Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a skin cleansing/detergent composition, more specifically, '
Used by spraying or coating on toilet paper, etc., it makes it easier to remove excrement remaining around the anus after wiping the excrement with regular toilet paper after defecating, and also prevents skin damage caused by friction. Or, by reducing the itchiness when wiping, suppressing the re-deposition of excrement, and keeping the area around the anus clean, it can prevent hemorrhoids, rashes, itching, etc.
The present invention relates to a composition for cleaning and wiping the skin around the anus, which prevents the deterioration of various symptoms around the anus.

[Conventional technology]

In some cases, warm water cleaners are used to clean and clean the anus after defecation, but due to the high cost of equipment, they have not yet become widespread, and toilet paper is generally used.

However, the skin around the anus has fine folds, wrinkles, and hairs that make it difficult for feces to get into these microscopic areas and wipe clean with toilet paper. Furthermore, the remaining feces that adheres to the body dries and solidifies, making it difficult to remove.

On the other hand, 70% of the commonly used toilet paper and tissue paper is made from recycled waste paper, which is physically hard and is often rubbed to make it softer when used, but it is still used to protect the skin. This will cause minor abrasions.

In addition, feces that remain on the skin become a breeding ground for bacteria, and the decomposition products produced by the feces can aggravate the deterioration of damaged skin and cause itching, rashes, and sores around the anus.

In this way, it is difficult to thoroughly clean the anus using toilet paper, and the friction caused by the use of toilet paper irritates the skin around the anus, so if you have a disease around the anus such as hemorrhoids, This may cause symptoms to worsen.

In order to solve this problem, it has been proposed to apply a cleaning agent to toilet paper before using it. This is a cleaning agent for the anal area containing a specific oil component as a main ingredient (Japanese Patent Application Laid-Open No. 59-225111
No.), a cleaning agent containing water-soluble silicone and alcohol mixed in water (JP-A No. 62-242611), water-soluble silicone and phosphoric acid pH! pH 5-9 containing lIr agent
aqueous solution aerosol type cleaning agent (Unexamined Japanese Patent Publication No. 1-265019
No.) etc.

[Problem to be solved by the invention]

However, these cleaning agents were insufficient in preventing the re-adhesion of infant feces and diarrheal stool to the skin around the anus.

As a result, redeposited feces may cause itching, rash, and sores around the anus.

Therefore, there has been a desire for a skin cleansing/wiping agent composition that is highly effective in preventing the re-adhesion of infant and diarrheal stools to the skin around the anus.

[Means to solve the problem]

As a result of intensive research to solve these problems, the present inventors found that a specific high molecular weight silicone oil and two
The present invention was completed based on the discovery that a composition containing a silicone oil with a viscosity of 30 cs or less at 5° C. exhibits a high re-deposition prevention effect.

That is, the present invention provides one or more high molecular weight silicones represented by the following general formula (1) (n represents a number from 5.000 to 20.000) and 25°C
The present invention provides a skin cleansing/wiping agent composition containing a silicone oil having a viscosity of 30 cs or less.

In the high molecular weight silicone represented by the general formula (I) used in the present invention, n in the formula is 5.000 to 20,000, particularly preferably 5.500 to 9.000.

In addition, as silicone oil with a viscosity of 30 cs or less,
Examples include dimethylpolysiloxane, methylphenylsiloxane, cyclic siloxane, amino-modified silicone, etc., which have a lower molecular weight than high molecular weight silicone (I), among others,
Straight or cyclic dimethyl silicone is preferred.

High molecular weight silicone (I) has a viscosity of 30c at 25°C.
The content is preferably 0.1 to 5.0% by weight (hereinafter simply expressed as "%") with respect to the silicone oil of s or less, and particularly preferably 0.2 to 1.0%. If this ratio is less than 0.1%, sufficient effect cannot be obtained;
Exceeding this is not preferable because the feel is not good.

In addition to the above-mentioned essential components, the skin cleansing/wiping agent composition of the present invention may contain oil-depleting components such as vegetable oil, animal oil, and synthetic oil, if necessary.

Specifically, as the vegetable oil, for example, olive oil, almond oil, jojoba oil, peanut oil, castor oil, coconut oil, palm oil, safflower oil, sunflower oil, cottonseed oil, hydrogenated coconut oil, hydrogenated palm oil, etc. are used. As the animal oil, lanolin, turtle oil, beeswax, squalene, squalane, blistane, etc. are used. Further, as the synthetic oil, liquid paraffin and glycerin tri-2-ethylhexanoate are particularly preferable from the viewpoint of protective effect and feeling of use.

Furthermore, water, an emulsifier, a bactericide, an anti-inflammatory agent, a perfume, a pigment, etc. can be added to the skin cleansing/wiping agent composition of the present invention, if necessary.

The skin cleansing/wiping agent composition of the present invention is used by filling it into a suitable container, and it is particularly convenient to use it as an aerosol preparation filled into an aerosol container.

The method of using the skin 1 cleansing and wiping agent composition of the present invention is as follows:
For example, after wiping normally with toilet paper after defecating, or when changing diapers, there is a method of finishing the wiping with toilet paper or tissue paper sprayed with the product of the present invention several times, which further prevents the re-adhesion of feces. The effect can be further enhanced by wiping the anal area with tissue paper or toilet paper sprayed with the product of the present invention several times after bathing or before defecating. In addition, the product of the present invention can be applied directly to the anal area,
There is also a method of wiping it off with toilet paper or tissue paper.

EXAMPLES Next, the present invention will be specifically explained with reference to Examples, but the present invention is not limited to these Examples.

Examples 1 to 3 Stools from healthy infants (12 months old) were collected, and after freeze-drying,
The powder was pulverized with a milk drumstick and made into a 97% aqueous solution, which was used as infant diarrhea stool.

The abdomen of a Japanese white rabbit was pricked, and Example 1.2.3 in Table 1 was prepared.
and Comparative Example 1.2.3 were thoroughly wiped with tissue paper, and the infant's diarrhea stool was thoroughly wiped with 1.0 ml of tissue paper.
g (dry weight: 30 cm) was weighed out, rolled out uniformly, and pasted on the rabbit's abdomen. After 2.5 hours, it was peeled off, and the feces adhering to the abdomen were completely extracted with distilled water, freeze-dried, and the amount of adhering feces was quantified using the urea nitrogen measurement method. The residual rate (1%) was measured. The results are shown in Table 1.

As shown in Table 1 below, Examples 1 to 3 exhibited excellent re-deposition prevention effects.
