Description

[Technical Field]

[0001] The present invention relates to a cleaning agent, and in particular to a cleaning agent containing an amino acid-based surfactant and / or a taurine-based surfactant, which has improved transparency and viscosity. [Background technology]

[0002] In recent years, the number of people with so-called "sensitive skin," which is sensitive to irritants, has been increasing. Many of these people experience skin problems due to surfactants and other substances. In particular, detergents such as shampoos contain large amounts of surfactants, which often cause skin problems. Therefore, amino acid-based surfactants and taurine-based surfactants, which are highly safe and have cleaning effects, are being used in detergents.

[0003] For example, Patent Document 1 discloses a viscous composition containing (A) at least a copolymer obtained by polymerizing 100 parts by mass of (meth)acrylic acid and 0.5 to 5 parts by mass of a (meth)acrylic acid alkyl ester having 10 to 30 carbon atoms in the alkyl group, (B) an amino acid surfactant, (C) betaine, (D) an alkyl glycoside, and (E) an organic acid salt, wherein the mass content of (B) is equal to or greater than the mass content of (C).

[0004] Furthermore, Patent Document 2 discloses a hair washing cosmetic composition characterized by containing (A) N-acylmethyltaurine or a salt thereof, (B) N-acylmethylalanine or a salt thereof, (C) an amphoteric surfactant, (D) cationized cellulose, and (E) polyoxyethylene fatty acid methyl glucoside, and having a pH of 5.5 to 6.5.

[0006] However, although the technologies described in Patent Documents 1 and 2 examine viscosity, they require a thickener as an essential component, which may impair the cleaning power of the surfactant, and improvements in this area have been desired.

[0007] In addition, in recent years, transparent detergents have become popular due to their beautiful appearance, but the technologies described in Patent Documents 1 and 2 have not been considered at all, and there has been a demand for the development of even more transparent detergents.

[0008] Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art and to provide a cleaning agent containing an amino acid-based surfactant and / or a taurine-based surfactant having improved transparency and viscosity. [Means for solving the problem]

[0009] As a result of intensive research to solve the above-mentioned problems, the inventors discovered that the above-mentioned object can be achieved by combining an amino acid-based surfactant and / or a taurine-based surfactant with a specific anionic surfactant, and thus completed the present invention.

[0010] That is, the detergent of the present invention comprises, as component (A), a compound represented by the following general formula: A surfactant (sodium alkanesulfonate) represented by JPEG2026017560000002.jpg28134, (B) as a component, an amino acid-based surfactant and / or a taurine-based surfactant; (C) as a component, an alkyl alkanol type nonionic surfactant; The present invention is characterized in that it contains:

DETAILED DESCRIPTION OF THE INVENTION

[0015] The cleaning agent of the present invention will be specifically described below. The cleaning agent of the present invention contains, as component (A), a compound represented by the following general formula: a surfactant represented by JPEG2026017560000003.jpg28134; (B) as a component, an amino acid-based surfactant and / or a taurine-based surfactant; The composition is characterized by containing an alkylalkanol-type nonionic surfactant as component (C), thereby providing a cleaning agent containing an amino acid-based surfactant and / or a taurine-based surfactant with improved transparency and viscosity.

[0016] In the present invention, the component (A) is represented by the following general formula: The surfactant (sodium alkanesulfonate) represented by JPEG2026017560000004.jpg28134 is not particularly limited as long as it is usable in cleaning agents. For example, a surfactant with the display name of sodium alkyl(C14-17) s-sulfonate can be used. Commercially available products that can be used include WeylClean (registered trademark) SAS60 and WeylClean (registered trademark) SAS93, both of which are sold by Azelis Japan Co., Ltd.

[0017] The cleaning agent of the present invention further comprises, as the component (A), a compound represented by the following general formula: It is preferable to contain 1 to 10% by mass of a surfactant represented by JPEG2026017560000005.jpg28134. If the content of component (A) is less than 1% by mass, there is a risk that the viscosity will not increase, whereas if it is more than 10% by mass, there is a risk that the viscosity will become too high, which is not preferable.

[0018] In the present invention, the amino acid surfactant as component (B) is an anionic surfactant in which an acyl group such as a fatty acid residue reacts with an amino acid such as glutamic acid, aspartic acid, glycine, or alanine in the structure. There is no particular limitation as long as it can be used in a cleaning agent. Examples of such surfactants include N-acyl alanine surfactants such as N-coconut oil fatty acid alanine salt, N-lauroyl alanine salt, and N-myristoyl alanine salt; N-acyl methyl alanine surfactants such as N-coconut oil fatty acid methyl alanine salt, N-lauroyl methyl alanine salt, and N-myristoyl methyl alanine salt; ... Examples of the salt form of the amino acid-based anionic surfactant include N-acyl glutamate surfactants such as oil fatty acid acyl glutamate, N-lauroyl glutamate, N-myristoyl glutamate, N-palmitoyl glutamate, N-stearoyl glutamate, and N-oleoyl glutamate; and N-acyl sarcosinate surfactants such as N-coconut oil fatty acid sarcosine salt, N-lauroyl sarcosine salt, N-myristoyl sarcosine salt, and N-oleoyl sarcosine salt. Examples of the salt form of the amino acid-based anionic surfactant include sodium salt, potassium salt, and triethanolamine salt. Among these, N-acylmethylalanine surfactants such as N-coconut oil fatty acid sodium alanine, N-coconut oil fatty acid sodium methylalanine, and lauroylmethyl-β-alanine sodium, and N-acylglutamic acid surfactants such as N-coconut oil fatty acid acyl-L-glutamic acid triethanolamine are preferred, and commercially available products such as MIAMI SCA(S) and MIAMI CT130(S) manufactured by Miwon Commercial Co., Ltd. can be used.

[0019] Furthermore, in the present invention, the taurine-based surfactant used as component (B) is an anionic surfactant in which an acyl group such as a fatty acid residue is reacted with N-methyltaurine in the structure, and is not particularly limited as long as it can be used in cleaning agents, but an example of such an anionic surfactant is sodium coconut oil fatty acid methyltaurate. Furthermore, a commercially available product such as MIAMI CMT manufactured by Miwon Commercial Co., Ltd. can be used.

[0020] The cleanser of the present invention preferably contains 1 to 15% by mass of the component (B). If the content of the component (B) is less than 1% by mass, fine foaming may be lost, while if it is more than 15% by mass, thickening may not occur, which is undesirable.

[0021] Furthermore, in the present invention, the alkylalkanol-type nonionic surfactant used as component (C) is a polyhydric alcohol-type nonionic surfactant having an amide bond formed by bonding a compound having an amino group and a hydroxyl group to a fatty acid. It is not particularly limited as long as it is suitable for use in detergents. Examples include coconut oil fatty acid N-methylethanolamide, coconut oil fatty acid monoisopropanolamide, coconut oil fatty acid diethanolamide, lauric acid diethanolamide, palm kernel oil fatty acid diethanolamide, stearic acid monoethanolamide, and lauric acid monoisopropanolamide. Among these, one or more surfactants selected from the group consisting of coconut oil fatty acid N-methylethanolamide, coconut oil fatty acid monoisopropanolamide, coconut oil fatty acid diethanolamide, and lauric acid diethanolamide are preferred. Commercially available products include MICOPOL CMM, MICOPOL CIP, MICOPOL LDE, and MICOPOL CDE, both manufactured by Miwon Commercial Co., Ltd.

[0022] The detergent of the present invention preferably contains 1 to 8% by mass of the component (C). If the content of the component (C) is less than 1% by mass, there is a risk that the viscosity will not increase, whereas if it is more than 8% by mass, there is a risk of gelation, which is not preferred.

[0023] In the present invention, the cleanser is not particularly limited as long as it can be used on human hair or the body, and is primarily a cosmetic product, but does not exclude applications in quasi-drugs, pharmaceuticals, etc. Specifically, it can be used in shampoos, body shampoos, cleansing cosmetics, etc.

[0024] Furthermore, in the present invention, other ingredients may be added as appropriate within the range that does not impair the effects of the present invention. Any ingredients other than those described above may be contained (blended) within the qualitative and quantitative ranges, and ingredients that are usually blended into cleansing agents, such as surfactants other than those described above, oily ingredients, moisturizers, antioxidants, fragrances, various vitamins, chelating agents, colorants, UV absorbers, medicinal ingredients, inorganic salts, etc. may be blended.

[0025] Examples of ingredients that can be added include nonionic surfactants, such as mono-fatty acid polyglyceryl, poly-fatty acid polyglyceryl, polyoxyethylene glycerin fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene sorbit fatty acid ester, polyoxyethylene propylene glycol fatty acid ester, polyoxyethylene castor oil derivative, polyoxyethylene hydrogenated castor oil derivative, polyoxyethylene sterol, polyoxyethylene hydrogenated sterol, polyethylene glycol fatty acid ester, polyoxyethylene alkyl ether, polyoxyethylene polyoxypropylene alkyl ether, sucrose fatty acid ester, etc.

[0026] Examples of amphoteric surfactant components include imidazoline-based amphoteric surfactants such as 2-undecyl-N,N,N-(hydroxyethylcarboxymethyl)-2-imidazoline sodium and 2-cocoyl-2-imidazolinium hydroxide-1-carboxyethyloxy 2-sodium salt, and betaine-based surfactants such as 2-heptadecyl-N-carboxymethyl-N-hydroxyethylimidazolinium betaine, lauryldimethylaminoacetic acid betaine, alkyl betaine, amido betaine, and sulfobetaine.

[0027] Examples of polyhydric alcohols include one or more selected from the group consisting of glycerin, 1,3-butylene glycol, propylene glycol, propanediol, 1,2-hexanediol, pentylene glycol, pentaerythritol, hexylene glycol, diglycerin, polyglycerin, diethylene glycol, polyethylene glycol, dipropylene glycol, polypropylene glycol, ethylene glycol-propylene glycol copolymer, and polymers thereof.

[0032] Examples of ultraviolet absorbers include benzophenone derivatives such as 2-hydroxy-4-methoxybenzophenone, para-aminobenzoic acid derivatives such as para-aminobenzoic acid, methoxycinnamic acid derivatives such as octyl paramethoxycinnamate, salicylic acid derivatives such as octyl salicylate and phenyl salicylate, urocanic acid, ethyl urocanate, 4-tert-butyl-4'-methoxydibenzoylmethane, and benzotriazole.

[0033] In the present invention, the detergent can be produced by a conventional method for producing detergents.

[0034] In the present invention, the range of the increased viscosity is sufficient as long as the viscosity of the cleaning agent when the (B) component is replaced with the (A) component is improved compared to the cleaning agent when the (B) component is not replaced with the (A) component. For example, when the (B) component is an N-acylalanine surfactant, the range of the increased viscosity is preferably 1000 mPa·s to 6000 mPa·s. A viscosity lower than 1000 mPa·s may cause the cleaning agent to run when picked up, while a viscosity higher than 6000 mPa·s may cause the cleaning agent to be difficult to dispense from a pump, which is undesirable. Any method capable of measuring viscosity can be used. For example, a Brookfield viscometer (model RB-80L or TVB-10m: manufactured by Toki Sangyo Co., Ltd.) can be used at 25°C with rotor No. 3 at 20 rpm, with the measurement time set to 30 seconds.

[0035] The present invention will be described in more detail below using examples, but the present invention is not limited to these examples. Note that the numbers in the following tables regarding formulations indicate mass % and indicate the actual blend amounts of the components. [Example]

[0036] [Experimental Example 1] Shampoos of Example 1 and Comparative Examples 1 and 2 were prepared according to the formulations shown in Table 1 below. The appearance and viscosity of the resulting shampoos were measured, and the results are shown in FIGS.

The shampoo of Example 1 was clearer than the shampoo of Comparative Example 1. Furthermore, although N-coconut oil fatty acid sodium alanine alone, as in the shampoo of Comparative Example 1, did not produce any viscosity at all, by replacing 3% by mass of N-coconut oil fatty acid sodium alanine with sodium alkane sulfonate, as in the shampoo of Example 1, it was possible to increase the viscosity by more than three times compared to when 3% by mass of N-coconut oil fatty acid sodium alanine was replaced with sodium tetradecene sulfonate, as in the shampoo of Comparative Example 2.

[0039] [Experimental Example 2] Shampoos of Example 2 and Comparative Examples 3 and 4 were prepared according to the formulations shown in Table 2 below. The appearance and viscosity of the resulting shampoos were measured, and the results are shown in FIGS.

The shampoos of Example 2, Comparative Example 3, and Comparative Example 4 were all transparent. Furthermore, while the shampoo of Comparative Example 3 did not produce any viscosity at all using only N-coconut oil fatty acid acyl-L-glutamic acid triethanolamine, by replacing 4% by mass of N-coconut oil fatty acid acyl-L-glutamic acid triethanolamine with sodium alkanesulfonate, as in the shampoo of Example 2, the viscosity was increased by more than 14 times compared to the shampoo of Comparative Example 4, in which 4% by mass of N-coconut oil fatty acid acyl-L-glutamic acid triethanolamine was replaced with sodium tetradecenesulfonate. As described above, Experimental Examples 1 and 2 demonstrated that the inclusion of component (A) resulted in a thickening effect exceeding 3,000 mPa.s at 3% by mass or more of an N-acylalanine surfactant and at 4% by mass or more of an N-acylglutamic acid surfactant, which is difficult to thicken.
