Description

TECHNICAL FIELD This disclosure relates to cleaning compositions. For example, the present disclosure relates to cleansing compositions that can be applied to the skin. The present disclosure also relates to a cleaning product that discharges the cleaning composition using a pump former.

BACKGROUND ART Pump-type containers are popular as containers for cleaning agents and the like. There are two types of pump-type containers: one type that discharges the liquid contents as is, and the other type that manually foams the cleaning agent and discharges it (pump former). For example, Patent Document 1 discloses a liquid detergent or a liquid cosmetic to be filled into a pump-type container. The liquid cleaning agent or liquid cosmetic for filling containers described in Patent Document 1 contains 12-hydroxystearic acid as a solidification inhibitor that suppresses solidification of the liquid at the discharge port of the pump.

The latter pump former usually incorporates a mesh for foaming the cleaning agent. However, if the cleaning agent solidifies or dries in this mesh, it will become clogged. Therefore, cleaning compositions that suppress the occurrence of clogging have been developed (for example, Patent Document 2). The cleaning composition described in Patent Document 2 includes a soap obtained by neutralizing a higher fatty acid having 14 or less carbon atoms with sodium N-methyltaurate, and a soap having a molecular weight of 100,000 or more and containing dimethyldiallylammonium chloride as a monomer unit. Contains a polymer.

Japanese Patent Application Publication No. 9-48962 WO2019/059111A1 publication

The following analysis is given in light of this disclosure.

The mesh size of the pump former is much smaller than the pump discharge port. For this reason, it is more difficult to suppress clogging in the pump former than to suppress solidification of liquid at the discharge port of the pump as described in Patent Document 1. Further, in Patent Document 2, a polymer having a molecular weight of 100,000 or more is blended. It is presumed that the larger the molecular weight of the polymer, the more easily the mesh of the pump former becomes clogged. For this reason, it is expected that methods for improving clogging and foam quality without using high molecular weight polymers will be investigated.

On the other hand, when attempting to suppress clogging in the mesh of the pump former, the foam quality such as elasticity and sustainability of the foam discharged from the pump tends to deteriorate. That is, in general, there is a trade-off relationship between preventing clogging in the pump former and achieving good foam quality. Therefore, there is a need for a cleaning composition that achieves both prevention of clogging and good foam quality.

According to the first aspect of the present disclosure, it contains (A) a higher fatty acid that does not have a hydroxy group, (B) a higher fatty acid that has at least one hydroxy group, and (C) an N-methyltaurine salt. A cleaning composition is provided.

The cleaning composition of the present disclosure can be applied to a pump former. In the cleaning composition of the present disclosure, clogging in the pump former (particularly in the mesh portion) is suppressed. The foam formed from the cleaning composition of the present disclosure discharged from the pump former can have high elasticity and sustainability.

The foam of the cleaning composition of the present disclosure discharged from the pump former has good foam persistence. Additionally, the foam of the cleaning composition of the present disclosure has high elasticity. Thereby, the user can obtain a good feeling when cleaning. Moreover, after washing the skin with the foam of the cleansing composition of the present disclosure, the user can feel a moist feeling (moist feeling) on the skin.

The cleaning composition of the present disclosure can suppress the occurrence of solidification and clogging in a pump type container. In particular, the cleaning composition of the present disclosure can suppress the occurrence of clogging due to solidification in the mesh portion of a pump former having a mesh.

The cleaning composition of the present disclosure can be suitably applied to, for example, a cosmetic removal cleaning agent, a hand soap, a body soap, a hair cleaning agent, a kitchen cleaning agent, and the like.

A method for manufacturing the cleaning composition of the present disclosure will be described. The cleaning composition of the present disclosure can be produced by a generally known method without any particular method. For example, a cleaning composition can be prepared by mixing the above components.

The fatty acid taurine salt, which is a complex of component (A), component (B), and component (C), is preferably produced in advance and then added to the composition. For example, a fatty acid taurine salt can be prepared by dissolving components (A) and (B) in water by heating and adding component (C) to an aqueous solution of components (A) and (B). By adding the fatty acid taurine salt prepared in advance in this way, the cleaning composition of the present disclosure can be manufactured.

In some cases, the behavior of each component in a cleaning composition is unclear. For example, component (A), component (B), and component (C) are considered to form a fatty acid taurine salt, but what is the structure or structure of component (A), component (B), and component (C)? It is difficult or often impractical to directly determine what behavior is being adopted. Therefore, if the cleaning composition of the present disclosure cannot be directly identified by its composition, it should be allowed to be described by its manufacturing method.

A cleaning product according to a second embodiment of the present disclosure will be described. A cleaning product of the present disclosure includes the cleaning composition according to the first embodiment and a container containing the cleaning composition.

Regarding the cleaning composition according to the first embodiment, the above description is cited.

The container can be a pump container. The pump-type container may be one that discharges the liquid cleaning composition as it is, or may be one that discharges it in the form of foam (pump former, foaming pump). The pump former may be one that manually foams the cleaning composition or may be one that foams the cleaning composition using high-pressure gas.

The pump former can have a mesh for foaming the cleaning composition. For example, in a manual pump former, a discharge nozzle installed at the top of the container that discharges the cleaning agent composition is pushed toward the container, and the cleaning agent composition is passed together with air through a mesh provided inside the nozzle. The cleaning composition may be discharged in the form of foam.

In the cleaning product of the present disclosure, clogging due to solidification of the cleaning composition is suppressed. In particular, even in a pump former having a mesh, clogging in the mesh portion is suppressed.

A method of using the cleaning composition according to the third embodiment of the present disclosure will be described. The cleaning composition according to the first embodiment can be used by being discharged from a pump-type container (particularly a pump former) as described above. As a result, it is possible to form a foam that is durable and has elasticity. Further, by using the cleaning composition according to the first embodiment, it is possible to suppress clogging in the mesh portion of the pump former. Furthermore, a good feeling of use can be obtained after washing.

The cleaning composition and cleaning product of the present disclosure will be described below using examples. However, the cleaning composition of the present disclosure is not limited to the following examples. Further, in the following Examples, an example will be described in which the cleaning composition of each test example is applied to cleaning cosmetics, but the composition of the present disclosure is not limited to use in cosmetics. The unit of content of each component shown in each table is mass %.

[Test Examples 1 to 6]
A cleaning composition was prepared and placed in a manual pump former. Then, the foam of the cleaning composition was discharged from the pump former, and the discharged foam was evaluated according to the following criteria. The pump former used is a commonly used type that has a mesh inside the nozzle and manually pushes the nozzle into the container from top to bottom to expel foam from the nozzle. Table 1 shows the composition and evaluation of each composition. The items shown in the table were evaluated based on the criteria shown below.

[Occurrence of blockage]
A cleaning composition was placed in a manual pump former having a mesh, and the foamed cleaning composition was discharged several times from the pump former, and then the pump former was dried in a thermostat at 50°C for one week. Thereafter, when the cleaning composition was again discharged from the pump former, it was evaluated whether or not the mesh was clogged. This evaluation test was conducted on five samples for each cleaning composition.
A: Out of the 5 samples, no clogging occurred;
B: Clogging occurred in one or more of the 5 samples.

[Sustainability of foam]
When the cleansing composition was discharged from a pump former and the face to which cosmetics had been applied was washed with the discharged foam, the sustainability of the foam was confirmed:
A: The foam lasts much longer than the foam in Test Example 1;
B: The foam lasts longer than the foam in Test Example 1;
C: The persistence of foam was the same as in Test Example 1;
D: The foam collapsed more easily than the foam in Test Example 1;
E: The foam collapsed more quickly than the foam in Test Example 1.

[Foam elasticity]
The cleaning composition was discharged from the pump former, and the elasticity of the discharged foam was checked by pressing with a finger:
A: The foam had stronger elasticity than the foam of Test Example 1;
B: The foam had slightly stronger elasticity than the foam of Test Example 1;
C: The elasticity was equivalent to that of the foam of Test Example 1;
D: The elasticity of the foam was weaker than that of Test Example 1;
E: The elasticity of the foam was much weaker than that of Test Example 1.

[Feeling after washing]
Eight panelists were asked to cleanse their skin with the cleansing composition and check the feel of their skin after rinsing:
A: It had a better moist feeling than the foam of Test Example 1;
B: Moist feeling equivalent to the foam of Test Example 1;
C: It felt less moist than the foam of Test Example 1.

The cleaning composition of Test Example 1 contains neither component (A3) stearic acid nor component (B) 12-hydroxystearic acid, and is used as a comparison control. In Test Example 2, in which component (A3) stearic acid was added to Test Example 1, the foam quality was improved, but the pump was clogged. In Test Example 3 in which the amount of component (A3) added was increased, some components did not dissolve. Although the long-chain component (A3) improved the foam quality, it is thought that the solubility decreased, resulting in clogging. From this, it is considered that the carbon number of component (A) higher fatty acid is preferably 16 or less.

On the other hand, in Test Example 4 in which 1% by mass of component (B) 12-hydroxystearic acid was added instead of component (A3), the foam quality was improved and no clogging was observed. Therefore, it was found that by adding component (B), both improvement in foam quality and prevention of clogging can be achieved. From this, it was found that component (B) can be a higher fatty acid having 18 or more carbon atoms and having a hydroxyl group. When the content of component (B) was 2% by mass or more, clogging occurred in Test Example 5, and the composition gelled in Test Example 6. From this, it is considered that the content of component (B) is preferably 0.1% by mass or more, and more preferably 0.5% by mass or more, based on the mass of the composition. Moreover, it is considered that the content of component (B) is preferably 1.8% by mass or less, and more preferably 1.6% by mass or less, based on the mass of the composition. It is considered that the amount of component (A) is preferably 2.5 parts by mass or more, and more preferably 3 parts by mass or more, per 1 part by mass of component (B). Further, it is considered that the amount of component (A) is preferably 5.5 parts by mass or less, and more preferably 5 parts by mass or less, per 1 part by mass of component (B).

[Test Examples 7 to 14]
We tested the effect of neutralization rate on foam quality, etc. Tables 2 and 3 show the composition and evaluation of each composition. The evaluation method and evaluation criteria are the same as Test Examples 1 to 6.

In Test Examples 7 to 10 in which component (A3) was added, clogging occurred similarly to Test Examples 2 and 5, regardless of the neutralization rate. On the other hand, in Test Examples 11 to 14 in which 1% by mass of component (B) was added, the same results as Test Example 4 were obtained regardless of the neutralization rate. Therefore, it is considered that the neutralization rate may be any value as long as it is within the range of at least 70% to 130%.
