Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composition for a transparent solid detergent suitable for frame kneading and, more particularly, to a composition containing N-acylglutamic acid as a base and suitable for frame kneading. The present invention relates to a composition for a transparent solid detergent having low adhesiveness.

[0002]

2. Description of the Related Art Transparent solid detergents are used particularly for facial cleansing because of their high transparency and high commercial value. The conventional transparent solid detergent produced by the frame kneading method is mainly composed of a fatty acid soap, and saccharides such as sugar, glycerin and sorbitol, or polyhydric alcohols are added as a clarifying agent, and the mixture is added to ethanol. It is usually manufactured by heating and dissolving in water, solidifying, drying, and forming.

[0003] However, the conventional transparent solid detergent produced in this way has insufficient transparency,
In order to solve this drawback, it has been proposed to blend a monofatty acid ester of glycerin or polyglycerin, a sugar ester, or a fatty acid ester of an alkylene glycol (Japanese Patent Application Laid-Open No. 3-188200). The disadvantages have not yet been fully solved. Further, since the conventional transparent solid detergent containing the fatty acid soap as a main component is essentially the same as an opaque fatty acid soap,
Defects such as skin irritation due to an increase in pH due to hydrolysis of the free alkali in the soap and the fatty acid soap in use, poor foaming in hard water, and generation of scum during use are inevitable.

In order to solve the drawbacks of the conventional transparent solid detergent containing a fatty acid soap as a main component, the present applicant has proposed a transparent solid detergent based on an N-long-chain acyl-optically active acidic amino acid salt. Agents have been proposed. That is, a combination with polyhydric alcohol, carbohydrate, thiourea, urea, and maltitol (JP-B-59-14515) and a basic amino acid salt are used as bases (JP-B-59-55).
No. 0), urea is added to widen the area of transparency and improve devitrification (JP-B-59-19596), and N-length is added to improve transparency and shape retention. A chain acyl-optically active acidic amino acid is used as a mixed salt of an alkali metal having a certain degree of neutralization and a basic amino acid (Japanese Patent Publication No. 61-4876), improvement of devitrification under high humidity and odor In order to improve the above, a method of adding urea and a cationized polymer (Japanese Patent Publication No. 7-62151) was proposed.

Thereafter, in order to further improve transparency, usability and storage stability, a salt of an alkali metal and ethanolamine is used as an N-long-chain acyl acidic amino acid salt, and the molar composition ratio of the alkali metal and ethanolamine is used. 2
0:80 to 35:65 (Japanese Patent Publication No. 6-7659)
No. 3), a potassium salt and a sodium salt having a degree of neutralization of N-acylglutamate of 1.5 to 2.0 are used so as to prevent coloring and crystallization and not to impair transparency. And the molar ratio of both is 9: 1 to 2: 8,
In addition, a composition in which the total blending amount of both is 30 to 70% by weight (WO94 / 16041) has been proposed.

However, a transparent solid detergent based on an N-long-chain acyl-optically active acidic amino acid salt is soft and easily soluble in water, and therefore has a strong adhesion to processing tools and the like.
For this reason, there has been a problem that processing such as cutting and molding is difficult.

In connection with this problem, the hardness is increased, the adhesion to the container is reduced, and browning due to heating during production is prevented.
In order to prevent unpleasant odor and browning during high-temperature storage, the salts of N-long-chain acyl acidic amino acids are converted into potassium salts, sodium salts and ethanolamine salts, and urea is added (Japanese Patent Application Laid-Open No. 6-264092). An attempt has been proposed. However, potassium salts and sodium salts of N-long-chain acylamino acids and ethanolamine salts hardly eliminate problems such as softness and ease of dissolution, and therefore cannot reduce the adhesion. Therefore, there has been a strong demand for solving the above problems. It is a known fact that a lower alcohol is used as a solvent for a transparent soap. It is known that a lower alcohol such as ethyl alcohol or propyl alcohol can be blended in an appropriate amount (Japanese Patent Publication No. 6-76593). The above-mentioned patent publication does not mention at all the relationship between the property and the lower alcohol, including its examples.

On the other hand, conventionally, a shaped article molded from soap is
It is known to be incorporated in transparent soap to give a desired appearance and luxury, and to enhance commercial value. A transparent soap molded article including such a molded article is formed by fixing a molded article made of colored soap or opaque soap on a support made of transparent solid soap, and putting the composite in a molding mold. It is produced by a method in which a molten liquid of a transparent solid soap is poured into a mold, cooled and solidified, and the formed molded article with a built-in molded article is taken out of the mold.

[0009] However, when the conventional transparent bar soap is used, the shaped article is not sufficiently fixed to the support.
When the transparent soap melt is poured into the mold, the position of the shaped object on the support table fluctuates, and the formed article separates from the surface of the support table and creates an air pocket therebetween, thereby significantly impairing the appearance. There is such a problem. Therefore, various devices have been devised for fixing the shaped article to the support so that the position of the shaped article on the support stand does not fluctuate or separate. For example, the colored soap molded article and the support base are connected and fixed from the back side of the support base by a needle protruding above the front side,
A method of placing the connected body in a mold, injecting a transparent soap melt into the mold, and solidifying by cooling (Japanese Patent Laid-Open No. 57-1553)
No. 00) is known. Further, a convex portion is provided at a lower portion of the soap-produced product, and a concave portion that fits into the convex portion of the molded article is formed on a support base formed of transparent solid soap, and the convex portion of the molded article is formed. A method in which both are fixed by fitting into a concave portion of a support base, the fitted body is put into a forming mold, a melt of a transparent soap is injected and solidified in the forming form, and the obtained molded article is taken out from the form (Japanese Patent Laid-Open No. 59-172599) is known.

Further, Japanese Patent Application Laid-Open No. 61-98800 discloses that a molded article and a support are integrally cast in a casting mold made of silicone rubber or the like, and the cast molding is covered with a transparent soap. A method for producing a soap containing a molded object to be cast is described, and JP-A-5-339599 discloses:
The lower part of the modeled object is formed by a soap having a large specific gravity, the upper part is formed by soap having a small specific gravity, the modeled object is put into a mold, and the specific gravity of the upper and lower parts of the modeled object is placed in the mold. Inject a transparent soap melt with an intermediate specific gravity,
A method of cooling and solidifying this to produce a soap containing a molded article is known, and thereby it is known to improve the stability of a molded article. Furthermore, with a molded article,
In order to improve the adhesiveness with the transparent soap melt to be injected, the surface of the shaped article is wetted in advance with a liquid component such as ethanol or glycerin, and the transparent soap melt is injected into this. Attempts have also been made.

[0011] However, the above method is inefficient for industrially implementing the method, and the adhesiveness (affinity) between the shaped article and the transparent soap melt is insufficient. Is injected, there is a problem that air bubbles are formed at the interface between the injection liquid and the molded article, thereby deteriorating the appearance of the product. In addition, conventional transparent bar soaps have insufficient transparency, so that the appearance quality and the see-through performance by incorporating a shaped article and seeing through it are unsatisfactory.

[0012]
