Gallic acid vehiculized through liposomes or mixed micelles in biofunctional textiles

Abstract

Liposomes and mixed micelles were used to vehiculize gallic acid, as antioxidant, when applied to different textiles designed to be in contact with the skin as biofunctional textiles. Foulard and bath exhaustion processes were assayed without the use of a binder. Liposomes with the antioxidant encapsulated were applied to cotton, polyamide, polyester, acrylic, and wool, using bath exhaustion and the pad-dry process. Higher absorption was obtained with bath exhaustion than with the pad-dry process for all fabrics. Liposome application to the different textiles showed an adequate substantivity for most fibers. However, the high desorption of most synthetic acrylic and polyester fibers confirmed the preferential application of cotton and polyamide as cosmetic biofunctional textiles. Moreover, this study showed that polyamide always presented high substantivity for the two phospholipid structures and also for the antioxidant.
