How to calculate the amount of carrier oil for oral drops?

Since the extract is quite potent you can dilute the raw extract in a carrier oil.

First, decide upon the dilution you want of your oral drops. This could be anything from roughly 3-50%. We recommend starting with 10% and then finding the level suitable for your use.
So how do you calculate the amount of carrier oil you need to add to your extract, to make oral drops with a known percentage of extract in it?

You can do it by using the formula : (100-p) / p = x
where p is the “dilution percentage” you want, and x is “parts carrier oil per part extract”

Don’t panic. Here you have a few examples:

– If you want a 20% dilution, the calculation is (100-20)/20 = 80/20 = 4.
Meaning that your mix should be 1 part extract and 4 parts carrier oil.

– If you want a 12% dilution, the calculation is (100-12)/12 = 88/12 = 7,33.
Meaning that your mix should be 1 part extract and 7,33 parts carrier oil.

Let us say, your extraction gave a yield of 1,23 grams extract:

– For a 20% dilution you must add (4 x 1,23 g) = 4,92 g carrier oil.

At 20% dilution, the whole batch would be (1,23+4,92 g) = 6,15 g oral drops.

– For a 12% dilution you must add (7,33 x 1,23 g) = 9 g carrier oil.
At 12% dilution, the whole batch would be (1,23+9 g) = 10,23 g oral drops.
