Description

  The present invention relates to a solid detergent composition.

In solid detergents molded by molding techniques such as extrusion, compression, rolling, and pouring, soaps based on higher fatty acid salts have been most commonly used as face wash or body wash.
Due to the problem of irritation to the human body, N-acylamino acid surfactants that have excellent detergency with little irritation to the skin and damage to the hair have attracted attention. A solid detergent composition comprising a higher fatty acid salt as a main component and an N-acylamino acid surfactant added thereto has been used.
However, N-acylamino acid surfactants are excellent in terms of irritation to skin and hair, but need to be improved in terms of foaming power when washing skin and hair. Moreover, there existed a problem of the melt-disintegration as a subject intrinsic | native to a solid cleaning composition, a deformation | transformation with time, etc. Many proposals have been made for the purpose of these improvements.

In addition, the solid detergent composition of the present embodiment is excellent in meltability and usability (excellent in hand washing) and has rich foaming.

  Hereinafter, the present embodiment will be described more specifically with reference to examples and comparative examples, but the present embodiment is not limited to only these examples. Note that various physical properties of the cleaning composition used in the present embodiment were measured by the following methods.

  The following ingredients were used as the ingredients listed in Table 1.

<Measurement of foaming power>
1 g of the solid detergent composition as a solute was taken up to 300 g with purified water, placed in a mixer and stirred with a mixer for 30 seconds, and the foam height (mm) immediately after that was defined as the foaming power. The measurement temperature was 25 ° C. The obtained results were judged according to the following criteria.
◎: Foaming force is 180 mm or more ○: Foaming force is 170 mm or more and less than 180 mm Δ: Foaming force is 160 mm or more and less than 170 mm x: Foaming force is less than 160 mm

<Measurement of hardness>
Measurement was performed with a rheometer manufactured by Sun Science Co., Ltd. (using CR-200D adapter No. 4), and judged according to the following criteria.
×: 12000kg / cm ² or more ○: 9000kg / cm ² more than 1200kg / cm less than ² ◎: ^4000kg / cm ² more than 9000kg / cm less than ² ○: 2000kg / cm ² more than 4000kg / cm ² less than ×: 2000kg / cm ² or less

<Comprehensive evaluation>
In the above test results, if there was no x, it was marked ◎, and if there was one x, it was marked x.

[Example 1]
A solid detergent composition was prepared by mixing using a roll at the formulation components and proportions (parts by mass) shown in Table 1, extruding, and then stamping.
The obtained solid detergent composition was evaluated and the results are shown in Table 1.

[Examples 2 to 10]
A solid detergent composition was prepared in the same manner as in Example 1. The evaluation results are shown in Table 1.

  The solid detergent compositions obtained in Examples 1 to 10 showed excellent results in foaming power and hardness.

[Comparative Examples 1 to 7]
A solid detergent composition was prepared in the same manner as in Example 1 except that the blending components and ratios (mass%) shown in Table 2 were used. The evaluation results are shown in Table 2.

The solid detergent compositions obtained in Comparative Examples 1, 2, and 4 to 7 showed excellent results in foaming power but were inferior in hardness.
Moreover, although the solid detergent composition obtained in Comparative Example 3 showed excellent results in hardness, it was inferior in foaming power.

  Since the solid detergent composition of the present invention has an appropriate hardness and excellent foaming power, it can be suitably used in the field of cosmetics and cleaning applications.
