Abstract

<P>PROBLEM TO BE SOLVED: To obtain a gel-form bathing agent that is used by application to the body, thus can be acted on the whole body or specific part(s) of the body directly at the formulated concentrations of medicinal components as it is, and remaining bath water is not soiled. <P>SOLUTION: This bathing agent comprises a gel layer that is hardly soluble in hot water and hydrophilic. The bathing agent is applied to the body before the body is immersed in hot water or is warmed with steamed hot towels or the like.

Description

Detailed Description of the Invention

  The present invention relates to a gel-like bathing agent applied to the body that adheres to the skin as a gel-like film and acts on the body with almost no dissolution / diffusion in bath water.

  Conventional bathing agents have various aspects such as powder, liquid, solid, etc., but their properties were intended to be used by dissolving or diffusing in hot water in the bath. However, the remaining hot water is contaminated by dissolution or diffusion of the bath agent.

  In addition, stimulants (salt, pepper extract, pepper extract, sembly extract, menthol, eucalyptus extract, salicylic acid, etc.) to obtain thermal sweating action effective for stiff shoulders, low back pain, migraine, tendonitis, rheumatism, diet, etc. When blended to a concentration that can be expected to have an effect, these will dissolve and diffuse throughout the bath water, which may irritate the genital mucosa, weak areas of the skin, areas with scars and skin troubles, and may cause irritation or inflammation. there were.

Problems to be solved by the invention

  Therefore, the present invention solves the problems of the conventional bathing agents as described above, and the medicinal ingredients blended in the bathing agent are not diluted with bath water, but act on the body at a concentration almost blended, Even if you add a stimulant (salt, pepper extract, ginger extract, assembly extract, menthol, eucalyptus extract, salicylic acid, etc.) to obtain a hot sweating effect, even if you combine it to a concentration where you can expect high effects, it will irritate and irritate the skin The object of the present invention is to provide a bathing agent form that has no danger of causing the contamination and that the remaining hot water does not become dirty.

Means for solving the problem

  The inventor has fundamentally reviewed the concept that bathing agents are dissolved or diffused in bath water, and used a thickener as a gel-like material. It has been found that the above-mentioned problems can be solved by soaking or warming with a steam towel etc. and then washing out of the bathtub.

  In the present invention, the gel bath agent using a thickener means a preparation belonging to a gel-like material having a viscosity such as cream or mayonnaise, and can be easily applied to the body. Means that it can be easily washed away by showering, hand-wiping or the like without being completely dissolved in the bath water for a sufficiently warmed time (about 2 to 10 minutes).

  Since this gel-like material has a property of being sparingly soluble in bath water and hydrophilic, only the applied portion becomes a gel-like hydrophilic film containing a medicinal component. When immersed in bath water or warmed with a steamed towel, the portion covered with this film has the same effect as being immersed in bath water having the same component composition as that contained in this film, and then If you wash it out of the bathtub or wipe it off, the bath will not get dirty.

  In the present invention, the thickener in the gel bathing agent using a thickener thickens water or a water-soluble component (medicinal component, other various components and an aqueous solution containing an emulsifier). Specifically, polymer gelling agents (hydroxyethylcellulose, hydroxypropylmethylcellulose, cetylmethylcellulose, etc.), gums (xanthan gum, guar gum, laval gum, etc.), seaweeds (sodium alginate, etc.), gelling agents (sodium polyacrylate)・ Carbomer etc.). In the present invention, polymer gelling agents (hydroxyethylcellulose, hydroxypropylmethylcellulose, cetylmethylcellulose, etc.) are preferable.

  Furthermore, if a gum (xanthan gum, guar gum, labour gum, etc.) is added to the polymer gelling agent as described above, it is possible to adjust the viscosity of the gel-like product and impart further poor solubility. These thickeners are widely used in cosmetics, quasi-drugs, and pharmaceuticals, but they are formulated as a gel-like bathing agent, and the method of use is also applied to the entire body part or the entire body. It has not been known yet to be blended into a bath composition for the purpose of soaking in bath water or warming with a steam towel.

  The content of the thickening agent (the polymer gelling agent or the total amount of the polymer gelling agent and gums) blended in the gelled bathing agent used in the present invention as described above is 0.1 to 5% by weight or 1 to 3.5% by weight is preferable. If the blending amount is less than this, it will be easy to dissolve in the bath water, and if the blending amount is large, it will become tedious and difficult to apply to the body.

  In the bath agent composition of the present invention, in addition to the essential components of the thickener and various medicinal components including a stimulant for obtaining a thermal sweating action, various components that are usually used in a bath agent composition, for example, Inorganic salts, fragrances, colorants, organic acids, surfactants, powders, antioxidants, oil components, antibacterial agents, and the like can be blended.

  The gel bathing agent used in the present invention is the above-mentioned thickener added to water, the above-mentioned medicinal components and other various components (both oil-soluble components are pre-emulsified), and by a known method, For example, it can be easily produced by stirring with a homomixer or the like. Specifically, the above thickener is added to water, stirred with a homomixer or the like to form a gel, the water-soluble medicinal ingredients and other various ingredients are added as they are, and the oil-soluble medicinal ingredients and other various ingredients. Ingredients are added after emulsification to form a preparation, and the above-mentioned medicinal ingredients and other various ingredients (oil-soluble ingredients are pre-emulsified in advance) are added to water to make water-soluble ingredients. In addition, there are various known methods such as adding a mixture into a gel by stirring with a homomixer or the like.
