In general to achieve your synergies, the amount of essential oil in a drop varies depending on the dropper used.
For a safe approach, the dilutions indicated by Centro Cauce are defined by a commercial dropper: one drop “from this type of dripper” is equivalent to about 40 milligrams.
1ml = 25 drops
5 ml = 125 drops
15 ml = 375 drops
Below, we can find the equivalences between the recommended dilutions and the number of drops “with a commercial dropper”.
Dilution % | 5ml = 125gt | 10ml = 250gt | 20ml = 500gt | 30 ml = 750gt | 50ml = 1250 gt | 100ml = 2500gt |
1% | 1gt | 2gt | 5 gt | 7 gt | 12 gt | 25gt |
3% | 4 gt | 7 gt | 15 gt | 22 gt | 37 gt | 75 gt |
5% | 6 gt | 12 gt | 25 gt | 37 gt | 62 gt | 125 gt |
7% | 9 gt | 17 gt | 35 gt | 52 gt | 87 gt | 175 gt |
10% | 12 gt | 25 gt | 50 gt | 75 gt | 125 gt | 250 gt |
15% | 19 gt | 37 gt | 75 gt | 112 gt | 187 gt | 375 gt |
20% | 25 gt | 50 gt | 100 gt | 150 gt | 250 gt | 500 gt |
30% | 37 gt | 75 gt | 150 gt | 225 gt | 375 gt | 750 gt |
50% | 62 gt | 125 gt | 250 gt | 375 gt | 625 gt | 1250 gt |
But be careful because usually in the literature:
1 drop = 30mg
1ml = 30 drops
In pharmacy, the reference is the drop codex
1 drop codex = about 20-25 mg
1ml = 40-50 drops
Now we have all the correspondences to achieve your synergies and enjoy the benefits of essential oils.
