Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laundry method and a detergent composition, and more particularly, it suppresses the activity of bacteria causing causative odors and decomposes and removes stains that cause the malodour to metabolize the bacteria. Thus, the present invention relates to a laundry method and a detergent composition capable of preventing the generation of a bad odor even when laundry clothes are dried at room temperature and high humidity for a long time, such as indoor drying.

[0002]

2. Description of the Related Art Conventionally, the problems to be solved by the invention
In detergent compositions, it is known that an antibacterial effect and a bactericidal effect are imparted by blending an antibacterial component (antibacterial agent, bleaching agent and bleach activator). In addition, it has been proposed to suppress a bad odor derived from bacteria (for example, the odor of freshly dried laundry) by antibacterial effects and bactericidal effects, for example, JP-A-9-19.
Japanese Patent No. 4899 proposes to suppress a bad odor generated by the decomposition of sebum stains and the like by a nonionic activator, an oil absorbing carrier and an antibacterial agent.

However, in the case of the above-mentioned proposal, although the growth of bacteria can be suppressed by the antibacterial action and the bactericidal action, it is not possible to remove the dirt which is a nutrient source of the bacteria, and therefore a bad odor is easily generated. There has been a demand for a technique capable of sufficiently suppressing a bad odor even when dried indoors.

The present invention has been made in view of the above circumstances, and inhibits the activity of bacteria even when laundry clothes are dried for a long time at room temperature and high humidity such as indoor drying. An object of the present invention is to provide a laundry method and a detergent composition capable of effectively preventing the generation of a bad odor.
