Abstract
The invention provides a stable tableware detergent composition containing a cationic surfactant, which comprises the following components in percentage by mass: 1-4% of alpha-hexyl-omega-hydroxyl poly (oxy-1, 2-ethylene-diyl), 0.2-0.8% of cationic surfactant, 10-20% of other surfactant and 0.1-3% of auxiliary agent, wherein the cationic surfactant is hydroxyethyl lauryl dimethyl ammonium chloride. Under a certain proportion, the cationic surfactant and the anionic surfactant can form micelles with special structures, so that CMC value (critical micelle concentration) can be effectively reduced; moreover, the alpha-hexyl-omega-hydroxyl poly (oxy-1, 2-ethylene glycol) is used as a nonionic surfactant, plays a good solubilization effect in an anionic-cationic surfactant compound system, can reduce the conditions of turbidity, split phase, precipitation and the like caused by difficult combination of micelles, and the prepared detergent has good and stable deoiling effect.
Description
Technical Field
The invention relates to the technical field of detergents, in particular to a stable tableware detergent composition containing a cationic surfactant and a preparation method thereof.
Background
At present, the detergent industry has high homogeneity, and detergent products are different in size and lack of innovation, thus impeding the development of the detergent industry. As a common household product, the development of the detergent is guided by the requirements of consumers, and innovations are performed on the product. In addition, consumers have higher requirements on detergent products, and the detergent products are required to have the characteristics of high-efficiency decontamination, deoiling, mildness, convenience in use and the like. Therefore, there is a need to develop convenient ways of use, find suitable surfactants, and study detergent formulations that are efficient in degreasing.
Sodium dodecyl benzene sulfonate (LAS) is a well known surfactant commonly used in the detergent industry, and formulation systems containing LAS surfactants are relatively conventional, have better greasy dirt removing capability, are low-cost and are used in large amounts in detergent formulations. However, the dodecyl benzene carbon chain is derived from petrochemical industry, and is not environment-friendly enough compared with other surfactants, and the raw material is deep in color and luster, so that the appearance of the product is often influenced.
According to the previous researches, the anionic-cationic surfactant compound system generates a precipitate or flocculent complex due to the interaction of the anionic surfactant and the cationic surfactant in the aqueous solution, thereby generating a negative effect and even losing the surface activity of the surfactant. Therefore, how to improve the activity of the system and maintain the stability of the system is a very important topic in the detergent industry.
In view of the foregoing, research and development of a detergent with good and stable degreasing effect is needed to solve the problems in the prior art and meet the current market demands.

The invention has the following beneficial effects:
1. The stable tableware detergent composition containing cationic surfactant is one recipe without dodecyl benzene sulfonic acid and has mainly surfactant component containing natural plant-based carbon chain and compounded specific cationic surfactant. The detergent composition is a weakly acidic to neutral formulation, and the pH is controlled to be 6-7. The cationic surfactant adopted by the invention is hydroxyethyl alkyl dimethyl ammonium chloride, and can be well compatible with anionic surfactant, thereby playing a role in synergy. Under a certain proportion, the cationic surfactant and the anionic surfactant can form micelles with special structures, critical micelles are easy to form when the cationic surfactant and the anionic surfactant are compounded, CMC value (critical micelle concentration) can be effectively reduced, the smaller CMC is, the lower the concentration required for forming micelles is, the lower the concentration required for degreasing is, and the better the washing performance is. Therefore, the compound system can obviously improve the surface activity efficiency and the oil removal rate.
2. Meanwhile, we have found that, unexpectedly, the added nonionic surfactant alpha-hexyl-omega-hydroxy poly (oxy-1, 2-ethanediyl) can play a synergistic effect with an anionic-cationic surfactant compound system, and a better deoiling effect is obtained. Meanwhile, the nonionic surfactant plays a good solubilization effect in the anion-cation surfactant compound system, can reduce the strong electrostatic attraction effect of positive and negative charges of the anion-cation surfactant, and reduces the conditions of turbidity, phase separation, precipitation and the like caused by difficult combination of micelles. Therefore, the problem of incompatibility of the high-dosage anionic-cationic surfactant can be solved to a certain extent, and the system stability of the formula is improved.

Examples

s1, adding deionized water (70 wt% of the total mass) at 30 ℃ into a container according to the mass fraction, adding AES, and stirring for 20min to completely dissolve;

Comparative examples 1 to 4 were set based on example 1, and the composition ratios of the dishwashing detergents in comparative examples 1 to 4 are shown in Table 2.
TABLE 2 Components and mass fractions of the dishwashing detergent compositions of comparative examples 1-4
The comparative example differs from example 1 in that:
Comparative example 1 removal of the cationic surfactant hydroxyethyllauryldimethyl ammonium chloride; comparative example 2 the nonionic surfactant CS 6250 was removed; comparative example 3 the cationic surfactant hydroxyethyllauryldimethyl ammonium chloride was replaced with an equal mass fraction of conventional cationic surfactant 1227; comparative example 4 the nonionic surfactant CS 6250 was replaced with equal mass fractions of isomeric tridecanol ether TO8, the other ingredients and preparation method being the same as in example 1.
Test case
The dishwashing detergent compositions prepared in the examples and comparative examples were tested.
1. Product oil removal test
The testing method comprises the following steps:
Preparing hot pot oil and vegetable oil with the mass ratio of 1:1 into artificial greasy dirt, cleaning a glass sheet with the thickness of 25mm multiplied by 75mm before an experiment, and weighing after airing, wherein the weight is recorded as M 0; dripping 0.2g of artificial oil stain on the surface of the glass sheet, and uniformly spreading the artificial oil stain on the surface of the glass sheet, wherein the total weight is M 1;
Placing the glass sheet at 0 ℃ for 1h, accelerating aging, and then taking out and recovering the room temperature; 30mL of the dish detergent compositions of examples 1-4 and comparative examples 1-4 were added to 50mL of a fixed volume plastic tube, respectively, and the mixture was placed in a glass plate, allowed to stand for 5min, taken out, rinsed with 500mL of 250ppm hard water, dried in the air, weighed, and recorded as M 2.
The oil removal rate calculation formula is as follows:
oil removal= (M 1-M2)/(M1-M0) ×100%.
The results obtained are shown in Table 3.
TABLE 3 determination of the oil removal rates of the dishwashing detergent compositions of examples 1-4 and comparative examples 1-4
| Sample of | Oil removal rate (%) |
| Example 1 | 75.36 |
| Example 2 | 82.37 |
| Example 3 | 99.49 |
| Example 4 | 99.76 |
| Comparative example 1 | 39.94 |
| Comparative example 2 | 55.37 |
| Comparative example 3 | 20.68 |
| Comparative example 4 | 54.26 |
From the results shown in Table 3, the dishwashing detergent compositions of examples 1-4 have the advantages that the micelle structure of the original system is changed under a certain proportion due to the introduction of the nonionic surfactant alpha-hexyl-omega-hydroxypoly (1, 2-ethanediyl oxide) and the cationic surfactant hydroxyethyl lauryl dimethyl ammonium chloride, so that a synergistic effect is generated, and the deoiling effect is effectively enhanced; whereas comparative example 1 resulted in poor degreasing due to the absence of the cationic surfactant hydroxyethyllauryldimethyl ammonium chloride; the cationic surfactant hydroxyethyl lauryl dimethyl ammonium chloride is introduced in comparative example 2, so that the degreasing effect can be improved to a certain extent, but the effect is not ideal. Comparative example 3 the oil removal rate of a dishwashing detergent composition was reduced by changing hydroxyethyl lauryl dimethyl ammonium chloride to a conventional cationic surfactant, due to poor compatibility with anions, the agglomeration of the anionic-cationic surfactant micelles affecting the oil removal detergency. In comparative example 4, the α -hexyl- ω -hydroxypoly (oxy-1, 2-ethanediyl) was replaced by the conventional nonionic surfactant TO8, whose fast wetting function did not significantly enhance the degreasing effect; the detergent compositions prepared in the above comparative examples are significantly weaker in degreasing capacity than the examples.
2. Product stability test
The specific investigation indexes of the stability of the tableware detergent are as follows:
Stability at normal temperature: the samples were left at room temperature for 4 weeks to observe appearance;
Low temperature stability: placing the sample in a refrigerator at 0 ℃ for 4 weeks, recovering the room temperature, and observing the appearance;
High temperature stability: the sample was placed in an oven at 45 ℃ for 4 weeks, allowed to return to room temperature, and observed for appearance.
The test results are shown in Table 4.
Table 4 results of the stability test of the dishwashing detergent compositions of examples 1-4 and comparative examples 2-4
As can be seen from Table 4, the dishwashing detergent compositions of examples 1-4 of the present invention have good stability due to the good solubilization effect of the nonionic surfactant α -hexyl- ω -hydroxypoly (oxy-1, 2-ethanediyl) in the anion-cation complex system, and the effect of the positive and negative charges of the anionic and cationic surfactants can be reduced, and the micelles are not easily combined to form precipitates. In contrast, comparative examples 2-4 exhibited precipitation due to the fact that no nonionic surfactant was introduced for compounding in the cationic surfactant-containing formulation system, which was poor in compatibility, resulting in the formation of precipitates by positive and negative charge interactions of hydroxyethyl lauryl dimethyl ammonium chloride, cationic surfactant 1227, and anionic surfactant.
