PROBLEM TO BE SOLVED: To provide a composition in which high temperature stability of an oil-in-water emulsion composition thickened with hydrophobically modified polyether urethane is improved, and moreover jelly-like unique touch is maintained.SOLUTION: The invention provides an elastic gel composition characterized by containing hydrophobically modified polyether urethane into an oil-in-water emulsion with an oil droplet whose average particle diameter is 150 nm or less. The elastic gel composition is transparent or translucent, has a jelly-like elastic touch, is excellent in viscosity stability at high temperature, and is suitable for a cosmetic base. As the hydrophobically modified polyether urethane, a copolymer (PEG-240/decyltetradeceth-20/HDI) is particularly preferable.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】 疎水変性ポリエーテルウレタンで増粘した水中油型乳化組成物の高温安定性を改善し、なおかつぷるぷるとした独特の触感が保持された組成物を提供する。【解決手段】 平均粒径150nm以下の油滴を有する水中油型乳化物に、疎水変性ポリエーテルウレタンを含有せしめたことを特徴とする弾力ジェル状組成物。当該弾力ジェル状組成物は透明又は半透明でぷるぷるとした弾力のある触感を有し、高温での粘度安定性にも優れており、化粧料基剤に適している。前記疎水変性ポリエーテルウレタンとしては、(PEG-240/デシルテトラデセス-20/HDI)コポリマーが特に好ましい。【選択図】図1
