Abstract: Silicone-containing cartridges having a plunger at one end thereof are effectively sealed against moisture penetration by introducing a silicone oil composition having a viscosity of from 5000 mPa·s to 100,000 mPa·s between the walls of the plunger and the interior surface of the cartridge wall.
