A Method for the Preparation of a Jute-batching Emulsion ...

2018-6-6  A method is reported for the preparation of a jute-batching emulsion by using castor oil. The castor oil, warm water at 40°C, and Nonidet (as emulsifying agent) in the proportions of 10:89.5:0.5 were found to be the optimum for preparation of the emulsion. The emulsion was found to be stable, even for as long as seven days.
