Description
Summary:The design of fragrances for laundry products which deliver a prolonged odor intensity at key consumer touch points is an ongoing challenge in the fragrance industry. Current fragrance development practices are based on the combination of perfumery expertise (eg creation of classic and modern odor themes such as Chypre or Fougère) with technical know‐how (eg chemical–physical properties of fragrance ingredients). However, due to the complexity of such multi‐component mixtures this process still requires a significant number of trial and error cycles throughout the fragrance development process to achieve the desired odor intensity and character requirements. To improve the efficiency of the fragrance development process, we have combined simple, high throughput analytical methods with psychophysical models, to predict the intensity and character of fragrances at three key consumer touch points for laundry products. The predicted results have shown a good agreement with experimental ones, making this approach useful in the early research phase for defining the structure/backbone of highly performing fragrance themes. Fragrance design for consumer laundry products involves different physical and chemical interactions amongst multi‐component mixtures of chemicals. In this study, we validated a simple and fast process model to predict the intensity and character of the fragrance at multiple sensorial stages.
