要

This work aims at presenting the viscoelastic behavior of bio-mimetic monoglycerides used as emulsifier in a mixture made of two non-miscible liquids, squalene and water. The measurement of the interfacial tension, carried out by the "pendant drop method in "dynamic mode, made it possible to characterize these amphiphilic molecules according to the value of their elastic modulus, epsilon, as well as their relaxation time, tau(R).
