Zusammenfassung:	Internal mold release systems that include an internal mold release agent that includes any one of fatty acids, fatty acid esters and metal carboxylates, and employ a poly(dimethylsiloxane) surfactant with the following formula: (CH3)3Si-O-[(CH3)2Si-O-]n-[CH3-Si(R)-O-]m-Si(CH3)3 wherein, R=-(CH2)3-O-[EO]x-R'; R' is H; C1 to C20 alkyl; or C6 to C25 aryl; x is a number from greater than 1 up to about 24; m is a number from 1 to about 25; and n is a number from 0 to about 100. Isocyanate compositions, isocyanate reactive compositions and polyurethane reaction systems that employ the surfactant also are disclosed.
