Correlating Water Contact Angles and Moisturization/Sensory Claims

A link has been found between the contact angle of water on a particular substrate treated with selected commercial moisturizers and the moisturization claims associated with those moisturizers. A test methodology was developed using measurements of the contact angle of water to quantify the effects on the surface properties of a skin-substitute substrate when skin care products were applied to the substrate. This methodology can be used as an effective tool for optimizing product development, differentiating among skin care products, competitive benchmarking and selecting prospective candidates for human studies.
