High water hard bars comprising combination of type and amount of electrolytes

Abstract

The invention relates to a process to make high water bars with a high speed extrusion process by using specific types and amounts of electrolytes in combination. The bars are produced with no negatives generally associated with use of electrolytes. Disclosed is an extruded soap bar composition wherein the bar comprises: a) 20 to 40% of water; b) 20 to 75% by wt. anhydrous soap; wherein C16 to C24 saturated soap comprises 12% to 45% by wt. of total bar. c) structurants comprises at least from 0.05 to 35% by wt., wherein the specific level of structurants is defined by the level of C16 to C24 saturated soap of (b) such that the total level of said C16 to C24 saturated soap and structurants are greater than 25%, and wherein said structurants are selected from the group consisting of starch, carboxymethylcellulose, inorganic particulates, acrylate polymers and mixtures thereof; d) electrolyte which is a combination of alkali metal chloride; and a secondary electrolytes selected from the group consisting of alkali metal citrate and alkali metal sulfate; and wherein the concentration of alkali metal chloride ([alkali metal chloride]); and of alkali metal citrate ([alkali metal citrate]), alkali metal sulfate ([alkali metal sulfate]) defined by level of water we use as follows: i. [alkali metal chloride]%=0.075×[water]−0.626; and ii. [alkali metal citrate]%=−0.0023×[water]2+0.312×[water]−4.34; iii. [alkali metal sulfate]%=−0.0023×[water]2+0.312×[water]−4.34; or iv. [alkali metal citrate and alkali metal sulfate]=−0.0023×[water]2+0.312×[water]−4.34, wherein the calculated amount of the concentration of the electrolyte is plus or minus 15%.
