Vector diseases treatment based on intermediate complexion using textile substrates
2019Co-Authors: Maesta Bezerra Fabricio, Silva, Tais Larissa, Lis Arias, Manuel JoséAbstract:The most efficient insect repellents are DEET (N, N-diethhyl-meta-toluamide) from synthetic origin and citronella essential oil from natural origin. However, there are other products that can also be used as insect repellents from synthetic origin, such as: DEPA (N, N-Diethyl Phenylacetamide), Icaridin, IR3535 and Permethrin and, of natural origin: Carapa guianesis, Atemisia vulgaris, Ocimim., basilicum, Cinnamomum camphora, Corymbia citriodora, Eucalyptus sp, Cymbopogon, Mentha pulegium. All those products are the basis of most commercial repellents; however the action of these repellents is of short duration, due to the volatility of the chemical compounds of these products and, therefore they offer an uncontrolled release. The authors have shown that there would be an alternative to control their release based on the complexation of the active principle (the repellent oil). Thus, the repellent will have its prolonged effect and will protect the user longer. The active principle can be used in repellent products, applied to the skin via spray or can be used on textiles. According to Lis Arias et al. when used in textiles, these products become biofunctional, enabling the delivery of assets for Cosmetotextiles applications. Due to its specific response, biofunctional textiles are especially useful when the textile comes into close contact with the skin. Thus, these products can be used as insect repellents, reducing the number of infections caused by these vectorsPostprint (published version

Cosmetotextiles with gallic acid: skin reservoir effect
'Hindawi Limited', 2013Co-Authors: Marti Gelabert Meritxell, Alonso Merino Cristina, Martínez Rodríguez Vanessa, Lis Arias, Manuel José, De La Maza, Alfons, Parra Juez, José Luis, Coderch Negra LuisaAbstract:The antioxidant gallic acid (GA) has been incorporated into cotton (CO) and polyamide (PA) through two different vehicles, that is, liposomes and mixed micelles, and their respective absorption/desorption processes have been studied. Moreover, in vitro percutaneous absorption tests of different Cosmetotextiles have been performed to demonstrate antioxidant penetration within the layers of the skin. When GA was embedded into the Cosmetotextiles, it always promoted a reservoir effect that was much more marked than that observed for polyamide. Similar penetration was observed in the textiles treated with GA in mixed micelles or liposomes in such compartments of the skin as the stratum corneum, epidermis, and even the dermis. GA was detected in receptor fluid only when CO was treated with MM. This methodology may be usef ul in verifying how encapsulate ed substances incorporated into textile materials penetrate human skin. Indeed, such materials can be considered strategic delivery systems that release a given active compound into the skin at specific dosesPostprint (published version

Applications of chitosan in food, pharmaceuticals, medicine, cosmetics, agriculture, textiles, pulp and paper, biotechnology, and environmental chemistry
Environmental Chemistry Letters, 2019Co-Authors: Nadia Morin-crini, Giangiacomo Torri, Eric Lichtfouse, Gregorio CriniAbstract:Chitosan is a biopolymer obtained from chitin, one of the most abundant and renewable materials on Earth. Chitin is a primary component of cell walls in fungi, the exoskeletons of arthropods such as crustaceans, e.g., crabs, lobsters and shrimps, and insects, the radulae of molluscs, cephalopod beaks, and the scales of fish and lissamphibians. The discovery of chitin in 1811 is attributed to Henri Braconnot while the history of chitosan dates back to 1859 with the work of Charles Rouget. The name of chitosan was, however, introduced in 1894 by Felix Hoppe-Seyler. Chitosan has attracted major scientific and industrial interests from the late 1970s due to its particular macromolecular structure, biocompatibility, biodegradability and other intrinsic functional properties. Chitosan and derivatives have practical applications in the food industry, agriculture, pharmacy, medicine, cosmetology, textile and paper industries, and in chemistry. In recent years, chitosan has also received much attention in dentistry, ophthalmology, biomedicine and bioimaging, hygiene and personal care, veterinary medicine, packaging industry, agrochemistry, aquaculture, functional textiles and Cosmetotextiles, catalysis, chromatography, beverage industry, photography, wastewater treatment and sludge dewatering, and biotechnology. Nutraceuticals and cosmeceuticals are actually growing markets, and therapeutic and biomedical products should be the next markets in the development of chitosan. Chitosan is also the object of numerous fundamental studies. In this review, we highlight a selection of works on chitosan applications published over the past two decades.

Nutraceuticals and cosmeceuticals are actually growing markets, and therapeutic and biomedical products should be the next markets in the development of chitosan. Chitosan is also the object of numerous fundamental studies. An indication of the widespread exploitation and constantly growing importance of this biopolymer is the total of over 58,625 scientific articles published between 2000 and 2017. In this chapter, after a description of chitosan fundamentals, we highlight selected works on chitosan applications published over the last two decades.

fragrance allergens possibilities of their identification in components of Cosmetotextiles
IEEE International Symposium on Medical Measurements and Applications, 2016Co-Authors: Emilia Adamowicz, Magdalena Sikora, Radoslaw Bonikowski, Michal FrydrysiakAbstract:Fragrances and essential oils are often microencapsulated and applied on textiles designed for elders, both as compounds of cosmetics and as fragrances e.g. in aromatherapy. However in the aromatic compositions there may be compounds with allergenic activity. Possibility of identification potential fragrance allergens which may be applied on textiles in microcapsules is presented in this article.

Isolation of α-tocopherol from cotton Cosmetotextiles
Fibres and Textiles in Eastern Europe, 2019Co-Authors: Iva Matijević, Tanja Pušić, Sandra BischofAbstract:Cotton fabrics were treated with cosmetic substances based on α-tocopherol and cyclodextrine. Isolation of α-tocopherol from cotton Cosmetotextiles was performed using three different techniques: stirring, Soxhlet and microwave extraction. High performance liquid chromatography (HPLC) was optimised and applied for the quantification of α-tocopherols in the isolates. The results revealed that all techniques are applicable for the isolation of α-tocopherol from cotton Cosmetotextiles. The HPLC method proved to be the most convenient for the quantification of α-tocopherol from cotton fabrics.

Application of HPLC for Quantification of α-Tocopherol in Cosmeto-cotton
2016Co-Authors: Sandra Bischof, Tanja Pušić, Iva MatijevićAbstract:Cosmetotextiles proved to be very interesting source of active ingredient to be used as wellbeing products. The major issue of this treatment is durability of the product. Its lifetime is tried to be prolonged using different application methods (pad-roll, exhaustion, printing or coating) and active ingrediants. α-tocopherol was used in this study for its strong antioxidant property, capable to enhance anti aging effects of cotton products. Up to now, major concern has been dedicated to qualitative determination of active ingrediants while the aim of this study was to establish reliable analytical method for the quantification purposes. The mechanism of slow release of active ingredience is a necessary demand which can be monitored only through precise qualitative methods, such as HPLC. This method proved to be convenient indirect method enabling quantification of previously isolated α-tocopherol from cotton fabric using extraction with methanol.

Determination of α-Tocopherol in Cosmetotextiles – UV/Vis Spectrophotometric Method
2015Co-Authors: Iva Matijević, Sandra Bischof, Ana Sutlović, Tanja PušićAbstract:Tocopherol is a chemical name for vitamin E that belongs to the group of amphipathic and lipidsoluble compounds that are easily oxidized when subjected to heat, light and alkaline conditions. Vitamin E can be used as active cosmetic substance for functionalization of textiles, acting as anti-ageing agent through gradual release on the skin. The paper deals with Cosmetotextiles, carriers of Vitamin E contained in a suspension of cyclodextrine - a- tocopherol complex, applied in finishing. Research is focused on development of a method for determination of a- tocopherol in a form metal organic chelate complex using UV/VIS spectrophotometry.
