If I understand your question correctly you are asking how to increase final pH in your product? (After adding Geogard ECT the pH dropped?)
If so, yes, you can use NaOH (30% solution for example) or other alkaline pH buffer.
-
what pH do you want to establish?
-
Yeah, good point @PhilGeis. I should have mention to be careful to keep the preservative in its functional pH.
-
There is absolutely nothing wrong with pH 3.8 with this preservative. Do you find the for some reason pH 3.8 is too low for your product for some reason? I would leave well enough alone unless you have some really compelling reason to raise the pH above 3.8
-
If you want to increase ph above 4.5, i would suggest add another anti fungal too or change preservative again.
-
can i leave the pΗ for face cream at 3.8? Ι think it's better at 5 -
Yes you can leave it at 3.8. But why did you think you needed to increase it and to what pH?
-
i known that the ph of our face skin is 4,5-5,5right??that’s why i want iti to be ph around 5
-
Are you buffered?
-
what do you mean??
-
Do ingredients in your formula hold the pH steady or is pH readily adjusted?
