Abstract
A reusable minimal use soap bar comprising a structural core surrounded by a soap layer composition existing in a solid phase. The soap bar can be single or multiple use, depending on the thickness of the soap layer around the core. After use the structural core is replenished with a fresh coating of soap. A method for stripping any existing soap layer and replenishing the core with a fresh coating of soap for reuse is disclosed.
Claims12
A method for recharging a soap bar comprising a structural core over one or more surfaces of which is deposited a solid layer of soap, said method comprising the steps of:
- contacting the soap bar with a stripping fluid at a temperature above a softening point of said soap and at sufficient pressure to cause any existing soap layer to be stripped from any surfaces of said structural core;
- placing said structural core in a pool of soap composition in a liquid phase and covering at least one surface of said structural core with said soap composition;
- and
- cooling said soap composition to form the solid layer of said soap over said at least one surface of said structural core.
A method for recharging a soap bar comprising a structural core over one or more surfaces of which is deposited a solid layer of soap, said method comprising the steps of:
- placing said structural core in a mold having side walls and a bottom wall defining a desired shape for said soap bar;
- stripping any existing soap layer from said structural core by a wash of liquid at sufficient temperature and pressure to strip said existing soap layer from any surfaces of said structural core;
- transferring a soap composition in a liquid phase into said mold to cover at least one surface of said structural core;
- cooling said soap composition to a solid phase;
- and
- removing said soap bar from said mold.
A method for using a rechargeable soap bar comprising a structural core over one or more surfaces of which is deposited a solid layer of soap, said method comprising the steps of:
- stripping any existing layer of said soap from any surfaces of said structural core;
- depositing a soap composition in a liquid phase to cover at least one surface of said structural core;
- cooling said soap composition to a solid phase;
- and
- after use, recovering said soap bar and repeating said stripping and depositing steps.
