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 little irritation to the skin, has an excellent foaming property, has a creamy foam quality, and cleans even in a region where water hardness is high. The present invention relates to a detergent composition capable of imparting a good feel to the skin afterward.

[0002]

2. Description of the Related Art Conventionally, as surfactants for detergents, anions such as alkyl sulfate ester salts, polyoxyethylene alkyl sulfate ester salts, alkylbenzene sulfonates and α-olefin sulfonates, which have the characteristic of high foaming property. Surfactants are widely used. However, all of these anionic surfactants have skin irritation to varying degrees, but when they are continuously used, they have a problem of roughening the skin.

On the other hand, a phosphoric acid ester-based surfactant containing a monoalkylphosphoric acid as a main component, which is a mild stimulant, has a low stimulative property and has a good foaming property and foam quality, In a region of high hardness, there was a problem that the Ca salt of phosphate ester remained on the skin even after washing and rinsing, giving a slightly dry feel. As other mild surfactants, alkyl saccharide-based surfactants, sulfosuccinic acid-based surfactants, ethercarboxylic acid-based surfactants, amide ethercarboxylic acid-based surfactants and the like are known. However, although the alkyl saccharide-based surfactants have high foaming properties, they have strong creases during washing and rinsing, and therefore are used in combination with a conditioning agent such as a cationic polymer (JP-A-2-42013). Although it has been proposed, it is not technically easy to add a large amount to shampoo or the like. Further, a method in which a sulfosuccinic acid-based surfactant alone has poor foaming properties and is used in combination with other surfactants (Japanese Patent Laid-Open No. 2-218797) and the like have been proposed. Often used in combination. Furthermore, commercially available ether carboxylic acid type surfactants and amido ether carboxylic acid type surfactants also have poor foaming properties, and are used only as auxiliary surfactants in detergents that require high foaming properties. ing.

This amide ether carboxylic acid type surfactant is marketed under the trade name of "Akipo" by Chem Y GmbH of Germany. This product includes amide ether carboxylic acid, amide ether as a raw material thereof, and a raw material. Polyoxyethylene glyceryl ether, polyoxyethylene glyceryl ether carboxylic acid, inorganic salts, and the like, which are impurities derived from, are included.

[0005] As a technique known so far regarding application of an amide ether carboxylic acid type surfactant to a detergent, amide ether carboxylic acid, polyoxyethylene alkyl sulfuric acid ester, fatty acid diethanol amide, higher alcohol alkylene oxide are known. Detergent combined with an adduct, acyl sarcosinate, etc. (European Patent No. 102118), a method in which an amide ether carboxylic acid surfactant and a polyoxyethylene alkyl sulfate are used in combination (European Patent No. 215504). ), Amide ether carboxylic acid starting from fat and oil, lauryl sulfate ester, lauryl ether sulfate ester, alkyl ether carboxylic acid, lauric acid and glycidyl trimethyl ammonium chloride were reacted 4
Foam bath agents, shampoo agents, shower agents, etc. in combination with graded products (Japanese Patent Publication No. 63-291996, European Patent No. 219893), amide ether carboxylic acids and alkyl ethers mainly composed of soap Detergent containing carboxylic acid salt (US Pat. No. 4,865)
757 specification) and the like. However, none of these detergents is still satisfactory in terms of foamability.

[0006]

(In the formula, R ⁷ is a hydrogen atom,-(CH ₂ CH ₂ O) _p CH ₂
COOM or - indicates a _{(CH 2 CH 2 O) q} H ( wherein p, q and M are as defined above). )

The content of the glycerin derivative (5) is preferably 5% by weight or less, and more preferably 3% by weight or less, substantially not contained in the solid content of the component (B). When the content of the glycerin derivative (5) is high,
The foaming property is remarkably reduced, which is not preferable. Further, it is preferable that the content of the inorganic salt such as sodium chloride which is an impurity other than the glycerin derivative (5) in the component (B) is small.

The amide ether carboxylic acids (3) used in the present invention are, for example, European Patent No. 219893.
The method for producing a mixture of the compounds of formulas (3) and (4) (hereinafter sometimes referred to as an amide ether derivative mixture) is not particularly limited, and an amide ether ( It can also be produced directly by reacting a portion of 4) with halogen acetic acid, or the amide ether (4) can be post-added to the amide ether carboxylic acid (3). As a method for synthesizing amide ether (4), which is an intermediate for producing amide ether carboxylic acid (3), alkanolamine is reacted with fatty acid lower alcohol ester such as fatty acid methyl ester as a starting material, and then polyoxyethylenated. Examples thereof include a method, a method of reacting an alkanolamine with a fat and oil as a starting material and then polyoxyethylene-ized, a method of reacting an alkanolamine with a fatty acid as a starting material, and then polyoxyethylene-ized. Among them, the method of producing a fatty acid lower alcohol ester such as fatty acid methyl ester as a starting material is preferable because it is less colored and does not substantially contain the glycerin derivative as an impurity. In the case of another method, for example, a method in which an oil and fat having a coconut oil fatty acid composition is used as a starting material and a polyalkoxylene is directly reacted with an alkanolamine, a large amount of a glycerin derivative (5) derived from the oil and fat is generated, and a compound ( 4) As a result, the yield of the compound (3) decreases, which is not preferable in practice. Further, in the case of a method of reacting an alkanolamine with a fatty acid as a starting material, the amidation reaction is carried out at a high temperature, so that coloring is remarkable, which is not preferable. The ratio of the amide ether carboxylic acid (3) and the amide ether (4) in the amide ether derivative mixture of the component (B) is
It can be adjusted by selecting reaction conditions such as a molar ratio and a mixing method when the amide ether (4) is reacted with an alkali salt of monohaloacetic acid.

The blending amounts of the component (A) and the component (B) in the detergent composition of the present invention are not particularly limited, but are usually 0.5 to 40% by weight, and more preferably 1%. Is about 20% by weight. If the amount of the component (A) is too small, the foamability and the creaminess of the foam quality are insufficient, and if the amount of the component (B) is too small, the phosphoric acid ester-based surfactant C is used.
Due to a salt formation, the skin feels poor after washing in areas of high water hardness. Further, the mixing ratio of the component (A) and the component (B) is not particularly limited, but usually (A) / (B) = 99/1 to 1/99, preferably 97 / 3 to 20/80, particularly preferably 95/5 to 6
It is 0/40.

Further, when the phosphoric acid ester type surfactant as the component (A) is neutralized with a triethanolamine salt or an alkali metal salt, the viscosity of the phosphoric acid ester salt is rapidly increased at a concentration of 30% by weight or more. There is a problem that gelation occurs and it becomes difficult to further increase the concentration of the component (A). That is, when the phosphate ester-based surfactant neutralized product was applied to the final formulation, the use concentration was naturally limited. On the other hand, when the component (A) is combined with the component (B), the detergency is improved while maintaining the mildness, and the phosphoric acid ester salt has a low viscosity even at a high concentration of 30% by weight or more. A composition is obtained. The effect that the concentration of the phosphate ester salt can be increased is particularly remarkable when p and q in the general formulas (3) and (4) are 3 to 15 as the component (B).

The detergent composition of the present invention is not particularly limited, but a pH of 3 to 9 is preferable, and a pH of 4 to 8 is more preferable.
(PH measurement condition; 5% by weight active ingredient in water).
