  • Measuring pH of emulsion

    Posted by Karo_lina on December 8, 2021 at 1:02 pm

    Hi, 
    I want to ask about pH measuring of emulsion. I found information that measuring pH should be done in finished product since the consumer will use it directly on the skin, but also some of you  dilutes their product and then measure the pH. What is the proper way to do it?

    You should not dilute the product. The only reason to do so would be if you were trying to analyze a solid, and even then the results may not be accurate. Always measure the emulsion as-is.
