A compound having an effect of thickening the flowable organic substance to a desired viscosity, and having an effect of uniformly stabilizing the composition of the composition containing the flowable organic substance by thickening the flowable organic substance, Provided are a thickening stabilizer containing a compound, a thickening stabilizing composition containing the thickening stabilizer and a flowable organic substance, and a method for producing the same. The thickening stabilizer of the present invention has the following formula (1) (R2-HNOC) 4-n-R1- (CONH-R3) n (1) (wherein R1 represents four hydrogen atoms from the structural formula of butane. R2 and R3 are different from each other and are aliphatic hydrocarbon groups having 4 or more carbon atoms, n is an integer of 1 to 3).流動性有機物質を所望の粘度に増粘する効果を有し、流動性有機物質を含有する組成物の組成を流動性有機物質を増粘することにより均一に安定化する効果を有する化合物、前記化合物を含む増粘安定剤、前記増粘安定剤と流動性有機物質を含む増粘安定化組成物、及びその製造方法を提供する。 本発明の増粘安定剤は、下記式(1) (R2-HNOC)4-n-R1-(CONH-R3)n (1)(式中、R1はブタンの構造式から4個の水素原子を除いた基であり、R2、R3は互いに異なって、炭素数4以上の脂肪族炭化水素基である。nは1~3の整数である)で表される化合物を含む。
