  • Homogenizing W/O emulsions

    Hi all,

    I was wondering how much mixing time is needed when homogenizing a W/O emulsion. When there are no polymers in the formula, do I run the risk to break the emulsion with extended mixing? Thank you in advance.

    There are ways to calculate these parameters as part of the design. If you’re not familiar with this, you could make small samples at different speeds and mixing times, measure their viscosity, and put them in the oven to see how stable they are.
