Embodiment

[0214] To compare foam and rheological results (hardness), applicants prepared the following bars:

[0215]

[0216]

[0217] Bars 1-7 were prepared according to the invention wherein the main soap base and the shorter chain soap streams were prepared separately and the two streams were combined and mixed at a temperature in the range of 30-45°C. In Comparative Examples A and B, all chain length fats / oils were saponified at once.

[0218] Applicants next compared the lather volume and rheological results of the various bars:

[0219]

[0220] As can be seen from the above data, the hardness values ​​of the bars of the present invention having discrete regions or domains interspersed in the soap matrix are comparable to comparative bars in which the soap fat / oil is saponified together. This ensures that the bars can be extruded and shaped in high throughput manufacturing. Typically, hardness values ​​are in the range of 3.00 to 5.00 Kg measured at 40°C with a 15 mm p...

Abstract

The present invention relates to bars comprising a bar matrix comprising predominantly long chain long soaps and regions or domains interspersed in the matrix comprising predominantly shorter chain soaps. The novel bars of the present invention are stiff enough to survive mass production while delivering significant foam value enhancement benefits, for example, due to delivery of short chain soaps from concentrated areas. Surprisingly, even when the soaps in the concentrated regions represent a small percentage of the total soap oil or fat used, they form an observable kappa phase pattern.

Description

technical field [0001] The present invention generally relates to fatty acid soap bar compositions. It relates to bar compositions having, for example, a region (which may be defined, for example, by a kappa phase pattern) of predominantly shorter chain soaps (prepared and added separately), and which typically accounts for (of the total bar volume) of the final bar composition About 3 to 25%. The main bar matrix (typically about 75% to 97% of the final bar volume) contains mostly higher chain length soaps, which are the typical bricks and mortar of soap bar compositions. By providing bars in which regions of predominantly short-chain soap are interspersed within a matrix of predominantly long-chain soap, Applicants provide a bar that can be extruded well (defined by acceptable hardness values), but still deliver the benefits provided by the shorter chain soaps. benefits (eg, enhanced lather) that would be lost or minimized if the blend of soaps had been prepared in a single...
