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.
  • What are you dissolving SAP in and at what temp?

    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.

    my final pH is 6.2-6.5 . i tried both ways

    - first time i put  white willow bark(16:1) powder, Burdock root extract (4:1) powder in water phase and heat
    up 65ºC, When sample is finished , it look like not dissolved completely. and
    after a week fish eyes (bubble) got bigger and bigger.

    - Second time, i put the powder extract in the cool down phase. the result is
    as the same the first time.

    -Recently (tried twice)  i was pre-dissolving the plant extracts in water
    at 40ºC, and added it in cool down phase.  when it is finished , it is
    more soothy than before, however i still can see very very eys fish(bubble). it
    doesn't like normal cream even the mixing speed this time i creased to 4500prm.

    it is over 3 days now and i do not see any different yet.

    I did make a formula without these powder extracts 4 months ago ( however added
    citric acid, Sodium citrate, Triethanolamine) , i just heck, it likes normal
    cream.obviously must be something wrong.
