Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a lubricating agent for condoms and a condom to which the agent is attached. More specifically, the present invention relates to a lubricating agent for a condom, which is made of squalene, a partial hydrogenated product thereof, squalane, or a mixture thereof, is safe to the human body, has high performance, and a condom to which the agent is attached.

[0002]

2. Description of the Related Art Conventionally, as a lubricating agent for condoms,
Silicone oils and the like have been used. However, in recent years, the toxicity of silicone oil to the human body has been highlighted, and its use in the human body has been avoided. In particular, the penetration of silicone oil from the wound into the body is a problem. For example, when silicone oil enters the body, it may not be digested and may accumulate in blood vessels and the like.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a condom-lubricating agent which is safe for the human body and which can obtain a proper lubrication effect during use and a condom to which the agent is attached. Is provided.

[0004]

Under the above conditions, the present inventor has conducted extensive studies and, as a result, found that the above problem can be solved by using a specific compound, and thus the present invention has been accomplished.

That is, the present invention provides a condom lubricating agent comprising one or more compounds selected from the group consisting of squalene, a partial hydrogenated product thereof, and squalane, and
It is a condom to which the lubricating agent for a condom is attached.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is a lubricant for condoms, which comprises squalene, a partial hydrogenated product thereof, squalane or a mixture thereof.

Squalene (SQUA used in the present invention
LENE) is the following general formula

Embedded image Is a polyunsaturated compound represented by.

Since the above compounds are contained in trace amounts in vegetable oils such as olive oil, rice bran oil and corn oil, and various animal and plant raw materials such as animal oils such as chicken, pork and general fish, as well as the human body, they should be collected and used from them. You can However, since it is contained in large amounts in the liver oils of deep-sea sharks such as sharks, sharks, sharks, and common sharks, it is preferable to collect and use them. Further, although synthetic squalene synthesized from isoprene and the like can be used, natural squalene derived from plants and animals is preferable.

The squalane used in the present invention is a completely hydrogenated product of the above squalene. Squalane has been found in the living body, and it is said that, like squalene, squalane can also be regarded as a biological reaction product. When using squalane in the present invention, it is desirable to use a completely hydrogenated natural squalene. In addition, a partially hydrogenated product of squalene, preferably natural squalene, can be used in the present invention.
Further, the lubricating agent of the present invention is disclosed in JP-A-1-263193.
It may be squalene, squalane, or the like which has undergone a phase transition by a magnetic field as described in Japanese Patent Laid-Open Publication No. 2003-242242. These three kinds of compounds may be appropriately mixed and used.

The above-mentioned hydrogenated substance can be obtained by hydrogenating in a conventional manner with a metal catalyst composed of platinum, platinum, cobalt, molybdenum, nickel or a mixture thereof. Especially iodine value (g / 10
Those having 0 g) of 3.5 or less are preferable because of high oxidative stability.

Also, these squalene and squalane are
It is said to be rapidly absorbed, digested and metabolized in the body. Therefore, even if squalene, squalane, etc. enter the body through mucous membranes, scratches, etc., they are absorbed and digested, so there is no problem of accumulation. Squalene, squalane used in the present invention,
The partial hydrogenated product of squalene is a substance existing in the living body, and thus is harmless to the human body.

The lubricating agents of the present invention include palm oil, olive oil, sesame oil, horse oil, jojoba oil, eicosapentaenoic acid, docosahexaenoic acid, cholesterol, cholesterol fatty acid ester, and lysophospholipid, within the scope of the present invention. Kinds; Polyisoprene rubber, natural rubber; Vitamin E; Lecithin; Hydrogenated products of oligomers of ethylene, propylene, butene, isobutylene, decene; Polyvinyl alcohol; Vaseline; Viscosity modifiers such as glycerin; Antioxidants; Extenders; Chitin Antibacterial agents such as chitosan, antiseptics, spermicides, antiphlogistics, surfactants and the like can be added. All of these additives are preferably oil-soluble additives. These additives can generally be added up to the same amount by weight as squalene, its partial hydrogenates, squalane or mixtures thereof.

In addition, fine powders of polyethylene, polystyrene, polymethylmethacrylate, polyvinylacetate, and a copolymer of monomers constituting these may be blended with the lubricating agent of the present invention. Further, the lubricating agent of the present invention may be used by being wrapped in a substance such as cyclodextrin.

Further, the present invention is a condom to which the above-mentioned lubricating agent is attached. As a condom that can be used,
Natural rubber latex condom; SBR latex,
A synthetic rubber condom such as polyurethane rubber; a collagen condom; or a plastic condom can be used. These condoms may have the surface treated with radiation, ozone, plasma, electron beam, or the like, or may have a monomer added to the surface to improve retention of the lubricating agent.

Any method may be used to attach the above-mentioned lubricating agent to the condom. The lubricating agent of the present invention may be sprayed toward the condom or may be immersed in the lubricating agent. Alternatively, it may be applied with a brush or the like. Usually, it is desirable to attach the lubricating agent of the present invention to both sides of a condom. The lubricating agent of the present invention is preferably uniformly attached to the whole in an amount of 0.05 to 20 cc per condom.

EXAMPLES The present invention will be described below with reference to examples. In the examples, natural rubber latex condoms and polyether-based polyurethane rubber condoms were manufactured, and the following lubricating agents were applied thereto by coating. For comparison, a silicone oil having the same condom as above was prepared.

25 male monitors were used, and the following answers were sought after use. Answers are better than those using silicone oil (conventional product) A: The feeling of use and wearing are better than those of the conventional product B: The feeling of use and wearing are the same as those of the conventional product C: Conventional product There are three types, one with better usability and wearing feeling.
