Pell Wall Perfumes: Soft-floral, fresh, jasmine, slight spice
Arctander has quite a bit to say about the material: “very mild oily-herbaceous and somewhat floral odor, reminiscent of many types of natural flowers, but mostly of jasmin, gardenia and tuberose. introduces jasmin-like floralness when accompanied by more volatile chemicals of floral character. blends excellently and assists in fixation of the fragrance (aca is quite tenacious) … aca is very susceptible to oxidation unless properly treated with an antioxidant (conventionally added by most manufacturers). old or oxidized aca has [an] objectionable, rancid-fatty odor. lower grades of aca may show by-odor of benzaldehyde, heptaldehyde or amyl nonenal, sometimes called di-heptenal.
