| The ultimate goal of any cosmetic product or method, is a satisfied consumer. Many cosmetic products, either leave-on and/or wash off products, advertise a variety of skin benefits. While expert graders may be trained to use diagnostic equipment or to perceive the difference, consumers usually cannot easily discern whether the claimed benefit is actually delivered, or a quantitative extent to which it is delivered. Skin conditions are typically evaluated subjectively through the senses, particularly through sight and touch. An objective measure of the physical parameters controlling the key attributes would provide a useful tool in the characterization of sensory attributes. We will present a novel method which detects acoustic signals during touching to assess the in-use sensory performance of personal care products and extract specific sensory attributes or sensory profile. We will discuss its applications in selection of surfactants, assessment of personal wash and personal care products, and communication with consumers, etc. |
