Abstract

PURPOSE:To obtain a bathing agent composition having excellent body-warming effect and rust-proofing effect and usable without damaging the bath boiler and bathtub by using a chloride as a main component and adding compounds selected from sodium carbonate, disodium succinate, etc. CONSTITUTION:The objective composition is produced by using a chloride (e.g. NaCl, KCl, MgCl2 or CaCl2) as a main component and adding two or more compounds selected from Na2CO3, disodium succinate, aluminum sulfate and NaHCO3. The amount of the compounds to be added to the chloride is 0.4-8.0 pts.wt. (especially 0.5-4.0 pts.wt.) based on 1 pt.wt. of the chloride. The rusting of the bath boiler and bathtub caused by the chlorine ion generated by the use of the chloride can be suppressed by the addition of the above compounds.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a bath agent composition that has an excellent rust-preventing effect and does not damage bathtubs and bathtubs, despite containing chloride that enhances the heat retention effect. It is related to.

[Prior Art and Problem 1 The history of bath compositions in Japan is said to have its origins in hot springs and medicinal plants. Among these, bath agent compositions derived from hot springs meet the desire to easily enjoy the so-called famous hot springs at home, and their main ingredients are usually inorganic salts contained in hot spring ingredients. . However, among inorganic salts, chlorides such as sodium chloride, potassium chloride, magnesium chloride, and calcium chloride dissolve and generate chlorine ions, which have an adverse effect on the materials of bathtubs and bathtubs, such as rusting. It was difficult to use it as a drug composition.

[Means for Solving the Problems 1] The present inventors have developed a method that uses chloride as an active ingredient, which has excellent heat retention effects but is said to cause rust if added to bath agent compositions. As a result of extensive research in order to provide a bath agent composition that does not cause rust on bath pots, bathtubs, etc., we have formulated a bath agent composition that contains two or more compounds selected from sodium carbonate, disodium succinate, aluminum sulfate, and sodium hydrogen carbonate. As a result, they found a way to achieve the object and completed the present invention.

That is, the present invention provides a bath agent composition containing chloride as a main component, which contains at least two compounds selected from sodium carbonate, disodium succinate, aluminum sulfate, and sodium hydrogen carbonate. It is a drug composition.

Hereinafter, the above bath agent composition will be referred to as the bath agent composition of the present invention.

Specific examples of chlorides in the bath agent composition of the present invention include sodium chloride, potassium chloride, magnesium chloride,
Examples include calcium chloride. Furthermore, it is well known that a heat retention effect can be expected by adding these chlorides, and at the same time rusting due to chlorine ions is inevitable.

The present invention has great significance in that it contains at least two compounds selected from sodium carbonate, disodium succinate, aluminum sulfate, and sodium hydrogen carbonate in a bath agent composition containing chloride as a main component. .

The specific amount of compounding is 0.4 to 8.0 parts by weight of two or more compounds selected from sodium carbonate, disodium succinate, aluminum sulfate, and sodium hydrogen carbonate per 1 part by weight of chloride. It is preferable to blend
In particular, 0.5 to 4.0 parts by weight is more preferable. If the amount of two or more compounds selected from sodium carbonate, disodium succinate, aluminum sulfate, and sodium bicarbonate is less than 0.4 parts by weight, the rust prevention effect will not be sufficiently exhibited, and the If the amount exceeds 8.0 parts by weight, the effect of the chloride will not be sufficiently exhibited, which is not preferable, as it will damage the material.

The bath agent composition of the present invention may contain the following additive components that have been commonly used as additives for bath agent compositions.
