Truffle Factor

The odour and uses of Truffle Factor
Using Beta-Androstenol 0.01%. We recommended to using Beta-Androstenol 0.01% in fragrance compounds at a maximum of 0.1 to 1% (w/w) 1 to 10 grams per Kg or Litre of perfume compound. This will ensure that the active Androstenol content does not exceed 1 ppm 1 part-per-million which has been found to be the upper limit at which the pheromones are esthetically acceptable.
The materials used are high purity reconstructions using synthetic sources and no human or animal extracts were used in their production.
Beta-Androstenol is found in truffles, and is offered as an explanation for how pigs locate them deep in the ground. It is endogenous to humans and pigs, behaving as a pheromone and contributing to axillary odor. Androstenol is biosynthesized in the testes, the adrenal glands and the ovaries in humans. In addition, androstenol may be synthesized in the human nasal mucosa from androstenone, and likely also from androstadienol and androstadienone in this area. Due to its ability to cross the blood-brain-barrier, androstenols are likely present in the central nervous system as well. In animals, androstenols have been found to produce anxiolytic-like, antidepressant-like, and anticonvulsant effects. They also been found to modify the behavioral and social responses of humans. It has been proposed that androstenol may be involved in the menstrual synchrony of women. Source Wikipedia.
