Lubricating compositions, in the form of oil-in-water emulsions, are based on a siloxane and do not release hydrogen and are particularly suited for the lubrication of internal surfaces of uncured or unvulcanized envelopes useful for the manufacture of rubber pneumatic or semi-pneumatic tires for vehicles, as well as for vulcanization bladders useful for the shaping and vulcanizing of pneumatic or semi-pneumatic tires.
