The Measuring Principle

The probe contains a motor, a steering unit and the friction head with a plain, smooth Teflon disk. A constant rotational speed is applied onto the skin by the friction head. The torque is mfrictiometerprinzeasured and the result is displayed as Frictiometer units.

Advantages of the Frictiometer

  • Constant pressure on the skin by the weight of the rotating disk
  • Different velocities of rotation can be set
  • The probe is especially sensitive and shows a broad scale of measuring results
  • A notch on the measurement head allows the fixation of different materials on the probe head
  • Measurement on different surfaces is possible (e.g textiles, plastic, metal and many more)
  • It allows quick measurements as well as continuous measurements over a longer period
  • The probe head can easily be cleaned after each measurement

Fields of Application:

There are numerous applications possible:

  • The probe can measure friction of the skin as well as of other surfaces (e.g. textiles, papers, etc.). The measurement is  suitable for comparison measurements, rather than absolute measurements.
  • Skin characterization: The friction of the skin is depending on many parameters (dryness, smoothness, roughness, scaliness and other topographic properties)
  • There is a close correlation between skin friction measurements and some sensorial impressions. A recently published and awarded paper by a Swiss group could well establish this link.
  • Efficacy testing of skin care products: e.g. increasing smoothness, hydration, etc. The measurement is also sensitive to different kind of formulations, e.g. o/w vs. w/o (the w/o emulsions frictio tissuedecrease the frictionary resistance more than the o/w emulsions and the effect is longer lasting)
  • Effects of textiles and papers used on the skin (e.g. diapers, tissue, toilet paper, etc.): Different materials of course have different Frictiometer values. For testing, the material is pulled over the friction head and fixed in the notch. The frictionary resistance of the material may lead to irritation on the skin (which then can be assessed i.e. with the Mexameter®). It is possible to study e.g. the effects of untreated paper tissues on the skin in comparison with paper tissues containing additives
