Claims
- 1. 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 0° C. which compound is used in an amount sufficient that, when the divalent source compound is solubilized at a temperature of about 0° 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.
- 2. A composition according to claim 1, comprising 35-60% anionic surfactant.
- 3. A composition according to claim 1, wherein anionic surfactant is acyl isethionate.
- 4. A composition according to claim 1, comprising 6 to 12% fatty acid soap.
- 5. A composition according to claim 1, wherein solubility of tallow/coconut is 1.1 g/l in water at 40° C.
- 6. A composition according to claim 1, wherein divalent cation is a group IIA metal selected from the group consisting of magnesium, calcium, berrylium, strontium, barium and mixtures thereof.
- 7. A composition according to claim 1, wherein improvement in extrusion is 10% or greater, wherein all other variables are substantially the same.
- 8. A composition according to claim 1, wherein improvement in bars stamped per minute is 10% or greater, wherein all the other variables are substantially the same.
