Detersive efficiency of tetrasodium pyrophosphate-Part I

Summary

Tetrasodium pyrophosphate has been shown to possess the following outstanding advantages as a component in built soaps:

• 1) Ability to increase suds.

• 2) Ability to increase detergency.

• 3) Ability to increase the amount of builder without diminishing the cleansing efficiency of the soap.

• 4) Low pH for use in household soaps.

Final conclusions as to its value in combination with other builders must await completion of the work on ternary and quaternary combinations which are now under way.
