Resum:
Textile detergent and softener industries have been incorporating in their processes the perfume microencapsulation technology. This technology allows the protection of the fragrance before and during industrial processes, as well as in the product storage. Moreover, it protects the perfume during the laundry and it provides a long-lasting fragrance release after the drying and storage of fabrics. However, certain current industrial microcapsules present a number of drawbacks such as low material stability, low perfume encapsulation capacity and, in addition, with the industrial encapsulation method presently used it is extremely complicated to encapsulate polar perfumes. With the aim to solve these problems, polysulfone (PSf) capsules containing vanillin and prepared by phase inversion precipitation technique have been proposed. In this investigation, PSf/Vanillin capsules have been successfully prepared and characterized. Results show that PSf/Vanillin capsules may ensure a high perfume encapsulation capacity, a long lasting fragrance release, a good material stability, and an optimal perfume protection. Because all these qualities, PSf/Vanillin capsules have the potential to be used not only in detergents and softeners but also in other textile products.
