Description

  The present invention relates to a liquid detergent composition.

  In recent years, with the increase in environmental awareness and saving consciousness, the remaining hot water of a bath is frequently used as washing water for washing. In the remaining hot water of the bath, various microorganisms such as human origin and soil origin exist. In some countries and regions where water supply is poor, foreign substances such as microorganisms and organic matter may be mixed in the tap water. When water containing a large amount of such microorganisms is used for washing, the microorganisms adhere to the clothing and generate a unique odor, or the microorganisms attached to the clothing grow while the laundry is being dried and produce an odor. There is a problem.

  As a method for suppressing the adhesion of microorganisms in washing water to an object to be washed, Patent Document 1 proposes a bleaching composition containing hydrogen peroxide, a surfactant, a chelating agent, and a cationic polymer. According to the bleaching composition of Patent Document 1, the microorganisms are prevented from adhering to the article to be washed, and are excellent in storage stability.

  This invention is made | formed in view of the said situation, and it aims at the liquid detergent composition which can suppress that microorganisms adhere to a laundry, and was excellent in external appearance stability.

  The present inventors have intensively studied and found that the above problem can be solved by combining a specific antibacterial agent and a specific organic solvent.
