Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is low-irritant, excellent in foaming properties, excellent in use after washing, and has a suitable detergency.
The present invention also relates to a cleaning composition having good aging stability.

[0002]

2. Description of the Related Art Detergent compositions depend on the type of object to be cleaned.
It is classified into body, clothing, hard surface, etc., and each has different characteristics in formulation. However, there is a common function required across all cleaning compositions, and these have been diversified in recent years. That is, in terms of performance, it is excellent in foaming properties, has an appropriate detergency, has excellent usability when actually used, and the composition is stable over time, and And so-called hypoallergenicity, and there is a demand for a detergent composition that satisfies these requirements in total. In order to obtain a mild cleaning composition, for example, attempts have been made to use mild surfactants. Examples of the mild surfactant include an amide ether sulfate ester type anionic surfactant.

As a composition using an amide ether sulfate ester type anionic surfactant, a composition combining an alkanolamide type nonionic surfactant (Japanese Patent Publication No. 1-60466) and an acyl glutamate type anionic surfactant are disclosed. Compositions Combined with Ionic Surfactants (JP-A 2-2
No. 35999), a composition comprising a combination of an acyl-β-alaninate type anionic surfactant (Japanese Patent Laid-Open No. 2-2 / 1990).
No. 22493), a composition comprising a combination of a sulfosuccinate salt type anionic surfactant (JP-A 2-2).
No. 32298) and the like. In these compositions, a sodium salt was used as an amide ether sulfate ester type anionic surfactant.

However, although a detergent composition using a sodium salt of an amide ether sulfate ester type anionic surfactant has low irritation, it is not preferable to come into contact with the skin at a high concentration, and There has been a need for an irritating cleaning composition. In addition, a detergent composition using a sodium salt of an amide ether sulfate ester type anionic surfactant has a problem that its stability with time, particularly at low temperatures, is poor. Furthermore, the detergent composition using the amide ether sulfate ester type anionic surfactant has elasticity to foam,
It also had the disadvantage of lack of sustainability.

[0005]

Therefore, it is hypoallergenic,
There has been a demand for a detergent composition which is excellent in foaming properties, feeling upon use after washing, has an appropriate detergency, and has good stability over time.

[0006]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and found that an arginine salt of amide ether sulfate and a nonionic surfactant are combined in a specific ratio. As a result, the above-mentioned drawbacks have been solved, and a cleaning composition having a characteristic that has not been achieved in the past has been obtained.

That is, the present invention provides the following (a):
(B) is contained, (a) + (b) is 5 to 60% by weight,
A cleaning composition, wherein the weight ratio between (a) and (b) is 1/20 to 20/1.

(A) Arginine salt of amide ether sulfate represented by formula (1)

[0009]

(Wherein R ¹ CO represents an aliphatic acyl group having 10 to 22 carbon atoms, and n represents an integer of 2 to 15); and (b) a nonionic surfactant.

According to the present invention, there is provided a detergent composition which is low-irritant, excellent in foaming properties, excellent in use after washing, has an appropriate detergency, and has good stability over time.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION An arginine salt of an amide ether sulfate represented by the formula (1) has R ¹ CO having 1 carbon atom.

Below, irritation to hair and skin becomes strong and carbon number is 23
Above, the foaming property and the stability over time are reduced.

N is an integer of 2 to 15. When n is less than 2, irritation to hair and skin is increased, and when it is more than 15, foamability is reduced.

The component (b) may be any non-ionic surfactant, for example, polyoxyethylene alkyl ether, polyoxyethylene alkyl phenyl ether, polyoxyethylene fatty acid ester, sorbitan ester, polyoxyethylene sorbitan. ester,

(A) + (b) is contained in an amount of 5 to 60% by weight, preferably 10 to 45% by weight. If the amount is less than 5% by weight, the foaming properties, foam quality and detergency are not good, and a favorable feeling in use cannot be obtained. On the other hand, if the content is more than 60% by weight, the irritation and detergency become too strong, so that a favorable feeling in use cannot be obtained and the stability with time decreases.

The weight ratio between (a) and (b) is 1/20 to 2
0/1, preferably 1/10 to 10/1. 1/2
If it is less than 0, good foam quality and favorable feeling in use cannot be obtained, and further, the stability with time deteriorates, and if it exceeds 20/1, the detergency decreases.
