Abstract

PURPOSE:To obtain a bathing agent composition giving excellent bathing effect, especially skin-smoothening effect, by compounding sodium sulfate, sodium bicarbonate, calcium carbonate and potassium chloride at specific ratios. CONSTITUTION:The objective composition contains 4.0-10.0pts.wt. of sodium sulfate, 80.0-90.0pts.wt. of sodium bicarbonate, 1.0-3.0pts.wt. of calcium carbonate and 1.0-3.0pts.wt. of potassium chloride as main components, A bathing effect equivalent to the bathing in a high-quality hot spring e.g. smoothening the skin as well as warming the body, improving blood flow and activating metabolism, can be easily attained by bathing in a bath containing the bathing agent.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a bath additive composition that has excellent bathing effects, particularly in providing smoothness to the skin.

[Conventional technology]

Bathing has a variety of effects, including the ability to relieve the fatigue of the day and relax both mind and body.

Various bath additives have been developed to further enhance the effects of bathing.

Among these, attempts have been made for some time to add various oils and alkaline ingredients to bath additive compositions for the purpose of smoothing the skin during bathing (for example, in the 1970s,
0-30687).

[Problem that the invention seeks to solve]

However, conventional bath additive compositions of this type have had problems such as staining the walls of the bathtub depending on the quality or quantity of the oil, and reduction in commercial value due to oxidation during formulation and storage.

On top of that, too much oil can make your skin sticky,
There was also the problem that the relaxing feeling of bathing was impaired.

On the other hand, when adding alkaline ingredients, if the alkalinity is weak, a large amount must be used to be effective, and if you use something with a strong alkalinity, the alkalinity will become too strong when the bath water becomes low, and the skin surface will become too alkaline. There was a problem in that there was a risk of causing injury.

(Means for Solving the Problems) As a result of intensive research to obtain a bath additive composition that does not have the above-mentioned problems and therefore has a bathing effect that particularly makes the skin smooth, the inventors have found that tutrium sulfate, It was discovered that this could be achieved by a specific combination of sodium bicarbonate, calcium carbonate, and potassium chloride, and the present invention was completed.

That is, in the present invention, J ditrium sulfate 40 to 10.0
Provides a bath additive composition containing as main components 80.0 to 90.0 parts by weight of sodium hydrogen carbonate, 1.0 to 3.0 parts by weight of calcium carbonate, and 1.0 to 3.0 parts by weight of potassium chloride. It is something to do.

The present invention will be explained in detail below.

Sodium sulfate used in the present invention is its anhydrous salt (Na2
SO4), monohydrate salt (Na2SO4.120), decahydrate salt (Na2SO4.10H20), etc. can be suitably used. Among these, decahydrate salt (Gruber's salt) can be easily obtained as so-called human silk Mfr's salt, neutral crystal Mfr's salt, by-product Mfr's salt, etc.

The blending amount of sodium Ta acid is 4.0 to 10. This is the Oii part.

Sodium hydrogen carbonate (NaHCO3: baking soda) may be a commercially available product produced by an ammonia soda method or the like.

The blending amount is 80.0 to 90.0 parts.

Calcium carbonate is a compound represented by the molecular formula CaCO3, and may be a commercially available product made from limestone.

The blending amount is 1.0 to 3.0 parts by weight.

Potassium chloride is a compound represented by the molecular formula KCρ, and may be a commercially available product separated and purified from potassium ore.

The blending amount is 1.0 to 3.0 parts by weight.

For the present invention, the above-mentioned blending amounts of the components constituting the bath agent composition are extremely important.

As is clear from Table 1, there is a clear difference in effect in terms of "smoothness of the skin" between the amount of the present invention (example) and the amount of other ingredients (comparative example). .

It should be noted that each component of the bath agent composition of the present invention has a mutually correlated relationship, and the amount of each component cannot be determined independently of the amount of other components, so it is necessary to keep various balances in mind. However, it was necessary to overcome the difficulty of determining the optimal blending amount for an integrated product.

Therefore, it was necessary to conduct numerous experiments, and the amount of the present invention was determined based on the data obtained.

The composition of the present invention may also contain the following additive components that have been conventionally used as bath additives.
