Description

{COSMETIC PACK FOR HAND OR FOOT}

More particularly, the present invention relates to a cosmetic pack for a human body, and more particularly, to a cosmetic pack for a human body, which comprises a cosmetic liquid carrying layer containing an oil-soluble serum and a hydrophilic foam layer, The present invention relates to a cosmetic pack for an aquatic body, in which absorption of a serum is accelerated by a repulsive action with an oil-soluble serum.

Paraffin therapy is a treatment for immersing hands or feet in molten paraffin at 48 ° C to 63 ° C. It was originally used for physical therapy and the like, but paraffin has been found to moisturize and whiten skin. The use was expanded.

A typical paraffin therapy device is manufactured in the form of a heater that receives and melts a predetermined amount of paraffin. When such a heater is used, a large amount of expensive paraffin is used more than necessary, which is costly and requires a long time There is a drawback that it takes time.

To overcome this disadvantage, there is a disposable paraffin hand pack (Korean Patent Laid-Open Publication No. 2007-0096207) that can reduce the waste of paraffin by filling paraffin in a glove shaped heater. However, There is a risk of burns because a metal heating element is installed inside the pack.

To eliminate the risk of burns, Bliss of the United States developed gloves and socks that coated paraffin inside. When the hands or feet were small, the coated paraffin did not come in direct contact with the hands or feet, There is substantially no cosmetic effect, and there is a disadvantage in that a lot of sweat is produced.

Therefore, it is necessary to develop cosmetic packs for swimmers that do not take up sweat without using expensive paraffin.

Korean Patent Publication No. 2007-0096207

In order to solve the problems of the prior art, the inventors of the present invention have developed a product which is not expensive paraffin but which is inexpensive polymer polymer but which can absorb sweat and promote absorption of a serum, Layer and a hydrophilic foam layer separately to absorb sweat selectively and to promote skin absorption of the liposoluble cosmetic solution due to the repulsive action between the hydrophilic polymer and the liposoluble cosmetic liquid.

An object of the present invention is to provide a cosmetic composition which is formed in a glove or a sock shape having an opening on one side so as to be worn on a hand or a foot and includes a non-permeable skin layer, a cosmetic liquid containing layer provided on the inner side of the skin layer, A hydrophilic foam layer adhered to the inner side of the film layer, and a plurality of through holes formed through the film layer and the hydrophilic foam layer.

In order to achieve the above object, the present invention provides a cosmetic composition comprising a non-permeable skin layer, a glove which is formed on one side of the glove or sock to be worn on the hand or foot, a non-permeable skin layer, A hydrophilic foam layer bonded to the inner side of the film layer, and a plurality of through holes formed through the film layer and the hydrophilic foam layer, .

The cosmetic pack according to the present invention induces the user to directly massage, thereby providing a different method of using the cosmetic pack as compared with the conventional cosmetic pack, and promoting blood circulation of the hands or feet due to massage, The hydrophilic foam layer selectively absorbs perspiration, thereby facilitating penetration of the liposoluble serum into the skin and providing a pleasant feeling of use. The hydrophilic foam and the liposoluble serum react with each other, and the liposoluble serum penetrates rapidly into the skin.

Fig. 1 shows an embodiment in which the cosmetic pack of the present invention is manufactured in the form of gloves, and a cross section of the material constituting the cosmetic pack.
FIG. 2 schematically shows a state in which when a cosmetic pack of the present invention is worn and pressure is applied to the skin layer, the liposoluble serum of the serum-free layer reaches the skin through the through-hole and the hydrophilic foam layer absorbs perspiration.

For a better understanding of the present invention, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

2, when the cosmetic pack of the present invention is worn on the hand or foot and then the cosmetic pack 20 of the cosmetic pack is pressed with pressure, the cosmetic pack 30 (30) ) Passes through the plurality of through holes (60) to reach the skin. When the temperature inside the beauty pack is raised and sweat is generated over time, the hydrophilic foam layer (50) selectively absorbs perspiration . The hydrophilic foam layer 50 has a hydrophilic property, thereby providing a pleasant feeling by selectively absorbing perspiration other than the lipid-soluble serum, enhancing the concentration of the lipid-soluble serum on the skin, allowing penetration of the serum into the skin, And the hydrophilic foam layer 50 has a repulsive action with the above-mentioned fat-soluble serum, thereby significantly promoting skin absorption of the fat-soluble serum.

The non-permeable skin layer 20 included in the cosmetic pack of the present invention is preferably made impermeable because it is required to prevent leakage of the oil-soluble serum carried on the serum-lipid layer 30, It is desirable to have flexibility so as to facilitate this.

The non-permeable shell layer 20 may be formed of any material including, but not limited to, natural rubber, polyisoprene, polychloroprene, polybutadiene, styrene butadiene rubber (SBR) Acrylonitrile butadiene rubber, ethylene propylene diene monomer (EPDM), chlorosulfonated polyethylene (CSM), dibutoxyethoxyethyl adipate (DBEA), poly Polyolefins such as polyepichlorohydrin (PECH), polyurethane (PU), ethylene acrylic acid copolymer (EAA), tetrafluoro ethylene / propylene rubbers (FEPM), perfluoro- Perfluoroelastomers (FFKM), polynorbornene, silicon, and combinations of at least one of the foregoing. Jean lure can be made from a material selected from the group.

Examples of the hydrophobic polymer include hydrophobic polystyrene (PS), hydrophobic ethylene (EVA), hydrophobic polycarbonate (PC), hydrophobic polymethyl methacrylate (PMMA), hydrophobic Teflon (PTFE), hydrophobic polyethylene (PE), hydrophobic polyvinyl alcohol, hydrophobic polypropylene, &Lt; / RTI > and combinations thereof.

The fat-soluble essence refers to a serum, which contains a fat-soluble component that helps to improve skin. The fat-soluble component may be any of the fat-soluble cosmetic ingredients used in the art including, but not limited to, vitamin A or its precursor, vitamin D Or a precursor thereof, vitamin E or a precursor thereof, natural vegetable oil, cholesterol, ceramide, fatty acid, phospholipid, squalene, lipid soluble coenzyme Q10, lycopene and combinations thereof.

In addition, the serum-free layer 30 may further include a water-soluble serum-free layer. The water-soluble essence may be any of the water-soluble cosmetic ingredients used in the art including, but not limited to, water-soluble collagen, vitamin B or its precursor , Vitamin C or its precursor, soluble collagen, amino acid, water-soluble plant extract, water-soluble proteoglycan, water-soluble ceramide, hyaluronic acid, and combinations thereof.

The cosmetic pack of the present invention comprises a film layer 40 provided inside the serum-free layer 30, a hydrophilic foam layer 50 adhered to the inside of the film layer 40, and a film layer 40 and a hydrophilic foam layer 50 And a plurality of through holes 60 formed through the through holes 60.

The film layer (40) provided inside the serum-free layer (30) prevents the skin-soluble serum carried on the serum-free layer (30) from leaking out before wearing the cosmetic pack of the present invention. The cosmetic pack of the present invention massage the hands or feet after wearing and the oil-soluble cosmetic solution flows out from the cosmetic liquid carrying layer 30 through the plurality of through holes 60 to reach the skin of the hands or feet. Such use induces hand or foot massaging to help blood circulation in the hands or feet, making the skin better, and allowing the user to actively participate in the massage, thus differentiating it from the products that were previously only passively worn Thereby enhancing product preference.

The material of the film layer 40 may be any material that can prevent the oil-soluble essence from leaking out, and it is preferable that the material is flexible because it is easy to wear on the hands or feet as in the case of the skin layer 20. Preferably, Therefore, it is preferable to have an oil resistance for the stability of the product. In one embodiment, the film layer may comprise the same material as the shell layer.

The hydrophilic foam layer 50 may comprise a hydrophilic material, such as a hydrophilic polymeric polymer. The hydrophilic polymer may be a hydrophilic polymer polymer modified with hydrophilic poly (ethylene glycol) (PEG), hydrophilic polyacrylonitrile (PAN), hydrophilic polyurethane (PU), hydrophilic polyvinyl alcohol (PVA) , Nylon (nylon 6), hydrophilic polyvinylidene fluoride (PVDF), hydrophilic polyether sulfone (PES), hydrophilic polyetherimide (PEI), and combinations of at least one of the foregoing.

In one embodiment, the coating composition may comprise titanium dioxide sol, silica sol, zinc oxide sol and silver in a weight ratio of 1: 1: 1: 1, respectively.

When the coating composition contains the above components in the composition ratio, it is possible to secure physical properties required as a material for gloves such as uniform application force and bonding strength with the hydrophilic foam layer.

In one embodiment, the ratio of the cross-sectional area of the through-hole to the area of the portion of the hydrophilic foam layer other than the cross-sectional area of the through-hole may be from 1: 1 to 1:19. For example, if the ratio of the cross-sectional area of the light hole to the area of the portion of the hydrophilic foam layer other than the cross-sectional area of the through hole is less than 1: 1, the through hole becomes excessively wide and the sweat- , The mechanical properties of the cosmetic pack may be weakened. In addition, when the ratio is more than 1:19, the effect of transferring the serum can be remarkably weakened. The ratio of the area of the hydrophilic foam layer excluding the cross-sectional area of the through-hole may preferably be from 1: 8 to 1:10.

It will be apparent to those skilled in the art that various modifications and equivalent arrangements may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.

(Production Example 3), about 50% (Production Example 4), about 17% (Production Example 5), about 10% of the surface area of the sheet (Production Example 6), about 5% (Production Example 7), and 4% (Production Example 8).

[Production Example 9]

A glove was prepared in the same manner as in Preparation Example 1 except that a hydrophilic foam layer was not formed.

[Production Example 10]

Gloves were produced in the same manner as in Production Example 1 except that polyethylene, which is a material mainly used as an inner skin of commercial cosmetic gloves, was used instead of hydrophilic foam.

[Production Example 11]

A glove was prepared in the same manner as in Preparation Example 5 except that the hydrophilic foam layer was not coated with the coating liquid.

[Production Examples 12 to 17]

1: 1: 1: 1, 1: 1: 2: 1, 1: 1, and 1: 2 by weight of titanium dioxide sol, silica sol, zinc oxide sol and silver in a ratio of 1: 0.5: : 1: 0.5, and 1: 1: 1: 2, respectively.

[Production Examples 18 to 23]

Titanium dioxide was prepared by mixing titanium isopropoxide with isopropanol in a molar ratio of 1: 3 or 1: 7 (Production Examples 18 and 19), mixing tetraethylorthosilicate and isopropanol in a 1: 2 or 1: 6 (Preparation Examples 20 and 21), zinc oxide and isopropanol were mixed in a molar ratio of 1: 3 or 1: 7 in the zinc oxide sol (Production Examples 22 and 23) 1, gloves were prepared.

[Experimental Example 1] Confirmation of improvement effect on feeling and skin condition

Twenty women in their 20s and 50s who had no skin disease were subjected to a feeling test and a skin condition improvement test on the following items. The feeling and the skin condition improvement result were averaged by summing the scores of each panel.

1. Feeling due to sweat discharge

The gloves of the above-mentioned production examples were evaluated, and after one hour had elapsed, it was evaluated whether or not the gloves were sweaty to cause irritation. 0 point: feeling is not very good ~ 10 points: feeling very good

2. Skin condition improvement effect

The gloves were worn for one hour each, and after 24 hours passed, the panel condition was tested for skin condition improvement (skin gloss, softness, etc.). In order to accurately determine the effect of each glove, the experiment was conducted for at least one week for each glove use. 0 point: No skin condition improvement effect ~ 10 points: Skin condition improvement effect is very good

As a result, it was found that when the area of the through hole was about 60% or more, the feeling of use dropped sharply (Production Example 3), no hydrophilic foam was used (Production Example 9) I could see that my sweat was falling and my feeling was poor.

In the case where there is no through hole (Production Example 2), the area of the through hole exceeds 50% (Production Example 3), the area of the through hole is too narrow (Production Example 8) 9). In the case of using common materials in the market (Production Example 10), it was found that the beauty liquid was not easily transferred to the hands, and the skin condition improving effect was insignificant (Table 1).

In addition, when the hydrophilic layer was coated with the hydrophilic and oil-based coating solution, it was confirmed that the coating layer had remarkably excellent feeling and skin improving effect as compared with the case without coating (Production Example 11).
