A method of evaluating inhibitory effect on damp-dry malodor, containing the steps of: bringing microorganisms which produce damp-dry malodor-causing substances and a test substance into contact with each other in the presence of a sebaceous dirt component; detecting expression of at least one kind of gene selected from a fatty acid desaturase gene and a &#x3b2; oxidation-related enzyme gene derived from the microorganisms; and thereby evaluating a damp-dry malodor inhibitory function of the test substance based on a change in expression amount of the at least one kind of gene.

Method of evaluating inhibitory effect on damp-dry malodor

A method of screening a damp-dry malodor inhibitor, containing the steps of: bringing microorganisms having a 4-methyl-3-hexenoic acid production capacity into contact with a test substance in the presence of a sebaceous dirt component, detecting the production of a damp-dry malodor-causing substance by the microorganisms, and thereby selecting a test substance having a damp-dry malodor inhibitory function; and a method of evaluating a damp-dry malodor inhibitor, containing the steps of: bringing microorganisms having a 4-methyl-3-hexenoic acid production capacity into contact with a test substance in the presence of a sebaceous dirt component, detecting the production of a damp-dry malodor-causing substance by the microorganisms, and thereby evaluating the damp-dry malodor inhibitory function of the test substance.

Method of screening for a damp-dry malodor inhibitor and method of evaluating damp-dry malodor inhibitor by microbial production of 4-methyl-3-hexenoic acid

The present invention provides a wrinkle-removing composition capable of removing wrinkles in fiber products without deteriorating the texture, even if heat treatment such as ironing and steam pressing is not carried out. The present relates to a wrinkle-removing composition containing an alkylene oxide adduct (a) represented by a specific general formula (1) or a general formula (2) or (3), as well as a method of removing wrinkles in fiber products, which includes applying the wrinkle-removing composition onto fiber products.

Wrinkle-removing composition

The invention provides a soil release agent and a detergent composition blended therewith. The invention relates to a crosslinked product obtained by reacting a compound having 2 to 32 hydroxyl groups, such as triethanol amine, with a compound having at least two functional groups reacting with hydroxyl groups, such as (poly)ethylene glycol diglycidyl ether, a soil release agent containing the crosslinked product, and a detergent composition containing the soil release agent.

Detergent composition

A powdered detergent composition comprising a nonionic surfactant as the main surfactant, which comprises (a) a polyoxyethylene alkyl ether, wherein the alkyl group has 10 to 20 carbon atoms on the average and the average molar number of ethylene oxide added is 5 to 15, in an amount of 12 to 35% by weight based on the total weight of the composition, (b) a lipolytic enzyme in such an amount that the lipolytic activity per gram of component (a) would be 0.1 to 500 LU, (c) an anionic surfactant in an amount of 1.0 to 7.0% by weight based on the total weight of the composition and (d) an alkaline material in an amount of 5 to 35% by weight based on the total weight of the composition, and of which a 0.1% by weight aqueous solution has a pH exceeding 9.0, is excellent in detergency on oily soils such as subum soil.
