Description

  The present invention relates to a cleaning composition.

In general, an anionic surfactant is used as the surfactant of the cleaning composition. Conventionally, as a method for improving the foaming of an anionic surfactant, a combination of a plurality of surfactants (for example, a foaming skin cleansing composition containing an N-acylamino acid alkali salt and maltitol hydroxy aliphatic ether (patented) Reference 1: Japanese Patent Laid-Open No. 2000-204035)), a specific polymer is blended (for example, a foaming skin cleansing material blended with an acrylic polymer emulsion (Patent Document 2: Japanese Patent Laid-Open No. 9-125091)) Things have been done. Further, when tap water is used, foaming is impaired by calcium ions contained therein, and therefore a chelating agent is generally blended (Patent Document 3: Japanese Patent Laid-Open No. 62-121800). However, chelating agents have components that are at risk of allergies and may have safety problems.
As for polyamino acids, a surfactant composition that suppresses skin irritation caused by blending polyglutamic acid or polyaspartic acid (Patent Document 4: Japanese Patent Laid-Open No. 63-35698), and foaming by blending polyaspartic acid. A cleaning composition (Patent Document 5: Japanese Patent Laid-Open No. 7-310100) with an improved amount and foam retention is known.
However, it is not known that the foaming power of the cleaning composition is remarkably improved by blending polyglutamic acid or polyaspartic acid with a specific amino acid.

[ Foamability test in hard water ]
N-acyl glutamate and higher fatty acid salts tend to have poor foaming when the hardness of water during washing increases. Therefore, the upper limit of hardness that can be used as a normal water supply was set as the water used in the test. The hardness was 300 mg / L (300 mg of calcium carbonate in 1 liter of water), the upper limit of the calcium concentration in tap water in Japan.
Using the cleaning materials in Tables 1 to 4 as samples, the foaming force was measured by the repeated procedure according to the following procedure.
1. Calcium chloride was added to ion-exchanged water so that the calcium concentration was 300 mg / L in terms of calcium carbonate.
2. In the composition of Tables 1-4, Prepare an aqueous solution with the water prepared in step 1 and warm to 40 ° C.
3. Pour 200 mL of the warmed aqueous solution into a 1 L tall beaker with a scale so as not to foam.
4. Place a 1 L tall beaker on an inverted stirrer (PROMIX PR-1200 manufactured by Shibata Scientific Instruments Co., Ltd.) and stir to foam. (Right rotation 20 seconds + Left rotation 20 seconds + Right rotation 20 seconds)
5. After 1 minute of foaming, read the amount of foam. (Data is the average value of N = 3)
The results are shown in Tables 1 to 4 and FIGS.

Based on the foam amount of Comparative Example 1 in which N-acylglutamate sodium N-lauroyl glutamate alone was blended, a significant difference in the foam amount of Examples 1 to 3 and Comparative Examples 2 to 20 was tested. Moreover, the ratio (%) of the foam amount of Examples 1-3 and Comparative Examples 2-20 was calculated on the basis of the comparative example 1, and 100% was subtracted and the foam amount increase / decrease when compared with the comparative example 1 was calculated. (%) Was obtained and shown in Tables 1 to 3 and FIGS.
Note that the notation in the chart is simplified. AGS: N-lauroyl glutamate Na, PGlu: polyγ-glutamate Na, Ser: L-serine, Gly: glycine, Pro: L-proline, Thr: L-threonine, Arg: L-arginine, Glu: L-glutamic acid,

  Based on the amount of foam of Comparative Example 21 in which sodium laurate, which is a higher fatty acid salt, was blended alone, a significant difference in the amount of foam of Example 4 and Comparative Examples 22 and 23 was tested. Moreover, the ratio (%) of the amount of foam of Example 4 and Comparative Examples 22 and 23 was calculated on the basis of Comparative Example 21, and the increase / decrease (%) of the amount of foam when compared with Comparative Example 21 by subtracting 100%. ) Was obtained and shown in Table 4 and FIG.

  In a system in which 0.5% by mass of N-acyl glutamate as a surfactant was blended, 0.001% to 0.01% by weight of sodium polyglutamate was blended. As a result, in Comparative Example 2, the amount of foam was 5.6%. In Comparative Example 5, the amount of foam increased by 2.3%, but in Comparative Examples 3 and 4, on the contrary, 1.0% and 4.3% foaming decreased. As a result of blending 0.001 mass% to 0.01 mass% of serine (Comparative Examples 6 to 9), the amount of foam was 3.3% in Comparative Example 6, 14.5% in Comparative Example 7, and 7 in Comparative Example 8. 9% and increased by 8.9% in Comparative Example 8. On the other hand, in Example 1 containing 0.005% sodium polyglutamate and 0.005% serine, the amount of foam increased by 35.3%, and in Example 2 containing 0.001% sodium polyglutamate and 0.001% serine, The amount of foam increased by 34.3%. Even if 5.6% of Comparative Example 2 in which the amount of foam increased the most in Comparative Example containing only sodium polyglutamate and 14.5% of Comparative Example 7 in which the amount of foam increased most in Comparative Example containing only Serine Since it remains at 20.1%, the increase in foaming power of Examples 1 and 2 is a remarkable effect that cannot be predicted.

  In a system containing 0.5% by mass of N-acyl glutamate, the difference in the foaming power enhancement effect depending on the type of amino acid was examined. The results are shown in Table 2 in FIG. In Comparative Examples 6 to 14 containing 0.01% by mass of serine, glycine, proline, threonine, arginine, and glutamic acid, significant increase in the amount of foam was recognized as compared with Comparative Example 1 containing only N-acyl glutamate. I couldn't. In Examples 1 and 3-5, in which 0.005% by mass of serine, glycine, proline, and threonine, which are neutral amino acids, together with 0.005% by mass of sodium polyglutamate, the amount of foam was 35 compared to Comparative Example 1. .3%, 14.5%, 11.2%, 21.1% increase. The increase in foaming power of Examples 1 and 5 containing aliphatic amino acids and oxyamino acids serine and threonine is particularly remarkable, Example 1 is 1% significant, and Example 5 is 5% significant and foam. The amount increased. Example 4 in which sodium polyglutamate and glycine were blended, Example 5 in which sodium polyglutamate and proline were blended, Comparative Examples 6 and 10-14 in which amino acids were blended alone, and arginine which is a basic amino acid together with sodium polyglutamate The amount of foam was greatly increased as compared with Comparative Example 15 in which the acidic amino acid glutamic acid was added together with Sodium Polyglutamate in Comparative Example 15.

  In a system containing 0.5% by mass of N-acyl glutamate, the effect of sodium polyaspartate was examined in place of sodium polyglutamate. The results are shown in Table 3 in FIG. In Comparative Example 17 containing 0.01% by mass of sodium polyaspartate alone and Comparative Example 6 containing 0.01% by mass of serine alone, the increase in the amount of foam was 4.6% and 3.3%. There was no significant increase. In Example 6 in which 0.005% by mass of sodium polyaspartate and 0.005% by mass of serine were blended, the amount of foam increased by 38.6%. The increase in the amount of foam in Example 6 compared to Comparative Example 1 is 1% significant. Even if the increase of the bubble amount of Comparative Example 17 and Comparative Example 6 is added up, it remains at 7.9%, and the increase of the bubble amount of Example 6 is a remarkable effect that cannot be predicted.

  Experiments were conducted in a system in which 0.5% by mass of sodium laurate, which is a higher fatty acid salt, was blended in place of N-acyl glutamate. The results are shown in Table 4 in FIG. Similar to the N-acyl glutamate system, a synergistic effect was observed by blending polyglutamate and a neutral amino acid.

[ Foaming test with ion-exchanged water ]
By adding a polyamino acid and a neutral amino acid to N-acyl glutamate or higher fatty acid salt, foaming in hard water was remarkably improved. In order to investigate whether the same effect occurs in ion-exchanged water, the foaming force was measured by the repeated stirring method according to the following procedure using the cleaning materials in Tables 5 and 6 as samples.
1. With the compositions shown in Tables 5 and 6, an aqueous solution is prepared with ion-exchanged water and heated to 40 ° C.
2. Pour 200 mL of the heated aqueous solution into a 1 L tall beaker with a scale so as not to foam.
3. Set a 1 L tall beaker on an inverted stirrer (PROMIX PR-1200 manufactured by Shibata Kagaku Kogyo Co., Ltd.) and stir to foam. (Right rotation 20 seconds + Left rotation 20 seconds + Right rotation 20 seconds)
4). After 1 minute of foaming, read the amount of foam. (Data is average value of N = 3)
The results are shown in Tables 5 and 6 and FIGS.

Based on the foam amount of Comparative Example 21 in which sodium N-lauroyl glutamate, which is an N-acyl glutamate, was blended alone, a significant difference in the foam amount of Example 8 and Comparative Examples 22 to 25 was tested. Moreover, the ratio (%) of the bubble amount of Example 8 and Comparative Examples 22-25 was calculated on the basis of the comparative example 21, and 100% was subtracted, and the increase / decrease (%) of the bubble amount when compared with the comparative example 21 ) Was obtained and shown in Table 5 and FIG.
Based on the amount of foam of Comparative Example 26 in which sodium laurate, which is a higher fatty acid salt, was blended alone, a significant difference in the amount of foam of Example 9 was tested. Further, the ratio (%) of the amount of foam of Example 9 was calculated with reference to Comparative Example 26, and 100% was subtracted to obtain the increase / decrease (%) of the amount of foam when compared with Comparative Example 26. Table 6 This is shown in FIG.

  In a system containing 0.5% N-lauroyl glutamate, even if sodium polyglutamate and serine were added individually (Comparative Examples 22 to 25), compared with Comparative Example 21 containing only N-acyl glutamate. There was no significant increase in foam volume. However, in Example 8 in which 0.005% by mass of sodium polyglutamate and 0.005% by mass of serine were blended, the amount of foam was significantly increased by 5% compared to Comparative Example 21. A synergistic effect of polyglutamate and neutral amino acid was also observed in ion-exchanged water having a hardness of 0.

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

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

[Foam hardness test with ion-exchanged water]
In order to examine whether or not the foam is hardened by blending a polyamino acid and a neutral amino acid with N-acyl glutamate, the hardness of the foam was measured by the following procedure using the cleaning material of Table 7 as a sample.
1. An aqueous solution was prepared with ion-exchanged water having the composition shown in Table 7.
2. 10 g of the heated aqueous solution was weighed in a whip device “Whipped Creamer Slim CMS-1 manufactured by Hario Glass Co., Ltd.” and foamed under the conditions of whipping speed: 2 times / second and whipping frequency: 20 reciprocations.
3. The hardness of the obtained foam was measured using a rheometer RT2002J manufactured by Rheotech, and the adapter using φ30 mm. The hardness was read as the maximum value. Each sample was bubbled three times, the hardness was measured, and the values were averaged. Further, based on Comparative Example 27, the hardness ratio (%) of Example 10 was calculated, and 100% was subtracted to determine the increase / decrease (%) in hardness when compared with Comparative Example 27. The results are shown in Table 7 and FIG.

  The foam hardness of Example 10 was increased by 34% compared to the hardness of the foam of Comparative Example 27, and solid foaming could be realized.

[Electron microscopic observation of bubbles]
With the composition shown in Table 8, face wash powders of Comparative Example 28 and Example 11 were prepared.
Water was added to the face-washing powder and foamed by hand. The lump of foam was placed on a stainless steel plate and air-dried for one day.
The air-dried foam is shown in FIG. The inside of the foam was taken out and observed with a scanning electron microscope.
The foam of Comparative Example 28 is shown in FIGS. 9 and 10, and the foam of Example 11 is shown in FIGS.
Compared to the large and non-uniform foam of Comparative Example 28, the foam of Example 11 is fine and uniform. Moreover, when FIG. 10 and FIG. 12 are compared, the foam film of FIG. 12 (Example 11) is thick. It is inferred that the foam film of Example 11 is stronger than the foam film of Comparative Example 28, and the foam is dry without bursting.
By using the cleaning composition of the present invention, a strong and firm foam can be realized.
