Initially, proper amount of GMS (Tables 1, 2) was added to the 20 ml of oil and then the mixture was heated to 70°C (GMS is solid at ambient temperature). The corresponding amount of aqueous solution 80 ml was heated separately to 70°C. Emulsification started by adding the hot aqueous phase into the hot oil. At that moment heat supply was turned off and agitation was set at 700 rpm. The impeller was running at 700 rpm, for a total 1.5 min. This period was followed by 30 more minutes of agitation at 700 rpm which was sufficient for the emulsion to cool down to ambient temperature (25°C ± 1°C).
