Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition, and more specifically, it has low irritation on the skin and the like, excellent foaming property, creamy foam quality, and very high conditioning effect after cleaning. The present invention relates to a detergent composition having a transparent appearance.

2. Description of the Related Art Conventionally, the problems to be solved by the invention
As a surfactant for detergents, alkyl sulfate ester salt, polyoxyethylene alkyl sulfate ester salt, alkylbenzene sulfonate, α, which has the characteristics of high foamability
-Anionic surfactants such as olefin sulfonates are widely used.

Further, a quaternary ammonium salt or a tertiary amine has been blended with a detergent for hair in order to impart a conditioning effect to the hair after washing.

However, when an anionic surfactant is used in combination with a quaternary ammonium salt or a tertiary amine, a water-insoluble complex is formed and becomes cloudy / separated in an aqueous solution, so that the foamability of the detergent is lowered. However, a sufficient conditioning effect cannot be obtained, and therefore, other conditioning components have been used in combination.

In order to solve these problems, JP-A-62-2
88694 discloses a combination of an amphoteric surfactant, a quaternary ammonium salt and a carboxylic acid type anionic surfactant, and JP-A-63-317596 discloses a nonionic surfactant, a quaternary ammonium salt and a carboxylic acid type surfactant. Although it is said that a combination of anionic surfactants can form a transparent and soluble complex in water to impart a good conditioning effect, the present situation is that it has not yet been satisfactory as a personal cleansing agent.

[0006] Nonionic surfactants are suitable as cleansing agents in that they have low irritation to the skin, as represented by alkyl polyglycosides, but they have a squeaky feeling in the process from washing to rinsing. Because it is strong
Various studies have been conducted to eliminate the tingling sensation, as typified by the combination with the cationic polymer described in JP-A No. 5 (1993), but no satisfactory one has been obtained yet.

On the other hand, the amide ether carboxylic acid type surfactant is known as a mild surfactant. This amide ether carboxylic acid surfactant is commercially available from Chem Y of Germany under the trade name of "Akipo". This product is derived from amide ether carboxylic acid, the raw material amide ether, and other raw materials. Impurities such as polyoxyethylene glyceryl ether, polyoxyethylene glyceryl ether carboxylic acid, and inorganic salts are included.

[0008] Conventionally known techniques for applying amide ether carboxylic acid surfactants to detergents are amide ether carboxylic acids, polyoxyethylene alkyl sulfates, fatty acid diethanolamides and higher alcohol alkylene oxides. Detergent combined with adduct, acyl sarcosinate, etc. (European Patent No. 102118), a method of using amide ether carboxylic acid type surfactant and polyoxyethylene alkyl sulfate ester in combination (European Patent No. 215504) ), A foam bath in which amide ether carboxylic acid starting from fats and oils is combined with lauryl sulfate ester, lauryl ether sulfate ester, alkyl ether carboxylic acid, quaternary compound obtained by reacting lauric acid with glycidyl trimethyl ammonium chloride, etc. Agents, shampoo agents, shower agents and the like (JP-B 63-291996, JP-EP 2
19893), detergents containing amide ether carboxylic acid or alkyl ether carboxylic acid salt containing soap as a main component (US Pat. No. 4,865,757), and the like.
However, none of these detergents is still satisfactory in terms of foamability.

Therefore, there has been a demand for the development of a detergent composition which has a low irritation to the skin and the like, a high foaming property, and a high conditioning effect.

[0010]

Under the circumstances, the inventors of the present invention have conducted extensive studies and as a result, when amide ether carboxylic acid and a quaternary ammonium salt or a tertiary amine were mixed in a specific ratio, they were transparent to water. A soluble complex is formed to improve the slipperiness during washing, and a very high conditioning effect can be imparted. Furthermore, by blending this with a nonionic surfactant, the slipperiness and high conditioning effect of this complex are improved. The present invention has been completed by finding that a transparent detergent having a high foaming property and a low irritation to the skin or the like can be obtained without impairing the above.

That is, the present invention provides the following components (A), (B) and
(C) (A) Amido ether carboxylic acid represented by the general formula (1) or a salt thereof
