Description

The Technical Perfumer
Math and Safety with Chris Rusak

Independent perfumer Chris Rusak presents a class covering necessary basics for a safe DIY lab and a technically proficient perfumery practice.

Often ignored in our quest for the next beautiful blend, skillful use of scales and simple math provide the backbone for a thriving and long-standing creative practice with scent. More importantly, they are crucial to the proper dilution of raw perfume materials and preparation of final blends. This class is an indispensable first step for practicing perfumers and all lovers of scent, and will be repeated, periodically.

In this class, Chris will go over scale terminology and types (from inexpensive postal scales to analytic balances) relative to the DIY perfumer. He will cover different mathematical routes to dilution, thinking in ratios, and how to easily make the switch from working in drops to grams.

This will lead us to a discussion of published safe usage limits, particularly how to interpret and accurately use data from sources like IFRA, The Good Scents Company, and Tisserand & Young.

Finally, he will cover the harmful effects of improper use, particularly how oxidation or carelessness can lead to permanent sensitization. We will review the *long* list of natural materials into which antioxidants should be added and then be refrigerated, as well as other chemicals that should be kept in low dilution.

Finally, we will apply this knowledge and practice properly antioxidizing our materials, as a group.
