Description

Description: FIELD OF THE INVENTION The present invention relates to a hard surface cleaning composition comprising an alkylglycoside surfactant as a main cleaning base, in which the cleaned hard surface has good drying properties.

[Conventional technology]

Conventionally, anionic surfactants such as alkylbenzene sulfonate, α-olefin sulfonate, alkyl sulfate, paraffin sulfonate, and ethoxylated alkyl ether sulfate have been used as main surfactants in hard surface detergents such as tableware. Was. Above all, sodium alkylbenzenesulfonate has been widely used as a base having excellent cleaning performance, but it has a strong degreasing power from the skin and has a drawback that hand roughness easily occurs. For this reason, recently, polyoxyethylene alkyl ether sulfate, which is less irritating to the skin, is used as a main cleaning base, and an auxiliary surfactant such as an alkyl tertiary amine oxide or a higher fatty acid diethanolamide is used in combination to wash the skin. While further improving the power and foaming power,
Detergents with a milder effect on the skin have become the mainstream.

However, although the action of the detergent containing an anionic surfactant as a main ingredient on the skin has been milder than before, it has not yet reached a satisfactory level. is there.

Since anionic surfactants have a dissociating group, they are essentially easily adsorbed on the skin, and there is a limit in improving skin irritation. Therefore, if a nonionic surfactant having a hydrophilic group of an alkylene oxide represented by a polyoxyethylene alkyl ether or the like as a hydrophilic group is used as a main agent, a nonionic surfactant having a low adsorptivity to the skin is certainly used. Although it has low adsorptivity to water, its foaming power is remarkably inferior to that of a detergent composition containing an anionic surfactant as a main component, and thus it cannot satisfy the requirements as a detergent.

On the other hand, alkyl glycosides, which are sugar derivative surfactants, are low-irritant surfactants, and even though they are nonionic surfactants, they themselves produce stable foams. Is attracting attention.

As the detergent using an alkyl glycooxide, for example, JP-A-58-104625 discloses a highly foamable multi-particulate detergent composition containing an alkyl glycoside and an anionic surfactant, JP-A-58-132094 discloses a detergent composition for clothing having a high detergency containing an alkyl glycoside and a nonionic surfactant, and JP-A-62-74999 discloses an alkyl glycoside and an anionic surfactant. A liquid cleaning composition for hand-washing dishes, which contains an agent and a fatty acid alkanolamide, is mild and has excellent foaming and cleaning power.

[Problems to be solved by the invention]

However, the above-mentioned conventional cleaning agent containing an alkyl glycoside as a main cleaning base has a drawback that when applied to a hard surface, the drying property after cleaning is not very good. And, if the drying property of the tableware or the like is poor, the bacteria easily propagate, which is not preferable in terms of hygiene.

[Means for solving the problem]

Under such circumstances, the present inventors have conducted intensive studies to improve the drying property of a cleaning composition containing a hypoallergenic alkyl glycoside as a main cleaning base on hard surfaces, and as a result, If the amount of the nonionic surfactant is reduced and the terpene hydrocarbon is mixed in a small amount,
The present inventors have found that the above objects can be achieved, and have completed the present invention.

That is, the present invention relates to the following components (a), (b) and (c), (a) 15 to 40% by weight of an alkyl glycoside surfactant, and (b) a nonionic surfactant other than (a). Wherein (a) / (b) is from 100/1 to 100/9, and (c) 0.01 to 3% by weight of a terpene hydrocarbon selected from monoterpenes and sesquiterpenes. It provides a composition.

In the present invention, the component (a) used as the main surfactant is represented by the following general formula (1).

R ₁ (OR ₂ ) _x G _y (I) (wherein, R ₁ represents a linear or branched alkyl, alkenyl, or alkylphenyl group having 8 to 18 carbon atoms;
R ₂ represents an alkylene group having 2 to 4 carbon atoms;
It is a residue derived from a reducing sugar having ６6, and x has an average value of 0-5. (y has an average value of 1 to 10) (I) In the formula (I), x has an average value of 0 to 5, and this value controls water solubility and crystallinity. That is, the higher x is, the higher the water solubility tends to be and the lower the crystallinity. Preferred values of x are 0-2. When y has an average greater than 1, that is, when it contains a surfactant represented by the general formula (I) having two or more sugar chains as a hydrophilic group, the sugar chain binding mode is 1-2, 1 -3, 1-4, 1-6 bond, and α
It is possible to include any mixture having-, [beta] -pyranoside, or furinoside linkages and their mixed modes of attachment. Further, y is 1 to 10, and a preferable average value is about 1.0 to 3.0. Further, R ₁ is a linear or branched alkyl group having 8 to 18 carbon atoms, an alkenyl group or an alkylphenyl group, and preferably 10 to 14 carbon atoms from the viewpoint of solubility, foaming property, and detergency. It is. R ₂ is an alkylene group having 2 to 4 carbon atoms, and a preferable value is 2 to 3 in view of water solubility and the like. Further, the structure of G is determined by a monosaccharide or two or more raw materials. Examples of the G raw material include glucose, galactose, xylose, mannose, lyxose, arabinose, and mixtures thereof in monosaccharides. For sugars or more, maltose, xylobiose, isomaltose, cellobiose, gentibiose, lactose, sucrose, nigerose, turanose, raffinose, gentianose, melezitose, and mixtures thereof. Among these, glucose and fructose are preferred as monosaccharide raw materials, and maltose and sucrose are preferred as disaccharide or higher saccharides in terms of availability and low cost.

Component (a) is generally added to the composition in an amount of 15 to 40% by weight, preferably 20 to 30% by weight.

Examples of the component (b) include higher fatty acid esters of polyhydric alcohols such as polyoxyethylene alkyl ether, polyoxyethylene alkyl phenyl ether, higher fatty acid alkanolamide, alkylamine oxide, glycerin, pentaerythritol, sorbitol and sorbitan, and alkyl. Nonionic surfactants known in the art such as glyceryl ether can be used.
Particularly preferred activator of component (b) is glycerin monofatty acid ester. This activator has the effect of further increasing the foaming power of the alkyl glycoside. The component (b) needs to be blended in the composition so that (a) / (b) is 100/1 to 100/9 by weight, and if less than this, the foaming power is inferior. If the amount is more than the above range, the drying property deteriorates, and the object of the present invention is not achieved.

The component (c) used in the present invention includes a monoterpene-based hydrocarbon or a sesquiterpene-based hydrocarbon contained in a vegetable aromatic oil. As monoterpene hydrocarbons, D- or L- contained in orange oil, lemon oil and the like are included.
Α- or β-pinene contained in limonene, terpin oil and the like, α-terpineol contained in pine oil and the like, and the like. Examples of sesquiterpene hydrocarbons include fern oil, clover oil, and cananga oil. Examples thereof include calooffylene, cedrene, and the like. Each terpene-based hydrocarbon selected from monoterpenes and sesquiterpenes can be used alone as the component (c) of the present invention, or two or more can be used in combination, and furthermore, orange oil, Terpine oil and pine oil can be incorporated into the composition of the present invention as they are. The amount of component (c) is 0.1% of the detergent composition.
It is in the range of 01 to 3% by weight, preferably 0.1 to 2% by weight. If the amount is less than 0.01% by weight, the intended improvement of the drying property is insufficient, while if it is 3% by weight, the coloring property and the low-temperature stability of the detergent composition are unfavorably deteriorated.

By further adding a small amount of an anionic surfactant to the composition of the present invention, a composition that produces a soft, fine, creamy foam can be obtained. Up to 9 parts by weight, preferably 1 to 9 parts by weight, of the anionic surfactant is added to 100 parts by weight of the alkyl glycoside. If the amount exceeds 9 parts by weight, the drying property and the roughening property tend to be impaired, which is not preferable.

Examples of the anionic surfactant include, for example, alkyl benzene sulfonate, polyoxyethylene alkyl ether sulfate, α-olefin sulfonate, paraffin sulfonate, higher fatty acid salt, and polyoxyethylene alkyl ether carboxylate. Activators known in the art are included. Among them, polyoxyethylene alkyl ether sulfate and polyoxyethylene alkyl ether carboxylate are preferred from the viewpoint of skin irritation.

The cleaning composition of the present invention, in addition to the above components, ethanol, hydrotropes such as ethylene glycol,
Any commonly used optional ingredients such as fragrances, dyes, preservatives, fungicides, humectants and the like can be added.
