We already have information available from a project completed recently reviewing the perfumes currently used in toilet soap bars in Europe. A range of soaps was profiled by the sensory panel and the results were analysed to give a two-dimensional map showing the

relative similarities in odour character of the perfumes tested (Figure 8.5).
Those fragrances that are closest together on the map are most similar in odour character, whilst those that are furthest apart are most different. So, for instance, fragrances A59 and C33 are relatively similar in odour character, while A59 and D28 are quite different. To interpret the map and describe the nature of the differences between the odours, a correlation analysis is carried out. This analysis enables us to identify the characteristics that are most important in distinguishing between the fragrances, and the direction of increasing perception of each of these characteristics is indicated on the map with an arrow. So we can tell, for instance, that A59 is perceived to be far more fruity than D28.
We used a similar type of analysis to look for correlations between the odour character of the fragrances (defined by their position on the map) and results obtained from large-scale market research. The market research attributes found to be directly related to the odour perception of the samples are shown on the map in Figure 8.6, with arrows indicating the direction of increasing perception of each attribute.
The map indicates that the fragrances in the herbal, green and citrus areas are totally inappropriate for fragrance development for this brief: they are perceived by the consumer as functional, cleaning, invigorating and refreshing. Neither is the sweet floral, aldehydic area appropriate as, although it is seen as feminine, it is also perceived as cosmetic

or suitable for everyday care. The area that the perfumer needs to concentrate on is that described as white floral (muguet, jasmin) and fruity (melon, peach), which is perceived to convey the impression of a product that pampers you, and would be used as a once-a-week treat.
