Abstract
A new concept of perfumery ternary diagrams (PTDs), based on an analogy between perfume pyramid structure and engineering ternary diagrams, was developed in this work. These diagrams allow a fast evaluation of the odour value in the headspace for all possible combinations of a perfume liquid mixture with three fragrant components and one solvent. A theoretical prediction of the PTD was made, based on perfumery binary lines (PBLs) and perfumery ternary points (PTPs). As an example, this methodology was applied to the system: benzaldehyde–2-phenylethanol–eugenol in ethanol. The effect of ethanol content in the ternary system was also studied.
