Bathroom cleaning agent and preparation process thereof

Technical Field

The invention relates to the technical field of cleaning lotions, in particular to a bathroom cleaner and a preparation process thereof.

Background

The dirt in the bathroom is mainly caused by the adhesion and accumulation of the fallen human skin, sebum, dust, bacteria and the like on ceramic tiles, glass and floor tiles and air drying. Such dirt is generally difficult to clean because of its high adhesion, and thus, a cleaner used for cleaning the dirt in a bathroom is required to have a high cleaning power.

Chinese patent application with application number of 200810222880.1 and application date of 2008, 09 and 24 discloses a cleaning agent, which comprises the following main active components in parts by weight: 10-20 parts of nonionic surfactant, 0.5-5.5 parts of anionic surfactant, 2-5 parts of methanesulfonic acid, 0.3-1.0 part of thiourea and 2-15 parts of hydrogen peroxide.

Although the prior art has a good cleaning effect, because the cleaning agent contains methanesulfonic acid and the content of the methanesulfonic acid in the cleaning agent is high, the cleaning agent has strong corrosivity to metals, and the bathroom can not avoid the existence of common metal parts (such as iron and copper), such as the supporting legs of a wash stand are made of copper, and if the prior art is used for cleaning, the part of the structure is easy to corrode to different degrees. Meanwhile, thiourea used in the prior art also has strong toxic action and is not beneficial to human health.

Disclosure of Invention

In view of the disadvantages of the prior art, a first object of the present invention is to provide a bathroom cleaner which has an excellent ability to remove dirt while not easily damaging metal parts such as iron, copper, etc. in a bathroom.

A second object of the present invention is to provide a process for preparing a bathroom cleaner, which has a uniform texture and a moderate viscosity, and which has good penetration and detergency, and also makes it convenient to use.

In order to achieve the first object, the invention provides the following technical scheme:

a bathroom cleaner comprises the following components in parts by weight:

5-30 parts of dodecyl benzene sulfonic acid;

5-40 parts of a first penetrating agent;

6-50 parts of a second penetrating agent;

1-10 parts of a buffering agent;

a pH adjusting agent;

6.5-23.1 parts of deionized water;

the first penetrant comprises at least one of diethanolamine and triethanolamine;

the second penetrant consists of N-methyl pyrrolidone and dipropylene glycol butyl ether;

the bath cleanser has a pH of 8.5-11.

By adopting the technical scheme, in the first penetrating solvent, the diethanol amine has better corrosion inhibition performance, can also be used as an acid absorbent to be matched with the pH regulator and the buffer, and is favorable for keeping the bathroom cleaner in an alkaline condition. The triethanolamine has good stability and no corrosiveness to copper parts and iron parts.

Meanwhile, the diethanol amine and the triethanolamine have good permeation effects, can play a good role in permeating dead skin and dirt which is difficult to scrape off due to grease attached to the ceramic tile, and enables the dirt to be separated from the surface of the ceramic tile.

In the second penetrating agent, the N-methyl pyrrolidone has small smell, low volatility and good penetrating effect; the dipropylene glycol butyl ether has small smell, good fluidity and stability, is not easy to decompose under the conventional condition, and can quickly permeate in oil and fat substances. Therefore, the N-methyl pyrrolidone and the dipropylene glycol butyl ether are matched with each other, and have better penetration effect than the N-methyl pyrrolidone and the dipropylene glycol butyl ether when the N-methyl pyrrolidone and the dipropylene glycol butyl ether are used respectively.

First penetrant and second penetrant in this application cooperate each other, can effectively reduce the smell of bathroom sanitizer, are favorable to increasing user experience and feel.

The buffer agent comprises at least one of disodium ethylene diamine tetraacetate and tetrasodium ethylene diamine tetraacetate, and is helpful for keeping the pH value of the whole liquid-phase system in the range of 8.5-11.

The bathroom cleaners in this application have a low odor, unlike conventional cleaners, which, while having good stain removal cleaning ability, are accompanied by a harsh taste. Meanwhile, the first penetrating agent and the second penetrating agent are matched with each other, so that the penetration of dirt such as grease and skin which are remained and attached to the ceramic tiles is increased, the effective decontamination effect can be achieved, metal products are not easy to damage, and the bathroom cleaning agent has an excellent effect on keeping a bathroom clean.

Meanwhile, through the mutual matching of the first penetrating agent, the second penetrating agent and the buffering agent, the dirt can be thoroughly removed without water, and the paper towel or the rag is adopted for wiping, so that the water is saved, and the cleaning difficulty is reduced.

More preferably: the bathroom cleaner also comprises 0.2-2 parts of kasong and 0.2-2 parts of essence by weight.

By adopting the technical scheme, the kasong is used for corrosion prevention, and the essence is used for bringing good air refreshing feeling to a bathroom.

By adopting the technical scheme, the sulfonated oil (sulfonated oil SS) has good stability, acid and alkali resistance and other electrolytes; and it helps to dissolve the water-insoluble fats and oils. The water in the detergent or the water in the detergent solution formed by the detergent and water can promote the degradation of the oil and fat by the sulfonated oil and help to promote the penetration effect of the components in the detergent in dirt.

And the sulfonated oil can form a compound action with the first penetrant and the second penetrant, so that the penetration and decontamination capability of the bathroom cleaner are further enhanced.

More preferably: the bathroom cleaner also comprises 1-3 parts of sodium lauroyl sarcosinate by weight.

By adopting the technical scheme, the sodium lauroyl sarcosine (N-sodium lauroyl sarcosine) has excellent antibacterial and bactericidal effects, can directly kill bacteria on the surface of dirt after contacting the dirt, and is beneficial to enabling a cleaning agent to enter along gaps left by killed bacteria and separating the dirt from the surface of a ceramic tile or a floor tile.

And the addition of the N-sodium lauroyl sarcosine is beneficial to reducing the irritation and the smell of the cleaning agent, enhancing the penetrating function of the cleaning agent, being beneficial to the penetrating effect of other components in the cleaning agent and being more beneficial to removing dirt such as sebum and the like.

Sodium lauroyl sarcosinate (N-sodium lauroyl sarcosinate) can also form a better matching effect with sulfonated oil, so that the dissolving effect on the oil is increased.

More preferably: the bathroom cleaner also comprises 2-3 parts by weight of polyvinyl alcohol.

By adopting the technical scheme, the cleaning agent is favorable for forming a film-shaped object after being sprayed, and is more favorable for bringing down the dirt integrally in the wiping process, so that the residue is not easy to appear, and the dirt is convenient to remove.

In addition, the garbage classification is very important for environmental protection, the dirt is integrally cleaned and then thrown into the garbage can, the garbage can is conveniently and pertinently treated in a centralized mode, the garbage does not need to be washed by excessive clear water, therefore, chemical components in bathroom cleaning agents enter a sewer pipe along with water flow, and the subsequent sewage treatment is facilitated.

And after the film-like material is formed, other components are less likely to be excessively volatilized, and the effectiveness of the components can be maintained.

In order to achieve the second object, the invention provides the following technical scheme:

step two, fully mixing a buffering agent, a pH regulator and the first mixture obtained in the step one to obtain a second mixture;

and step three, fully mixing the second penetrating agent and the second mixture, and adjusting the pH value to 8.5-11 to obtain the bathroom cleaner.

By adopting the technical scheme, in the first step, the sodium dodecyl benzene sulfonate, the first penetrating agent and the deionized water are mixed together, so that the sodium dodecyl benzene sulfonate and the first penetrating agent form good matching. In the second step, the formed system of the second mixture is kept stable under the coordination of the buffer solution and the pH regulator.

After the second penetrating agent and the second mixture are mixed, and the pH value is kept in the range of 8.5-11, the second penetrating agent, the first penetrating agent and the sodium dodecyl benzene sulfonate can be matched with each other, so that the bathroom cleaner achieves a good stable effect.

More preferably: in the third step, the kasong and the essence are fully mixed with the second mixture, and then fully mixed with the second penetrating agent.

By adopting the technical scheme, the obtained bathroom cleaning agent has longer shelf life and fragrance.

Comparative example

Comparative example 1: a detergent different from example 1 in that example 1 of chinese patent application having application No. 200810222880.1 and application date of 2008, 09 and 24 was used as comparative example 1.

Comparative examples 2 to 4: a cleaning agent, which is different from example 1 in that the components contained and their corresponding masses are shown in table 2.

Table 2 components contained in comparative examples 2 to 4 and their corresponding masses

Test one: detergency test a simulated mixture for testing was prepared: a simulated mixture for testing was obtained by mixing 0.05g human epidermis, 0.5g lard, 10g water at 37 ℃ together, adding 1g baking soda and remixing.

Self-control ceramic tile for experiment: preparing 15 parts of simulation mixture in the same way, preparing 15 ceramic tiles with the specification of 20mm multiplied by 20mm, uniformly paving all the simulation mixture on the ceramic tiles, and naturally drying for 72 hours to obtain ceramic tile samples; then, in a constant temperature and humidity environment at a temperature of 25 ℃ and a humidity of 65% RH, 15 tile samples were allowed to stand for 30 days to obtain test tiles.

Test samples: selecting the example 1, and preparing according to the mixing ratio of the example 1 to water being 1:8 to obtain a test sample 1; test samples 2-11 were prepared in the same manner. Selecting a comparative example 2, and preparing according to the proportion of 1:8 between the comparative example 2 and water to obtain a comparative example 2; controls 2-4 were prepared in the same manner.

The test examples 1-11 were not pungent in odor and had viscosities of 300 + -20 cP, with example 1 having a viscosity of 300cP and examples 5, 10, 11 having a viscosity of 320 cP.

The test method comprises the following steps: uniformly spraying 10mL of the test sample 1 on a test tile, wiping the test tile by using non-woven fabric after 5s, and observing the clearance rate of dirt; test samples 2-11 and control samples 1-4 were tested in the same manner, and the clearance was recorded and analyzed.

And (3) test results: the removal rates of the test samples 1 to 11 and the control samples 1 to 4 for the fouling are shown in Table 3.

TABLE 3 cleaning of fouling by test samples 1-11 and by control samples 1-4

Test sample	Clearance rate/%)	Test ofSample (I)	Clearance rate/%)
				Test sample 1	91	Test sample 9	96
Test sample 2	89	Test specimen 10	97
				Test sample 3	94	Test specimen 11	92
Test sample 4	96	Control 1	92
				Test sample 5	98	Control 2	36
Test sample 6	93	Control 3	52
				Test sample 7	93	Control 4	65
Test specimen 8	96	/	/

As is clear from Table 3, the test samples 1 to 11 exhibited higher removal rates of fats and oils, dead skin and the like than the control samples 1 to 4.

Compared with the test samples 3-5, the use of the sulfonated oil, the N-sodium lauroyl sarcosine and the polyvinyl alcohol is increased one by one, so that the penetration and decontamination capability of the sulfonated oil, the N-sodium lauroyl sarcosine and the polyvinyl alcohol are improved one by one.

In comparison with the test sample 8 and the test sample 5, because the diethanolamine and triethanolamine in the first penetrant of the test sample 8 are not used in combination, the penetration and the detergency of the test sample 8 are inferior to those of the test sample 5.

In comparison with the test sample 11 and the test sample 5, the tetrasodium edta and the disodium edta in the second penetrant in the test sample 11 are not used in combination, so that the penetration and the stain removal capability of the test sample 11 are inferior to those of the test sample 5.

The clearance in the control samples 1-4 was lower than that of the test samples 1-11, mainly for the following reasons: compared with control 1 and test 1-11, the clearance rate was slightly higher than that of test 2, but the taste was strong and uncomfortable to the human body.

In comparison with control 2 and test 1-11, the detergency ratio was lower than that of test 1-11 because only dodecylbenzenesulfonic acid was contained therein to achieve the detergency effect.

Compared with control 3 and test 1-11, the detergent of the present invention has a slightly higher detergency than that of control 1, but lower detergency than that of test 1-11, because it contains more dodecylbenzene sulfonic acid than that of control 1 and is used in combination with a buffer.

Compared with the control 4 and the control 2, although the dosage of the dodecylbenzene sulfonic acid is lower than that of the dodecylbenzene sulfonic acid in the control 2, the dipropylene glycol butyl ether is also added, so that the decontamination rate of the control 4 is slightly higher than that of the control 2, which also shows that the dodecylbenzene sulfonic acid and the dipropylene glycol butyl ether can realize certain decontamination effect. However, in comparison with examples 1-11, the interaction of dodecylbenzene sulfonic acid with dipropylene glycol butyl ether alone was not comparable to the interaction of dodecylbenzene sulfonic acid with the first penetrant, the second penetrant, and even with sulfonated oil, sodium lauroyl sarcosinate, and polyvinyl alcohol.

In addition, the simulation mixture is continuously coated on the cleaned test tiles, after 1 hour of drying, the water on each tile is evaporated, and then the tile is wiped by the non-woven fabric which is dried, so that the simulation mixture on the tile cleaned by the test samples 1-11 is easier to wipe clean by the non-woven fabric, and the solid components in the simulation mixture remained on the tile cleaned by the control samples 1-4 are not easy to wipe clean by the non-woven fabric. The difference shows that the test samples 1 to 11 not only have excellent dirt removing capability, but also can fully permeate dirt such as grease and the like adhered to the surface of the ceramic tile, so that impurities are not easy to remain on the surface of the ceramic tile, and a protective layer is formed on the surface of the ceramic tile and is not easy to be tightly adhered by the dirt such as the grease and the like, thereby being beneficial to next cleaning.

And (2) test II: damage test on copper sheet

The test method comprises the following steps: taking the test sample in the first test as the test sample in the second test, spraying 5mL of the test sample 1 on the surface of a horizontally placed and bright square copper sheet with the length of 10cm, wiping the surface clean by using non-woven fabric after 5s, repeating the operation once every 1h and 100 times, observing the condition of the copper sheet and recording; test samples 2 to 11 and control sample 1 were tested in the same manner, recorded and analyzed.

And (3) test results: the effects of test samples 1-11 and control sample 1 on copper sheets are shown in Table 4.

TABLE 4 influence of test samples 1-11 and control sample 1 on copper sheets

As can be seen from Table 4, the test samples 1-11 prepared from the raw materials have good decontamination capability and are not easy to damage the copper sheet, while the control sample 1 has rusty spots with a large area, which indicates that the bathroom cleaner prepared from the components in the application is more friendly to the copper sheet and has a wider application range.
