Need advice on dissolving Salicylic Acid
I had an experiment using Salicylic Acid (SA). I tried to dissolve SA using different solvent but it doesnt seem to dissolve perfectly.
I heat the water up to 70C. The salicylic acid indeed dissolve but when it cools down, it crystallized again.
I add 4g Glycerin in 0.2g SA. After that i put it in the hot bath. It does dissolve but there are some paricals that’s still present. (I think it didnt dissolve completely ?)
3. Alcohol 90%
I add Alcohol into the SA. It seems to dissolve but afterwards, the SA started to stick on the side of beaker glass. So I dont think alcohol dissolve the SA.
4. Mineral oil
I add mineral oil into the SA. Put it in the hot bath. But it doesnt seems to dissolve.
So how to actually dissolve SA ? and if for example, I want to make lotion or perhaps acne spot cream, can a “partially” dissolved SA be used ? For example using the Glycerin SA mixture into the lotion ?
Thanks for the advice ! Very appreciated
