Synthetic Perfume Ingredients

I have almost a thousand different synthetics (see Inventory), but few in large enough quantities to make selling them worthwhile. These three, as far as I can tell, smell the same as when I first bought them. The heliotropin shows slight discoloration on the top crystals, but nothing that would interfere with the aroma. The alpha-irone is about four years old and the heliotropin about two years more. Both have been stored in the refrigerator. If you need something you’ve been unable to find elsewhere, let me know.
