This international application claims priority based on Japanese Patent Application No. 2020-21642 filed with the Japan Patent Office on February 12, 2020, and Japanese Patent Application No. 2020-21642. The entire contents are incorporated in this international application by reference.

The present disclosure relates to a detergent composition.

Preservatives such as paraben, benzoic acid, and salicylic acid are used in cosmetics such as detergent compositions. However, these preservatives may have an upper limit on the concentration used from the viewpoint of safety such as irritation.

As an alternative preservative, Patent Document 1 describes 1,2-alkanediol having 5 to 10 carbon atoms and the like.

Japanese Patent No. 3625214

However, according to the study of the present inventor, when the above-mentioned preservatives such as alkanediol are mainly applied to the detergent composition, foaming and the feel of the skin or hair at the time of washing are not good, and the product is used. It turned out that the feeling may not be good.

One aspect of the present disclosure is to provide a detergent composition having high antiseptic properties and excellent usability.

One aspect of the present disclosure is a detergent composition containing (A) at least one of polyhydric alcohols and saccharides, (B) anionic surfactant, and (C) amphoteric surfactant. do. The heat of fusion of the frozen detergent composition is 130 mJ / mg or less, and the total content of the components (B) and (C) in the detergent composition is 10% by mass or more.

In one aspect of the present disclosure, the content of the component (A) in the detergent composition may be 20% by mass or more, and the content of the component (A) in the detergent composition is the detergent composition. It may be larger than the total content of the component (B) and the component (C) in the mixture.

In one aspect of the present disclosure, the component (A) may contain at least one of (A1) polyhydric alcohols and saccharides having an IOB value of 3.5 or higher, and (A) in the detergent composition. The ratio of the content of the component (A1) in the detergent composition to the content of the component may be 0.7 or more.

In one aspect of the present disclosure, the detergent composition may be used by being discharged in a liquid state and foamed.

According to one aspect of the present disclosure, a detergent composition having high antiseptic properties and excellent usability is provided.

The detergent composition of one aspect of the present disclosure contains at least one of (A) polyhydric alcohols and saccharides, (B) anionic surfactant, and (C) amphoteric surfactant. The heat of fusion of the frozen detergent composition is 130 mJ / mg or less, and the total content of the components (B) and (C) in the detergent composition is 10% by mass or more.

As described below, such a cleaning agent composition has high antiseptic properties and is excellent in usability.

The water contained in the detergent composition is roughly divided into bound water and free water according to the state. The bound water refers to water bound to other components in the detergent composition by hydrogen bonds or the like. On the other hand, free water refers to water that can move around freely without being bound by other components in the detergent composition. Of these, the water that can be used by microorganisms is free water, so if the content of free water is high, microorganisms are likely to grow.

The present inventor paid attention to the heat of fusion of the detergent composition as a parameter indicating the content of free water in the detergent composition. Free water freezes at 0 ° C or lower like simple water. On the other hand, since the bound water is retained by other components contained in the detergent composition, it is presumed that the bound water exists without freezing even at 0 ° C. or lower. Therefore, the heat of fusion of the detergent composition is considered to reflect the content of free water in the detergent composition. Therefore, it can be said that the lower the heat of fusion of the detergent composition, the smaller the content of free water in the detergent composition, and the higher the antiseptic property of the detergent composition.

Here, the component (A) interacts with water to reduce the content of free water in the detergent composition and improve the antiseptic property of the detergent composition. However, according to the study of the present inventor, it has been found that the detergent composition containing the component (A) may not have good foaming. In particular, in order to achieve the desired heat of fusion, it is preferable to contain the component (A) in a relatively large amount, and in that case, the foaming of the detergent composition tends to decrease.

On the other hand, by using the component (B) and the component (C) in combination and making the total content of the component (B) and the component (C) 10% by mass or more, a low heat of fusion can be achieved. It was found that good foaming can be obtained while achieving a heat of fusion of 130 mJ / mg or less.

Hereinafter, the detergent composition of one aspect of the present disclosure will be described in detail.

[(A) component]
The component (A) reduces the content of free water in the detergent composition and improves the antiseptic property of the detergent composition. In addition, the component (A) also has a property of improving the feel of the skin or hair at the time of washing. For example, when the detergent composition is shampoo, the component (A) improves the flexibility of the hair when it is washed away. The improvement of the flexibility of the hair at the time of rinsing here means a state in which a moist feeling is given to the hair and the squeaky feeling, the tightness feeling, etc. of the hair are suppressed. In addition, since the component (A) is less irritating than preservatives such as paraben, benzoic acid, and salicylic acid, a mild detergent composition can be obtained as compared with the case of using these.

Specific examples of the polyhydric alcohols in the component (A) include a compound in which two or more hydrogen atoms of an aliphatic hydrocarbon are replaced with a hydroxy group, and two hydrogen atoms of an aliphatic hydrocarbon are replaced with a hydroxy group. Examples thereof include a dimer obtained by dehydration condensation of a compound glycol (for example, ethylene glycol, propylene glycol, etc.). Specific examples of the saccharide in the component (A) include monosaccharides, disaccharides, polysaccharides, liquid sugars, sugar alcohols and the like. In the present disclosure, the sugar alcohol refers to a sugar-derived compound produced by reducing the carbonyl group of aldose.

The detergent composition preferably contains at least one of the polyhydric alcohols and sugars having an IOB value of 3.5 or more among the components (A). Hereinafter, polyhydric alcohols or saccharides having an IOB value of 3.5 or more are referred to as a component (A1), and polyhydric alcohols or saccharides having an IOB value of less than 3.5 are referred to as a component (A2). According to the study of the present inventor, it has been found that the component (A1) is less likely to cause a decrease in foaming of the detergent composition than the component (A2).

Here, IOB is an abbreviation for Organic / Organic Balance (inorganic / organic ratio). The IOB value is a value of the ratio of the inorganic value of the compound to the organic value of the compound, and is an index showing the degree of polarity of the organic compound. Specifically, the IOB value is expressed as an inorganic value / organic value. As for each of the inorganic value and the organic value of the compound, for example, the "organic value" is 20 for one carbon atom in the molecule, the "inorganic value" is 100 for one hydroxyl group, and so on. The "inorganic value" and "organic value" are set according to the functional group, and the "inorganic value" and "organic value" of all the atoms and functional groups in the organic compound are integrated. Calculated (see, for example, Yoshio Koda, "Organic Conceptual Diagram-Basics and Applications-", pp. 11-17, Sankyo Publishing, 1984). The IOB value of an organic compound is calculated using the integrated inorganic value and organic value.

Of these components, one type may be contained alone, or two or more types may be contained in combination.

The detergent composition may contain the component (A1) or the component (A2) alone, or may contain both the component (A1) and the component (A2). However, from the viewpoint of suppressing the decrease in foaming due to the component (A), the detergent composition preferably contains at least the component (A1).

When the detergent composition contains the component (A1), the ratio of the content of the component (A1) in the detergent composition to the total content of the component (A) in the detergent composition "(A1). / (A) ”is preferably 0.7 or more. When (A1) / (A) is 0.7 or more, the foaming of the detergent composition is less likely to decrease, and good foaming can be obtained. (A1) / (A) is more preferably 0.75 or more, still more preferably 0.8 or more.

The content of the component (A) in the detergent composition is preferably 15% by mass or more. When the content of the component (A) is 15% by mass or more, the heat of fusion is lowered, the antiseptic property of the detergent composition is further improved, and the effect of improving the feel of the skin or hair at the time of washing is also high. Specifically, the content of the component (A) is more preferably 20% by mass or more, further preferably 25% by mass or more, still more preferably 30% by mass or more. The content of the component (A) is not particularly limited in the upper limit, but is preferably 90% by mass or less, more preferably 70% by mass or less, and further preferably 50% by mass or less.

Further, the content of the component (A) is preferably larger than the total content of the components (B) and (C) in the detergent composition. This is because the component (A) tends to exert the effect of improving the feel of the skin or hair during washing. In particular, when the content of the component (A) is 20% by mass or more and the content of the component (A) is larger than the total content of the components (B) and (C), the cleaning agent The antiseptic property of the composition is further improved, and the effect of the component (A) on improving the feel of the skin or hair during washing is further improved.

There is. Therefore, these types of cleaning agent compositions are required to have a relatively low viscosity in order to suppress the resistance when passing through the mesh, and as a result, the surfactant contained in the cleaning agent composition. There is a tendency to keep the amount of detergent small. On the other hand, since the detergent composition of the type that is discharged in liquid form and used by foaming does not have such a limitation, the content of the surfactant in the detergent composition can be relatively increased. Therefore, when the above-mentioned cleaning agent composition in the present disclosure is used as a type of cleaning agent composition which is discharged in a liquid state and used by foaming, the contents of the components (B) and (C) which are surfactants are contained. Can be relatively large. Needless to say, the cleaning agent composition in the present disclosure may be used as a cleaning agent composition of a type that is discharged from a former container in the form of a foam.

[Use and usage of detergent composition]
The use of the cleansing composition is not particularly limited, and for example, it can be used as a cleansing composition for hair, a cleansing composition for the body, and the like. Specifically, the detergent composition can be used as, for example, shampoo, body shampoo, face wash, hand soap and the like. Of these, the detergent composition can be suitably used as a detergent composition for hair.

When the cleansing composition is a cleansing composition for hair, the cleansing composition may be applied to wet hair or dry hair. The cleansing composition is preferably applied to wet hair. The method of applying the detergent composition to the hair is not particularly limited, and a known method can be appropriately used. Examples of the coating method include coating with a hand comb, coating with a spray (spray), coating with a comb or a brush, and the like. The detergent composition is whipped according to a conventional method and then washed away with water, hot water or the like.

[Preparation of detergent composition]
The detergent compositions according to Examples 1 to 9 shown in Table 1 below and the detergent compositions according to Comparative Examples 1 to 6 shown in Table 2 below were prepared according to a conventional method. The numerical value indicating the content of each component in Tables 1 and 2 is mass%. DPG in Tables 1 and 2 is an abbreviation for dipropylene glycol.

[Evaluation of detergent composition]
The prepared detergent composition was measured and evaluated as follows.

(Measurement of heat of fusion)
The heat of fusion of the detergent composition was measured using a differential scanning calorimeter (DSC) "DSC6220" (manufactured by SII Nanotechnology, Inc. (currently Hitachi High-Tech Science)). Specifically, the temperature is lowered at a rate of 5 ° C. per minute to cool to −70 ° C. to freeze the cleaning agent composition, and then the temperature is raised at a rate of 5 ° C. per minute to raise the cleaning agent. The composition was thawed. The heat of fusion was calculated based on the endothermic peak attributed to the heat of fusion observed in the obtained DSC curve, that is, the peak area of the endothermic peak having a peak at a temperature of 0 ° C. or lower. The results are shown in Tables 1 and 2.

(Antiseptic)
10 g of the detergent composition was aseptically dispensed into a sterilized vial. By inoculating Aspergillus was preconditioned bacteria count (Aspergillus brasiliensis) a predetermined amount detergent composition was prepared to adjust the test solution so that the number of bacteria is 10 ⁵ cfu / g.

0.1 mL of the obtained test solution was taken and smeared on GPLP agar medium with a spreader to confirm the number of surviving bacteria. The number of surviving bacteria was confirmed 28 days after inoculation of the bacteria. The antiseptic property was evaluated with A as the one in which no bacteria were detected on the agar medium and B as the one without the bacteria. The results are shown in Tables 1 and 2.

(Bubbling)
Twenty panelists washed their hair with the detergent composition. Of the 20 panelists, when the number of panelists who evaluated that the foaming was good when the detergent composition was whipped on the hair was 17 or more, it was evaluated as "very excellent: 5", and 13 to 16 people. Is "excellent: 4", 9 to 12 people are "good: 3", 5 to 8 people are "slightly bad: 2", and 4 or less people are "bad: 1". The foaming was evaluated on a 5-point scale. The results are shown in Tables 1 and 2.

(Feeling when rinsing)
Twenty panelists washed their hair with the detergent composition. Of the 20 panelists, when the number of panelists who evaluated the flexibility of the hair when rinsing was 17 or more, it was rated as "very excellent: 5", and when it was 13 to 16, it was rated as "excellent: 4". , 9 to 12 people are "good: 3", 5 to 8 people are "slightly bad: 2", and 4 or less people are "bad: 1". The feel was evaluated. The results are shown in Tables 1 and 2. The flexibility of the hair at the time of rinsing was judged based on whether or not the hair had a moist feeling and there was no squeaky or taut feeling of the hair.

[Discussion]
In Examples 1 to 9, the antiseptic property was high, and the usability was excellent from the viewpoint of foaming and the feel at the time of rinsing. In particular, comparing Examples 1 to 4, 6 and 7 in which the component (A) is the same, the content of the component (A) is 20% by mass or more, and the content of the component (A) is the component (B). In Examples 3, 4 and 6, which are larger than the total content of the component (C), the effect of improving the feel of the component (A) tends to be higher than in Examples 1, 2 and 7 which are not. Was there. Comparing Examples 3, 8 and 9 containing the same amount of the component (A), Example 3 in which the ratio of the content of the component (A1) to the content of the component (A) is 0.7 or more. , 9 tended to have better foaming than Example 8 which did not.

On the other hand, in Comparative Example 1 containing no component (A), the heat of fusion was not 130 mJ / mg or less, and the antiseptic property and the feel at the time of rinsing were not good. Even in Comparative Example 2 in which the heat of fusion was not 130 mJ / mg or less even though the component (A) was contained, the antiseptic property and the feel at the time of rinsing were not sufficient. Even if the component (A) was contained and the heat of fusion was 130 mJ / mg or less, the foaming was not good in Comparative Example 3 in which the total content of the components (B) and (C) was not 10% by mass or more. .. In Comparative Example 4 in which the heat of fusion is not 130 mJ / mg or less and the total content of the components (B) and (C) is not 10% by mass or more, the antiseptic property, foaming, and feel at the time of rinsing are all good. It wasn't. Further, even if the heat of fusion is 130 mJ / mg or less and the total content of the component (B) and the component (C) is 10% by mass or more, Comparative Example 5 containing only the component (B) and ( C) In Comparative Example 6 containing only the component alone, foaming was not sufficient.
