Manufacturing example  1: Preparation of 50% Ethanol Extract of Gosam

Dried ginseng, which is commercially available, was purchased and prepared as a powder using a pulverizer. To 20 g of the prepared powder sample, 300 mL of 50% ethanol was added as an extraction solvent, and the mixture was added to a stirrer (Heidolph, specifications: MR 3001, MR 3001K) and stirred at 300 rpm for 3 hours. The extract solution was collected by filtration using a filter paper, and then the filtrate was concentrated under reduced pressure at 45 ° C using a concentrator (Heidolph, LABOROTA 4000) to prepare a 50% ethanol extract of Gossam.

Manufacturing example  2: Gosam's Heat number  Preparation of extract

Dried ginseng, which is commercially available, was purchased and prepared as a powder using a pulverizer. To 20 g of the prepared powder sample, 1 L of distilled water was added to a potter (manufacturer: Daewoong, Standard: DWP-3000M) and extracted for 60 minutes. The extract solution was recovered by filtration using a filter paper, and the filtrate was concentrated under reduced pressure at 45 ° C using a concentrator (Heidolph, LABOROTA 4000) to prepare a hot-water extract of red ginseng.

Experimental Example  1: Bubble strength test

In the case of the surfactant component, the surface tension of the water is lowered to easily foam in an aqueous solution. Therefore, the measurement of the bubble force is an indicator for visually confirming the surface activity capability.

The bubble strength test was carried out in the following manner.

(KS M 2709), 200 ml of the solution was dropped from the height of 1200 mm at a room temperature for 20 seconds, and the height thereof was measured in mm units immediately after bubbles were generated. For the positive control group, a mixture of four surfactants (Micopol LDE / Micolin T430 / Micolin ES 430 / Mitaine CA) was used at a concentration of 0.1%. For the experimental group, 1% concentration of the extract was used.

The bubble strength test results are shown in Table 1. As shown in the following Table 1, the extracts of gosam prepared in Preparation Examples 1 and 2 of the present invention were found to have similar degree of bubble formation as compared with the positive control.

Experimental Example  2: Cleaning power test

Cleaning is the process by which the surfactant is adsorbed by the contaminants and separates the contaminants. The detergency is a major factor for determining the surfactant activity, and it can be judged that the detergent surfactant is a good surfactant.

The detergency test was carried out in the following manner.

Pollutants were prepared from the contents of Table 2 below, 0.05 ml was uniformly applied to the glass specimens, and then dried at room temperature for 12 hours. 30 ml of distilled water and 50 ml of distilled water were mixed with 10 ml of a mixture of four kinds of synthetic surfactants (Micopol LDE / Micolin T430 / Micolin ES 430 / Mitaine CA) and 50 ml of distilled water and 50% One piece of the contaminated glass specimen was washed with a platform shaker for 3 minutes and then dried at room temperature for 12 hours in a container containing 10 ml of the hot water extract of Preparation Example 2. The amount of residual oil red (Sudan III) was determined by measuring the absorbance of the remaining oil dross (Sudan Ⅲ) in 5 mL of tetrachloroethylene and measuring the absorbance of the absorbent (manufacturer: Bio-tek KONTRON INSTRUMENTS, spec. UVIKON923) The wavelength of the peak point was selected after measuring the propagation field. The measured absorbance was converted into the washing power by the following formula (1).

The amount of applied oil red is the absorbance of a mixed solution of 0.05 ml of the contaminant and 5 ml of tetrachlorethylene, and the residual amount is the absorbance of the contaminant remaining after washing and the mixed solution of 5 ml of tetrachlorethylene.

Composition component Condition Palmitic acid Oleic acid Colorant (Means III) chloroform The hardness of the water to be used 1g 9g 0.05 g 30 mL 50 ppm

The results of the detergency test are shown in Table 3 below. As the amount of residual contaminants is confirmed by the absorbance, it can be seen that the lower the absorbance, the smaller the amount of contaminants remaining and the better the detergency is. As shown in the following Table 3, it was confirmed that the hot water extract of Gosam prepared in Preparation Example 2 of the present invention exhibited similar cleaning power as that of the positive control group.

Experimental Example  3: Dispersibility  Test

Dispersion is a phenomenon in which the dispersibility is greatly changed by the addition of a surfactant to a suspension or emulsion, which causes aggregation or stabilization. This dispersion effect is due to the strong adsorption property of the surfactant, which decreases the interfacial energy and reduces the thermodynamic instability of the system . Therefore, for the adsorption test of the surfactant, the absorbance was measured using a light absorber (manufacturer: Bio-tek KONTRON INSTRUMENTS, standard: UVIKON923) after addition of red Fe ₂ O ₃ .

The dispersibility test was carried out in the following manner.

First, 0.15 g of Fe ₂ O ₃ was added to a beaker of Tween 60 and 50 ml of an extraction sample, and the mixture was stirred at 500 rpm for 20 minutes using a stirrer (Heidolph, standard: MR 3001) to uniformly disperse Fe ₂ O ₃ . The dispersed solution was placed in a fraction funnel, 2 ml of the suspension was taken from the bottom of 20 ml, diluted with 100 ml of distilled water, and absorbance was measured at 705 nm.

The results of the dispersity test are shown in Table 4 below. Since the experiment confirms the degree of dispersion of Fe ₂ O ₃ , the higher the absorbance, the better the dispersibility. As shown in the following Table 4, it was confirmed that the extracts of gosam prepared in Production Examples 1 and 2 of the present invention had similar dispersing powers to Tween 60, which is a positive control group.

Experimental Example  4: Emulsifying activity  Test

The emulsifying activity indicates the affinity between the surfactant and the selected oil as the substrate, which is an important factor for directly confirming the surfactant activity.

The emulsification activity test was carried out in the following manner.

2 ml of the measurement solution was mixed with 2 ml of 0.2 M phosphate buffer (pH 7), each of the substrates was placed in a 1 ml tube and stirred vigorously for 1 minute using a vortex mixer (Heidolph, manufacturer: Reax top) The emulsion was emulsified and allowed to stand for 10 minutes, and the suspension was measured at 540 nm using a light absorber (manufacturer: Bio-tek KONTRON INSTRUMENTS, spec. UVIKON 923).

The results of the emulsification activity test are shown in Table 5 below. As the experiment to confirm the degree of emulsification of the substrate and the measurement sample, the higher the absorbance, the better the substrate and the emulsifying activity. As shown in Table 5, although the emulsifying activity was different according to the extraction method of the ginseng extract, the extract of the ginseng prepared in Preparation Examples 1 and 2 of the present invention showed good emulsifying activity in most of the substrates.

Experimental Example  5: Emulsion stability test

Emulsion stability refers to the emulsifier's ability to stabilize emulsions after formation of emulsions or under conditions such as mixing, high temperature, and centrifugation.

The emulsion stability test was carried out in the following manner.

The suspension was allowed to stand at room temperature for 1 hour, 2 hours, and 3 hours after the treatment in the same manner as in the measurement of the emulsifying activity, and the degree of suspension at 540 nm was measured.

The results of the emulsion stability test are shown in the following Table 6 and Figs. 1 and 2. As shown in the following Table 6 and Figs. 1 and 2, the extracts prepared in Production Examples 1 and 2 of the present invention have emulsion stability In all of the five substrates.
