The invention provides a thickener which is excellent in stability in blending and has a high thickening effect and a surfactant composition containing the same, specifically, a thickener consisting of an aliphatic amido ether (1) and a surfactant composition containing the thickener and at least one surfactant, that is, a method for thickening a surfactant with the thickener. (1) In the general formula, R1 is linear or branched alkyl or alkenyl which has 5 to 21 carbon atoms and may be substituted with at least one hydroxyl group; R2 is linear or branched alkyl having 1 to 12 carbon atoms; and R3 is alkylene having 2 to 12 carbon atoms. |
