Example

[Bubble Force Test in Hard Water]

N-acyl glutamate and higher fatty acid salts tend not to foam well when the hardness of the water at the time of washing increases. Therefore, as water used for a test, the upper limit of hardness possible as normal water supply was set. It was set as hardness 300 mg / L (300 mg as calcium carbonate in 1 liter of water) which is the upper limit of calcium concentration of Japanese tap water.

Using the cleaning agent of Tables 1-4 as a sample, the foaming force was measured by the repeated stirring method in the following procedures.

1. Calcium chloride was added to ion-exchanged water, and calcium concentration was made into 300 mg / L in calcium carbonate conversion.

2. In the composition of Tables 1-4, aqueous solution is prepared with the water prepared in 1., and it warms to 40 degreeC.

3. Pour 200 mL of warmed aqueous solution into a graduated 1 L tall beaker without foaming.

4. Set a 1 L tall beaker in an inverted stirrer (manufactured by PROMIX PR-1200 Shibata Scientific Machinery Co., Ltd.) and stir to create a bubble (right turn 20 seconds + left turn 20 seconds + right turn 20 seconds).

5. One minute after foaming, read the amount of foam (data = average value of N = 3).

The results are shown in Tables 1 to 4 and FIGS. 1 to 4.

Significant differences in the foaming amounts of Examples 1 to 3 and Comparative Examples 2 to 20 were determined based on the foaming amount of Comparative Example 1 in which N-lauroyl glutamate, N-acyl glutamate, was added alone. . In addition, based on the comparative example 1, the ratio (%) of the foaming quantity of Examples 1-3 and Comparative Examples 2-20 was calculated, the 100% was subtracted, and the foaming quantity at the time of comparison with the comparative example 1 was calculated. The increase and decrease (%) was calculated | required and shown in Tables 1-3 and FIGS.

In addition, the notation in a table | surface is shown briefly. AGS: N-lauroylglutamic acid Na, PGlu: polyγglutamic acid Na, Ser: L-serine, Gly: glycine, Pro: L-proline, Thr: L-threonine, Arg: L-arginine, Glu: L-glutamic acid .

Based on the foaming amount of the comparative example 21 which mix | blended the sodium laurate which is a high fatty acid salt alone, the significant difference of the foaming amount of Example 4, the comparative examples 22, 23 was assayed. In addition, based on the comparative example 21, the ratio (%) of the amount of foam of Example 4, the comparative examples 22, 23 was calculated, 100% was subtracted, and the increase and decrease of the amount of foam compared with the comparative example 21 ( %) Was obtained and shown in Table 4 and FIG.

In a system in which 0.5% by mass of N-acyl glutamate was blended as a surfactant, 0.001% by mass to 0.01% by mass of sodium polyglutamate was added. As a result, the foaming amount increased by 5.6% in Comparative Example 2, and Comparative Example 5 In the foam amount increased by 2.3%, in Comparative Examples 3 and 4 on the contrary, 1.0%, 4.3% foam diary decreased. As a result of blending serine with 0.001% by mass to 0.01% by mass (Comparative Examples 6-9), the foaming amount was 3.3% in Comparative Example 6, 14.5% in Comparative Example 7, 7.9% in Comparative Example 8, and 8.9% in Comparative Example 9. Increased. On the other hand, in Example 1 in which 0.005% of sodium polyglutamate and 0.005% of serine were added, the amount of foam increased by 35.3%, and in Example 2, which contained 0.001% of sodium polyglutamate and 0.001% of serine, the amount of foam increased by 34.3%. In the comparative example containing only sodium polyglutamate, 5.6% of Comparative Example 2 having the highest foaming amount and the 14.5% of Comparative Example 7 having the highest foaming amount in the comparative example containing only serine were added up to only 20.1%. Increasing the bubble power of 1 and 2 is an unexpected unexpected effect.

In the system containing 0.5% by mass of N-acyl glutamate, the difference in the enhancement effect of the foaming force according to the type of amino acid was investigated. The results are shown in Table 2 and FIG. In Comparative Examples 6 to 14 each containing 0.01% by mass of serine, glycine, proline, threonine, arginine, and glutamic acid, no significant increase in the amount of foam was observed as compared with Comparative Example 1 containing only N-acyl glutamate. . For Examples 1 and 3 to 5 each containing 0.005 mass% of neutral amino acids serine, glycine, proline and threonine together with 0.005 mass% of sodium polyglutamate, the amount of foaming was 35.3%, 14.5%, and 11.2 as compared with Comparative Example 1. % Increased by 21.1%. The increase in the foaming power of Examples 1 and 5 in combination with an aliphatic amino acid, serine and threonine, which are oxyamino acids, was particularly remarkable, and the foaming amount was increased by 1% in Example 1 and 5% in Example 5. For Example 4 in which sodium polyglutamate and glycine are combined, and Example 5 in which sodium polyglutamate and proline are combined, Comparative Examples 6 and 10 to 14 in combination with amino acids alone, and arginine as a basic amino acid together with sodium polyglutamate Compared with the comparative example 15 which mix | blended and the polyglutamic acid sodium, and the comparative example 16 which mix | blended glutamic acid which is an acidic amino acid, the amount of foams increased significantly.

In the system which mix | blended N-acyl glutamate 0.5 mass%, the effect of sodium polyaspartate was investigated instead of sodium polyglutamate. The results are shown in Table 3 and FIG. 3. In Comparative Example 17 in which 0.01% by mass of polyaspartic acid sodium was added alone and Comparative Example 6 in which 0.01% by mass of serine alone were added, the increase in the amount of foam was not found to be 4.6% and 3.3%. In Example 6 in which 0.005 mass% of sodium polyaspartate and 0.005 mass% of serine were blended, the amount of foam increased by 38.6%. The increase in the amount of bubbles compared to Comparative Example 1 of Example 6 is 1% significant. Even if the increase of the amount of foam of Comparative Example 17 and Comparative Example 6 was summed up, it is only 7.9%, and the increase of the amount of foam of Example 6 is an unexpected unexpected effect.

Instead of N-acyl glutamate, the experiment was conducted in a system in which 0.5 mass% of sodium laurate, a higher fatty acid salt, was blended. The results are shown in Table 4 and FIG. 4. Similarly to the system of N-acyl glutamate, the synergistic effect by combining polyglutamate and neutral amino acid was confirmed.

[Bubble Force Test in Ion Exchange Water]

By blending polyamino acid and neutral amino acid in N-acyl glutamate or higher fatty acid salt, foaming in hard water is remarkably improved. In order to investigate whether the same effect also arises in ion-exchange water, the foaming force was measured by the repeated stirring method in the following procedure using the cleaning agent of Tables 5 and 6 as a sample.

1. In the compositions of Tables 5 and 6, an aqueous solution is prepared with ion-exchanged water and warmed to 40 ° C.

2. Pour 200 mL of the warmed aqueous solution into a graduated 1 L tall beaker to prevent foaming.

3. Set a 1 L tall beaker in an inverted stirring device (manufactured by PROMIX PR-1200 Shibata Scientific Machinery Co., Ltd.) and stir to create a bubble (right turn 20 seconds + left turn 20 seconds + right turn 20 seconds).

4. One minute after foaming, read the amount of foam (data = average value of N = 3).

The results are shown in Tables 5 and 6 and FIGS. 5 and 6.

Based on the foaming amount of the comparative example 21 which combined N-lauroyl glutamate which is N-acyl glutamate only, the significant difference of the foaming amount of Example 8 and Comparative Examples 22-25 was assayed. In addition, the ratio (%) of the amount of foam of Example 8 and Comparative Examples 22-25 was calculated based on the comparative example 21, the 100% was subtracted, and the increase and decrease of the amount of foam compared with the comparative example 21 ( %) Was obtained and shown in Table 5 and FIG.

Significant difference of the amount of foam of Example 9 was assayed based on the amount of foam of Comparative Example 26 in which sodium laurate which is a higher fatty acid salt was added alone. In addition, based on the comparative example 26, the ratio (%) of the bubble amount of Example 9 was calculated, 100% was subtracted, and the increase and decrease (%) of the bubble amount compared with the comparative example 26 was calculated | required, and the table 6 and FIG. 6.

In a system containing 0.5% of N-lauroyl glutamate, sodium polyglutamate and serine were each mixed alone (Comparative Examples 22 to 25), compared with Comparative Example 21 containing only N-acyl glutamate. No significant increase in the amount of foam was found. However, in Example 8 in which 0.005 mass% of sodium polyglutamate and 0.005 mass% of serine were blended, the amount of bubbles increased by 5% significantly as compared with Comparative Example 21. Also in the ion-exchanged water of hardness 0, the synergistic effect of polyglutamate and neutral amino acid was confirmed.

In the system in which 0.5% Na laurate was blended as the higher fatty acid salt, Example 9 in which 0.005% by mass of sodium polyglutamate and 0.005% by mass of serine was blended, was compared with Comparative Example 26 containing only higher fatty acid salts. 1% significantly increased the amount of foam. In the system in which the higher fatty acid salt was blended, the blending effect of the polyglutamate and the neutral amino acid was confirmed even when ion exchanged water having a hardness of 0 was used (see Table 6 and FIG. 6).

In addition, even at hardness 50, which is the hardness of Japanese standard tap water, the effect of enhancing the foaming force by adding polyglutamate or polyasparagine acid salt and neutral amino acid was confirmed.

[Bubble Hardness Test in Ion Exchange Water]

In order to investigate whether foams are hardened by mix | blending polyamino acid and neutral amino acid with N-acyl glutamate, the hardness of foam was measured in the following procedure using the cleaning agent of Table 7 as a sample.

1. In the composition of Table 7, an aqueous solution was prepared with ion-exchanged water.

2. 10 g of the warmed aqueous solution was put into a whipping machine "Whipp Creamer Slim CMS-1 Hario Glass Co., Ltd.", and foaming was carried out under the conditions of whipping speed: 2 times / second, whipping frequency: 20 round trips.

3. The hardness of the obtained foam was measured using the rheometer RT2002J made from Leotek, and the adapter measured using φ 30 mm. Longitude read the maximum value. The foaming of each sample was performed three times, the hardness was measured, and the average value was obtained. In addition, based on the comparative example 27, the ratio (%) of the hardness of Example 10 was calculated, 100% was subtracted, and the hardness increase and decrease (%) compared with the comparative example 27 was calculated | required. The results are shown in Table 7, FIG.

The hardness of the foam of Example 10 was increased by 34% compared with the hardness of the foam of Comparative Example 27, so that firm foaming could be realized.

[Observing electron microscope of bubble]

In the composition of Table 8, the face-wash powder of Comparative Example 28 and Example 11 was prepared.

Water was added to the face-wash powder, foaming was performed by hand, the bubble mass was put on the stainless plate, and air-dried for 1 day.

Airy bubbles are shown in FIG. 8. The inside of the bubble was taken out and observed with the scanning electron microscope.

The bubbles of Comparative Example 28 are shown in FIGS. 9 and 10, and the bubbles of Example 11 are shown in FIGS. 11 and 12.

The foam of Example 11 is dense and uniform, whereas the foam of Comparative Example 28 is significantly non-uniform. 10 and 12, the foam film of Fig. 12 (Example 11) is thickened. The foam film of Example 11 is firm compared with the foam film of Comparative Example 28, and it is inferred that the foam is dried without bursting.

By using the cleaning agent composition of the present invention, strength and firm foam can be realized.
