<p>A less dusty, more stable and more easily handleable protector against UV light than previously is obtained by supplying it in the form of solid particles having a mean diameter of at minimum 10 νm and containing, dispersed in 90-20 parts by weight of wax, 10-80 parts by weight of a pigment which reduces the penetration UV light and is made up of metal oxide particles of a mean primary particle diameter smaller than 0.150 νm.</p> |
