Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a liquid detergent composition for hard surfaces.

[0002]

2. Description of the Related Art Conventional detergent compositions are used properly depending on the type and degree of stains. In other words, for hand stains and unmodified oil stains that are relatively lightly soiled, the surfactant / solvent-based detergent was deteriorated by the effects of heat around the kitchen, sunlight, oxygen in the air, etc. Surfactants / solvents / alkaline cleaners for greasy stains, etc. Surfactants / solvents / sequestrant cleaners for metal soap in the bathroom, especially calcium salts of fatty acids. Is becoming mainstream.

Further, the solvent which is the main component of the detergent is generally an alkylene glycol alkyl ether type solvent obtained by adding ethylene oxide and / or propylene oxide to a lower alcohol in view of detergency and damage to the substrate. However, various cleaning agents have been proposed which have a certain level of detergency by using these solvents (see, for example, Japanese Examined Patent Publication (Kokoku) No. 50-40126).
54-158408, JP-A-61-151300, JP-B-55
-9036, JP-A 1-2221497), on the other hand, because of the solvent odor, it causes discomfort during use, or requires masking by the addition of a fragrance component or the like, even if a fragrance component is added. The scent has not reached a satisfactory level.

Further, JP-A-2-132199 proposes to improve the odor by limiting the content of isomers in a specific solvent (propylene oxide adduct of lower alcohol), but the solvent is completely used. It has not reached the point where the odor is suppressed.

Further, the alkylene glycol alkyl ether type solvent has a high reactivity with respect to air oxidation, and it has been difficult to stably store it in the compounded composition without using an antioxidant.

[0006]

As a result of further intensive studies, the inventors of the present invention have found that 3-methyl-1,3-butanediol and / or 3-methyl-1,3-butanediol can be used as a solvent in a cleaning composition for hard surfaces.
