Considering that the average volume of a drop is equivalent to 0.02 ml, consider: 10 drops equivalent to 0.2 ml.
In mixing, the following typical examples can be considered, taking into account that mixtures with a predominance of Glycerin require a greater aromatic fraction.
- 10 ml base product + 35 drops (about 0.7 ml) allow to prepare 10.7 ml at 6.5 % nominal concentration
- 10 ml base product + 50 drops (about 1 ml) allow to prepare 11.0 ml at 9.0 % nominal concentration
- 10 ml of base product + 80 drops (about 1.6 ml) allow to prepare 11.6 ml at 14.0 % of nominal concentration
