Scope

This Technical Report addresses the stability characterization of liquid dispersions (suspensions,
emulsions, foams and mixtures thereof) for applications, such as new product design, optimization
of existing products, quality control during processing and during usage of the product. The stability
of a dispersion in the sense of this Technical Report is defined in terms of the change in one or more
physical properties over a given time period. Stability can be either monitored (determined) in real time
or predicted on the basis of physical quantities related to stability. In the case of very stable dispersions,
procedures that accelerate the changes under consideration or accelerated aging tests administered
over a shorter time scale can be appropriate. Shelf life can be estimated based on the observed rate of
the change in the physical property and the user-required specifications for the product. Guidelines
are given for choosing relevant measurements that can be used for the ranking, identification and
quantification of instability.
