Description

[0001] Sunscreen cosmetic composition of mousse type [0002]

More particularly, the present invention relates to a mousse-type ultraviolet screening composition which has a high ultraviolet barrier property and is light in use, is formulated into a mousse form, easy to be repeatedly used, convenient for application to a wide area, And to a cosmetic composition for ultraviolet ray shielding.

The cosmetic composition of the mousse form has a feature that the contents are sprayed in the form of foam to spread easily on a large area of the skin as well as on the face, and the application feeling is light, so that it is easy to apply and easy to use repeatedly when applied to an ultraviolet screening product. However, due to the nature of the mousse formulation, the surfactant, which is essential for prescription, is weak and weak in water and sweat, so the feeling of use is light and can be repeatedly used. Despite the advantage of being able to spread easily over a wide area, And it has limitations in use for leisure and sports.

Therefore, due to such a problem, the product development is not so much developed as compared with the cream or lotion type sunscreen of the mousse type.

<Manufacturing Method>

The organic ultraviolet screening agent and the oil phase components are dissolved at a composition ratio shown in Table 1 at 80 캜. A mixture of the organic ultraviolet screening agent and the oil phase component is slowly added to a mixture of all the aqueous phase components at room temperature, followed by stirring. Then, the remaining additives are added to prepare an oil-in-water type (O / W) emulsion, and then filled in the can as emulsion: LPG (composition ratio propane: butane = 30: 70 wt%) = 90:10 wt%.

[Test Example 1] Measurement of ultraviolet blocking index (SPF) and ultraviolet A blocking degree (PA)

The ultraviolet barrier index was determined by attaching a transparent plastic tape (Transpore Tape; 3M, USA) to a prepared cast according to the 'Ultraviolet barrier function test method' of the 'functional cosmetics standards and test methods' 4 and Comparative Examples 1 and 2 were coated with a sample of 2 mg / cm ² , and the ultraviolet blocking effect was measured by a UV detector (SPF 290 Analyzer). In addition, the measurement of the ultraviolet A cutoff grade PA was performed using a multi-port solar simulator 601-300W (Solar Light, USA) equipped with a 300W xenon arc lamp as a light source and a 3D UV meter The light intensity was measured using a Solar Light (USA), and the ultraviolet A cutoff grade PA was measured for the compositions of Examples 1 to 5 and Comparative Examples 1 and 2. The results are shown in Table 2 below. &Lt; tb &gt;&lt; TABLE &gt;

Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Comparative Example 2 SPF 52.8 ± 2.3 52.5 ± 3.4 51.5 ± 3.6 50.6 ± 3.5 49.6 ± 2.5 45.6 ± 2.5 52.4 ± 3.7 PA +++ +++ +++ +++ +++ ++ +++

As can be seen from the values shown in the above Table 2, the SPF index and the PA grade were both high in the Example according to the present invention and Comparative Example 2 using the surfactant, but in the case of Comparative Example 1 in which no wax was used, It can be confirmed that the composition of the present invention does not satisfy the criteria to be provided. Also, in the case of Example 5 using only one type of thickening agent, the PA grade was high but the SPF index was slightly lower than the SPF 50.

[Test Example 2] Measurement of bubble forming force

In order to measure the foam forming ability of the composition, the emulsion was filled in a can of LPG (composition ratio propane: butane = 30: 70 wt%) = 90: 10 wt% Were evaluated as good, normal, and defective. If the bubbles were maintained for more than 3 minutes after discharge, it was evaluated as good. If the bubbles were maintained for 30 seconds or more and less than 3 minutes, it was evaluated as poor. The results are shown in Table 3 below.

Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Comparative Example 2 Bubble formation Good Good usually usually Bad Bad Good

In the results shown in Table 3, in Example 5 using only one thickener and Comparative Example 1 without wax, Examples 3 and 4, in which the foaming ability was poor and wax was present but one increment was lost, Lt; RTI ID = 0.0 &gt; 1 &lt; / RTI &gt; In Comparative Example 1, which is a general cream type containing a surfactant, the foaming power was good.

[Test Example 3] Water resistance effect

The water resistance was determined by repeatedly submerging the sunscreen-treated skin (water resistance: 2 times for 20 minutes and 4 times for 20 minutes of continuous water resistance) according to the Guidelines for Measurement of Waterproof UV Protection (COLIPA Guideline 2005.12) . After calculating the water resistance ratio of each subject compared with the ultraviolet barrier index of the non-immersed skin, the water resistance (or the lasting water resistance) was determined when the unilateral 90% confidence interval calculated by the average value of 10 or more was 50% or more of the average value. The results are shown in Table 4 below.

Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Comparative Example 2 Water resistance O O O O X X X

From the results in Table 4, it can be seen that Example 5 having only one increment, Comparative Example 1 having no wax, and Comparative Example 2 having a surfactant have no water resistance.

[Test Example 4]

The overall satisfaction of the compositions of Examples 1 to 5 and Comparative Examples 1 and 2 was evaluated by 30 women aged 25 to 45 years, such as foam-forming ability, spreading, stickiness, and shine. The formulations of Examples 1 to 5 and Comparative Examples 1 and 2 were applied to the face area of the face immediately by hand and the results are shown in Table 5 below.

Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Comparative Example 2 Feeling (satisfaction) 5 5 4 4 3 3 5

(Evaluation Criteria) Very poor: 1 / poor: 2 / normal: 3 / good: 4 / very good: 5

From the results shown in the above Table 5, the feeling of use feeling was low in Example 5 having only one incrementer and Comparative Example 1 having no wax, and Examples 3 and 4 in which one incrementer was missing were also shown in Examples 1 and 2 It can be confirmed that the satisfaction level is lower than that.

As can be seen from the results of Test Examples 1 to 4 above, the present invention can be applied to pickling formulations free of surfactants by controlling the wax and thickener to make a mousse form, It can be used not only for living UV rays but also for outdoor and leisure activities while retaining the lightness and coolness of the existing Moose type. In addition, the moose-type ultraviolet barrier cosmetic composition of the present invention can be variously modified and implemented, and all the modified embodiments should be interpreted as being included in the scope of the present invention unless departing from the scope of the present invention.
