13. A perfume composition according to claim 1, wherein: the sum of the concentrations of perfume ingredients selected from GROUP 3, GROUP 4 and GROUP 5, each perfume ingredient counted only once in the sum, is between 5 and 60 wt. %.

14. A perfume composition according to claim 1, wherein: the sum of the concentrations of perfume ingredients selected from GROUP 5 is between 0.1 wt % and 30 wt %,

Description

EXAMPLE 1

[0105] 0.24% by weight of the following perfumery ingredients are dissolved in 99.76% of a mixture comprising 76.4% ethanol, 10% tri-ethyl citrate and 3.6% water; and 10 microliters of this solution are placed on a etched glass plates having a etched surface of 0.41.8 cm.sup.2 and a total surface of 0.52 cm.sup.2 and let to evaporate for 4 hours at a temperature of 32 C.+/2 C. Each plate is then inserted in the device as described above and submitted to aforementioned flow and room convection conditions, whereas the optimal measurement conditions for said room were obtained by setting the air flow at 20 ml/min. The odour intensity is then measured at the outlet of the channel at least 5 trained panellists and reported in Table 1. All ingredients are detected within 60 seconds in average. The scores obtained by panellists deemed anosmic to a particular ingredient are removed.

[0106] Ingredients having an average intensity higher than 7 were given a Score Class A; ingredients having an average intensity ranging from 6 to 7 were given a Score Class B; ingredients having an average intensity ranging from 5 to 6 were given a Score Class C; ingredients having an average intensity ranging from 3 to 5 were given a Score Class D and ingredients having an average intensity ranging from 1 to 3 were given a Score Class E and the ingredients having an average intensity lower than 1 were given a Score Class F.

EXAMPLE 2

[0107] The formulations of a series of perfumes are reported in Table 2 as illustrative but not limitative examples. The sums of the concentrations of the ingredients in each GROUP are also reported in Table 2. The intensity at distance was measured according to the following procedures: 10 microliters of a solution of 10% perfume in solvent comprising 96% ethanol and 4% water (hydro-alcoholic solution)_are placed on a etched glass plates having a etched surface of 0.41.8 cm.sup.2 and a total surface of 0.52 cm.sup.2 and let to evaporate for 4 hours at a temperature of of 32 C.+/2 C. Each plate is then inserted in the device as described above and submitted to aforementioned flow and room convection conditions, whereas the optimal measurement conditions for said room were obtained by setting the air flow at 20 ml/min. The odour intensity is then measured at the outlet of the channel (i.e. 2 m away from the source) by at least 5 trained panellists and reported in Table 2. Perfumes having an average intensity higher than 7 were given a score +++; perfumes having an average intensity ranging from 4 to 7 were given a score ++; perfumes having an average intensity ranging from 1 to 4 were given a score +and perfumes having substantially no trail (i.e. an average intensity lower than 1) were given a score .

[0108] Perfumes C, D, E, F, G and H were detected within 60 seconds in average and found to produce a coherent, fast developing and prolonged olfactory impact at a distance of 2 m, whereas the coherence and development speed were found to increase with increasing intensity. On the contrary, perfumes A and B, which were not obeying the composition rules according to the present invention were found to produce an incoherent olfactory impact at a distance of 2 m, i.e. the perfume did not reach a maximum odour intensity could not be recognized by the skilled panellists within the time frame of the measurement. Only perfumes C, D, E, F, G and H can be considered as having coherent, fast developing and prolonged olfactory impact at a distance from the compositions' source, when submitted to convection flows
