JPS62164617A - Foamable bathing agent - Google Patents

Abstract

PURPOSE:To obtain a foamable bathing agent having excellent storability and remarkably improved stabilizing effect compared with an agent containing magnesium oxide as a stabilizer, by adding a silicic acid as a stabilizer to a foamable bathing agent composition obtained by mixing a carbonate with an organic acid. CONSTITUTION:A foamable bathing agent is produced by mixing a carbonate (e.g. sodium bicarbonate, magnesium carbonate, etc.) and an organic acid (e.g. succinic acid, citric acid, etc.) and mixing the obtained foamable bathing composition with preferably 0.5-10wt% silicic acid as a stabilizer. The silicic acid is especially a light silicic anhydride produced in vapor phase and its amount is preferably 2-4wt%. Silicic anhydride has strong water-absorptivity and contains water which cannot be removed by ordinary drying conditions. It is considered that the higher stabilizing effect of the silicic anhydride as against that of the magnesium oxide is caused by the property of silicic anhydride to contain about 4 times the amount of water in weight.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a foaming bath agent which can be maintained in a stable state upon use.

[Technical background of the invention and its problems]

As a type of bath additive that has recently been used, foaming bath additives that are a mixture of carbonate and organic acid have come into use. However, this foaming bath agent is extremely unstable because it reacts with the presence of a small amount of moisture (*) and generates carbon dioxide gas. Even if this type of bath additive is stored in a sealed package, it will gasify little by little during long-term storage, causing the packaging to swell and completely ruin its appearance, lowering the product value. The disadvantage was that the foaming performance was low and a satisfactory effect could not be obtained. In order to improve the above drawbacks, a foaming bath agent containing magnesium oxide and/or sodium aluminate as a stabilizer was filed as Japanese Patent Publication No. 60-9009, but further improvements were desired.

[Purpose of the invention]

Therefore, the applicant researched whether there was a stabilizer that could keep the foaming bath agent in a stable state for a long period of time until it was used, and found that if silicic anhydride was used as a stabilizer, the foaming bath agent could be kept in an even more stable state. It has been discovered that a sex bath agent can be obtained.

[Summary of the invention]

The foaming bath agent of the present invention is prepared by mixing a foaming bath mixture containing a carbonate and an organic acid as a stabilizer in a proportion of 0.5 to 10% by weight in the total composition of silicic anhydride τ. It is.

[Embodiments of the invention]

F1 The foaming bath agent according to the present invention will be explained below.The foaming bath agent is a foaming bath composition in which a carbonate and an organic acid are completely mixed, and silicic acid is mixed therein as a stabilizer.

Examples of carbonates include IFII, such as dry sodium bicarbonate, sodium carbonate, magnesium carbonate, and calcium carbonate.
Gold, heavy carbonate, potassium bicarbonate, etc. are mixed in an amount of 5 to 80% by weight, preferably 10 to 50% by weight based on the total weight of the composition.

Also, as the acid, for example, dry co-phosphoric acid, sodium succinate, citric acid is used, and it is mixed in a proportion of 10 to 200% by weight based on the total amount of M in the composition, especially 30 to 150% by weight. Mixing is preferred.

The 80% mixture of carbonate and organic acid is adjusted depending on the effect of the bath additive.

When co-phosphoric acid is used as an organic acid, it is mixed with 20 to 150% by weight of sodium bicarbonate, and citric acid is used as the organic acid. When using 1, it is preferable to mix it in an amount of 40 to 300% by weight based on sodium hydrogen carbonate.

As the stabilizer, silicic acids such as silicon dioxide and silicic anhydride (also referred to as silicic acid) are used, and they are mixed in an amount of 0.5 to 10% by weight based on the total weight of the composition. It is preferable to mix ice-making water sulfuric acid in a proportion of 2 to 4 by weight.

If the amount of stabilizer is less than 0.5M, it will react with the moisture contained in the air inside the packaging bag and generate gas until it is used, causing the packaging bag to swell with the gas. On the other hand, if you mix the stabilizer on a 10-weight board, the bath water will become cloudy and floating substances will appear, or the soap will not foam easily. The effect also decreases.

The reason why silicic anhydride is effective as a stabilizer for carbonates and organic acids is that it has strong water absorption and contains water that cannot be removed under normal drying conditions. I think it's because I have a tendency to say things. This phenomenon is also evident from the fact that a hygroscopic substance such as ``Nirika Gel'' is added to the homologous substance as a desiccant agent.

Furthermore, the foaming bath agent of the present invention contains fragrances, pigments, vitamins, and hot spring active ingredients in addition to the above-mentioned essential ingredients.

One or more types of proteolytic enzymes are mixed in, and binders, disintegrants, lubricants, excipients, etc. are selectively added, and the product is formed into powder or solid form. Foaming bath preparations may also be packaged with waterproof packaging materials, such as metal laminate films, or
There are things that can be stored in sealed containers.

Experimental Example 1 Citric acid 53 parts Sodium hydrogen carbonate 42 parts Silicic anhydride □ Part fragrance 1 part Colorant Appropriate amounts were mixed evenly and solidified to a diameter of 3 cm and a thickness of 1 cm, and the lining agent of the present invention was applied to a metal laminate. When it was placed in a film packaging bag, sealed, and stored at room temperature for one year, there was no abnormality in the packaging bag. When this solidified bath agent was placed in bath water, it melted while foaming moderately, giving a pine surge effect to the skin.

Experimental example 2 Succinic acid 50 parts Sodium hydrogen carbonate 40 parts Silicic anhydride 2 parts Fragrance
1 part tar-based pigment Appropriate amount of this was all solidified and packaged in the same manner as Experimental Example 1, and stored at room temperature for one year, and the same results as Experimental Example 1 were obtained.

Experimental Example 3 Succinic acid 50 parts Carbonic acid 50 parts Silicic anhydride 3 parts Fragrance 1 part Color Appropriate amount: 1L Results equivalent to those obtained in Example 1 were obtained.

(Effects of foaming) In the above experimental examples, when foaming bath additives in which magisium oxide was mixed as a stabilizer instead of silicic anhydride in the composition were stored under the same conditions, all foaming bath additives of the present invention were Carbon dioxide gas was generated faster and the packaging bag expanded. The reason why the bath agent of the present invention is suitable for longer storage than the bath agent using magne/lamb oxide as a stabilizer is that the silicic anhydride used as the stabilizer is also used as a dehydrating agent and that it adsorbs the components of the layer agent. This is thought to be due to the lack of moisture and the fact that it easily absorbs moisture.
