Abstract: Suggested is a method for improving the performance of a fragrance or a fragrance mixture, comprising or consisting of the following steps: (a) providing at least one fragrance capable of being thermos-activated; (b) optionally incorporating said at least one fragrance of step (a) into a cosmetic composition; (c) applying either said at least one fragrance of step (a) or said cosmetic composition of step (b) to human hair; and (d) exposing the hair to thermal treatment, wherein said at least one fragrance is selected from the group consisting of fragrances showing defined boiling points, Log P values and/or diffusivities.

Abstract: Suggested is a device for assessing the sillage of fragrance materials, comprising or consisting of the following parts: (i) an evaluation tube (1) that is open on both ends; (ii) a ventilation system (2); (iii) at least two lockable sniffing ports (3a, 3b . . . ); (iv) a sample port (4); (v) a sample plate (5) and optionally (vi) a sample holder (6) whereby (a) said evaluation tube (1) is aligned horizontally and equipped with said at least two sniffing ports (3) and said sample port (4); (b) the front opening of said evaluation tube (1) is equipped with said ventilation system (2); (c) at least one sniffing port (3a) is located in the front section and at least one sniffing port (2b) is located in the rear section of said evaluation tube (3); (d) said sample port (4) is located within the front section of said evaluation tube (1); and (e) said sample port (4) has a diameter allowing to introduce either the sample plate (5) or the sample holder (6) into the evaluation tube (1).
