The organosilicon resin obtained is well dispersible in a resin premix containing a polyol, a blowing agent, a catalyst and a foam stabilizer, and also is highly hydrophobic and low reactive. Hence, the resin premix containing the organosilicon resin has good storage stability. Accordingly, this resin premix need not be agitated when used and also can provide polyurethane foams having superior properties such as dimensional stability.
