An aqueous solution of 8.5 g of silver nitrate dissolved in 50 ml of water was, then, added to the above emulsion to result in a separation into a silver laurate-containing toluene phase and an aqueous phase. After removal of the aqueous phase, the toluene phase was dispersed into 200 ml of ethanol, and then, silver laurate was collected by centrifuging. 12 g of spindle-like silver laurate crystals of a longer diameter of about 3 μ was obtained.
