Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning composition for hard surfaces, which is excellent in foaming power and has good rinsing properties after cleaning, and is particularly suitable as a bathroom cleaning composition.

[0002]

2. Description of the Related Art Basic properties required for a cleaning agent for a hard surface, particularly for a bathroom or a bathtub, include cleaning power and foaming power. It is generally said that there is no relationship between detergency and foaming power, but consumers often judge detergency based on the disappearance of foam during cleaning, and are rich in palatability. They tend to prefer soft foaming. In addition, since a detergent such as a detergent for a house is inevitable to touch the skin such as a hand at the time of washing, a mild detergent for the skin has been conventionally required.

[0003] The stains in the bathroom are mainly caused by metal soaps, especially calcium salts of fatty acids. Conventionally, a neutral detergent containing a surfactant, a water-soluble solvent and a chelating agent has been reported as a detergent for removing such debris.

For example, Japanese Patent Application Laid-Open No. 53-35710 discloses a pH of 4 containing an anionic surfactant, a nonionic surfactant, an alkylene glycol alkyl ether solvent, and a chelating agent such as citric acid or ethylenediaminetetraacetate. Although a bath cleaner of 0.5 to 7.5 is described, the cleaning power and foaming power were not sufficient, and the rinsing properties after cleaning were not satisfactory.

[0005] Detergent compositions containing a phosphate-based surfactant having a mild skin irritant as a main cleaning base material have also been reported. However, foaming power is formed by forming insoluble salts with divalent metal ions. Led to a decline.

Japanese Patent Application Laid-Open No. Sho 62-124194 discloses a method of adding a tertiary amine oxide for the purpose of enhancing foaming power and detergency. However, while foaming is enhanced, rinsing properties are reduced. There was a disadvantage that it was bad.

[0007]

On the other hand, a sugar derivative, alkylglycoside, is a low-irritant surfactant and, despite being a nonionic surfactant, itself forms a stable foam. Furthermore, it is known that it acts as a foam stabilizer for other anionic surfactants, and has recently been receiving attention.

For example, JP-A-58-104625 describes a foaming surfactant composition containing an alkyl glycoside and an anionic surfactant. Other hard surface cleaners containing alkyl glycosides include JP-A-62-501570 and JP-A-2-64.
198, JP-A-2-247299, JP-A-3-56596, JP-A-3-166298, JP-A-5-98288, JP-A-5-9828

17085, JP-A-7-216399, JP-A-8-120293, and the like.

However, these cleaning compositions have a foaming power,
Although they have excellent detergency, they all have the drawback of poor foam removal.

[0010]

The inventors of the present invention have conducted intensive studies and as a result, have found that by using a glycoside having a hydrocarbon group having a specific average carbon number as a substituent, it has excellent detergency and foaming power, In addition, a cleaning composition for hard surfaces with improved rinsing properties due to good foam removal has been developed.

That is, according to the present invention, as the component (A), the following general formula (1)

R ¹ O— (Z) _n (1) (wherein, R ¹ represents a hydrocarbon group having an average carbon number of 8.0 to 9.5, and Z is a residue derived from a reducing sugar. Where n is Z
