Description

Technology Field

[0001] The present invention relates to a water-soluble patch with a multilayer structure comprising collagen and a blue light blocking component, which dissolves immediately upon spraying a mist to simultaneously block UVA, UVB, and blue light. Furthermore, the present invention includes a dissolution mechanism controllable at specific temperatures and humidity levels, and includes a function that provides a continuous protective effect. Background Technology

[0002] Existing UV protection products (sunscreens, sun sticks, sun sprays, etc.) had limitations in terms of ease of use and uniformity of effectiveness. Furthermore, while the need for blue light protection has increased due to the growing use of digital devices, there has been a shortage of products capable of effectively blocking blue light simultaneously, in addition to UVA and UVB.

[0003] This invention applies technology differentiated from existing products, designed so that a water-soluble patch that dissolves immediately upon spraying mist can effectively block blue light and ultraviolet rays. Furthermore, it is designed to utilize the chemical interaction between the patch and the mist to enable the release of active ingredients at a constant rate after attachment to the skin.

[0019] In addition, the present invention can provide a patch that solves the disadvantages of conventional sunscreens (clumping, stickiness, slipping), is skin-friendly, and can be applied even over makeup. Specific details for implementing the invention

[0020] The structure and operating principle of a water-soluble patch and mist according to an embodiment of the present invention will be described in detail.

[0021] (1) Composition of the patch

[0022] The water-soluble patch of the present invention has a three-layer structure of an upper layer, a middle layer, and a lower layer, and each layer may be provided to have mutually different functions and materials.

[0023] The upper layer may be composed of a water-soluble protective film containing blue light blocking ingredients Aquaceria (cerium oxide) and LUMICEASE™ (hydrolyzed pea protein, glucose, sodium succinate).

[0024] The above upper layer can be designed to dissolve rapidly as soon as the mist is sprayed, so that the active ingredient can be released quickly and uniformly onto the skin surface.

[0025] Cerium oxide is dispersed in the form of nanoparticles and effectively absorbs and scatters light in the blue light range (380–500 nm), thereby preventing skin damage.

[0026] LUMICEASE™ can improve the skin's protective function by preventing photodamage to skin cells and promoting the recovery of already damaged skin cells.

[0027] The middle layer can be composed of collagen and a hydrophilic polymer network.

[0028] Hydrophilic polymers such as polyvinyl alcohol (PVA) and polyvinylpyrrolidone (PVP) can be used; when a mist is sprayed, they rapidly absorb moisture, expand, and dissolve immediately.

[0029] Collagen provides skin adhesion and moisturizing power, and after rapidly dissolving in the mist, it is quickly absorbed into the skin to perform moisturizing and skin elasticity enhancement functions.

[0030] The lower layer is a layer for enhancing skin protection and moisturizing functions, and may be equipped to include skin protection and moisturizing ingredients such as hyaluronic acid, panthenol, allantoin, vitamin C derivatives, vitamin E, and coenzyme Q10.

[0031] These underlying ingredients are delivered directly to the skin when the patch dissolves, providing moisturizing and skin soothing effects.

[0032] (2) Role and function of mist

[0033] The mist can be equipped not only with the function of immediately dissolving the patch, but also with additional protective ingredients to create a synergistic effect with the patch.

[0034] The hydrophilic active agent in the mist induces the patch to dissolve uniformly and forms a protective barrier on the skin surface.

[0035] In addition, it plays a role in controlling the dissolution rate of the patch depending on specific environmental conditions (temperature, humidity).

[0036] In addition, it may be equipped with blue light and UV blocking ingredients to enhance the effectiveness of the patch.

[0037] Through this design, the patch of the present invention can be used more effectively and practically compared to existing products.

[0038] The present invention may be configured to control the stepwise dissolution rate through the reaction between the mist and the patch.

[0039] More specifically, the present invention may be configured so that the dissolution rate can be controlled through a reaction between a patch and a mist under specific temperature and humidity conditions.

[0040] Specifically, the patch and mist of the present invention may be configured such that the dissolution rate is highest at (25 to 35°C) and humidity (40 to 70% RH).

[0041] The dissolution promoter in the mist of the present invention reacts with the hydrophilic polymer network on the patch surface to control the dissolution rate.

[0042] Under high humidity conditions, dissolution is further promoted, while in dry environments, it can be controlled to dissolve slowly.

[0043] Meanwhile, specific components within the mist are activated depending on the temperature, which can provide rapid dissolution or continuous protective effects.

[0044] The present invention may be provided to form a transparent protective film on the skin surface by dispersing a blue light blocking component into nanoparticles with a size of 20 to 100 nm.

[0045] Conventional blue light blockers have large particle sizes, which can cause clumping when applied to the skin, but the present invention enables uniform distribution by utilizing nanotechnology.

[0046] Meanwhile, nanoparticles absorb and scatter specific wavelengths of blue light (380–500 nm), thereby maximizing the blocking effect.

[0047] Because a transparent protective film is formed, it can be applied naturally even over makeup.

[0048] The patch of the present invention may be provided with a hydrophilic polymer network comprising polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP), or a mixture thereof.

[0049] PVA and PVP have excellent hydrophilicity, rapidly absorbing moisture from the mist to allow the patch to dissolve quickly.

[0050] It provides high solubility and skin adhesion, forming a structure that is absorbed into the skin immediately after mist spraying.

[0051] Therefore, the dissolution speed and skin protection effect can be optimized by adjusting the mixing ratio.

[0052] The lower layer of the patch of the present invention may include skin-protecting and moisturizing ingredients such as hyaluronic acid, panthenol, allantoin, vitamin C derivatives, vitamin E, and coenzyme Q10.

[0053] Hyaluronic acid enhances skin hydration and maintains elasticity, panthenol strengthens the skin barrier and provides a soothing effect, and allantoin promotes skin regeneration and offers protection. Vitamin C derivatives and Vitamin E provide antioxidant effects that minimize skin damage from UV rays and blue light, while Coenzyme Q10 activates skin cell energy and enhances protective functions.

[0054] Specific embodiments of the present invention are as follows.

[0055] [Example 1]

[0056] An example in which blue light blocking ingredients are included only in the patch

[0057] The patch may be provided to include collagen, hydrophilic polymers (polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP)), Aquaceria (cerium oxide), and LUMICEASE™ (pea protein extract).

[0058] The mist contains only UVA and UVB blocking ingredients and can be configured to dissolve immediately upon spraying onto the patch.

[0059] [Example 2]

[0060] An example in which both the patch and the mist contain blue light blocking ingredients

[0061] The patch is configured to include collagen, a hydrophilic polymer (PVA or PVP), Aquaceria, and LUMICEASE™.

[0062] The mist also contains Aquaceria and LUMICEASE™ to block UVA, UVB, and blue light simultaneously.

[0063] [Example 3]

[0064] If only the mist contains blue light blocking ingredients

[0065] The patch may contain collagen and UVA and UVB blocking ingredients, and the mist may be equipped to provide blue light blocking functions by including Aquaceria and LUMICEASE™.

[0066] The patch can be provided with a multi-layered structure.

[0067] The patch has a multilayer structure of an upper layer, a middle layer, and a lower layer, and the upper layer may be equipped to contain a blue light blocking ingredient (Aquaceria, LUMICEASE™), the middle layer may contain collagen and hydrophilic polymers, and the lower layer may be equipped to contain moisturizing and skin-protecting ingredients.

[0068] When the patch reacts with the mist, it dissolves in stages, providing a continuous skin protection effect.
