I have made a body butter and added 1% citric acid but the ph is 2.2. What can I use to increase the ph. 
Please advise

    What else is in your formula?  Probably NaOH would generally work.

    Why did you add citric acid?
    (Weird, I already replied to that post but somehow my answer isn't there anymore...)
  • This is the formula.  I don’t see any Na0h in the formula. Is 1% citric not recommended 

    water       qs
    glycerin    5%
    Caprylic Capric Triglycerides 10%
    Petrolatum 8%
    Shea Butter 3%
    Cetearyl alcohol 3%
    Parfum qs
    preservative 1%
    Citric acid 1%

    Ph is 2.2

    please advise. I really need to raise ph to 4.5.

    Again, why (= for which purpose, what is citric acid supposed to do in your formula) do you add citric acid?
    See, adding NaOH or the like will solve the problem of a low pH but it may not be the solution you're looking for. There might be better options such as adding less citric acid in the first place. But to answer that, you'd have to be more specific on the 'why'.
  • Pharma, am really new to formulation but I have always believed that one has to add some sort of acid to adjust an aqueous formulation. 
    And citric acid being affordable; has mostly been the acid of choice. 
    Everyday being a school day; please advise on what to do.
    Should I completely get rid of it? Will this help with Ph? 
  • If the pH is currently 2.2 with around 1% citric acid then do some test batches using lower amounts.

    Make some samples using 0.5%, 0.6%, 0.4%, etc.

    To get a pH of 4.5 you will have to experiment with the amount of citric acid present.
  • Thank you Natzam, will try this out.

    Okay. Suppose it's in there as chelate in which case 0.1% is already more than you need and you are free to adjust pH since chelation with citrate works even better at higher pH.
