It solves the problems, such as: a kind of composition is provided, wherein the high-temperature stability of oil-in-water emulsion, the raising thickened with hydrophobically modified poly(ether-urethane) composition, and also gluey unique contact is kept.SOLUTION: the present invention provides a kind of elastic gel composition and is characterized in that entering oil in water emulsion containing hydrophobically modified poly(ether-urethane) with whose average grain diameter of mist of oil mist pearl is 150 nanometers or smaller. Elastic gel composition be it is transparent or translucent, have gluey elastic tactility, have excellent viscosity stability, at high temperature, the pedestal suitable for cosmetics. With hydrophobically modified poly(ether-urethane), copolymer (PEG-240/decyltetradeceth-20/HDI) is particularly preferred.In selected attached drawing: attached drawing 1COPYRIGHT:(C) 2016, JPO& INPIT
