Description

Technical Field

[0001] This invention belongs to the field of washing and care products. Specifically, it relates to a washing and care composition, preparation method and application. More specifically, it relates to a washing and care composition and preparation method for use with washing equipment with automatic dispensing function. Background Technology

[0002] With the improvement of living standards, modern families have widely adopted household washing appliances such as washing machines and dishwashers to solve the inconvenience of traditional hand washing. Furthermore, with the rapid development of technology, intelligent automatic dispensing systems have emerged. Compared to traditional manual dispensing washing equipment, intelligent automatic dispensing washing appliances, with their high efficiency, intelligence, and environmental friendliness, can save time and resources in household washing and provide users with better washing results.

[0003] As living standards improve, people's demands for toiletries have become more diversified. In addition to regular liquid detergents, fabric softeners, bleach, disinfectants, cleaning aids, brighteners, conditioners, care solutions, and tub cleaners have also emerged.

[0004] However, most home appliance manufacturers and laundry product manufacturers are still operating independently. The integration between household washing appliances with automatic dispensing functions and existing laundry products is not yet sufficient, which leads to a series of mismatch problems in actual use by users and causes them inconvenience.

[0005] Specifically, the problems that arise when combining existing automatic dispensing household washing appliances with commercially available laundry care products include:

[0006] 1. The shampoo and body care products are not being dispensed or the dispensing accuracy is low; the reason is that the two are not compatible, and the viscosity of the shampoo and body care products is not within the range required by the automatic dispensing equipment.

[0007] 2. The washing and care product is not recognized by the electrical appliance, and it keeps alarming for low liquid or there is no liquid but no alarm is triggered; the reason is that the recognition signal is asymmetrical or the washing and care product does not have the recognition signal required by the sensor.

[0008] 3. Excessive foam, overflowing foam, or almost no foam during washing, incomplete rinsing, or foam residue; the cause is an issue with the dosage, or the foam content of the washing and care product itself is not suitable for automatic dispensing by the appliance, resulting in a mismatch between the two.

[0009] 4. If washing and care products are stored in a washing appliance for a period of time and problems such as layering, skin formation, gelling, or clogging occur, it is because their heat resistance and stability are poor, leading to skin formation and gelling.

[0010] 5. Peeling, cracking, or corrosion of parts such as the panel on some parts of the washing appliance; the reason is that a certain ingredient or some ingredients in the washing and care products corrode the panel.

[0011] Therefore, it would be of great significance to provide a laundry care product that can be used with automatic dispensing washing equipment to solve a series of problems caused by the incompatibility between household appliances and laundry care products.

[0012] In view of this, the present invention is proposed. Summary of the Invention

[0013] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a washing and care composition, preparation method and application. The present invention controls the combination and ratio of each component so that the viscosity of the washing and care composition is suitable for the precise automatic dispensing of washing equipment, the conductivity range can be accurately identified by the conductivity sensor, the foam is appropriate and there is no foam residue after rinsing, the stability is good and it does not corrode the washing equipment, and it is suitable for use with washing equipment with automatic dispensing function.

[0014] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0015] This invention provides a shampoo and conditioner composition comprising:

[0016]

[0017] The second nonionic surfactant includes branched oleoethylene ethers and amine ethers.

[0018] Furthermore, the first nonionic surfactant is selected from at least one of fatty alcohol polyoxyethylene ether, alkylphenol polyoxyethylene ether, fatty acid polyoxyethylene ester, polyoxyethylene alkylamine, polyoxyethylene alkylamide, and polyethers.

[0019] Furthermore, the anionic surfactant includes sulfonates and sulfates;

[0020] Preferably, the sulfonate includes alkylbenzene sulfonate and olefin sulfonate;

[0021] Preferably, the sulfate salt includes fatty alcohol polyoxyethylene ether sulfate salt.

[0022] Furthermore, the low-foaming surfactants include EO-PO block polyethers and polyether-modified organosilicones.

[0023] Furthermore, the solvent is selected from one or a combination of two or more of ethanol, propylene glycol, glycerol, polyethylene glycol, and sorbitol.

[0024] Furthermore, it includes adjuvants, which include one or a combination of two or more of enzyme preparations, chelating agents, dispersants, preservatives, flavorings, and pigments;

[0025] Preferably, the enzyme preparation is selected from one or a combination of two or more of protease, lipase, cellulase, and pectinase.

[0026] Preferably, the chelating agent is selected from one or a combination of two or more of sodium citrate, ethylenediaminetetraacetic acid, tetrasodium glutamate diacetate, methylglycine diacetate, and hydroxyethylidene diphosphate;

[0027] Preferably, the dispersant is selected from one or two of polyethyleneimine ethoxylate and hydrophobic modified carboxylic acid copolymer.

[0028] Furthermore, the viscosity range of the washing and care composition is 50–2500 mPa·s.

[0029] Furthermore, the electrical conductivity of the shampoo and conditioner composition ranges from 1500 to 50000 uS / cm.

[0030] The present invention also provides a method for preparing the shampoo and conditioner composition as described above, comprising:

[0031] (1) Weigh a measured amount of water, add an anionic surfactant, and stir until homogeneous;

[0032] (2) Add the second nonionic surfactant in the specified amount while stirring, and stir until uniform;

[0033] (3) Add the solvent according to the specified amount while stirring, and stir until uniform;

[0034] (4) Add the first nonionic surfactant according to the specified amount while stirring, and stir until uniform;

[0035] (5) Add the additives in the correct amount while stirring, and stir until uniform to obtain the washing and care composition.

[0036] The present invention also provides the application of the washing and care composition described above in the washing and care process of items in a washing equipment with an automatic dispensing function;

[0037] Preferably, washing equipment with automatic dispensing function includes washing machines, dishwashers, and washer-dryer combos.

[0038] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0039] 1. The washing and care composition of the present invention includes anionic surfactant, a first nonionic surfactant, branched oil ethylene ether and amine ether, low foaming surfactant and solvent. These five types of substances can work synergistically with each other, and the mass ratio of each component can be controlled within a certain range, so that the viscosity and conductivity of the washing and care composition are suitable for matching the washing equipment, and the composition has good stability, low foam and no residue.

[0040] 2. The viscosity of the washing and care composition of the present invention is tested at -5 to 50°C. The viscosity range is between 50 and 2500 mPa·s. The viscosity is within the range required by the automatic dispensing washing equipment. The washing equipment can achieve automatic and accurate dispensing with an accuracy of less than 10% dispensing error.

[0041] 3. Conventional washing equipment uses conductivity as an identification signal (conductivity sensor) when detecting detergents and other products. Conductivity is measured at temperatures ranging from -5°C to 50°C. The conductivity range of the washing and care composition of this invention is 1500–50000 uS / cm. Therefore, the washing equipment can accurately identify the presence or absence of washing and care products and accurately determine the liquid level of the products.

[0042] 4. The washing and care composition of the present invention generates a low to medium amount of foam during the washing process. For example, at a temperature of 30°C, the amount of foam in the main wash of a conventional washing program is 1 / 3 to 2 / 3 of the full tub. After rinsing, there is no foam residue, which can effectively clean the product.

[0043] 5. The washing and care composition of the present invention has good stability. It does not form a skin, gel, solidify, or clog washing equipment when left open at a high temperature of 45°C for 3 days.

[0044] 6. Currently, the surface material for household washing equipment is mainly ABS plastic, which has good thermoplasticity and aesthetics. However, the use of ABS has certain drawbacks when combined with daily chemical products. This invention involves applying a washing and care composition to an ABS panel and placing it at 45°C for 48 hours to observe whether it dissolves or corrodes. The results show that the washing and care composition of this invention does not corrode the sprayed coating, painted surface, or panel.

[0045] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0049] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0051] Unless the context otherwise requires, the terms “comprising” and “including” in the specification and claims shall be understood as open-ended and inclusive, meaning “including, but not limited to”.

[0052] The terms "implementation," "one embodiment," "another embodiment," or "certain embodiments" used in this specification refer to specific features, structures, or characteristics described in relation to the described implementation that are included in at least one embodiment. Therefore, "implementation," "one embodiment," "another embodiment," or "certain embodiments" do not necessarily all refer to the same implementation. Furthermore, specific features, structures, or characteristics can be combined in any way within one or more embodiments. Each feature disclosed in this specification can be replaced by any alternative feature that provides the same, equivalent, or similar purpose. Therefore, unless otherwise specified, the disclosed features are merely general examples of equivalent or similar features.

[0053] The shampoo and conditioner composition of the present invention comprises:

[0054]

[0055] The second nonionic surfactant includes branched oleoethylene ethers and amine ethers.

[0056] In a further embodiment, the first nonionic surfactant is selected from at least one of fatty alcohol polyoxyethylene ether, alkylphenol polyoxyethylene ether, fatty acid polyoxyethylene ester, polyoxyethylene alkylamine, polyoxyethylene alkylamide, and polyethers.

[0057] In the washing and care composition of the present invention, through the synergistic interaction of five types of substances—anionic surfactant, first nonionic surfactant, branched oil ethylene ether and amine ether, low-foaming surfactant and solvent—and by controlling the mass ratio of each component within the above-mentioned range, the viscosity of the washing and care composition is suitable for precise automatic dispensing by washing equipment, the conductivity range can be accurately identified by the conductivity sensor of the washing equipment, the foam is appropriate and there is no foam residue after rinsing, the composition has good stability and does not corrode the washing equipment, and therefore it is more suitable for use with washing equipment with automatic dispensing function.

[0058] The washing and care composition of the present invention can be a laundry detergent, a dishwashing detergent, or a clothing or dishwashing care agent; it is not limited to washing, stain removal, or care.

[0059] In the washing and care composition of the present invention, the combination of anionic surfactant, a first nonionic surfactant, a low-foaming surfactant, and branched oleoethylene ether and amine ether not only has suitable viscosity and conductivity, but also does not skin, gel, or solidify, will not clog or corrode washing equipment, produces a low to medium amount of foam, and is easy to rinse without residue. When the mass ratio of the substances in the above washing and care composition is not within the above range, the effect is relatively poor.

[0060] Branched oil vinyl ethers and amine ethers It is a polymer of vinyl ethers and amine ethers with polymerizable oil and fat monomers. The properties of oil and fat polymers can be imparted to vinyl ethers and amine ethers, and in particular, their block copolymers can be used as high molecular weight surfactants.

[0061] Branched oleoethylene ethers and amine ethers are novel nonionic surfactants derived from oils and fats. They exhibit good biodegradability, excellent solubilizing, emulsifying, dispersing, and detergency properties, are mild, have low irritation, do not easily form gels, and possess excellent antifreeze properties. The product does not easily discolor. It can be used in combination with various nonionic, anionic, and amphoteric surfactants.

[0062] Optionally, the branched oil-based ethylene ethers and amine ethers are fatty amine polyoxyethylene ethers, with branched fatty amine polyoxyethylene ethers being preferred.

[0063] Preferably, the branched oleoethylene ethers and amine ethers are products with the trade name Ucorse XC90.

[0064] Anionic surfactants Any substance suitable for use in the washing and care field can be used. For example, based on the structure of its hydrophilic group, it can include one or a mixture of two or more of the following: sulfonates, sulfates, carboxylates, and phosphates.

[0065] Alternatively, in the washing and care composition of the present invention, the anionic surfactant is mainly selected from one or more of sulfonates and sulfates.

[0066] Optionally, the sulfonate includes alkylbenzene sulfonates and olefin sulfonates; for example, sulfonates include sodium alkylbenzene sulfonate (e.g., sodium dodecylbenzene sulfonate) or α-olefin sulfonates (e.g., C11-C17 AOS).

[0067] Sulfate salts include: fatty alcohol polyoxyethylene ether sulfates (such as AES).

[0068] Optional options: Anionic surfactants can be selected from one or a mixture of two or more of the following products: LAS (sodium linear alkylbenzene sulfonate), HLAS, AOS (α-olefin sulfonate), and AES.

[0069] First nonionic surfactant Any nonionic surfactant that can be used in the field of washing and care can be used.

[0070] First-order nonionic surfactants possess high surface activity, excellent solubilizing, detergency, antistatic, and calcium soap dispersing properties, low irritation, and superior wetting and detergency functions. Based on the structure of their hydrophilic groups, first-order nonionic surfactants can be classified into polyoxyethylene type, polyol type, alkanolamide type, polyether type, and amine oxide type, among others.

[0071] In some embodiments, the first nonionic surfactant used in this invention is mainly one or a combination of two or more of fatty alcohol polyoxyethylene ether, alkylphenol polyoxyethylene ether, fatty acid polyoxyethylene ester, polyoxyethylene alkylamine, polyoxyethylene alkylamide (R-CONH(C2H4O)nH) and polyethers.

[0072] Alternative options: The general formula for fatty alcohol polyoxyethylene ethers is RO(CH2CH2O)nH, where n is the degree of polymerization. For example, it may include one or a mixture of AEO3, AEO5, AEO7, and AEO9.

[0073] Fatty acid polyoxyethylene esters may include emulsifier A103 and / or emulsifier A105.

[0074] Polyethers may include polyethylene glycol ethers, polyoctyl alcohol ethers, and polyoxyethylene polyoxypropylene block polyethers (such as L61, L64, F68, F108, etc.).

[0075] Low-foaming surfactants You can use any low-foaming surfactant that is suitable for the washing and care industry.

[0076] Low-foaming surfactants possess strong dispersibility and dispersion retention, can regulate the balance between lipophilic and hydrophilic substances, and exhibit excellent emulsifying, solubilizing, and suspending properties. They are important components of cleaning agents and come in a wide variety. Low-foaming surfactants mainly include EO / PO block polyethers, isooctanol phosphate derivatives, ethoxylated fatty acid methyl ester derivatives, and polyether-modified organosilicon surfactants.

[0077] In some embodiments, the low-foaming surfactant used in this invention includes one or a combination of two or more of EO-PO block polyethers and polyether-modified organosilicones.

[0078] In some embodiments, polyether-modified silicones include KSG-210 from Guangzhou Huazhiwang Chemical Co., Ltd., VOK-WET 3060 from Guangzhou Siteyuan Chemical Co., Ltd., and Solvay AEROSOL OT75, etc.

[0079] solvent You can use any solvent that is suitable for the washing and care industry.

[0080] The solvents are mainly alcohols, including polyols and lower alcohols. Examples of polyols include propylene glycol, glycerol, polyethylene glycol, ethylene glycol, and sorbitol, while lower alcohols include ethanol, n-butanol, and isopropanol.

[0081] In some embodiments, the solvents used in this invention include one or a combination of two or more of ethanol, propylene glycol, glycerol, polyethylene glycol, and sorbitol.

[0082] In some embodiments, the washing and care composition also includes additives.

[0083] Different additives can be added to the cleaning agent depending on the actual needs.

[0084] Additives include one or more of the following: enzyme preparations, chelating agents, dispersants, pH adjusters, preservatives, flavorings, and colorings.

[0085] Different additives can be added to the cleaning agent according to actual needs. However, the use of additives has no substantial impact on the viscosity, conductivity, stability, low to medium foaming volume, and non-corrosive properties of the cleaning and care composition of the present invention. Any commonly used additives in the washing field in the prior art can be selected.

[0086] For example, enzyme preparations include single enzymes such as protease, lipase, cellulase, and pectinase, as well as complex enzymes containing multiple single enzymes.

[0087] Chelating agents include one or a mixture of two or more of sodium citrate, EDTA, GLDA, MGDA, and HEDP.

[0088] The dispersant includes one or a mixture of polyethyleneimine ethoxylate (HP20), hydrophobic modified carboxylic acid copolymer (747).

[0089] pH adjusters include alkalis or citric acid.

[0090] Fragrance agents include flavorings, etc.

[0091] In some embodiments, the viscosity range of the washing and care composition of the present invention is 50 to 2500 mPa·s.

[0092] Generally, the viscosity specifications required by the automatic dispensing devices of washing machines and dishwashers are within 5000 mPa·s, with an accuracy of 20%. If the viscosity exceeds 5000, it is too viscous, has very low fluidity, and results in a large error.

[0093] The viscosity range of the washing and care composition of the present invention can be controlled within 50 to 2500 mPa·s, exhibiting good fluidity and enabling automatic and precise dispensing with an accuracy error controlled within 10%. The viscosity range of the present invention was tested between -5 and 50°C; generally, viscosity increases at low temperatures and decreases at high temperatures.

[0094] In some embodiments, the electrical conductivity of the washing and care composition ranges from 1500 to 50000 μS / cm.

[0095] Conventional washing equipment uses conductivity as an identification signal (conductivity sensor) to detect detergents and other products. The conductivity range of the washing and care composition of this invention is 1500–50000 uS / cm, allowing for precise identification of the presence or absence of washing and care products, and providing higher sensitivity in the detection signal. The conductivity measured by this invention between -5 and 50°C shows that at low temperatures, especially before 5°C, the conductivity is low and does not change significantly. After 5°C, the conductivity increases sharply with increasing temperature.

[0096] The washing and care composition of the present invention generates a low to medium amount of foam during the washing process. For example, at a temperature of 30°C, the amount of foam in the main wash of a conventional washing program is 1 / 3 to 2 / 3 of the full tub. After rinsing, there is no foam residue, which can effectively clean the product.

[0097] The washing and care composition of the present invention has good stability. It does not form a skin, gel, solidify, or clog washing equipment when left open at a high temperature of 45°C for 3 days.

[0098] The washing and care composition of the present invention does not contain any components that would corrode ABS panels, and is non-corrosive to spraying, painting, and panels.

[0099] Currently, the surface material for household washing equipment is mainly ABS plastic, which has good thermoplasticity and aesthetics. However, the use of ABS has certain drawbacks when combined with daily chemical products. This invention involves applying a washing and care composition to an ABS panel and placing it at 45°C for 48 hours to observe whether it dissolves or corrodes. The results showed no corrosion.

[0100] In the examples, the branched oleoyl ethylene ether and amine ether (XC90), trade name Ucorse XC90, is manufactured by Guangdong Qinxiang New Materials Co., Ltd.

[0101] In the examples, sodium salt of fatty alcohol polyoxyethylene ether sulfate (AES) is Hunan Lichen AES.

[0102] In this embodiment, AEROSOL OT75 is Solvay AEROSOL OT75.

[0103] In the examples, KSG-210 is a product of Guangzhou Huazhiwang Chemical Co., Ltd.

[0104] In the embodiment, LF221 is a BASF product.
