Description

The present invention relates to a cleaning composition and a cleaning product for cleaning hair, etc.

Polyoxyethylene alkyl ether acetic acid is low in irritation to the skin and is suitable as an anionic surfactant to be incorporated into a cleaning composition for washing hair or the body. Such a cleaning composition may contain a nonionic surfactant, an amphoteric surfactant, a cationic polymer, or the like, for the purpose of improving foaming, foam stability, and ease of running through hair when rinsing. For example, Patent Document 1 discloses that a hair cleansing composition contains sodium polyoxyethylene lauryl ether acetate together with coconut oil fatty acid N-methylethanolamide, coconut oil fatty acid amidopropyl dimethylaminoacetic acid betaine, and 0-[2-hydroxy-3-(trimethylammonio)propyl]hydroxyethylcellulose chloride or O-[2-hydroxy-3-(trimethylammonio)propyl]guar gum chloride (see Table 1 in Reference 1).

However, when a cleaning composition is stored, the composition may turn yellow. This yellowing may give a bad impression to the user, even if it does not affect the quality of the cleaning composition when actually used. In particular, when the container is transparent, the color of the cleaning composition contained therein is visible, which may call into question the quality. Therefore, a proposal to suppress the yellowing of cleaning compositions is desired.

In view of the above circumstances, the present invention aims to provide a cleaning composition that can inhibit the progression of yellowing during storage, and a cleaning product that contains the composition.

As a result of intensive research, the present inventors have found that yellowing occurs when polyoxyethylene alkyl ether acetic acid and/or a salt thereof is combined with fatty acid N-methylethanolamide, fatty acid diethanolamide, fatty acid amidopropyl dimethylaminoacetic acid betaine, alkyl dimethylaminoacetic acid betaine, cationized cellulose, cationized guar gum, and/or cationized cassia, and that the combination of pyrosulfite, sulfite, acetylcysteine, and/or dibutylhydroxytoluene is suitable for suppressing this yellowing, leading to the completion of the present invention.

That is, the cleaning composition according to the present invention is characterized in that it contains the following components (A), (B), and (C). The composition is used, for example, for cleaning hair.
(A) polyoxyethylene alkyl ether acetic acid and/or its salt; (B) fatty acid N-methylethanolamide, fatty acid diethanolamide, fatty acid amidopropyl dimethylaminoacetic acid betaine, alkyl dimethylaminoacetic acid betaine, cationized cellulose, cationized guar gum and/or cationized cassia; (C) pyrosulfite, sulfite, acetylcysteine and/or dibutylhydroxytoluene.

In the cleaning composition of the present invention, for example, the amount of component (A) is 2% by mass or more. Even if the amount of component (A) is 2% by mass or more, the progression of yellowing can be suppressed by adding component (C).

In the cleaning composition of the present invention, it is preferable that the amount of component (B) is less than 10% by mass. If the amount of component (B) is less than 10% by mass, it is suitable for suppressing yellowing.

In the cleaning composition of the present invention, for example, the fatty acid N-methylethanolamide and the fatty acid diethanolamide are blended in an amount of 3.0 mass% or more. Even if the fatty acid N-methylethanolamide and the fatty acid diethanolamide are blended in an amount of 3.0 mass% or more, the progression of yellowing is suppressed by blending component (C).

In the cleaning composition of the present invention, it is preferable that the fatty acid N-methylethanolamide and the fatty acid diethanolamide are blended in an amount of less than 3.0% by mass, or that they are not blended at all. If the fatty acid N-methylethanolamide and the fatty acid diethanolamide are blended in an amount of less than 3.0% by mass, or that they are not blended at all, this is suitable for suppressing yellowing.

In the cleaning composition of the present invention, for example, the fatty acid amidopropyl dimethylamino acetic acid betaine and the alkyl dimethylamino acetic acid betaine are blended in an amount of 3.0% by mass or more. Even if the fatty acid amidopropyl dimethylamino acetic acid betaine and the alkyl dimethylamino acetic acid betaine are blended in an amount of 3.0% by mass or more, the progression of yellowing is suppressed by blending component (C).

In the cleaning composition of the present invention, it is preferable that the fatty acid amidopropyl dimethylamino acetic acid betaine and the alkyl dimethyl amino acetic acid betaine are blended in an amount of less than 3.0% by mass, or that they are not blended at all. If the fatty acid amidopropyl dimethyl amino acetic acid betaine and the alkyl dimethyl amino acetic acid betaine are blended in an amount of less than 3.0% by mass, or that they are not blended at all, this is suitable for suppressing yellowing.

In the cleaning composition of the present invention, for example, the cationic cellulose, the cationic guar gum, and the cationic cassia are blended in an amount of 0.5% by mass or more. Even if the cationic cellulose, the cationic guar gum, and the cationic cassia are blended in an amount of 0.5% by mass or more, the progression of yellowing is suppressed by blending component (C).

In the cleaning composition of the present invention, the cationic cellulose, the cationic guar gum, and the cationic cassia are preferably blended in an amount of less than 0.5% by mass, or are not blended at all. If the cationic cellulose, the cationic guar gum, and the cationic cassia are blended in an amount of less than 0.5% by mass, or are not blended at all, this is suitable for suppressing yellowing.

The cleaning product according to the present invention is characterized by comprising the cleaning composition according to the present invention and a transparent container for containing the cleaning composition.

In the cleaning composition according to the present invention, the progression of yellowing caused by component (A) polyoxyethylene alkyl ether acetic acid and/or its salt and component (B) fatty acid N-methylethanolamide, fatty acid diethanolamide, fatty acid amidopropyl dimethylaminoacetic acid betaine, alkyl dimethylaminoacetic acid betaine, cationized cellulose, cationized guar gum, and/or cationized cassia is suppressed by pyrosulfite, sulfite, acetylcysteine, and/or dibutylhydroxytoluene.

The cleaning product of the present invention also prevents the contained cleaning composition from yellowing, eliminating unnecessary doubts about its quality.

The present invention will be described in detail below with reference to examples, but the present invention should not be construed as being limited to the descriptions in these examples.

(Examples 1a to 1b, Comparative Examples 1a to 1b)
The transparent liquid cleaning compositions of Examples 1a to 1b and Comparative Examples 1a to 1b were produced by blending components selected from sodium polyoxyethylene lauryl ether acetate (a combination of sodium polyoxyethylene lauryl ether acetate with an average ethylene oxide molar number of 4.5 and a combination of sodium polyoxyethylene lauryl ether acetate with an average ethylene oxide molar number of 10), coconut oil fatty acid amidopropyl dimethylaminoacetate betaine, coconut oil fatty acid N-methylethanolamide, O-[2-hydroxy-3-(trimethylammonio)propyl]hydroxyethylcellulose chloride, sodium sulfite, acetylcysteine, cysteine, sodium tetradecene sulfonate, coconut oil fatty acid sodium methyl taurate, sodium benzoate, and phenoxyethanol with water. The concentrations of the components blended with water in this production are as shown in Table 1 below. In addition, appropriate amounts of citric acid and sodium hydroxide were blended to adjust the pH of each cleaning composition to 5.0 to 6.0.

The yellowing of the cleaning compositions of Examples 1a to 1b and Comparative Examples 1a to 1b was confirmed as follows. Each cleaning composition was poured into a transparent vial (height 12 cm, diameter approximately 4 cm) and the container was sealed. It was then left to stand for 23 days at a temperature of 60°C. The degree of yellowing was then confirmed, based on the level of coloration in Comparative Example 1a.

Table 1 below shows the results of confirming yellowing for the cleaning compositions of Examples 1a-1b and Comparative Examples 1a-1b, as well as the components and their concentrations that were mixed with water. In Table 1, "○" means that yellowing was suppressed more than the standard, "◎" means that yellowing was suppressed more than "○", and "×" means that yellowing was more severe than the standard. In other words, Table 1 confirms that acetylcysteine suppressed yellowing, and that sodium sulfite, a sulfite, suppressed yellowing even more.

(Examples 2a to 2c)
The transparent liquid cleaning compositions of Examples 2a to 2c were produced by blending components selected from sodium polyoxyethylene lauryl ether acetate (a combination of sodium polyoxyethylene lauryl ether acetate with an average ethylene oxide molar number of 4.5 and a combination of sodium polyoxyethylene lauryl ether acetate with an average ethylene oxide molar number of 10), coconut oil fatty acid amidopropyl dimethylaminoacetate betaine, coconut oil fatty acid N-methylethanolamide, O-[2-hydroxy-3-(trimethylammonio)propyl]hydroxyethylcellulose chloride, sodium sulfite, sodium hydrogensulfite, sodium pyrosulfite, sodium tetradecene sulfonate, coconut oil fatty acid sodium methyl taurate, sodium benzoate, and phenoxyethanol with water.

Each cleaning composition was poured into a transparent vial (height 12 cm, diameter approximately 4 cm) and the container was sealed. It was then left to stand at a temperature of 60°C for 30 days. The degree of yellowing was then confirmed based on the standard of Example 2a.

Table 2 below shows the results of checking yellowing for the cleaning compositions of Examples 2a to 2c, as well as the components and their concentrations that were mixed with water. The "◎" in Table 2 means that yellowing was suppressed more than the standard "○". In other words, Table 2 confirms that sodium pyrosulfite, a pyrosulfite, suppressed yellowing more than sodium sulfite and sodium hydrogensulfite, which are sulfites.

(Examples 3a to 3b)
The transparent liquid cleaning compositions of Examples 3a to 3b were produced by blending sodium polyoxyethylene lauryl ether acetate (a combination of sodium polyoxyethylene lauryl ether acetate with an average ethylene oxide molar number of 4.5 and a combination of sodium polyoxyethylene lauryl ether acetate with an average ethylene oxide molar number of 10), coconut oil fatty acid amidopropyl dimethylaminoacetate betaine, coconut oil fatty acid N-methylethanolamide, O-[2-hydroxy-3-(trimethylammonio)propyl]hydroxyethylcellulose chloride, sodium pyrosulfite, sodium tetradecene sulfonate, coconut oil fatty acid sodium methyl taurate, sodium benzoate, phenoxyethanol and water. The concentrations of the components blended with water in this production are as shown in Table 3 below. In addition, appropriate amounts of citric acid and sodium hydroxide were blended to adjust the pH of each cleaning composition to 5.0 to 6.0.

The yellowing of the cleaning compositions of Examples 3a and 3b was confirmed in the same manner as in Example 2a. Then, the degree of yellowing was confirmed based on the level of coloring of Example 3a.

Table 3 below shows the results of checking yellowing for the cleaning compositions of Examples 3a to 3b, as well as the components and their concentrations that were mixed with water. In Table 3, "◎" means that yellowing was suppressed more than the standard "○". In other words, Table 3 shows that increasing the amount of component (C) improved yellowing suppression.

(Reference Examples 1a to 1e, Reference Examples 2a to 2f)
