Zusammenfassung:To provide a crosslinking agent capable of manufacturing a surfactant having excellent emulsification performance to various kinds of oil agents and securing salt tolerance, acid resistance and base resistance.SOLUTION: There is provided a crosslinking agent of organopolysiloxane consisting of an alkyloxirane derivative represented by the formula 1, in which Mand Mcalculated from gel permeation chromatogram satisfy a relationship of the formula 2. RO-(AO)n-R(1), wherein AO is an oxyalkylene group having 3 carbon atoms, n is the number of 25 or more, and Ris an alkenyl group having 3 to 5 carbon atoms. 0.35≤M/M≤0.75 (2), wherein Mis distance between a point O and a point P, and Mis distance between a point Q and a point P, when length of perpendicular from a maximum point K with maximum refraction index on the gel permeation chromatogram to a base line is L, a point with earlier elution time of 2 points on chromatogram having refraction index strength of L/2 is the point O, and a point with later elution time is the point Q, and an intersection point of a linear line G connecting the point O and the point Q and the perpendicular drawn to the base line is P.SELECTED DRAWING: Figure 1 【課題】各種の油剤に対し優れた乳化性能を持ち、耐塩性、耐酸性および耐塩基性を確保する界面活性剤を調製可能な架橋剤の提供。【解決手段】式1で表されるアルキルオキシラン誘導体からなるオルガノポリシロキサンの架橋剤であって、ゲル浸透クロマトグラムから算出されるMHとMLとが式2の関係を満足する。R1O−(AO)n−R1・・(1)(AOは炭素数3のオキシアルキレン基、nは25以上の数、R1は炭素数3〜5のアルケニル基)、0.35≦ML/MH≦0.75・・(2)(ゲル浸透クロマトグラム上の屈折率強度が最大の極大点Kからベースラインへの垂線の長さをLとし、屈折率強度がL/2となるクロマトグラム上の2点のうち溶出時間が早い方を点Oとし、溶出時間が遅い方を点Qとし、点Oと点Qを結ぶ直線Gと点Kからベースラインへ引いた垂線との交点をPとした時、点Oと点Pの距離をMHとし、点Qと点Pの距離をMLとする。)【選択図】図1
