PHOTONIC PARTICLES; COMPOSITIONS CONTAINING THEM; METHODS OF PHOTOPROTECTING VARIOUS MATERIALS

WIPO Patent Application WO/2011/045741

A3

The present invention provides photonic particles (1) with a mean size in the range 1 μm to 500 μm, in particular in the range 1 μm to 300 μm, comprising a diffracting arrangement of hollow nanoparticles (10), as well as compositions containing a dispersion of said particles. The present invention also provides a method of photo protecting human keratins material against solar UV radiation. The present invention also provides methods of photo protecting industrial materials such as paints, inks, coatings, materials manufactured from polymers, or fibrous materials such as textiles, papers, or organic or mineral glasses.
