LOW TMF EXTRUDED SOAP BARS COMPRISING POLYSACHARIDE-POLYOL STRUCTURING SYSTEM

摘要

A low TFM extruded personal washing bar having a continuous phase comprising: a. 20% to less than 45% fatty acid soap in which the fatty acid soap comprises at least 30% saturated fatty acid soaps based on the total weight of the soap and wherein the fatty acid soap has a ratio ROL, defined as the total weight of oleics fatty acids soaps divided by the total weight of the laurics fatty acid soaps which satisfies Eq (1); ROL = (-0.00063(TS2)+0.297(TS)-1.95) ± 15% (1 ) where TS is the weight % fatty acid soap in the composition; b. a structuring system comprising: i) from 10% to 40% by weight of continuous phase of a polysaccharide structurant selected from the group consisting of starch, cellulose and a mixture thereof ii) from 8.0% to 30% by weight of continuous phase of a polyol selected from the group consisting of glycerol, sorbitol and their mixtures, and iii) 0 to 15% by weight of continuous phase of water insoluble particulate material, wherein the weight of polysaccharide structurant divided by the weight of polyol, designated Rsp, is in the range from 0.3 to 5.0 and wherein continuous phase is an extrudable mass having a penetrometer hardness of 3 to 8 Kg and a yield stress of 350 to 2000 kPa measured at a temperature of 4O°C.
