  Lowering natural mud PH 7.0 -> 5.3 with Citric Acid. Unstabilty problem

  Hi!

  Have got good response already 2 times on this forum, so going for nr 3  

  Making a rather simple natural ingredient formulation but ran into with some unstable PH problems. 

  89% - Mineral Sea Mud (92% minerals, 7% organics, 1% carbonates).
  5% - Glycerin
  3% - Jojoba Oil
  1% - Butylene Glycol
  1% - Phenoxyethanol
  0.5% - Citric acid
  0.3% - Xanthan Gum
  0.2% - Heather Fragrance

  Phase A :  mixing 1/2 Glycerin ammount with Citric Acid and then adding to Mineral Sea Mud.

  Phase B : mixing the other 1/2 Glycerin ammount with other ingredients and adding to phase A.

  All cold phases.
  PH drops from 7.0 -> ~4.7-5.3. 

  Desired PH is achieved for body PH and mask application.

  THEN, the PH stays stable for 3 hours and starts slowly to increase until it reaches 7.0 within a 4/5 days.

  Any ideas from where to start or what to do to get PH stable?

  I know that there might be quite a few reactions thanks to natural product and content of trace/heavy metals and organics ( humic acid, amino acid, fulvic acid, proteins etc). But still no harm is asking:)

  Sincerely thankful

  Karel
