Description
Technical Field
The present invention relates to a cosmetic, and more particularly, to a two-layer type cosmetic in which an oil layer is separated from a water layer.
Background
In recent years, cosmetics are required not only for their properties but also for their aesthetic appearance and high design level, wherein two-layer type cosmetics in which an oil phase and a water phase are separated have a unique aesthetic appearance and excellent properties.
Two-layer type cosmetics have been used in various forms in products such as makeup removers and hair flower cosmetics, and for example, patent document 1 (Japanese patent application laid-open No. 2002-509556) discloses a two-phase type hair cosmetic containing a water-soluble polymer compound and polyether quaternary polysiloxane in an aqueous phase and pentaerythritol tetrakis (ethyl hexanoate) in an oil phase. In addition, patent document 2 (japanese patent application laid-open No. 2016-050184) discloses a two-phase liquid cosmetic containing a film-forming agent such as polyvinylpyrrolidone as a separating agent.
Further, patent document 3 (japanese patent application laid-open No. 2018-058829) discloses that a multilayered cosmetic having two or more layers is effective even when an active ingredient of a carotenoid is used as a stabilizer.
Such two-layer type cosmetics, in which an oil phase is usually disposed on the upper layer and a water phase is disposed on the lower layer, are uniformly mixed after shaking or vibrating, and then are applied to the skin. Two-layer cosmetics are known for their moisturizing effect of oil agents and water-soluble moisturizing effect of aqueous agents, light skin feel, and good permeability.
As mentioned above, two-layer cosmetics generally have an oil phase on top and a water phase on bottom, and are quite similar and indistinguishable in appearance regardless of the product, and are not different from the external aesthetic appearance of the product.
Disclosure of Invention
The present invention has been made in view of the above-mentioned disadvantages of the prior art, and an object of the present invention is to provide a two-layer type cosmetic having oil layers of different shapes and separated from a water layer, which has an aesthetically pleasing appearance.
The technical scheme of the invention is realized as follows: a two-layer type cosmetic having an oil layer separated from an aqueous layer, comprising an oil layer and an aqueous layer separated from each other, characterized in that the oil layer exhibits one or more layers composed of spheres.
In an ideal form, the oil layer is a sedimentation layer and is positioned at the bottom of the container.
Oil is often located at the upper layer in a two-layer type cosmetic because of its low specific gravity compared to water, but if the oil layer is located at the uppermost layer, the cap portion of the container will block the oil layer to be invisible, and thus the appearance is not ideal.
The oil layer is positioned at the lower layer after being settled, is spherical, can be completely visually confirmed, and is more attractive.
In an ideal embodiment of the present invention, the specific gravity of the material constituting the oil layer at 25 ℃ is slightly larger than the specific gravity of the material constituting the water layer at 25 ℃ as well.
If the specific gravity value of the material constituting the oil layer at 25 ℃ is larger than that of the material constituting the water layer, the oil layer is likely to settle.
In an ideal embodiment of the present invention, the difference in specific gravity between the material constituting the oil layer and the material constituting the water layer at 25 ℃ is 0.001 or more.
When the difference in specific gravity between the material constituting the oil layer and the material constituting the water layer at 25 ℃ is in the above range, the oil layer can be settled and the oil layer can be kept stable in a spherical state.
In an ideal embodiment of the present invention, the substance constituting the oil layer contains an amphipathic oil agent, and the amphipathic oil agent is more favorable for settling of the oil layer and for maintaining the stability of the spherical shape of the oil layer.
In a preferred embodiment of the present invention, the oil layer or the water layer is transparent or translucent.
In an ideal embodiment of the present invention, the oil layer and the water layer are formed in different colors.
In addition, in order to solve the technical problems, the cosmetic needs to be filled in a transparent or semitransparent container; when the two-layer type cosmetic is filled in the container, the water layer and the oil layer are separated in a standing state, and after the container is shaken up and down, the water layer or the oil layer is uniformly mixed; and standing again, separating the water layer from the oil layer, recovering the oil layer into a spherical oil layer, and settling at the bottom of the container.
By adopting the technical scheme, the product can be in a uniformly mixed state only by shaking up and down when in use, and the unique appearance can be seen before and after use. Meanwhile, the two-layered type cosmetic of the present invention is a cosmetic filled in a transparent or translucent container, and has aesthetic appearance.
Drawings
The invention will be further described in detail with reference to examples of embodiments shown in the drawings to which, however, the invention is not restricted.
FIG. 1 shows a two-layer type cosmetic in a still state, which was prepared in accordance with example 1. (a) The oil layer is single, and (b) the oil layer is multiple.
FIG. 2 shows a two-layered cosmetic composition prepared by shaking up and down according to example 1.
FIG. 3 shows the appearance of a two-layer type cosmetic composition when (a) it was left to stand for 10 minutes, (b) it was left to stand for 30 minutes, and (c) it was left to stand for 60 minutes after shaking up and down in accordance with example 1.
Detailed Description
The two-layer type cosmetic with separated oil layer and water layer comprises the oil layer and the water layer which are separated from each other, wherein the oil layer presents one or more layers composed of spheres.
Hereinafter, when the cosmetic is separated into two layers, all components contained in the oil layer are referred to as "oil layer-constituting substances", and all components contained in the water layer are referred to as "water layer-constituting substances".
Next, all components contained in the oil-layer-constituting substance are referred to as "oil-layer components", and all components contained in the water-layer-constituting substance are referred to as "water-layer components".
In the present invention, the specific gravity difference between the oil layer-forming substance and the water layer-forming substance at a product temperature of 25 ℃ is 0.001 or more, and the specific gravity of the oil layer-forming substance is greater than that of the water layer-forming substance. The difference in specific gravity between the oil layer-forming substance and the water layer-forming substance is more preferably 0.005 or more, and most preferably 0.007 or more.
In the present invention, the specific gravity of the oil layer-forming substance at a product temperature of 25 ℃ is preferably 0.900 or more, more preferably 0.920 or more, and most preferably 0.950 or more.
In the present invention, the specific gravity of the material constituting the water layer at a product temperature of 25 ℃ is preferably 0.900 or more, and more preferably 0.920 or more.
In the present invention, the specific gravity of the oil layer-constituting substance at 25 ℃ must be slightly greater than the specific gravity of the water layer-constituting substance at 25 ℃.
Meanwhile, the specific gravity of the materials constituting the oil layer or the water layer may vary with the temperature. Since the specific gravity of the oil layer-forming substance changes more than that of the water layer-forming substance, the specific gravity of the oil layer-forming substance and that of the water layer-forming substance are reversed, and the oil layer that has settled on the bottom of the container sometimes floats to the upper layer, which is an aspect of the present invention.
In an ideal form of the invention, the specific gravity of the material forming the oil layer at 25 ℃ is greater than the specific gravity of the material forming the water layer at 25 ℃.
With such a structure, when a two-layer type cosmetic is used, a spherical oil layer is deposited on the bottom of the container, and the appearance is very beautiful.
In the present invention, the mass ratio of the oil layer-constituting substance to the water layer-constituting substance is not limited, but is preferably 1:99 to 30:70, more preferably 2:98 to 20:80.
The two-layer cosmetic of the present invention can be prepared by mixing predetermined components in appropriate amounts. For example, the following oil layer-forming substance and water layer-forming substance may be prepared separately and then the two substances may be mixed.
The present invention is a cosmetic in which the above two-layer type cosmetic is filled in a transparent or translucent bottle container.
The cosmetic filled in the container according to the present invention is allowed to stand to separate an oil layer from a water layer, and the oil layer is present in a spherical form.
When the cosmetic filled in the container is used, the oil layer and the water layer can be uniformly mixed only by shaking up and down. After use, the oil layer and the water layer can be separated again only by standing for a period of time, and the oil layer can be spherically settled at the bottom of the container. Upon standing after shaking, a plurality of small spherical oil layers appear, and over time, these small spherical oil layers combine together to form a large spherical oil layer.
The size of the spherical oil layer varies depending on the volume of oil layer added. Filling the mass ratio of the oil layer forming substance to the water layer forming substance in a range of 2:98-20:80 into a 25ml screw bottle, wherein when the oil layer forms a large sphere, the diameter of the oil layer is about 0.2-1.2cm.
The oil layers are combined after the oil layers are contacted with each other, and if the bottom area of the container is large, when each oil layer of the oil layers cannot be contacted, the oil layers can be stably settled at the bottom of the container.
That is, the diameter of the spherical shape of the oil layer in the static state can be controlled according to the bottom area of the cosmetic container. For example, when it is desired to obtain the effect of containing a plurality of small spherical oil layers, a container having a large floor area can be used; conversely, when a large layer of spherical oil is desired, a container having a small floor area can be used.
The cosmetic can be applied to skin care cosmetics such as toner, emulsion, beauty essence and the like, nail care products such as nail polish and hair care cosmetics such as hair care products and hair oil and can also be applied to body emulsion cosmetics.

Two-layer cosmetics were prepared according to the formulation shown in table 1 below, i.e., the water layer component substance a and the oil layer component substance B were mixed together at room temperature, and then the water layer component substance a and the oil layer component substance B were mixed together, and then the mixture was mixed together at a certain ratio and filled into 25ml screw bottles to prepare five types of cosmetic products according to examples 1 to 3 and comparative examples 1 to 2. The numerical values in table 1 are the content ratios of the respective components by mass with respect to the total amount of the two-layer type cosmetic. Example 1 the appearance of the sample when it was left standing was as shown in FIG. 1, and the appearance after shaking up and down was as shown in FIG. 2.
[ TABLE 1 ]
< test example 2> evaluation of appearance of two-layer type cosmetic
The appearance and oil layer shape of the two-layer type cosmetics of examples 1 to 3 and comparative examples 1 to 2 in table 1 were evaluated, and the appearance of the solution immediately after mixing, after mixing and standing for 60 minutes and after mixing and standing for 3 days, and the oil layer shape after mixing and standing for 60 minutes and after mixing and standing for 3 days were observed, and the results are shown in table 2.
[ TABLE 2 ]
Examples 1 to 3, immediately after mixing, were observed to give a slightly turbid, homogeneous solution, which became clear after standing, and the transparency of the solution was also increased. However, comparative examples 1 and 2 were turbid even when they were left to stand after mixing, and comparative example 2 maintained the emulsified state.
The oil layers of examples 1-3 were spherical and the lower layer was to the bottom of the vessel, but the oil layers of comparative examples 1 and 2 did not become spherical, but layered and floated on the top of the water layer.
< test example 3> recovery of spherical oil layer
After shaking the two-layer type cosmetic of example 1 up and down, the water layer and the oil layer were uniformly mixed, and thereafter the container was left standing for a while to observe the spherical recovery of the oil layer of FIG. 3.
As shown in fig. 3, after the two-layer type cosmetic of example 1 was shaken up and down, a plurality of small spherical oil layers were observed after standing for 10 minutes, and after standing for 30 minutes, the small spherical oil layers were combined into a slightly larger spherical shape due to contact with each other, and further, after standing for one hour, they were combined into several larger spherical oil layers.
From the above results, it was found that the two-layer type cosmetic filled in the container of the present invention can be separated from the oil layer after standing for a while and the oil layer can be recovered into a spherical shape even when the water layer and the oil layer are mixed by shaking. And the pleasure of enjoying beautiful appearance can be obtained before and after the product is used.
