Description

  The present invention relates to a paste-like cleaning composition suitable for a facial cleansing foam and the like, and a method for producing the same.

  Conventionally, alkyl sulfates, alkyl ether sulfates, higher fatty acid salts and the like have been used in compositions for body cleaners such as skin and hair. However, due to the problem of irritation to the human body, instead of these, N-acyl amino acid salt-based surfactants that have little skin irritation and have excellent detergency have come to be used.

  N-acyl amino acid salt-based surfactants are excellent in terms of skin irritation, but are useful for cleaning against sebum dirt, foaming power when washing skin or hair, feeling of slimness, squeezed skin and hair. Improvement was necessary in terms of feeling. Many proposals have been made for the purpose of these improvements. For example, Patent Literature 1, Patent Literature 2, Patent Literature 3, Patent Literature 4, Patent Literature 5, and Patent Literature 6 are used in combination with various surfactants, and Patent Literature 7, Patent Literature 8, Patent Literature 9, Patent Literature 6. Document 10 proposes the use of a specific N-acyl amino acid surfactant. Furthermore, Patent Document 11 is known as a technique for improving the foam performance, the detergency against sebum dirt and hair dirt, the refreshing feeling, the feeling of feeling of tension, the creaking of the hair after use, and the irritation, especially for the human body. Yes. Moreover, the Example of patent document 12 has disclosed the example which controlled pH using the N-acyl amino acid salt type surfactant, and prepared the cleansing foam.

  However, N-acyl amino acid salt surfactants have high applicability to liquid preparations, but there is a problem that it is difficult to prepare paste preparations such as face-washing foams. That is, conventionally, when trying to obtain a paste-like composition from an N-acyl amino acid salt, a method of cooling an aqueous solution in which the N-acyl amino acid salt is supersaturated at a high temperature has been exclusively used. There is a problem that the N-acylamino acid salt is decomposed and the quality is lowered, and the solution has been desired.

  If an N-acyl glycine salt is used as the N-acyl amino acid salt, there is a possibility that a paste-like composition can be produced relatively easily by adjusting the pH. However, as disclosed in Patent Document 11, in that case, Requires the pH of the composition to be adjusted to an alkalinity of around 8, and is one of the greatest advantages of N-acylamino acid salt surfactants, which is that the low skin irritation must be sacrificed. was there.

  EXAMPLES Next, although an Example demonstrates this invention still in detail, the technical scope of this invention and its embodiment are not limited to this. The properties of the detergent compositions obtained in the examples were evaluated by the following methods.

<Evaluation of foam performance>
[Measurement method of pH]
A 10% by mass aqueous solution of the sample was prepared, and the pH was measured using a pH meter (Toa DKK Co., Ltd. HM-30G).
[Temperature measurement method]
Regarding the temperature in Step II, the temperature of the aqueous solution containing the component (A) was measured with an alcohol thermometer.

[Properties]
Using a rheometer CR-500DX-S manufactured by Sun Science Co., Ltd. 25 (dimension 20 mm), and the property which the load which measured the indentation speed on the conditions of 100 mm / min exists in the range of 1-2000 g was made into the paste form.
[Foaming power]
3.3 g of the cleaning composition was taken to 300 g with purified water, placed in a mixer, stirred for 30 seconds, the height of the foam immediately after was measured, and the “foaming power” was evaluated according to the following criteria.
○: Foam height of 18 cm or more Δ: Foam height of 16 cm or more and less than 18 cm x: Foam height of less than 16 cm

[Foam retention]
After stirring for measurement of foaming power, let stand for 5 minutes, measure the height of the foam again, find the retention rate for the height of the foam immediately after, and evaluate the "foam retention" according to the following criteria did.
Foam retention [%] = foam height after standing [cm] / foam height immediately after [cm] × 100
○: Retention rate of bubbles is 90% or more Δ: Retention rate of bubbles is 70% or more and less than 90% ×: Retention rate of bubbles is less than 70%

[Creamyness of foam]
In the measurement of foaming power, the fineness of the foam immediately after stirring was evaluated for creamy property on the basis of the following criteria for 10 male and female panelists, and the average score was defined as “foam creamy property”.
2 points: creamy (bubbles are very fine)
1 point: creamy but slightly foamed 0 point: foamed very rough Note that the temperature of the cleaning composition at the time of the above measurement was 25 ° C.

[Example 1] to [Example 5], [Comparative Example 1], [Comparative Example 2]
An aqueous solution (pH = 7.0) having the composition shown in Table 1 was adjusted to the pH shown in Table 1 at 25 ° C. using citric acid to prepare a cleaning composition. The physical properties of the obtained cleaning composition were measured by the method described above. The results are shown in the evaluation column of Table 1.

  The present invention can provide a technique for easily producing a paste-like cleaning composition such as a facial cleansing foam.
