Abstract
Disclosed is a method for removing fatty oil from a surface containing the fatty oil comprising the steps of applying to the surface containing the fatty oil a composition comprising a sol-gel derived material, the sol-gel derived material including a plurality of alkylsiloxy substituents and the sol-gel derived material obtained from(a) at least one first alkoxysilane precursor having the formula: (R′O)3—Si—(CH2)n—Ar—(CH2)m—Si—(OR′)3 (1) where n and m are individually an integer from 1 to 8, Ar is a single-, fused-, or poly-aromatic ring, and each R′ is independently a C1 to C5 alkyl group and (b) optionally, at least one second precursor having the formula:where x is 1, 2, 3 or 4; y is 0, 1, 2, 3; z is 0, 1; the total of x+y+z is 4; each R is independently an organic functional group; each an R′ is independently a C1 to C5 alkyl group and R″ is an organic bridging group and then moving the composition from the surface to remove the fatty oil.
