manufacture from different departments of Government is very difficult.
The object of the present invention is to develop the process and to
overcome the disadvantages of the known art and it is simple in nature, more
economical and less hazardous.
These and other objects of the present invention have been achieved by
the process of the present invention

reacting stearates such as glycerol tristreate, stearic acid with glycerine in
a reactor at a temperature of 80°C-160°C while stirring the both components and
slowly adding caustic soda and visinol palmitic acid to obtain glycerol mono
