The methods of polarization-optical microscopy and contact angle were used to investigate the phase behavior of liquid-crystalline emulsion systems monododecyl ether of tetraethylene glycol / water / mineral oil. The type and temperature ranges of existence of the mesophase were identified. It is shown that the contact angle method is applicable for identification of phase transitions in the liquid crystal emulsion.
