Is it permissible to use alcohol to preserve royal jelly, provided it is removed before use?

If Allah forbids something, its benefit is also forbidden. Therefore, it is not permissible to use forbidden alcohol, and everything touched by alcohol is impure, unless it solidifies or turns into vinegar and its intoxicating effect is removed. In that case, it becomes pure and permissible to use. So, if the intoxicating property of alcohol is removed, it becomes pure and permissible to use; otherwise, it is impure and forbidden.
