Description

COSMETIC COMPOSITION FOR SKIN MOISTURIZER [0002]

Disclosed herein is a cosmetic composition for skin moisturizing which has improved moisturizing power and moisturizing duration.

Human skin is the primary shield that protects the human body from various stimuli derived from the external environment. In addition, it is also a barrier to prevent the body's moisture, which is absolutely necessary to maintain bioactivity, from escaping to the outside. The human body is inevitably exposed to a relatively dry environment compared to the skin, and thus the skin, especially the stratum corneum, has a variety of substances that store moisture and prevent evaporation, and thus play a very important role in maintaining moisture in the body. Two of the most important factors for the moisturizing function of the stratum corneum are the intercellular lamellar lipids acting as a film to prevent water evaporation and the other as decomposition products of filaggrin in keratinocytes The natural moisturizing factor is responsible for holding moisture in the stratum corneum.

In the case of various skin diseases or aged skin, the function of these two main factors deteriorates and the moisturizing condition of the skin deteriorates, so that dryness can easily occur. In this case, dryness can relieve pruritus or other dermatosis caused by dryness. It can be a means. In addition, the moisture in the stratum corneum helps to maintain the activity of enzymes having various physiological activities, and thus can maintain the skin barrier in a healthy state. Therefore, the moisturizing agent is required not only for skin having dryness but also for maintaining healthy skin Can play a role.

Polyhydric alcohols, water-soluble polymers, organic acid salts and the like are generally used as moisturizers contained in cosmetics. Occlusive ingredients that prevent oil from evaporating on the surface of the skin, which are oily with a moisturizing agent, A method of increasing moisture retention in the stratum corneum by using a humectant having a property is widely used. However, the conventional moisturizing agent exhibits a temporary effect, and when applied, can exhibit a moisturizing effect for a short time, but has a problem that the skin moisturizing effect can not be continuously maintained for a long time.

Example  One.

A sample of a cosmetic composition was prepared according to a conventional method according to the compounding ratio shown in Table 1 below.

Specifically, the raw material of the water phase was placed in the auxiliary emulsification tank, heated to 75 DEG C to dissolve it, and then transferred to the main emulsification tank. Then, the raw material of the oil phase was placed in the auxiliary emulsification tank, and the mixture was heated to 75 DEG C to dissolve it, and emulsified (HOMO 3000 rpm, PAD 30 rpm, 10 minutes) while being transferred to the main emulsification tank. After emulsification, the mixture was cooled and defoamed to 45 ° C., and plant extracts were added at 45 ° C. and mixed uniformly. The fragrance was added at 40 캜 under constant cooling, uniformly mixed, and cooled to 30 캜 to prepare a cosmetic composition sample.

Experimental Example  1. Evaluation of skin moisturizing and moisturizing sustainability efficacy

Twenty-one subjects in the 20s to 40s of adult women who did not meet the exclusion criteria, including those with sensitivity and irritable skin, who met the selection criteria, were selected and assigned to the test site and the control site, In the forearm of the test region, the cosmetic composition sample prepared in Example 1 was applied at a dose of 2 mg / cm ² once, and no action was taken on the forearm of the control region.

After application, conditions and environments that could affect the test results were blocked to assess the moisturizing sustainability of the composition according to the present specification. Specifically, during the initial 6 hours, the subjects stayed in the waiting room where the conditions of the constant temperature and humidity were maintained, returned home after 6 hours, and prohibited all actions that could irritate the test site for 101 hours or affect the test results. Skin moisturizing and moisturizing durability was evaluated with a moisture analyzer (corneometer ^® CM-825, Courage & Khazaka, Germany) at 1 hour, 3 hours, 6 hours, 24 hours, 48 hours, 72 hours, 96 hours, And the water content in the stratum corneum was measured. Moisture content was measured 5 times each, and the average value was determined for 3 measurements excluding the maximum value and the minimum value. The statistical significance of the test site and control site measurements was analyzed and verified using the Mann-Whitney nonparametric test of the SPSS program (version 19.0.0), and the improvement in moisture retention (%) was derived from the following equation.

Table 4. Numerical variation and moisture improvement rate by moisture meter by time zone

As a result of obtaining valid data without dropping out of the 21 subjects, the composition according to the present invention showed a skin moisturizing effect lasting more than 107 hours at a statistically significant level (p <0.05) as compared with the control site without the sample Respectively.

That is, there was no difference in the water content in the stratum corneum at the measurement sites on both sides of the skin before application, but it was found that the moisture content of the test site was significantly higher from 1 hour after application, and this moisturizing effect was maintained for a long time . Specifically, the moisture improvement rate showed a maximum value of 101.13% after 3 hours of application, and a significant improvement in moisture retention of 21.79% even after 107 hours of application, and it was confirmed that the stability was maintained without abrupt decrease even after 107 hours.

Experimental Example  2. Evaluation of side effects

During the course of Experimental Example 1, adverse effects related to the use of the samples were classified as mild, moderate, and severe, with or without erythema, edema, scab formation, itching, sore throat, burning sensation, stiffness, tingling, No abnormal symptoms were found.

Example  2 and Comparative Example  1 to 5.

A sample of the cosmetic composition was prepared in the same manner as in Example 1, and a sample of the cosmetic composition was prepared according to the compounding ratio shown in Table 5 below.

Table 5. Formulation ratio (%, w / w)

Experimental Example  3. Evaluation of skin moisturizing and moisturizing sustainability efficacy

The skin moisturizing and moisturizing endurance efficacy of the cosmetic composition prepared in Example 2 and Comparative Examples 1 to 5 was evaluated in the same manner as in Experimental Example 1, and 18 subjects of 20 to 50 adult women with dry skin type Were randomly selected into 6 groups of 3 persons, and each cosmetic composition sample was applied to the forearm of the subject once at a dose of 2 mg / cm ² . Skin moisture and moisture persistence efficacy was measured by the moisture content of the stratum corneum using a moisture analyzer (corneometer ^® CM-825, Courage & Khazaka, Germany) at 1 hour, 6 hours, 24 hours and 72 hours before and after application.
