Problems solved by technology

The multi-purpose cleaning agents sold on the market still use synthetic surfactants as the main surfactant; this type of surfactant is usually poor in biodegradability, and because most of the raw materials come from petroleum, it also has certain effects on human health. adverse effects of
[0005] Although tea saponin is a natural surfactant, its practical application in cleaning agents is not extensive. A large part of the factor is due to the influence of tea saponin on the properties of surfactants. Medium to high, strong foaming performance, not conducive to rinsing, etc. Therefore, it is necessary to modify the structure of tea saponin, improve its performance, and increase the utilization value of tea saponin

Embodiment 1

[0031] Embodiment 1: the synthesis of tea saponin polyoxyethylene laurate

[0032] Step 1: Add tea saponin, DMF and MCT-09 into the reaction kettle, replace the air in the reaction kettle with inert gas, heat up to 140°C, add ethylene oxide, and cool down to At room temperature, vacuumize, filter the reaction solution to remove the catalyst, concentrate the reaction solution and add it to petroleum ether to precipitate a solid, and dry the obtained solid after filtration, and the obtained solid is tea saponin polyoxyethylene ether.

[0033] The feed amount and product quality of each reactant are shown in Table 1 below.

[0034] Table 1:

Embodiment 2

[0041] Example 2: Preparation of Multipurpose Cleaner

[0042] Add isomeric undecyl alcohol polyoxyethylene ether to 50 grams of water, heat up to 60 degrees Celsius, add polyethylene glycol under stirring, dissolve completely, keep this temperature, slowly add tea saponin polyoxyethylene laurate ( Prepared by Experiment 8), continue to stir until the dissolution is complete, then add polyether 61 and carboxymethyl cellulose, stir to dissolve, dissolve sodium silicate and sodium citrate with the least amount of water, add to the above solution, make up the remaining water to 100 grams, continue to stir for half an hour, and obtain a multi-purpose cleaning agent after cooling .

[0043] The proportion of specific multi-purpose cleaning agent is shown in Table 3 below.

[0044] Table 3 (unit: gram):

[0045] Recipe 1 Recipe 2 Recipe 3 Recipe 4 Recipe 5 Tea saponin polyoxyethylene laurate 10 10 15 15 20 Isomerized undecyl alcohol polyoxyethyl...

Embodiment 3

[0047] Refer to QB / T 4532-2013 hard floor cleaning agent 3.2.3 to test the stability; the method of measuring detergency in Appendix A is to test the detergency. The cleaning agent of each formula is diluted to 1% with water, parallel Three sets of experiments were carried out, and the average value was taken as the detergency; the pH was measured by the potentiometric method according to the provisions of GB6368; the obtained results are shown in Table 4 below.

[0048] Table 4:

[0049]

[0050] It can be seen from the above test results that the detergency of the multi-purpose cleaning agent of the present invention can reach more than 90%, and the detergency of formula 4 is higher than other formulas, up to 96%.

[0051]The tea saponin polyoxyethylene laurate obtained in Experiment 6, Experiment 7, Experiment 9, and Experiment 10 has different HLB values, so the optimal ratio is the tea saponin polyoxyethylene laurate corresponding to Experiment 8. There may be some di...

Abstract

The invention discloses a multipurpose cleaning agent containing tea saponin polyoxyethylene laurate and a preparation method of the multipurpose cleaning agent. The multipurpose cleaning agent comprises the following components by mass ratio: 10 to 20 parts of tea saponin polyoxyethylene laurate, 10 to 15 parts of isomeric undecanol polyoxyethylene ether, 0.5 to 1.5 parts of sodium silicate, 3 to5 parts of sodium citrate, 0.5 to 1.5 parts of polyether 61, 0.5 to 1 part of carboxymethyl cellulose, 0.1 to 0.3 part of polyethylene glycol and the balance of water. The multipurpose cleaning agenthas the advantages of strong detergency, high stability, safety in use, biodegradability, greenness, environmental protection and no VOC emission, the use of the tea saponin is expanded by using thesurfactant modified by the natural tea saponin, natural renewable resources are effectively utilized, and the concept of sustainable development is met.

Description

technical field [0001] The invention relates to the technical field of surfactants and cleaning agents, in particular to tea saponin-modified surfactants and multipurpose cleaning agents, in particular to a multipurpose cleaning agent containing tea saponin polyoxyethylene laurate and its preparation method. Background technique [0002] Tea saponin, also known as tea saponin, is a kind of glycoside compound extracted from tea tree seeds (tea seeds, tea seeds). It is a natural surfactant with good performance. It can be widely used in light industry, chemical industry, Pesticides, feed, breeding, textiles, oil extraction, mining, building materials and highway construction and other fields. [0003] It has been proved by research that the HLB value of tea saponin is about 16, which can significantly reduce surface tension, has good detergency and wetting ability, and has strong foaming ability and foam stabilizing performance. Easy to biodegrade, it is a kind of green natu...
