Hello, I usually use PG, but I see in the product description that this one can be used instead of PG and is more gentle. So I'm interested in using it. Thank you.

Hello. Solvent substitution must be tested for solubility. Because each solvent Has the ability to dissolve (or extract) each substance differently. which members must test whether Able to dissolve more or less of the substance that needs to be extracted. (which the solubility is definitely not equal)
