Description

Sheet type hydrogel pack agent and its manufacturing method {sheet-type hydrogel pack}

The present invention relates to a hydrogel state pack for use in functional cosmetics for skin improvement (whitening, anti-aging, anti-wrinkle, etc.) and a method of manufacturing the same.

A pack is originally a 'wrapping' meaning that wraps an active substance in the face to remove pores, cleans the skin and effectively supplies moisture and beauty ingredients to the skin to maintain blood circulation and restore skin physiology. It is a kind of cosmetics.

Since the pack can provide various nutrients to the skin very effectively, it can be expected to have various effects such as moisturizing, soothing, aging, removing dead skin cells and wastes, restoring tired skin, enhancing elasticity and whitening by these cosmetic ingredients. In addition, the pack can pull the skin as the membrane shrinks when the pack is dried to create a tension on the skin, as well as to improve the elasticity of the skin and relieve fine wrinkles by the adhesion and massage effect that appears when the membrane is peeled off.

In addition to the cosmetic and health effects described above, the psychological stabilizing effect can be alleviated by supplying a rest to the tired face and body with a comfortable mind for the time it takes to apply the pack to the skin and then dry it. You can expect

Packs are divided into peel-off packs, wash-off packs, and tissue-off packs, depending on the type. After elapsed, the dried film is peeled off and has a function of moisturizing, skin elasticity recovery, sebum and waste removal.

In addition, the wash-off type is a form to wash the face after applying the pack to the face and has the functions of moisturizing, soothing, fatigue recovery and nutrition.

In addition, the tissue-off pack is a form of applying a cream-type pack to the face, absorbing some of the nutritional ingredients of the pack into the skin and then wiping the remaining pack with a towel.

Packs of nonwoven fabrics that are widely commercialized nowadays can also be seen as a kind of tissue-off packs, but they can be classified into independent forms as they are diversified.Non-woven fabric packs containing nutrients or wrinkle-reducing ingredients Many products have been applied to the entire face, around the eyes, or around the mouth, or applied separately.In addition, parts packs can be used to remove sebum, old dead skin cells and waste products by using it on the nose and around the sebaceous glands. It is becoming.

On the other hand, a large number of pores exist in the human skin, but keratin is formed in the pores by secretions such as oil or sebum secreted from the skin itself or dust by external environment.

Since the formed keratin is not good for skin health and beauty, various methods are used to prevent or remove keratin. As a general method for preventing or removing keratin, a method of washing the skin using various cleansing agents or removing using various types of packs having the same effect is used. Facial cleansing with facial cleansing is effective in preventing keratinogenesis, but it is almost impossible to remove dead skin cells already formed in the pores.

In addition, a method of using a liquid pack agent in a tube, which is a kind of peel-off type, is a method of removing keratin while peeling the formed coating from the skin by applying a liquid water-soluble pack agent to the skin and then leaving it to dry for a predetermined time. Since the method is also a method of removing dead skin cells in the pores by the adhesive force of the film generated when the film formed on the skin is peeled off from the skin, a sufficient exfoliation effect cannot be expected.

Moreover, the method of using such a coating liquid pack agent is difficult for the user to apply a uniform thickness to his skin, so that the dry state of the film formed by leaving it for a certain time becomes uneven and partially does not dry completely. If the coating is peeled off from the skin, there is a problem that the pack agent may remain on the skin. In addition, the thin portion of the coating film applied to the skin is also easy to tear during peeling, there is a problem that takes a long time to remove the entire film because the fracture pieces remain in the skin.

In order to solve such a problem, it is necessary to apply a thick pack and dry it for a longer time, but this method lacks simplicity and lacks practicality, and increases the consumption of the pack and is not economical.

Therefore, in order to overcome the problems of the conventionally used pack agent, sheet-type pack agents have been proposed that do not need to be washed in a simple sheet type and that the pack agent does not remain on the skin even when peeled from the skin. It not only supplies moisture and nutrients evenly across your face, but also is very effective to intensively manage your skin dry within 15 to 30 minutes.

In addition, water was used as a dispersion medium, and a part of the water molecule was hydrogen-bonded to the polar group of the chain-shaped molecule to use a hydrogel that surrounds the molecule in the form of a protective net as a pack agent. Hydrogels are water-free, non-sticky, swelled by water or other liquids, and have a certain degree of roughness. They are already used in semi-solid preparations. Formulations have been developed that enhance the moisturizing and nourishing or exfoliating effect of the pack.

The benefits of using a device containing patches, eg, water soluble polymerizable gel formers, in place of creams and lotions, etc. to cosmetically treat the skin or to facilitate the treatment of burns or wounds are known in the prior art. have. Various cosmetic patches or devices are commercially available or have been described as useful for the delivery of skin care actives such as vitamin actives, anti-wound actives, hydrating agents and the like. Patches and devices have been described in various literatures and are commercially available in the medical field as a useful means for transdermal administration of medicines.

In recent years, Japanese Patent Application Laid-Open No. 54-49334, a pack agent, discloses a low peeling pack agent having excellent water-retaining ability mainly containing polyacrylate, polyhydric alcohol and water. Japanese Unexamined Patent Publication No. 1-46485 discloses a sheet-like pack agent using a cross-linked hydrogel as a base, and Japanese Unexamined Patent Publication No. 5-295004 discloses a pack agent blended with a natural-derived semisynthetic component as a moisturizer and thickener. It is.

However, the conventional pack agent has a problem that the pack action is not sufficient, and a feeling of discomfort such as a feeling of pressure and tingling at the time of patching is likely to occur, and even in the present day, which is called a sheet cosmetic boom, the user's relaxation requirements cannot be satisfied. I had a problem.

In addition, Japanese Patent Application Laid-Open No. 8-283147 discloses an aqueous pressure-sensitive adhesive composition which is durable when applied to the skin as an external preparation and gives a moderate level of cooling. However, the composition is used only as a component of an external preparation such as a poultice sheet, and has not been studied at all as being used as a component of a sheet-like pack agent.

Therefore, there is an urgent need for the development of a sheet-like pack agent having a pack action excellent in the effect and stability on the skin, and the relaxation effect of the mind and body, without losing proper adhesiveness to the skin.
