## Abstract

A surfactant free soap bar comprising soap, 0.1 to 2.5% by weight free fatty acid, 3 to 7% by weight talc, and 0.1 to 5% glycerin. The talc can be a macrocrystalline talc having D90≧20 μm and optionally D50≧20 μm or D10≧5 μm. The combination provides increased skin feel and leaves skin looking less dry.
