10 Ways To...Optimize Rheology To Increase Dispersion / Colloidal / Emulsion Stability

By Malvern Instruments

The following ten points highlight general methods of designing and interpreting rheological tests to optimize sample stability.

These points are particularly applicable to colloidal systems (for which the size of the dispersed phase is <1μm) such as: Emulsions i.e. liquid-in-liquid systems such as routinely used in paints and coatings, foodstuffs, adhesives, agrochemicals, cosmetics, personal care and pharmaceutical formulations Sols i.e. solid-in-liquid systems such as inks, paints and coatings, food and drink, cosmetics and personal care and pharmaceutical formulations.
