A blood stain removing mixture and a method for preparing the same

Abstract

This invention discloses a blood stain remover mixture and its preparation method. It employs a multi-enzyme synergistic compound system. Protease directionally decomposes hemoglobin and protein in blood stains, amylase decomposes polysaccharide deposits in the blood, and a binary complex enzyme assists in decomposing lipids and cross-linked proteins within the blood stains. The synergistic effect of these multiple enzymes rapidly breaks down dried blood stains, removing them thoroughly without leaving any yellow residue. A composite surfactant system is formed by combining surfactants, sodium lauryl ether sulfate, and sodium urate, enhancing the wetting and penetration capabilities of fabrics and promoting rapid penetration of the enzyme preparation into the fiber interior. The overall formula is mild and low-irritant, free of strong alkalis and chlorine bleach, protecting various fabrics such as silk, cotton, and linen. The added seashell powder serves as a functional additive, gently peeling away coagulated blood stains from the fiber surface, adjusting the system's pH value, stabilizing enzyme activity, and extending the product's shelf life.

Description

Technical Field

[0001] This invention belongs to the field of laundry detergent technology, specifically relating to a mixture that removes blood stains and its preparation method. Background Technology

[0002] In daily life, textiles such as clothing, sheets, and duvet covers are easily stained with blood. Blood stains are mainly composed of hemoglobin, protein, lipids, and other organic substances. After blood dries, the protein adheres firmly to the fabric fibers. Conventional laundry detergents and powders, relying on a single surfactant, are unlikely to completely break down stubborn blood stains, leaving yellow or red marks after washing that cannot be completely removed even with repeated washing. Existing blood stain removal products have the following drawbacks: they use chlorine bleach and strong alkaline additives, which are highly irritating and easily damage cotton, linen, silk, and wool fibers, causing whitening and tearing of the fabric; they only add a single protease, resulting in a limited substrate and failing to simultaneously break down lipids and polysaccharides attached to the blood stain, leading to low cleaning efficiency; the enzyme preparation has poor compatibility with surfactants, and enzyme activity rapidly declines during storage, significantly reducing cleaning effectiveness after long-term standing; the formula is highly irritating, leaving irritating residues after washing intimate sheets and underwear, which can cause redness and itching upon skin contact. Therefore, the industry urgently needs a cleaning mixture that is multi-enzyme compounded, has stable compatibility, is mild and low-irritant, and can quickly decompose stubborn bloodstains. Summary of the Invention

[0003] In view of this, the main objective of the present invention is to provide a mixture that removes blood stains.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows: Embodiment 1 of the present invention provides a mixture for removing blood stains, which is composed of the following raw materials in weight percentage: surfactant 10-14%, sodium lauryl ether sulfate 3-5%, sodium urethane 1-1.6%, protease 0.4-0.8%, binary complex enzyme 0.1-0.3%, amylase 1-1.6%, seashell powder 1-1.8%, and the balance being deionized water, with the total weight percentage of each component being 100%.

[0005] In the above scheme, the weight percentage of each raw material is as follows: surfactant 12%, sodium lauryl ether sulfate 4%, sodium urethane 1.3%, protease 0.6%, binary complex enzyme 0.21%, amylase 1.3%, seashell powder 1.4%, and the balance is deionized water.

[0006] In the above scheme, the weight percentage of each raw material is as follows: surfactant 11%, sodium lauryl ether sulfate 3.5%, sodium urethane 1.2%, protease 0.5%, binary complex enzyme 0.18%, amylase 1.2%, seashell powder 1.3%, and the balance is deionized water.

[0007] Embodiment 2 of the present invention provides a method for preparing the above-mentioned mixture with blood stain removal properties, comprising the following steps: S1. Premixing: Mix the surfactant, sodium lauryl ether sulfate, sodium amino acid and deionized water evenly to obtain a preliminary mixture; S2. Dissolving and Adding: Add protease, binary complex enzyme, amylase and seashell powder to the preliminary mixture, and continue stirring until all raw materials are completely dissolved to obtain the final mixture; S3. Post-processing: The final mixture is left to stand in the dark for 24 hours, stirred again, filtered, and filled to obtain the finished product.

[0008] Compared with existing technologies, this invention employs a multi-enzyme synergistic compound system. Protease directionally decomposes hemoglobin and protein in blood stains, amylase decomposes polysaccharide deposits in blood, and binary complex enzymes assist in decomposing lipids and cross-linked proteins within blood stains. The synergistic effect of multiple enzymes can quickly break down dried blood stains, removing them thoroughly without leaving any yellow residue. Combined with surfactants, sodium lauryl ether sulfate, and sodium urate to form a complex surfactant system, it enhances the wetting and penetration ability of fabrics, promoting the rapid penetration of enzyme preparations into the fiber interior. The overall formula is mild and low in irritation, free of strong alkalis and chlorine bleach, and can protect various fabrics such as silk, cotton, and linen. The added seashell powder, as a functional additive, can gently peel off coagulated blood stains on the fiber surface, adjust the pH value of the system, stabilize enzyme activity, and extend the product's shelf life.
