Description

Technology Field

[0001] The present invention relates to a detergent composition for preventing color deformation and fading of fibers, and more specifically, to an improved detergent composition for preventing color deformation and fading of fibers that can prevent color deformation and fading of fibers caused by metal ion reactions and oxidation during the washing process, as well as everyday exposure to light and heat such as sunlight or dryer heat. Background Technology

[0002] Generally, detergent used for laundry is a substance added when washing fabrics to help clean them.

[0003] These laundry detergents are mainly used in solid form, such as powder or granules, and recently, liquid detergents are also being sold.

[0004] Furthermore, commercially available laundry detergents are primarily developed and used with an emphasis on foaming ability, cleaning power, ease of use, and volume control.

[0005] These general detergents contain high concentrations of surfactants and alkaline compositions to ensure cleaning power, but this causes damage to skin proteins and lipid layers, and weakens the skin barrier.

[0006] In particular, while general detergents secure cleaning power through a combination of surfactants and cleaning aids, problems arise during the washing process where reactions with metal ions, oxidation, and micro-damage to the fiber surface cause the dyed fibers to gradually fade or color transfer to occur.

[0007] In addition, since color vibrancy may decrease and color changes may occur during repeated washing, a detergent composition that simultaneously inhibits metal ions and alleviates washing stress is required. Prior art literature

[0008] Korean Published Patent No. 10-2023-0114137 (Aug. 1, 2023) Title: Eco-friendly Laundry Detergent The problem to be solved

[0009] The present invention was created to solve the various problems of the prior art as described above, and its main purpose is to provide an improved detergent composition that prevents color deformation and fading of fibers, which can prevent color deformation and fading of fibers caused by metal ion reactions and oxidation during the washing process, as well as everyday exposure to light and heat such as sunlight or dryer heat. means of solving the problem

[0010] The present invention provides, as a means to achieve the above-mentioned objective, a detergent composition for preventing color deformation and discoloration of fibers, characterized by comprising 30% by weight of alkyl glucoside, 5% by weight of tetrasodium iminodisuccinate, 20% by weight of sodium cocoyl isethionate, 5% by weight of methylglycinediacetic acid, 10% by weight of sodium carbonate peroxy hydrate, 10% by weight of tetrasodium glutamate diacetate, 7% by weight of sodium hydrogen carbonate, 3% by weight of sodium carboxymethyl inulin, and 10% by weight of sodium sesquicarbonate dihydrate. Effects of the invention

[0011] According to the present invention, an improved effect can be obtained to prevent color deformation and fading of fibers caused by metal ion reactions and oxidation during the washing process, as well as everyday exposure to light and heat such as sunlight or dryer heat. Specific details for implementing the invention

[0012] Hereinafter, preferred embodiments according to the present invention will be described in more detail.

[0013] Since embodiments according to the concept of the present invention may be subject to various modifications and may take various forms, it should be understood that they include all modifications, equivalents, and substitutions that fall within the spirit and technical scope of the present invention.

[0014] The detergent composition for preventing color deformation and fading of fibers according to the present invention is characterized by including a metal ion inhibitory component and a fiber protection auxiliary component to reduce factors causing color change due to metal reactions and oxidation during washing, and to minimize damage to the fiber surface to maintain the original color.

[0015] In particular, it is characterized by a non-ionic surfactant-based composition that reduces residue remaining on fibers, prevents damage to the dye layer, and maintains vibrancy after washing.

[0016] More specifically, the detergent composition according to the present invention comprises 30% by weight of alkyl glucoside, 5% by weight of tetrasodium iminodisuccinate, 20% by weight of sodium cocoyl isethionate, 5% by weight of methylglycinediacetic acid, 10% by weight of sodium carbonate peroxy hydrate, 10% by weight of tetrasodium glutamate diacetate, 7% by weight of sodium hydrogen carbonate, 3% by weight of sodium carboxymethyl inulin, and 10% by weight of sodium sesquicarbonate dihydrate.

[0017] At this time, alkyl glucoside is an eco-friendly, low-irritation, non-ionic surfactant that does not carry an electric charge and therefore does not denature skin proteins. Furthermore, it has the advantage of being safe to use because it causes very low skin irritation.

[0018] In particular, sodium iminodisuccinate (Tetrasodium Iminodisuccinate) is non-toxic to the human body and has the characteristic of preventing surfactants from clumping together by strongly capturing calcium (Ca) and magnesium (Mg) ions in water, and also has good blocking ability not only of metal ions but also of iron (Fe) and copper (Cu) ions, which prevents white clothes from turning yellow.

[0019] Furthermore, Sodium Cocoyl Isethionate is a detergent that functions as a natural plant-based surfactant derived from coconut. It is obtained as a white powder through the combination of fatty acids extracted from coconut oil and isethionic acid; it improves cleaning power by reducing the interfacial tension of fabrics, allowing oil, water, and dust to mix together.

[0020] In addition, methylglycinediacetic acid not only has high thermal and chemical stability that does not degrade performance even in high temperatures or strong alkaline environments, but also very effectively inhibits the deposition of limescale during washing and contributes to clean rinsing without residue.

[0021] In addition, sodium carbonate peroxyhydrate is Na2CO4·H2O formed by mixing sodium carbonate and hydrogen peroxide, and functions as a 100% oxygen-based disinfectant and bleaching agent that contains no fluorescent whitening agents or surfactants. In particular, because it is in the form where hydrogen peroxide is attached to sodium carbonate, it dissolves easily when it comes into contact with water, increasing its activity and enhancing its disinfection and bleaching functions.

[0022] In addition, Tetrasodium Glutamate Diacetate is an ingredient based on the plant-based amino acid 'L-glutamate', which has excellent mineral (calcium, magnesium) blocking ability and, in particular, has a synergistic effect that amplifies the cleaning power of other ingredients in the detergent.

[0023] In addition, sodium hydrogen carbonate induces bending in the fibers through the foaming force resulting from expansion, thereby enhancing the cleaning effect.

[0024] In addition, Sodium Carboxymethyl Inulin is made from 100% plant-based materials and has the advantage of simultaneously performing the function of trapping metal ions and the 're-contamination prevention' function of preventing contaminants from sticking to the fibers again.

[0025] In addition, sodium sesquicarbonate dihydrate is a substance corresponding to CAS No. 6106-20-3, and is a natural ingredient that has excellent cleaning power against oil, sweat, sebum, blood, and protein stains while reducing skin irritation.

[0026] Meanwhile, in the present invention, 10 parts by weight of sodium glucoheptonate, 10 parts by weight of sodium gluconate, 10 parts by weight of propanediol, 5 parts by weight of polyaspartic acid, 8 parts by weight of alkyl polyglucoside (APG), 7.5 parts by weight of polyquaternium, and 5.5 parts by weight of benzoguanamine may be further added to 100 parts by weight of the detergent composition.

[0027] In this case, sodium glucoheptonate is an organic compound derived from natural sugars; its ability to bind metal ions is maximized in alkaline rather than acidic environments, and it contributes to preventing discoloration by stably binding transition metals that other chelating agents tend to miss.

[0028] In addition, sodium gluconate is a natural ingredient derived from corn, is highly biodegradable and harmless to the human body, and contributes significantly to suppressing the generation of detergent residue.

[0029] In addition, propanediol is a natural solvent obtained from corn fermentation that helps moisturize the skin, facilitates the transparent dissolution of detergent ingredients, and contributes to suppressing detergent residue.

[0030] In addition, polyaspartic acid is a biodegradable polymer made by polymerizing the amino acid 'aspartic acid'. Unlike general low-molecular-weight chelating agents, it simultaneously performs the role of a 'dispersing agent'. It not only captures metal ions but also has the advantage of excellent residue suppression ability by pushing away already formed fine residue particles so that they do not clump together and float in water.

[0031] In particular, alkyl polyglucosides (APGs) are sugar-based surfactants extracted from coconut or corn, which are highly biodegradable, cause little skin irritation, and have excellent oil removal capabilities.

[0032] In addition, Polyquaternium is a cationic polymer that electrostatically binds to the skin and fiber surfaces to form a smooth protective film, providing a conditioning effect that remains on the skin even after cleansing to prevent dryness.

[0033] Also, Benzoguanamine is a substance corresponding to CAS number 91-76-9 that inhibits shrinkage deformation and inhibits the generation of static electricity.

[0034] Furthermore, in the present invention, 10 parts by weight of sodium phytate, 5.5 parts by weight of sodium citrate, 10 parts by weight of coco-glucoside, 10 parts by weight of HPMC (hydroxypropylmethylcellulose), 5 parts by weight of tocopheryl acetate, and 5 parts by weight of glutamate diacetate (GLDA) may be further added to 100 parts by weight of the detergent composition.

[0035] In this case, sodium phytate is a natural plant-based chelating agent extracted from rice bran or seeds and is one of the powerful natural ion sequestering agents. It has 12 phosphate groups, allowing it to bind with a large amount of metal ions simultaneously. It also has a powerful antioxidant effect, which prevents the rancidity of oil components in the detergent and helps maintain the soft texture of the fabric after washing.

[0036] In addition, sodium citrate lowers the pH and acts as a buffer to prevent rapid changes in pH.

[0037] In addition, Coco-Glucoside is considered one of the mildest cleaning ingredients and contributes effectively to breaking down stubborn dirt.

[0038] In particular, HPMC (hydroxypropylmethylcellulose) has excellent moisturizing and film-forming functions, which help maintain moisture on the skin and reduce direct contact with external chemicals.

[0039] In addition, tocopheryl acetate prevents oxidation of the detergent composition and induces stabilization.

[0040] In addition, glutamate diacetate (GLDA) is a natural chelating agent based on plant-based amino acids, which has the effect of preventing limescale and enhancing cleaning power.

[0041] On the other hand, in the present invention, the alkyl glucoside is preferably lauryl glucoside, and rather than using it alone, it is particularly preferred to use it in the form of a mixture in which 5.5 parts by weight of arginine, 4.5 parts by weight of citric acid, 5 parts by weight of phytic acid, 10 parts by weight of panthenol, 15 parts by weight of glycolipids, and 10 parts by weight of aloe vera extract are further added based on 100 parts by weight of the alkyl glucoside.

[0042] Here, arginine is a basic amino acid that gently raises the pH to between 6.5 and 8.0, and is highly biodegradable and eco-friendly, in addition to its skin moisturizing effect.

[0043] In addition, citric acid is essential for neutralizing strong alkaline cleaning ingredients to precisely adjust the pH to the target range of 6.5 to 8.0, and it also performs a buffering function to fix the pH of the detergent so that it does not change rapidly due to external factors.

[0044] Furthermore, phytic acid is a natural organic acid extracted from rice bran or seeds. It serves to lower pH while simultaneously acting as a powerful natural chelator (metal ion blocking agent), which not only provides excellent residue inhibition but also combines with minerals in water to prevent laundry discoloration and enhance cleaning power.

[0045] In particular, Panthenol strengthens the skin's protective barrier along with its fabric softening effect, preventing roughness during hand washing. In other words, as a precursor to Vitamin B5 (pantothenic acid), it is excellent for moisturizing the skin and strengthening the skin barrier.

[0046] In addition, glycolipids are natural surfactants extracted through microbial fermentation. They form a smooth layer with small particles that directly reduces skin friction. Therefore, they contribute to preventing skin troubles by forming a lubricating layer on the skin during hand washing, thereby suppressing friction with the skin.

[0047] In addition, the polysaccharide components of Aloe Vera extract form a thin moisture film on the skin, contributing to soothing the skin from detergent irritation and alleviating friction.

[0048] On the other hand, in the present invention, sodium cocoyl isethionate is not used alone, but is particularly preferred to be used in the form of a mixture in which 6.5 parts by weight of gluconolactone, 4.5 parts by weight of galactaric acid, 5.5 parts by weight of succinic acid, 10 parts by weight of alcohol ethoxylates, 10 parts by weight of apple wash (sodium cocoyl apple amino acids), 10 parts by weight of glyceryl linoleate, and 10 parts by weight of capric triglyceride are added based on 100 parts by weight of sodium cocoyl isethionate.

[0049] At this time, gluconolactone is a lactone derived from corn, etc., which gradually changes into gluconic acid upon contact with water. It has an excellent ability to gradually lower and maintain the pH at a constant level, contributing to the precise setting of pH 6.5 to 8.0 during detergent manufacturing.

[0050] Also, galactaric acid is a natural acid component derived from pectin in fruits (apples, tangerines, etc.), exhibits a more precise binding affinity to metal ions, and has antioxidant functions that prevent the deterioration of plant oil components in detergents and also assist in skin soothing effects.

[0051] In addition, succinic acid is a natural organic acid found in shellfish and amber. It possesses excellent pH-regulating capabilities and antibacterial and antioxidant effects, which prevent the proliferation of microorganisms in detergents. Furthermore, due to its high compatibility with other ingredients, it contributes to increasing the transparency of the detergent and reducing the occurrence of precipitates (residues).

[0052] In particular, fatty alcohol ethoxylates are nonionic surfactants that have excellent solubility even in cold water and contribute to preventing detergent from remaining on fibers by rapidly dispersing oil stains into water and minimizing the amount of residue.

[0053] In addition, Apple Wash (Sodium Cocoyl Apple Amino Acids) is based on amino acids extracted from apple juice and leaves a lubricating film with a soft texture on the skin even after washing, preventing skin trouble caused by reduced friction.

[0054] In addition, Glyceryl Linoleate is a component derived from plant fatty acids that is similar to the skin's lipid structure and protects the skin by immediately replenishing the oil lost during the cleansing process.

[0055] In addition, Caprylic Triglyceride is a refined liquid oil component extracted from plant-derived fatty acids, such as coconut oil or canola oil. It is characterized by powerful skin lubrication and the formation of a protective barrier, preventing skin irritation caused by reduced friction.

[0056] The following describes the embodiments.

[0057] The following examples were made to evaluate a detergent composition that prevents color deformation and discoloration of fibers according to the present invention.

[0060] [Example 2]

[0061] A second sample of a detergent composition was prepared by further adding 10 parts by weight of sodium glucoheptonate, 10 parts by weight of sodium gluconate, 10 parts by weight of propanediol, 5 parts by weight of polyaspartic acid, 8 parts by weight of alkyl polyglucoside (APG), 7.5 parts by weight of polyquaternium, and 5.5 parts by weight of benzoguanamine to the above Example 1.

[0062] [Example 3]

[0063] A third sample of a detergent composition was prepared by further adding 10 parts by weight of sodium phytate, 5.5 parts by weight of sodium citrate, 10 parts by weight of coco-glucoside, 10 parts by weight of HPMC (hydroxypropylmethylcellulose), 5 parts by weight of tocopheryl acetate, and 5 parts by weight of glutamate diacetate (GLDA) to the above Example 2.

[0064] As a result of evaluating the cleaning power of the first, second, and third samples, the BULK DENSITY, particle size, appearance and scent, effective oxygen content, moisture content, and pH (1% Water Soln.) all significantly exceeded the standard product, and all test evaluation criteria were passed.

[0065] In addition, a sensory evaluation was conducted for 6 months on 10 women in their 30s and 10 women in their 40s regarding roughness after hand washing of samples 1, 2, and 3, and the results showed that no skin barrier issues, skin problems, or moisture loss occurred.

[0066] Furthermore, no discoloration due to oxidation occurred after washing. In addition, no residue was produced.
