Description

Cosmetic apparatus and solid cosmetics and solid liquid mixed cosmetics using the same

The present invention relates to a cosmetic device, and more particularly, to a cosmetic device including a micro-needle structure capable of effectively penetrating cosmetic ingredients into the skin and reducing the use of preservatives.

In general, cosmetic compositions contain water and oil as main components and contain many carbon sources such as glycerin or sorbitol, amino acid derivatives, proteins, etc.

Accordingly, in the prior art, it was common to add a preservative to a cosmetic composition in order to secure the shelf life of the cosmetic by preventing the change and contamination of the formulation caused by the penetration of microorganisms during use of the cosmetic.

When a preservative is formulated in a cosmetic, it suppresses the growth of microorganisms that penetrate into the cosmetic from the outside and contaminate the cosmetic, thereby killing the microorganisms over time. As such, preservatives are used for the purpose of preventing deterioration of products. The action of inhibiting the growth of microorganisms as described above is called a bacteriostatic action, and the preservative prevents the deterioration of cosmetics by this bacteriostatic action.

Representative examples of preservatives are chemical preservatives called paraoxybenzoate or parabens. It was taken for granted in the industry to add these chemical preservatives when manufacturing cosmetics. However, there is a problem that parabens accumulate in the body. When parabens accumulate in the body for a long time, they disrupt the hormonal system and are not beneficial to health at all. In particular, parabens cause more problems for women who use cosmetics for the rest of their lives because they try to pretend to be female hormones. For example, it increases the risk of breast cancer in women and is very dangerous for the fetus of pregnant women.

In addition, there is a problem in that certain of the active ingredients having an effect on skin care are decomposed or denatured over time when supplied in a liquid form, thereby reducing their effectiveness.

The present invention has been devised to solve the above problems, and an object of the present invention is to provide a cosmetic appliance that can secure the shelf life of cosmetics without reducing or using the amount of preservatives to be used in cosmetics.

Another object of the present invention is to provide a cosmetic device capable of maximizing the effect of cosmetics without reducing the effect of the active ingredient even over time by enabling the active ingredient effective for skin care to be activated immediately before use.

Another object of the present invention is to provide a cosmetic device so that active ingredients effective for skin care as described above can be smoothly supplied into the skin.

In order to solve the above problems, the present invention provides a cosmetic device having a microneedle manufactured to contain an active ingredient effective for skin care.

The microneedles are supplied and distributed in a solid phase, and may be changed into a liquid phase when a user uses a cosmetic device and supplied deep into the skin.

The microneedle is made of a water-soluble polymer component, and can be dissolved by water or lotion.

The microneedle can be effectively manufactured in the form of a film (so-called needle sheet) having a needle shape on the surface, and for user convenience, the needle sheet is attached to a support surface member having a predetermined rigidity. can provide Then, the user can rub the needle sheet on the skin by gripping the support surface member.

In order to ensure that the needle sheet is easily dissolved by the water-soluble component while well adhering the needle sheet to the support surface member, the needle sheet may be attached to the support surface member by a water-soluble, low molecular weight adhesive layer.

In order to secure the adhesion of the low molecular weight adhesive layer, the surface of the support surface member may be made of a polymer resin including a hydrophilic group.

Then, as the adhesive layer dries, the needle sheet can be well attached to the support surface member, and when a water-soluble component is supplied when a user uses it, both the needle sheet and the adhesive layer can be easily dissolved by the water-soluble component .

In addition, since the adhesive layer is composed of a water-soluble low-molecular component, a water-soluble component such as a lotion can be easily supplied to the needle sheet through the adhesive layer from the rear of the adhesive layer.

A liquid viscous pressure-sensitive adhesive is applied to the surface of the support surface member 31 to form the pressure-sensitive adhesive layer 40 . And the needle sheet 50 is laminated on the adhesive layer 40 . When the adhesive layer 40 is dried, the adhesive layer 40 maintains the state in which the support surface member 31 and the needle sheet 50 are attached to each other.

The needle sheet 50 includes a film layer 51 having a front surface and a back surface, and a plurality of fine microneedles 52 protruding forward from the surface of the film layer 51 . The microneedle 52 penetrates the skin and finely perforates the skin.

The film layer 51 and the microneedle 52 include a solid polymer cosmetic material. The film layer 51 and the microneedle 52 are manufactured in a solid state using the polymer cosmetic as a material. The film layer 51 and the microneedle 52 may be made of the same material. In addition, the film layer 51 and the microneedle 52 may be made of a polymer material, and may have an average molecular weight corresponding to each other or may have different average molecular weights. For example, it may be made of a polymer material including hyaluronic acid.

The needle sheet 50 is a solid, but water-soluble material, so it is well dissolved in a water-soluble component (lotion). The needle sheet 50 may include an EGF growth factor, and a component that is activated when dissolved.

The needle sheet 50 may itself be a solid cosmetic, water-soluble, and preferably has a moisture content of 5% or less. The solid cosmetic can be dissolved in the liquid cosmetic and applied to the skin therewith.

The microneedle 52 is used in a solid state and finely perforates the user's skin, and then the needle sheet 50 is dissolved in the lotion injected by the lotion injection device 70 and applied to the skin together. Then, the mixed component of the needle sheet 50 and the lotion can be smoothly supplied into the microperforated skin. At this time, the active ingredient that is activated only as the needle sheet 50 and the lotion are mixed can be provided.

The water-soluble needle sheet 50 may be well attached to the surface of the support surface member 31 according to the following principle.

First, at least a portion of the support surface member to which the adhesive layer is applied is made of a polymer resin including a hydrophilic group (eg, OH ⁻ ). And the pressure-sensitive adhesive layer 40 is made of a water-soluble low-molecular pressure-sensitive adhesive containing a hydrophilic group. Then, the adhesion between the adhesive layer 40 and the support surface member 31 may be very large. The pressure-sensitive adhesive is applied on the surface of the supporting surface member as a viscous liquid, and dried while the needle sheet 50 is attached to the applied pressure-sensitive adhesive to become a solid. Since the needle sheet 50 is also a water-soluble polymer component that dissolves well in the lotion, it adheres well to the pressure-sensitive adhesive.

The needle sheet 50 can be said to be a kind of solid film-type cosmetics. It can be manufactured only with approved raw materials as cosmetic raw materials for skin care. The needle sheet 50 changes from a solid phase to a liquid phase by moisture. When the needle sheet 50 is in a solid state, a solid microneedle 52 is provided on the surface thereof, and a film layer 51 forming a cosmetic layer of a certain thickness is provided under the microneedle 52 .

The adhesive layer is composed of a water-soluble low-molecular layer having a molecular weight of 50,000 or less. When the molecular weight of the material of the needle sheet 50 and the molecular weight of the adhesive layer 40 are compared, the molecular weight of the needle sheet 50 is greater.

A support surface for evenly applying pressure to the microneedles 52 is provided under the adhesive layer 40 to pierce the skin with the microneedles 52 . In the embodiment, it is exemplified that the support surface is a support surface member 31 having a predetermined rigidity. However, the support surface may be made of another film.

The water-soluble low molecular weight of the adhesive layer 40 refers to a viscous material that is applied to the surface of a different material in an aqueous solution state and dried to enable strong adhesion. When it is in a solid state, it strongly adheres to the support surface for pressure, and when moisture is added, it dissolves quickly, so that the film-type cosmetic (needle sheet) can be easily separated from the support surface and dissolved. The following water-soluble small molecules are meant.

As a material constituting the needle sheet 50 and the adhesive layer 40 of the present invention, any material that is easily dissolved when in contact with moisture or body fluid and is pharmaceutically or medically acceptable may be used. For example, among natural polymers, hyaluronic acid, alginic acid, pectin, carrageenan, chondroitin (sulfate), dextran (sulfate), chitosan, polylysine, collagen, gelatin, Carboxymethyl chitin, fibrin, agarose, pullulan, cellulose, etc. may be used, and among synthetic polymers, polyethylene oxide, poly(N-) isopropyl acrylamide (PNIPAAm), polyacrylamide (PAAm), Polymers of hydrophilic monomers such as polymethacrylic acid, polymaleic acid, polyvinyl alcohol (PVA), polyethylene oxide (PEO), poly(N-)vinylpyrrolidone (PVP), etc., poly(MMA-co-HEMA)(Poly) Copolymers such as (methyl methacrylate-co-hydroxylethyl methacrylate), poly(acrylonitrile (AN)-arylsulfonate), P (glucosyloxyethyl methacrylate (GEMA)-sulfate), or PEO-polyester (PLA, PCL, PLGA, etc.) derivatives, PEO-PPO-PEO ternary block copolymer, N-carboxyanhydride, etc. may be used alone or in combination. However, the material is not necessarily limited thereto.
