Abstract: A disinfectant detergent composition containing a food or food additive as a main component is provided. The disinfectant detergent composition contains the following components (a), (b), and (c). The sum [a+b] of the component (a) content and the component (b) content of the composition ranges from 0.1% to 30% by mass, the mass ratio [a/b] of the component (a) to the component (b) ranges from 1/2 to 4/1, and the component (c) content of the composition ranges from 60% to 99.5% by mass. (a) polyoxyethylene sorbitan monolaurate (b) a fatty acid glyceride in which the number of carbon atoms of its acyl group ranges from 8 to 12, the monoglyceride content of the component (b) being 85% by mass or more, the mass fraction of 1-monoglyceride relative to the total amount of monoglycerides being in the range of 0.9 to 1.0 (c) water and/or ethanol.

Abstract: Provided is a defoamer for fermentation which has excellent dispersibility in water and forms neither a precipitate nor oil droplets when the dispersion is heated, and which is highly effective in defoaming fermentation media. This defoamer contains a reaction product obtained by mixing a fat or oil having an iodine value of 40 to 130 with glycerin or like in a molar ratio of from 3/2 to 1/2 to obtain a mixture, causing 4 to 17 mol of propylene oxide to add to 1 mol of the mixture, and then causing 20 to 40 mol of ethylene oxide and 70 to 110 mol of propylene oxide to block-wise add thereto in this order, the reaction product having an ethylene oxide/propylene oxide molar ratio of from 1/4 to 2/5.
