Antibacterial and deodorant cosmetic composition containing Pinus thunbergii extract as an active ingredient}

The present invention relates to a deodorizing and antibacterial cosmetic composition containing a gomsol extract as an active ingredient, and more specifically, to a deodorant and It relates to an antibacterial cosmetic composition.

In general, body odor comes from fat, protein, sebum, and pollutants contained in sweat secreted from eccrine sweat glands distributed throughout the body and apocrine sweat glands distributed in areas with a lot of body hair such as armpits. It occurs in the process of being decomposed by microorganisms or bacteria residing on the skin, and has different odors and triggers depending on the body part. is indicating

In particular, excessive sweat and sebum secretion due to strenuous exercise or stress, and protein and fat secretion along with sweat from eating greasy and oily food are the causes of severe body odor. Caffeine-rich coffee, chocolate, cola, alcohol that increases protein and fat in the body, and smoking, which in itself has a pleasant smell, can also cause unpleasant body odors.

As a method of controlling body odor, various methods are being used, such as the invention of deodorization by an adsorption component, a masking method that blocks body odor using fragrance, and a method of removing deodorization by reacting a deodorant with a body odor component. There are other advantages.

Hereinafter, the present invention will be described in more detail through <Examples> and <Test Examples>.

<Example 1>

The dried gomsol powder was finely divided by a grinder, and then, 70% by weight of ethanol was added in an amount about three times that of the raw material, immersed while stirring for 24 hours, leached, and filtered to obtain an extract.

The extract was concentrated under reduced pressure at 40° C. using a concentrator (R-100, BUCHI) to prepare a Gomsol extract.

<Test Example 1> Deodorization efficacy evaluation

The ability to remove (deodorize) odor components was tested as follows using the Gomsol extract prepared in <Example 1> as a sample at a room temperature of 22° C. and a relative humidity of 45% using the gas detector tube method.

Ammonia is injected into the 3ℓ Tedler bag and measured with a gas detector so that the inner concentration becomes 100 μg/ml, and this is used as the initial concentration. did.

The gas concentration at the initial, 0.5 hour, 1 hour, 1.5 hour, and 2 hours elapsed time was accurately measured with a gas detector. Without injecting the Gomsol extract sample, the same test was used as a blank test, and the test results are shown in [Table 1] and [Fig. 1] below.

division Deodorization rate (%): gas detection tube method 30 minutes passed 60 minutes elapsed 90 minutes passed 120 minutes elapsed Example 1 more than 99 more than 99 more than 99 more than 99

As shown in [Table 1] and the attached [Fig. 1], the Gomsol extract showed high gas removal ability after 0.5 hours, and from this, it can be confirmed that the Gomsol extract has excellent deodorizing effect.

<Test Example 2> Antimicrobial activity evaluation

Antimicrobial activity was evaluated by measuring the minimum inhibitory concentration (MIC) against the skin flora using the two fold-dilution method.

As the test strain, Staphylococcus aureus (ATCC 6538) and Staphylococcus epidermidis (ATCC 12228) were used for the test.

In the MIC measurement method, the concentration of the sample was 1,000 ppm, and 100 μl of the medium containing the sample was added while diluting twice, and then, the concentration of the bacterial suspension was adjusted and 100 μl was added. After culturing at 37° C. for 24 hours, the minimum concentration at which the growth of bacteria does not appear was confirmed, and the results are shown in [Table 2] below.

division Concentration of sample: % (v/v) S. aureus (Staphylococcus aureus) S. epidermidis (Staphylococcus epidermidis) Example 1 0.781 1.562

As shown in [Table 2], it can be seen that the Gomsol extract has an antibacterial effect at 0.781% in Staphylococcus aureus and 1.562% in Staphylococcus epidermis, and from this, the cosmetic composition containing the Gomsol extract according to the present invention is sweaty. It can be predicted that can effectively suppress the specific sampling caused by

<Example 2>

Using the Gomsol extract prepared in <Example 1> as an active ingredient, a softening lotion type cosmetic was prepared according to the composition ingredients and ratios shown in [Table 3] below.

composition Composition ratio (wt%) Gomsol Extract 6 ethanol 6 Polyoxyethylene hydrogenated castor oil 1.0 methyl paraoxybenzoate 2 glycerin 5.0 1,3-butylene glycol 6.0 Spices appropriate amount Purified water To 100

<Test Example 3>

In order to evaluate the degree of skin irritation for the softening lotion type cosmetics of <Example 2>, a patch test was performed on the human body as follows.

Apply 25 μl of each sample to the back of 30 healthy adult males and females, remove the pin chamber after 24 hours, and check the skin condition visually after 30 minutes, 24 hours, and 48 hours have elapsed. 4], and the results are shown in [Table 5] below.

sign Criteria - negative non-irritant ± Doubtful or slight and erythema unstimulated + Erythena + induration mild stimulation ++ Erythema + induration + vesicle central stimulus +++ Erythema + induration + bullae strong stimulus

sample 30 minutes after application
reading 24 hours after application
reading 48 hours after application
reading Average Judgment - ± - ± - ± Example 2 30 people - 30 people - 30 people - 0.00 non-irritant

As shown in [Table 5], it was confirmed that the cosmetic containing the Gomsol extract of the present invention as an active ingredient had very low skin irritation.
