Description

Gel cosmetic composition for ultrasonic beauty device and its manufacturing method {GEL COSMETIC COMPOSITION FOR ULTRASONIC COSMETIC APPARATUS AND PREPERATION METHOD FOR THE SAME}

Embodiments relate to a gel cosmetic composition for an ultrasonic cosmetic device that exhibits excellent effects such as spreadability, applicability, gel retention, ultrasonic permeability, residual feeling, and skin moisturizing, and a method for manufacturing the same.

Skin aging inevitably progresses with the passage of time, and suppression of skin aging by using cosmetics applied to the skin inevitably has physical limitations. As a means for overcoming the limitations of suppressing skin aging by cosmetics, beauty devices such as ultrasonic beauty devices and high frequency beauty devices have been developed and widely spread and utilized.

Ultrasonic beauty devices deliver ultrasonic vibrations to the skin to obtain various cosmetic effects. It is possible to increase skin elasticity and reduce wrinkles through transdermal injection of various cosmetics using ultrasound. In addition, by causing fine vibrations between human tissue and skin cells to generate heat and mechanical energy, metabolism of the skin can be promoted. In addition, by activating fibroblasts in the dermis to promote the synthesis of collagen and elastin, wrinkles can be unfolded.

The gel used in the ultrasonic beauty machine uses a gel for ultrasound examination or a nutrient cream, but the diagnostic gel simply serves as a delivery medium, and the nutrient cream usually has a problem in that it has a poor feeling of use as an emulsifier.

Hereinafter, an embodiment will be described in more detail.

In order to achieve the above object, the gel cosmetic composition for an ultrasonic cosmetic device (hereinafter abbreviated as a composition) according to an embodiment includes 0.1% to 2.0% by weight of a thickener, 0.001% to 3.0% by weight of an antioxidant, and 0.1% by weight of a moisturizer. % to 10.0% by weight, neutralizing agent 0.1% to 1.0% by weight, skin conditioning agent 0.0001% to 30% by weight, film forming agent 0.001% to 1.0% by weight, and the balance of an aqueous solvent.

The film forming agent includes a copolymer of methyl vinyl ether and maleic anhydride.

The film forming agent forms a film on the surface to which the composition is applied to enable stable and smooth ultrasonic treatment, and also serves to protect the surface.

The composition of the embodiment may include 0.001% by weight to 1.0% by weight of the film forming agent. If the content of the film-forming agent is less than 0.001% by weight, the film-forming effect may be insignificant, and if it exceeds 1.0% by weight, the surface may feel dull or stuffy.

The film-forming agent may be applied in an amount of 0.003% to 0.1% by weight, based on the total weight of the composition, and may be applied in an amount of 0.003% to 0.05% by weight. In this case, it is possible to obtain a stable formulation while appropriately obtaining the film-forming effect.

A thickening agent is applied to control the viscosity of the composition and to adjust applicability, spreadability, gel retention, and the like.

In embodiments, thickeners may include Carbomer and PolyacrylateCrosspolymer-6. When the thickener is applied in an amount of less than 0.1% by weight, the viscosity of the composition is insignificant, so it may not be suitable for a gel formulation or the feeling of use may not be good. It may be stiff and the feeling of use may deteriorate.

The composition of the embodiment may include 0.1 to 0.5 parts by weight or 0.2 to 0.35 parts by weight of the polyacrylate crosspolymer-6 based on 1 part by weight of the carbomer. In this case, it is possible to maintain a stable emulsification with a viscosity similar to that of the gel for ultrasound.

The composition of the embodiment may include 100 to 200 parts by weight of the thickener based on 1 part by weight of the film forming agent. The ratio of the film-forming agent and the thickener is important to impart a fresh feeling or leave a residual feeling when using the composition. The composition may include 100 to 200 parts by weight or 120 to 175 parts by weight of the thickener based on 1 part by weight of the film forming agent, and in this case, an excellent formulation with a minimized residual feeling may be provided.

Antioxidants may include, for example, hydroxyacetophenone and green tea extract.

If the composition of the embodiment contains less than 0.001% by weight of the antioxidant, the antioxidant effect may be insignificant, and if it contains more than 3.0% by weight, the antioxidant may be wasted unnecessarily. The composition contains 0.1 to 1.0% by weight of the antioxidant to obtain a stable formulation while obtaining a sufficient antioxidant effect.

Moisturizers may include glycerin and dipropylene glycol.

If the composition of the embodiment includes less than 0.1% by weight of the moisturizer, the moisturizing effect may be insignificant, and if it contains more than 10.0% by weight, the stability of the formulation may be lost or the feeling of use may be reduced due to a residual feeling.

Neutralizing agents include tromethamine.

The neutralizing agent may act as an acidity regulator.

When tromethamine is applied as the neutralizing agent, the acidity control effect and the effect of reducing the stickiness of the formulation can be obtained at the same time.

When the composition of the embodiment contains less than 0.1% by weight of the tromethamine, the effect of adjusting acidity and reducing stickiness may be insignificant, and when applied at 0.3% to 0.8% by weight, the effect is excellent.

Skin conditioning agents are applied for purposes such as skin soothing and oil-moisture balance control.

The skin conditioning agent is glycereth-26, allantoin, dipotassium glycyrrhizate, caprylyl glycol, glyceryl acrylate/acrylic acid copolymer, kava kava leaf/root/stem extract, centella asiatica extract, bark tree fruit It may include any one selected from the group consisting of extract, Pasqueflower extract, Usnia extract, and combinations thereof.

If the composition of the embodiment contains less than 0.0001% by weight of the skin conditioning agent, the skin conditioning effect may be insignificant, and if it contains more than 30% by weight, stability of the formulation may decrease.

The aqueous solvent includes purified water and alcohol.

The alcohol may include any one selected from the group consisting of butyl alcohol, hexanediol, and combinations thereof. The alcohol may serve as a solvent and a preservative at the same time.

The butyl alcohol may be included in an amount of 0.002% to 1.0% by weight based on the total weight of the composition, and it is preferable to use t-butyl alcohol.

The hexanediol may be included in an amount of 0.02% to 3.0% by weight based on the total weight of the composition, and 1,2-hexanediol is applied.

The aqueous solvent may be applied in the remaining amount of the above components.

The composition of the embodiment is excellent for application to ultrasonic beauty devices as a crystal-type formulation, and in particular, is excellent in all aspects of spreadability, applicability, gel retention, and skin irritation, and is excellent to leave little residue, and also helps in moisturizing or elasticity of the skin. can give
