    摘要: Formulation comprising hydrophobicized particles of silicon dioxide, mineral oil and one or more emulsifiers, where the hydrophobicized silicon dioxide is a fumed silicon dioxide, possesses a BET surface area of 200 to 300 m2/g, has on the surface of the particles O—Si—(CnH2n+1)3 groups, where n is 1 to 3 and where the (CnH2n+1) units are alike or different, has a carbon content of 1.5% to 5% by weight, based on the hydrophobic silicon dioxide, and is present in the formulation with a fraction of 0.05% to 5% by weight.
