In the specific preparation processes, the sodium carboxymethyl cellulose is added in step 2, the soybean liquid lecithin and/or ethylene glycol distearate is added in step 3, and the sodium stearate and/or Kathon is added in step 4. The regulating agent used for adjusting the pH of the system in the above-mentioned preparation method was acetic acid or citric acid.

[0042] The multipurpose, highly effective and environmentally-friendly cleaning fluids prepared in the above-mentioned Examples 1 to 7 were tested by the National Processed Food and Food Additive Quality Inspection Center (Nanjing) at the Nanjing Institute of Product Quality Inspection, with reference to the standard GB 9985-2000 Detergents for hand dishwashing. The test conclusions were that the total content of active substances was more than 16%, the pH (25 C., 1% solution) was 7.0 to 7.2, no formaldehyde was detected, and the detergencies of all the fluids were greater than those of standard dish washing detergents.

[0043] In accordance with the tests for the criteria of HJ636-2012 and GB11893-89, the amounts of ammonia nitrogen contained were zero according to the HJ636-2012 test, and the amounts of phosphorus contained were zero according to the GB11893-89 test.

[0044] An acrylic paint/lacquer film test plate was immersed in the cleaning fluid and soaked for 2 days. The test result was as follows: the paint/lacquer film showed no discoloration, blistering, or peeling, no loss of lustre, and no difference in colour.

[0045] A series of performance comparison and verification tests were carried out during the research and development process of the invention; and in order to further illustrate the performance effect of the multipurpose, highly effective and environmentally-friendly cleaning fluid provided by the present invention, several typical examples of these have been selected and are illustrated below:

[0046] The vehicle cleaning performance of the cleaning fluid prepared in Example 4 of the present invention and of a product obtained from the domestic application patent of application No 201510209702. 5 were compared. The details were as follows:

[0048] The furniture cleaning performances of the cleaning fluid prepared in Example 4 in the present invention and a product obtained by the domestic application patent of application No 201410699255.1 were compared. The details were as follows:

[0049] The inventors carried out a series of performance comparison tests on the multipurpose, highly effective and environmentally-friendly cleaning fluid provided by the present invention during the development process, and several Examples were selected and are described below:

Test 1

[0050] Sodium dioctyl sulfosuccinate, sucrose ester, alkyl phenol polyoxyethyl ether, fatty alcohol polyoxyethylene ether, sodium diisobutyl sulfosuccinate, sodium dodecyl benzene sulfonate, and ammonium nonylphenyl polyoxyethylene ether sulfate were used as surfactants instead of the surfactants in the present invention. Vehicle cleaning fluids were prepared by adding two or three of the above surfactants to the formulation instead of the surfactants in Example 1 of the present invention, and were used for cleaning the surface of a vehicle. The test results show that the speed and thoroughness of dirt removal of these cleaning fluids were lower than the speed and thoroughness of dirt removal of the cleaning fluid in Example 1. At the same time, on removing the sodium polyacrylate component from Example 1, the performance of the prepared cleaning fluid was significantly lower than the performance of the cleaning fluids obtained in Example 1. The explanation is that the surfactants provided in the present invention and the sodium polyacrylate mutually achieve a synergistic effect, together improving the cleaning performance. The research of the present invention shows that in the cleaning process, the sodium polyacrylate can provide alkaline buffering conditions and at the same time can chelate the metal ions in the dirt, providing a coagulation effect, so that general dirt, grease, dust and the like combine more easily with the surfactants provided in the present invention, which efficiently accelerates the cleaning, and at the same time, make difficult-to-clean dirt and grease and the like combine more easily with the surfactants in the present invention, which improves the cleaning efficiency. Further studies have found that the surfactants in the cleaning fluid of the present invention not only act to remove dirt rapidly, but also enhance the lustering effect of ethylene glycol distearate.

Test 2

[0051] After cleaning an object using the cleaning fluid prepared with a formulation of the present invention, but with no addition of sodium stearate, some lustrous effect formed on the surface of the object, but the degree of lustre was poor. On wiping using only little effort, it was clearly to be seen that the lustre had been destroyed; while after the surface of the cleaned object had been left to dry naturally, the lustrous layer on the surface was easily dirtied, indicating that the lustre stability was not good. Following the addition of sodium stearate however, a dense protective film was left on the surface of the object after cleaning and the stability of the film was very good, moreover the stability of the film after wiping dry was very good, and the film did not readily become dirty. The explanation is that both the sodium stearate and the ethylene glycol distearate used in the present invention can have a synergistic effect in the cleaning fluid system provided by the present invention to achieve better coating film lustre effects.
