DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid base material which is separated into multiple layers, and more specifically, a cosmetic product which is uniformly mixed when shaken, but is quickly separated into multiple layers when left standing. The present invention relates to a multi-layer separated liquid substrate that can be used as a substrate for pharmaceuticals, fragrances, insect repellents, agricultural chemicals, display toys, and the like.

[0002]

2. Description of the Related Art A liquid material separated into multiple layers has the feeling of use of each layer component, the effect and characteristics of a drug or coloring agent dissolved in each layer component, and is strongly appealing to the sight. It has a unique feature in appearance, and is known to be divided into two layers and three layers.

[0003] The two-layer and three-layer components may be separated from each other by appropriately combining an immiscible oil layer component, an aqueous layer component and an alcohol layer component, or two or more insoluble oil components. There are, for example, those obtained by appropriately combining an aqueous layer component or an alcohol layer component.

[0004] However, these multi-layer separated liquids are mixed by shaking, but it is difficult to separate them into multi-layers immediately after standing, and it takes a long time to exhibit the original neat layered state. Unique features are halved.

[0005] In order to prevent the unique features of the appearance from being impaired, it has been proposed to be able to quickly separate and return to the original state after shaking.
Japanese Patent Application No. 3-80856 (Japanese Unexamined Patent Application Publication No.
As described in Japanese Patent Publication No. 10 (1994), a liquid composed of an oil layer component such as a liquid oil and an aqueous layer component such as a wetting agent has the following formula (where RCOO is a fatty acid obtained by removing hydrogen of a carboxyl group from a fatty acid). Three-layer type containing one or two or more selected from the group of surfactants represented by the following formula: C6 to C22, X + Y + Z represents an average addition mole number of ethylene oxide of 1 to 10). Bases are known.

However, Japanese Patent Application No. Hei.
Means described in -80856 can be separated into three layers, but separated into more layers, for example, a very unique appearance which has been separated into four layers which has never been seen before to further enhance the visual effect. However, since it is not interesting in terms of novelty, it is expected to appear in four or more layers at an early stage.

[0007]

SUMMARY OF THE INVENTION The present invention is intended to solve such a problem, and the object can be achieved by completing the invention described below. That is, the present invention focuses on various properties of silicone oil that can be used as an oil layer component,
In addition to simply using a silicone oil that does not mix with a humectant, a surfactant, or another oil layer component as an aqueous layer component, even when two or more types of silicon oil are used as an oil layer component, a silicone oil is used. By using silicone oil that does not mix with each other, it can be separated into four layers neatly and quickly separated after shaking so that it returns to its original state.

[0010] The invention of the present application is a method in which the silicone oil is dimethyl silicone oil and has a viscosity of 5c.
It may be one having s (centistokes) or more. At this time, if the viscosity of the silicone oil is 5 cs or less even with methylphenyl silicone oil or the same type of dimethyl silicone oil, the compatibility is good when liquid paraffin is present as the liquid oil component, and the silicone oil is not separated, which is not preferable. . In addition, the silicone oil is used as one of the liquid oil components to be used in combination with the silicone oil as the third layer as described above, separately from the silicone oil as the third layer in the present invention. However, they cannot be used as one of the liquid oil components because they have good compatibility even if they have different viscosities. Therefore, when the silicone oil as the third layer in the present invention is dimethyl silicone oil having a viscosity of 5 cs or more, one of the liquid oil components to be used in combination is 5
It is not possible to use dimethyl silicone oil having a viscosity of cs or less.

Either an ethylene) siloxane polymer or a dimethylsiloxane methyl (polyoxyethylene) siloxane methyl (polyoxypropylene) siloxane polymer may be used.

At this time, the viscosity of the dimethyl silicone oil is 5 cs (centistokes) or more, and the dimethylsiloxane methyl (polyoxyethylene) siloxane polymer has a weight percent of polyoxyethylene of 4%.
It is also 0 or more (8 or more in HLB conversion). That is, a silicone oil obtained by using dimethyl silicone oil and a polyether-modified silicone oil is combined with a dimethyl silicone oil having a viscosity of 5 cs or more and a dimethyl siloxane methyl (polyoxyethylene) having a weight percent of polyoxyethylene of 40 or more. The polyether modified silicone oil may be used in combination with either an ethylene) siloxane polymer or a dimethylsiloxane methyl (polyoxyethylene) siloxane methyl (polyoxypropylene) siloxane polymer.

The present invention also provides a water-soluble and / or oil-soluble coloring agent, a water-soluble and / or oil-soluble drug, and a fragrance, each alone or in combination. . At this time, it is preferable that vitamins are included as the medicine.

Further, the invention of the present application is such that the above-mentioned four layers are separated into five layers by adding mercury.
