Abstract:
A method for cleaning elastomeric articles comprising contacting the elastomeric article with at least one supercritical fluid under conditions and for a time sufficient to remove the phthalates and/or polynuclear aromatic hydrocarbons (PAHs) contained therein. Elastomeric articles having a reduced phthalte and/or PAH content prepared by the above method are also claimed. Such elastomeric articles having reduced phthalate contents can be utilized as gaskets, valves, seats, flaps or plugs in metered dose delivery devices such as aerosols for demanding medicinal and pharmaceutical uses.
