Well, PC is pure essential oils and absolutes so the oil you are feeling is the essential oils. In many perfumes of same ilk the feeling is much more noticeable due to the higher percentage of oils. To explain why you are aware of the feeling I would say it's due to the fact that a vast majority of wet-shaving splashes on the market are around 2.5 to 4.0% essential oil or fragrance oil per 100ml, I went with the correct and traditional aftershave strength of 6% so that people would get the longest scent time possible (without elevating an aftershave to an EDT or perfume strength which is 8%-16 and higher).
Another factor that is relevant is the purity of the essential oils I use, there are 3 main 'grades' of 1.very expensive and very pure, 2. Commercial - expensive, but below standard levels of ketones, terpenes, etc and 3. Dilute or 'cut' essential oils. The latter 2 categories have less low volatility (heavier) oils and more lighter oils - less oilyness but also much less purity and therefore scent. In all cases I went with number 1 on the list, I don't like impurities and personally I will have the highest purity of desired compounds possible whatever the cost
The notes I talk about, in regard to being high, middle or low are actually a measure of their
volatility which is a concept from both Chemistry and Physics that defines the tendency of a particular substance to vaporize - i.e Bergamot and citrus scents are
high volatility, they vaporize easily while Sandalwood and Vetiver are
low volatility and tend towards resisting vapourisation and therefore last longer as a sense of smell, and on the skin as an oil so as the Pork Chop contains a high percentage of Vetiver essential oil the duration of the oil being present on the skin, and the duration of the scent being detectable by you (and more relevantly by others) is extended.
@alfredus of
@TomG can further explain the concept of volatility in chemistry I am sure and of course correct me if I have misspoken
I could have saved a bit of money and reduced the overall percentage of oils in the alcohol solution too and therefore the amount of oil present, but that would have cut the duration of the scent being detectable and the
silage (pronounced see-yaz) which is the French concept and word for 'trail of scent'. It is a metric used in Perfume to measure the detectable distance and longevity of scents.
It is important to remember another facet of scent, in that after 20 minutes or so your olfactory sense becomes saturated with certain accords of the scents, therefore you effectively cease to smell many of the heavier notes while the top ones remain. Others though can detect them readily providing they too have not become saturated.
Fantastic feedback and review of PC
@nsavage , thank you very much man!
