@ Jfear You hit the nail on the head...smart move adding garlic. This scent is also one I created, but they did it a disservice by using too much eugenol (clove-like aroma chemical). A little of it imparts a dry musty warm metal smell a lot just makes it sweet and spicy. I tried to get them to reformulate it but too many customers had already ordered it to warrant a resub. Plus they wanted a more rounded fragrance verus something linear in aroma profile. In fact this is one of the big issues with FOs. Most fragrance oils, even the novelty ones, are not nearly as linear or "one-note" as I would personally like them to be. Back on topic, Garlic SOS in particular can offer those same metallic coper aromas and WOULD help in hiding the overused clove-like aspect. So smart move in adding it! For a truer copper metalic you'd probably want to start with a base of safranal or a Saffron EO BOTH of which are VERY expensive...and maybe pair it with a soft balsam, a piney aroma. Try hitting your Metallic Copper with a little Balsam (Christmas Tree aroma) and more Garlic. It should get you pretty close. BTW, sounds like our interests are similar. Shoot me a PM sometime we'll talk novetly fragrances!
