It is probably beyond question that the process of making perfumes has components of creativity and of knowlege just as other arts do, e. g., music, and judgement is partly subjective.
I would like to understand better those parts which can be captured numerically but still are relevant for the creation process of a perfume. However, I was not able to find a data bank which holds consistent and complete information about
- odor thresholds in Ethanol for human, as average and standard deviation (if relevant separately for male and female)
- concentration dependence of intensity (as perceived by average human), maybe a curve showing the dependence.
- volatility (under standardized conditions) on a continuous numerical scale, not just top, middle, base note
- solubility in ethanol, DPG, PG measured consistently, preferrably in mass units g/kg at normal conditions (20°C)
It is important that all data were measured under equal conditions, it is hard to compare odor thresholds with different solvents or solubilities at different temperatures. But where are all these numbers for the 4000 ingredients? I know that it is a lot, but I would think that the first thing\tresearch focusses on is to study properties and perception systematically for all ingredients before developing complicated olfactory models.
Are there sources of information which I overlooked?
