A steam-or hot-water-jacketed kettle is preferred for making wax polishes, as a satisfactory temperature must be maintained to prevent caking of the wax along the sides of the kettle and to avoid discoloration by overheating the wax.

Since morpholine has a flash point of 100'F., it should not be added to the mixture in the presence of open flames. If the wax is melted by means of a gas burner, the gas should be turned off during the addition of the morpholine.
Melt the waxes and stearic acid, add the amine, and maintain the temperature at about 90'C. Add the naphtha slowly and stir until a clear solution is obtained and the temperature is 90 to 95'C. Avoid the use of open flames.
The method of adding the abrasive depends on the type used. An oil-absorbing abrasive, such as tripoli, should be well mixed with the hot naphtha solution of waxes just before the water is added. An abrasi |
