Patent ID: 8426478

Claim:
A formulation consisting of hydrophobicized particles of silicon dioxide, mineral oil and one or more emulsifiers, wherein the hydrophobicized particles of silicon dioxide are fumed, possesses a BET surface area of 200 to 300 m 2 /g, have on the surface of the particles O—Si—(C n H 2n+1 ) 3 groups, where n is 1 to 3 and where the (C n H 2n+1 ) units are alike or different, have a carbon content of 1.5% to 5% by weight, based on the hydrophobicized particles of silicon dioxide, and are present in the formulation in an amount of from 0.05% to 5% by weight, based on the total weight of the formulation, wherein the formulation comprises: 40% to 90% by weight, based on the total weight of the formulation, of the mineral oil, and 2% to 25% by weight, based on the total weight of the formulation, of the emulsifier.
