Description

Cosmetic composition for preventing fine dust

The present invention relates to a cosmetic composition for preventing fine dust, and more particularly to a fine dust adhesion preventing cosmetic composition having excellent antifouling effect and UV protection effect by using a polymer network having a hydrophobic strengthening function and amphoteric ions. .

Women's instinct for beauty is not yesterday's work, but recently, there is a growing interest in body care, beauty, or cosmetics to make herself look more beautiful.

And as women, as well as women, are interested in cosmetics for skin care, the cosmetics market continues to expand, and various kinds of cosmetics are on the market.

Generally, cosmetics can be broadly divided into basic cosmetics, makeup bases and color cosmetics, and are manufactured in solid, liquid or gel cosmetics, and various cosmetic containers for storing them are also applied.

Recently, functional cosmetics that can perform various functions such as moisturizing, whitening, wrinkle improvement, sun protection, acne relief, atopy relief, anti-inflammatory or keratin lysis have been widely consumed.

On the other hand, the skin is an organ located at the outermost shell and is the organ most exposed to various harmful environments such as fine dust and ultraviolet rays. Many studies have reported that chronic fine dust exposure is a major cause of aging and pigmentation. In addition, as the damage caused by fine dust has become an issue, various cosmetic products for blocking fine dust have been released.

Fine dust usually carries PAH (polyaromatic hydrocarbons). Fine dust coated with polycyclic aromatic hydrocarbons with high lipophilic and skin penetrating ability combines with arylhydroarbon receptor (AHR) in keratinocytes and melanocytes to promote the expression of pro-inflammatory mediators Causes

In addition, ROS (active oxygen) production is increased due to the penetration of PM (particulated matter) into the skin. Ozone (O ₃ ) is a very unstable molecule that attacks the skin, causing lipid peroxidation and protein oxidation.

The combination of UVA and polycyclic aromatic hydrocarbons causes visible photo-damage on the skin. PAHs have also been shown to cause significant amounts of photo-pollution stress due to light reactivity and phototoxicity. Therefore, chronic exposure to ultraviolet rays and fine dust can accelerate visible skin damage.

The most focused efficacy in the cosmetics industry in recent years is the protection of the skin against ultraviolet rays and various contaminants. In order to achieve this, various polymer network formulations are being developed that function to protect the skin from harmful environments such as fine dust, and thus are related to cosmetic compositions to which ion repulsion technology is applied in connection with fine dust or ultra fine dust.

Table 2 shows the specific composition according to an embodiment of the present invention. First, distilled water may be applied as a solvent. Carbomer is used as a water soluble thickener and can be 2.5 to 5% by weight. 5% by weight is recommended for the stability of the formulation as it is difficult to form emulsification above.

The amount of 1,3-Butylene glycol is 0.5 ~ 15% by weight is appropriate, but less than 0.5% by weight is less moisturizing effect, if more than 15% by weight may affect the formulation stability.

The sunscreen may be made from about 10 to 50% by weight, and when it is 10% by weight or less, the sunscreen effect is insignificant, and when it is 50% by weight or more, the texture is heavy and tends to break down the formulation stability.

Sodium Hydroxide is used as a pH adjuster and the appropriate amount in the formulation can be 0.1 to 5% by weight.

Identify hydrophobicity enhancement

In order to confirm the hydrophobicity improvement ability of the fine dust anti-fouling cosmetic composition according to an embodiment of the present invention was prepared by comparing a control that does not contain DP MC.

The composition and the ratio of the control group are shown in Table 3. The contact angle to confirm the hydrophobicity enhancement ability was measured as follows. Samples (1.28 mg / cm 2) were applied to PMMA HD6 plates. Initial contact angles were measured with a KRUSS DROP SAHPE analyzer (Model DSA30). Contact angles were calculated based on Young's equation. Thereafter, the plate was immersed in purified water and the contact angle of the sample when measured with water was measured after 30 seconds.

test item	Control	DP MC-containing formulation
Initial contact angle	64.21	50.73
Contact angle after water exposure	75.88	83.35

As shown in Table 4, as a result of measuring the contact angle before and after exposure to water, it was observed that the contact angle of the formulation containing DP MC improved by 64.3% compared to before exposure to water. Through this, it can be seen that the hydrophobicity is increased upon contact with water.

Check the effect of fine dust adhesion prevention

Clinical tests were conducted to observe the anti-dust adhesion effect of the samples. Subjects were selected to meet 20 criteria and applied to forearm. In order to make the measurement conditions of the subjects the same, the test site was kept clean and dry and proceeded after the skin was stabilized at a place where constant temperature and humidity (22 ± 2 ° C, R.H. 40-60%) was maintained for at least 30 minutes.

The test product was applied to the selected test site (3 cm × 3 cm) of the forearm in an amount of 2 μl / cm 2 using a micro pipette. After application was dried in a constant temperature and humidity space for 15 minutes after immersion according to the product usage. After drying, the selected test site was fixed in the fine dust floating chamber, and then pseudo-fine dust was uniformly sprayed in the appropriate amount chamber. After the injection, the similar fine dust remaining on the test site was analyzed. The similar fine dust was carbon black (MITSUBISHI MA220, JAPAN).

Images for residual dust analysis were taken using a high-resolution digital camera (CANON EOS 50D, JAPAN) under the same conditions of the same brightness of the room lighting. Was worn.

The analysis of the similar fine dust remaining after exposing the similar fine dust to the test site was performed by using an image analysis program (Image-Pro plus). .

Table 5 shows the results of analysis of the residual pseudo-fine dust at the coated and uncoated areas using the image analysis program.

Finally, the rate of improvement of adhesion prevention of residual similar fine dust can be obtained by comparing the amount of application site and the amount of uncoated site. The improvement rate formula is shown in Equation 1.

The improvement rate was calculated using the improvement rate formula and compared with the non-coating part of each subject, and the results are shown in Table 7.

Improvement rate compared to uncoated area (Unit:%)

As shown in Table 7, as a result of the measurement, the improvement rate of anti-adhesion of similar fine dust was measured as 72.9% of subjects in DP MC and the average of 39.7% in control. That is, it can be confirmed that the fine dust protective effect of the fine dust adhesion prevention cosmetic composition according to an embodiment of the present invention is more excellent.

In particular, it can be confirmed that the fine dust adhesion prevention improvement effect is excellent compared to the case of the non-coating (Fig. 5) and the control product (Fig. 4).

	Fine particulate matter Before impressions	Fine particulate matter After exposure	Fine dust Prevention effect
Test product application (before exposure to water)	11.3	28.3	34.61%
Test product application (after exposure to water)	11.3	16.0	81.93%
No coating	13.0	39.0	Control
