Post Re: Blending Strength
Hi - You can imagine it like this. There are 30 milliliters in 1 ounce, and typically this is the amount of carrier oil one uses - and can 'factor up from' (meaning if you're making 4oz total, just multiply the essential oil amounts by 4).

If you added 1ml of essential oil to 30ml of Carrier Oil, this would result in a 3.33% concentration of essential oil in the carrier. For simplicity's sake, we just say use 1/3rd ml of essential oil per ounce of carrier to make a 1% concentration. With our measuring pipettes, you can 'eyeball' this, and really 'close enough is close enough'.

You can of course also count drops. Every essential oil has a different number of drops per milliliter coming from a pipette or glass eye dropper. This varies from about 30 to 40 drops per ml depending on the EO. Rather than bog down on getting an exact number, use 12 drops of essential oil for each ounce of carrier oil to give you a 1% concentration.

So even if you use 3 essential oils, you could add 4 drops of each to one ounce of carrier oil, giving you a 1% concentration.

I read your info chart on wintergreen essential oil and it says to "only used topically in dilutions of 25% or less to limit the transdermal absorption to safe levels." Isn't 25% rather high? That's a quarter of the blend.
