Hello
Boswellia Serrata Extract can be dissolved too.
Propylene Glycol and
Butylene Glycol is fine, but Dissolve with 1,3
Propanediol expected poorly And it is not suitable for use with dissolving [the team has never tested it. But give this answer because the manufacturer requires that only
Propylene Glycol and
Butylene Glycol which means the agent other melt will not be able to dissolve well]
