Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a skin cleansing and wiping agent, more specifically, it is used by spraying or applying it to toilet paper or the like, and is excreted with normal toilet paper or the like after defecation. After wiping off the matter, it makes it easier to remove excrement remaining around the anus, and also reduces the damage to the skin due to friction or the pain at the time of wiping, keeping the area around the anus clean and hemorrhoids, rashes, The present invention relates to an agent for cleaning and cleaning the skin around the anus, which prevents itching and other exacerbation of various symptoms around the anus.

[Conventional technology]

For cleaning and cleaning the anus after defecation, a hot water washer is also used in part, but it has not yet spread because of high equipment cost, and toilet paper is generally used.

However, the skin around the anus has fine folds, wrinkles, and hair, and feces can get into these minute areas,
Toilet paper makes it difficult to wipe clean. Furthermore, the residual feces that have adhered are dried, solidified, and difficult to remove.

On the other hand, about 70% of commonly used toilet paper and dust paper is recycled paper, which is physically hard and is often rubbed to make it soft when used, but still This will cause minute abrasions on the skin. In addition, the feces remaining on the skin become a breeding source of bacteria, and due to the generated decomposition products,
Damaged skin may be aggravated and it may cause itching, rashes and sores around the anus.

In this way, it is difficult to sufficiently clean the anus with toilet paper, and the friction during use stimulates the skin around the anus, so if there is a disease around the anus, such as hemorrhoids, symptoms may occur. Cause deterioration of.

In order to solve such a problem, it has been proposed to apply a cleaning agent to the toilet paper before using it. This includes a cleaning agent around the anus mainly composed of a specific oil component (JP-A-59-225111), a cleaning agent containing water-soluble silicone and alcohol in water (JP-A-62-242611), An aqueous solution aerosol type wiping agent having a pH of 5 to 9 containing a water-soluble silicone and a phosphoric acid-based pH buffering agent (JP-A 1-265019) and the like can be mentioned.

[Problems to be Solved by the Invention]

However, when cleaning dry stools, the cleaning agent using oil components does not have a sufficient cleaning effect, and the water-based cleaning agent does not have sufficient protection effect on the area around the anus and itching around the item. The effect of alleviating was insufficient.

Therefore, there has been a demand for a skin cleansing / detergent composition which has a high cleaning effect against dry stool, a high protection effect on the anus peripheral area, and a high effect of reducing itchiness in the peripheral anus area.

[Means for Solving the Problems]

As a result of earnest studies to solve such problems, the present inventors have found that one or more oils selected from the group consisting of vegetable oils, animal oils and synthetic oils, silicone oils, and skin pH. It has been found that, by combining a buffer solution having an adjusting ability, a composition having a high cleaning effect against dry stool, a high effect of protecting the peripheral area of the item, and a high effect of reducing itching in the peripheral area of the anus can be obtained, and the present invention Has been completed.

That is, the present invention relates to the following components (A), (B) and (C) (A) one or more oils selected from the group consisting of vegetable oils, animal oils and synthetic oils (B) silicone oil (C) The present invention provides a coated cleaning / cleaning composition containing a buffer solution capable of adjusting the pH of skin to 3 to 6.

The oil as the component (A) used in the skin cleansing and cleaning composition of the present invention is, for example, vegetable oil such as olive oil, almond oil, jojoba oil, peanut oil, castor oil, coconut oil, palm oil, safflower oil, sunflower. Oil, cottonseed oil, hydrogenated coconut oil,
Examples of hardened palm oil include animal oils such as lanolin, turtle oil, beeswax, squalene, squalane,
Examples include Pristane. Examples of synthetic oils include liquid paraffin, fatty acid triglycerides such as glycerin tri-2-ethylhexanoate, and higher alcohols. Among these oils, jojoba oil, squalane, or glycerin tri-2-ethylhexanoate are particularly preferable from the viewpoint of protective effect and feeling of use. These vegetable oils, animal oils and synthetic oils are preferably contained in the composition of the present invention in the range of 5 to 50% by weight. If it is less than 5% by weight, the protective effect is poor, and if it exceeds 50% by weight, stickiness occurs and neither is preferable.

Examples of the component (B) silicone oil include methyl polysiloxane, methylphenyl polysiloxane, dimethyl polysiloxane polyethylene glycol copolymer,
Examples thereof include dimethylpolysiloxane polypropylene glycol copolymer, cyclic dimethylsiloxane, dimethyltrimethylpolysiloxane, and aminosilicon. Above all,
A linear or cyclic dimethyl silicone having a viscosity of 30 centistokes or less is preferable. These silicone oils are preferably contained in the composition of the present invention in the range of 5 to 50% by weight. If it is less than 5% by weight, not only the protective effect is poor but also the smoothness is not sufficient, and if it exceeds 50% by weight, the stability of the composition is deteriorated, which is not preferable.

Examples of the buffer solution that can adjust the skin pH of the component (C) to 3 to 6 include, for example, citric acid-sodium citrate buffer solution, lactic acid-sodium lactate buffer solution, succinic acid-sodium succinate buffer solution, phosphoric acid- Sodium hydroxide buffer, tartaric acid-sodium hydroxide buffer and the like can be mentioned. Among these, it is preferable to use a lactic acid-sodium lactate buffer solution which has a moisturizing effect. The content of the buffer solution is preferably in the range of 10 to 90% by weight in the composition. If it is less than 10% by weight, the skin pH adjusting ability is insufficient.

The skin cleansing and cleaning composition of the present invention further includes glycerin fatty acid ester, propylene glycol fatty acid ester, sorbitan fatty acid ester, sucrose fatty acid ester, alkyl glyceryl ether, polyoxyethylene alkyl ether, polyoxyethylene alkylphenyl ether, poly A nonionic surfactant such as oxyethylene polyoxypropylene ether or polyoxyethylene hydrogenated castor oil is preferably used as an emulsion.

In addition to the above-mentioned essential components, the skin cleansing and wiping agent composition of the present invention optionally has a bactericidal agent, a medicinal agent such as an anti-inflammatory agent,
Fragrances and the like can be added.

The skin cleansing and wiping agent composition of the present invention is used by filling it in a suitable container, and it is particularly convenient to use it as an aerosol preparation filled in an aerosol container or as a spray using a pressure-accumulation pump bottle.

As a method of using the skin cleansing and wiping agent composition of the present invention,
For example, there is a method of wiping off with toilet paper or tissue paper sprayed with the product of the present invention several times after wiping with toilet paper or the like after defecation, or when changing diapers. Alternatively, the effect can be further enhanced by wiping the area around the anus with tissue paper or toilet paper sprayed with the product of the present invention several times before defecation. There is also a method in which the product of the present invention is directly applied to the peripheral area of the anus and then wiped off with toilet paper, tissue paper or the like.
