Synthetic detergent in bar or cake form and the method to manufacture same

Claim 1

A process for making a solid detergent in cake or bar form which consists essentially of A. mixing without heating 400 parts by weight of water and 800 parts by weight of a 50 percent solution of sodium hydroxide; B. adding thereto 3,720 parts by weight of dodecylbenzene sulfonic acid and 300 parts by weight of the monoethanolamide of lauric acid; C. then adding to the mixture 200 parts by weight of melted paraffin wax, 1,650 parts by weight of anhydrous sodium sulfate; D. heating the mixture to about 70* C. and adding 2,920 parts by weight of sodium trimetaphosphate thereto; E. adding 1,520 parts by weight of a 50 percent solution of sodium hydroxide whereby a strong exothermic reaction takes place between sodium trimetaphosphate and the sodium hydroxide causing the temperature of the mixture to increase to above 100* C. and changing the mixture to scales or an expanded slurry and F. then feeding the mixture to a rolling device and drawing the mixture into a solid product.
