Various properties of the pearly luster composition obtained in each example and each comparative example were measured by the following methods.

<Number average major axis of pearl luster particles>
The cleaning composition is diluted 1000 times (weight ratio) with water, and the diluted solution is dropped on a slide glass and allowed to dry naturally, and is observed with a color laser microscope (VK-8500 manufactured by Keyence Corporation), and is confirmed as a crystal. The average value obtained by randomly measuring the major axis of the pearly luster particles at 100 points is defined as the number average major axis of the crystals.

<Pearl luster of cleaning composition>
The detergent composition is diluted 20 times (weight ratio) with water, the appearance of pearly luster is observed with the naked eye, and evaluated according to the following criteria. In addition, the thing in which air bubbles are mixed is centrifuged and defoamed.

〔Evaluation criteria〕
1: No gloss or weak and thin gloss is recognized.
2: Weak or thin gloss is recognized.
3: A strong dark gloss is recognized.

<Dispersion stability of pearl luster particles>
The pearly luster composition is diluted 50 times in an aqueous solution adjusted to a specific specific gravity using salt and water, and left at 20 ° C. for 18 hours, and evaluated according to the following criteria. The measurement was performed at 20 ° C.
〔Evaluation criteria〕
1: 1.035 to 1.042 stably dispersed.
2: Dispersed stably at 1.021 to 1.049.
3: Disperse stably at 1.014 to 1.056.

<Viscosity of pearly luster composition>
The pearly luster composition is held at 30 ° C. and measured. For the viscosity, a B-type viscometer (manufactured by Tokyo Keiki Co., Ltd.) was used. M4-23 was used, and the measurement was performed under the conditions of a maximum rotation speed allowed by the apparatus among a measurement temperature of 30 ° C., a measurement time of 60 seconds, and a rotation speed of 20 to 100 rpm.

<Slidability of cleaning composition>
A hair detergent composition having the composition shown in Table 1 was produced by a conventional method, and the pH was adjusted to 6.0 (20 ° C.) with sodium hydroxide. The slipperiness at the time of hair drying when using these was evaluated.

The detailed procedure of sensory evaluation is shown.
Paneler: Japanese woman.
Hot water used: Tap water of 38 to 40 ° C. (hardness 3 to 5 ° DH).
Procedure After warm water is applied to the hair and sufficiently moisturized, the hair cleaning composition of the present invention is taken in an appropriate amount (the same amount as the shampoo that the paneler uses according to the length of his hair), and the hair cleaning agent Shampoo by moving your hand so that the composition is well spread over your hair. The state after washing and drying was evaluated according to the evaluation criteria shown in Table 1 below and averaged.
1: The hair surface hardly slips.
2: The hair surface slips slightly.
3: The hair surface slides well.

<Melting point of fatty acid glycol ester or aliphatic compound>
Using a differential scanning calorimeter (Thermo plus DSC8230, manufactured by Rigaku), the fatty acid glycol ester or the aliphatic compound is heated at 5 ° C./min, and the resulting melting peak top is defined as the melting point.

Examples 1-7 and Comparative Examples 1-3
Fatty acid glycol ester which was prepared by mixing a mixture of fatty acid monoalkylolamide, alkyl sulfate ester salt, polyoxyalkylene type nonionic surfactant and other components shown in Table 2 at 80 ° C., and then melting and mixing them in advance. And the fatty acid are added in a molten state and mixed. Then, it cooled to 20 degreeC with the cooling rate of 0.5 degreeC / min, and obtained the pearl luster composition. Using this pearly luster composition, a hair cleaning composition having the composition shown in Table 1 was produced by a conventional method, and the pH was adjusted to 6.0 (20 ° C.) with sodium hydroxide.
The results are also shown in Table 2. The numerical values in the table are weight percent pure.

From the above results, it can be seen that the detergent compositions containing the pearly luster compositions of Examples 2 to 5 and 7 are excellent in pearly luster, dispersion stability and slipperiness. Examples 1 and 6 have a slightly larger particle size and slightly inferior slipperiness.
On the other hand, it can be seen that the cleaning composition containing the pearly luster composition of Comparative Example 1 having a large particle size has large pearly luster particles and low dispersion stability and slipperiness.
Moreover, the detergent composition containing the pearly luster composition of Comparative Example 2 in which no polyoxyalkylene type nonionic surfactant is blended has a remarkably high viscosity (98,000 mPa · s) as a pearly luster composition, and the blendability The pearl gloss and dispersion stability are inferior to those of the cleaning compositions of the examples. On the other hand, the viscosity of Example 2 having the same composition except for the polyoxyalkylene type nonionic surfactant is (17,000 mPa · s), and is excellent in blendability, pearly luster and dispersion stability.
It can be seen that the detergent composition containing the pearly luster composition of Comparative Example 3 has small pearly luster particles and low glossiness and slipperiness.

Examples 8 to 17 and Comparative Examples 4 to 6
A mixture of fatty acid monoalkylolamide, alkyl sulfate ester salt, polyoxyalkylene type nonionic surfactant and other components shown in Table 3 was mixed at 80 ° C., and both were previously melted and mixed. Table 3 The fatty acid glycol ester and the fatty alcohol, fatty acid monoglyceride, or aliphatic ether shown in FIG. Then, it cooled to 20 degreeC with the cooling rate of 0.5 degreeC / min, and obtained the pearl luster composition. Using this pearly luster composition, a hair cleaning composition having the composition shown in Table 1 was produced by a conventional method, and the pH was adjusted to 6.0 (20 ° C.) with sodium hydroxide.

  From the above results, it can be seen that the detergent compositions containing the pearly luster compositions of Examples 8 to 10 and 13 to 16 are excellent in pearly luster, dispersion stability and slipperiness. Examples 11 and 12 have a slightly larger particle size and slightly inferior slipperiness. In Example 17, the particle size is slightly small and the pearl luster is slightly inferior, but the slipperiness and dispersion stability are excellent. It can be seen that Comparative Examples 4 and 5 have a small particle size and inferior pearl luster, and Comparative Example 6 has a large particle size and inferior pearl luster.
