Abstract

The term “surface” of a material indicates the interface between a solid or liquid and the air and the term “tensiometry” represent an analytical technique capable to characterize the surface free energy of a solid and the surface tension of a liquid. The new term “surface tensiometry” indicates the analytical technique capable to characterize surface free energy and surface tension using the contact angle method. The main treatments for face skin are mascara, eye contour cream, serum, chemical peel, facial mask, eye shadow, lipstick, foundation, night/day cream. The integrated analytical approach (IAA) for these kinds of cosmetics is still not widely applied because the surface tensiometry is not often used in the beauty farm. The IAA represents an integrated approach to study the bulk chemical composition (e.g., by spectroscopic methods) bulk structure (e.g. by rheological measurements) and surface characteristics (e.g. by surface tensiometry) on the same material sample and at the same time. A deeper investigation on the surface free energy of formulations for face skin treatments could give information on their bioadhesivity with the skin. The surface tensiometry can improve the quality of these cosmetics by a non-invasive and fast way optimizing their industrial production.
