Good news, you probably got the pure natural material. Most benzoin absolute / benzoin resinoid is sold as 'benzoin pourable', which is a solution of the absolute/resinoid in DPG, DEP or an alike solvent, usualy at 50%. This 'benzoin pourable' is also sold as Benzoin essential oil, but it is of course not an EO!
More good news: though it probably contains a few allergens it is one of the least problematic natural fragrance materials around.
I like it very much, use it a lot when I want a soft balsamic aspect.
In case it was not 100% soluble in alcohol at 10% it was probably the crude resin, not a big problem, simply filter and use the tincture.
