Nanomateriales en limpiadores de superficies duras

Minerva Fernández, David Amantia, Jaume Josa i Pons, Laurent Aubouy
Cada vez es mas común encontrar la presencia de nanomateriales en los productos de gran consumo, ayudando a mejorar las propiedades deseadas en los mismos, así como incrementando su versatilidad y eficacia. En este artículo se presenta un resumen de los limpiadores que contienen nanomateriales y que se encuentran hoy en día en el mercado, junto con las propiedades que están ayudando a conseguir. Por otra parte, se analiza la literatura existente sobre la posible toxicidad con el fin de responder a las controversias actuales sobre estos nuevos materiales. Actualmente ya existen algunas normativas al respecto en algunos ámbitos, aunque la falta de legislación también refleja la falta de conocimiento sobre su posible toxicidad en los seres vivos y el medio ambiente.

Interaction of Surfactants on new textiles products

Roshan Paul, Miquel Osset, Minerva Fernández, Lorenzo Bautista, Jordi Mota, Laia Crespo, Mirko Faccini, Antonio Machín, Carles
Sol-gel and plasma technologies have been used to develop 3 new or improved properties on textiles: reduced transparency, improved dye uptake, and highly hydrophobic textiles. Interaction, of surfactants on these 3 new textile products has been evaluated. It was observed that current detergent formulations are able to maintain the textile opacity and improve whiteness degree from initial non-treated fabrics, especially with color care special detergents. However, UV absorption values are not correctly preserved by current laundry detergents. On the other hand, color care special detergents preserve the original dye fastness on plasma pre-treated textiles. Finally, it has been shown that plasma operational conditions to obtain hydrophobic nanocoatings are more critical than types of detergents used in laundry processes. Oxidants, pH, aggregation state, insoluble builders and the presence of dye-transfer inhibitors on detergent formulations have to be optimized to minimize fiber damage and maintain efficacy of textile properties.
