PERFUME COMPOSITIONS

A perfume composition which includes components that have synergistic odor properties is prepared by selecting a first inactive component in a first mixture which has the most similar odor character to a candidate active component; selecting a second inactive component in the first mixture which has the least similar odor character to the candidate active component; preparing a second mixture in which the first inactive component is replaced by an iso-intense concentration of the candidate active component and the second inactive component is replaced by a known active from the same odor class as the second inactive component; and then selecting the candidate active component for preparing the composition if the odor of the second mixture is significantly more intense than that of the first mixture, in which case the candidate active component is considered to show resilient activity.
