Abstract
The present invention encompasses an ultra mild personal cleansing bar that contains small sized solid wax particles of which from 85% to 100% are less than 16 microns in size. Preferably 90% to 100% of the wax particles are from 0.1 to 15 microns in size, and more preferably they are from 0.1 to 10 microns in size. The smaller-sized solid wax particles of the present invention provide better mildness than comparable personal cleansing bars which contain larger wax particles. These smaller wax particles do not negatively impact bar in-use aesthetics, for example, bar lather.
