A case study of product engineering: Performance of microencapsulated perfumes on textile applications

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

A review of the preparation and application of flavour and essential oils microcapsules based on complex coacervation technology

“…Microcapsules can provide a strong adhesive force and a more intimate contact with fabrics due to their large surface area that can not only form a uniform and continuous coating on the surface of the fabrics, but also fix in the spacing of the fibres . As for textiles, the major interests in microencapsulation by complex coacervation are durable fragrances, medicine and antimicrobial essential oils …”

A rapid approach to optimize the design of fragrances for fabric care products

“…In this stage, the process for fragrance release can be described by a function of the physical–chemical properties of the ingredients, their corresponding concentration and molecular interactions occurring at ingredient–ingredient and ingredient‐bulk base levels. Such complex model represents a multi‐nonlinear vapor–liquid–liquid equilibria process (see for simple systems). Following on the fabric care cycle, the wet/damp stage starts during the washing cycle and continues when taking the laundry out of the washing machine.…”

Sustained‐release properties of cotton fabrics impregnated with nanotuberose fragrance

“…prepared orange oil microcapsules coated with chitosan via a spray‐drying method; the microcapsules had a mean diameter of less than 20 μm, and the encapsulation efficiency of the orange oil was greater than 90%. In particular, the application of capsules containing fragrances and essential oils in textiles has been focused recent years . Yang et al .…”
