Abstract

The present invention relates to a nanoencapsulated temperature regulating agent which presents a nanoencapsulated temperature regulating agent (ARTN/NTRA) that aggregates, in a same nanostructure, an organic material capable of undergoing melting by absorbing heat, or solidification by releasing heat, and IR radiation screening nanoparticles, a colloidal oxide capable of reflecting the infrared radiation which causes surfaces exposed to a heat source to heat up. The NTRA produced may be either in the form of a colloidal dispersion in an aqueous medium or in the form of nanoparticles, if the aqueous dispersion of the NTRAs is subjected to any drying process such as spray-drying, fluidized-bed drying, filtration, lyophilization, centrifugation, inter alia. The association of temperature regulating mechanisms and the fact that the NTRA is on a nanometric scale imparts greater efficiency for heat transfer processes and surface-covering power, guaranteeing greater reflection of infrared radiation. By virtue of its versatility and different forms of presentation, this NTRA makes it possible to obtain different types of products for use in the cosmetics, pharmaceuticals, medical equipment, prostheses, textiles, paints, coatings, composites, packaging, civil engineering, electrical or electronic equipment, automobile and paper-making industries.
