Most cosmetics contain powders and pigments, which are mainly used to color, protect skin or assist in cleaning. Surface measurement of cosmetic liquids and powders helps with quality control and new product development. 

The functions of emulsification, dispersion, solubilization, foaming and cleaning in cosmetics are all related to the surface and interface energy. The contact angle of raw materials in cosmetics can be measured through a contact angle measuring instrument, thereby helping to judge and analyze their wetting and dispersion behavior.

Contact angle measuring instruments accurately measure the contact angle between a solid surface and a liquid or gas, revealing the microstructure and physical properties of the surface.

Advantages of contact angle measuring instrument SDC-200S:

① Suitable for contact angle measurement of extremely small area samples 

② It can measure the static/dynamic contact angle and surface interface tension of the material surface 

③ Can be used for measuring the surface properties of powder materials 

④ Dual injection system, which can measure surface energy with one click
