CHARACTERIZATION OF AN EMULSION (STABILITY AND SIZE)

INTRODUCTION

Emulsions are colloidal systems commonly used in the

cosmetics industry. There are inherently unstable but can be

considered as kinetically stable if their destabilization is

slower than their expected shelf life. Moreover, in order to

sell these products, it is necessary to characterize them and

control their quality.

The advantage of the Turbiscan™ technology is that it does

not require any dilution and so samples can be characterized

as they are. In this application note, the particle size and

stability properties are analyzed.
