Consistency, stiffness, processability and flowability are just a
few of the factors that make up the desirable viscous behavior of
a cosmetic sample. They are therefore important parameters for
quality control in all manufacturing processes and in the application. The ROTAVISC series of viscometers allow for the precise
measurement of viscosity, as well as ease of use.
What is the correct viscosity of a cream? That depends on whether, for
example, it should penetrate the skin quickly or form a protective layer
instead. In the first case, the cream improves the smoothness of the skin,
in the second, it protects against infection, for example, if the skin gets
burned. In both situations, the cream should be easy to distribute evenly
while rubbing.
The respective viscous properties with different application requirements
can be checked by measuring the viscosity at different shear rates. In
order to ensure that the cream maintains a consistent level of quality, it
is thus important to control the viscosity of the product under different
