## Abstract

The present invention provides a fouling-resistant composition which comprises an elastomer and a component comprising sterol(s) and/or sterol derivative(s), wherein the component is selected from acylated lanolin, alkoxylated lanolin, or lanolin oil, or a composition comprising at least 20 weight % of one or more sterol(s), at least 20 weight % of one or more C1-C12 sterol ester(s), or at least 20 weight % of alkoxylated sterol(s), wherein weight % is the percentage of the sterol or sterol derivative to the total weight of the component.
