Abstract

The present invention relates to cleansing bars including: a) a cleansing composition; and b) a plurality of discrete elements having a length to diameter ratio of from about 50 to 1 to about 100,000 to 1. The cleansing bars according to the invention have good grippability, exfoliating and cleansing properties and are capable of providing a significant amount of lather in a relatively short period of time. The invention also relates to methods of making and using the cleansing bar described above.

Claims
