VERIFIABLE HAND CLEANSING FORMULATION AND METHOD

摘要

A hand cleansing formulation in the form of a soap/disinfectant (liquid, foam, cream or powder) in solution contains a marker agent (e.g., fluorescent or phosphorescent agent(s)) aggregated with a non-marker binder material. By vigorously scrubbing the hands together, as required by a proper hand washing procedure, the aggregates are dissociated to allow the measurement of the fluorescence/ phosphorescence intensity under an activation light source, i.e., UV, IR. This intensity measurement directly relates to the thoroughness of the hand scrubbing steps, thereby allowing the thoroughness of hand scrubbing during a hand washing event to be judged and monitored.
