  Neutralize Sulphur Odour?

  Posted by Candace on May 3, 2018 at 10:29 pm

  Does anyone have any ideas on what could be used to neutralize a sulphur odour in a pigmented cream?  I’m aware that it is the ultramarine blue in a cream base with a pH of 5.5 that is creating the off-putting scent.  

  However - we NEED the blue to neutralize orange tones and we prefer the formula to be at a pH below 6.  

  Of course - fragrance or essential oils could mask it.  I’m curious if there is something we can add to prevent this reaction entirely? 

  Thank you!
