Abstract
The invention relates to soap/free fatty acid bars in which high amounts of free fatty acid (i.e., greater than 35%, preferably greater than 40% and ratio of FFA to soap greater than 1:1) and low levels of synthetic may be used. In the bar, the free fatty acid is believed to form a complex which is believed to act as a structurant, thereby allowing less use of synthetic surfactant. The bar should require less synthetic surfactant. Total amount of unsaturated material in soap and fatty acid should be no higher than 15% In a second embodiment of the invention, the bar may be made by a neutralization process whereby fatty acid is combined with caustic (e.g., lower than 50% caustic) to form soap and free fatty acid in defined amounts or proportions.
