Description

Underarm water gel patch

This creation relates to a hydrogel patch, especially a submerged water gel patch having an active substance.

Under the armpit, it is easy to sweat, and the chance of breeding skin diseases is high. If it is necessary to apply a patch that has absorption function and is breathable and not easy to fall off, the traditional patch cannot be achieved. Traditional patch is made up of natural plant fiber or animal hair, such as gauze, cotton pad, wool, all kinds of oil gauze, etc. It is too thick and has no stretchability. It is not suitable for sticking under the armpit and can not be sweated. Sticking, plastic stickers can be used to stick, but they are not able to absorb sweat and breath, and are not suitable for underarms.

Transdermal drug delivery is a comfortable, convenient, and non-invasive method of drug administration that avoids the variability in absorption and metabolism associated with oral therapy while eliminating other inconveniences such as gastrointestinal irritation and the like. When a therapeutic compound is delivered transdermally, the blood concentration of the drug can be highly controlled due to the constant flux rate at steady state.

Despite its many advantages, the low penetration or penetration of many drugs across the skin of a patient has become one of the key issues in transdermal administration. The skin is a structurally complex, relatively thick film. The molecule penetrates into the environment and passes through the intact skin. It must first penetrate the stratum corneum and then penetrate the viable epidermis, the papillary dermis and the capillary wall into the bloodstream or drench. In the channel. Translocation across the skin membrane is therefore a complex phenomenon. It poses a great challenge to the development of transdermal drug delivery systems.

Underarms are important parts of the body. People's activities in daily life or climatic factors make the underarms often sweaty, easily breed skin diseases or accumulate bacteria to cause odors. These conditions make the patches attached to the underarms easy to fall off.

In order to solve the problem that the patch is easy to fall off when using the underarm, the creator improved the conventional patch to obtain an underarm patch containing the active ingredient.

The present invention provides an underarm water gel patch comprising: (a) a polyurethane film layer which is a single direction permeable film; (b) a pressure sensitive adhesive layer which is a hydrophobic material and is coated on the polyurethane a film layer that bonds the polyurethane film layer to the skin; (c) a meltblown type nonwoven fabric having a multi-directional elastic tension attached to the pressure sensitive adhesive layer; (d) a hydrogel which is hydrophilic a material attached to the meltblown type nonwoven fabric; and (e) a web-like interlaced polymer which is irradiated with ultraviolet light by a portion of the meltblown nonwoven fabric and a portion of the hydrogel The partial fiber of the melt-blown non-woven fabric is stably adhered to the pressure-sensitive adhesive layer, and the hydrogel is multi-directionally elasticized to adapt to different skin parts, wherein the polyurethane film layer and the pressure-sensitive adhesive layer are The double concave shape allows the underarm hydrogel patch to be attached to the underarm.

A hydrogel patch according to the present invention, wherein the hydrogel comprises: (a) an active ingredient; (b) a monomer; (c) a plasticizer; (d) a photoinitiator; (e) a crosslinking agent; and/or (f) a thickener. In one embodiment, the active ingredient comprises a mint, whitening firming or shrinking pore component; in another embodiment, the active ingredient is a titanium anthraquinone.

According to the hydrogel patch of the present invention, the hydrogel absorbs a lot of sweat The skin is kept at the proper humidity and can move freely.

The preferred embodiment of the present invention will be described in detail below, wherein the figures of the embodiments are the same as those shown in the drawings, and the drawings and detailed description are also referred to. The following examples are not intended to limit the present invention, but merely represent a number of aspects and features of the present invention.

1 is a schematic view showing the structure of a submerged hydrogel patch 100 according to the present invention, comprising: (a) a polyurethane film layer 101 which is a single direction permeable film; and (b) a pressure sensitive adhesive layer 102 which is hydrophobic. a material coated on the polyurethane film layer 101 to bond the polyurethane film layer 101 to the skin; (c) a melt-blown nonwoven fabric 103 having a multi-directional elastic tension attached to the pressure-sensitive adhesive layer 102; (d) a hydrogel 104 which is a hydrophilic material attached to the melt blown type nonwoven fabric 103; and (e) a mesh-like interlaced polymer 105 which is a part of the melt blown type nonwoven fabric 103 And a part of the hydrogel 104 is adhered by ultraviolet light irradiation, and a part of the fiber of the melt-blown type undisclosed cloth 103 is stably adhered to the pressure sensitive adhesive layer 102, and is given to the hydrogel 104. Multi-directional elasticity to adapt to different skin parts. Here, the polyurethane film layer 101 and the pressure-sensitive adhesive layer 102 are referred to as an outer layer 106, and the melt-blown nonwoven fabric 103, the hydrogel 104, and the network-like interlaced polymer 105 are referred to as an inner layer 107.

Figure 2 is a schematic view of the use of the under-water gel patch 100 of the present invention. The present invention absorbs sweat from underarms through a hydrogel having a sweat-absorbing ability and a non-woven fabric interlacing polymer. The polyurethane film of 106 is adhered and antibacterial with the pressure sensitive adhesive, and the sweat penetrates into the micropores during the passage of the water vapor, so that the skin can be kept fresh. This creation can be used for the armpit 201 between the upper arm 202 and the chest side 203. , but not limited to this, you can also use it.
