For face wash/ cleanser./ for charcoal face wash.what type of perfume is preferable oil soluble or water soluble?Is perfume performance pH dependent?What factor matters for long lasting effect of Perfume? Any guidance?Thank you.
As far as your ideas for a long lasting perfume, typically and especially when it comes to a rinse off product, you are looking at log P values - the higher the better. It's water solubility basically determines how it is likely to be rinsed off down the drain or by contrast stick and bind to your skin. So in my opinion, your idea of a water soluble perfume is actually the exact opposite of what you need!
