Abstract:
A process for making bars comprising:(1) 20% to 75% by wt. of an anionic surfactant; (2) 4% to 20% fatty add soap or soap fraction having solubility equal to or greater than 82/18 tallow/coconut soap; (3) 4% to 30% free fatty acid; and (4) a compound or compounds which is source of divalent cation when solubilized at a temperature of about 0Â° C. which process comprises mixing (1), (2) and (3) and a compound or compounds which is a source of divalent cation (4), solubilizing said divalent cation at a temperature of about 0Â° C. in order to provide sufficient available cation to interact with soluble soap, react with a transition state formed during the process and thereby increase throughput 10-200%, said throughput being defined by extrusion rate and/or number of bars stamped per minute.
