Abstract
Abstract A reusable permeable dispenser for dispensing solid or semi-solid fabric conditioning agent which can be attached to a machine dryer drum or tumbles loosely in the dryer, comprising a flexible permeable container comprising a composition of a quarternary ammonium anti-static agent, a polyalkylene oxide compound, and silicone dioxide which has a substantially constant release rate regardless of dryer operator temperature.
