An alkyl group, n is 0 to 5 and R ₄ CO is a saturated or unsaturated linear or branched fatty acid residue having 6 to 22 carbon atoms) Hereinafter, the liquid detergent composition for home use according to the present invention Each component will be described in detail.

The anionic surfactant as the component (A) is not particularly limited as long as it is anionic. Typical examples thereof are as follows, and these are used alone or in combination of two or more kinds. Can be used.

(1) Sulfonate type anionic surfactant Linear or branched alkyl (C _8-22 ) benzene sulfonate Long chain alkyl (C _8-22 ) sulfonate etc. (2) Sulfate type anionic surfactant Agent Long-chain monoalkyl (C _8-22 ) sulfate ester polyoxyethylene (1 to 6 mol) Long-chain alkyl (C
_8-22 ) Ether sulfate ester polyoxyethylene (1 to 6 mol) alkyl (C _8-18 )
Phenyl ether sulfate, etc. (3) Phosphate-based anionic surfactant Long-chain monoalkyl, dialkyl or sesquialkyl (C
_8-22 ) Phosphate Polyoxyethylene (1-6 mol) monoalkyl, dialkyl or sesquialkyl ( _C8-22 ) phosphate etc. (4) Carboxylate type anionic surfactant having 6 to 24 carbon atoms Saturated and / or unsaturated fatty acid salt The counterion (cation) of each of the above-mentioned anionic surfactants is an alkali metal ion, an alkaline earth metal ion, an alkanolamine ion, an ammonium ion, or the like.

The amount of the anionic surfactant as the component (A) to be added to the detergent composition is in the range of 0.1 to 20% by weight, preferably 0.5 to 5% by weight. When the content of the anionic surfactant is less than 0.1% by weight, the action of dispersing and solubilizing dirt is weak, and the interaction with the components (B) and (C) is not sufficient. On the other hand, if the blending amount is more than 20% by weight, no special improvement effect is brought to the detergency and conversely the foam breakage / rinseability deteriorates, which is not preferable.

The amine oxide and amido amine oxide of the component (B) are compounds represented by the above general formulas (I) and (II), respectively, and the _one which can be R _{1 in} the formula is
It is a saturated or unsaturated linear or branched alkyl group having 6 to 22 carbon atoms, preferably 12 to 18 carbon atoms, and R ₂ and R _2
3 is an alkyl group having 1 to 5, preferably 1 or 2 carbon atoms, which may be the same or different and which may be substituted with a hydroxyl group, and n
Is 0 to 5, preferably 1 to 3, and R ₄ CO is a saturated or unsaturated linear or branched fatty acid residue having 6 to 22 carbon atoms, preferably 12 to 18 carbon atoms.

From the standpoints of foamability, adhesiveness, foam-breaking property and skin irritation, R ₁ is preferably lauryl, myristyl, palmityl, stearyl, oleyl, coco alkyl, palm nucleus alkyl, and R ₂ and R _{2. 3} is preferably methyl, ethyl, hydroxyethyl, etc., n is preferably 2 or 3, and R ₄ CO is lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, coconut oil fatty acid, palm kernel oil fatty acid. Is preferred.

Specific examples of the amine oxide represented by the general formula (I) include lauryldimethylamine oxide, myristyldimethylamine oxide, palmityldimethylamine oxide, stearyldimethylamine oxide,

The amount of component (B) blended in the detergent composition is
It is in the range of 0.1 to 20% by weight, preferably 0.5 to 5% by weight. If the blending amount is less than 0.1% by weight, the detergency and foamability are insufficient, and the interaction with the components (A) and (C) is not sufficient. On the other hand, if the blending amount exceeds 20% by weight, no remarkable blending effect is observed and it is uneconomical. The component (B) may be used alone or in combination of two or more.

Mixing ratio of component (B) and component (A) (B /
A) is preferably 0.1 to 50. When the compounding ratio is less than 0.1, the defoaming property tends to decrease, and when it exceeds 50, the foaming property tends to decrease.

Examples of the lower alkylbenzenesulfonic acid as the component (C) include benzenesulfonic acid, toluenesulfonic acid, xylenesulfonic acid and the like. These lower alkylbenzene sulfonic acids are not limited to the acid form, but potassium hydroxide, sodium hydroxide, ammonium hydroxide, monoethanolamine, diethylanolamine, diethylethanolamine, morpholine, etc. It is also possible to neutralize the whole and mix it as a water-soluble salt.

The amount of lower alkylbenzene sulfonic acid or its water-soluble salt as the component (C) to be added to the detergent composition is in the range of 0.1 to 20% by weight, preferably 1 to 10% by weight. If the blending amount is less than 0.1% by weight, the detergency,
The foam properties are both poor, and the interaction with the components (A) and (C) is not sufficient. On the other hand, when the blending amount exceeds 20% by weight, no remarkable blending effect is observed, and conversely, the foam property deteriorates. The component (C) may be used alone or in combination of two or more.

PH of the residential liquid cleaning composition of the present invention
Is in the range of 5 to 11, preferably 6 to 8. When the pH of the composition is less than 5 and more than 11, detergency,
Foam performance is poor, and it may adversely affect the object to be washed.

The liquid detergent composition for residential use of the present invention is obtained by blending the above-mentioned components (A), (B) and (C) as essential components and adjusting the pH of the composition to 5-11. However, these synergistic effects are inhibited by the amine component present in the composition. Therefore, in the present invention, a more stable effect can be expected by adjusting the amount of the amine component in the composition to 1000 ppm or less.

Further, in the present invention, other optional components may be appropriately blended if necessary. As these optional components, in order to improve detergency and foaming performance, a nonionic surfactant or the like can be blended as a surfactant other than the components (A) and (B). Furthermore, lower alcohols, ethylene glycol, bactericides, antiseptic and antifungal agents, fragrances, which are blended to maintain liquidity under low temperature or high temperature,
Dyes, antioxidants, thickeners, ultraviolet absorbers and the like can be optionally added. Incidentally, these optional components are usually
Any cleaning agent may be used as long as it is used as a cleaning agent, and is not particularly limited.
