A cyclic siloxane compound, composition, method, and an article including the siloxane, wherein the cyclic siloxane has the following Formula (I): wherein: each R1 and R2 is independently a (C1-C4)alkyl; each L1 and L2 is independently a single bond, an alkylene, or an alkylene bonded to a group selected from oxy, thio, carbonyl, -NH-, and combinations thereof; each R3 is independently a linear (C14-C100)alkyl; each R4 is independently a (C1-C30)alkyl, a (C2-C30)heteroalkyl having at least one oxygen, sulfur, or -NH- group, or a (C1-C30)alkyl substituted with a fluoro, thiol, isocyanato, cyanato, hydroxyl, glycidoxy, or epoxy group; with the proviso that L1, L2, and R4 are selected such that each Si atom is directly bonded to an alkylene or an alkyl; m is an integer of at least 2; n is an integer of 0 or above; m + n is an integer of at least 3; and the cyclic siloxane compound is a solid at 25°C.
