Pressurised dispensing container

A pressurised dispensing container comprising a container for product to be dispensed, and a valve fixed to the container, wherein the container contains a propellant comprising 1,1-difluoroethane or a derivative thereof and optionally ethanol,

• wherein the valve comprises a valve stem, a valve body and one or more seals, the valve stem being slidable within the valve body, the one or more seals co-operating with the valve stem for regulating discharge of a fluid,
• wherein the valve further comprises a sealing gasket for sealing the valve to the dispensing container,
• wherein the one or more seals is/are formed from (i) an elastomeric composition comprising an ethylene-propylene-diene terpolymer, wherein the ethylene-propylene-diene terpolymer comprises from 40 to 70 wt. % ethylene, from 30 to 50 wt. % propylene, and ENB (ethylidenenorbornene) in an amount of 0.5 to 9 wt. %, and wherein the terpolymer has a Mooney Viscosity (ML 1+4, 125° C.) of from 10 to 90, and
• the sealing gasket is formed from (ii) an elastomeric composition comprising an isobutylene polymer or co-polymer thereof.
