Mixtures comprising inorganic compounds and effect substances, where the inorganic compounds are present as agglomerates and these agglomerates have a specific surface area greater than 10 m 2 /g, a particle size of from 1 to 20 μm, a loss on ignition of from 1 to 20%, a carbon content of from 0.1 to 5%, a methanol wettability of from 10 to 90% and an effect substance absorption of from 100 g to 4000 g, based on 100 g of inorganic compound. These mixtures comprise, as effect substances, UV absorbers, stabilizers, antioxidants, flame retardants, antifogging additives, lubricants, plasticizers, antistats, dyes, optical brighteners, IR dyes or biocides. The inorganic compounds are selected from the group of oxides, carbonates, hydrogencarbonates, phosphates, sulfates, hydroxides, silicates and sulfides and comprise alkali metal, alkaline earth metal or transition metals. The mixtures are used in the processing or the use of inanimate organic materials, for example in the protection of inanimate organic materials such as polymers or coatings against oxidative, thermal or light-induced degradation or the effect of UV radiation. |
