Description

Car Window Cleaner Composition

Automotive glass surfaces are always contaminated with oils and waxes used to clean the car body, dust in the air, sand, lead, exhaust gas of automobiles and the like. Particularly, the silicone oil (silcon oil) contained in the fats and oils and waxes flows in part by rain or washing, resulting in a strong adhesive silicone oil film. For this reason, the transparency of the glass surface is remarkably reduced, and the headlights and traffic light beams of the oncoming car are diffusely reflected to blur the field of vision, which is a great risk factor for safe operation. Cleaners are needed to avoid this risk.

Conventional automotive window cleaners contain 0.5 ~ 1.2 wt% of detergent components, tax aids, other protective agents and water, and are packaged in 1.8 liter PET bottles. It causes environmental pollution (waste generation), and wastes resources.

The present inventors conducted a number of studies and experiments to improve the incidence, as a result, the detergent composition is concentrated as much as possible to increase the ability to remove organic pollution than the existing product, and also dilute the product 10 to 40 times the environmental pollution after use ( The present invention was found to be able to greatly reduce the generation of waste) and greatly save resources.

The present invention relates to an automotive window cleaner composition comprising an anionic surfactant, a nonionic surfactant and an organic decontamination agent as a concentrated cleaning component.

In the cleaning composition of the present invention, an anionic surfactant and a nonionic surfactant are used in an approximately 1 to 1 ratio in order to improve the cleaning function, and an organic decontamination agent is mixed and used. If only nonionic surfactants are used, the ability to remove inorganic salts may be impaired. As the anionic surfactant, it is preferable to use 2.0 to 20.0% by weight, preferably 4 to 15% by weight of the linear alkyl anionic surfactant substituted with sulfuric acid. In the cleaning composition of the present invention, the anionic surfactant has 9 to 16 carbon atoms and preferably 1 to 3 sulfuric acid groups. When using anionic surfactant less than 2.0% by weight dilution 10 to 40 times can not be expected to use the cleaning effect, when used more than 20.0% by weight is accompanied by excessive foaming, manufacturing difficulties are involved.

As the nonionic surfactant, 2.0 to 20.0 weight, preferably 4.0 to 15 weight% of the nonionic surfactant substituted with ethylene oxide may be used.

In the present invention, it is preferable to use a nonionic surfactant having 10 to 19 carbon atoms and 5 to 7 ethylene oxide substituted. If the nonionic surfactant is used in an amount of 2.0 wt% or less, the cleaning power is reduced by diluting 10 to 40 times, and in the case of using 20.0 wt% or more, bubbles are generated due to high viscosity, which leads to difficulty in manufacturing.

The organic decontamination agent in the cleaning composition of the present invention uses 3-methoxy-3-methyl-1-butanol or dipropylene glycol-n-butyl ether. These organic decontamination agents are less affected by temperature and are very colorless solvents with good solubility in water.

In the cleaning composition of the present invention, the solvent of 3-methoxy-3-methyl-1-butanol or dipropylene glycol-n-butyl ether is preferably used in an amount of 10.0 to 40.0 wt%. When the organic pollution remover is diluted 10 to 40 times to 10.0 wt% or less, the effect of removing organic pollution is weak, and when used more than 40 wt%, no further effect can be expected and economical.

Automotive window glass cleaner compositions of the present invention may further contain preservatives, chelating agents, ethyl alcohol, dyes and flavors.

Anticorrosive agents are added because they may cause corrosion of the car body due to the cleaning agent. Corrosion inhibitors are used in amounts of 0.1 to 3.0% by weight, for example benzoic acid or sodium silicate. When the dilution agent is diluted 10 to 40 times by 0.1 wt% or less, the effect is weak, and when more than 3.0 wt% is used, no further effect can be expected.

A chelating agent that collects ions present in water is used in an amount of 0.2 to 5.0 wt%.

As the chelating agent, tetraacetic acid-4 sodium dimethyl or 2 sodium dimethyl (EDTA-4Na, EDTAO-2Na) or the like is used. When the chelating agent is diluted 10 to 40 times by 0.2 wt% or less, the effect is insignificant, and when 5.0 wt% or more is used, it appears to be unnecessary.

Ethyl alcohol is used in an amount of 15.0 to 40% by weight for low temperature stability. When used below 15.0% by weight of ethyl alcohol, the stability is lower than below 10 ° C, and when used above 40.0% by weight, it is not economical due to excessive use.

Appropriate amounts of dyes and flavors are used as other auxiliaries, with weight percent being water.

Hereinafter, although this invention is demonstrated concretely based on an Example, the technical scope of this invention is not limited to these.

Examples and Comparative Examples

Table 1 is for cleaning power evaluation test, Table 2 is for environmental pollution test, the following components are sequentially added to the water and stirred thoroughly to prepare a vehicle window glass cleaner.

TABLE 1

TABLE 2

The following tests were performed on the Example and Comparative Example cleaning composition shown in Table 1 and Table 2.

1) Detergency Test

8 to 10 grams (g) of artificial pollutant on a glass surface 2 x 6 cm are evenly applied on toilet paper. A glass surface coated with an artificial pollutant is placed at a 45 ° angle, and the composition liquid diluted 10 times for Examples 1, 3, and Comparative Example 1, and 20 times for Examples 2, 4, and 2 is used for general household use. After spraying 5-7 ml once with a spray-type sprayer, rub lightly twice with a pressure of 1 kg / cm 2 using an automotive wire and visually discriminate. Artificial pollutants are manufactured in accordance with the Korean Industrial Standard KS M 2742 automotive flow inhibitors.

2) Test for environmental pollution (waste generation)

180 mL of Example 5, 90 mL of Example 6, 45 mL of Example 7, 45 mL of Example 7, and 1,800 mL of Comparative Example 3 were respectively injected into a 1.8 L PET bottle, and the residue was filled with water. 1.8 liter PET bottle consumption was tested for Examples 5, 6, 7 and Comparative Example 3 based on the consumption of a 1.8 liter bottle of cleaning solution prepared in Example 3 after injecting into an actual vehicle washer liquid tank (1.8 liters). .

The test results are shown in Table 3.

TABLE 3

As a result of the evaluation by the above method, the cleaning composition of Examples 1, 2, 3, and 4 was better in the test for artificial contamination cleaning than the cleaning compositions of Comparative Examples 1 and 2, but the composition of Comparative Examples 1 and 2 was organic. The cleaning power was weak due to no decontaminant. On the other hand, in the case of Comparative Example 3, 36 bottles, 38 bottles than Example 5, 39 bottles compared to Example 6, and 39 bottles of 1.8 L PET bottles were consumed more, and it was not efficient in resource utilization.

As described above, the window glass cleaner composition of the present invention was found to reduce environmental pollution (waste generation) while having an excellent cleaning ability.
