Arctander writes very extensively about Oakmoss products including that : “Oakmoss products are used extensively in perfumery. They form important parts of the notes in all fougere, chypre or ‘moss’ perfumes, and they are common ingredients in colognes, crepe de Chines, forest notes, new mown hay, pine fragrances, lavender bouquets, Oriental bases, fancy or modern bases, etc. They can lend body and naturalness, rich pleasant undertones and high fixative value in numerous types of floral fragrances as well. Oakmoss products blend well with so many groups of perfume materials that it is hard to confine its use to certain mixtures. The oakmoss product never amounts to many percent of the total weight of a perfume formula (except in very rare cases), but it very often plays a decisive role in the overall performance of the perfume, even when the oakmoss product amounts to a few percent or less by weight.”
He goes on: “One of the most important of all the oakmoss products—if not the most important—is the Absolute of Oakmoss. It is generally prepared by alcohol extraction of the concrete … A special process involves the addition of solid paraffin or ceresin to the melted oak moss concrete. The mixture is chilled, comminuted (by grinding or chopping) and subsequently extracted with ethyl alcohol … the absolute from a benzene extracted concrete [such as this product] is still a solid or semi-solid mass …”
Payan Bertrand describe this material like as: “Mixture of oakmoss extract (Evernia prunastri Ach.) and natural, nature identical and synthetic aromatic products.” in their Technical Data Sheet.
