Orris concrete question

OK, questions...

I've been given a gift of Orris Concrete (10% in DOA)

Judging by the melting point the DOA is diisopropyl adipate, which isn't very soluble in ethanol.

A little research shows that 'Orris Absolute is produced from the concrete oil of orris by alkali washing in ethyl ether solution to remove the myristic acid which amounts to 85-90% of the concrete oil.' I don't have any ether atm and it's bothersome to make, so what can I do with this stuff? Can anyone suggest a suitable solvent, or could I just use it as is and filter it out later?

The concrete itself is strange stuff. It's not very strong on a strip, but if I leave the strip in a room and return the whole room smells faintly of orris. I also tried blending a little with an equal amount of cypriol (just because) and noticed an odd thing: I know the cypriol is there, because too much of it hurts my nose, but the actual cypriol smell is heavily reduced. Peculiar.

I'd also like to know how much is normally used in a blend, and what it goes with. I'm guessing ionones, but it'd be nice to know for sure.

Anyone have any ideas or comments?

I'd just try shaking it hard for a while in ethanol with some DPG, but that's just me :P

I should have mentioned that the cypriol was at 10% in ethanol. I've just returned to the bottle which has been ageing for a few days, and it smells good. It's as if it's taken the rough edges off the cy but made it 'bigger.'

I'll probably try both those methods, Ambolt and lpp.

That's an interesting book in any case, lp.

I may have answered this somewhere else but anyway I'd recommend IPM (isopropyl myristate) as a solvent for orris concrete. It isn't really a concrete btw, it's technically an essential oil that happens to be solid at room temperature. That is due to the very high proportion of myristic acid present, which is also not very soluble in ethanol, but does add to the fixative effect of orris butter (aka 'concrete', aka essential oil).

A small amount will enhance virtually any floral and it certainly works well with ionones (all of them) but I think it's at it's best when used in combination with other florals (rose, lily of the valley, cyclamen - the lighter more transparent ones rather than the heavy jasmines, tuberose and gardenia types) and a cedarwood base. It's magical with ambrofix too.
