Along with the improvement of living standard of people, the requirements of people on liquid washing products are higher and higher. Concentrated detergents, which are highly detersive, easy to rinse, and of a certain viscosity, are most popular with consumers today.
Polyether nonionic surfactants, such as fatty alcohol polyoxyethylene ether series, alkylphenol polyoxyethylene ether series, isomeric alcohol polyoxyethylene ether series, alkyl polyoxypropylene ethylene block polyether series, and the like, are commonly used in liquid detergents. Wherein, the fatty alcohol polyoxyethylene ether-9 (AEO-9) has the advantages of high-efficiency decontamination, low price and the like, and is one of the polyether nonionic surfactants with the largest dosage at present.
Concentrated detergents are popular in the market due to their low usage, ease of packaging and shipping, high surfactant concentration, and generally detergents having a surfactant content above 40wt% can be defined as concentrated detergents.

Disclosure of Invention
The object of the present invention is to provide a highly concentrated detergent containing a comb polyether composition. The high-concentration detergent has strong detergency, is easy to rinse, has high stock solution viscosity, basically keeps the viscosity unchanged or even higher even after being diluted by water by 3-4 times, and gives consumers the visual feeling of 'super-concentration' and excellent washing performance.
The technical scheme of the invention is as follows: a highly concentrated detergent containing a comb polyether composition comprises 20-35wt% of the comb polyether composition and 1.5-6.0wt% of sodium chloride.
In the high-concentration detergent containing the comb-shaped polyether composition, 20-40wt% of a surfactant is also contained.
In the high-concentration detergent containing the comb-shaped polyether composition, the surfactant is one or more of alkylbenzene sulfonic acid, fatty acid methyl ester ethoxy condensate, alcohol ether and alpha-alkenyl sodium sulfonate.
In the high-concentration detergent containing the comb-shaped polyether composition, the surfactant consists of 8-15wt% of alkylbenzene sulfonic acid and 10-30wt% of fatty acid methyl ester ethoxy condensate.
In the high-concentration detergent containing the comb-shaped polyether composition, the concentrated detergent composition further comprises one or more of a pH regulator, a pigment, a preservative, a perfume and a solubilizer.
In the above-described highly concentrated detergent containing comb polyether composition, the amount of water in said concentrated detergent composition is less than 45% by weight.
In the high-concentration detergent containing the comb-shaped polyether composition, the comb-shaped polyether composition is composed of polyether type nonionic surfactant and comb-shaped polyether.
The comb-shaped polyether composition contains 40-70% of comb-shaped polyether.
In the invention, the comb-shaped polyether composition is described in Chinese patent application CN201510474783.1, discloses a comb-shaped polyether composition, a manufacturing method thereof and a liquid detergent applying the comb-shaped polyether composition, and the structural formula of the polyether nonionic surfactant is R1(CH2CH2O)m(CHCH3CH2O)n(OCH2CH2O)x(CHCH3CH2O)yH，R1＝HO,CH3O,C8～20H16～41O,C8～20H16～41N(CH2CH2O)ZH(CH2CH2O),C8～20H16～41(C6H4) O; m is 0-50, n is 0-50, x is 0-100, y is 0-100, and z is 1-60; the comb-shaped polyether is formed by copolymerizing at least one hydrophilic alkenyl monomer and at least one alkenyl polyether, wherein the molecular formula of the alkenyl polyether is as follows: r2R3C＝CR4R5(ii) a Wherein R is2、R3、R4、R5At least one of which contains a polyether segment.
In the highly concentrated detergent containing the comb-shaped polyether composition, the highly concentrated detergent has a pH of 6.5 to 8.5.
The preparation method of the high-concentration detergent containing the comb-shaped polyether composition comprises the following steps: dispersing the raw materials into water, stirring and dispersing, and then adjusting the pH value of the system to be proper.
The invention has the following beneficial effects:
the comb-shaped polyether composition is used as an important component in a high-concentration detergent, and can effectively ensure that the concentrated detergent can keep better viscosity under the condition of being diluted by 4 times.
In the course of the experiments, it was surprisingly found that a very good viscosity retention is achieved when the concentration of comb polyether composition in the concentrated detergent is above 20%, whereas the effect is significantly reduced as soon as the concentration of comb polyether composition is below 20%. When the concentration of the comb-shaped polyether is more than 20%, the intermolecular distance of the polymer is shortened, and the main chain of the molecule is negatively charged, so that the intermolecular repulsion is increased, the molecules are highly curled, the hydrophilic polycarboxylic acid main chain faces outwards, the hydrophobic fatty alcohol polyether side chain at the tail end faces inwards and is contained in a high-molecular coil, and the thickening mechanism of the system is mainly the space filling of the high-molecular coil and the synergistic thickening effect among small-molecular surfactants caused by the hydrophilic effect of the polycarboxylic acid main chain. As the system is diluted by water, the molecular distance between comb-shaped polyether molecules is increased, the molecular terminal distance is increased, the chain segment is stretched, the fatty alcohol polyether side chain participates in the synergistic action among the surfactants, and the thickening mechanism of the system mainly comprises the movement resistance of a polymer molecular chain and the synergistic thickening action among the surfactants with the participation of comb-shaped polyether. Especially, the comb-shaped polyether can form a large-size micelle due to the synergistic thickening effect, so that the comb-shaped polyether has strong thickening capability and can compensate viscosity reduction caused by dilution.
The concentrated detergent composition of the present invention also has the advantage that it maintains a low pour point and eliminates gelling; meanwhile, the addition of the comb-shaped polyether composition with high concentration does not influence the washing effect of the detergent after dilution, and the comb-shaped polyether composition keeps good detergency and has less foam.
As a further improvement of the present invention, the remaining surfactant of the present invention is preferably a combination of alkylbenzene sulfonic acid and fatty acid methyl ester ethoxy condensate, and the combination is in the sense of providing a good synergistic thickening effect with comb polyether, and meanwhile, the alkylbenzene sulfonic acid and fatty acid methyl ester ethoxy condensate also has the advantages of good washing effect and less foam, and can further improve and enhance the washing effect of the detergent of the present invention and reduce foam generation.
Detailed Description
The technical solution of the present invention will be described in further detail with reference to the following embodiments, but the present invention is not limited thereto.
Example 1:
part of sodium hydroxide is dissolved in water, then the concentrated detergent is prepared according to the formula amount by adopting the conventional detergent preparation method and feeding sequence in the prior art, and finally the pH value of the system is adjusted to the target pH value by using a proper amount of sodium hydroxide solution.
The specific dosage of each component is as follows:
alkyl benzene sulfonic acid: 15g of the total weight of the mixture;
10g of fatty acid methyl ester ethoxy condensate (FMEE);
comb polyether composition: 21g of a basic amine;
sodium chloride: 2g of the total weight of the mixture;
propylene glycol: 9g of a mixture;
sodium hydroxide: proper amount;
pigment: proper amount;
preservative: 0.2 g;
essence: 0.4 g;
water was added to 100 g.
Examples 2-6 and comparative examples 1 and 2 were prepared as in example 1, and the following formulation was found in table 1:
table 1: formulation tables for examples 1-6 and comparative examples 1 and 2
Methods for preparing comb polyether compositions of examples 1-6 and comparative example 1 of the present invention reference is made to CN201510474783.1 to disclose a comb polyether composition, a method for preparing the same, and a method for preparing the same of example 2 described in the specification, wherein the concentration of comb polyether is adjusted by the amount of nonionic surfactant used in example 2.
The results of the tests of the above examples and comparative examples are shown in Table 2 below, and the detergency is tested according to QB/T1224-2012:
table 2: test results of examples 1 to 6 and comparative examples 1 and 2
As can be seen from table 2 above, the comb polyether compositions of the present invention are feasible for use in concentrated detergents. At the same time, it is very important that the applicant has found during the experimental work that the amount of comb polyether composition is not freely selectable, as an unexpected result, when the amount of comb polyether composition is greater than 20 wt%, the disadvantage of excessive dilution of conventional concentrated laundry detergents is drastically changed.
Of these, the combination of the sodium α -olefin sulfonate, the alkylbenzenesulfonic acid and the comb-shaped polyether composition in example 6 showed more excellent viscosity performance, and the combination showed more remarkable viscosity-increasing effect and maintained higher viscosity after dilution as in example 4 with the same amount of the surfactant.
The above description is only exemplary of the invention, and any modification, equivalent replacement, and improvement made within the spirit and scope of the present invention should be considered within the scope of the present invention.
