Description

[0001] The present invention relates to a cosmetic composition for underwater type macro emulsion,

The present invention relates to a cosmetic composition for underwater type macro emulsion ultraviolet shielding.

The market for sunscreen agents is growing rapidly. In addition, the regulations on PA marking, which is the UVA blocking index, have been implemented from PA +++ to PA ++++ in January 2013, and Korea and China have been in operation since December 2016. In general, UVA is a light ray having a long wavelength of about 320 to 400 nm, which is known to reach a dermal layer with a low energy but high transparency. Taichi, M et al. Fragrance Journal, 43, p31, 2015. Studies on the transmission of UVA wavelengths through glass windows have been carried out.

Some organic UV and inorganic sunscreens can be used as raw materials to prevent UVA. However, in the case of an organic UV-blocking agent capable of blocking the UVA region, it is difficult to apply the PA +++ + formulation due to the problem that the excessive amount can not be applied to the formulation due to the precipitation problem in the water-in-silicone formulation.

As a water drop type cosmetic, for example, No. 2014-0062695 discloses a macro emulsion cosmetic composition of a silicone water (W / S) type. The cosmetic composition is based on a non-liquefiable silicone elastomer, which is about 13% oily (including silicone oil) and is difficult to apply to SPF 50 + PA +++ + formulations by the above method and is difficult to apply to underwater type formulations using salts Disadvantages and traumas are silicone oil, which has good water resistance but heavy feeling.

Accordingly, the inventors of the present invention have conducted research on the development of ultraviolet screening cosmetics which are water-in-water type (O / W) having a light use feeling to improve the problem of such ultraviolet screening agents but also have excellent water resistance.

2. Test Example

2.1 Emulsion particle observation

The particle size and the emulsified state of Examples 1 and 2 and Comparative Examples 1, 2 and 3 were observed using an optical microscope (OLYMPUS BX53PH). In the case of Example 1, as shown in Fig. 1, formation of a macroemulsion of 2.0 to 5.0 mu m was observed, and water bursting was observed upon application of the skin.

In Example 2, in which a water-soluble thickener was added in a large amount, water rupture phenomenon was observed to be small. Stable particles were observed as shown in Fig. 2, but more stable particle formation was observed as a microemulsion rather than a macroemulsion.

On the other hand, in Comparative Example 1 in which the general emulsification system was applied, general emulsified particles were formed as shown in Fig. In the case of Comparative Example 2 in which the solubilizing agent was applied, uniform microparticles were produced as shown in FIG. 4, but ordinary microemulsions were produced.

2.2 Formulation stability test

The viscosity changes and the pH changes were carried out at 25 ° C, 4 ° C and 50 ° C for each of the days 1, 2, and 1, 2, and 3, Respectively.

As can be seen from Table 2, it was confirmed that the stable formulation was formed under both long-term stability and severe conditions in Examples 1 and 2 and Comparative Examples 1, 2 and 3 of the present invention. It is confirmed that the emulsion system of Examples 1 and 2 applied in the present invention has stability similar to Comparative Example 1 in which an emulsifier is applied and Comparative Example 2 in which a solubilizer is applied.

On the other hand, in the general emulsification type (Comparative Example 3) in which a water-based thickener, a usual emulsifier or a solubilizing agent was not applied, the viscosity was gradually lowered and separation phenomenon was observed within one month. Through this study, it was confirmed that the emulsifier had little or no emulsifying power, but the aqueous thickener was effective for particle formation and safety.

On the other hand, Comparative Example 1, which is a general emulsification type, is the same ultraviolet blocking main component. No water resistance was observed.

2.6 Sensory evaluation

Thirty women aged 25-45 years were divided into two groups, and Examples 1 and 2 and Comparative Examples 1 and 2 were appropriately adjusted to each group to be used on both sides of the face. Then, according to the following evaluation criteria, The sensation of feeling such as stickiness, adhesion, makeup picker ability, and overall satisfaction was evaluated, and the results are shown in Table 6 below.

The above-mentioned rubbing property refers to a feeling of being absorbed into the skin when the skin is first applied to the skin, and a lightly applied feeling is a cosmetic suitable for a suncare cosmetic. The residual feeling is a feeling of use due to the oil and wax remaining on the skin due to the unique characteristics of the sunscreen after application to the skin, and the less the residual feeling, the more suitable for the ultraviolet screening cosmetic. The freshness is the ultraviolet barrier cosmetic which is excellent in fresh feeling after absorption and low in viscosity and light form. These criteria increase the value of cosmetics and can be an important feature of cosmetics with ultraviolet blocking properties.

As shown in Table 6, Example 1 was satisfactory overall, and Example 2 was also superior in terms of spreadability, residual feeling, and freshness. On the other hand, Comparative Examples 1 and 2 showed a tendency that feeling of use and overall satisfaction were lower than those of the products manufactured by the method of the present invention.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It belongs to the scope of right.
