Abstract: The present invention provides a composition for controlling the formation of a biofilm composed of microorganisms and microorganism-producing substances or for promoting the removal of a biofilm in various fields and a method for suppressing biofilm formation and for removing a biofilm. The present invention provides a composition of a biofilm control agent containing the following component (A) and component (B): (A) one or more compounds selected from the group consisting of compounds represented by the general formulas (1), (2), (3), and (4): (wherein R1, R2, R3, and R5 each represent an alkyl group or alkenyl group; R4 represents a hydrogen atom or an alkyl group; EO represents an ethyleneoxy group; p represents an integer of 0 to 3; and m and n each represent the average number of added moles and m+n represents a number of 0 to 15); and (B) an enzyme.

Abstract: The present invention provides a virucide composition and/or sporicide composition having a high virucidal effect and sporicidal effect and being excellent in safety and workability. That is, the present invention provides a virucide composition and/or sporicide composition comprising (a) an inorganic peroxide, (b) tetraacetylethylenediamine and (c) at least one selected from a salt of an alkaline metal salt with an inorganic acid and a salt of an alkaline earth metal with an inorganic acid in a specific ratio.

Abstract: A frying oil or fat composition employable for producing fried foodstuffs having satisfactory crisp and well acceptable moderate oily or fatty taste comprises not more than 4.0 weight % of an emulsifier dissolved in an oil or a fat. The emulsifier should be chosen to make the oil or fat composition show an interfacial tension of not more than 7 mN/m at 80.degree. C., 3 sec. after the time when the oil or fat composition is mixed with water to form an interface between a phase of the oil or fat and an aqueous phase. A frying oil or fat composition containing a sugar fatty acid ester of a specifically selected composition, or a combination of a sugar fatty acid ester and a polyglycerol fatty acid ester and/or a diglyceride is also employable for the same purpose.
