[0001] The present invention is based on the priority claim of Japanese Patent Application No. 2020-156298 (filed September 17, 2020), the entire contents of which are incorporated herein by reference. [Technical Field]

[0002] The present disclosure relates to cleansing compositions. [Background technology]

[0003] Cream (paste) type cleansers in tube-type containers are in high demand for facial cleansers such as face washes and makeup removers. Cream-type cleansers are described in, for example, Patent Documents 1 and 2.

[0004] Patent Document 1 describes a facial cleansing composition in which palmitic acid accounts for 40% or more of the constituent fatty acids, the neutralization rate of all constituent fatty acids is 70 to 82%, and the composition contains glycerin, with the total amount of fatty acids being 36% by mass.

[0005] Patent Document 2 describes a creamy aqueous cleanser containing 32% or more by mass of higher fatty acids, in which the sum of the contents of myristic acid and palmitic acid relative to the total amount of higher fatty acids is 73% or more by mass, and the mass ratio of myristic acid to palmitic acid is 1:1 to 1:5. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-282591 [Patent Document 2] Japanese Patent Application Laid-Open No. 2011-173841 Summary of the Invention [Problem to be solved by the invention]

[0007] The following analysis is given in light of the present disclosure.

[0008] The cream cleansers described in Patent Documents 1 and 2 contain a large amount of higher fatty acids. However, if the amount of higher fatty acids is too high, foaming will be slow. On the other hand, if the amount of higher fatty acids is too low, the cleanser will not become creamy but will become liquid.

[0009] Furthermore, in high-temperature regions, products may be temporarily exposed to temperatures of 50°C or higher during transportation. In such environments, cream-type cleansers tend to liquefy. Even if the cleanser returns to room temperature (e.g., 30°C or below) after liquefaction, it becomes too hard, making it difficult to dispense from the tube container, or the ingredients may separate, resulting in a loss of uniformity.

[0010] Therefore, there is a demand for a cleanser composition that can foam quickly and maintain its creamy form even when subjected to temperature changes. [Means for solving the problem]

[0011] According to a first aspect of the present disclosure, there is provided a cleanser composition comprising: (A) 22% by mass to 30% by mass of a higher fatty acid; (B) a neutralizing agent for the higher fatty acid; (C) 10% by mass to 30% by mass of a polyhydric alcohol; (D) 1% by mass to 5% by mass of an amphoteric surfactant; and (E) 0.1% by mass to 2% by mass of a salt. The mass proportion of myristic acid in the higher fatty acids is 60 mass % to 1900 / 27 mass %. The mass ratio of stearic acid in higher fatty acids is 7.4% by mass or more It is 12% by mass or less. [Effects of the Invention]

[0012] The cleansing composition of the present disclosure can maintain a uniform paste form even in a high-temperature environment, and can also maintain the cream form it had before being placed in a high-temperature environment even when returned to room temperature.

[0013] The cleansing compositions of the present disclosure are fast lathering. DETAILED DESCRIPTION OF THE INVENTION

[0089] It may be difficult or impractical to directly identify the cleansing composition of the present disclosure by its composition, structure, etc. For example, in the cleansing composition of the present disclosure, components (A) and (B) are considered to form a fatty acid soap, but it may be difficult or impractical to directly identify the structure or behavior of components (A) and (B). Therefore, when the cleansing composition of the present disclosure cannot be directly identified by its composition, etc., it should be permitted to describe it by its manufacturing method. [Example]

[0090] The cleanser composition of the present disclosure will be described below with reference to examples. However, the cleanser composition of the present disclosure is not limited to the following examples. In the following examples, examples in which the cleanser composition of each test example is applied to the cleaning of cosmetics will be described, but the composition of the present disclosure is not limited to use in cosmetics. The content of each component shown in each table is in mass%.

[0091] [Test Examples 1 to 9] Cleansing compositions were prepared and tested for their behavior in response to temperature changes. Table 1 shows the composition and evaluation of each composition. The items shown in the table were evaluated according to the following criteria. Immediately after preparation, the cleansing compositions were creamy. Whether or not they were in a cream (paste) form was determined by observing the appearance and feel of the composition.

[0092] [Low temperature stability] The cleansing compositions were stored at 0°C and 25°C for one week, and it was confirmed by appearance and touch whether the original cream form was maintained. A: The cream form was maintained; B: Partially liquefied; C: Separation occurred, or liquefaction or solidification occurred.

[0093] [High temperature stability] The cleansing compositions were placed in transparent glass containers and kept at 50°C and 60°C for 3 hours, and the appearance was observed to confirm whether the original cream form was maintained. A: The cream form was maintained; B: Partially liquefied; C: Separation occurred, or liquefaction or solidification occurred.

[0094] [Temperature change stability] The sample used in the high-temperature stability test was left to stand at room temperature for 3 hours, and its appearance was checked to see if it maintained its creamy form.The composition was also spread thinly on a blackboard to check for the presence of solid matter. A: The creamy form was maintained and no solid matter was present; B: No solids were present, but some liquefaction occurred; C: The composition was liquefied or solid matter was present.

[0095] [Foaming speed] Four expert panelists whipped each composition into lather and evaluated the speed of lathering on a 5-point scale from 5 points (excellent) to 1 point (poor), and the results were averaged to give the following rating: A: 3.5 points or more; B: 2.5 points or more and less than 3.5 points; C: Less than 2.5 points.

[0096] In Test Examples 2 and 4, which did not contain amphoteric surfactant and salt, the creams became liquid and could not be made into a creamy consistency, at least when left standing in a high-temperature environment and when returned to room temperature from a high-temperature environment. Test Example 3, which contained an amphoteric surfactant but a low salt content, became hard and solidified.

[0097] On the other hand, the composition of Test Example 1, which contained an amphoteric surfactant and 0.2% by mass or more of salt, was able to maintain its creamy form at all temperatures. It was also able to maintain its creamy form even when the temperature changed. In particular, a stable composition was obtained even when the total amount of palmitic acid and stearic acid was 10% by mass or less. Therefore, it is considered preferable to add 0.2% by mass or more of salt in addition to the addition of an amphoteric surfactant in order to obtain a creamy form that is stable at high temperatures.

[0098] In Test Examples 5 and 6, in which a cationic polymer was added, the foam quality was improved and the feeling during use was improved.

[0099] In Test Example 7, in which the proportion of stearic acid in the higher fatty acids was increased, the temperature change stability decreased. From this, it is considered preferable that the mass proportion of stearic acid in the higher fatty acids is 12 mass % or less.

[0100] In Test Examples 8 and 9, in which the type of salt was changed, both inorganic and organic salts were able to improve stability and usability.
