<Experimental Example> Evaluation of the physical properties of the detergent composition

(1) Leather cleaning performance evaluation

In order to evaluate the cleaning performance on the leather of the cleaning composition prepared by the method according to the example, the cleaning power of the cleaning composition was evaluated according to the KS M 3709 (1991) test method, and the results are shown in Table 2 below. .

To evaluate the cleaning performance, a mixture of 20 parts by weight of tallow, 3 parts by weight of a red dye (Solvent Red 27), 5 parts by weight of glycerin monostearate, and 72 parts by weight of acetone was added dropwise to the surface of the leather specimen, followed by 30 minutes. A stained leather specimen was prepared by leaving it to stand, and the cleaning composition was applied to the prepared leather specimen and then rubbed 30 times or more. The degree of thinning was evaluated by a 9-point evaluation method, and the lower the value, the better the cleaning state.

As a result of evaluating the cleaning performance of the cleaning composition on the leather, as shown in Table 2, all of the leather specimens washed by applying the cleaning composition prepared by the method according to the example showed significantly lighter color of contaminants than the control. performance was confirmed.

As a result of evaluating the change in gloss of the leather by the cleaning composition, as shown in Table 2, all the leather specimens coated with the cleaning composition prepared by the method according to the example showed improved gloss compared to the control, thereby improving the appearance of the leather. It was confirmed that it could be improved.

In particular, as can be seen in Examples 2 and 4, it was confirmed that the gloss was further improved due to the addition of the papaya fruit extract, and the ingredients such as enzymes contained in the papaya fruit extract were homogeneous in the leather. It was determined that the glossiness was further improved by forming one surface.

(5) Antimicrobial evaluation

The antibacterial properties of the cleaning composition prepared by the method according to the example were evaluated, and the results are shown in Table 3 below. Antimicrobial evaluation was performed by applying a detergent composition to a culture dish in which Staphylococcus aureus (S. aureus ) and E. coli were cultured at the same concentration, respectively, and measuring the reduction rate of bacteria after 24 hours.

As shown in Table 3, it was confirmed that the cleaning compositions prepared by the method according to Examples 1 and 2 all exhibited excellent antibacterial effects against Staphylococcus aureus and E. coli, and in particular, the method according to Example 2 It was confirmed that the antibacterial performance was further improved by additionally including a papaya fruit extract.
