Liquid composition with improved storage stability, which contains an amide group-containing guanidine derivative or/and a salt thereof

A liquid composition containing an amide group-containing guanidine derivative represented by the following general formula (1):

• 4
• (in the formula, R1 and R2 are independently hydrogen atom or a linear or branched alkyl group or alkenyl group with one to 4 carbon atoms and may be the same or different;
• R3 represents a linear or branched alkyl group or alkenyl group with one to 22 carbon atoms;
• and X represents a linear or branched alkylene group or alkenylene group with one to 10 carbon atoms) or/and a salt thereof (component A) and at least one (component B) selected from the group consisting of an inorganic salt, an organic acid salt, a nonionic surfactant and an ampholytic surfactant with an action to suppress the generation of the precipitate of the component A, in which the blend ratio of the component A/component B (in weight ratio)=1/0.5 to 1/20.
