Cocoa absolute has a great scent- rich and chocolatey. You can use a little to modify a fragrance, making it a little dirty and a little sweet, without going full out gourmand. With The Lab #7 Cocoa, I didn't add just a little, I added a lot.
I spent a long time figuring out this fragrance. Starting with the base notes, I added patchouli and vetiver for their earthiness. And then let it sit. Added some labdanum to complete the base notes- I love labdanum and its ambery odor. I added some ylang ylang for the middle, and went uh oh- the chocolate brought out the banana notes in ylang ylang. I did not want to create a chocolate covered banana fragrance, though I'm sure there's a market for that.
I let it sit again. Then, to adjust the chocolate-banana middle, I added some clary sage and pimento berry (aka- allspice). I finished it up with spice up at the top, with a good blast of fresh ginger, and dash of woodsy petitgrain.
One problem with chocolate absolute- it does not work well in oils. I let this fragrance sit around for awhile so the chocolate scent could permeate it, and then filtered it before bottling. A lot of the thick brown absolute still made it's way into many of the bottles, and it would be best to shake them to disperse it before applying. I pulled aside the one with the most cocoa absolute hanging around, and it didn't stain or color my pale skin, so that shouldn't worry you. I wouldn't rub the fragrance into your clothes though, since it might stain those. Plus you shouldn't be covering your clothes in oil.
The Lab #7 Cocoa is available from Ivre de Fleurs and Etsy for $10 for a 4ml roller ball.
