BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described. The two-chain, two-polar group-containing anionic surfactant of the present invention has a long-chain hydrophobic group having 18, 16, 14, 12,
It is 10 or 8 and may have this type of molecular structure. An example is N, N'-bis [2-lauramidoethyl) ethylenediamine-N, N'-di (sodium acetate). A mixture with homologues having different hydrophobic groups in the molecular structure of this compound is also compounded within the scope of the object of the present invention. As the counter ion used here, a monovalent or divalent alkali metal ion, ammonium ion or organic ammonium ion is applied. However, as the organic ammonium ion, basic amino acids such as lysine and arginine are also applicable. In addition to N, N'-bis [2-lauramidoethyl) ethylenediamine-N, N'-di (sodium acetate), more specifically, N,
N'-bis [2-myristylamidoethyl) ethylenediamine-N, N'-di (sodium acetate), N, N'-

Examples thereof include -bis (myristoylamido) butane-N, N'-di (potassium acetate) and N, N'-bis (palmitoylamido) butane-N, N'-di (potassium acetate). The two-chain / two-polar group-containing anionic surfactant applicable to the present invention is limited to the compounds or homologues shown here and the mixture thereof as the two-chain / two-polar group-containing anionic surfactant. However, a printed matter (for example, Japanese Patent Laid-Open No. Hei 8
-1034646) is also included.

The N-acylalkyl taurate anionic surfactant according to the present invention has an acyl group having 10 carbon atoms.
To 22 and the alkyl group has 1 to 3 carbon atoms, and the counter ion is arbitrarily selected from monovalent or divalent alkali metal ions, ammonium ions or organic ammonium ions. The N-acyl amino acid-type anionic surfactant has an acyl group having 10 to 22 carbon atoms, and examples of the amino acid residue include glutamic acid, glycine, and alanine, but are not limited thereto, and include known ones. The counter ion is arbitrarily selected from monovalent or divalent alkali metal ions, ammonium ions or organic ammonium ions. In the sulfosuccinic acid type anionic surfactant, the hydrophobic group has 10 to 22 carbon atoms, and the counter ion is arbitrarily selected from monovalent or divalent alkali metal ions, ammonium ions or organic ammonium ions.

The higher fatty acid alkanolamide in the present invention means a condensation product of a higher fatty acid having 8 to 20 carbon atoms and an alkanolamine such as diethanolamine, monoethanolamine or isopropanolamine. It does not matter what is called a 2: 1 type or a 1: 1 type. As the higher fatty acid constituting this, a mixed system of coconut oil fatty acid and the like is also applied. The compounding amount of the higher fatty acid alkanolamide is 0.1 to 10% by weight.

(A) Two-chain / two-polar group-containing anionic surfactant of the present invention, and (b) N-acylalkyl taurate anionic surfactant, N-acylamino acid anionic surfactant, amide. The weight ratio of one or two or more selected from the group of ether sulfate-type anionic surfactants is 10/1 to 1/10 as (a) / (b).
If (a) / (b) is out of this range, foaming occurs, and the creamy feeling and rinsing feeling of the foam deteriorate.

The cosmetic detergent composition of the present invention may contain higher fatty acid soap. The alkyl group of the higher fatty acid soap applied here has 10 to 22 carbon atoms, and the counter ion is arbitrarily selected from monovalent or divalent alkali metal ions, ammonium ions or organic ammonium ions. When the cosmetic detergent composition of the present invention contains a higher fatty acid soap, the refreshing feel peculiar to the soap and the moist feel peculiar to the anionic surfactant containing a two-chain dipolar group according to the present invention synergistically foam. Improves the characteristics and feel of use. The higher fatty acid soap is usually incorporated in the cosmetic detergent composition of the present invention in an amount of 0.5 to 25% by weight. If it exceeds 25% by weight, the effect corresponding to it cannot be obtained.

The cosmetic detergent composition of the present invention has the composition as described above, but if necessary, other surfactants, emulsification aids, fragrances, colorants, preservatives, pigments and the like may be added to the present invention. It may be appropriately blended within a range that achieves the purpose. The cosmetic cleansing composition of the present invention is applied to a general cosmetic cleansing composition mainly for cleaning facial cleansers, liquid facial cleansers, body shampoos, shampoos and the like.

EXAMPLES The present invention is described below with reference to examples, but the present invention is not limited to these examples. The blending amount is% by weight. Evaluation of cosmetic-based detergent composition of Examples and Comparative Examples, the 10 subjects with the cosmetic-based detergent composition is made in sensory evaluation when the hair. That is, the head of the subject was divided into two parts, one of which was washed with 3 g of the standard sample A and the other of which was washed with 3 g of the test sample. Bubbling, i
i. Creamy sensation of bubbles; iii. The three items of sensation during rinsing were scored by the subjects' declaration. The scoring standard is +3 points if B is much better than A, +2 points if B is better than A, A
If B is slightly better, +1 point, if A and B are equal, 0 point, A
If B is worse, it is -2 points, and if B is much worse than A, it is -3 points. And the total obtained from 10 subjects is 30
~ 20 points are ◎, 19 to 10 points are ◯, 9 to -10 points are Δ,
-11 to -30 points are shown as x in the table. The standard sample A was prepared by adding sodium polyoxyethylene lauryl ether sulfate (additional mole number 3) 15%, N-lauroylglutamic acid triethanolamine 5%, coconut oil fatty acid diethanolamide 5% to water and adjusting the pH with citric acid. It is a cosmetic detergent composition adjusted to 7.

Examples 1 to 10 and Comparative Examples 1 to 8 Tables 1 and 2 show the compositions of the cosmetic cleaning composition (test sample) of the present invention. The formulations shown here exhibit the following: (1) Two-chain / two-polar group-containing anionic surfactant A1: N, N'-bis (lauroylamido) ethane-to be blended
N, N'-di (sodium acetate) A2: N, N'-bis (lauroylamido) ethane-
N, N′-di (sodium propionate) (2) N-acylalkyl taurate-type anionic surfactant, N-acylamino acid-type anionic surfactant, sulfosuccinic acid-type anionic surfactant blended, Alkyl ether sulfate B1: N-dodecyl-N-methyltaurine sodium B2: N-sodium dodecanoylglutamate B3: Dodecyl sulfosuccinate disodium (3) blended higher fatty acid alkanolamide C1: Lauric acid diethanolamide (4) blended Higher fatty acid soap D1: coconut oil fatty acid potassium

From Tables 1 and 2, it can be seen that when the hair was washed using the cosmetic cleaning composition of the example, all of the above evaluation items were superior to the case where the standard sample was used. Since it can be said that the standard sample is a well-known representative model, it is understood that the cosmetic detergent composition of the present invention is superior to the conventional product. On the other hand, cosmetic-based detergent composition of the performance of the cosmetic detergents cosmetics based detergent composition of the comparative example lacks the one of essential requirements such as components and blending amount ratio of the composition of the present invention present invention It turns out to be significantly worse than that. Further, it can be seen from Table 3 that the cosmetic detergent composition of the example containing the higher fatty acid soap is superior to the cosmetic detergent composition of the example not containing it.

Industrial Applicability As described above, the present invention is a cosmetic product having a good foaming property, an excellent creamy feeling of the foam, and a good rinsing feeling.
It is apparent to provide a system cleaner composition.
