Abstract
There is provided a bar soap having an improved resistance to cracking after exposure to repeated cycles of moistening and drying. The bar soap, which contain greater than 3 wt % glycerin, is prepared from an initial blend of about 60 wt % to about 85 wt % tallow, about 10 wt % to about 40 wt % coconut oil and about 15 wt % to about 35 wt % fatty acid. The present invention also relates to the process of transforming the initial blend into a bar soap having an improved resistance to wet cracking.
Claims7
A method of manufacturing a soap mass that can produce a soap bar that is resistant to cracking, the method comprising the steps of:
- combining about 60 wt % to about 85 wt % tallow, about 10 wt % to about 40 wt % coconut oil, and about 15 wt % to about 35 wt % fatty acid to form a soap blend;
- pre-heating said soap blend;
- reacting said pre-heated soap blend with an amount of sodium hydroxide to produce an incompletely saponified neat soap having from about 1 wt % to about 3 wt % of unreacted triglycerides and from about 5 wt % to about 10 wt % glycerin;
- and
- drying said incompletely saponified neat soap to produce a soap mass comprising about 10 wt % to 15 wt % moisture.
