Description

Technical Field

[0001] The invention relates to the field of daily chemical products, in particular to an automatic dishwasher detergent and dishwashing condensate beads for the automatic 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 effect of removing some special stains such as hot pot heavy oil stains is still unsatisfactory. Hot pot heavy oil stains represented by beef hot pot base contain a large amount of animal fats such as beef tallow and lard, and the melting point is above 40°C. The initial cold water pre-washing basically cannot rinse away the residual oil stains. The current dishwasher-specific detergents are difficult to completely remove this type of hot pot heavy oil stains in standard wash, energy-saving wash, super-fast wash and other modes, with low main wash temperature and short time. In addition, there are many kinds of spices in hot pot bases, which are difficult to clean and have residual odor. Summary of the invention

[0026] Figure 1 This is a photo of the cleaning power of hot pot heavy oil tested under the standard washing procedure of the present invention. DETAILED DESCRIPTION

[0027] The following examples are used to illustrate the present invention, but they are not intended to limit the scope of the present invention.

[0028] 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.

[0029] According to the automatic dishwasher detergent of the embodiment of the present invention, the detergent contains a surfactant and a deodorizing aid, 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 20-40% of the surfactant, the surfactant B is long-chain carboxylic acid ester polyoxyethylene-18, and its weight accounts for 15-35% of the surfactant, and the surfactant C is selected from one or more of amino oleic acid esters, and its weight accounts for 10-30% of the surfactant.

[0030] The dishwasher uses high-temperature and high-pressure water to wash the tableware in three dimensions and in all directions, and the detergent decomposes the oil and residue on the surface of the tableware. In addition, the hot water soaks and expands the food residue, so that the oil and residue are quickly decomposed and fall off, and finally achieves the cleaning effect. Due to the limitations of the working principle of the dishwasher, 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, the dishwasher-specific detergent 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 heavy oil from hot pots.

[0031] 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, and the ester molecular structure is similar to the structure of grease and wax. According to the principle of similar compatibility, it has a strong dissolving and removing ability for grease, mineral oil and paraffin wax. It has a very reasonable double bond structure and has good dispersing and removing power for lipids; surfactant C is similar to the structure of oleic acid and fatty acids in 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 grease from the matrix.

[0032] According to some embodiments of the present invention, the weight percentage of the surfactant in the cleaning agent is 5-30%, more preferably 5-12%.

[0033] 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.

[0034] According to some embodiments of the present invention, the surfactant C is one or more of triethylamine oleate, ethylenediamine oleate, and triethanolamine oleate soap.

[0035] 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 2-8 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;

[0036] The surfactant B is long-chain carboxylate polyoxyethylene-18;

[0037] The surfactant C is ethylenediamine oleate.

[0038] According to some embodiments of the present invention, the weight percentage of the deodorizing agent in the cleaning agent is 0.1-10%, and the deodorizing agent is at least one of a chemical deodorizing agent, a biological deodorizing agent, and a plant deodorizing agent.

[0039] Among them, the chemical deodorant can be one or more of castor oil alcohol zinc, soybean ethyl sulfate morpholine, chlorine dioxide, photocatalyst, methacrylate fatty alcohol, and wood vinegar. The odor components and the deodorant are converted into odor-free substances through chemical reactions such as oxidation, reduction, addition, and condensation, and the odor components are completely decomposed, and the odor is removed quickly and effectively.

[0040] Biological deodorizers are mainly microbial enzymes. They use the metabolism of microbial flora or their metabolites to effectively degrade common odor factors such as volatile fatty acids and hydrogen sulfide. They are safe and non-toxic to humans and animals, non-irritating, biodegradable, and have no secondary pollution.

[0041] The plant-based deodorant can be one or more of tea extract, yucca extract, phytoncides, wormwood extract, lemon essential oil, chamomile essential oil, etc. The effective ingredients are extracted from plant roots, stems, leaves, flowers, fruits and other parts.

[0042] According to some embodiments of the present invention, the deodorizing aid comprises a biological deodorizing agent and a yucca extract in a mass ratio of 1:5-5:1. Among them, the biological deodorizing agent is preferably a probiotic flora or its metabolites, which can effectively degrade common odor factors such as volatile fatty acids and hydrogen sulfide; the effective ingredients of yucca extract (such as saponin) can strongly adsorb odor molecules such as ammonia. The saponin aglycones in the yucca extract are lipophilic, and the sugar chains have strong hydrophilicity, making it a natural surfactant. The combination of the biological deodorizing agent and the yucca extract can enhance the degreasing effect, can naturally decompose deep cleansing dirt, and effectively remove odors.

[0043] Furthermore, in order to better remove odor, the cleaning agent also contains a flavor with a deodorizing function. The flavor component contains a cyclohexyl ethyl carboxylate composition, which contains enantiomeric compounds of (1R)-1-cyclohexyl ethyl butyrate and (1S)-1-cyclohexyl ethyl acetate. This unique flavor ingredient has a certain fragrance itself, which can mask a part of the odor. At the same time, it can bind to the same receptors in the nose as the odor molecules, thereby eliminating the feeling of odor by making the odor molecules unable to reach these receptors.

[0044] 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.

[0045] Alkaline additives have the ability to saponify grease. The amount of alkaline additives used in the present invention is more than the conventional amount. The advantage of this is that the addition of a large amount of alkaline substances can simultaneously achieve the synergistic effects of saponification reaction, emulsification and solubilization, neutralization reaction, and alkali swelling. Alkaline substances are prone to saponification reactions to generate soaps and glycerol that are soluble in water to achieve the purpose of removal. At the same time, soap is also an anionic surfactant that can play a role in emulsifying and solubilizing grease. The polymerized grease products after oxidative polymerization of grease in the air carry acidic groups such as peroxides and hydroxyls, which are more likely to undergo neutralization reactions with alkaline substances, thereby greatly enhancing their hydrophilicity. Alkali can also produce a swelling effect on the resin-like substance formed by unsaturated grease polymers, which reduces the binding force between grease and solid surfaces and the density of dirt.

[0046] 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.

[0047] Specifically, it can be one or more of sodium percarbonate, calcium peroxide, sodium perborate, sodium hypochlorite, TAED, and Mn (II / IV) compounds.

[0048] 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.

[0049] 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.

[0050] In the prior art, chelating agents can chelate calcium ions and magnesium ions to resist scale deposition. The present invention uses amino acid derivative chelating agents, such as GLDA and MGDA, which are easily biodegradable. According to the OECD 301D test, the biodegradation rate in 28 days exceeds 80%. According to the latest GHS classification, these two green chelating agents do not have the hazard identification (explosion symbol on the chest) of EDTA and NTA. Among them, GLDA uses monosodium glutamate as raw material, and 48% of its weight ratio comes from natural plant products. It is the only carboxylic acid-based chelating agent that has half of its carbon atoms coming from natural carbon atoms. Its chelating performance is also relatively strong. Like EDTA and NTA, it is a strong chelating agent that can effectively remove the "calcium bonds" that bind grease and stains.

[0051] 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.

[0052] 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, and colored particles.

[0053] Among them, the defoaming agent is preferably a polysiloxane defoaming agent, including one or more of dimethylsiloxane, phenylsiloxane, and amino-terminated siloxane.

[0054] 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.

[0055] According to some embodiments of the present invention, the cleaning agent comprises the following components by weight percentage:

[0056] Surfactant 5-30%

[0057] Deodorizing agent 0.1-10%

[0058] Flavor 0.1-5%

[0059] Alkaline additive 20-50%

[0063] Enzyme preparation 0.02-30%

[0064] Polysiloxane defoamer 0.02-5%

[0065] Other additives 0.1-30%.
