No, they do not. All chemicals including those used to enhance textile fibres are subject to the European chemicals legislation (REACH) or even stricter regulations such as the biocides' regulation and have to be approved in this context. Textiles for normal use in everyday life have neither to be tested nor approved by anyone.

In sunscreens, two different filter types are used for UV protection: (1) chemical UV filters, which absorb the UV radiation and emit it with less energy; (2) mineral UV filters, which reflect the UV radiation thereby protecting the skin. Both types may be present in their nano-form. The first group contains two organic compounds, MBBT and TBPT, as insoluble nanoparticles which absorb UV-light. Titanium dioxide (chem. TiO2) and zinc oxide (chem. ZnO) belong to the group of mineral UV filters. These nanoscaled materials do not form any white film on the skin surface, which is preferred for aesthetic reasons by many users. In addition, especially the mineral UV filters in nanoform allow the realisation of very high sun protection factors (SPF factors >30) without having to use additional chemical components.

The main motivation to use nanomaterials in pesticide formulations is to increase the solubility of the active ingredient. This has some advantages over conventional pesticides with regard to controlled and targeted release, protection against the degradation of the active ingredient, and hence overall an increased efficiency for pest control. Collectively, this enables reducing the dose of the active ingredient while achieving comparable or even better performance of the product.

Yes, the EU Biocidal Products Regulation has specific provisions for nanomaterials. These provisions apply for active and non-active substances. If a nanoform of an already approved pesticide shall be used, the nanoproduct needs extra approval by submitting a dossier with all required data.

Liposome © natros / fotolia.comLiposome © natros / fotolia.comAlthough liposomes are often referred to as nanoparticles, they differ from classical nanoparticles in both, their structure and in their stability . Liposomes are therefore not nanoparticles in a narrower sense.

Nanoparticles are made of solid materials. Liposomes can be between a few nanometers to even 10 microns in size. They consist of certain lipids (so-called phospholipids, e.g from soy) together with other materials and form a hollow sphere consisting of one or more double membranes (bilayers - see Fig. 1, liposome with a double membrane). They are filled with water and require a water-loving environment. Their bilayers are water-loving on the outside and also inside of the hollow sphere. They are usually less stable than nanoparticles.

The encapsulation system "nanosome" is very similar to the liposomes. Nanosomes, however, possess only a single lipid monolayer. The name refers to their extremely small size. The name Nanosome is mainly used in cosmetics.
