Description

   Blend with sunscreen cosmetic with porous powder        [Related application]    

This application claims the priority of Japanese Patent Application No. 2017-087937 filed on April 27, 2017, and the contents are incorporated herein by reference.

The present invention relates to a sunscreen cosmetic formulated with a porous powder.

Generally speaking, it is known that a cosmetic material prepared with a lipophilic porous powder can absorb the sebum secreted from the skin over time, thereby suppressing the generation of stickiness and maintaining a dry feeling. In addition, it is also known that the spherical lipophilic porous powder exerts an effect (for example, a pore-modifying effect) of making the unevenness on the skin visually insignificant by adjusting its refractive index.

Due to such advantages, a large amount of lipophilic porous powder is formulated in powder cosmetics, and for other types of cosmetics, it is also an ingredient that is expected to be formulated in large quantities. Since it is lipophilic, it is often blended in the oil phase. However, by adding a specific polymer to the surface, a technology for dispersing in the water phase has also been developed (Patent Document 1).

The cosmetic material using the water phase as the continuous phase exhibits a refreshing feeling of use, and is therefore particularly suitable for cosmetics used in summer (such as sunscreen cosmetics). However, since the ultraviolet absorbent is usually oil-soluble, if the ultraviolet absorbent is blended in a cosmetic material containing a lipophilic porous powder in an aqueous phase, the ultraviolet absorbent will be absorbed by the powder and the effect of preventing ultraviolet rays cannot be exhibited. The problem.

This phenomenon is not limited to the ultraviolet absorber, but is a problem that the oil-soluble functional components are common to the whole.

Therefore, a technique for stably dispersing the aforementioned lipophilic porous powder having excellent characteristics and the functional component soluble in oil in the aqueous phase is required.

FIG. 1 is a graph showing absorption spectra of coating films composed of the cosmetic materials of Test Examples 2 and 3.

Hereinafter, preferred embodiments of the present invention will be described. In this specification, "powder" and "powder" are synonymous.

[Test Example 1]

The cosmetics of the formula of the following Table 1 were manufactured by the said method, and the evaluation result with respect to the said evaluation item is shown in Table 1. In a steady state (after standing for 1 day at 20 ° C and 1 atmosphere), Test Examples 1 and 2 are one layer, and Test Examples 3 and 4 are separated into oil-in-water emulsified particles containing ultraviolet absorbers. Three layers of an upper layer, a lower layer containing a porous powder, and an intermediate layer composed of other components. Therefore, in the above-mentioned functional test, the cosmetic materials of Test Examples 3 and 4 were suspended in a container containing these materials to form a layer, and then applied.

The compounds in the table are as follows.

＊ 1: PRESS-AID SP (made by PRESPERSE)

＊ 2: Techpolymer MBP-8HP (spherical, manufactured by Sekisui Chemical Industry Co., Ltd.)

＊ 3: Sunsphere L-51s (spherical, manufactured by AGC Si-Tech Co., Ltd.)

＊ 4: PEMULEN TR-2 (manufactured by BFGoodrich)

＊ 5: SIMULGEL NS (SEPPIC)

＊ 6: KELTROL (manufactured by Kelco)

＊ 7: PPG-1000 (Sanyo Chemical Industry Co., Ltd.)

＊ 8: SACHTLEBEN RC-402P (made by SACHTLEBEN PIGMENTS OY)

As shown in Table 1, an acrylic acid ‧ alkyl methacrylate copolymer containing a crosslinked polymethyl methacrylate powder as a lipophilic porous powder and an acrylic polymer as a polymer dispersant (( Acrylic ester / alkyl acrylate (C10-30)) crosslinked polymer), and the cosmetic of Test Example 1 in an aqueous medium and containing no ultraviolet absorber, the lipophilic porous powder was well dispersed in the aqueous phase , The continuous effect of dry feeling and the effect of pore modification are excellent, but the UV protection effect cannot be obtained. The cosmetic of Test Example 2 equipped with a UV absorber was blended with this cosmetic (while slightly changing the composition of the oil content). Although a slight ultraviolet shielding effect was seen, the pore modification effect and the continuous effect of dryness were impaired. the result of. This is presumably because the lipophilic porous powder absorbs the ultraviolet absorber, changes the refractive index of the powder, and prevents the absorption of sebum by the powder.

On the other hand, regarding the cosmetic material of Test Example 3 in which the ultraviolet absorbent was formulated in the oil-in-water emulsified particles, the oil-in-water emulsified particles and the lipophilic porous powder system were dispersed in the water phase. Excellent UV protection effect, continuous dry feeling effect, and pore modification effect. However, when the porous body of the cosmetic material of Test Example 3 was replaced with a hydrophilic porous silica cosmetic material (Test Example 4), the result of impaired pore modification effect was obtained.

In addition, the coating film composed of the cosmetic material of Test Example 3 has a higher absorbance in the ultraviolet region than the coating film composed of the cosmetic material of Test Example 2 and exhibits an excellent ultraviolet shielding effect (Fig. 1).

According to this, if the ultraviolet absorber is directly formulated in a system in which the lipophilic porous powder is dispersed in an aqueous medium by the polymer dispersant, the pore modification effect and dryness caused by the lipophilic porous powder are dry. The sustained effect is impaired, and the UV protection effect is not fully exhibited (compared with Test Examples 1 and 2). If the ultraviolet absorber is formulated in the state of oil-type emulsified particles contained in water, the lipophilic porosity will not be damaged The above-mentioned effect of the fine powder and the ultraviolet shielding effect can be fully exhibited (Test Example 3).

Hereinafter, formulation examples of various cosmetics prepared with the oil-in-water emulsified composition according to the present invention will be listed, but the present invention is not limited to these.

Formulation example 1: beauty liquid

Formulation Example 2: Beauty Solution

Formulation Example 3: Beauty Liquid

Formulation example 4: daytime lotion

Formulation example 5: daytime lotion

Formulation example 6: daytime lotion
