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 liquid deodorant having a high deodorizing effect and lasting ability to a fabric or fabrics. That is, the present invention provides a liquid deodorant which comprises 80 to 99% by weight of water and has a pH of 7.5 to 9.5 at 25&#xb0; C., 1000 ml of which deodorant may be adjusted to pH 10 at 25&#xb0; C. with 10 to 200 ml of 0.1 N aqueous NaOH and may be adjusted to pH 7 at 25&#xb0; C. with 20 to 500 ml of 0.1 N aqueous HSO.
