Description

A composition for sunscreen containing bamboo extract as an active ingredient {Sunscreen composition containing Bambusa vulgaris extract as active ingredient}

The examples below relate to compositions for sunscreen.

Ultraviolet rays can cause freckles or blemishes by promoting the formation of erythema or the production of melanin pigment within skin cells, and can cause skin problems by reacting with sebum secreted from the epidermis to produce lipid peroxide. In severe cases, it can cause skin cancer. You can also do it. Ultraviolet rays are shorter than the violet part of visible light and are called UV (ultraviolet). Depending on their wavelength, they are divided into UVA (320-400 nm), UVB (280-320 nm), and UVC (100-280 nm). UVA (ultraviolet A) not only turns the skin red, but also acts on the skin's immune system and can cause long-term skin damage due to skin aging. UVB (ultraviolet B) rays can burn the skin and penetrate skin tissue, sometimes causing skin cancer.

There are two types of sunscreens used to prevent skin damage caused by ultraviolet rays: organic sunscreens and inorganic sunscreens. Organic sunscreens precipitate during long-term storage and have low stability, making them difficult to use in large quantities, making them difficult to provide high UV protection effects. Accordingly, conventional sunscreen cosmetic compositions contain a large amount of inorganic sunscreen to provide a high sunblock effect, but they have a sticky residue on the skin and a wet feel, making consumers feel uncomfortable when using them.

Accordingly, the present inventors completed the present invention as a result of conducting research on a sunscreen that provides an excellent feeling of use while exhibiting an ultraviolet ray effect.

At this time, the concentration of the bamboo extract is 0.15 ppm.

Meanwhile, Comparative Examples 1 and 2 were prepared in the same manner as the above Example. However, Comparative Example 1, unlike the Example, did not contain bamboo extract, carrot extract, and potato extract, and Comparative Example 2 contained niacinamide, carrot extract, bamboo extract, potato extract, palmitic acid, stearic acid, adenosine, and nitric acid. Does not contain stick acid or tocopherol.

[Experimental Example] Evaluation of UV blocking ability and usability

The ultraviolet ray blocking ability and usability of the prepared Examples and Comparative Examples 1 and 2 were evaluated by the following methods.

Method for evaluating UV protection ability

The ultraviolet UVA blocking test was conducted according to the test method presented in the Japan Cosmetic Association's UVA blocking effect measurement method (JCIA, 2012). This test method uses the International Organization for Standardization's UVA blocking effect measurement method (ISO24442, 2011). The cosmetic compositions of the standard sample, Examples, and Comparative Examples 1 and 2 were uniformly applied to the subject's back in an amount of 2 mg/cm ² and stabilized for 15 minutes, then irradiated with ultraviolet A based on the uncoated MPPDD. The MPPDD and PFA of the standard sample, Example, and Comparative Examples 1 and 2 were determined. The minimum continuous immediate darkening amount (MPPDD) was determined, and using the determined value, the UV A blocking index was calculated using Equation 1 below, and the average value was obtained. Ultraviolet A protection levels are classified as shown in Table 1 below.

[Equation 1]

PFA calculation method = Minimum continuous instantaneous blackening amount (MPPDp) on the area where the sample was applied / Minimum continuous immediate blackening amount on the area where the sample was not applied (MPPDu)

Usability evaluation method

30 women in their 20s to 40s were asked to apply makeup for 5 days using the cosmetic compositions of the above Example and Comparative Examples 1 and 2. Then, through a survey, stickiness and adhesion were assessed on a 5-point scale (very high stickiness: 1 point, high: 2 points, average: 3 points, low: 4 points, very low: 5 points) The scores were evaluated according to the scale (low: 1 point, low: 2 points, normal: 3 points, high: 4 points, very high: 5 points) and the average value was calculated.

The results of measuring ultraviolet ray blocking ability and usability using the above method are shown in Table 2 below.
