  • Sodium Ascorbyl Phosphate

    Posted by Anna on April 22, 2015 at 1:05 am
    HI every one.
    i found out that my formula is not dissolved completely. I did check, it seems  Sodium Ascorbyl Phosphate  is the problem.

    Can any one give me the advice how to  mix this ingredients in the easiest way?

    Thank you!

    It would help if we knew what type of formula you were making and what other ingredients were in it.

    Hi Perry , MichelleReece 

     i tried to make the sample again and found out that the problem caused fish eye (it getting bigger some day later) because of Burdock root extract (powder) & White willow bark extract(powder)(even i dissolved in warm water first) and use high sheer mixer(Silverson) at 2600prm.
    Can you tell me should i use power extract in the formula ? or is there any way to fix this problem?
    I couldn’t liquid extract in Australia.I will post my formula.
    Thank you1

    I apologize for not seeing your post earlier, @Anna. It didn’t notify me; try putting an @ after the name(s) so we can get notified. :)

    You might not have enough water to dissolve SAP in. I suspect your plant extracts are taking up too much room. Also, SAP is stable at pH 5-8; your formula could be too acidic.

    Are you pre-dissolving the plant extracts in water prior to forming the emulsion or are you adding them in powder form post-emulsification?

    Trry adding the plant extract powders to your aqueous phase prior to forming the emulsion.
    The SAP is heat sensitive, so it should be added post-emulsification at 30C or so.
    Nix the citric acid … your final pH in this formula should be 6.0 to 7.0 for max stability of the Niacinamide and SAP.
