Abstract

The present invention relates to a spray-type cosmetic composition comprising an oleic acid ester-based emulsifier having hydrophile-lipophile balance (HLB) of 1 to 9. The composition may have a wide spray angle and a fine and uniform particle size.

Description

[0001] The present invention relates to a spray type cosmetic composition comprising oleic acid ester type emulsifier,

The present invention relates to a spray-type cosmetic composition comprising an oleic acid-based emulsifier.

Spray-type cosmetics can be sprayed directly onto the skin by pressure of the spraying container or the spraying agent of the pressure-tightly sealed container without hand-taking or application by a separate tool. Cosmetics are sprayed in the form of fine particles, and moisture, moisturizing ingredients, and other cosmetic ingredients can be immediately supplied to the skin. Therefore, they are used in skin care products, sunscreen agents, make-up products and the like.

When the particles of the cosmetic material sprayed onto the skin are large or coagulated, the sprayed cosmetic material may flow down or it may be necessary to separately spread the cosmetic material with a hand or a tool. Therefore, it is preferable that the spray-type cosmetic material has a small particle size, a uniform spray distribution, and a wide spray angle.

Therefore, research for fine and uniform distribution of cosmetics like fog has been continued.

The prior art of this specification is disclosed in Korean Patent Laid-Open Publication No. 10-2007-0113552.

In view of the above, a problem to be solved by the present invention is to provide a spray-type cosmetic composition in which the size of particles sprayed at the time of spraying is minute and uniform.

In another aspect, a problem to be solved by the present invention is to provide a spray-type cosmetic composition having a wide spray angle.

In another aspect, a problem to be solved by the present invention is to provide a spray-type cosmetic composition that imparts instantaneous moisturizing power to skin through mist spraying.

In one aspect, the present invention relates to a spray-type cosmetic composition comprising an oleic acid ester emulsifier having 1 to 9 HLB (Hydrophile-Lipophile Balance).

In one aspect, the present invention can provide a spray-type cosmetic composition in which the size of particles injected at the time of injection is minute and uniform.

In another aspect, the present invention can provide a spray-type cosmetic composition having a wide spray angle.

In another aspect, the present invention can provide a spray-type cosmetic composition that imparts instantaneous moisturizing power to the skin through mist spraying.

(1) Spray angle: As shown in FIG. 1, the injection angle of Example 1 and Comparative Example 1 was measured with a high-speed camera and the spray angle from the discharge port was measured, and the results are shown in Table 2.

(2) Injection pattern: In order to confirm the spray pattern, a black aqueous pigment was added in an appropriate amount to the composition according to the above Examples and Comparative Examples. A white paper was placed on the surface 30 cm away from the container in parallel to the container, and the pattern was visually confirmed. The results are shown in FIG. 2 and Table 3.

(3) Spray pattern analysis: The spray pattern of the above (2) was analyzed using a particle size analyzer (Spraytec, STP5311, Malvern Korea) and shown in FIG. 3 to FIG. 8 and Table 4. D10 means particle size at 10% of total particle size, D50 means particle size at 50%, D90 means particle size at 90%, and Span means (D90-D10) / D50 that the particle size distribution It is a value indicating how far it is spread. The smaller the value of the span, the more uniform the size of the particles.
