Description

Technical Field

[0001] The present invention relates to a composition.

Background Art

[0002] Conventionally, cosmetics such as shampoos, body soaps, hand soaps, etc., household detergents for dishes, clothes, etc., and daily necessities such as mouthwash and toothpaste contain various surfactants such as nonionic, anionic, and amphoteric surfactants. These surfactants are selected according to their functions such as detergency, usability such as foaming and viscosity suitable for use, and sensory properties such as smoothness during rinsing, according to their purposes and uses, and are used in combination.

[0003] So far, anionic surfactants such as sulfuric acid-based and olefin sulfonic acid-based surfactants having high foaming properties, detergency, and appropriate viscosity have been widely used. However, in cosmetics directly applied to hair and skin, due to the increasing interest in scalp and skin care, cosmetics using amino acid-based surfactants with low irritation as anionic surfactants are becoming popular, and furthermore, the development of cosmetics labeled "sulfate-free" is also underway.

[0004] Amino acid-based surfactants are surfactants with low irritation that have a cleaning action without hurting the skin and hair compared to conventional anionic surfactants, and furthermore, they are considered to be useful as environmentally friendly and sustainable surfactants because they are manufactured using raw materials of natural raw materials (for example, see Patent Document 1). So far, technologies using amino acid-based surfactants have been studied. For example, a thickening composition containing an amino acid-type surfactant and a specific (meth)acrylic acid-based copolymer (for example, see Patent Document 2), or a skin cleansing agent composition containing at least one selected from specific fatty acid salts, 2-ethylhexyl glyceryl ether, and fatty acid esters having a fatty acid residue with 4 to 10 carbon atoms, and an N-acyl amino acid-based surfactant in specific contents and specific ratios (for example, see Patent Document 3) have been proposed.

[0005] As described above, there is a need to develop new compositions using amino acid-based surfactants that maintain conventional functions while considering factors such as irritation and environmental impact. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Special Publication No. 2019-500419 [Patent Document 2] Japanese Patent Publication No. 2014-088348 [Patent Document 3] Japanese Patent Publication No. 2014-231481 [Overview of the project] [Problems that the invention aims to solve]

[0007] However, the technologies described in Patent Documents 1 to 3 did not address the occurrence of turbidity and solidification over time in compositions containing cocoyl glycine or its salts, which are amino acid-based surfactants. As mentioned above, the long-term stability of compositions containing cocoyl glycine or its salts was not considered.

[0008] Therefore, the present invention relates to cocoyl glycine or its salt, and lauryldimethylaminoacetic acid betaine. The objective is to provide a composition containing lauroyl methylalanine or a salt thereof that exhibits excellent stability over time.

[0009] Another objective of the present invention is to provide a composition that is excellent in both foaming ability and foam retention. [Means for solving the problem]

[0010] The inventors investigated the development of a composition that exhibits excellent foaming and foam retention without containing sulfuric acid-based or olefin sulfonate-based surfactants, and found that cocoyl glycine or its salts, used in body soaps and facial cleansers, exhibited excellent effects. However, compositions containing cocoyl glycine or its salts showed signs of clouding and solidification over time, indicating room for improvement. Therefore, after investigating combinations of surfactants, the inventors found that by including lauryldimethylaminoacetic acid betaine and lauroyl methylalanine or its salts in specific ratios, clouding and solidification over time were suppressed, resulting in a composition that was stable enough to maintain a transparent to translucent appearance. Furthermore, the inventors discovered that this composition also exhibited excellent foaming and foam retention, thus completing the present invention.

[0011] In other words, the present invention is as follows. [1] The following components (A) to (C); (A) Lauryldimethylaminoacetic acid betaine (B) Lauroyl methylalanine or its salt (C) Cocoyl glycine or its salt The composition contains such that the mass ratio of component (C) to the total content of component (A) and component (B) (C) / {(A)+(B)} is 0.60 or less. [2] The composition described in [1] above is substantially free of sulfate-based surfactants and / or olefin sulfonate-based surfactants. [3] Furthermore, the composition according to [1] or [2] contains component (D) an amino acid-based surfactant (excluding components (B) and (C)). [4] The composition described in [3] contains two or more of the aforementioned component (D). [5] Furthermore, the composition is one of the above [1] to [4], which contains component (E) an amphoteric surfactant (excluding component (A)). [6] The composition according to any one of [1] to [5], having a pH of 5.0 to 6.0 at 25°C. [7] The composition according to any one of [1] to [6], wherein the composition is a cleaning composition. [8] The composition according to any one of [1] to [7], wherein the composition is a composition for keratin. [9] The composition according to [8], wherein the composition is a composition for hair.

[10] The composition according to any one of [7] to [9], wherein the composition is a hair cleansing cosmetic.

[0021] The component (C) cocoyl glycine or its salt used in the present invention is a condensate of coconut oil fatty acid and glycine, or its salt, and is a type of amino acid-based surfactant.

[0022] The salts in component (C) include, for example, alkali metals such as sodium and potassium, alkaline earth metals such as calcium and magnesium, or organic amines such as ammonia, monoethanolamine, diethanolamine, and triethanolamine, or basic amino acids such as arginine and lysine. Furthermore, the cocoyl glycine salt in component (C) may be a pre-formed salt or a salt produced by a neutralization reaction during manufacturing. Among these salts, potassium salts are preferred as the salt in component (C).

Furthermore, it is preferably 0.1 to 12%, more preferably 0.5 to 10%, even more preferably 1.5 to 8%, and even more preferably 3 to 6%. These ranges are preferable because they result in better foaming and foam retention.

[0031] In the present invention, while maintaining stability over time, the foaming ability and foam retention can be further improved by including component (E) an amphoteric surfactant (excluding component (A)). Furthermore, by including component (E) in the composition, it is possible to adjust the viscosity of the composition not only through its cleaning effect but also by using it in combination with components (B) and (C). The amphoteric surfactant component (E) used in the present invention refers to a surfactant that possesses both cationic and anionic groups. Such component (E) is not particularly limited as long as it is commonly used in ordinary cosmetics, household detergents, and daily necessities. For example, as a carbobetine-type amphoteric surfactant, it may include coconut oil fatty acid amidopropyl betaine, octyldimethylaminoacetic acid betaine, lauric acid amidopropyl betaine, coconut oil fatty acid alkyldimethylaminoacetic acid betaine, myristyldimethylaminoacetic acid betaine, cetyldimethylaminoacetic acid betaine, coconut oil fatty acid amidopropyl dimethylaminoacetic acid betaine, and lauric acid amidopropyl dimethylaminoacetic acid betaine.

One or more of these can be used as needed. Of these, carbobetine-type amphoteric surfactants are preferred from the viewpoint of good foam retention, and coconut oil fatty acid amidopropyl betaine (cocamidopropyl betaine) and lauric acid amidopropyl betaine (lauramidopropyl betaine) are particularly preferred. Commercial products such as Rikabion B-200 (manufactured by Shin Nippon Rika Co., Ltd.) and Rikabion B-300 (manufactured by Shin Nippon Rika Co., Ltd.) can be used.

[0032] The content of component (E) in the present invention is not particularly limited, but it is preferably 0.1% or more, more preferably 0.5% or more, even more preferably 1% or more, and even more preferably 2% or more. Also, it is preferably 10% or less, more preferably 7% or less, even more preferably 5% or less, and even more preferably 4% or less. Also, it is preferably 0.1 to 10%, more preferably 0.5 to 7%, even more preferably 1 to 5%, and even more preferably 2 to 4%. These ranges are preferable because they result in better foaming and foam retention.

[0033] The pH of the composition in this invention is not particularly limited, but is preferably 5.0 to 6.0 at 25°C, and more preferably 5.5 to 6.0. This range is preferable because it provides better stability over time and better foaming. In this application, the pH was measured at 25°C, and a glass electrode type hydrogen ion concentration meter (manufactured by Horiba, Ltd.) was used for the measurement.

[0034] Furthermore, in the present invention, by including components (A) to (C) and component (E), the effects of the present application can be achieved without specifying a particular range for the mass ratio of (C) / {(A)+(B)}.

[0035] In the present invention, although the product can be obtained by appropriately including components (A) to (C) and component (E), specifying the mass ratio of components (A) to (C) is preferable because it can be expected to have a higher effect in terms of stability over time, good foaming, and good foam retention. The mass ratio of (C) / {(A)+(B)} is not particularly limited, but is preferably 0.65 or less, more preferably 0.60 or less, even more preferably 0.55 or less, and even more preferably 0.50 or less. The lower limit of the mass ratio of (C) / {(A)+(B)} is not particularly limited because it is preferable that components (A) and (B) are in excess relative to component (C) cocoyl glycine or its salt, thereby improving stability over time, good foaming, and good foam retention, but is usually 0.10 or more.
