About Salicylic Acid (normal type) 1. Normally, it is soluble in Glycol as well, whether or not the RM of Salicylic Acid (normal type) will come. From any source I got Salicylic Acid from someone else. Then the seller suggested how to use it that alcohol must be used to dissolve. If using Glycol, there may be a problem of crystallization because the solubility is not as good as alcohol. So I want to know how accurate this explanation is? 2. Continuing from the first question. In the event that Glycol can dissolve BHA without crystallization problem. If using a substance like 1,3- Propanediol is used to dissolve BHA can it be the same?

Thanks for the advice. In the future, will choose another type. But this time, you must use the normal ones that are available first. Then we can use 1,3- Propanediol soluble without precipitating? If so, is there a technique? Would you recommend it? or a method like using normal Glycol to dissolve at all
