Resumen:
In recent years, textile materials have been found with applications in the cosmetics field. On contact with human body and skin, cosmetic textiles are designed to transfer an active substance for cosmetic purposes. The principle is achieved by simply imparting the cosmetic and pharmaceutical ingredients into the fabric of clothing so that with the natural movement of the body, the skin is slowly freshened and revitalised. Microencapsulation technology is an effective technique used to control the release properties of active ingredients that prolong the functionality of cosmetic textiles. This technique consists of the coating of the cosmetic by a material that in most cases is polymeric in nature. Natural polymers such as polysaccharides have attracted great attention as coating materials because of their lack of toxicity, biodegradability and wide availability. Among all polysaccharides, alginate has become an excellent candidate for hydrogel microparticles formation. Due to its anionic nature, alginate can easily be structured in microgels through ionic cross-linking with divalent cations, such as calcium ions (ionic gelation). The present work shows the preparation of alginate microgels loaded with Undaria Pinnatifida algae powder obtained by air extrusion method. Undaria Pinnatifida is an alga originally from Asian southwestern that in the last decades spread through Argentinian coast. Despite its invasive nature, these algae offer benefits like the improvement of skin and hair, among others. Thus, the treatment of the garments with algae powder-loaded microgels allows developing a functional textile of low-cost production
