Description

Technical Field

[0001] The invention relates to the technical field of instant oxygen bleaching laundry, and more particularly to a mild and environment-friendly instant oxygen bleaching laundry block. Background Art

[0002] Detergent is a product specially formulated for cleaning through the washing process. Its main components are usually composed of surfactants, builders and additives. There are many types of detergents. According to the type of dirt removed, they can be divided into heavy-duty detergents and light-duty detergents. According to the appearance of the product, they can be divided into powder, block, paste, slurry and liquid. Practice has proved that only anionic surfactants and non-ionic surfactants can play a positive and effective role in fabric decontamination in fabric washing. Therefore, these two surfactants become the main materials of clothing detergents. Detergents must have good wettability, permeability, emulsification, dispersibility, solubilization, foaming and defoaming properties. The combination of these properties is the washing performance of the detergent. There are many types of detergent products, which can basically be divided into soap, synthetic washing powder, liquid detergent, solid detergent and paste detergent. Different from household detergents, professional detergents are an independent classification, mainly including detergents for hotels, hospitals and hotels, which are used for the needs of large-scale washing industries such as laundries. Including cleaning agents for public facilities, textile industry cleaning agents, leather cleaning agents, food industry cleaning agents, transportation cleaning agents, metal cleaning agents, optical glass cleaning agents, plastic and rubber cleaning agents and other industrial cleaning agents.

[0003] For example, the patent document with the announcement number CN 108624417 B discloses a quick-dissolving and easy-rinsing soft laundry detergent. It is calculated by mass percentage and includes the following components: 0.20-2.00% potassium cocoate, 0.01-3.00% cationic surfactant, and 0.01-3.00% amino-modified silicone softener, wherein the cationic surfactant is any one of alkyl ethyl dimethyl ammonium chloride, cationic modified cellulose, and ester quaternary ammonium salt, or a combination of at least two of them. The present invention has the properties of quick dissolution, easy rinsing, and softness, which can effectively save washing time and washing water, and achieve energy conservation and environmental protection; washing and softening are done in one step, simplifying the washing steps, saving time and worry. The present invention is particularly suitable as a soft laundry detergent product for infants and children, meeting the growing market demand for infant and child washing products.

[0004] However, the three main types of laundry detergents commonly used in life at present are washing powder, laundry liquid and laundry soap. Among them, washing powder is usually packaged in bags. When using, the packaging bag is cut open, a small amount of washing powder is taken out, and then the packaging bag is clamped with items such as clips. This kind of washing powder has poor sealing after the packaging bag is opened, which easily causes the washing powder to get damp and clump, thereby affecting its solubility and cleaning power. In addition, the washing powder is also very easy to scatter outside during the use process, which is difficult to clean. In addition, consumers generally add washing powder by pouring, resulting in inaccurate amount of washing powder added. Washing liquid is usually bottled and measured with a measuring cup when taking it out. There is also an extrusion-type bottled washing liquid. The liquid outlet of this kind of washing liquid is easy to be squeezed due to multiple squeezing or extrusion head packaging problems. It is easy to cause the laundry detergent to overflow automatically after squeezing, which increases the cleaning work after washing. In addition, the laundry detergent is large in size and weight, occupies a large space and is laborious to pour. The laundry soap will retain moisture during the scrubbing process. After being placed in the soap box, the long-term retention of moisture will soften the laundry soap, causing unnecessary waste. In summary, traditional laundry detergents have various defects, are not easy to carry, take up space, and are especially inconvenient to use when traveling on business. At the same time, ordinary laundry products mainly rely on various chemical ingredients and surfactants to assist in decontamination. It can only remove stains on the surface of clothes, and the stains remaining in the fibers will precipitate more and more, which will make the clothes yellow and may also be harmful to the human body. Therefore, it is necessary to improve laundry supplies.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a mild and environmentally friendly instant oxygen bleaching laundry block. Summary of the invention

[0006] The existing laundry detergents mainly include three types: washing powder, washing liquid and laundry soap. Washing powder has poor sealing performance after the packaging bag is opened, which easily causes the washing powder to be damp and lumped, thereby affecting its solubility and cleaning power. In addition, the washing powder is also very easy to scatter outside during use, making it difficult to clean. The liquid outlet of the washing liquid is easy to cause the washing liquid to overflow automatically after squeezing due to multiple squeezing or squeezing head packaging problems, which increases the cleaning work after washing. The washing soap will retain moisture during the scrubbing process. After being placed in the soap box, the long-term retention of moisture will soften the washing soap, causing unnecessary waste. In summary, the traditional laundry detergent has various defects, is not easy to carry, occupies space, and is especially inconvenient to use when traveling on business. At the same time, ordinary laundry products mainly rely on various chemical components and surfactants to assist in decontamination. It can only remove stains on the surface of clothes, while more and more stains remaining in the fiber will precipitate, which will make the clothes yellow and may also be harmful to the human body.
