In summer, we mainly choose waterproof (that is, waterproof) eye pencil cosmetics to prevent the makeup from being ruined by sweat or water in a pool or the like.

Normally, eye pencil cosmetics are easy to bleed in water due to the principle that water forms a water-soluble moisture film that wraps oil in the form of 'oil in water', but waterproof eye pencil cosmetics are 'water in water'. Oil forms a film in the form of 'water in oil', which makes it difficult for water and sweat to bleed through.

Such conventional waterproof eye pencil cosmetics have a short waterproofness against sweat and water, and since they are reapplied every 2 to 3 hours, they do not give a refreshing feeling, feel heavy in use, and have poor spreadability. Therefore, there was a problem that the volume decreased.

In addition, the skin around the eyes does not have the function and flexibility to protect the skin around the eyes, and there is no ingredient that supplies nutrients, so the skin around the eyes tends to fall off. There was a problem that it was easy to wake up.

[Method for producing natural waterproof eye pencil cosmetics]
Natural waterproof eye pencil cosmetic compositions of Examples 1 to 3 were prepared with the compositions (unit: weight %) shown in Table 1 below.
Batch Reactor 10, which will be described next, is a device that mixes, disperses, and emulsifies the composition while heating or rotating.

The next described batch is the Batch Reactor 10, which is not filled or emptied while the reaction is taking place. As shown in FIG. 1, the batch reactor consists of a cylindrical drum-shaped body, and an obstacle plate is installed in the inner space of the body to generate friction in the vertical direction so that the composition can be uniformly and well mixed. 11 is formed in the vertical direction, below the obstruction plate is formed a circular impeller part 12 that rotates primarily so that the composition can be uniformly and well mixed at the bottom, below the circular impeller part, the composition is at the bottom A double-armed impeller 13 is formed for secondary rotation so that the materials can be mixed well and uniformly.

The linear velocity refers to the velocity of the circular impeller portion and the two-armed impeller portion, and is set to 32 m/s for high speed, 20 m/s for medium speed, and 10 m/s for low speed.

Also, the rpm suitable for the linear velocity according to the present invention is set through the following calculation process.
As an example, if the length of the two-armed impeller section is 0.6 m, the linear velocity is length*3.14* (rpm/60).
At this time, rpm is further calculated and set by (linear velocity*60)/((length=0.6)*3.14).

FIG. 2 is a flowchart showing a method for producing a natural waterproof eye pencil cosmetic using the natural waterproof eye pencil cosmetic composition according to the present invention.

First, isododecane, a volatile oil, and isostearyl alcohol, a natural solvent oil, are placed in a batch reactor and primary mixed at a linear velocity of 30 m/s to 40 m/s for 1.5 to 2.5 minutes. (S10).

Here, the reason for mixing for 1.5 minutes to 2.5 minutes is that it is difficult to mix for 1.5 minutes or less, so there are many cases where the layers are separated, and more than 2.5 minutes causes many bubbles. Because of the problem, it is allowed to mix for 1.5 to 2.5 minutes, most preferably 2 minutes.

At this time, natural solvent oil is added to the volatile oil according to the present invention and mixed to replace the toxic component of the existing eye pencil with a natural component, or to create a mixed composition, so that the skin around the eyes can be troubled even after long-term use. After use, it can be easily removed with an eye pencil remover at a speed 1.5 to 2 times faster than before.

Then, the mixed volatile oil, isododecane, and the natural solvent oil, isostearyl alcohol, was charged with a colorant, black iron oxide (CI 77499), and a thickener, polyglyceryl-3 polyricinoleate, at a rate of 30 m/s to 40 m/s. Secondary mixing is performed for 1.5 to 2.5 minutes at a linear speed (S20).

Here, the reason for mixing at a linear velocity of 30 m/s to 40 m/s is that at 30 m/s or less, the coloring power of the coloring agent decreases, and when mixing volatile oils, natural solvent oils, coloring agents, and thickeners, This is because there is a problem that it gathers like a lump, a difference occurs in the appearance color and the coating color at 40 m / s or more, and a problem of deterioration occurs at an internal temperature of 50 degrees or more. Mixing at a linear velocity of 40 m/s is most preferred.

Next, talc as a bulking agent and polyglyceryl-2 triisostearate as a surfactant are mixed three times and then heated to 83° C. to 87° C. (S30).

Next, when the temperature reaches 83° C. to 87° C., polyethylene and polyisobutene among the film-forming agents are added, and quaternary mixing is performed for 1.5 to 2.5 minutes at a linear speed of 25 m / s to 30 m / s ( S40).

Here, the reason for mixing at a linear velocity of 25 m/s to 30 m/s is that at 25 m/s or less, many bubbles are generated when the film-forming agent is mixed with the volatile oil, natural solvent oil, colorant, and thickener. At 40 m/s or more, there is a problem that chroma becomes high and discoloration occurs quickly. Therefore, it is most preferable to mix at a linear velocity of 25 m/s to 30 m/s.

Next, trimethylsiloxysilicate, which is a skin conditioning agent, is added and mixed for a fifth time at a linear velocity of 30 m/s to 40 m/s for 1.5 to 2.5 minutes (S50).

At this time, by adding a skin conditioning agent containing natural ingredients to the natural waterproof eye pencil cosmetic composition, it is possible to make the skin around the eyes soft and healthy, reduce skin loss around the eyes, and restore flexibility. can do.

Next, among preservatives, glyceryl caprylate and hinokitiol are added and six-fold mixed at a linear velocity of 30 m/s to 32 m/s for 1.5 to 2.5 minutes (S60).

Here, in the present invention, the preservative includes natural preservatives consisting of hinokitiol, which is an extract of Arhat, magnolol, which is a magnolia extract, and DF-100, which is a grapefruit extract. , When compared with existing products, it extends the freshness and distribution period of cosmetics, and maintains the antiviral, antifungal, non-toxic, antibacterial and antioxidant effects, while maintaining the skin around the eyes compared to existing products. It minimizes troubles or diseases that occur in the eye.

Next, titanium dioxide (CI 77891) and tin oxide (CI 77861), which are coloring agents that react with black iron oxide (CI 77499) charged in advance to form a midnight black color, are added at 30 m/s to 40 m/s. 7th mixing for 1.5 to 2.5 minutes at a linear speed of 1 (S70).

At this time, the viscosity of the composition is measured to check whether it matches the viscosity of natural waterproof eye pencil cosmetics.

Finally, after cooling the batch reactor to 30° C. and adjusting the mixing, the batch is poured into a suitable storage container to complete the natural waterproof eye pencil cosmetic product (S80).
At this time, the completed natural waterproof eye pencil cosmetics are manufactured in a liquid form.
