I have ordered MAP and in the formula I want to put 8%, but I have a problem that it is difficult to dissolve, so I want to ask if To reduce the MAP to 5% then add Ethyl Ascorbic acid 3% instead because I see that it is water soluble as well. Can you do it? vit c can these two be put together? PS. This is about 5% MAP 3% Ethyl Ascorbic acid 1% B5 0.5%Hya Thank you very much.

should not be put together Because the ph value of these two substances There are different working ranges. If put together, it can affect the stability. If the information is useful, please click like instead of thank you. Thank you :D
