And starting a custom 3 washing mode for cleaning, wherein the cleaning mode comprises four steps of pre-washing, boiling and washing, rinsing and drying, the boiling and washing temperature is 50 ℃, the drying temperature is 70 ℃, the washing program is 100min, the total washing water is 7.6L, and the boiling and washing water is 2.6L. After the washing procedure was completed, the dishes were numbered and scored blindly by an experienced scoring 10-person panel, and photographed for future use. The average score after the dish wash was calculated.
Testing parameters: boiling and washing temperature is 50 ℃, and drying temperature is high; 70 ℃, wash water hardness: 400PPM (calcium ion: magnesium ion = 3:1), amount of prewash water: 2.4L, the amount of boiling water is 2.6L, and the amount of rinsing water is: 2.6L, program time: for 100min. Washing procedure: DIY3.
The scoring standard is as follows: the scoring method for the different dish washing effects is shown in table 1. The score is 1-10.
TABLE 1 tableware cleaning effect scoring method
Example 1 surface tension of amino acid surfactant
Surfactants used in dishwashing detergents are mainly alkyl alcohol alkoxylate nonionic low-foaming surfactants containing EO and PO, and it is generally considered that amino acid surfactants do not satisfy the low-foaming requirement and cannot substitute alkyl alcohol alkoxylate nonionic low-foaming surfactants.
Surfactants of different amino acid varieties may have different properties. Because the detergent for the automatic dish-washing machine is mostly alkaline, the pH value of 1% solution is 9-12, the dosage of the surfactant is usually 1-3%, the surface properties of different surfactants can be known by testing the surface tension of 1% surfactant aqueous solution in mass fraction under an alkaline condition, and the detergent is helpful for screening out varieties which are suitable for the automatic dish-washing machine and have higher surface activity and stronger cleaning effect. Common amino acid surfactant solutions, including sodium lauroyl sarcosinate, potassium cocoyl glycinate, sodium cocoyl alanine, disodium lauroyl glutamate, disodium cocoyl glutamate, disodium oleoyl glutamate, sodium cocoyl methyl taurate, etc., have surface tension test results at 1% by mass, pH =10.5, 20 ℃, as shown in fig. 1.
From the results, it is found that the surface tension of glutamic acid surfactants is lower than that of other amino acid surfactants, and disodium lauroyl glutamate is the lowest, and disodium fatty acyl glutamate having a fatty acyl carbon chain length of C12 to C18 is lower than or equivalent to that of commercially available nonionic low foaming surfactants. In addition, sodium cocoyl glycinate was also lower.
Example 2 foam Properties of amino acid surfactants
Most amino acid surfactants with good surface tension properties cannot be used in machine detergents due to their foaming properties. The foam amount of the amino acid surfactant solution was measured at 55 deg.C, pH9-11, and 400PPM hard water, and the results are shown in FIG. 2.
From the results, it was found that the foams of several amino acid surfactants such as disodium lauroyl glutamate, disodium cocoyl glutamate, disodium oleoyl glutamate, and sodium cocoyl glycinate were low under the pH =9 to 11, and the foams of sodium cocoyl methyl taurate, sodium cocoyl alaninate, and sodium lauroyl sarcosinate were high under the alkaline condition. The foam of sodium lauroyl glutamate in the glutamic acid amino acid surfactant is slightly higher than that of sodium lauroyl glutamate and sodium cocoyl glutamate, and the foam of sodium lauroyl glutamate is the lowest. As previously mentioned, three glutamic surfactants, as well as cocoyl glycine surfactants, are more suitable for use in automatic dishwasher detergent products than other classes of amino acid surfactants in terms of foam performance.
Fatty acyl sodium glutamate has a structure of two sodium ions under an alkaline condition, so that the charge density is higher, more hydrogen bonds can be formed, the fatty acyl sodium glutamate has higher affinity with water, the fatty acyl sodium glutamate is more difficult to migrate to an interface and form foam, and the fatty acyl sodium glutamate is relatively loose in arrangement on the interface due to the high charge repulsion between water groups, so that the foam is less, or the foam can be broken rapidly. The charge repulsion of the hydrophilic head is slightly interfered by the influence of the carbon chain length of the fatty acyl group carried by the oleoyl, the cocoyl, the disodium lauroyl glutamate and the like, the foam characteristics are slightly different, the interference is larger when the carbon chain is longer, so that more foams are generated, and the foam amount of the disodium fatty acyl glutamate with the fatty acyl carbon chain length of C12-C18 is lower on the whole. And the fatty acyl sodium alanine, the fatty acyl sodium sarcosinate and the fatty acyl sodium methyl taurate can well reduce the interfacial tension of water and air in addition to well reducing the interfacial tension of oil and water under the alkaline condition, so that the foam under the alkaline condition can still be abundant.
EXAMPLE 3 oil removal Capacity of amino acid surfactant
The oil removal rate of the amino acid surfactant under the alkaline condition of pH =9-11 is measured, and the screening of the surfactant raw material with better cleaning power is facilitated. The amino acid surfactant solutions were tested for oil removal at pH9-11, 50 deg.C, 250PPM hard water, and the results are shown in FIG. 3.
The results show that sodium cocoyl methyl taurate and sodium cocoyl alaninate have high oil removal rates at pH =9 to 11, but are not suitable for use in detergents for automatic dish washers because of excessive foaming. The oil removal rate of sodium lauroyl sarcosinate, disodium lauroyl glutamate, disodium cocoyl glutamate and disodium oleoyl glutamate is intermediate, and can be close to that of commercially available nonionic low-foaming surfactants (alkanol EO and PO alkoxylates) commonly used for dish washing powder and dish washing blocks, and the sodium lauroyl sarcosinate is not suitable for detergents for automatic dish washing machines due to abundant foams. The oil removal rate was relatively low for sodium cocoyl glycinate which had relatively little foam.
By integrating the characteristics of foam characteristics, oil removal rate and the like, disodium fatty acyl glutamate with the fatty acyl carbon chain length of C12-C18 is selected as a surfactant, and the representative varieties of disodium lauroyl glutamate, disodium cocoyl glutamate and disodium oleoyl glutamate are used in a machine detergent to replace a commercially available nonionic low-foaming surfactant, and the disodium lauroyl glutamate is optimally selected.
Example 4
The dish washing powder for the dish washing machine is prepared by uniformly mixing and stirring the following components in parts by mass:
3 parts of disodium lauroyl glutamate
30 portions of anhydrous sodium carbonate
2.6 parts of trisodium dicarboxymethylalaninate
3 parts of sodium polyacrylate
25 portions of sodium citrate
6 portions of sodium percarbonate
30 portions of anhydrous sodium sulfate
0.2 portion of protease
0.2 part of amylase.
Performance test
As a control, a surfactant-free control was prepared: 30 parts of anhydrous sodium carbonate, 33 parts of anhydrous sodium sulfate, 25 parts of sodium citrate dihydrate, 2.6 parts of dicarboxymethylalanine trisodium, 6 parts of sodium percarbonate, 3 parts of sodium polyacrylate, 0.2 part of protease and 0.2 part of amylase are mixed and stirred uniformly to prepare the powdery uniform solid dish-washing agent.
Further, a dish detergent containing a nonionic low-foaming surfactant was prepared by replacing disodium lauroyl glutamate with a commercially available nonionic low-foaming surfactant (alkanol EO, PO alkoxylate) in an equal amount to the above dish detergent formulation.
1. Foam test
Solid powder of 3% by mass of disodium lauroyl glutamate (commercially available, new materials of south Jing Huashi, inc., eversoft TM ULS-100S) was applied to a dishwashing powder formulation, and the lather levels of the formulation samples were tested against an equivalent amount of a commercially available nonionic low-lathering surfactant (alkanol EO, PO alkoxylate) and compared to a commercially available dishwashing powder, surfactant-free blank control, and the results are shown in fig. 4. (the homemade disodium lauroyl glutamate dishwashing powder is named as 'ammonia table homemade A', the homemade nonionic surfactant 1 dishwashing powder is named as 'nonionic homemade B', the homemade nonionic surfactant 2 dishwashing powder is named as 'nonionic homemade C', the surfactant-free contrast is named as 'blank contrast', the commercially available international brand dishwashing powder is named as 'commercially available A', the commercially available Japanese brand dishwashing powder is named as 'commercially available B', and the commercially available domestic brand dishwashing powder is named as 'commercially available C')
As can be seen from fig. 4, the blank control is free of surfactant, so that no foam exists, the foam of the disodium lauroyl glutamate and the foam of two commercially available nonionic surfactants added into the dishwashing powder are lower, and the difference of the foam of the disodium lauroyl glutamate added into the dishwashing powder is not great compared with the three commercially available dishwashing powders, although the initial foam of the dishwashing powder containing the disodium lauroyl glutamate is slightly higher than that of the other dishwashing powders, the foam can be broken quickly, and the dishwasher circulating water pump is not adversely affected. It follows that disodium lauroyl glutamate can be used in detergents for automatic dishwashing machines.
2. Oil removal test
A3% mass fraction disodium lauroyl glutamate solid powder (Eversoft TM ULS-100S) was applied to a dishwashing powder formulation, and the oil removal rate of the formulation samples was tested in comparison to an equivalent amount of commercially available non-ionic low foaming surfactant (alkanol EO, PO alkoxylate) and compared to commercially available dishwashing powders and blank controls, with the results shown in FIG. 5.
As can be seen from figure 5, the oil removal rate of the home-made dishwashing powder added with 3% of disodium lauroyl glutamate is higher than that of the home-made dishwashing powder and blank reference products of nonionic surfactants with the same formula and also higher than that of three commercially available dishwashing powders, which indicates that the amino acid surfactant has certain decontamination advantage.
3. Machine washing effect test
The solid powder of disodium lauroyl glutamate with the mass fraction of 3% is applied to a dish washing powder formula, two types of commercially available nonionic low-foaming surfactants (alkanol EO and PO alkoxylates) with the same dosage are compared, the actual washing effect of a formula sample in an automatic dish washing machine is tested, the actually washed effect is compared with three types of commercially available dish washing powders and a blank reference product, a 10-person scoring group is asked to carry out blind scoring, and the comprehensive scoring result is shown in figure 6.
From the comprehensive evaluation of the group in fig. 6, the cleaning effect of the three self-made dishwashing powders is higher than that of the commercially available three dishwashing powders and far higher than that of a blank reference product, and the dishwashing powder using the lauroyl glutamic acid disodium in the three self-made dishwashing powders is slightly better than the dishwashing powders using the nonionic surfactants in the other two self-made dishwashing powders.
Example 5
The dish washing powder for the dish washing machine is prepared by uniformly mixing and stirring the following components in parts by mass:
1 part of disodium lauroyl glutamate
40 portions of anhydrous sodium carbonate
5 parts of trisodium dicarboxymethylalanine
3 parts of sodium polyacrylate
24 portions of sodium citrate
6 portions of sodium percarbonate
20 portions of anhydrous sodium sulfate
0.5 part of protease
0.5 part of amylase.
Example 6
The dish washing powder for the dish washing machine is prepared by uniformly mixing and stirring the following components in parts by mass:
5 parts of disodium lauroyl glutamate
20 portions of anhydrous sodium carbonate
2.6 parts of trisodium dicarboxymethylalanine
10 portions of sodium polyacrylate
25 portions of sodium citrate
10 portions of sodium percarbonate
32 parts of anhydrous sodium sulfate
0.2 portion of protease
0.2 part of amylase.
Example 7
A dish washing liquid for a dish washing machine comprises the following components in parts by mass:
3 parts of disodium lauroyl glutamate
20 portions of anhydrous sodium carbonate
10 parts of dicarboxymethylalanine trisodium
5 parts of sodium polyacrylate
15 portions of sodium citrate
10 portions of sodium percarbonate
0.5 part of protease
0.5 portion of amylase
And water is added to 100 parts.
The performance tests carried out on the dishwasher detergents of examples 5 to 7 gave the following results:
1. foam test
The procedure is as in example 4. The foams of the detergents of the examples 5 to 7 are similar to those of two self-made products added with nonionic surfactants and three commercially available dish washing powders, the foam quantity is low, and the foam breaking is rapid. The photograph of the foam test is shown in FIG. 7.
2. Machine washing effect
The actual washing of the formulation samples in an automatic dishwasher and compared with three commercially available dishwashing powders and a blank control, the actual washing results are shown in figures 8-11.
From the figures 8-11, it can be seen that the dish washing powder (liquid) using disodium lauroyl glutamate has very excellent performance for reducing residue of stains in transparent glass cups or removing oil stains in plastic tableware and removing rice stains and egg stains, and is better than three commercially available dish washing powders and blank reference products compared with two self-made dish washing powders made of nonionic surfactants.
The dish washing powder prepared by using the disodium lauroyl glutamate as the surfactant component of the detergent for the dish washing machine is compared with the dish washing powder which is commercially available and is prepared by using the EO and PO alkanol alkoxylated nonionic surfactant to perform a test experiment, so that the detergency of the dish washing powder is superior to that of the dish washing powder which is commercially available and contains the EO and PO nonionic surfactants, and is superior to that of the three types of dish washing powder. The disodium lauroyl glutamate is shown to be used in a dishwasher to completely replace the nonionic surfactant containing EO and PO.
