Human test panels traditionally are used to qualify new cosmetic products. The obvious advantage is their ability to make judgments on the broadest range of characteristics that will determine the success or failure of a new formulation. In particular, they can identify subjective qualities to conduct objective testing for physical behavior that may not be apparent when using instrumentation; for example, appearance in the container, ease of application, spreadability and retention of position/shape once applied.
