PROBLEM TO BE SOLVED: To provide an oil gelling agent which can form a highly stable gel by blending in an oil solution in a small amount and does not need to expose to excessive high temperature in a step of producing an oil gel, and to further provide an oil gel composition containing the oil gelling agent and the oil solution.SOLUTION: There are provided: an oil gelling agent consisting of an alkanol amide derivative represented by the general formula (1)； and an oil gel composition containing the oil gelling agent and the oil solution. [RCO is an acyl group having 16 to 22 carbon atoms containing a hydroxyl group； RCO is a different composition from RCO and is a linear/branched alkylene group having 14 to 22 carbon atoms which may contain an unsaturated bond or a polyalkylene group； X is H or an alkyl group having 1 to 3 carbon atoms, a hydroxyethyl group or a hydroxypropyl group； n is an integer of 1 to 3.]SELECTED DRAWING: None【課題】オイルゲル製造工程で過剰な高温にさらす必要が無く、且つ、油剤に少量配合することで安定性の高いゲルを形成することができる油ゲル化剤、更に該油ゲル化剤と油剤を含有する油ゲル組成物の提供。【解決手段】式（１）で示されるアルカノールアミド誘導体よりなる油ゲル化剤、及び該油ゲル化剤と油剤を含有する油ゲル組成物。〔Ｒ１ＣＯはヒドロキシル基を含有するＣ１６～２２のアシル基；Ｒ２ＣＯはＲ１ＣＯとは異なる組成；不飽和を含有してもよいＣ１４～２２の直鎖／分岐のアルキレン基又はポリオキシアルキレン基；ＸはＨ若しくはＣ１～３のアルキル基又はヒドロキシエチル基ヒドロキシプロピル基；ｎは整数１～３〕【選択図】なし
