Abstract
An exemplary system and method for providing a handwash composition that changes color after a substantially predetermined period of time is disclosed as comprising colorant particles suspended in a surfactant solution. The colorant particles are configured to rupture after a given amount of time of exposure to shear forces resulting from the mechanical agitation of the surfactant to produce a lather. Upon rupture (or alternatively, adequate abrasion) of the colorant particles, the user observes that the soap lather has changed color—thus indicating that a sufficient amount of time has elapsed and that the hand washing activity has likely achieved its intended purpose.
Claims20
A cleansing composition, said composition comprising:
- a surfactant, said surfactant suitably adapted to produce a lather upon application of mechanical forces to said surfactant;
- a colorant, said colorant substantially segregated from the surfactant such that said colorant comprises at least a plurality of discrete particles;
- said colorant particles optionally mixed with the surfactant prior to dispensing from a containment vessel for subsequent use;
- said colorant particles suitably adapted to change the color of the surfactant lather after a substantially predetermined period of time during which mechanical forces are applied to said colorant particles and said surfactant.
A cleansing composition, said composition comprising:
- a surfactant, said surfactant suitably adapted to produce a lather upon application of mechanical forces to said surfactant;
- a carried material, said carried material substantially segregated from the surfactant such that said carried material comprises at least a plurality of discrete particles;
- said particles optionally mixed with the surfactant prior to dispensing from a containment vessel for subsequent use;
- said particles suitably adapted to change at least one physical property of the surfactant lather after a substantially predetermined period of time during which mechanical forces are applied to said particles and said surfactant.
A method of providing a cleansing composition, said method comprising the steps of:
- providing a surfactant, said surfactant suitably adapted to produce a lather upon application of mechanical forces to said surfactant;
- providing a carried material, said carried material substantially segregated from the surfactant such that said carried material comprises at least a plurality of discrete particles;
- optionally mixing said particles with the surfactant prior to dispensing from a containment vessel for subsequent use;
- said particles suitably adapted to change at least one physical property of the surfactant lather after a substantially predetermined period of time during which mechanical forces are applied to said particles and said surfactant.
