PROBLEM TO BE SOLVED: To obtain a compound which exhibits a high thickening effect, has a good feeling of use when used in a cosmetic or toiletries and is excellent in viscosity enhancement and emulsion stability. SOLUTION: The disilane compound is prepared by combining an alkoxysilyl group to both ends of a mono- or polyaminoacid having a structure (1) (wherein, R<SP>1</SP>, R<SP>2</SP>and R<SP>3</SP>are each H, a 1-22C alkyl or the like; n is a number of 1-10,000) via a divalent hydrocarbon group which may contain a heteroatom. A polymer obtained by condensing the disilane compound in the presence or nonpresence of an alkoxysilane after hydrolysis, a viscosity enhancer comprising the polymer and a cosmetic containing the viscosity enhancer are also provided.
