Composition for cleansing and wiping skin

A composition for cleansing and wiping skin in the circumanal region which comprises at least one oil selected from the group consisting of jojoba oil, natural squalane and glycerin tri-2-ethylhexanoate. The composition according to the invention is preferably used after excrement is wiped off with usual toilet paper and facilitates removal of excrement residues on the skin of circumanal region. Besides, when the composition is applied to the circumanal skin prior to defecation, it prevents excrement from sticking to the skin or makes excrement easy to be wiped off. The composition may be sprayed on conventional toilet paper or impregnated into nonwoven fabric, cloth, paper etc. on application. Such materials containing the composition according to the invention is effective in preventing any aggravation to hemorrhoids or the like.

BACKGROUND OF THE INVENTION 
(i) Field of the Invention 
This invention relates to a composition for cleansing and wiping skin, and 
more specifically, to a cleansing and wiping composition which facilitates 
removal of excrement remaining on the skin of circumanal region after 
defecation when excrement is wiped off with usual toilet paper or the like 
and which, when applied to circumanal skin prior to defecation, makes it 
difficult for the excrement to stick to the skin during the subsequent 
defecation or makes it easy to wipe off the excrement from the skin and 
thereby keeps the circumanal region clean and prevents any aggravation to 
hemorrhoids or the like. 
(ii) Description of the Prior Art 
For the wiping and cleansing treatment of the anus following defecation, 
toilet paper is generally used. Bidets and other washing apparatus using 
warm water, and cleansing cotton are also used, but rarely. From the 
viewpoint of skin irritation or filth removal, washing with warm water is 
the most desirable. However, washing apparatus using warm water are 
expensive and require cumbersome handling, and therefore have not come 
into wide use yet. Cleansing cotton costs much per one use, feels cold and 
is disadvantageous in that it cannot be disposed in a flush toilet. For 
these reasons, the actual situation is that toilet paper and coarse toilet 
paper are most generally used in wiping the anus after defecation. 
The skin in the circumanal region has small wrinkles and creases and hair, 
and those portions of excrement residues which have got into such minute 
parts can be wiped off only with difficulty. Furthermore, sticking 
excrement residues, after solidification, are difficult to remove. 
On the other hand, regeneration products account for about 70% of toilet 
paper and coarse toilet paper which are generally used. Physically, they 
are rather tough and therefore crumpled soft prior to use, but even they 
may injure the skin, causing excoriation. Excrement residues sticking to 
the skin parovide sources of propagation of bacteria, and decomposition 
products and the like produced by bacteria promote aggravation of the 
injured skin or cause itching, eruption or sore of the circumanal region. 
To clean the circumanal region is very important also to general public 
from the public health standpoint. In particular, to babies having a 
delicate skin and bedridden old people or to those suffering from diseases 
of the anus, such as hemorrhoids, that is important. Such people having 
some or other skin lesions in the circumanal region are sensitive to 
stimuli to the skin in the circumanal region and easily feel a pain upon 
stimulation in said region. Consequently, they tend to reduce the wiping 
force, and the results are insufficient wiping and increase in excrement 
residues. 
Some of those with hemorrhoids, for instance those with internal hemorrhoid 
or light archoptosia, must push back internal hemorrhoid or archoptosia 
protruding from the anus after defecation into the anus by their fingers. 
Such treatment is usually accompanied by pain and thus something which 
physically facilitates the pushing of internal hemorrhoid or archoptosia 
into the anus is desired. 
SUMMARY OF THE INVENTION 
Under these circumstances, the present inventors conducted intensive study 
so as to develop a composition for cleansing and wiping the circumanal 
region which might be used after defecation in a simple and easy manner, 
might remove, to a sufficient extent, excrement residues remaining after 
wiping with toilet paper, might keep the circumanal region clean and might 
give a smooth and refreshing feeling after use. As a result, they found 
that the above object can be attained by using a composition which 
comprises specified oils. 
Thus, this invention provides a composition for cleansing and wiping the 
skin which comprises at least one oil selected from the group consisting 
of jojoba oil, squalane and glycerin tri-2-ethylhexanoate.

DETAILED DESCRIPTION OF THE INVENTION AND PREFERRED EMBODIMENTS 
It is necessary that oil to be used in this invention does not feel sticky, 
has a good affinity to the circumanal skin of the special region, does not 
stimulate skin and gives smooth and refreshing feeling of use. For such 
purposes, jojoba oil, squalane and glycerin tri-2-ethylhexanoate can be 
used. Liquid paraffin, olive oil and lanolin, which have been generally 
used in preparing baby oils and cosmetic oils conventionally, can not be 
favorably used for the circumanal region because they cause sticky feeling 
to remain. 
The silicone oil to be used in accordance with the invention may be used 
either alone or in combination of two or more. 
The cleansing and wiping composition according to the invention may, as 
desired, contain a microbicide, a pharmacologically active agent (e.g. 
antiinflammatory agent), an aroma chemical, and so forth, in addition to 
the above essential components. 
For putting it to practical use, the cleansing and wiping composition 
according to the invention is filled in an appropriate container. It is 
especially convenient to use the composition in a sprayable form using 
either a propellant gas or a pressure-accumulating pump bottle. 
The cleansing and wiping composition according to the invention is used, 
for example, in the following manne. Thus, after post-defecation wiping in 
the conventional manner with toilet paper or the like or on the occasion 
of diaper exchange, finish wiping is carried out with toilet paper or 
tissue paper sprayed several times with the composition according to the 
invention. The effects of this method of use can be further improved by 
wiping the circumanal region with tissue paper or toilet paper sprayed 
several times with the composition according to the invention after 
bathing or prior to defecation. In another mode of use, the composition 
according to the invention is directly applied to the cicumanal region, 
followed by wiping off with toilet paper or tissue paper, for instance. 
Further, the composition according to the invention can be prepared or used 
in the form of an impregnated material. As a support material for 
impregnation, may for example be mentioned paper, nonwoven fabric, cloth, 
polymer film, sponge and foamed plastics, among which, paper and nonwoven 
fabric are especially preferred. 
When the composition to be impregnated has large impregnation coefficient, 
the impregnation may be carried out either firstly immersing the support 
material into above-mentioned oils, followed by removing the excess oil by 
a pressurizing means etc., or directly spraying the oils to the support 
material. On the other hand, when the composition has small impregnation 
coefficient, similar procedures can be carried out but using mentioned 
oils admixed with organic solvents such as n-hexan, followed by removal of 
the solvents. The impregnation method, however, is not limited to the 
above. 
A preferred manner of use of the cleansing and wiping composition thus 
prepared is, for example, a finish wiping after post-defacation wiping in 
the conventional manner with toilet paper etc., or on the occasion of 
diaper exchange. The effects of the cleansing and wiping material can be 
further improved by wiping the circumanal region with the cleansing 
material according to the invention after bathing or prior to defecation. 
The following examples illustrate the invention in more detail. 
EXAMPLE 1 
A cleansing and wiping composition formulated as indicated in Table 1 was 
filled in a pressure accumulating pump bottle with 30 ml capacity. Ten 
persons suffering from hemorrhoids used tissue paper sprayed with the 
composition after defecation, and the feeling of use was investigated. The 
results are shown in table 1.

EXAMPLE 3 
Degrees of skin damage caused when toilet paper produced from wastepaper 
(reference material) was used and when the same toilet paper sprayed with 
a wiping and cleansing agent consisting of equal amounts of jojoba oil, 
squalane and glycerin tri-2-ethylhexanoate (invention composition) was 
used, were evaluated according to the following method. 
METHOD OF EVALUATION 
The skin of the inner side of human forearm was wiped with the above 
reference material or the invention composition 4 times with a force of 
around 100 g/cm.sup.2, followed by collecting the replica of the skin 
condition by the sump method and observing with a light microscope. 
RESULTS 
Considerable streaks were observed on the epidermis after wiping with the 
reference material (FIG. 1), while almost no streaks were observed with 
the use of the invention composition (FIG. 2). Thus, it has been clearly 
demonstrated that the invention composition has an effect of preventing 
skin damage.
