Description

Spray composition for injecting on skin {Spray composition for injecting on skin}

The present invention relates to a composition for skin care, and in particular, to a composition containing a fluorocarbon-based surfactant to improve sprayability when sprayed on the skin in a spray form.

When using liquid cosmetics such as liquid foundation, essence, and toner, many people apply them to their face with their hands. This application method has several disadvantages as follows.

You must touch cosmetics with your hands, and you should usually wash your hands after applying them to your face. Additionally, there is a disadvantage in that it cannot be applied evenly when applied by hand, which reduces the efficacy of cosmetics. It takes a long time to apply by hand and the efficiency is low.

In addition, many people use mask packs for skin care, but they endure the hassle of applying the mask packs by hand to achieve various effects such as moisturizing.

The present invention proposes a composition containing raw materials that can provide various skin care. In particular, the present invention proposes a composition that is sprayed on a large surface area with sufficient spraying force when used in a spray form so that it can be sprayed on the skin for care.

The composition of the example is a composition that can be sprayed for skin care, and includes at least one of moss extract, kakadu plum extract, and seaweed extract, and a fluorocarbon-based surfactant contained to increase the surface area when sprayed. It is characterized by including.

In addition, the fluorocarbon-based surfactant is characterized in that it is included in the range of 0.01 to 5.0 wt% with respect to the composition.

In addition, the fluorocarbon-based surfactant is CF ₃ (CF ₂ ) _5-9 SO ₄ Na, CF ₃ (CF ₂ ) _5-9 SO ₄ K, CF ₃ (CF ₂ ) _5-9 SO ₄ NH _{4 ,} CF ₃ (CF ₂ ) _5-9 SO ₃ Na, CF ₃ (CF ₂ ) _5-9 SO ₃ K, and CF ₃ (CF ₂ ) _5-9 SO ₃ NH _4. It is characterized by mixing.

In addition, polyvinyl alcohol to play a role in forming a film on the skin and propylene glycol for a sterilizing effect are further included.

The composition according to this embodiment has the advantage that it can be used as a spray-type skin care product instead of an existing mask pack because it is sprayed onto a large surface area when sprayed due to a surfactant with low surface tension.

The detailed description of the present invention described below refers to the accompanying drawings, which show by way of example specific embodiments in which the present invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It should be understood that the various embodiments of the invention are different from one another but are not necessarily mutually exclusive. For example, specific shapes, structures and characteristics described herein with respect to one embodiment may be implemented in other embodiments without departing from the spirit and scope of the invention. Additionally, it should be understood that the location or arrangement of individual components within each disclosed embodiment may be changed without departing from the spirit and scope of the invention.

Hereinafter, in order to enable those skilled in the art to easily practice the present invention, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

The composition of the present invention has the characteristic of being sprayed on a sufficient surface area with a small spraying force when sprayed on human skin after being contained in a spray container capable of spraying.

In particular, it is a substance to enable various care for human skin, and contains at least one of moss extract, kakadu plum extract, and brown algae extract, and these substances reduce the surface tension of the fine particles sprayed when sprayed with water. It contains a fluorocarbon-based surfactant to lower the level and ultimately allow it to be sprayed over a wide surface area.

First, the moss extract constituting the composition of this example is used as a substance to improve skin moisturization.

Moss extract is a substance containing a large amount of isomalt, and as shown in Figure 1, a large amount of -OH groups are included in the molecular structure, which can improve skin moisturization when included in the composition.

Isomalt can be used as a sugar substitute, and when consumed in the human body, it does not stimulate the release of insulin, so it does not affect blood sugar levels and does not affect tooth damage. If included in a cosmetic composition for skin moisturizing care according to this embodiment, the moisturizing ability of the skin can be greatly improved due to the large amount of -OH groups contained.

Next, Kakadu plum extract may be included in the composition.

The Kakadu plum is a type of plum, and the name Kakadu comes from the Kakadu National Park in northern Australia. Although the Kakadu plum is known to be rich in nutrients, it is also known to be rare because it is difficult to grow elsewhere and is only grown in some parts of northern Australia.

Kakadu plums have been used as a common medicine by Australian aborigines since ancient times and contain vitamin C, which is 100 times that of oranges, 460 times that of blueberries, 58 times that of lemons, and 21 times that of kiwis. It contains vitamin C equivalent to that of a pear.

The composition of this example uses the Kakadu plum extract for use in skin care, and uses the Kakadu plum, which contains the most vitamin C among fruits, to improve skin immunity, regenerate damaged skin, and aid recovery. , In particular, skin whitening is possible with large amounts of vitamin C.

Next, brown algae extract may be included in the composition.

The brown algae included in the brown algae extract of the example may be seaweed such as seaweed, hijiki, kelp, or seaweed, and these brown algae contain a lot of fucoidan.

Fucoidan is a polysaccharide whose main ingredient is fucose, and has sticky properties. This sticky component has excellent properties for activating immunity, allergies, and cell regeneration, and these properties are used in this example. .

These properties of brown algae extract are due to the sulfate group contained in fucoidan, and can be effective in maintaining skin elasticity through rapid regeneration of damaged skin cells.

In this embodiment, the composition is sprayed in a spray form, allowing the user to achieve a skin care effect such as a mask pack through simple spraying. Even with the same spraying force, the composition fine particles are sprayed over a wider surface area using a fluorescent spray. Carbon-based surfactants make up the composition.

In particular, by utilizing the low surface tension characteristic of the fluorocarbon-based surfactant, the composition is sprayed evenly over a wide area when sprayed.

Figure 2 is a diagram for explaining the spraying force, the surface tension of the pack, and the surface area of the pack when spraying.

The force required to spray the pack composition is made up of the product of the surface tension of the pack and the increased surface area of the pack after spraying. That is, as shown in Equation 1 below, even if the same force is applied, the lower the surface tension of the sprayed composition (pack), the larger the surface area the composition can be sprayed after spraying.

In this example, a fluorocarbon-based surfactant is contained to ensure that the surface tension of the composition (pack) is low.

The surfactant used in this example is CF ₃ (CF ₂ ) _5-9 SO ₄ Na, CF ₃ (CF ₂ ) _5-9 SO ₄ K, CF ₃ (CF ₂ ) _5-9 SO ₄ NH _4, Any one or a mixture of two or more selected from CF ₃ (CF ₂ ) _5-9 SO ₃ Na, CF ₃ (CF ₂ ) _5-9 SO ₃ K, and CF ₃ (CF ₂ ) _5-9 SO ₃ NH ₄ It can be used.

In this example, the composition, which is the material that makes up the spray pack, contains a fluorocarbon surfactant, and has a superior surface tension lowering ability compared to the hydrocarbon surfactant previously used for skin care. It has excellent foaming power, dispersion power, and spreadability.

Hydrocarbon-based surfactants lower the surface tension in aqueous solutions to about 35.0 dyn/cm, but in contrast, fluorocarbon-based surfactants can lower it to 15.0 dyn/cm, so the composition can be sprayed through a spray pack through the lowered surface tension. Since it can be sprayed over a large surface area, the effect of being able to spray very small droplets can be achieved.

Figure 3 is a photograph of a comparison experiment between a hydrocarbon-based surfactant and a fluorocarbon-based surfactant to confirm the surface area when spraying water.

Figure 3(a) shows a water spray experiment using a hydrocarbon-based surfactant, and Figure 3(b) shows a water spray experiment using a fluorocarbon-based surfactant.

The exact difference in surface area can be determined through further specific experiments, but depending on the difference/ratio of surface tension, it can be predicted that the surface area will be approximately 2.3 times larger when a fluorocarbon-based surfactant is used.

The inventor of the present invention prepared a spray pack composition containing a fluorocarbon-based surfactant while varying the types of extracts as shown below, and sprayed the composition on the face for skin care with a composition consisting of these substances to form a mask pack. An experiment was also conducted using the mask pack (see Figure 4). That is, the existing mask pack had to be taken out by hand and then applied directly to the face, but in the present examples, the composition was applied to a large surface area by simply spraying it on the face in the form of a spray. As this is sprayed, a thin film may form on the skin.

It was sprayed on the skin of the hand, and the white part indicates the formation of a film by polyvinyl alcohol.

Example 1

In Example 1, moss extract was used for moisturizing effect, polyvinyl alcohol played a role in forming a film on the skin for use as a mask pack, and propylene glycol was used at 1.0% for sterilizing effect. It may be contained in wt% or less. In addition, Ammonium C9-10 perfluoroalkylsulfonate, a fluorocarbon surfactant, was included, and some substances such as ethanol, tensol, and perfume were included to provide a refreshing feeling when in contact with the skin.

Example 2

In Example 2, it was prepared using Kakadu plum extract instead of moss extract as an additive for whitening effect.

Example 3

In the case of Example 3, brown algae extract was contained as a material for moisturizing effect, and a fluorocarbon-based surfactant was used together as in the previous example.

Hydrocarbon-based surfactants, which are added to existing spray packs to improve sprayability, have a critical micelle concentration (CMC) of 0.05 - 0.1 wt%, and are sprayed with a surface tension of 35 dyn/cm above the critical micelle concentration. There were limits to improving the sprayability of the pack.

However, the critical micelle concentration of fluorocarbon-based surfactants is about 1/2 of that of hydrocarbon-based surfactants, so it is 0.025-0.05 wt%. Even above the critical micelle concentration, the surface tension can be lowered to less than 20 dyn/cm, which is low in spray packs. Spraying is possible even under pressure, and the usability of the product was improved by reducing the liquid size of the sprayed particles.

In addition, even if the concentration of the surfactant increases above the critical micelle concentration, the surface tension of the product remains constant, so there is no need to add more than the critical micelle concentration. Considering this critical micelle concentration, the amount of fluorocarbon-based surfactant is It is desirable to ensure that the content does not exceed 5.0 wt%, that is, 5.0 wt% or less.

In addition, for skin care, it is preferable that compositions such as moss extract, kakadu extract, and seaweed extract are included in the range of 0.05 to 5 wt%. If the content is less than 0.05 wt%, the effect on the skin is very weak, and 5 wt% If the percentage is exceeded, it is difficult to obtain the same effect and the cost also increases significantly, which is not desirable.
