    Re: Violet Accord Formula

    Professor, it may be that you're only anosmic to beta-Ionone. According to one study, about 50% of people are anosmic to beta-Ionone but not alpha-Ionone:

    Re: Baking soda enfleurage

    I know the feeling, David. Although to be fair, you can't be expected to remember every little detail, especially if your old reference books neglect to mention it. It would rarely be of much use to...

    Re: Sweet fruity top notes

    Nectaryl and Apritone sound good to me. Chefs will often use Apricot jam as a glaze because it lends a sweet, fruity note, without being too distinct. Nectarine and Peach also have a similar...

    Re: Baking soda enfleurage

    Most of the aroma compounds in flowers aren't especially volatile, although everything is relative. Their boiling points are usually towards the upper limit for VOCs (~250 C). Flowers tend not to...

    Re: Sweet fruity top notes
