Description

Spray cosmetic composition containing emulsifier based on oleate

This manual is about a spray-type cosmetic composition with oleate-based emulsifier.

A spray cosmetic is a product that can be sprayed directly on the skin and used by the pressure of the spray container or the propellant in the spray container, without removing part of the product with the user’s hand or using a separate tool to apply part of the product process. Because cosmetics can be sprayed in the form of fine particles to immediately replenish moisture, moisturizing ingredients and other beauty ingredients to the skin, the spray-on cosmetics are used in skin care products, sunscreens, makeup products, etc.

When the particles of the cosmetics to be sprayed on the skin are large in nature or the sprayed cosmetics form clumps, the sprayed cosmetics may flow down or may need to be applied separately and applied to the skin with hands or tools. Accordingly, the fine particles to be sprayed in the preferred spray-on cosmetics are small in size, uniform in particle distribution, and wide in spray angle.

In this regard, research on spraying fine and uniform cosmetics (such as mist) has been steadily ongoing.

The related technology of this specification is described in Korean Patent Application Publication No. 10-2007-0113552 A.

[ Physical Property Evaluation ]

The following physical properties are evaluated using the mist composition of the examples and comparative examples.

(1) 噴塗角度：如圖1所示，當實施例1及比較實施例1之組成物被噴塗的時候，以高速攝影機拍攝用以測量該組成物由釋出埠噴出之噴塗角度，結果如表2所示。 (2) 噴塗模式：該組成物係在實施例及比較實施例之組成物中含有適當量之水性黑色著色料來製備，用以確認其噴塗模式。將一白紙置於與容器平行且距離30 cm遠之面上，以肉眼確認其噴塗模式，結果如圖2及表3所示。 (3) 噴塗模式分析：使用粒徑分析儀(Spraytec, STP5311, Malvern Instruments Ltd., Korea)分析(2)之噴塗模式，如圖3至8及表4所示。D10、D50及D90意指整個顆粒大小中分別為10%、50%(中位數)及90%之粒徑，該跨度(Span)係以(D90 – D10)/D50算出且係代表粒徑分佈(particle size distribution)分散情況之值。跨度值很小意指顆粒大小均勻集中。 表3

表4

由結果可確認，相較於比較實施例，實施例之噴塗角度顯著寬廣、噴塗範圍廣泛分佈且噴塗顆粒均勻且細小。可看出在比較實施例1至3中噴塗之顆粒尺寸大且分佈也不均勻，而在比較實施例4中噴塗之顆粒因為其為尺寸大而聚集。[ 實施例 1 之配方 ] 霧狀配方 霧狀配方係被製備如下表5之組成物。 表5

The physical properties were evaluated by the following method: the mist composition of the example and the comparative example was sealed in the container described in Table 2 below, and the mist was sprayed with one end of the container vertical to the ground Composition. Table 2

(1) Spraying angle: As shown in Figure 1, when the composition of Example 1 and Comparative Example 1 is sprayed, take a high-speed camera to measure the spraying angle of the composition from the discharge port. The results are as follows Table 2 shows. (2) Spray mode: The composition is prepared by containing an appropriate amount of water-based black coloring material in the composition of the examples and comparative examples to confirm the spray mode. Place a piece of white paper on the surface parallel to the container and 30 cm away, and confirm the spray pattern with the naked eye. The results are shown in Figure 2 and Table 3. (3) Spraying mode analysis: Use particle size analyzer (Spraytec, STP5311, Malvern Instruments Ltd., Korea) to analyze the spraying mode of (2), as shown in Figures 3 to 8 and Table 4. D10, D50 and D90 refer to the particle size of 10%, 50% (median) and 90% of the entire particle size, respectively. The span (Span) is calculated by (D90-D10)/D50 and represents the particle size Distribution (particle size distribution) the value of dispersion. A small span value means that the particle size is uniformly concentrated. table 3

It can be confirmed from the results that, compared with the comparative example, the spraying angle of the embodiment is significantly wider, the spraying range is widely distributed, and the spraying particles are uniform and fine. It can be seen that the sprayed particles in Comparative Examples 1 to 3 are large in size and unevenly distributed, while in Comparative Example 4, the sprayed particles are aggregated because of their large size.
