Abstract

PURPOSE:To obtain a skin cleaning and wiping agent, capable of applying a sufficient amount of a solution onto the skin without fouling underwear and having high wiping and protective effects by filling an oil and a propellant under a specific vapor pressure in an aerosol container equipped with a specified jetter. CONSTITUTION:An anhydrous foam cleaning and wiping agent is obtained by filling a stock solution composed of one or two or more oil selected from vegetable oils, animal oils and synthetic oils and a propellant (e.g. liquefied petroleum gas or Freon<gamma>) having 1.0-7.0kg/cm<2> (25 deg.C) vapor pressure in an aerosol container equipped with a valve having 0.20-0.32mm, especially 0.25-0.32mm stem caliber, 0.20-0.32mm, especially 0.25-0.32mm housing caliber and a spout having 2.5-30mm<2>, especially 7-15mm<2> jetting port area or further preferably an aerol container having a button jetting port with 2.0-10mm, especially 4.0-8.0mm caliber. Since the resultant medicine is a foam, the permeation rate to toilet paper is low and its large amount can be applied to the skin in wiping. After the wiping, is not fouled due to disappearance of the foam. Since the medicine is a one-phase system without containing water, is not required and excellent jetting properties are exhibited even at low temperatures.

Description

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 specifically, it is a quick disintegrating anhydrous agent which is used by being sprayed on toilet paper or the like and which does not need to be shaken during use and has excellent low temperature stability. The present invention relates to a cleansing and wiping agent for the peripheral part such as a foamy anus, urinary organ and vulva.

[0002]

2. Description of the Related Art A hot water purifier is also used in part for cleansing and wiping after defecation / urination, during menstruation, etc., but due to high equipment cost, it has not yet spread, and it is generally a toilet. Paper is used.

However, it is difficult to sufficiently clean the skin with a toilet paper, and the skin around the anus is stimulated by friction during use. Therefore, when there is a disease around the anus such as hemorrhoids, the symptoms are symptom. Worsen. Further, after urination or during menstruation, frequent repeated rubbing due to wiping stimulates the skin around the urinary organs and the vulva, thus causing various problems.

In order to solve such a problem, it has been proposed to apply a cleaning / cleaning agent to toilet paper for use (JP-A-59-225111 and JP-A-62-242611).
Japanese Patent Laid-Open No. 1-265019, Japanese Patent Laid-Open No. 2-32011, etc.).

These cleansing and cleaning agents make it easier to remove the excrement remaining after wiping off the excrement with normal toilet paper or the like after defecation / urination or during menstruation, and damage to the skin due to friction and pain during wiping Etc., and by applying it to the skin around the anus in advance before defecation, the excrement does not easily adhere to the skin during the next defecation, and the excrement is easily wiped off. By keeping the peripheral parts such as the vulva clean, it is possible to prevent deterioration of hemorrhoids, rashes, itch and other various symptoms.

By the way, the technology relating to aerosol preparations has made great progress at present, and is widely used as household products, cosmetics, pharmaceuticals, industrial products and the like. Therefore, the aerosol agent is a stable foam, quick break foam, spray type (Mist type), etc., depending on the delicate combination of the active ingredients such as propellant, solvent and drug. It can be divided into various dosage forms.

From the viewpoint of application of aerosols, stable foams are used in shaving foams, hair care products, etc., and fast-disintegrating foams are used in shaving lotions and some external medicines. Among them, the quick-disintegrating type foam does not spray into the air like the spray type, and is particularly effective for, for example, a topical bath aerosol, and even when compared with the stable type foam, the dosage is mechanically spread. Since it is not troublesome, 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, the conventional spray type and rapid disintegrating type foams have a problem that the sprayed solution penetrates into the toilet paper and is applied to the skin in a small amount. Although the stable foam is applied on the skin in a large amount, there is a problem that the foam remains after the application and the underwear is soiled.

[0009] Therefore, an object of the present invention is to provide a skin cleansing and wiping agent capable of applying a sufficient amount of a solution on the skin, and without contaminating underwear or the like, and having a high wiping protection effect. ..
