Without good ties to the perfumery community, and cooperation in sharing information, we artisan and independent perfumers would be working in a vacuum.  I’m fortunate that I have had  interactions with thousands in the community since 2002, and close working relationships with some trusted, knowledgeable perfumers.  It is with them that I have co-authored some papers and distributed these articles to the general perfumery community.  The latest is a publication released by both the Natural Perfumery Institute, an educational resource I head, and the Natural Perfumers Guild, a trade organization I also head.  These two entities allow me rare access to issues and opportunities that affect perfumers. guild-and-institute

There was a technique that we could not find in any books.  Bruce Bolmes has a background in formulating perfumes and making tinctures that allowed him to build a body of techniques to preserve and improve the blending, storage, and quality of accords, perfumes, and tinctures.  He worked selflessly with me and Andrine Olson, the best darn technical editor I’ve ever met and had the pleasure to work with, to produce this paper. Both are adjunct faculty of the NPI and advise on many matters.

We hope that this paper will aid you in elevating your art, if you do not know about testing for, and adjusting the pH of your aromatic treasures. Please share this paper freely, and give us feedback.  We cannot answer individual questions about you refining your process following our suggestions because we are working every day, as you are, on our businesses and we just don’t have the time.  I’m eternally grateful to Bruce and Andrine for the incredible amount of time they have already put into this project.

You can download the paper for free either on the Natural Perfumery Institute or the Natural Perfumers Guild website.  The paper is linked on the left column of the NPI under Free Downloads, and on the Publications page of the NPG. We hope it brings you joy and satisfaction knowing you have a new technique for your studio that can help preserve your accords, perfumes, and tinctures!

    The surface of the skin has a pH of around 5, which is slightly acidic and most skincare is best at the same pH as the skin. Shouldn’t the same be true for perfume? I’ve tested some of my commercial perfumes and they are all coming in around 5.

      Perfume with a pH of 5, that is unheard of, I think your tester is wrong
