Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a novel bath additive and a method for producing the same.

(b) Conventional technology There are various types of Yunohana that are naturally produced.

On the other hand, bath additives that are widely available on the market include sodium bicarbonate, sodium sulfate, medicinal herbs or their extracts,
The ingredients listed in the section (i) Bath additives on page 353 of the Quasi-drug Manufacturing Guidelines for Fragrances, Colorants, etc. (Japan Official Publications Kyokin Line, 1984) are mainly used.

In addition, quasi-drug manufacturing guidelines (Japan Official Kyokin Line, 19B
In addition to the ingredients listed in (i) Bath additives on page 353 of 4), the ingredients listed in (i) Medicinal cosmetics on page 354 of the same book and the ingredients listed in Cosmetic Raw Materials Standards Volume 2, Annotation I
Some of the components listed in , ■ (Japan Official Publications Kyokin Line, 1984) are used.

On the other hand, Yunohana, which contains natural aluminum salts, has a low pH of around 3 to 4 when dissolved in tap water, which may cause hot water sores on people with sensitive skin and the elderly. And, keep the hot water for a long time. - Q stem? ? J/ l= 7-Jim attractive metal part (
(copper, iron, or their alloys, etc.) may rust or the bathtub may become discolored, so it must be flushed and washed within the same day.Also, polyester, stainless steel,
□If used on a bathtub made of materials such as enamel, it will lose its luster. Furthermore, since yunohana contains insoluble impurities, it had to be placed in a cloth bag and dissolved in hot water, which was a serious drawback. Moreover, aluminum ions easily form precipitates even in extremely slightly alkaline aqueous solutions, so under natural environmental conditions, many alum springs have a pH
There are no examples of acidic rice quality of 2 to 4 being stable with baking soda spring.

Therefore, aluminum ions are hardly included in the hot spring water of natural sodium bicarbonate springs.For this reason, there are no bath additives that stably coexist alkaline components and aluminum salts in water. Furthermore, when a bath additive containing an acidic component and an alkaline component is packaged as a powder, changes occur over time due to the generation of 17I acid gas and the like due to reaction.

Therefore, it has long been desired in the industry to develop a technology that does not change over time after packaging and a technology that can stably coexist alkaline components and aluminum salts in water (without allowing aluminum to precipitate). Ta.

(c) Problems to be Solved by the Invention The purpose of the present invention is, firstly, to find a method that allows inorganic aluminum salts such as alum to be dissolved in tap water, etc., but still exist stably without precipitating aluminum. There is a particular thing. The second objective is to find a method that does not generate secondary components such as carbon dioxide gas due to changes over time and allows the inorganic aluminum salt to exist stably.

(d) Means for solving the problem As a result of research, the present inventors found that at least one salt of inorganic aluminum and tyrone, sulfosalicylic acid, oxine-5-sulfonic acid, acetylacetone, CyDTA,
Oxalic acid, mannitol, citric acid, tartaric acid, malic acid, and at least one of oxycarboxylic acids or salts thereof coexist, - and 3f! Iji, I found out what was done.

This combination is a breakthrough that was not well known in the industry and indicates a new direction for bath additives in the future.

The present invention will now be described in detail.

(f) Examples (Example 1) 1 g of inorganic aluminum salt and 1 g of alkali salt shown below were added to 1 cup of distilled water, and the presence or absence of precipitation of aluminum hydroxide was examined.

Results Among potassium aluminum sulfate dodecahydrate (potash alum) and anhydrous salt (baked alum), aluminum sulfate, aluminum nitrate, sodium aluminate, potassium metaaluminate, sodium aluminum sulfate A, and hexahydrate of aluminum chloride. 1 type and sodium bicarbonate, sodium carbonate, sodium sesquicarbonate, calcium oxide, potash soap, calcium carbonate, slaked lime, sodium hydroxide,
When one type of potassium hydroxide was placed in water, aluminum hydroxide precipitated in all combinations.

(Example 2) In the aluminum salt precipitation test and skin irritation test shown in Tables 1 and 2, 20 g of sample was heated at 40°C, 2001
I put it in hot water and investigated.

For the rust generation test, (1) 1 g of the sample was placed in 1201 hot water at 40°C, (2) the copper plate was half immersed in hot water, and heated at 40°C for 2 days.
I kept it. (3) After two days had passed, the same copper plate was replaced with fresh hot water, and the operations (1) and (2) were repeated for one month to examine the presence or absence of rust.

The components of the sample tested are as shown below.

Sample No. 101 Yunohana 100% containing inorganic aluminum salt Sample No. 102 Sodium hydrogen carbonate 25% sodium acid anhydride 15% anhydrous potassium aluminum sulfate 45% anhydrous sodium sulfate 15

Equimolar amounts of the acids shown in Tables and Table 2 were added,
In addition, colorants, fragrances, enzymes, etc. were added to Samples 101 to 117 of F-.

In Tables 1 and 2, it is clear that only the combination of the present invention caused no precipitation of insoluble aluminum salts, did not cause rust, was not irritating to the skin, and was excellent in all respects. I was able to complete the bath salts.

(Example 3) When the bath additive of the present invention is packaged as a powder in a container such as an aluminum bag, ji2r! II gas generation was investigated. The test method and samples are as shown below.

After mixing the bath additive of the present invention in powder form, it was stored tightly in a glass container for 6 months, and the generation of carbon dioxide gas in the container was measured by gas chromatography to examine changes in the components over time. The results are shown in Tables 3 to 5.

02 to No. 218 Instead of citric acid and potassium aluminum sulfate (decahydrate) in Sample No. 201, organic acids and inorganic aluminum shown in Tables 3 to 5 were used in the same molar ratio.

From Tables 3 to 5, when the bath additive of the present invention is packaged as a powder in the presence of an alkali salt, the organic acids include sodium citric acid, tartaric acid, sodium tartrate, malic acid, or sodium malate. It is clear that a combination of at least one of the above and at least one of anhydrous potassium aluminum sulfate or anhydrous aluminum sulfate as the inorganic aluminum salt is particularly preferable because it does not change over time.

(g) Effect As is clear from Examples 1 to 3, the combination of the present invention made it possible for the alkali component and aluminum ions to coexist for the first time.
