CLEANSING COMPOSITION AND MANUFACTURING METHOD THEREOF FIELD OF THE INVENTION [0001]

The present invention relates to a cleaning composition and a method of manufacturing the same, and more particularly, to a cleaning composition having a water-based form capable of washing without requiring any water-based finishing anytime and anywhere, and a method of manufacturing the same.

With rapid modernization, many cars have been introduced into the country, and it is known that there are currently more than 20 million vehicles in operation in Korea. Such automobiles have been washed, coated, and polished in various ways for the purpose of protection and aesthetics of paint films of automobiles.

Generally, washing means removing contaminants and the like on the exterior of a vehicle through a step of applying foam to the vehicle and removing bubbles using water. In addition, in order to polish when necessary, it takes a lot of time, labor and cost because it is subjected to a process of coating and polishing using a polishing agent, a coating agent or a wax, and the like.

More specifically, in order to wash the vehicle, a large amount of water is used to remove the pollutants, and then the detergent is used. Then, the detergent is rinsed with water, and then the water is removed from the mop and dried. That is, 1) the pollutants are firstly removed by using water on the outside of the vehicle, 2) an appropriate amount of detergent is sprayed on the exterior of the vehicle, 3) the pollutants are removed first, 2) the detergent is mixed to produce foam, the contaminants that have not been removed with water are removed, and 4) water is finally used to remove foam and contaminants in step 3).

In this process, a large amount of water is used in steps 1) and 4). In general, since the amount of water to wash a vehicle is about 100 liters to 200 liters, none.

As described in Korean Patent No. 0473528, a cleaning agent using natural materials has been developed. However, the cleaning agent is deteriorated, and water is required to be used as a means for removing the cleaning agent as the cleaning agent is used.

Accordingly, it is urgent to develop a cleaning composition that exhibits excellent cleaning power as in the conventional cleaning agent, and can be cleaned only by applying a cleaning agent without using water and then wiping it.

The present invention relates to cleaning compositions and processes for their preparation.

Example  3

Evaluation of gloss increase

3 g of celite which was diluted with 10 wt% of water, which was 0.8 mm in width, 75 mm in width and 155 mm in height, was sampled on the abrasive paper and rubbed so that the gloss of the steel sheet fell to 60. After polishing, the remaining celite was thoroughly washed with water and fused, and then completely dried to prepare a specimen. Initial glossiness was measured on the specimens prepared as described above, about 1 g of the cleaning composition of Production Examples 1 to 9 and Comparative Examples 1 to 5 was applied to the entire steel sheet, and then coated with dedicated microfiber, and then water was sprayed for 5 seconds The degree of gloss increase was measured immediately after washing.

Gloss increase Production Example 1 19 Production Example 2 16 Production Example 3 13 Production Example 4 20 Production Example 5 20 Production Example 6 18 Production Example 7 19 Production Example 8 18 Production Example 9 19 Comparative Example 1 14 Comparative Example 2 7 Comparative Example 3 12 Comparative Example 4 14 Comparative Example 5 14

As shown in Table 3, all of the cleaning compositions of Production Examples 1 to 9 exhibited gloss increases of about 20 GU except Production Example 3, while in Comparative Examples 1 to 5, the cleaning compositions of 7, 12 and 14 GU It was confirmed that the degree of luster of the cleaning composition of the present invention was excellent in view of the fact that the degree of luster was measured.

Example  4

Coefficient of friction measurement

A steel plate with a thickness of 0.6 mm, a width of 50 mm, a length of 50 mm, and a weight of 700 g was used. The EVA film was attached to the surface to be bonded with the friction material. The friction material sheet was 0.8 mm thick, 75 mm wide, 155 mm in height was prepared by washing with ethanol. After the washed specimens were initially measured at a distance of 60 mm at a speed of 150 mm / min, a friction coefficient was measured, and about 1 g of the cleaning compositions of Production Examples 1 to 9 and Comparative Examples 1 to 6 was applied to the entire steel sheet, And then the coefficient of friction was measured to record the rate of decrease in the coefficient of friction.

Friction coefficient reduction rate Production Example 1 40 Production Example 2 32 Production Example 3 41 Production Example 4 46 Production Example 5 44 Production Example 6 36 Production Example 7 38 Production Example 8 40 Production Example 9 40 Comparative Example 1 19 Comparative Example 2 14 Comparative Example 3 21 Comparative Example 4 16 Comparative Example 5 29 Comparative Example 6 37

The results of measuring the friction coefficient reduction rate are shown in Table 4 above. The cleaning compositions of Preparation Examples 1 to 9 exhibited a frictional coefficient reduction ratio of generally from the late 30's to mid 40's while the Comparative Examples 1 to 6 showed a lower value of generally less than 20 except for Comparative Example 6 Respectively.

In view of the above results, when the polydimethylsiloxane emulsion, the amine-modified polydimethylsiloxane emulsion, the alkyl-modified polydimethylsiloxane emulsion and the MQ silicone resin emulsion are not used as the silicone oil, the rate of decrease of the friction coefficient will be lowered.

The coefficient of friction reduction allows the surface to be smoothened to remove easily when cleaning the surface with dust. Accordingly, when the friction reduction rate is high, scratches can be minimized by the brushes, towels, and other consumables used in the vehicle to which the dust is applied at the time of washing.

In the present invention, the silicone oil affects the reduction of the coefficient of friction, and more specifically, an alkyl-modified silicone emulsion is typical. It was confirmed that the mixing and blending of the raw materials had a major influence on the reduction rate of friction on the coating surface. Comparing Comparative Example 5 and Comparative Example 2, the friction reduction rate was increased by 10% depending on whether the alkyl-modified silicone was prescribed In view of the excellent friction reduction rate in Production Examples 3 to 5 in accordance with the change of the alkyl-modified silicone content, when the optimum content of the alkyl-modified silicone emulsion is in the range of 0.01 to 1.0% by weight, .

In order to evaluate the cleaning power of the cleaning compositions of Production Examples 1 to 9 and Comparative Example 6, the initial color difference values L, a, and b values were measured using a JIS composite contaminated cloth JIS E124 (Carbon black / squalene / oleic acid). A 1L glass beaker was used for the evaluation of detergency, and after the contamination was added to the 600ml product solution, stirring was carried out at 250rpm for 20 minutes. Then, the detergency was calculated using the difference in L, a and b values Respectively.

<Cleaning power formula>

Whiteness = 100 -

Cleaning power (%) = (Whiteness after washing - Whiteness of coloring) / (Whiteness of unipolar - Whiteness before washing) X 100

The whiteness of the temple is 90.

Cleaning power (%) Production Example 1 14 Production Example 2 14 Production Example 3 14 Production Example 4 14 Production Example 5 14 Production Example 6 15 Production Example 7 16 Production Example 8 14 Production Example 9 16 Comparative Example 6 6

According to Table 5 above, the cleaning compositions of Preparation Examples 1 to 9 were measured at 14% to 16%, while the cleaning compositions of Comparative Example 6 were measured at 6%.

As a result, in Comparative Example 6, only water was used without containing a volatile solvent, and thus the aqueous cleaning composition using only water would have poor cleaning ability. In Production Examples 7 to 9, as a result of measuring the cleaning power by varying the content of the volatile solvent, it was confirmed that there was no significant change in the cleaning power. In view of the fact that the volatile solvent in the cleaning composition is 1-8 wt% , It will not have a great influence on the washing power.
