Abstract
A personal cleansing composition includes a carrier, and a first plurality of beads entrained in the carrier. The beads impart, to a user applying the cleansing composition with hand rubbing force, perceivable tactility for a limited predetermined duration that corresponds to a minimum adequate cleansing time period. In accordance with another embodiment of the present invention, the personal cleansing composition further includes a second plurality of beads entrained in the carrier. The second plurality of beads imparts to the user a perceivable change in color for the cleansing composition for a second limited predetermined duration that is substantially equal to the duration that the tactility imparted by the first plurality of beads is perceivable to the user.
