Description

Technical Field

[0001] The invention belongs to the technical field of detergents, and in particular relates to a detergent composition and its use. Background Art

[0002] At present, various commercially available laundry detergents need to be rubbed or kneaded repeatedly when washing clothes, especially for stubborn stains (such as blood stains), which can easily damage the fibers of the clothes and very easily damage the clothes. For example, the formula disclosed in document No. CN118085969A "A laundry detergent formula and its production process" contains water, sodium fatty alcohol polyether sulfate, inorganic salt detergent, fatty alcohol polyether-9, citric acid, flavor, preservative, pigment, etc. The inventive formula has the advantages of strong decontamination, softness, anti-scaling, high cost performance, etc., but the decontamination effect of this patented formula on stubborn stains still has room for improvement; Document No. CN117946821A "A stable weakly acidic concentrated laundry detergent and its preparation method" discloses a sulfonic acid-free, green, mild weakly acidic concentrated laundry detergent, but it uses a variety of surfactants, and the total surfactant content reaches more than 44%, so its cost is relatively high; the formula in document No. CN117866712A "An antibacterial and antibacterial fragrance laundry detergent" contains anionic surfactants, nonionic surfactants, deionized water, mixed biological enzymes, ethylenediaminetetraacetic acid, spices and other ingredients. The mixed biological enzyme in the invention improves the antibacterial and antibacterial effect of the laundry detergent through the synergistic effect of mannanase, juice decomposing enzyme and PDE phosphodiesterase. Its main innovation is to use the synergistic effect of enzymes to achieve the antibacterial and antibacterial effect, reducing the use of antibacterial agents, but there is no research on the synergistic effect of detergency; the document number CN117801894A "A laundry detergent composition for efficiently removing blood stains and its preparation method" has developed a laundry detergent composition for stubborn blood stains. The laundry detergent contains surfactants such as sodium octyl sulfonate, tetrasodium glutamate diacetate, sugar alcohol surfactants, fatty alcohol polyoxyethylene ether sulfate, as well as preservatives, pH adjusters, flavors, pigments and other additives, enzyme preparations, etc. It mainly improves the decontamination ability of blood stains through the synergistic effect of enzymes such as sodium octyl sulfonate and maltooligosaccharide glucoside, but the washing method used is through strong stirring, which causes certain damage to clothes when used in actual life.

[0035] The decontamination composition provided in this embodiment is similar to the laundry detergent currently sold on the market. It is a concentrated liquid. A small amount of the decontamination composition can be added to the water each time the clothes are washed. According to the water consumption, 0.5-2L (it can be any value among 0.5L, 0.6L, 0.7L, 0.8L, 0.9L, 1L, 1.1L, 1.2L, 1.3L, 1.4L, 1.5L, 1.6L, 1.7L, 1.8L, 1.9L and 2L or the corresponding range between any two values) of the decontamination composition can be added to every 100L of water.

[0036] The effects of each component in this embodiment are as follows:

[0037] Fatty alcohol polyether sulfate: As the main surfactant, it combines with stain components such as grease through its lipophilic group to form micelles, which wrap the stains and allow them to disperse into the water, achieving the effect of cleaning and decontamination;

[0038] Acrylic acid polymers and polyethylene glycol: their molecular structures contain a large number of hydrophilic groups and hydrogen bond donors, forming a stronger film on the surface of the fabric and a structure with a certain suspension effect in water. Therefore, they can replace the stains on the surface of the fabric while preventing the stains from being adsorbed on the fabric again, thereby enhancing the decontamination effect of the surfactant;

[0039] Raffinose: It can form a protective layer around enzymes and other protein molecules to prevent the molecular structure or conformation of the enzyme from changing and losing its activity. At the same time, raffinose has a good affinity with fabrics, which is conducive to adsorbing the enzyme to the binding site between the stain and the fabric, decomposing the binding site of the stain, making the binding between the stain and the cotton fabric loose, thereby improving the decontamination effect;

[0040] Potassium cocoyl glycinate and potassium cocoate: As auxiliary surfactants, because the main surfactant is too single, it has poor ability to bind, micellize and encapsulate certain components of stains. Choosing a suitable auxiliary surfactant can work synergistically with the main surfactant to enhance the encapsulation ability of different stains and improve the cleaning effect.

[0044] The fatty alcohol in the sodium fatty alcohol polyether sulfate in this embodiment mainly includes lauryl alcohol (dodecanol), myristyl alcohol (tetradecanol), cetyl alcohol (hexadecanol), stearyl alcohol (octadecyl alcohol), etc. Specifically, the chemical formula of sodium fatty alcohol polyether sulfate is RO (CH 2 CH 2 O)n-SO 3Na, where R represents a fatty alcohol portion. The fatty alcohol portion can be lauryl alcohol (dodecanol), myristyl alcohol (tetradecanol), cetyl alcohol (hexadecanol), stearyl alcohol (octadecyl alcohol), etc. Lauryl alcohol is a common fatty alcohol, and its chemical name is dodecanol, a straight-chain saturated fatty alcohol with 12 carbon atoms. Hexadecanol, also known as cetyl alcohol, is another fatty alcohol, a straight-chain saturated fatty alcohol with 16 carbon atoms.

The cleaning method was to soak the bloodstained cloth in the diluent for 30 minutes, then take it out immediately and rinse it with tap water for 15 seconds, then dry it and iron it, and then take pictures, and use ImageJ software to perform image analysis, and obtain the average grayscale of the stained area on the bloodstained cloth corresponding to each embodiment and comparative example (its grayscale is c, and the c value corresponding to each embodiment and comparative example is different), and take undyed white cotton cloth as a benchmark (its grayscale is a constant value a), and take the average grayscale of the stained area of ​​the bloodstained cloth treated with comparative example 1 (its grayscale is a constant value b) as a control, and calculate the dirt residue rate of the stained area on the bloodstained cloth corresponding to each embodiment and comparative example relative to comparative example 1 = (ca) / (ba)*100%, wherein the c value corresponding to comparative example 1 is equal to the b value, that is, the dirt residue rate of comparative example 1 is 100%. The specific results are shown in Tables 1 and 2.

[0050] The method for making the bloodstained cloth is to take a piece of white cotton cloth, then drip a drop of blood (it can be pig blood or chicken blood, of course not limited to this) in the middle of it, and then dry it at 50°C for 24 hours to obtain the bloodstained cloth.
