Description

Technical Field

[0001] The present invention relates to a detergent composition, and more particularly to a detergent composition that has reduced irritation to the skin and additionally has an effect of suppressing skin itching.

Background Art

[0002] In recent years, the number of consumers who recognize themselves as having sensitive skin has been increasing, and there has been a demand for products having not only a cleaning function but also additional value-added functions such as irritation-reducing properties for the skin. Conventional detergent compositions can be applied in a pH range close to that of the skin in order to achieve irritation-reducing properties, and contain an amino acid-based surfactant having low irritation to the skin, combined with a betaine-based amphoteric surfactant and a nonionic surfactant (for example, Patent Document 1), or a combination of a higher fatty acid salt, an acyl glycinate, an acyl aspartate, and an acyl methyl taurine salt, to provide a detergent composition having detergency, biofilm removal ability, and low skin irritation (for example, Patent Document 2). However, these detergent compositions have a problem in that the foaming property and foam quality (elasticity), which are basic performances as a detergent composition when consumers use cleaning agents such as facial washes and body soaps, are insufficient. Therefore, in order to solve the problems related to the foaming property and foam quality (elasticity) which are basic performances, a detergent composition having rich foaming property is obtained by blending an acyl aspartate and an acyl methyl taurine Mg salt (for example, Patent Document 3), or a liquid detergent composition having dense and less stiff foam is developed by blending a cationic polymer and a cationized polysaccharide (for example, Patent Document 4), and the like.

[0004] However, in the above "detergent composition", the detergent composition itself is only mildly irritating to the skin, and has no effect of suppressing irritation such as itching induced by irritation, and does not provide any solution to the skin problems that have already occurred.

[0005] The present invention has been made in view of the above problems, and an object thereof is to provide a detergent composition having good foam quality (elasticity) and additionally having an effect of suppressing skin itching induced by irritation. [Means for Solving the Problems]

[0006] As a result of intensive studies to achieve the object of the present invention, the present inventors have found that by combining glycyrrhizic acid or its salt, N-acylaspartate, amidosulfobetaine-type amphoteric surfactant, and N-acylmethyltaurine salt, a detergent composition having good foam quality (elasticity) and additionally having an effect of suppressing skin itching induced by irritation can be obtained, and the present invention has been completed.

[0007] That is, the detergent composition according to the present invention (A) glycyrrhizic acid or its salt, (B) N-acylaspartate, (C) N-acylmethyltaurine salt, (D) amidosulfobetaine-type amphoteric surfactant, and contains

[0008] In the detergent composition according to the present embodiment, the blending amount of (A) may be 0.001% by mass or more and 0.1% by mass or less based on the total amount of the detergent composition. [Effect of the Invention]

[0009] According to the present invention, it is possible to provide a detergent composition having good foam quality (elasticity) and further having an effect of suppressing itching of the skin induced by irritation. [Embodiments for Carrying Out the Invention]

[0010] Hereinafter, the detergent composition of the present invention will be described in detail.

[0011] [Component (A) Glycyrrhizic acid or its salt] Component (A) used in the detergent composition of the present invention is glycyrrhizic acid or its salt. By blending component (A), an itching suppressing effect due to anti-inflammation can be imparted. Component (A) is not particularly limited as long as it is glycyrrhizic acid, its salt, or its derivative, and can be appropriately selected according to the purpose. Examples of component (A) include trisodium glycyrrhizate, dipotassium glycyrrhizate, monoammonium glycyrrhizate, and the like. From the viewpoints of stability and its effectiveness, dipotassium glycyrrhizate is preferable as component (A). In the detergent composition of the present invention, these glycyrrhizic acids or their salts may be used alone or in combination of two or more.

[0012] In the detergent composition of the present invention, the blending amount of component (A) is preferably 0.001% by mass or more and 0.1% by mass or less, more preferably 0.003% by mass or more and 0.05% by mass or less, based on the entire detergent composition. If the blending amount of component (A) is 0.001% by mass or more, a good itching suppressing effect can be obtained, and if it is 0.1% by mass or less, the stability at low temperature (stability over time) can be made good, and the generation of precipitates can be suppressed. When component (A) is used in combination of two or more, the blending amount of component (A) is the total thereof.

[0013] [Component (B) N-acyl aspartate] Component (B) used in the detergent composition of the present invention is N-acyl aspartate. By blending component (B), it is possible to suppress the roughness of the skin after washing and impart an effect of suppressing itching due to dryness. Such an acyl group is preferably a fatty acid residue having 8 to 22 carbon atoms. For example, a single acyl group such as lauric acid, myristic acid, palmitic acid, stearic acid, isostearic acid, oleic acid, an acyl group derived from coconut oil fatty acid, beef tallow fatty acid, castor oil fatty acid, olive oil fatty acid, palm oil fatty acid, or a mixture thereof can be mentioned. Examples of the salt of N-acyl aspartic acid include alkali metal salts such as sodium salt and potassium salt, and lower alkanolamine salts. Preferably, the salt is a sodium salt or a potassium salt.

[0014] Specific examples of the N-acyl aspartate used in the detergent composition of the present invention include Na lauroyl aspartate, Na myristoyl aspartate, Na oleoyl aspartate, and the like. In the detergent composition of the present invention, these N-acyl aspartates may be used alone or in combination of two or more.

[0015] In the detergent composition of the present invention, the blending amount of component (B) is preferably 0.5% by mass or more and 7% by mass or less, more preferably 1.5% by mass or more and 4% by mass or less, based on the total amount of the detergent composition. If the blending amount of component (B) is 0.5% by mass or more, the skin after washing can have a moist feeling. If the blending amount of component (B) is 7% by mass or less, a fine foam quality can be obtained. When two or more kinds of component (B) are used in combination, the blending amount of component (B) is the total of them.

[0016] <Component (C) N-acyl methyl taurine salt> Component (C) used in the detergent composition of the present invention is an N-acylmethyltaurine salt. By blending component (C), the foam quality becomes finer, thereby imparting good foam quality (elasticity). Such an acyl group is preferably a fatty acid residue having 8 to 22 carbon atoms. For example, a single acyl group such as lauric acid, myristic acid, palmitic acid, stearic acid, isostearic acid, oleic acid, an acyl group derived from coconut oil fatty acid, beef tallow fatty acid, castor oil fatty acid, olive oil fatty acid, palm oil fatty acid, or a mixture thereof can be mentioned.

[0017] Specific examples of the N-acylmethyltaurine salt used in the detergent composition of the present invention include sodium lauroylmethyltaurine, sodium myristoyl methyltaurine, magnesium lauroylmethyltaurine, and the like. In the detergent composition of the present invention, these N-acylmethyltaurine salts may be used alone or in combination of two or more.

[0018] In the detergent composition of the present invention, the blending amount of component (C) is preferably 0.5% by mass or more and 7% by mass or less, more preferably 1.5% by mass or more and 4% by mass or less, based on the total amount of the detergent composition. If the blending amount of component (C) is 0.5% by mass or more, the foam can be made sufficiently fine. If the blending amount of component (C) is 7% or less, the stability over time can be made good and the generation of precipitates can be suppressed. When two or more kinds of component (C) are used in combination, the blending amount of component (C) is the total of them.

[0019] <Component (D) Amidosulfobetaine-type Amphoteric Surfactant> Component (D) used in the detergent composition of the present invention is an amidosulfobetaine-type amphoteric surfactant. By blending component (D), the feeling of skin tightness after washing can be further reduced, and itching due to drying can be suppressed.

[0020] In the detergent composition of the present invention, the blending amount of component (D) is preferably 1% by mass or more and 9% by mass or less, more preferably 2% by mass or more and 6% by mass or less, based on the total amount of the detergent composition. If the blending amount of component (D) is 2% or more, the feeling of roughness on the skin after washing can be suppressed. If the blending amount of component (D) is 10% or less, a moist feeling can be obtained without feeling stickiness on the skin after washing. When two or more kinds of component (D) are used in combination, the blending amount of component (D) is the total of them.

[0021] In addition to the itching-suppressing effect by anti-inflammation of component (A), the detergent composition of the present invention can improve the elasticity of foam by containing components (B) to (D) and making the foam quality, particularly the foam, finer, and can suppress the itching of the skin induced by irritation by protecting the skin from the frictional irritation generated during skin washing.
