Abstract:
Bar composition comprising:(1) 20% to 75% by wt. of an anionic surfactant; (2) 4% to 20% fatty acid soap or soap fraction having solubility equal to or greater than 82/18 tallow/coconut soap; (3) 4% to 30% free fatty acid; (4) compound or compounds which is source of divalent cation when solubilized at a temperature of about 0Â° C. which compound is used in an amount sufficient that, when the divalent source compound is solubilized at a temperature of about 0Â° C., it provides sufficient available cation to interact with soluble soap or fraction such that the level of soluble soap is reduced and an enhancement in bar throughput is achieved, wherein said enhancement is defined by greater extrusion and/or greater number of bars stamped per minute; wherein bar composition maintains lather volume of 150 ml or greater when measured by cylinder shaking method even at levels greater than 1% divalent cation.
