Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a bath additive, and more particularly to a bath additive that does not leave the bath water cold and leaves the skin feeling good after bathing.

<Prior art> Bath additives are generally a mixture of inorganic salts such as mirabilite, borax, sulfur, and carbonates, combined with fragrances, colorants, plant extracts, and organic acids. By applying moderate stimulation to the surface, it activates blood circulation, relieves fatigue, and improves metabolism. Recently, when bath additives are added, they dissolve while generating carbon dioxide gas, and in order to quickly disperse oily ingredients that are insoluble or poorly soluble in water, it is necessary to add dispersants and emulsifiers, or to add oily ingredients. Therefore, in order to reduce excessive stickiness, organic and inorganic fine powders had to be mixed and added, and it was necessary to consider the specific gravity, particle size, dispersibility, etc.

Furthermore, there has been a desire for a bathing agent that not only provides the bathing effects described above but also provides a good feel to the skin after bathing.

<Problems to be Solved by the Invention> Therefore, the purpose of the present invention is to solve the above-mentioned problems of the prior art and to obtain a bath additive that not only has the efficacy of the bath additive but also has an excellent feel on the skin after bathing. do.

<Means for Solving the Problems> As a result of extensive research in order to solve the above problems, the present inventor coagulated natural rubber latex, extracted and separated it from the remaining serum after collecting the rubber component. The present invention was completed based on the discovery that an excellent bath additive could be obtained by adding ebrachytol to conventional inorganic salts.

That is, the present invention provides a bath additive containing L-quebrachytol and at least one selected from the group consisting of metal carbonate, metal bicarbonate, metal sulfate, and metal borate. I will provide a.

Further, the present invention provides a supernatant liquid obtained by coagulating natural rubber latex, and at least one kind selected from the group consisting of metal carbonate, metal bicarbonate, metal sulfate, and ammonium salt. To provide a bath salt characterized by the following.

The present invention will be explained in detail below.

Eprachytol, which is one of the components of the present invention, is contained in natural rubber latex in an amount of about 1.0 to 1.5%, and in the serum remaining after coagulating the latex, it is contained in an amount of about 15%.

In addition to L-quebrachytol, this serum contains inositol, glycoproteins, polysaccharides, etc., but other than L-quebrachytol and inositol (hereinafter referred to as L-quebrachytol) ) can be easily separated by the method described in the patent application "Method for collecting ebrachytol from natural rubber serum" filed on July 6, 1988.

Furthermore, L-quebrachytol can be used not only from natural rubber latex but also from other sources such as plants.

The bath additive of the present invention not only uses L-quebrachytol but also contains sodium bicarbonate, sodium carbonate, sodium sulfate, potassium sulfate, aluminum sulfate, ammonium sulfate, etc., to provide an even better feel to the skin. Become. These inorganic salts are naturally dissolved in natural hot springs, and these salts remove dirt from the surface of the skin, provide moderate stimulation to the skin, promote blood circulation, and have the effect of relieving fatigue. Are known. Furthermore, the inositol derivative of the present invention is produced in living organisms, and it is said that inositol derivatives play the role of information transmitting substances, and do not have functional groups that are particularly irritating to the human body. I'm never there.

In addition, L-Quebrachytol has excellent affinity for skin that has been cleaned with inorganic salts, and has moderate moisturizing properties after taking a bath, giving a moist feeling and replenishing small missing areas of the skin. It also plays a role in recovery. Since L-quebrachytol does not have any toxicity, there is no problem even if it is used in large quantities, but even if it is used in large quantities, it will only be wasted, and it is sufficient to use it in the minimum necessary amount.

The above is an example in which L-quebrachytol was purified and used. However, the natural rubber serum remaining during coagulation of natural rubber latex contains water-soluble proteins such as L-quebrachytol and ammonium sulfate. , water-soluble polysaccharides, minerals, amines, and low molecular weight hydrocarbon compounds. Therefore, only L-quebrachytol is used for 111 minutes instead of natural rubber latex! Bath salts can be made without refining.

However, the components contained in the natural rubber serum may become colored and adhere to the skin over time.

Therefore, it is necessary to remove the color and odor and collect only L-quebrachitol, ammonium sulfate, and water-soluble components.

In other words, when natural rubber latex is stabilized by adding ammonia water and then coagulated by adding dilute sulfuric acid,
Natural rubber serum is obtained.

When this is directly passed through a column filled with activated carbon, the partially amine-scented liquid becomes a colorless, transparent, and odorless aqueous solution.

At this time, if the obtained aqueous solution is acidic, p
Neutralize with alkali until H is 6.3 to 7.2.

By spray drying or evaporating this product to dryness, a mixture of L-quebrachytol and other water-soluble saccharides containing ammonium sulfate is obtained. Although there are water-soluble proteins, they are mostly decomposed into amino acids, or because they have small molecular weights and high polarity, they are adsorbed and removed by activated carbon, so they have no effect on this process.

Metal salts such as aluminum sulfate and sodium sulfate are appropriately added to 40 parts of the obtained mixture, and if necessary, colorants and fragrances are added and pulverized to form tablets, which are used as bath additives of the present invention.

Further, as the metal, metals of groups ①, H, and III are preferable, and more common and preferable ones include sodium, potassium, and magnesium.

<Example> The present invention will be specifically described below based on Examples.

(Example 1) The bath additive of the present invention was mixed uniformly with the ingredients and composition shown in Table 1 and then compressed into tablets to obtain 1550 g of tablets.

Using this bath additive, a panel of 25 people used it in the usual way for 10 days, and evaluated the overall evaluation as a bath additive (8-point feeling of use), the moist feeling of the skin, the refreshing feeling of the skin, and the state of thirst. We investigated their preferences and the results are shown in Table 2.

(Comparative Example 1) As a comparative example of the present invention, a bath additive not containing L-quebrachytol was prepared in the same manner as in Example 1 with the ingredient composition shown in Table 1, and evaluated, and the results are shown in Table 2.

Table 2 Table 1 (Unit: parts by weight) (Example 2) The bath additive of the present invention was uniformly mixed with the ingredients and composition shown in Table 3, made into granules by an appropriate method, and placed in hot water. It was made into a form that is easily dissolved.

35g of the bath additive having the above composition was placed in a bathtub for 1 to 1.5 people, and evaluated using a panel similar to Example 1. At this time, the overall feeling of use, the moist and refreshing feeling of the skin after bathing, and the thirst state were also praised by the overwhelming majority of panelists, and even those who do not normally like bath salts had negative feedback. There was no answer.

Furthermore, panelists reported that the product of this example also appeared to have a disinfecting effect and was able to quickly treat small wounds.

(Example 3) Aqueous ammonia was added to natural rubber latex to stabilize it, dilute sulfuric acid was added to coagulate the rubber content, and the content of the supernatant liquid obtained was measured, and the total solid content was 4. It was .4%. Furthermore, ammonium sulfate accounted for 1.8% of the 4.4%, and the remaining 2.6% was sugar, soluble protein, minerals, etc. This supernatant liquid, called serum, was passed through a column filled with activated carbon to remove colored substances and odors. The solid content at this time was 4.2%.
Add aluminum sulfate to this to make it 1.8%,
It was made into a homogeneous aqueous solution. The pH of this liquid was 6.0. Furthermore, 2% each of potassium sulfate and sodium sulfate were added to this aqueous solution to reduce the total solids content to 10%.
I made it so that

This product was directly spray-dried to obtain a powder.

As a result of analysis, the amount of ebrachytol contained in this powder was approximately 6%. A coloring agent and a fragrance were added to this powder and mixed, and the mixture was made into tablets or the powder was placed in an aluminum foil container to be used as a bath additive.

Evaluation of this bath additive was conducted in the same manner as in Example 1, and evaluations were obtained from 25 panelists, who gave similar answers. The results are shown in Table 4.

Table 4 <Effects of the Invention> It can be seen that the bath additive of the present invention is an excellent bath additive that moisturizes the skin after bathing and provides a refreshing feel, and is preferred by those who prefer hot water.
