Abstract
A polyaphron dispersion comprising an external phase and polyaphrons having an internal phase, the internal phase comprising (i) a first phase which is liquid and (ii) a second phase which is liquid or gaseous.
Claims19
A polyaphron dispersion comprising:
- from about 5% to about 30% by weight based on the total weight of the polyaphron dispersion of an external phase;
- and
- from about 70% to about 95% by weight based on the total weight of the polyaphron dispersion of polyaphrons having an internal phase, the internal phase comprising:
- (i) a first phase which is liquid, and
- (ii) a second phase which is liquid or gaseous;
- wherein when the internal phase comprises at least two liquid phases, each of the liquid phases is a liquid at room temperature.
