    Hello, I have formulated a micellar water, but I have a problem, when I raise the ph to 5.5, the solution becomes cloudy. How do I fix this problem?

    Why are you trying to raise the pH? If you Micellar Cleanser has a pH below 5.5, better for preservation. There really isn’t any benefit to raising the pH.

      Sorry, what I mean is that when I try to bring the ph from 7.5 to below 6, the solution becomes cloudy

    I second Mark.

    But if you would like to know the reason why it is getting cloudy you would need to provide full formula.

    Could you do a knock-out test, removing your CAPB?

    I’ve been doing this cosmetic science gig for >40 years. Can someone explain to me what the heck is implied, explained or described - preferably in physical chemistry lexicon - by “micellar water”? I’ve long considered this a marketing scam.

    Remove the urea and reduce surfactant level. Urea is going to keep the pH up anyway.
