  Clay mask pH

  Posted by MArchambault on October 15, 2018 at 7:53 pm

  We are working on some clay mask products and finding that the pH’s have a tendency to shift up after they have been adjusted down to 5.50.  They drift the next day to 6 or 6.50 area.  Any advice for how to keep the pH more stable in a clay mask system.

  Metal ion hydrolysis at work. Try using a buffer.
