White flakes.

Warm, honeyed, metallic, sweaty odour, resembling rose with an animalic (castoreum) and jasmine-like nuance. Dry, medicinal, sweeter on dilution.

In traces it could lend interesting effects in jasmin, rose, cuir type fragrances, tobacco or animal accords.

This product doesn’t resemble civet on its own (in my opinion) but, as suggested in some works, I understand its use in civet imitation bases. Somehow dirty (not fecal): it is waxy, fatty, sweet and slightly acrid (tanned leather, vinegar, feet-like odour) and it could bring texture and roundness to the stronger skatole or indole.

What is surprising about this material is that it lasts forever on paper or tissue. According to S. Arctander’s Perfume and Flavor Chemicals, phenylacetic acid is

[…] one of the most tenacious odorants of all known and used perfumery materials. It will outlast Vanillin on a ‘blotter test’ and a 5% solution of Phenylacetic acid may last more than 3 years on a blotter […]
