Researchers are improving cosmetic products with the help of novel tribometer measurements.
While many of us In the tribology community concern ourselves with the sliding contact of metallic components, Including their lubrication with oil and all the associated sealing, condition monitoring and additive technologies, we should not forget that tribological issues go far beyond this Into the most personal aspects of our everyday lives.
Tribological problems in the personal-care industry abound, whether they be in the design of hair-care products (which probably also involves some condition monitoring), the development of nail polish, where adhesion and wear phenomena are important issues, or the formulation of skin creams where the lubrication behavior of the cream during application can determine the degree of consumer acceptance.
In a recent paper published In Tribology Letters, Ken Nakano and his co-workers from Yokohama National University and the Kao Corp. in japan have looked into the tribological phenomena involved in the application of cosmetic foundation. A mainstay of the personal-care Industry has been the use of sensory panels that report...
