Description

TECHNICAL FIELD The present invention relates to a hard surface liquid detergent composition suitable for cleaning and sterilizing hard surfaces such as living rooms, kitchens, and toilets.

[Conventional technology and its problems]

The dirt attached to the hard surface can be easily removed by washing immediately after that, but in general, it is left as it is for a long time and stubbornly deposited on the hard surface. Therefore, strong agents such as alkaline agents, acids, sodium hypochlorite, sodium percarbonate or solvents are used as components other than surfactants in hard surface liquid detergents.

When cleaning a hard surface, it is natural to remove dirt, but consideration must be given to prevent damage to the material. Examples of material damage include metal corrosion, yellowing of wood such as white wood, damage to concrete and tile joints, and countermeasures for each have been proposed.

Compared to these materials, plastics are generally considered to have chemical resistance and are used for various purposes. However, it has been found that cleaning certain plastic products with hard surface liquid detergents can cause damage. Examples of such plastic products include an electric light umbrella made of polycarbonate, ABS (acrylonitrile /
For example, a toilet seat made of butadiene / styrene copolymer) may be used. If these surfaces are washed with a hard surface liquid detergent, cracks may occur.

It is presumed that the cause is due to a surfactant which is an alkylene oxide addition type surfactant and a solvent which is a monohydric alcohol or a polyhydric alcohol and a derivative thereof.

[Means for Solving the Problems]

As a result of earnest studies to solve the above problems, the present inventors have found that a detergent containing a specific surfactant and two specific solvents damages plastics forming various products around the house. In addition, the present invention has been completed by finding out that it does not have an excellent detergency and imparts a desirable gloss to the surface to be coated.

That is, the present invention provides (a) one or more surfactants selected from alkyl glycosides, sugar fatty acid esters and amphoteric surfactants.
0.01-5% by weight (b) Monohydric alcohol with a vapor pressure of 2 mm Hg (20 ° C) or higher,
One or two selected from polyhydric alcohols and their derivatives
1 or more solvent 1 to 30% by weight (c) 0.5 to 15% by weight of one or more solvent selected from ethylene glycol, propylene glycol, butanediol, glycerin and hexylene glycol The present invention provides a hard surface liquid detergent composition for residential use.

Among the components (a) used in the hard surface liquid cleaning composition for homes of the present invention, alkyl glycosides and sugar fatty acid esters are sugar-based nonionic surfactants and have a polymerization degree of 1-10.
It is obtained by a dehydration condensation reaction of the monosaccharide, polysaccharide or complex sugar of 1) with an alcohol or fatty acid having 8 to 18 carbon atoms. Examples of the sugar-based nonionic surfactant include the following general formula (I) or (II) R-O- (Z) _x (I). Compounds represented by are particularly preferred.

In each of the above formulas, R is an alkyl group or alkenyl group having 8 to 18 carbon atoms, preferably 10 to 14 carbon atoms, R ₁ is an alkyl group or alkenyl group having 7 to 17 carbon atoms, preferably 9 to 13 carbon atoms, and x is 1 to 1. 1
0, preferably 1.2 to 3, and n is 1 to 2. Z is a sugar residue, and examples of monosaccharides include glucose, fructose, galactose, xylose, mannose, lyxose, arabinose, and the like, and mixtures thereof. Examples thereof include sucrose, nigerose, solanose, raffinose, gentianose, melezitose, and mixtures thereof. Among these, preferred sugar raw materials are glucose and fructose as monosaccharides because of their availability and low cost.
Above sugar, maltose and sucrose.

Examples of the other component (a), the amphoteric surfactant, include amphoteric surfactants of amino acid type, amide amino acid type, carbobetaine type, sulfobetaine type and the like. In particular, from the viewpoint of solution stability, the following general formula (III) or (IV) The betaine type surfactant represented by

In the above formulas, R ₂ is an alkyl or alkenyl group having 8 to 18 carbon atoms, preferably 10 to 14 carbon atoms, R ₃ is an alkyl group having 1 to 4 carbon atoms, preferably 1 to 2 carbon atoms, and R ₄ is 1 carbon atom. 6 shows an alkylene group or a hydroxyalkylene group.

Among the surfactants, the alkylene oxide addition type surfactant damages the plastic surface. Therefore, the surfactant as the component (a) used in the present invention is limited to those having no polyoxyalkylene group.

The component (a) is 0.01 to 5% by weight in the composition, preferably 0.1.
1 to 5% by weight is blended. If the content of the component (a) is less than 0.01% by weight, a sufficient cleaning effect cannot be obtained, and the amount is 5% by weight.
If it exceeds the range, problems such as wiping and stickiness will occur.

In the present invention, two kinds of solvents are used, one of which is a monohydric alcohol having a vapor pressure of 2 mm Hg (20 ° C.) or more,
One or two selected from polyhydric alcohols and their derivatives
1 to 30% by weight of one or more solvents (b) are used. Specific examples of the monohydric alcohol include ethyl alcohol, isopropyl alcohol, propanol, butanol, secondary butanol, and tertiary butanol. Examples of the polyhydric alcohol and its derivative include ethylene glycol monomethyl ether, propylene glycol monomethyl ether, and dimethyl. Examples thereof include glycol, diethyl glycol, dimethyldiglycol and the like. Vapor pressure is 2mm Hg (20
Polycarbonate or AB for solvents above
It does not damage S plastics. Further, these solvents are useful for removing oily stains derived from sebum stains and the like adhering to the hard surface. If the content of the component (b) is less than 1% by weight, it does not have a sufficient effect on the removal of oily stains, and if it is more than 30% by weight, the risk of odor, stickiness and fire may be reduced. There is a problem in terms. The component (b) is preferably blended in the range of 5 to 15% by weight.

Furthermore, as the other solvent, 0.5 to 15% by weight of one or more solvents (c) selected from ethylene glycol, propylene glycol, butanediol, glycerin and hexylene glycol are blended. Vapor pressure is 2 mm H
Many solvents below g (20 ° C) damage plastics. The solvent used as component (c) has a vapor pressure of 1 mm.
It is Hg (20 ℃) or less and non-volatile, but it has been proved that it does not damage plastics such as polycarbonate or ABS. Further, the function of these solvents is to improve the polishing effect of the hard surface, but if the compounding amount of the component (c) is less than 0.5% by weight, the polishing effect is not sufficient, and if it is 15% by weight or more. The amount of residue on the surface increases, causing problems such as wiping and stickiness. The component (c) is preferably blended in the range of 2 to 10% by weight.

The composition of the present invention is balanced by adding water to the above components (a) to (c). In addition to the above, an alkaline agent, a dispersant, an acid, an inorganic agent used in ordinary detergents may be used as necessary. Alternatively, it is possible to appropriately add optional components such as an organic builder, a fragrance, a dye, a pigment, a preservative and a bactericide.
