Abstract

The evaluation of the performance of new products to be released on the market is essential to measure its acceptability by consumers. In this work, the performance of an added-value product, microencapsulated perfumes applied on textiles for man suits, was predicted and evaluated. The odor intensity and character of the perfume ingredients was measured by headspace gas chromatography after dry cleaning and abrasion tests on textiles impregnated with microcapsules. The evaporation and diffusion of the fragrances in the encapsulated perfume was assessed. For this type of application, limonene has shown a better performance in the perfume mixture, being the dominant note over time and distance. © 2011 American Institute of Chemical Engineers AIChE J, 58: 1939–1950, 2012
