Abstract

A cleansing pad ( 10 ) is made of a web of fibers, forming a substrate ( 11 ), where the substrate ( 11 ) includes a cleansing agent ( 12 ) therein. The cleansing agent ( 12 ) is a pourable soap. In making the cleansing pad ( 10 ), the cleansing agent ( 12 ) is initially heated from solid form into molten/liquid form, and distributed essentially throughout one or more portions of the substrate ( 11 ) in molten form to coat the fibers in said portions of the substrate ( 11 ). After application of the molten cleansing agent ( 12 ), the substrate ( 11 ) is then allowed to cool such that the molten cleansing agent ( 12 ) solidifies and remains solid at a desired range at and above room temperature, forming the cleansing pad ( 10 ). Thereafter, in use, the cleansing pad ( 10 ) is applied for cleaning an object in conjunction with a solvent such as water. The solvent dissolves the solidified cleansing agent ( 12 ). The cleansing pad ( 10 ) can be used in this manner multiple times without the need for application of additional cleansing agent ( 12 ) to the cleansing pad ( 10 ). As such, the cleansing pad ( 10 ) is a self-contained, long lasting product that maintains its creamy lather during multiple uses and does not require the user to reapply cleansing agents to the cleansing pad ( 10 ) with every use.

Claims (50)

1. A personal cleansing device comprising: (a) a web of fibers forming a substrate and (b), a pourable sodium soap having a melting point of 120° F. to 160° F. impregnated substantially throughout the interior of the substrate, and occupying interstitial spaces between the fibers in a quantity sufficient for multiple uses of the substrate in conjunction with a solvent that dissolves the pourable sodium soap for personal cleansing purposes, wherein the pourable sodium soap comprises:

at least two sodium soaps generated from (i), fatty acids of oils selected from the group consisting of palm oil, palm kernel oil, coconut oil, olive oil, castor oil, safflower oil, and (ii), fatty acids of tallow, and

5% to 35% glycerine and up to 10% propylene glycol, and further wherein the personal cleansing device produces lather in both hard as well as soft water.
