DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning composition having good lathering, excellent lathering feeling, and good rinsing performance.

[0002]

2. Description of the Related Art Conventionally, a cleaning composition which is used for cleaning the body and hair has been studied which is excellent in foaming and creaminess of foam and has a good rinsing feeling. For example, in order to improve the feeling of rinsing during hair washing, an attempt has been made to blend a cationic polymer such as cationic cellulose with a normal (single-chain, one-polar-group-containing) anionic surfactant which is a main ingredient of a hair cleaning agent. It has been recognized that this formulation improves the rinsing feel. This is because an anionic surfactant for hair washing, such as polyoxyethylene lauryl ether sulfate or alkyl sulfate, forms a complex salt with a cationic polymer upon rinsing and is adsorbed on hair. On the other hand, the blending of the cationic polymer has disadvantages such as hardening of the hair at the time of rinsing or finishing. Therefore, recently, a hair cleaning agent containing an amphoteric surfactant and a specific amphoteric polymer has been studied. When this is used, defects such as hardening of hair at the time of rinsing or finishing can be solved, but it cannot be said that foaming and creaminess of foam are sufficiently satisfied. As described above, a cleaning composition having good foaming, excellent foam creaminess, and good rinsing performance has not yet been developed, and improvement thereof has been desired.

[0003]

The present inventor has made intensive studies to improve such disadvantages of the prior art, and as a result,
Specific two-chain anionic surfactant containing a dipolar group and one-chain one
The present inventors have found that a detergent composition containing a polar group-containing anionic surfactant and a higher fatty acid alkanolamide remarkably improves the above disadvantages, and have completed the present invention. That is, an object of the present invention is to provide a detergent composition which has good foaming, is excellent in creamy feeling of foam, and has good performance at the time of rinsing.

A mixture with a homologue having a different hydrophobic group in the molecular structure of the compound is also blended within the scope 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, basic amino acids such as lysine and arginine also correspond to the organic ammonium ion. In addition to N, N'-bis [2-lauramidoethyl) ethylenediamine-N, N'-di (sodium acetate), more specifically,
N'-bis [2-myristoylamidoethyl) ethylenediamine-N, N'-di (sodium acetate), N, N'-

Also known are those known as.

Among the one-chain and one-polar group-containing anionic surfactants according to the present invention, those containing a carboxyl group mean firstly those generally called soaps having 10 to 10 carbon atoms.
It refers to up to 20 and is usually used as a mixed fatty acid regardless of animal origin, plant origin, or synthetic product. The counter ion is arbitrarily selected from monovalent or divalent alkali metal ions, ammonium ions and organic ammonium ions. Further, among the anionic surfactants containing one long chain and one polar group in the present invention, those containing a carboxyl group are those having N
-Means an acyl amino acid-based anionic surfactant collectively, having an acyl group of 10 to 20 carbon atoms,
The constituent amino acids include glutamic acid, glycine, alanine, valine, taurine and the like. Further, the anionic surfactant containing one long-chain and one polar group in the present invention means a surfactant containing a polar group other than the above-mentioned carboxyl group, that is, a sulfonic acid group, a sulfate group, and a phosphate group. That is, alkane sulfonates, α-olefin sulfonates, sulfonates of higher fatty acid esters, sulfonates of higher fatty acid amides, sulfonates such as sulfosuccinates, alkyl sulfates, alkyl ether sulfates, higher fatty acid esters Sulfates, such as sulfates of higher fatty acid alkylolamide, and phosphates such as alkyl phosphates and alkyl ether phosphates. The counter ion of the anionic surfactant containing one long-chain and one polar group is arbitrarily selected from monovalent or divalent alkali metal ions, ammonium ions and organic ammonium ions. Here, it goes without saying that basic amino acids such as lysine and arginine also correspond to the organic ammonium ion. One or more of these one long-chain and one polar group-containing anionic surfactants are blended in the cleaning composition of the present invention.

[0007] The higher fatty acid alkanolamide in the present invention means a condensation product of a higher fatty acid having 8 to 20 carbon atoms with an alkanolamine such as diethanolamine, monoethanolamine and isopropanolamine. It does not matter what is called the 2: 1 type or the 1: 1 type. As a higher fatty acid constituting this, a mixed system of coconut oil fatty acid and the like is also applied. The blending amount of the higher fatty acid alkanolamide is 10 to 0.5% by weight.

The mixing weight ratio of the two-chain, two-polar group-containing anionic surfactant to the one long-chain, one-polar group-containing anionic surfactant in the present invention is preferably 15: 1 to 3: 1. Even if the weight ratio of the two-chain, two-polar group-containing anionic surfactant to the one long-chain, one-polar group-containing anionic surfactant exceeds 15, the effect does not increase as expected. On the other hand, when the weight ratio of the two-chain two-polar group-containing anionic surfactant to the one long-chain one-polar group-containing anionic surfactant 1 is less than 3, the effect on the foam is reduced. The total amount of the two-chain, two-polar group-containing anionic surfactant and the one long-chain, one-polar group-containing anionic surfactant in the detergent composition of the present invention is 35 to 3% by weight.

The detergent composition of the present invention comprises the above-mentioned composition. If necessary, other detergents, emulsifying auxiliaries,
Flavors, colorants, preservatives, pigments, and the like can be appropriately blended within a range that achieves the object of the present invention. The cleaning composition of the present invention is applied to ordinary cosmetic cleaning compositions mainly for the purpose of cleaning face-wash creams, liquid facial cleansers, body shampoos, shampoos and the like.

Foam creamy feeling; iii. Presence or absence of creaking, iv. Finger passage (smoothness), v. Five items of the softness of the hair were scored by the report of the subjects. The scoring criteria are +3 points when B is better than A, +2 points when B is better than A, +1 point when B is slightly better than A, 0 point when A and B are equal, and-when B is worse than A. 2 points, and -3 points when B was much worse than A.

From Table 1, it can be seen that when the hair was washed using the cleaning compositions of the examples, all of the above evaluation items were better than when the standard samples were used. Since the standard sample is a known representative model, it can be seen that the cleaning composition of the present invention is superior to the conventional product. On the other hand, it can be seen that the performance of the cleaning composition of the comparative example lacking any one of the components of the cleaning composition of the present invention is much worse than that of the cleaning composition of the present invention.
