Description

A kind of bathroom cleaner and preparation method thereof

technical field

The invention belongs to the technical field of cleaning agent production, and in particular relates to a bathroom cleaning agent and a preparation method thereof.

Background technique

The composition of bathroom dirt mainly includes scale, human body sebum, soap scum, etc. Among them, the most difficult to remove is the white block or powder scale. These scales are mainly carbonates, sulfates, chlorides and other compounds formed by calcium and magnesium ions in hard water at high temperatures, so they are also called calcium scales or magnesium scales. Calcium scales or magnesium scales are inorganic salts. Chemical properties are similar.

In order to reduce the corrosive effect of cleaners on glass, ceramics, stainless steel and other facilities in the bathroom, and at the same time efficiently remove the dirt in the bathroom, organic acids are widely selected as the main component of bathroom cleaners in the market. Malic acid, citric acid, and oxalic acid are the most commonly used organic acids, which are often added to formulas individually or in combination to become the main body of detergents. Bathroom dirt is difficult to remove after long-term accumulation, adhesion and weathering, and such organic acids are slightly weaker than inorganic acids such as hydrochloric acid and sulfuric acid. Therefore, in order to achieve the same cleaning effect as the inorganic acid, the amount of organic acid added is often greatly increased.

The organic acid itself has a sour taste. After a large amount of organic acid is added to the composition of the detergent, the acidity of the detergent itself is stimulated correspondingly. When the detergent product is used in a space with limited ventilation such as the bathroom, the human nasal mucosa will be Very uncomfortable due to the sour smell.

The existing technologies for reducing the irritation of cleaning agents are mainly divided into the following aspects: (1) Add deodorant, environmentally friendly biological enzymes, etc. to the components of cleaning agents to achieve the purpose of reducing the irritation of cleaning agents. (2) Add ingredients such as neutralizer to the composition of the detergent, so that the organic acid in the detergent reacts with the neutralizer, which reduces the irritation of the detergent. The neutralizing agent is neutralized, and only a small amount of organic acid plays a cleaning role, resulting in poor cleaning effect. This reduces the irritation of the cleaning agent at the expense of the basic functions of the cleaning agent itself, such as cleaning and sterilization, and is wasted Lots of organic acids. At the same time, the neutralization reaction between the organic acid and the neutralizing agent is essentially an acid-base neutralization reaction, and a large amount of heat is released during the reaction, which is dangerous in production. (3) The organic acid with mild acidity is introduced into the composition of the cleaning agent, but it is often used in combination with other acids with strong acidity, so the irritation of the cleaning agent itself has not been effectively improved; but in order to achieve strong The cleaning effect often increases the addition ratio of mildly acidic organic acids in the detergent ingredients. Due to the excessive increase in the ratio of organic acids, the irritation of the detergent is increased.

Therefore, reducing the irritation of the cleaning agent while making the cleaning agent have efficient soil removal ability has become an urgent problem to be solved in the production of the cleaning agent.

Among them, the remaining components of Comparative Example 1 are the same as those of Example 4, the remaining components of Comparative Example 2 are the same as those of Example 5, the remaining components of Comparative Example 3 are the same as those of Example 6, and the remaining components of Comparative Examples 4-7 are some of the existing commercially available products. detergent.

Based on the above implementations 1-11 and comparative examples 1-7, corresponding detergent samples were prepared respectively, and the prepared detergent samples were subjected to the detergency test and the nasal irritation test.

Among them, the detergency test method is as follows:

(1) Preparation of calcium scale tablets

Take a clean glass slide with a size of 7.5cm*2.5cm, weigh its mass with a balance, and record it as m ₀ ; drop about 2.0g of the calcium scale solution prepared in the laboratory on the glass slide, and then coat the surface. uniform; put it in an oven at 105°C for 24 hours of aging, take it out, and let it stand at room temperature for 2 hours; after the glass slide has returned to room temperature, weigh the mass of the calcium scale and record it as m ₁ .

(2) Decontamination test

Add 200ml of the bathroom scale cleaner stock solution to be tested in a 300ml beaker, completely immerse the part of the above-mentioned glass slide with calcium scale in the solution, time it at the same time, and take it out immediately after 5 minutes; then put the calcium scale sheet into the container After washing in a beaker with clean water for 10 seconds, take it out; put the tested slides in a 105°C oven for 24 hours, take them out, and let them stand at room temperature for 2 hours; after the slides return to room temperature, weigh calcium The mass of the flakes is recorded as m ₂ .

The detergency is expressed by the mass change of the slide at each stage, and the detergency is calculated by the following formula

X=(m ₁ -m ₂ )/(m ₁ -m ₀ )*100%

In the formula: X - detergency;

m ₀ - the net weight of the slide;

m ₁ ——the mass of the glass slide after it is evenly coated with calcium scale and air-dried;

m ₂ ——the mass of the glass slide after the decontamination test has been air-dried;

Note: The above test environment is 25 ℃ room temperature.

The nasal irritation test method is as follows:

(1) The bathroom cleaner stock solution of each comparative example and embodiment that needs to be tested for irritation is placed in a spray bottle with a specification of 500ml; the following operations are carried out beside the laboratory pool: press the pre-pressing spray gun of the bottle with the right hand For 10 seconds, the liquid is sprayed out; the tester's face is close to the pool, the left hand is continuously incited, and the stimulation in the air environment near the pool is felt with the mouth and nose for 10 seconds.

(2) Evaluation method for irritation of nasal mucosa:

A total of 12 male and female volunteers (aged 23 to 45 years old) were selected to conduct a sensory evaluation of the nasal mucosa irritation of the bathroom cleaner, and the detergency effect was evaluated according to the following 5 grades: 10 points, nasal mucosa irritation Very strong; 8 points, relatively strong irritation of the nasal mucosa; 6 points, moderate irritation of the nasal mucosa; 4 points, weak irritation of the nasal mucosa; 0 points, no irritation of the nasal mucosa. The average value of the scores of the 20 volunteers was collected as the evaluation result of nasal mucosa irritation.

The test data in Table 5 and Table 6 are obtained by adopting the above-mentioned detergency test method and nasal irritation test method, wherein Table 5 represents the detergency test of the detergent samples of Examples 1-8 and Comparative Examples 1-4 and nasal irritation test data, Table 6 shows the detergency test and nasal irritation test data of the cleanser samples of Example 9 and Comparative Examples 5-7.

table 5:

Table 6:

2 and 3 are line graphs of detergency and nasal irritation bar graphs of the cleanser samples of Examples 1-8 and Comparative Examples 1-4 drawn according to the test data in Table 5.

From Table 5 and Figure 2, it can be seen that in the detergent samples prepared by using lactic acid as the decontamination acid, the detergency increases with the increase of the acid content. When the acid content is higher than 6%, the detergency always remains at a high level. Weak fluctuations. While the bathroom cleaner prepared with lactic acid as the decontamination acid, when the content of lactic acid is less than 6%, its detergency is slightly weaker than that of the bathroom cleaner prepared with citric acid as the decontamination acid, but when the lactic acid is used as the decontamination acid When the content of citric acid reaches 6%, its detergency is similar to that of the bathroom cleaner using citric acid as the decontamination acid. It can be seen that the bathroom cleaner prepared by using lactic acid as the decontamination acid can also achieve efficient decontamination. Effect. At the same time, it can be seen from FIG. 3 that when the content of lactic acid reaches 6%, the irritation of the cleaning agent is lower than that of the bathroom cleaning agent prepared by using citric acid as the decontamination acid. In addition, when the lactic acid content is 3%, the bathroom cleaner has low irritation, and its stain removal ability can reach about 78%.

It can be seen from Figure 3 that in the detergent samples prepared by using lactic acid as the decontamination acid, with the increase of the amount of lactic acid added, the irritation of the corresponding detergent samples gradually increased, while the bathroom detergent prepared by using citric acid as the decontamination acid Compared with the lactic acid-based bathroom cleaner with the same acid content, the sample has a very close decontamination ability, but the nasal irritation is far more than twice that of the lactic acid-based bathroom cleaner.

Therefore, the preferred lactic acid addition range is 3% to 5%, and the chelating agent addition range is 0.01% to 2%.

As can be seen from Table 6, the detergent sample stock solutions of Comparative Example 5 and Example 9 are acidic and the pH value is relatively close, but the detergent sample stock solution of Example 9 with lactic acid as the decontamination acid shows stronger detergency; The neutral detergent sample stock solution of Comparative Example 6 and the alkaline cleaner sample stock solution of Comparative Example 7 have very poor cleaning ability for calcium scale, far less than the detergent sample stock solution of Example 9. In addition, the nasal irritation of Comparative Examples 5 to 7 is significantly higher than that of Example 9.

To sum up, the embodiment of the present invention provides a bathroom cleaning agent and a preparation method thereof, using lactic acid as the decontamination acid in the cleaning agent. Compared with other organic acids, the lactic acid is milder in acidity and has a lower Therefore, the prepared cleaning agent has low irritation, and at the same time, a chelating agent is introduced into the composition of the cleaning agent, and the chelating agent can effectively complex metal ions such as calcium and magnesium in the dirt, and cooperate with the lactic acid for decontamination. , has a synergistic descaling effect with lactic acid, so that a better descaling effect can be achieved when a smaller amount of lactic acid is used, and the descaling effect of the detergent can be enhanced. On the other hand, the lactic acid used in the ingredients itself has antibacterial properties, which can effectively reduce the addition amount of bactericides in the detergent formulation and save the development cost of detergent products.

The above are only specific embodiments of the present application. It should be pointed out that for those skilled in the art, without departing from the principles of the present application, several improvements and modifications can also be made. It should be regarded as the protection scope of this application.
