Abstract
The invention relates to mild toilet soap bars, comprising blends of soap with one or more coactives. There is a need for mild bars which do not have the processing problems associated with the use of superfatting agents and co-actives, which can be made without difficulty on conventional soap production lines without substantial modification of the lines and yet provide a product with reduced harshness while maintaining lathering and structural properties. Moreover, it is desirable that soap bars should not suffer from the defect of grittiness and also have a composition which contains relatively low levels of the significantly more expensive lauric fats. We have determined that in soap bars which comprise at least 25% wt. on total actives of lauric acid soaps; as the balance of the soaps, non-lauric soaps having an iodine value of less than 45; at least 5% wt. on total actives of one or more synergistic mildness active, and, 2-10% on total actives of free fatty acids and are substantially free of cationic polymer skin mildness aids, there is a significant reduction in bar stickiness while maintaining hardness within acceptable limits. Moreover, the lather volume of the bars is increased without the addition of lauric fats and they do not suffer from grittiness.
