Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a detergent composition, and more particularly to a detergent composition which exhibits high foaming properties even in hard water and has excellent skin feel after washing.

[0002]

2. Description of the Related Art Conventionally, a detergent composition containing a fatty acid soap as a main component and an anionic surfactant or an amphoteric surfactant in combination has been used. Although these have the advantage of high detergency and excellent refreshing feeling after washing, they combine with divalent metal ions in tap water during washing to produce metallic soap, which remains on the skin even after washing. However, it does not provide a moist touch, has the drawback of producing a tight feeling and a dry feeling, and when it is washed with hard water, a large amount of divalent metal soap is generated to reduce foaming properties. Problem.

For the purpose of improving the foaming power of such fatty acid soaps, it has been proposed to use an amphoteric surfactant in combination (JP-A-51-31706, JP-A-51-31707). Further, there has been proposed a detergent which has good foaming properties, good detergency and a good moist feeling after washing by using fatty acid soap in combination with alkiroylalkyltaurine and betainetrialkylaminoacetate (Japanese Patent Application Laid-Open No. Hei 6 (1994) -106). -88100). In addition, by using a fatty acid soap having a specific fatty acid composition in combination with an amidoamino acid-based amphoteric surfactant and an alkylloylalkyltaurine, a foaming agent having a good foaming property and a good rinsing property after washing (JP-A-6-248298) can be obtained. Gazette) has also been proposed.

On the other hand, as an application of amide ether carboxylic acid, there is known a detergent (US Pat. No. 4,865,575) using soap as a main component and blending amide ether carboxylic acid and alkyl ether carboxylic acid. ing.

However, none of these detergents has sufficient foaming properties in hard water, and the feeling of the skin after washing has not been sufficiently satisfactory.

[0006]

Therefore, there has been a demand for the development of a detergent composition which has a high foaming property even in hard water and which is excellent in skin feel after washing.

[0007]

Under these circumstances, the present inventors have studied a cleaning agent containing amide ether carboxylic acid and found that impurities such as polyoxyethylene glyceryl ether and polyoxyethylene glyceryl derived from raw materials were used. It was found that a foam containing a large amount of ether carboxylic acid or pure amide ether carboxylic acid itself had poor foaming properties. And as a result of further examination, it contains an amide ether in a specific ratio, and the glycerin derivative content is a certain ratio or less, and an amide ether derivative mixture, a fatty acid or a salt thereof, if a basic substance and a chelating agent are used in combination. The present inventors have found that a detergent composition having high foaming properties even in hard water and having an excellent feel after washing can be obtained, and the present invention has been completed.

That is, the present invention provides the following components (A), (B),
The present invention relates to a detergent composition comprising (C) and (D) and having a pH of 7.5 to 11. (A) An amide ether carboxylic acid represented by the general formula (1) or a salt thereof and an amide ether represented by the general formula (2),
(1) :( 2) = 99: 1 to 1: 9 in a weight ratio of 50
An amide ether derivative mixture containing at least 5% by weight of a glycerin derivative represented by the general formula (3) and not more than 5% by weight of the solid content.

It is preferably at least 70% by weight, particularly preferably at least 80% by weight. If the total content of these components is less than 50% by weight of the solid content, the foaming properties are poor, which is not preferable.

The weight ratio of the amide ether carboxylic acid or its salt (1) and the amide ether (2) contained in the component (A) is (1) :( 2) = 99: 1 to 10:90. It is necessary that the ratio be in the range of 95: 5 to 60:40, particularly 92: 8 to 70:30. If the ratio of the amide ether (2) is less than the above range (less than 1% by weight), the foaming property is poor, and if it exceeds the above range (more than 90% by weight), the whisking and rinsing are strong, Not preferred.

It can be added later. As a method of synthesizing the amide ether derivative mixture, a method of producing an alkanolamide using fatty acid lower alcohol esters such as fatty acid methyl ester as a starting material, a method of producing alkanolamide using oils and fats as a starting material, and a method of producing alkanolamide using fatty acids as a starting material Method and the like. Among them, a method of producing a fatty acid lower alcohol ester such as a fatty acid methyl ester as a starting material is preferable because the coloring is less and the glycerin derivative which is an impurity is not substantially contained. In the case of other methods, for example, a method in which a fat or oil having a coconut oil fatty acid composition is used as a starting material and directly converted into an alkanolamide and then subjected to alkoxylation and carboxymethylation, a large amount of a glycerin derivative derived from the fat or oil is produced and the compound (1)
And (2) are not practically preferable because the yield is low.
In the case of a method in which a fatty acid is reacted with an alkanolamine as a starting material to form an alkanolamide, the coloration is remarkable due to the high temperature of the amidation reaction, which is not preferable.
The ratio of the amide ether carboxylic acid (1) to the amide ether (2) in the amide ether derivative mixture of the component (A) is determined by the molar ratio and the mixing method when the amide ether (2) is reacted with an alkali monohaloacetate or the like.

The mixing ratio of the components (A) and (B) in the detergent composition of the present invention is not particularly limited, but the foaming property in hard water and the refreshing property after washing are as follows. From the viewpoint of feeling, (A) :( B) = 1: 99-75: 25, and further 5:95 by weight ratio.
~ 40: 60, particularly preferably from 5:95 to 40:60.

The basic substance (C) used in the present invention can be used alone or in combination of two or more. The amount of the component (C) in the detergent composition of the present invention varies depending on the type of fatty acid or salt thereof used, the degree of neutralization, and the like, but the pH of the detergent composition can be adjusted to 7.5 to 11. It needs to be an amount.

Further, the cleaning composition of the present invention has a pH of 7.5.
It is necessary to be 〜11, but it is particularly preferable that the sulphate is 7.5〜10.0 (measurement condition: 5% by weight aqueous solution of active ingredient). pH
If it is less than 7.5, the foaming property in hard water is inferior, and if the pH exceeds 11, foaming property, foam quality and rinsing properties are inferior, and skin irritation becomes strong. Adjust the pH as above
