Description
Technical Field
The invention relates to the field of daily chemicals, in particular to a special detergent composition for a low-foam dish washing machine.
Background
The composition of stains in daily diet is very complex, and the stains contain a large amount of starch, protein, cellulose, grease and the like. The edible vegetable oil can not be separated during the dish frying in Chinese style catering, after the high-temperature stir-frying, unsaturated fatty acid with poor chemical stability in the vegetable oil can generate a series of changes, and chain oxidation reaction can be generated on carbon-carbon double bonds, single bonds and carbon-hydrogen bonds to generate various macromolecular oxidation products, so that the viscosity of the vegetable oil is greatly increased. The sticky grease dirt is more easily combined with solid dirt such as vegetable leaves, minced meat and the like, the solid dirt is adhered to the dinner plate, and in addition, rice or wheaten food is taken as staple food by Chinese families, when tableware is not cleaned in time, the dirt is extremely easily adhered to the tableware tightly to form solid dry dirt. These dry stains are extremely difficult to remove and require significant mechanical friction to remove from the dishware.
The tableware cleaning is time-consuming and labor-consuming, the automatic dish washing machine can greatly improve the tableware cleaning efficiency, saves more time and water, and has the functions of disinfection, drying and the like besides cleaning, so the automatic dish washing machine is widely favored. Different from the surface decontamination of tableware by combining fabrics and detergents in the process of washing the dinner plate by hand, the dish washing machine washes the surface of the tableware by high-temperature and high-pressure jet water flow, the huge impact force of the water flow is added with the soaking of hot water on food residues, and the detergent special for the dish washing machine dissolved in the water flow peels off and decomposes the dirt on the surface of the tableware, thereby achieving the effects of cleaning and degerming. The mechanical force of friction decontamination in the process is realized only by water flow impact, the force is small, and the capability of removing solid dry stains tightly adhered to the surface of tableware is poor. After the automatic dishwasher finishes cleaning, if the solid dry stains are adhered to the dinner plate and cannot be completely removed, consumers can easily observe the solid dry stains by naked eyes. At present, machine washing detergents mainly depend on wetting and penetration of a surfactant and compounding of biological enzymes to break up solid dry stains, and have mild effects.
In addition, the tableware hand-washing detergent is generally rich in foam, so that a consumer can intuitively sense the amount of the foam in the hand-washing process and judge whether the addition amount of the detergent is enough or not. The surfactant plays an important role in foaming and decontamination in the process. However, in the washing process of the dish-washing machine, the dish-washing machine supplies water with certain pressure through the water pump, so that the water is sprayed out from the spray holes of the spray arm, and the recoil force is provided for the spray arm in the water spraying process to push the spray arm to rotate, thereby achieving the effects of multi-angle washing and better cleaning. Excessive foam content can cause water pump damage, overflow, spray arm speed reduction, etc. Therefore, the detergent special for the dishwasher must be low-foaming, and some anionic surfactants with strong detergency and low price cannot be applied to a washing formula. In order to control the foam quantity, most of the prior special detergents for the dish washer use nonionic surfactants to play a role in wetting, permeating and dispersing.
Therefore, the search for low-foaming cleaning solutions that significantly improve the cleaning effect of automatic dishwashers on dry solid stains is a major focus of the development of current dishwasher detergents.

Detailed Description
The following examples are given to further describe the embodiments of the present invention in detail. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
In the description herein, references to the description of the term "one embodiment," "some embodiments," "an example," "a specific example," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of an embodiment of the invention. In this specification, the schematic representations of the terms used above are not necessarily intended to refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.
The main components of the existing detergent composition for the dish-washing machine comprise a surfactant, an alkaline assistant, a chelating agent, a polymer, a bleaching agent and an enzyme preparation. The surface active agent has the functions of wetting, permeating, dispersing and the like, the alkaline auxiliary agent has the capability of saponifying grease, the chelating agent can chelate calcium ions and magnesium ions and resist the deposition of scale, the polymer has the functions of dispersing dirt and resisting the redeposition, the bleaching agent can remove colored dirt and has a certain bacterial function, and the enzyme preparation has the catalytic function and can directionally decompose the dirt. These components act synergistically in the washing process to achieve a certain cleaning effect on dishware. Wherein, in order to achieve the low-foaming effect, the adopted surfactant is generally a nonionic surfactant with poor cleaning power.
However, the solid dried stains are firmly combined with the surface of the tableware, and the hard dried stains can not be effectively cleaned only by the water flow washing of the dish washing machine and the action of the existing machine washing detergent without large mechanical impact force. If the amount of the nonionic surfactant is increased, the foam is increased, on one hand, the operation of the dishwasher is influenced, on the other hand, the mechanical force generated by water flow impact is reduced, a defoaming agent which does not contribute to the cleaning force is required, and the cleaning force and the stability of the detergent can be influenced by the additional addition of the defoaming agent.
In order to solve the problems, the embodiment of the invention provides a special low-foam detergent composition for a dish washing machine, which comprises surface active particles, wherein the particle size of the surface active particles is 1500 meshes-300 meshes, the contact angle is 60-80 degrees, and the zeta potential at the pH value of 9-11 is less than-30 mV.
The surface active particles meeting specific parameter indexes are added into the detergent composition, so that the detergent composition has emulsifying and dispersing capabilities, has a certain cleaning effect, does not generate foam, does not need to be added with a defoaming agent, and does not remain in a dish-washing machine. In addition, the surface active particles can improve the mechanical friction of water flow on the surface of tableware in the washing process of a dishwasher and enhance the cleaning efficiency of the detergent. Thereby realizing low foaming and strong decontamination capability.
According to some embodiments of the invention, the surface active particles are one or more of modified clay-like particles, cellulose nanocrystals, cellulose nanofibers.
According to some embodiments of the invention, the modification method comprises electrostatic adsorption and ion exchange. Taking montmorillonite particles as an example, the modification method can adopt the following operations: montmorillonite and polysaccharide such as sodium alginate are subjected to electrostatic adsorption, and the montmorillonite and organic ammonium surfactant are subjected to cation exchange reaction to obtain modified montmorillonite; wherein, the proportion of polysaccharide and montmorillonite, the type of organic ammonium and the proportion of montmorillonite are adjusted to obtain montmorillonite granules with different contact angles and potentials, and the montmorillonite granules with different sizes are obtained by grinding and sieving. It will be appreciated that the skilled person will know how to obtain other surface-active particles given the above-described montmorillonite modification process.
According to some embodiments of the invention, the surfactant particle is present in the detergent composition in an amount of from 1 to 25% by weight.
It will be appreciated that less surfactant particles will not provide good stain removal, but not more. The present inventors have found that it is preferable to control the concentration of the compound within the range of 1 to 25%, for example, 1%, 2%, 5%, 10%, 15%, 20% or 25%. Further, the weight percentage of the surface active particles in the detergent composition is 2-15%.
According to some embodiments of the invention, the detergent composition further comprises 1-25% by weight of a suspension dispersant, wherein the suspension dispersant is one or more of acrylic acid homopolymer and acrylic acid maleic acid copolymer, and the molecular weight of the suspension dispersant is 4500-80000.
The conventional detergent composition is also added with a suspension dispersant properly to uniformly disperse each component of the detergent, and after the surface active particles are used, the aggregation and sedimentation are more likely to occur, so that the specific suspension dispersant needs to be selected to ensure that the dispersing effect is better. Experiments show that the acrylic acid homopolymer and the acrylic acid maleic acid copolymer with the molecular weight of 4500-80000 have better effects, and other molecular weights and other types of suspension dispersants have unsatisfactory effects.
According to some embodiments of the invention, the detergent composition further comprises 0.1-1.5% by weight of a surfactant which is a nonionic surfactant selected from one or more of ethylene oxide and propylene oxide block copolymers, fatty alcohol alkoxylates, fatty acid alkoxylates, ethoxylated fatty acid methyl esters.
After the surface active particles are adopted, the dosage of the nonionic surfactant can be reduced from about 3-15% of the conventional dosage to not more than 0.1%.
According to some embodiments of the invention the detergent composition further comprises 2-30% by weight of a chelating agent, said chelating agent being one or more of citric acid, gluconic acid, glutamic diacetic acid, methylglycinediacetic acid, ethylenediaminetetraacetic acid, hydroxyethylidene-diphosphonic acid and alkali metal or ammonium salts thereof.

According to some embodiments of the invention, the detergent composition further comprises 0.01-5% by weight of an enzyme preparation comprising one or more of protease, amylase, cellulase, lipase, pectinase, mannanase. For example, the protease may be a mixture of protease and amylase, or a mixture of amylase and pectinase, at an arbitrary mixing ratio.
According to some embodiments of the invention, the detergent composition further comprises 2-30% by weight of a filler, the filler being one or more of a sulfate, sodium chloride.
According to some embodiments of the invention, the detergent composition further comprises 0.01-20% by weight of other auxiliaries, including one or more of pigments, perfumes, antifoaming agents, pH regulators, corrosion inhibitors.

As can be seen by combining the cleaning effect scores of examples 5 to 7 and comparative examples 11 to 13 in the table above, the detergent product prepared by the raw material ratio of the invention has more obvious cleaning effect on solid dry stains. In addition, the addition of the surface active particles has a remarkable effect on removing solid dry stains, but the larger the addition amount is, the better the addition amount is, and the addition amount is preferably 1 to 25 percent.
And (3) testing the foam quantity:
the dynamic foam is measured by an SITA R-2000 dynamic foam instrument. The dynamic foam measuring process is divided into a foaming stage and a defoaming stage. A detergent solution with a concentration of 0.2% was prepared, and during the foaming phase, the apparatus was agitated once every 10 seconds at 500rpm, the volume of foam was determined, 16 measurements were made, and the amount of foam was recorded repeatedly. And a defoaming stage, wherein the foam volume of standing is measured every three minutes and is repeatedly recorded for 6 times. In the test comparison of examples, the last recorded foaming amount (i.e., 16 th foaming amount) was taken as the final foaming amount, and the last recorded foaming amount at the defoaming stage (i.e., 6 th foaming amount) was taken as the final defoaming amount.
The results are shown in Table 8.
TABLE 8
As can be seen by combining the dynamic foam measurement results of the above examples 5-7 and comparative examples 11-13, the detergent product prepared by the raw material ratio of the invention has lower foam amount, and after the surfactant particles are added, the addition amount of the surfactant in the detergent is lower and the foam is lower.
Finally, it should be noted that the above embodiments are only for illustrating the present invention, and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalents may be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention, and the technical solution of the present invention is covered by the claims of the present invention.
