Latest Patents

Zastrow holds a patent for "Cosmetic compositions with agglomerated substrates." This invention relates to cosmetic compositions that contain agglomerates with specific particle sizes. The compositions are characterized by the inclusion of spherical non-porous SiO2 particles with a particle size ranging from 0.05 to 1.5 micrometers, along with other inorganic particle-shaped materials that possess a spherical structure. The spherical SiO2 and other inorganic materials form defined agglomerates with a particle size between 0.06 micrometers and 5 micrometers. The proportion of these agglomerates in the cosmetic composition varies from 0.1 to 30% by weight. The aggregate-containing dispersions are produced by introducing the spherical SiO2 step by step under special conditions. Formulations created with these aggregates are noted for their particularly stable and high sunscreen factors.
