Description

Cosmetic composition and cosmetic comprising frame nanoparticles having a porous structure

[0001] The present invention relates to a cosmetic composition in which an active ingredient is well absorbed into the skin, skin moisturizing power is excellent, skin troubles are improved, and skin texture is excellent. More specifically, the invention relates to a cosmetic composition and a cosmetic product comprising frame nanoparticles having a porous structure inside.

[0002] Currently, nanotechnology is being applied to the cosmetics industry in various forms. For example, 'nano-liposomes' are a type of capsule used to deliver beauty ingredients deep into the skin and are utilized in functional cosmetics such as anti-wrinkle, whitening, and sunscreens. These capsules are known to maximize their effectiveness by penetrating the stratum corneum of the skin, as they are very small, measuring approximately 10 nm in size.

[0003] In addition, nano-sized titanium dioxide (TiO₂) and zinc oxide (ZnO) particles are used in sunscreens to effectively reflect or scatter ultraviolet rays, and these nano particles are known to improve spreadability and reduce white cast, thereby improving consumer satisfaction.

[0004] Meanwhile, the frame nanoparticle of the present invention is a type of nanolens, and a nanolens acts as a lens that enables imaging and optical control through the ultrafine manipulation of light. Although both nanoparticles and nanolenses are based on nanotechnology, they differ in that their goals and functions are completely different.

[0005] As such, nanotechnology plays an important role in improving the efficacy and user experience of cosmetics, but there are no specific examples of nanolenses being used in the cosmetics field yet.

[0006] In this regard, Korean registered patent No. 10-2497161 discloses a method for synthesizing frame nanoparticles having a porous structure and a surface-enhanced Raman scattering analysis method using the same, but there is no example of applying this to a cosmetic composition or cosmetic product.

[0007] Meanwhile, cosmetic products containing gold have recently been appearing, and Korean Public Patent No. 10-2004-0026472 discloses a method for manufacturing cosmetics with added gold powder. The invention uses gold processed to within 2000 μm, and the cosmetic is characterized by being used for ingestion and application to the skin. While the cosmetic according to the invention has the advantage of being convenient to use, it is ineffective for skin moisturization and absorption. Furthermore, conventional commercially available cosmetics containing gold powder have aesthetic advantages such as improving skin tone and making the skin clean and transparent, but their effects on skin absorption and moisturization are weak.

[0008] In addition, Korean published patent No. 10-2006-0089903 discloses a cosmetic composition in which a useful ingredient is stabilized within an interfacial multi-liquid crystal formed by a complex of a Gemini-type surfactant having two hydrophilic groups and two hydrophobic groups simultaneously in one molecule, which is completely different from the structure of conventional surfactants, a higher alcohol, an auxiliary emulsifier, ceramide, cholesterol, etc. However, the interfacial multi-liquid crystal has a large particle size of about 1.0 to 3.0 μm in the shape of four petals, which is a problem, and thus the skin penetration effect is poor.

[0009] Accordingly, the inventors confirmed that a cosmetic composition fused with frame nanoparticles having an internal porous structure exhibits excellent skin condition improvement and intracellular penetration effects, and thus completed the present invention.
