(Conventional technology)
External factors, such as light, temperature, and atmospheric humidity, are significant factors for people comfortably indoors. In particular, in a room heated / cooled by an air conditioner, the use of the heating / cooling device generally significantly reduces the humidity level of room air. In air-conditioned rooms and buildings, the effect of air-conditioning is generally maintained by not opening windows, so that fresh air cannot be supplied directly into the room or building. However, similar problems often occur in heated dwellings, especially in winter. Indoors often circulate dry heated air and, in addition, often lack sufficient ventilation due to energy savings and sensitivity to cold air. In such cases, winter atmosphere, has almost dried, further, its humidity is lowered by heating the room. People to spend at such a low humidity in the room, often eye and pain, throat dry and of, or suffered the pain, such as in many cases the irritation of the skin "stress", breathing upset (this is, the respiratory organs Pain in the upper and lower parts of the body, such as bronchial pain and neck pain) and make it easier to catch a case.

Another indoor humidification method that has been put into practical use is to install electric equipment for generating steam. However, as is well known, electrical equipment often tends to be contaminated by algae, fungi, fungi, and the like. Therefore, when releasing the water vapor particles into the room in the air, there is a risk you release the microorganisms that can cause disease together. In addition, electrical equipment of this type often occupies a large space, which impairs the indoor landscape and generates unacceptable noise during operation. In addition, electrical equipment is operated with liquid water, so there is a risk of water spilling during filling of water or if the electrical equipment is accidentally turned over. In addition, power is always required.

Dimensional stability composition comprises as its main components, including the C ₈ -C ₂₆ carboxylic acid alkali metal salt of from about 1 to 40 weight percent. The fatty acids can be obtained, for example, from natural fatty substances, in particular vegetable and animal fats. Generally, the soaps exhibit antimicrobial activity, and microorganisms such as fungi, bacteria or algae, if present , do not propagate in large quantities on the surface of the compact.

According to one preferred embodiment of the invention, an alkali metal salt of a carboxylic acid from a fatty acid fraction based on coconut oil, palm kernel oil or tallow is used, because it has a high content of saturated fatty acids.

The dimensionally stable compositions of the present invention preferably contain an alkali metal carboxylate of the type described above in an amount of about 2 to 10% by weight, especially about 3 to 8% by weight. Preferred carboxylic acids are myristic acid, palmitic acid and stearic acid, which, after neutralization with sodium hydroxide or the like, can be used directly as the corresponding salt.

According to one preferred embodiment of the method of the present invention, in addition to the above-mentioned alkali metal carboxylate and water, the dimensionally stable composition comprises a solvent, a regulator, a fragrance, an insecticide, a preservative, a thickener , dyeing agents, Pigments, additives selected from moisture indicator and mixtures thereof, in an amount of 0-20 wt%.

Solvents Suitable solvents can be any water-soluble solvent, such as, for example, short-chain alcohols containing about 2 to 8 carbon atoms.
According to one preferred embodiment of the present invention, the composition is formulated substantially free of solvent. However, for example via additives such as perfume oils, Ru is Rukoto introduces a small amount of solvent Oh.

Modifier The dimensionally stable composition used in the present invention can include a modifier. As used herein, the term "regulator" refers to a compound capable of adjusting the vapor pressure of water present in a dimensionally stable composition to within a predetermined range. Suitable regulators are, for example, non-hygroscopic salts, for example NaCl or hygroscopic salts, for example CaCl ₂ or Na ₂ SO _4, and swellable materials, such as clay, silica gel, are molecular sieves or polio Lumpur . The above modifiers can be present in finely dispersed or coarsely dispersed form (eg granules) in an air humidifier.

Polio Lumpur <br/> preferred polio Lumpur, for example, an alcohol containing 2 or more hydroxyl groups and up to about 30 carbon atoms, such as ethane-1,2-diol, propane-1,2-diol , Propane-1,3-diol, butane-1,4-diol, butane-2,3-diol, pentane-1,5-diol, hexane-1,6-diol, octane-1,8-diol, diethylene glycol , Neopentyl glycol, 1,4-bishydroxymethylcyclohexane, 2-methylpropane-1,3-diol, hexane-1,2,6-triol, glycerol, diglycerol, polyglycerol, trimethylolpropane, trimethylolethane Pentaerythritol, sorbitol, methyl glycosides, dimer diols, trimer triols, glucose, alkyl polyglycosides, and disaccharides and polysaccharides. These alcohols can be present as ethylene oxide or propylene oxide adducts, with or without sulfonic acid groups, in the dimensionally stable composition. Lactams such as ε-caprolactam can also be used as regulators.

Especially for suitable perfumes, for example, can be referred to the following documents: E.Ohloff, "Riechstoffe und Geruchsinn" , (ISBN 3-540-5256-2, Springer Verlarg), 1990. Suitable fragrances are, for example, plant fragrances, petrochemical fragrances or animal fragrances. Perfumes may use orange peel oil, sandalwood oil or frankincense, depending on where the air humidifier is to be placed, for example, a bathroom or bedroom.

According to the present invention, as a pesticide or anthelmintics, perfumes according to the literature (e.g., clove oil, cinnamon oil, mustard oil), dimethyl phthalate, diethyl benzoate, phenyl cyclohexanone, ethyl hexane Earl, Chlorinated hydrocarbons (eg, DOT), phosphorus compounds, carbamates, nicotine or mineral oils can be used. A toxicologically safe insecticide or anthelmintic should be used depending on the location of the air humidifier.

Thickeners In addition, the dimensionally stable compositions can include thickeners that can contribute to the dimensional stability of the composition. Basically, suitable thickeners are organic high molecular weight substances which absorb water and swell in the process. Natural organic thickeners include agar, carrageenan, tragacanth, gum arabic, alginate, pectin, polyose, guar gum, locust bean gum, starch, dextrin, gelatin, casein and the like. As natural organically modified substances, for example, carboxymethylcellulose and homologous cellulose ethers, hydroxyethyl and hydroxypropylcellulose, gum ethers, starch derivatives and the like can also be used.

Dyes or pigments or dimensionally stable compositions can include dyes or pigments or mixtures thereof, which can provide a warning effect or a signaling function, while generally exhibiting a decorative effect. Dyes or pigments or mixtures thereof can be evenly distributed as coloring components in the dimensionally stable composition. However, colored components can be applied only to the surface of the dimensional stability composition. By doing so , the dimensionally stable composition can be used as an interior decoration or display medium.

The moisture indicator dimensional stability composition can further include a moisture indicator or a freshness indicator, which provides a visual indication of the residual moisture of the dimensional stability composition or the use of the pack prior to its intended use. Can be displayed as to whether or not it has been opened. For example, such an indicator, when combined with a suitable optical measurement system for measuring the water content of the dimensionally stable composition, allows the dimensionally stable composition to be accessible to inaccessible locations (eg, ventilation and air conditioning systems). , if you place, not good a disadvantage measurement to waste time, such as the opening of the ventilation system without'll line.

Form of Dimensionally Stable Composition According to one advantage of the present invention, the dimensionally stable composition can be in substantially any form due to its ease of manufacture, for example, blocks, spheres, Examples include a cube, a bar, a disc, and a portrait form. The rate of water evaporation can be controlled as needed via the surface of the compact. Solid soap structures are advantageous in this regard. That is, the molded body is not to be aggregated (coalescence) As the time passes. For example, for ventilation system applications, the dimensionally stable composition in liquid form can be poured into a given holder, which can be easily used in suitable equipment after solidification of the composition. After the water and other volatile components have evaporated from the dimensionally stable composition, all that remains is a mixture of the alkali metal carboxylate and the non-volatile additives, if present. Thus, such residues can then be used, for example, for hand or body cleansing. However, the residue can also be suitably processed and reused in the manufacture of the dimensionally stable composition.

All components were added to water and heated to 70 ° C. and homogenized at the same temperature . If necessary, the pH was adjusted to 7-11 by addition of a small amount of sodium hydroxide. The low viscosity liquid could be poured into the mold and solidified at a temperature below 50 ° C. Then, molded bodies were produced from the blocks.

Characteristics of the molded articles of Examples 1 to 3 The molded articles of Examples 1 and 2 have a whitish color. In contrast, in the embodiment 3, the molded body without bluish color to lilac was obtained. When the packed molded body (Example 3) was taken out of the airtight waterproof pack, after several minutes, the molded body lost its surface color (pH change due to carbon dioxide absorption). This allows the user to know that the system has not been opened and that its operation has begun.
