Abstract
A composition comprising the following components: a) at least one propylene/ethylene interpolymer or at least one propylene/alpha-olefin interpolymer, each interpolymer comprising the following properties: i) a melting point, Tm, from 60° C. to 85° C., ii) a viscosity (177° C.) from 3,000 cP to 30,000 cP; b) at least one wax; c) at least one oil; and wherein the composition has a weight ratio component b to component c from 0.30 to 4.0.
