Abstract: A water-free composition for treating the walls of a die for original shaping or reshaping contains up to 30% of a polyolefin and/or paraffin wax and at least 70% of oil, where the oil is a silicone oil, a synthetic oil, a vegetable oil, a mineral oil, or a blend of several such oils. To produce a water-free composition according to the invention, one or more waxes are mixed with the oil or oils and any additives desired until a homogeneous mixture is obtained. The water-free release/lubricating agents according to the invention are used especially to treat the walls of a die for shaping or reshaping.
