Hello all, Up until this point I've followed recipes exactly or I've stuck to one EO or fragrance per batch, but now I want to start mixing it up. For instance, let's make this entirely theoretical for the sake of conversation. Let's say I'm doing an orange and patchouli blend at 2 parts orange to 1 part patchouli. I run my numbers through Brambleberry's fragrance calculator, and it tells me that I can put a maximum of 1.5oz of 10x orange in my soap and 0.75 oz of patchouli. How much of each EO/FO would I put in then to reach a "safe" amount for each fragrance? Would I be safe to then put the 1.5oz of orange in and 0.75oz of patchouli to get my ratio right and hit my maximums? Or now that I've put two fragrance oils/essential oils in, is that too much since it would total 2.25oz and bordering on unsafe? Am I even doing the math right or is there a rule of thumb for this sort of thing? Many thanks!

For EO's there's this wonderful website: https://www.eocalc.com It lets you calculate how much of a blend you can safely use in any kind of product and it's a great resource to find inspiration for EO blends. Hope this helps!

If you are doing a blend, I usually don't go over 1 ounce of EOs per pound of oils. 2 parts orange would equal .67 oz and 1 part patchouli equals .33 oz.
