PROBLEM TO BE SOLVED: To provide a method for dissolving polysaccharide by which the polysaccharide can be used without any problem even when it can not be used with alcohols such as ethanol, propylene glycol and glycerol, low molecular weight surfactants, fatty acids, readily water-soluble sugar or a general-purpose water-soluble polymer compound such as polyethylene oxide and which has high dissolution promoting effect, and to provide a thickener composition which contains a polysaccharide as a main component and can be used without any problem even when salts coexist or pH change occurs or even when thickened under an acidic or alkaline condition and can readily be dissolved in an aqueous medium. SOLUTION: This method for dissolving polysaccharide comprises dissolving polysaccharide into an aqueous medium in the presence of polyamino acids. This thickener composition consists essentially of polysaccharide having thickening action when dissolved in the aqueous medium and contains the polysaccharide and polyamino acids.
