The detergents prepared in examples 1 to 7 and comparative examples 1 to 7 were subjected to stability test, foam property test and viscosity test, and the specific test methods were as follows: and (3) stability testing: the detergents prepared in examples 1 to 7 and comparative examples 1 to 7 were respectively placed in an oven at 50 ℃ and a refrigerator at-5 ℃ and observed for turbidity or delamination after one week. And (3) testing the foam performance: the detergents prepared in examples 1 to 7 and comparative examples 1 to 7 and having a mass concentration of 20mL 0.1% are added into a 100mL measuring cylinder, and vibrated up and down 30 times at a speed of 2S/m, and the foam volume (mL) at that time is recorded, namely the foaming power of the detergent. Viscosity measurements were performed according to GB/T15357-1994.
The test results are shown in table 1:
table 1 list of performance test results
Figure BDA0002584931510000111
Figure BDA0002584931510000121
As can be seen from the data in Table 1, the detergents prepared in examples 1 to 7 have no turbidity after being stored in an oven at 50 ℃ for one week, and have no turbidity or delamination after being stored in a refrigerator at-5 ℃ for one week, so that the detergents prepared by the formulations in examples 1 to 7 have good high and low temperature stability. The viscosity of the examples 1 to 7 is obviously higher than that of the comparative examples 1 to 7, and the foam performance is good and is superior to that of the comparative examples 1 to 7. The data in table 1 show that example 4 performs optimally.
Example 8
Influence of NaCl addition on cloud point of cardanol polyoxyethylene ether borate BGFB20
The hydrogen bonding between the molecules of the nonionic surfactant and the water molecules is destroyed at high temperature, so that when the temperature of the surfactant solution rises to a certain value, the originally dissolved surfactant is separated out of the solution, and the system becomes turbid. While the presence of inorganic salts weakens the interaction forces between them, nonionic surfactants exhibit a lower cloud point in solutions in which inorganic salts are present. The existence of a certain amount of NaCl in the mother liquor will certainly affect the cloud point of the nonionic surfactant system.
The cloud point test is carried out according to the method A in GB/T5559-2010, cardanol polyoxyethylene ether borate BGFB20 is prepared into 100mL of 1 wt% aqueous solution, 15mL of the aqueous solution is put into a 50mL test tube, a thermometer is inserted into the test tube, the test tube is placed in a water bath at 100 ℃, the temperature is raised until the sample solution is turbid, the test tube is taken out and stirred by the thermometer until the turbidity disappears, and the reading of the thermometer is the cloud point of the sample. The process is repeated for 3 times, and an average value is taken to obtain a final CP value, the specific result is shown in figure 1, and figure 1 is a curve diagram of the addition amount of NaCl and the cloud point of cardanol polyoxyethylene ether borate BGFB 20.
CP is the upper temperature limit for the use of nonionic surfactants, and the higher CP, the greater the range of nonionic surfactant temperatures used. The results in fig. 1 show that the turbidity point of BGFB20 is up to 100 ℃ without NaCl addition, indicating that BGFB20 has better temperature resistance. The cloud point of NaCl is reduced by adding NaCl, and the cloud point is lower when the added amount of NaCl is larger, and when the added amount of NaCl reaches 13%, the cloud point of BGFB20 is reduced to 58 ℃. And the NaCl content in the AAS mother liquor is about 13 percent, which shows that the BGFB20 can stably exist in the AAS mother liquor (sodium lauroyl sarcosinate mother liquor or sodium lauroyl glutamate mother liquor).
Example 9
Surface tension of AAS mother liquor (sodium lauroyl sarcosinate mother liquor or sodium lauroyl glutamate mother liquor)
For pure liquids, the surface tension of water is the greatest among common liquids. The surface tension of water at 25 ℃ is 72.75mN/m, while the surface tension of alkanes is smaller, e.g. 21.80mN/m in n-octane at 25 ℃. The surfactant is an amphiphilic molecule, the hydrophilic group is a polar group, and the lipophilic group is a hydrocarbon chain. After the surfactant is dissolved in water, it is enriched at the surface (called surface adsorption) because the lipophilic part is desired to be dehydrated, hydrophilic groups are inserted in the water, and lipophilic groups stand on the water surface. Equal to changing the surface of water to a lipophilic tightly packed surface, which is equivalent to the surface of an alkane, the surface tension is reduced. The results of measuring the surface tension of the AAS mother liquor stock solution at 25 ℃ by the hanging piece method using a JK99C full-automatic tensiometer are shown in table 2.
Table 2 surface tension test results of AAS mother liquor
Sample (I) Sar-1 Sar-2 Gly-1 Gly-2
Surface tension (mN/m) 24.167 25.875 29.542 28.525
In Table 2, Sar-1, Sar-2, Gly-1, and Gly-2 are two different batches for producing mother liquor of sodium lauroylsarcosine and mother liquor of sodium lauroyl glutamate, respectively. As is clear from the data in the table, the surface tension of the AAS mother liquor is much lower than that of pure water (72.75mN/m), indicating that sodium lauroyl sarcosinate and sodium lauroyl glutamate remain in the AAS mother liquor.
The mother liquor of sodium lauroyl sarcosine or the mother liquor of sodium lauroyl glutamate is two varieties in AAS mother liquor, and is respectively waste liquor generated by producing sodium lauroyl sarcosine and sodium lauroyl glutamate, and the components and the content of the waste liquor are almost the same. The AAS mother liquor is the mother liquor of the amino acid surfactant and is a kind of waste water generated in the production of the amino acid surfactant.
Example 10
Preservative challenge test for formulations based on sodium lauroyl sarcosinate mother liquor
The purpose of this test is to demonstrate the advantage of the self-preservation effect of the detergent formulated with the sodium lauroyl sarcosinate mother liquor, there are two samples used in this experiment, sample 1 is made of the following components in mass percent: 7% of fatty alcohol-polyoxyethylene ether sodium sulfate AES, 4% of alkyl glycoside APG0810, 2% of cardanol polyoxyethylene ether borate BGFB20, 1% of sodium lauroyl sarcosinate, 1.2% of pH regulator sodium hydroxide, 0.2% of essence and 84.6% of sodium lauroyl sarcosinate mother liquor.
The control sample 2 is prepared from the following components in percentage by mass: 7% of fatty alcohol-polyoxyethylene ether sodium sulfate AES, 4% of alkyl glycoside APG0810, 2% of cardanol polyoxyethylene ether borate BGFB20, 1% of sodium lauroyl sarcosinate, 0.2% of essence and 85.8% of deionized water.
The preservative challenge experiment was performed as follows:
placing 9mL of sample to be tested into a container, sterilizing at high temperature and high pressure (0.15Mpa, 121.3 deg.C, sterilizing for 25min), and inoculating 1mL of bacterial suspension (the colony count is about 10) of bacteria (Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, Staphylococcus aureus) and fungi (Aspergillus niger, Candida albicans) respectively8CFU) to mix the sample and bacterial suspension uniformly. 100. mu.L of the sample was inoculated into a solid medium (bacterial medium: 1% tryptone, 0.5% yeast extract, 1% sodium chloride, 1.8% agar, 95.7% deionized water; fungal medium: 1% tryptone, 4% glucose, 1.8% agar, 93.2% deionized water) at 1 week, 2 weeks, 3 weeks, and 4 weeks of inoculation, and after several days of culture, colonies were observed and photographed, and the number of colonies was recorded for the medium with the smaller number of colonies. If the viable bacteria amount in the sample is reduced to less than 100cfu/mL within one to two weeks after inoculation and can be reduced to 0cfu/mL within four weeks, the sterilization capability of the sample to the test strain is considered to be excellent; and if the amount of viable bacteria in the sample is within one to two weeks after inoculationWhen the concentration is reduced to the range of 100-1000 cfu/mL, the sample is regarded as having the bactericidal capacity on the tested strain, but the effect is general and barely reaches the standard; if the viable bacteria amount in the sample is still more than 1000cfu/mL in two weeks after the bacteria addition, the sample is regarded as that the sterilization capability of the bacteria does not reach the standard, and the antiseptic effect is not achieved. Only when the bactericidal capacity of the sample to the tested 6 strains reaches the standard, the sample can be regarded as passing the microbial challenge experiment and has the antiseptic efficacy, and if the bactericidal capacity of the sample to one of the strains does not reach the standard, the sample is regarded as failing to pass the antiseptic challenge experiment.
FIGS. 2 and 3 are schematic representations of the results of preservative challenge experiments for samples 1 and 2, respectively, and the results in FIG. 2 show that all of E.coli (E.c), Bacillus subtilis (B.s), Pseudomonas aeruginosa (P.a), Staphylococcus aureus (S.a), and Candida albicans (C.a) inoculated into the samples were completely killed within the first week, although 8 Aspergillus niger colonies grew on the culture medium of the first week, meaning that Aspergillus niger (A.n) was present in the samples at about 80cfu/mL (< 100cfu/mL), but no colonies grew upon retesting in the second week, indicating that the number of viable Aspergillus niger in sample 1 had dropped to 0. Therefore, according to the evaluation standard of the preservation performance, the sample with the viable bacteria amount of less than 100cfu/mL after 7 days of inoculation and the viable bacteria amount reduced to zero in four weeks is regarded as having excellent preservation performance, and the sample passes the challenge and is excellent in preservation performance. Thus, the formula has good self-corrosion resistance. As can be seen from the challenge results of sample 2, fig. 3, the sample failed the preservative challenge test because none of the e.coli (e.c), pseudomonas aeruginosa (P.a) and aspergillus niger (A.n) inoculated into the sample within 4 weeks was completely killed. The formulation of sample 2 differs from the formulation of sample 1 in that: sample 1 was prepared with sodium lauroyl sarcosinate mother liquor and sample 2 was prepared with deionized water, and no pH modifier was added to sample 2, but the pH of both sample 1 and sample 2 was 7. It can be seen that the formulation prepared with the sodium lauroyl sarcosinate mother liquor, sample 1, had a particular self-preservation effect, whereas the formulation prepared with deionized water did not.
