Some or more properties are shown by emulsions.

(1) Emulsions scatter light and thus exhibit Tyndall effect. 
(2) Brownian motion is also observed in emulsion where size of the particle is too near to the limit of 10m. 
(3) Coagulation (also called de-emulsification) of an emulsion can be done by addition of an electrolyte which would destroy the charge. 
addition of a dehydrating agent (as in W/O). heating, freezing and centrifuging.
