Description

Technical Field

[0001] The invention relates to the field of daily chemical products, in particular to a dishwasher detergent and dishwashing condensate beads for the dishwasher. Background Art

[0002] In recent years, with the improvement of living standards and the acceleration of the pace of life, household dishwashers, as representatives of "lazy home appliances" and "healthy home appliances", have attracted the attention of more and more families. Compared with traditional tableware washing methods, household dishwashers can save manpower and time, reduce water waste, and have functions such as washing, rinsing, disinfecting and drying tableware, which can fully meet people's needs to be liberated from simple and repetitive housework.

[0003] The working principle of common dishwashers is to use high-temperature and high-pressure water flow to mechanically flush the surface of tableware 360 ​​degrees, and the detergent saponifies and decomposes the oil and residue on the surface of the tableware, and the hot water soaks and swells the food residue, so that the oil and residue are quickly decomposed and removed, and the dual effects of cleaning and sterilization are achieved. At present, the common dishwasher detergents on the market mainly include dishwashing liquid, dishwashing powder, dishwashing blocks, dishwashing beads, etc. Among them, dishwashing powder, dishwashing blocks, and dishwashing liquid have relatively low active content due to dosage form restrictions, and cannot meet the increasing cleaning needs of consumers. Therefore, the cavity / multi-cavity dishwashing beads solve this problem to a certain extent.

[0004] However, the dishwashing gel beads currently sold on the market mainly remove common dirt, and the formula is not targeted. The removal effect of some special stains such as lipstick and other waxy and heavy oil stains is still unsatisfactory. Lipstick contains high levels of heavy metals such as lead and cadmium. Long-term inhalation of human body may lead to chronic poisoning, causing anemia, abdominal pain, acute renal failure and brain neuropathy. Lanolin easily absorbs dust, bacteria and viruses in the air, causing health risks. Artificial pigments, under ultraviolet radiation, may be converted into mutagens and cause cancer. Therefore, if lipstick is not washed clean, it will not only affect the appearance of tableware, but also bring health risks to consumers. However, there are strong intermolecular forces (van der Waals forces, intermolecular hydrogen bonds, etc.) between lipstick and the surface of tableware, making it difficult to peel lipstick from the surface; in addition, the main component of lipstick is wax, and its melting point is higher than the washing temperature (55-65°C), such as carnauba wax, melting point: 80-86°C, candelilla wax, melting point: 66-69°C, etc., so it remains solid during washing, insoluble, and difficult to remove. Summary of the invention

[0025] The following examples are used to illustrate the present invention, but they are not intended to limit the scope of the present invention.

[0026] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiment of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0027] It is very common for modern women to use lipstick, but the dishwashing gel beads currently sold on the market mainly remove common dirt through alkaline additives, oxidants and low-foaming non-ionic surfactants. The removal effect of waxy and heavy oil stains such as lipstick is still unsatisfactory. Lipstick contains high levels of heavy metals such as lead and cadmium. Long-term inhalation of human body may lead to chronic poisoning, causing anemia, abdominal pain, acute renal failure and brain neuropathy. Lanolin easily absorbs dust, bacteria and viruses in the air, causing health risks. Artificial pigments, under ultraviolet radiation, may be converted into mutagens and cause cancer. Therefore, if lipstick is not washed clean, it will not only affect the appearance of tableware, but also bring health risks to consumers. However, there are strong intermolecular forces (van der Waals forces, intermolecular hydrogen bonds, etc.) between lipstick and the surface of tableware, making it difficult to peel lipstick from the surface; in addition, the main component of lipstick is wax, and its melting point is higher than the washing temperature (55-65°C), such as carnauba wax, melting point: 80-86°C, candelilla wax, melting point: 66-69°C, etc., so it remains solid during washing, insoluble, and difficult to remove.

[0028] According to the dishwasher detergent of an embodiment of the present invention, the detergent contains a surfactant, and the surfactant includes surfactant A, surfactant B and surfactant C. The surfactant A is selected from one or more of fatty alcohol alkoxylates, and its weight accounts for 10-30% of the surfactant. The surfactant B is long-chain carboxylic acid ester polyoxyethylene-18, and its weight accounts for 20-40% of the surfactant. The surfactant C is selected from one or more of amino oleic acid esters, and its weight accounts for 20-40% of the surfactant.

[0029] Dishwashers use high-temperature and high-pressure water to wash tableware in three dimensions and in all directions, and detergents decompose the oil and residue on the surface of tableware. In addition, hot water soaks and expands the food residues, which quickly decomposes and falls off the oil and residues, ultimately achieving a cleaning effect. Due to the limitations of the working principle of dishwashers, in order to protect the water pump, prevent overflow, and prevent excessive foam from affecting the rotating light of the washing arm during machine washing, dishwasher-specific detergents must be low-foam or even foam-free. Surfactants in machine-specific detergents play a more surface wetting role. Therefore, it is difficult for current dishwasher detergents to remove waxy solid heavy oils such as lipstick.

[0030] The present invention has found that the above-mentioned surfactant A, surfactant B and surfactant C are reasonably matched to achieve wetting and good decontamination effect under the condition of low foaming. Surfactant A is a fast emulsifier; surfactant B is a long-chain carboxylic acid ester polyoxyethylene-18, which is an 18-carbon fatty acid ester, and the ester molecular structure is similar to the structure of oils and waxes. According to the principle of similar compatibility, it has a strong dissolving and removing ability for oils, mineral oils and paraffin waxes. It has a very reasonable double bond structure and has good dispersing and removing power for lipids; surfactant C is similar to the fatty acid structure in oleic acid and animal and vegetable oils, and can adsorb and dissolve hydrophobic groups in dirt. At the same time, amine and alcohol amine groups are hydrophilic groups, which can peel off oil dirt from the matrix.

[0031] According to some embodiments of the present invention, the weight percentage of the surfactant in the cleaning agent is 5-30%, and more preferably 7-20%.

[0032] According to some embodiments of the present invention, the surfactant A is selected from one or more of the following compounds of the general formula: Wherein, n is 2-16 and is a positive integer; m is 2-10 and is a positive integer; x is 0-10; y is 0-10; and z is 0-10.

[0033] According to some embodiments of the present invention, the surfactant C is one or more of triethylamine oleate, ethylenediamine oleate, and triethanolamine oleate soap.

[0034] In some embodiments of the present invention, the surfactant A is selected from one or more of the following compounds of the general formula: Wherein, n is 2-8 and is a positive integer; m is 2-6 and is a positive integer; x is 2-5; y is 0-3; z is 0-3;

[0035] The surfactant B is long-chain carboxylate polyoxyethylene-18;

[0036] The surfactant C is ethylamine oleate.

[0037] Under the above preferred combination, the obtained cleaning agent can remove waxy and oily dirt more effectively and has better low foaming property.

[0038] According to some embodiments of the present invention, the cleaning agent further contains an alkaline auxiliary agent, in which the oxygen content of the alkaline auxiliary agent accounts for 20-50% by weight of the cleaning agent; the alkaline auxiliary agent is one or more of sodium carbonate, potassium carbonate, sodium hydroxide, potassium hydroxide, sodium bicarbonate, and sodium silicate.

[0039] The alkaline additive has the ability to saponify oils and fats. The amount of the alkaline additive used in the present invention is more than that in conventional methods. The purpose of this is to - It reacts with oils and fats to produce water-soluble fatty acid salts to remove grease and dirt.

[0040] According to some embodiments of the present invention, the cleaning agent further contains 1-20% of an oxidant by weight, and the oxidant is selected from one or more of alkali metal and alkaline earth metal peroxides, hydrogen peroxide, peroxy acid salts and organic peroxides.

[0041] According to some embodiments of the present invention, the cleaning agent further contains 0.1-30% of a polymer by weight, the polymer being selected from homopolymer / copolymer high molecular weight compounds containing at least one of carboxyl, alkyl, sulfonic acid, amino, and hydroxyl groups in the molecular structure, and having a molecular weight between 500 and 10000. The polymer has the effects of dispersing stains and preventing redeposition.

[0042] According to some embodiments of the present invention, the cleaning agent further contains, by weight percentage, 0.1-40% of an amino acid derivative chelating agent, and the amino acid derivative chelating agent includes one or more of methylglycine diacetic acid, glutamic acid diacetic acid, N,N-dicarboxylic acid amino-2-hydroxypropane sulfonic acid, 3-hydroxy-2,2'-imidyl disuccinic acid and its alkali metal salts or ammonium salts.

[0043] Chelating agents can chelate calcium ions and magnesium ions and resist scale deposition. The present invention uses amino acid derivative chelating agents because automatic dishwasher detergents not only need to cope with hard water of different hardness, but also must be environmentally friendly. Under the requirement of being phosphorus-free and considering the negative effects of EDTA and NTA on the environment and human body, amino acid derivative chelating agents are undoubtedly the best choice. From the perspective of cleaning mechanism, in order to remove tableware grease and various stains, it is necessary to be able to effectively remove the "calcium bonds" that bind grease and stains. In this regard, amino acid derivative chelating agents have the strongest ability to chelate "calcium" among biodegradable chelating agents.

[0044] According to some embodiments of the present invention, the cleaning agent further contains 0.02-30% of an enzyme preparation by weight, wherein the enzyme preparation comprises one or more of protease, α-amylase, lipase, esterase, cellulase, mannanase, and reductase. The enzyme preparation has a catalytic effect and can decompose stains in a targeted manner.

[0045] According to some embodiments of the present invention, the cleaning agent further contains one or more of a corrosion inhibitor, a pigment, a defoaming agent, a pH regulator, an antibacterial agent, a preservative, colored particles, a flavor, and a filler.

[0046] Among them, the defoaming agent is preferably a polysiloxane defoaming agent, including one or more of dimethylsiloxane, phenylsiloxane, and amino-terminated siloxane.

[0047] The pigments include dyes and pigments and may be all pigments permitted for use in detergent products in the art, suitable examples being acid scarlet G, basic fuchsin, acid golden yellow G, acid tender yellow G, basic egg yolk, direct fast blue B2RL, indigo and the like.

[0048] According to some embodiments of the present invention, the cleaning agent comprises the following components by weight percentage:
