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.
