    Abstract: The present disclosure relates to thermoplastic compositions, methods of making thermoplastic compositions, and articles made from thermoplastic compositions. The disclosed compositions comprise a polycarbonate polymer, a triacylglyceride release agent, and a monoacylglyceride release agent. In an embodiment, the thermoplastic composition comprises: greater than 90 weight percent based on the total weight of the composition of a melt polycarbonate polymer; a triacylglyceride release agent; and a monoacylglyceride release agent. The total amount of triacylglyceride release agent and the monoacylglyceride release agent is 0.01 to 0.5 weight percent based on the total weight of the composition.
