DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anhydrous foam cleaning and wiping agent, and more particularly to a quick-disintegrating anhydrous cleaning agent which is used by spraying on toilet paper or the like, does not need to be shaken at the time of use, and has excellent low-temperature stability. The present invention relates to a foam-like cleaning agent for peripheral parts such as an anus, urinary tract, and vulva.

[0002]

2. Description of the Related Art Hot water purifiers are used in some cases for cleaning and elimination after defecation and urination, during menstruation, etc. However, due to high equipment costs, they have not yet become widespread. Paper is used.

[0003] However, it is difficult to sufficiently clean the toilet using toilet paper, and the skin around the anus is stimulated by friction during use. Causes deterioration. In addition, after urination or during menstruation, frequent repetition of rubbing due to wiping stimulates the urinary organs and the skin around the vulva, which tends to cause various problems.

In order to solve such a problem, it has been proposed to use a toilet paper coated with a cleaning agent (JP-A-59-225111, JP-A-62-242611).
JP, JP-A 1-265019, JP-A 2-32011, etc.).

[0005] These cleansing and wiping agents make it easy to remove the excrement remaining after defecation and urination, at the time of menstruation, and after wiping the excretion with ordinary toilet paper, etc., as well as damage to the skin due to friction and pain during wiping. By applying it to the skin around the anus in advance of defecation, excretion is less likely to adhere to the skin during the next defecation, and it is easier to wipe off the excrement, thereby improving the anus and urology. It keeps the periphery of the vulva and the like clean, and can prevent hemorrhoids, rash, itching, and other symptoms from worsening.

[0006] By the way, the technology relating to aerosol preparations has been greatly advanced at present, and is widely used as household goods, cosmetics, pharmaceuticals, industrial goods and the like. The aerosols can be used as a stable foam, a quick break foam, a spray type (Mist type), etc., depending on a delicate combination of active ingredients such as a propellant, a solvent and a drug. It is divided into various dosage forms.

[0007] From the viewpoint of application fields of aerosols, stable foams are used for shaving foams and hair care products, and fast-disintegrating foams are used for shaving lotions and some external medicines. Of these, fast-disintegrating foams are particularly effective for topical bath aerosols, for example, because they do not disperse into the air as spray-type foams do, and can spread the administered product mechanically even when compared to stable foams. Therefore, it is useful for a wide range of uses, and is also applied to the above-mentioned cleaning and wiping agents (JP-A-63-68686 and JP-A-63-216816).

[0008]

However, conventional spray-type and fast-disintegrating foams have a problem that the amount of the sprayed solution permeating toilet paper and applied to the skin is small. In addition, although the amount of the stable foam applied to the skin is large, there is a problem that the foam remains even after application and stains underwear and the like.

[0009] Accordingly, an object of the present invention is to provide a skin cleansing and wiping agent which can apply a sufficient amount of a solution to the skin, does not stain underwear and the like, and has a high wiping protection effect. .

[0010]

Under such circumstances, the present inventors have conducted intensive studies and as a result, have found that the above-mentioned method can be achieved by filling oil and a propellant having a specific vapor pressure into an aerosol container provided with a specific injection device. Find that they can achieve their goals,
The present invention has been completed.

That is, the present invention comprises one or more oils selected from the group consisting of vegetable oils, animal oils and synthetic oils, and a propellant having a vapor pressure of 1.0 to 7.0 kg / cm ² (25 ° C.). The undiluted solution has a stem diameter of 0.20 to 0.32 mm and a housing diameter of 0.20 to 0.32 mm.
An anhydrous foam cleaning and wiping agent filled in an aerosol container equipped with a spout of 0 mm ² is provided.

The vegetable oils used in the present invention include olive oil, almond oil, jojoba oil, avocado oil, peanut oil, castor oil, coconut oil, palm oil, safflower oil, sunflower oil, cottonseed oil, hydrogenated coconut oil, and hardened palm oil. Oils and the like, and as animal oils, lanolin, turtle oil, beeswax, squalene, squalane, pristane, mink oil,
Whale wax, tallow, etc., as synthetic oils, liquid paraffin,
Fatty acid esters of glycerin, such as glycerin tri-2-ethylhexanoate, and silicone oil. In addition, higher fatty acids such as linoleic acid and linolenic acid,
Higher alcohols, their esters, silicone oils and the like can also be used. Of these, jojoba oil,
Squalane, fatty acid esters of glycerin, methylpolysiloxane and liquid paraffin are particularly preferred. These can be used alone or in combination of two or more.

The propellants used in the present invention include:
Those which are compatible with the above vegetable oils, animal oils and synthetic oils are preferred, and liquefied petroleum gas, Freon, dimethyl ether and the like are particularly preferred. These propellants preferably have a vapor pressure at 25 ° C. of 1.0 to 7.0 kg / cm ² , particularly preferably 4.5 to 6.5 kg / cm ² . If the vapor pressure is less than 1.0 kg / cm ² , good foam cannot be obtained, and if it exceeds 7.0 kg / cm ² , the foam scatters and good fast-disintegrating foam cannot be obtained.

The amount of the propellant in the anhydrous foam cleaning and wiping agent of the present invention is preferably 5 to 30% by weight, particularly preferably 10 to 20% by weight.

The anhydrous foam cleaning and wiping agent of the present invention is produced by blending the above-mentioned essential components and, if necessary, medicinal components such as a bactericide and an anti-inflammatory agent and a fragrance in a conventional manner, and filling the mixture into an aerosol container. .

The properties of the foaming agent are completely different depending on the aerosol container filled with the undiluted solution, and a preferable foam cannot be obtained even with a small nozzle used in a conventional spray type aerosol. In order to obtain the foam intended for the present invention, the stock solution has a stem diameter of 0.20 to 0.32 mm and a housing diameter of 0.2.
It is necessary to put in an aerosol container equipped with a spout of the valve and injection port area 2.5～30Mm ² of 20～0.32Mm, in order to obtain a more preferred foam is the stem of the stock diameter 0.25～0.32Mm, housing diameter valve and injection port area 7 to 15 mm ² of the spout equipped with aerosol containers 0.25～0.32Mm, more buttons injection port 2.0～10Mm, especially from 4.0 to 8.
It is preferable to fill a 0 mm aerosol container.

The method of using the anhydrous foam cleaning and wiping agent of the present invention is, for example, a usual wiping with toilet paper or the like after defecation or diaper replacement, and then wiping with the toilet paper or the like sprayed several times with the product of the present invention. The effect can be further enhanced by wiping the area around the anus with toilet paper or the like sprayed several times with the product of the present invention after bathing or before defecation. There is also a method in which the product of the present invention is spray-coated directly on the periphery of the anus and then wiped off with toilet paper or the like.

[0018]

Since the anhydrous foam cleaning and wiping agent of the present invention adheres to the surface of the toilet paper in the form of foam, it has a low penetration rate into the toilet paper and can be applied in large amounts to the skin during wiping. Since the bubbles disappear after wiping, the underwear and the like are not stained. In addition, it is a skin cleansing and wiping agent which reduces friction with the skin during wiping and has a high wiping and protective effect. Also, since this anhydrous foam cleaning and wiping agent is a one-phase system containing no water, it does not need to be shaken when used,
Further, it has good jetting properties even at low temperatures.

[0019]
