Skatolene is a diluted form of skatole (3-methylindole), presenting an intensely animalic, fecal-floral character in isolation. At high dilution it opens into narcotic white-floral facets reminiscent of jasmine and orange blossom, with a warm, mothball-like indolic undertone. Overdosed it turns barnyard and unpleasant; used in trace it lends carnal depth to florals.AI · claude-opus-4-7

According to the origin of the material, Skatolene shows great variation in odor. The type of Skatolene showing an intensely warm-animal odor, tenacious, sweet and uniform, with no traces of fecal note, is generally a preferred one.
Skatolene is used for floral complexes, where animal notes are tolerable or desirable. It should add warmth, depth, tenacity and life to such fragrance types, and Skatolene can be used quite freely, in amounts often surprising the perfumer unless he is very familiar with the effect of Skatolene. Concentrations up to several percent of this material can be experienced without any offensive effect. In Gardenia, Narcisse, certain types of Rose, and in heavy exotic or Oriental fragrance types, the title material can add very attractive character.
Produced by condensation of Skatole with Hydroxycitronellal in the molecular proportion of 2:1.
