TARGETED DELIVERY OF ACTIVES:Cationic Nanoparticles for use in Hair and Skin Products

The inclusion of, for example, sunscreens in hair care products is of great interest because of the potential to reduce damage such as drying and loss of elasticity and also to reduce the fading of color-treated or bleached hair. For a variety of reasons traditional methods of incorporation of UV filters have often proved difficult and, at best, unsatisfactory; the need for additional solubilizers, changes in residual feel, rinse out, incomplete wetting and poor affinity have all been noted and observed.
