Description

METHOD FOR ABSORBING OF LIQUID STATE COSMETICS < RTI ID = 0.0 >

The present invention relates to a method of absorbing liquid contents, and more particularly, to a method of absorbing liquid contents in which the contents are absorbed into an absorbent by applying shearing stress to a liquid content and an absorbent together.

There is a kind that viscous contents of cosmetics including ultraviolet ray shielding function are absorbed by an absorbent material such as a sponge. Here, the process of absorbing the contents is as follows. When the absorbent material is inserted into the fact container and sprayed by the spray method, the contents are put into the fact container, and the absorbent material is put into the fact container and then pressed several times with the press to naturally absorb the contents into the absorbent material. This process proceeds to an automated process. Therefore, the confirmation of whether or not the absorbent material is sufficiently absorbed is only an apparent confirmation. This confirmation may not be meaningful when absorbing a particularly high content of content. In addition, there is a conventional mechanical spraying or pressing method, but the contents of a high viscosity formulation have a problem that the pores of the absorbing material are small or can not be absorbed well because of the area area characteristics.

If the content of the high viscosity is not sufficiently absorbed by the absorbent material, bubbles may be generated or sufficient contents may not be absorbed by the absorbent material, so that the absorbent material and the absorptive material may not be properly puffed.

In order to solve the above-mentioned problems, the present invention is a method of absorbing liquid contents and an absorbent material into a container and kneading them by applying a shear stress at an angle of 20 to 80 degrees to easily absorb the contents of a high viscosity, It is an object of the present invention to provide a method of absorbing a liquid content capable of efficient absorption.

In order to solve the above-mentioned problems, the present invention provides a method of absorbing liquid contents, which comprises kneading a liquid content and an absorbing material into a container and applying a shear stress at an angle of 20 to 80 degrees.

In one embodiment of the present invention, the dough may be applied by applying shear stress while holding both sides of the container containing the liquid contents and the absorbent material by rotating the liquid in the left or right or upside down direction.

In one embodiment of the present invention, the container may have a thickness of 50 to 5000 mu m.

Hereinafter, preferred embodiments of the present invention will be described in detail in order to facilitate the present invention by those skilled in the art.

The present invention provides a method of absorbing liquid contents, which comprises kneading a liquid content and an absorbing material into a container and applying a shear stress at an angle of 20 to 80 degrees.

In the present invention, the shearing stress applying tool is not particularly limited, but may include a hand, a manual instrument (machine), and an automatic instrument (machine).

The absorbing material (carrier) used in the present invention is not particularly limited in terms of the material or pore size. Polyolefin foam, polyester foam, polyether foam, polyurethane foam, cotton, nonwoven fabric, acrylonitrile-butadiene rubber (NBR), styrene butadiene rubber (SBR) , Natural rubber (NR), polyvinyl chloride, polyethylene, EVA (Ethylene Vinyl Acetate), latex, silicone, film type, SIS (Styrene Isoprene Styrene), SEBS (Styrene Ethylene Butylene Styrene), PVA Elastomer, nitrile, butyl and neoprene, a dry urethane, a wet urethane and the like, preferably a sponge.

In the present invention, it is preferable to put the above absorbent material into 10 to 200 containers. The absorbent material may contain 10 ml to 50 ml of the liquid content per one. Therefore, the amount of the liquid content in the container is preferably 100 ml to 10 L, more preferably 1 to 5 L. When the content of the liquid in the container is more than 10 L, it is difficult for the contents to be adsorbed uniformly by one hand and a shear stress is applied to the container. In addition, it is not easy to confirm the uniformity of contents adsorption when working over 10L. Below 100 mL, the productivity is inefficient and very inefficient. The more the amount is, the more difficult it is to work. In the present invention, the absorber is filled about 1.5 times more than the general filler content, in order to maximize the physical friction.

The liquid content used in the present invention is not particularly limited as long as it is a liquid content. For example, it may be a liquid content of a skin lotion, a skin softener, a skin toner, an astringent, a lotion, a milk lotion, a moisturizing lotion, a nutrition lotion, a massage cream, have. Preferably, it may be an ultraviolet screening agent (sun block) of the formulation.

The liquid content may be an aqueous dispersion type, an oil dispersion type, a w / o type or an oil-in-water (O / W) type.

In addition, the liquid content is not limited in its viscosity, and has a very wide range of viscosity, so that various liquid contents can be used. Preferably a liquid cosmetic having a viscosity of 20,000 cps or less, specifically 15,000 cps or less, more specifically 5,000 to 12,000 cps, or 1 to 5,000 cps, more specifically 8,000 to 11,000 cps or 1 to 3,000 cps . The present invention can provide an efficient absorption method for carrying such liquid contents by hand to the absorbing material. Therefore, it is possible to use various kinds of absorbers having various materials, pore size, hardness, number of pores, density, elongation percentage, bulk absorption rate, absorption rate, absorption property and the like. Therefore, the choice of absorbent materials and contents, which were previously limited, is widening.

The viscosity of the liquid content can be measured with a viscosity measuring instrument, for example, LVDV II + PRO or RVDV III ULTRA, spindle NO. 63 or spindle NO. 64, speed 5 RPM or 12 RPM, but is not limited thereto.

In the present invention, the container is used to provide a specific space for mixing the contents and the absorber, and a flexible thermoplastic resin is used. The container preferably has a thickness of 50 to 500 mu m. When the thickness is less than 50 mu m, the container may be easily broken if a shearing force is strongly applied, and when the thickness is more than 500 mu m, it becomes too thick and it is difficult to impart a proper shearing force.

The container is not particularly limited as long as it has the above-mentioned thickness and is capable of kneading an inner material from the outside, but it is preferable that the container is made of polyvinyl alcohol (PVA), polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE) Vinyl, and may be vinyl, preferably vinyl.

After the liquid contents and the absorbent are put together into the container, the inside air of the container is removed as much as possible and sealed. Thereafter, the liquid content and the absorbent material in the container are kneaded together.

The present invention maximizes physical friction in order to raise the absorbent capacity of the absorbent to the maximum level. For this purpose, shear stress is applied, and preferably shear stress is applied at an angle of 20 to 80 degrees. More preferably from 30 to 70 degrees, and most preferably from 40 to 60 degrees. If it is less than 20 degrees, the force to apply the shear stress becomes insufficient. If it is more than 80 degrees, the work operation of the worker becomes very difficult, so that it is difficult to perform the work of applying the shear stress and the compressive force is transmitted rather than the shear force Because.

The dough may be applied on the container containing the liquid content and the absorbent material along the direction of shear by hand. Alternatively, it is possible to hold both sides of the container containing the liquid content and the absorbent material, and to apply shear stress by rotating the container in the opposite direction to the left or right or upward and downward. Shear force can be applied when rotating in the left-right or up-and-down direction. The application of shear stress angles can be applied in horizontal and vertical ratios in the volume containing the absorber and contents in the container. For example, when the height of the absorber and contents in the container is 50 cm, if 50 cm is horizontally pushed, a shear stress of 45 is generated.

The dough is preferably repeated 5 to 15 times. This dough processing removes air from the absorber and allows the contents to be absorbed optimally by the absorber. By this shear dough absorption process, any type of absorbent material of any viscosity, and any type of absorbent material can be quickly and effectively absorbed into the absorbent material.

When the dough is finished, it is checked whether the absorbent material is sufficiently absorbed. Thereafter, the absorbent material, in which the contents are sufficiently absorbed, is moved to the tray and is transported to the container. If you need to calibrate the contents through weighing, you can fill the contents.

The method for absorbing liquid contents according to the present invention is more effective than the conventional mechanical spray or compression method, capable of absorbing highly viscous contents. There is an advantage.

Hereinafter, the configuration and effects of the present invention will be described in more detail with reference to Examples, Comparative Examples and Experimental Examples. However, the following Examples, Comparative Examples and Experimental Examples are provided only for the purpose of illustration in order to facilitate understanding of the present invention, and the scope and scope of the present invention are not limited thereto.

[Experimental Example 1] Experimental study on degree of absorption of liquid contents according to angle of shear stress

Shear stress was applied at 0, 10, 20, 30, 45, and 80 degrees with the liquid content to be impregnated in the sponge to compare the degree of absorption of the liquid contents to the sponge. In the shear test method, as shown in FIG. 2, a sponge (absorbent material) was put in a state in which 10 g of liquid content was discharged between two glass plates, and the glass plate was pressed on the sponge to impregnate the contents. At this time, shear force was given by pushing the upper and lower glass plates in a staggered manner, and the angles of shearing were calculated by calculating the shear angle of shear stress. The results are shown in Fig.

As can be seen from FIG. 2, when the shear was applied at 0 degree and 10 degrees, the content impregnation did not become uniform throughout the sponge, and shear stress of 20 to 30 degrees or more was applied to uniformly impregnate the contents into the sponge. It was found that the impregnation amount of the contents was less than 4.7 g when the content was 0 ° C and less than 5.1 ~ 6.4g when the shear stress was 20 ° C or more and 80 ° C or less. It was found that the contents were most uniformly impregnated and impregnated most at 45 degrees. If the angle of the shear stress exceeds 80 degrees, the amount of the contents to be impregnated is rather reduced.
