Calculating maximum fragrance with multiple FO/EO's

[Patty88]

Hi all,

Quick question on mixing FO/EO. I apologize if this has been covered before.

I would like to make an Orange Cedarwood soap. I am planning 2:1 orange to cedarwood in 34oz of oils.

Bramble Berry's fragrance calculator says the maximum Orange 10x I can put in my soap will be about ~2 oz.

And, about 1.7 oz for the Cedarwood, if it matters.

So does this mean I want to do ~0.6oz of Cedarwood to ~1.3oz of the Orange 10x for the maximum? I THINK this would be how to calculate it, (taking the maximum for the biggest chunk of EO/FO then dividing it by my ratio) but just want to be totally sure before I dive in.

Thank you!

That should be fine.
If you want to do something like 1 oz fragrance per pound of oil, you would get to use 2.13 oz total for your batch.

You could use 1.7 oz for the cedarwood and the remaining .43 oz orange (just as an example). But if you only wanted cedarwood for your fragrance, you would still have to limit yourself to 1.7 oz cedarwood for the batch, rather than 2.13 oz because there is some component in the fragrance that isn't recommended at higher levels.

Not too good with words... did I make it more confusing?

If you want to take a deeper dive, I can recommended the EOCALC.com website. She provides a lot of information on how she arrives at the usage rates for the blends.
