hexapus.nl sells methyl ionone (iso)
Jan was also kind enough to help me in sourcing some alpha methyl ionone extra as a special order, which I needed for a specific formula, and could find available nowhere. It's lovely stuff actually and slightly different from the iso, a very clean elegant violet with a dry edge to it and a slight honey-like dry down. I love it.
(I also have extra if anybody needs/wants some. PM please as we can't do splits etc. on this forum)
