Description

Quick-washing residue-free laundry detergent and preparation method thereof Technical Field The invention relates to the technical field of detergents, in particular to a fast-washing residue-free laundry detergent and a preparation method thereof. Background With the acceleration of modern life pace and the enhancement of energy conservation and environmental protection consciousness, consumers are increasingly inclined to finish daily washing by using a quick washing mode so as to save time and water. However, the main stream of liquid laundry detergent formulations in the market at present are mostly designed for conventional washing procedures (30-60 minutes), and the following technical problems often exist under the short-time fast washing procedures: The decontamination system of the prior laundry detergent mostly depends on traditional anionic surfactants, such as linear sodium alkylbenzenesulfonate (LAS), fatty alcohol polyoxyethylene ether sodium sulfate (AES) and the like. These surfactant systems perform well in removing greasy dirt, proteinaceous stains, but require some time to adequately wet, disperse, and emulsify the soil. In the fast washing mode (10-15 minutes), the washing time is shortened, so that the surfactant does not fully play a role yet, the decontamination rate is obviously reduced, and especially the cleaning effect on sebum dirt, sweat stain and food oil stain is not ideal. In order to pursue high detergency, conventional laundry detergents often incorporate relatively foaming surfactant systems (e.g., aes+las) which are rich in foam but not easily sheeting. Under short-time rinsing, foam and part of active substances are easy to remain among fabric fibers, so that the problems that skin possibly has uncomfortable reactions such as itching, irritation and the like after wearing, the residues react with sweat to generate peculiar smell, and the long-term residues cause yellowing and hardening of clothes are caused. In addition, fluorescent whitening agents, phosphates, silicate or polycarboxylate synergists are added into part of the products, so that the apparent cleanliness can be improved, but the components are difficult to clean completely, potential safety hazards exist for infants and sensitive muscle groups, and the environment biodegradation is not facilitated. Therefore, there is an urgent need for a novel laundry detergent capable of achieving efficient soil removal under low temperature, short time conditions, and having little chemical residue after one rinsing. Disclosure of Invention The invention provides a fast-washing residue-free laundry detergent, and discloses a low-foam residue-free laundry detergent formula system suitable for a fast-washing program, which is characterized in that ethoxylated propoxylated C16-18 alcohol is adopted as a main surface active agent, and is cooperatively compounded with an anionic surfactant and a biological enzyme system, and a PEG-120 methyl glucose sesquistearate cooperative thickening system is combined to form a composite surfactant system with the characteristics of fast wetting, low foam rapid bleaching and no residue. Based on this, it is necessary to provide a fast-washing residue-free laundry detergent comprising the following components in mass fraction: 1-10% of diblock nonionic surfactant Anionic surfactant 4-15% Biological enzyme compound 0.2-1% 0.3 To 3 percent of thickening agent 1 To 15 percent of auxiliary agent A solvent balance; wherein the diblock nonionic surfactant is ethoxylated propoxylated C16-18 alcohol, and the structural general formula of the ethoxylated propoxylated C16-18 alcohol is shown as follows: R-O-(CH2CH2O)m-(CH2CH(CH3)O)n-H r is C 16-C18 alkyl; m is selected from 2-6; n is selected from 1-3; The thickener is PEG-120 methyl glucose sesquistearate. Specifically, the ethoxylated propoxylated C16-18 Alcohol (AEPO) belongs to a block nonionic surfactant, the Ethoxy (EO) chain segment of the surfactant can quickly reduce the interfacial tension to realize greasy dirt wetting and stripping, and the Propoxy (PO) chain segment can adjust the hydrophobicity of surfactant molecules to ensure that micelles still keep a stable dispersion structure under high shear and low concentration, so that quick washing and thorough rinsing are realized in a short time (less than or equal to 15 min). Further incorporation of PEG-120 methyl glucal sesquistearate provides good rheological stability while maintaining the transparency of the system. The system avoids the problems of foam stabilization, salting out or enzyme inactivation caused by the traditional high-salt thickening mode. By means of the ternary synergistic effect of AEPO, anionic surfactant and PEG-120 methyl glucose sesquistearate, the laundry detergent can realize triple performance balance of high detergency (more than or equal to 95%), low foam quick bleaching (one-time rinsing) and low residue (less than or equal to 0.02 wt%) in a short time,
