Hello everyone.
I have been dabbling in aromatherapy for years and resionous and base oils were always my favourite. Several years ago I did a few concoctions with these plus a little ylang and what else I had, and what surprise when upon smelling Annick Goutal's Ambre Fetiche recently I noticed a strong resemblance to my benzoin/labdanum/plus something else mix.
So following this I'd be interested in creating my own bases to amplify thinned down versions of vintages or perhaps to layer with soliflores or even hydrolates. In a kind of amateurish Germaine Cellier style.
I have benzoin, Peru balsam, labdanum, frankincense, myrrh, patchouli, galbanum, spikenard, Australian sandalwood (and West Indian), vetiver, cedar, myrtle, carrot seed, elemi, cardamom, black pepper, petitgrain, ylang, geranium of course... planning on getting Siam wood and opoponax, and maybe rose and jasmine at some point. I normally use Pranarom and Oshadhi as they're the easiest chemotyped oils I can get. These are all base and heart oils and I really don't like herbal or citrus notes, except in traces.
I also have a tonka bean to tincture.

I'm not interested in creating a perfume, nor do I think it can be done - projection and body wise - without a significant amount of aroma chemicals - just a simple base in an ancient style.

Any advice or formulas would be very much appreciated!

And if you have an animalic aroma chemical or a tincture to recommend, would be great.
