Description
Technical Field
The invention relates to the technical field of daily chemical products, in particular to a stable concentrated liquid detergent composition, a preparation method thereof and a washing bead.
Background
In various liquid detergent products for fabrics in the market, concentrated liquid detergents are more and more popular among consumers, manufacturers and retailers because the concentrated liquid detergents have the advantages of convenience in use, suitability for mechanical washing processes and the like, are flexible in formula, simple in process, energy-saving and environment-friendly, and can effectively control and reduce the storage, packaging and transportation costs. At present, a new generation of laundry products, namely laundry beads, appears on the market, namely liquid detergent is packaged in a water-soluble film, the products do not need to contact with the detergent when being used, one or two laundry products are used at a time according to the amount of clothes, and the laundry beads are not splashed when being used and are very convenient, so the laundry beads are favored by consumers on the market. The packaging film of the laundry gel beads mainly adopts polyvinyl alcohol (PVA), and in order to ensure that the water-soluble polymer PVA cannot be dissolved due to overhigh water content, a concentrated liquid detergent with low water content is required to be adopted (the water content of a conventional liquid detergent is usually more than 30%). In addition, the concentrated liquid detergent has the advantages of convenient use, suitability for mechanical washing process and the like, is flexible in formula, simple in process, energy-saving and environment-friendly, can effectively control and reduce the storage, packaging and transportation costs, and is more and more favored by consumers, manufacturers and retailers.
One of the problems that concentrated liquid detergents must address is how to prevent the formation of surfactant gels. Surfactants include ionic surfactants, nonionic surfactants and zwitterionic surfactants, and among them, alkylbenzene sulfonates (such as sodium dodecylbenzenesulfonate) in anionic surfactants have the advantages of excellent cleaning effect and low cost, so most liquid detergents are favored to use alkylbenzene sulfonates as anionic surfactants for dual purposes of cleaning and cost control.
It is known in the art to effectively prevent surfactant gelation by controlling the water content and adding a solubilizer to the product to change the morphology of the surfactant micelles to form more mobile, more soluble spherical or rod-like micelles from the liquid crystal phase. The solubilizer comprises an organic solvent and a cosolvent, wherein the organic solvent comprises ethanol, propylene glycol, glycerol, dipropylene glycol n-butyl ether, ethoxylated benzyl alcohol and the like. However, because the ionic surfactant has relatively low solubility in the organic solvent, the ionic surfactant is very likely to precipitate after supersaturation with the increase of the content of the organic solvent and the decrease of the water content in the composition, so that the product is remarkably layered, the stability of the product is affected, and the use feeling of consumers is poor. Therefore, in order to prevent the surfactant from gelling in a concentrated detergent containing alkylbenzene sulfonate-anionic surfactant, it is necessary to control the water content and add a solubilizer, i.e., an organic solvent, but as the water content decreases and the organic solvent increases, the anionic surfactant precipitates, which affects the product stability, which are two contradictory problems.
In order to solve the technical problem of controlling the water content to prevent the gelation of the anionic surfactant and inhibit the precipitation and delamination of the anionic surfactant, researchers add a suspending agent or a structuring agent into the detergent, but the additives are expensive, cannot bring remarkable cleaning or nursing functions to the washed fabrics, and are difficult to apply in actual production. As a technical improvement, small-molecular organic amine is generally selected as an alkaline neutralizing agent to replace the alkaline neutralizing agent in the industry, such as monoethanolamine, triethanolamine and the like, and is used for neutralizing an anionic surfactant in an acidic state. However, the addition of the organic amine also causes a new problem in that the organic amine is easily oxidized to cause significant yellowing of the product, which seriously affects the appearance of the product during the shelf life.
Thus, it is a significant challenge to formulate low moisture concentrated detergent products, such as alkyl benzene sulfonate-anionic surfactants, without neutralizing with organic amines, and to obtain products with high stability (neither gelling nor precipitation demixing).
Disclosure of Invention
It is an object of the present invention to provide a stable concentrated liquid detergent composition containing an alkylbenzene sulfonate, which is free from the technical problems of neither gelation nor precipitation delamination at a low water content, and which is excellent in stability and free from yellowing in appearance, and a process for producing the same, in view of the disadvantages of the prior art.
It is a further object of the present invention to provide a laundry bead having low moisture content and high stability in view of the deficiencies of the prior art.
The purpose of the invention is realized by the following technical scheme:
there is provided a stable concentrated liquid detergent composition comprising an anionic surfactant, said anionic surfactant comprising an alkylbenzene sulfonate; the composition comprises the following components in percentage by weight of the total composition:
wherein:
the water comprises water brought in by the raw materials, water generated by the neutralization reaction and additionally added water;

the weight percentage of the organic amine with the relative molecular weight of less than 200 in the composition is less than 0.1 percent.
In the above technical scheme, the composition comprises the following components in percentage by weight of the total amount of the composition:
in the technical scheme, the mass ratio of the alkylbenzene sulfonate to other anionic surfactants in the anionic surfactants is 1: 10-1: 1.

In the above technical solution, the non-aqueous solvent without amino functional group is at least one of monohydric alcohol, dihydric alcohol, trihydric alcohol, alcohol ether solvent and polyethylene glycol with a relative molecular weight of less than 400.
In the above technical scheme, the alkaline neutralizing agent is an inorganic alkaline neutralizing agent, and the cation of the inorganic alkaline neutralizing agent is at least one selected from ammonium ions, sodium ions, potassium ions, calcium ions and magnesium ions; the anion is selected from at least one of hydroxide, oxide, carbonate and bicarbonate. Preferably, the alkaline neutralizing agent is at least one selected from the group consisting of sodium hydroxide, potassium carbonate, sodium bicarbonate, and sodium carbonate.
The present invention also provides a process for the preparation of a stable concentrated liquid detergent composition as defined above, comprising the steps of:
1) adding an alkaline neutralizing agent and deionized water into the main preparation tank, and stirring until the alkaline neutralizing agent and the deionized water are completely dissolved;
2) then adding a non-aqueous solvent without amino functional groups, and stirring until the mixture is completely dissolved;
3) adding an anionic surfactant, and stirring until the anionic surfactant is completely dissolved;
4) adding other surfactants and additives, supplementing a non-aqueous solvent, and stirring until the surfactant and the additive are completely dissolved, so that the appearance is uniform;
5) adjusting the quality parameters of the product, adjusting the pH value to 5.0-10.0, and stirring until the appearance is uniform.
The invention also provides a laundry bead, which comprises a content and a water-soluble film for coating the content, wherein the content is the concentrated liquid detergent composition.
The invention has the beneficial effects that:
the stable concentrated liquid detergent composition contains an alkylbenzene sulfonate anionic surfactant in the formula to ensure that the liquid detergent has excellent washing and cleaning effects, and the components in percentage by weight are as follows: 0.1-10% of alkaline neutralizing agent, 30-70% of total surfactant, 10-50% of non-aqueous solvent without amino functional group, 0.01-20% of additive and 0.1-15% of water; wherein, the water comprises water brought in the raw materials, water generated by neutralization reaction and additionally added water, and the total amount is controlled to be 0.1-15 percent, so as to prevent the surfactant from gelling and facilitate production and use; but simultaneously, because the water content is very low, the problem that the anionic surfactant is easy to precipitate and separate out along with the increase of the content of the non-aqueous solvent is solved by strictly controlling the mass ratio of the alkylbenzene sulfonate to other anionic surfactants in the anionic surfactant to be 1: 20-1.2: 1 and not using organic amine as an alkaline neutralizer (the weight percentage of the organic amine with the relative molecular weight of less than 200 in the composition is less than 0.1 percent), the technical problem that the surfactant can not be gelatinized and can not be precipitated and layered is solved, the invention avoids the adoption of organic amine in the prior art, does not cause product appearance yellowing, is beneficial to prolonging the shelf life of the product and better improves the use experience of consumers. Therefore, the concentrated liquid detergent disclosed by the invention has the advantages of simple production process, easiness in packaging, storage and transportation, convenience in use, energy conservation, environmental friendliness and good cleaning effect, and can obtain high stability under the conditions that the water content in the formula is extremely low and organic amine is not adopted, so that the concentrated liquid detergent has a very good market application prospect.

The following preparation methods were used for the concentrated liquid detergent compositions of examples 1 to 9 and the detergent compositions of comparative examples 1 to 7, except that the formulation components and the ratio of the amounts thereof were different:
1) adding an alkaline neutralizing agent and deionized water into the main preparation tank, and stirring until the alkaline neutralizing agent and the deionized water are completely dissolved;
2) then adding a non-aqueous solvent without amino functional groups, and stirring until the mixture is completely dissolved;
3) adding an anionic surfactant, and stirring until the anionic surfactant is completely dissolved;
4) adding other surfactants and additives, supplementing a non-aqueous solvent, and stirring until the surfactant and the additive are completely dissolved, so that the appearance is uniform;
5) adjusting the quality parameters of the product, adjusting the pH value to 5.0-10.0, and stirring until the appearance is uniform.
The detergent compositions of examples 1 to 9 and comparative examples 1 to 7 were divided into two groups, and the storage appearance was subjected to stability tests, respectively, according to the following specific test methods and criteria:
high-temperature stability: after bottling and sealing the composition, placing the composition in an environment with the temperature of 45 +/-1 ℃, after placing the composition for 1 month at constant temperature, recovering to the room temperature of 25 +/-5 ℃, and ensuring that the appearance of the composition has no obvious change, such as no layering or precipitation, and the high-temperature stability is qualified.
Low-temperature stability: the composition is bottled and sealed, then placed in an environment with the temperature of 0 +/-2 ℃, placed at constant temperature for 1 month, taken out and immediately observed. The appearance of the composition has no obvious change, such as no layering or precipitation, and the composition is qualified for low-temperature stability.
Freeze-thaw cycle stability: placing the mixture in an environment with the temperature of-15 ℃ to-20 ℃, taking out the mixture after placing the mixture for 24 hours at constant temperature, placing the mixture in an environment with the temperature of 25 +/-5 ℃ at room temperature for 24 hours, circulating for one time, continuously circulating for five times, observing the state of the composition every time, wherein the experiment is a freeze-thaw cycle experiment. The appearance of the composition has no obvious change, such as no layering or precipitation, and the freeze-thaw cycle stability is qualified.
And (3) normal temperature stability: after the composition is bottled and sealed, the composition is placed in a room temperature environment (20-30 ℃) and placed for 1 month, the appearance of the composition has no obvious change, such as no layering or precipitation, and the stability at normal temperature is qualified.
Color stability: high temperature stability test samples, color contrast to the original samples.
Stability control test of the first group of detergent compositions:
the ingredients and amounts of the components in the detergent compositions of examples 1 to 2 and comparative examples 1 to 6, and the results of the stability test are shown in table 1.
Stability control test of the second detergent composition:
the ingredients and amounts of the components in the detergent compositions of examples 3 to 9 and comparative example 7, and the results of the stability test are shown in table 2.
TABLE 1 detergent compositions of examples 1-2 and comparative examples 1-6
As can be seen from table 1, although the compositions of comparative examples 1, 3 and 5 have a higher stability due to neutralization with organic amine (triethanolamine) even though the mass ratio of alkylbenzene sulfonate to other anionic surfactants is greater than 1, the color of the compositions neutralized with organic amine (triethanolamine) in the above comparative examples is severely changed after high temperature stability test, because the appearance color is severely changed due to the organic amine, which seriously affects the appearance of the product.
In the same proportions, the compositions of comparative examples 2, 4 and 6, neutralized with sodium hydroxide, resulted in delamination and failed to form stable compositions.
In contrast, the compositions of examples 1 and 2, although the sodium hydroxide of comparative example 2 was used for neutralization, were formed into compositions having high stability and a low water content of 10% or less because the mass ratio of the alkylbenzene sulfonate to the other anionic surfactant in the compositions was controlled to be less than 1. Thus, the present invention is directed to low moisture concentrated detergent products containing alkylbenzene sulfonate-anionic surfactants, which are formulated without organic amine neutralization to achieve high stability (neither gelation nor precipitation delamination).
TABLE 2 detergent compositions of examples 3-8 and comparative example 7
As is clear from Table 2, the detergent compositions of examples 3 to 9 each contain one or more alkaline neutralizers each composed of sodium hydroxide, potassium hydroxide, sodium bicarbonate and ammonium hydroxide, and thus have high stability. The cleaning composition of comparative example 7 required the use of an organic amine (monoethanolamine) for stabilization, but the color changed significantly after the high temperature stability test. It is because comparative example 7 uses organic amine, which seriously affects the appearance stability of the product.
The following concentrated liquid detergent compositions of examples 10 to 11 and the detergent compositions of comparative examples 8 to 9 were prepared by the method of example 1, except that:
the detergent composition is added into an automatic washing bead packaging machine, a water-soluble film (PVC) is adopted for packaging, and a liquid-tight small bag is formed by sealing to obtain the washing beads.
The prepared washing gel beads are respectively subjected to stability test, and the specific method is as follows:
putting the washing gel beads into a sealed bag, placing the sealed bag in an environment with the temperature of 45 +/-1 ℃, after placing the sealed bag at constant temperature for 1 week, recovering the temperature to the room temperature of 25 +/-5 ℃, and ensuring that the appearance of the gel beads has no obvious change, such as no layering or precipitation, and the stability is qualified.
The ingredients and amounts of the components of the detergent compositions of examples 10-11 and comparative examples 8-9, and the results of the stability performance test of the laundry beads prepared using the above-described detergent compositions, respectively, are shown in table 3.
TABLE 3 detergent compositions of examples 10-11 and comparative examples 8-9
As can be seen from table 3, the detergent compositions of examples 10 to 11 are different from those of comparative examples 8 to 9 in water content, and it is apparent that when the water content of comparative examples 8 to 9 is more than 15%, a liquid leakage phenomenon occurs due to significant dissolution of the water-soluble film. Therefore, the water content of the detergent composition of the present invention is controlled to be 15% or less.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
