Cosmetics & Detergents

• What's the pH of a shampoo?
  
• How do I measure the pH of creams, emulsions?
  

• Are the measurements easy?

Yes, the measurements are easy, when you use an electrode with a sleeve or ground glass joint diaphragm for the reference. Electrodes need special care in samples containing detergents (surfactants).

For routine measurement the new 827 pH lab with Metrosensor Viscotrode (ground joint diaphragm) is first choice.
 

Your system without worries includes the Metrohm model 780 pH Meter and a Metrosensor Viscotrode (ground joint diaphragm).
