Abstract PROBLEM TO BE SOLVED: To provide a novel detergent having antiseptic, antifungal, and algal control effects added to a reaction thermostat using water as a medium in scientific instruments, particularly to a thermostat in an automatic analyzer. SOLUTION: A quaternary ammonium salt represented by the following general formula [1] (Wherein R 1 to R 4 each independently represents an alkyl group, provided that at least one of R 1 to R 4 is an alkyl group having 8 to 18 carbon atoms, and at least one is carbon. the number is 1 to 3 lower alkyl groups .X - represents an anion derived from a carboxylic acid having 2 or more carbon atoms). Alternatively, a detergent for a thermostatic bath containing a preservative having an amphoteric surface active ability and a surfactant, and a method for cleaning the thermostatic bath characterized by adding the detergent to the thermostatic bath.
