Description

TECHNICAL FIELD [0001] The present invention relates to a cosmetic composition for blocking fine dust,

The present invention relates to a cosmetic composition for blocking fine dusts.

Particulate matter (PM) or dust is an air pollutant that contains harmful substances such as sulfur dioxide, nitrogen oxides, heavy metals, ozone, and carbon monoxide. It occurs in automobiles and factories, Which means long-term floating material. The fine dust is indicated as PM 10 when the particle size is 10 μm or less, and is referred to as "ultrafine dust" or "ultrafine dust" when the particle size of the fine dust is 2.5 μm or less. Technically, it is called aerosol. Further, the fine dust is also called suspended particles, particulate matter, and the like, and has a slightly different meaning depending on the name. The aerodynamic particle size (diameter) of the particulate matter is about 10 nm to 100 탆. When the particle size is larger than this, the residence time in the atmosphere is very short due to the sedimentation effect due to gravity.

These fine dusts penetrate into the body not only through the nose, mouth, but also through the skin. The skin of the human body is largely composed of a skin layer and a dermal layer. The skin layer forms a barrier (skin barrier) as if the bricks are piled tightly, and prevents penetration of dust or the like into the body. However, fine dust containing heavy metals and environmental hormones break down these skin barriers and penetrate the body. The fine dust containing the toxic chemical causes contact with the skin to cause cell deformation, which causes cracks in the skin barrier, so that various carcinogens and environmental hormones contained in the fine dust easily penetrate the human body . The size of the human pore is 2 to 5 times larger than the fine dust size (about 0.01 mm), so that the pores can easily pass through.

These fine dusts are a major cause of various skin diseases. At first, it can worsen atopic dermatitis and acne. The reason is that the harmful substances contained in the fine dust promote the secretion of inflammatory cytokines from the cells and increase the leukocytes and cause the allergic reaction. Domestic studies have shown that children with atopic dermatitis worsen on the day when the concentration of outdoor fine dust is high, and the symptoms of atopic dermatitis are alleviated when the indoor fine dust level is lowered.

In addition, such fine dusts also exacerbate itching and dryness. Because fine dust weakens skin metabolism and lowers sebum control function. The waste matter in the skin is not removed properly, causing trouble, and the fat balance of the skin surface may be broken, resulting in drying and itching. In addition, fine dust promotes skin aging. Absorbed fine dust stimulates the pigment cells of the skin, causing blotches and wrinkles. A follow-up study of 400 adult women over a 24-year period found that women living next to roads with high air pollution had about 22% more pigmentation and wrinkles in their faces than women living in rural areas . Accordingly, functional cosmetics for protecting the surface of the skin from being easily infiltrated into the skin have been studied.

Centella asiatica is a small herbaceous plant belonging to the wild dwarf ( Umbelliferae ) at 600 to 800 meters above sea level, which is a tropical dwarf area and is at the most ideal altitude. The extracts of the clover have been used as traditional medicines in India, Asia Africa and Madagascar and have been used for the healing of skin and mucous membrane diseases. The Western medical practitioners said that the anti-inflammatory, skin regeneration and healing properties of the seedlings originated from the molecule belonging to the triterpene series, and the madecassoside, asiaticoside, asicicide, Asiatic acid and madecassic acid compounds were found to have excellent skin regeneration and healing efficacy. These four active compounds promote anti-inflammatory action and collagen synthesis to protect cells from inflammatory stress and promote skin regeneration.

division Maskless mask Example 1 [0050] Dust collection efficiency (%) 98.34 99.49

Referring to the results of Table 5, it was found that the dust collecting efficiency of the mask was increased when applying the embodiment of the present invention, and the fine dust blocking effect of the cosmetic composition of the present invention was excellent.

Experimental Example  5: Measurement of breathability

The cosmetic composition according to the present invention forms a double protective film in the form of a film when applied on the skin surface in order to block fine dusts. If the double protective film does not have air permeability, it can lead to skin troubles by blocking pores. Therefore, when the cosmetic composition of the present invention was applied to the skin, a confirmation test was conducted to determine whether or not it had air permeability. The measurement method is the same as that of Example 1, except that the air permeability of the nonwoven fabric is compared with that of the nonwoven fabric, and the results are shown in Table 6 below. The air permeability was measured by the Frazier method, and the velocity of the air passing vertically through the specimen under the specified pressure and time was measured. The amount of air flowing vertically through a certain area of the cloth was constant The pressure difference for the test area of the fabric was calculated over time.

division Mud pouch Example 1 Air permeability (Frazier method) (mm / s) 648 120.9

Referring to Table 6, although the air permeability of the fabric coated with the Example 1 of the present invention was lower than that of the nonwoven fabric, the air permeability value was present, indicating that the fabric had air permeability. This shows that the double protective film formed upon application of the cosmetic composition of the present invention does not greatly affect the breathability.

Experimental Example  6: Antioxidant power measurement

In order to measure the antioxidant activity of the cosmetic composition according to the present invention, the free radical scavenging rate using DPPH was measured. DPPH was diluted with methanol to a concentration of 10 mM. The experimental material was diluted with DW to the concentration of Example 1 (final concentration: 0, 1, 5, 10, 50, 100%). 100 μl of the sample according to the concentration of Example 1 and 100 μl of the DPPH solution were added to the 96-well plate in that order, followed by reaction at 37 ° C for 30 minutes. After the reaction, the absorbance was measured at 517 nm using a microplate reader. DW was used instead of the sample as a blank, and compared with trolox (0.13%) as a positive control. The results are shown in FIG.

Referring to FIG. 4, analysis of free radical scavenging ability using DPPH showed that Example 1 exhibited a significant free radical scavenging activity in a concentration-dependent manner.

Experimental Example  7: Measurement of collagen production effect

In order to measure the collagen production ability of the cosmetic composition according to the present invention, HDFs (Human Dermal Fibroblasts) were inoculated on 24-well plates at 5 × 10 ⁴ cells / well and cultured for 24 hours. 0, 0.00125, 0.0025, 0.005, 0.01%), and cultured for 24 hours. After incubation for 24 hours, the supernatant was taken and the amount of procollagen liberated in the medium was measured at 450 nm using Procollagen Type I C-Peptide (PIP) ELISA KIT. The degree of collagen production was evaluated by calibrating with the total protein amount, and the result was compared using L-ascorbate as a positive control. The results are shown in FIG.

Referring to FIG. 5, it can be seen that Example 1 significantly increased intracellular collagen production.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
