Worked on the rose yesterday. Gave it some extra sparkle. Really love the first couple hours but want to improve the last few hours of the drydown.
Did some experiments with alpha, beta, and delta damascones; they are all lovely with dry, fruity blackcurrent notes, rose notes, and woodsy nuances. They are related to the ionones and their scents reflect that connection. Their suggested usage level is only 0.02% in the finished product for leave-on skin applications, so that limits their use. And you must consider their total content in all your ingredients, which is more complex when you use natural rose absolutes in combination with the synthetics.
