Description

TECHNICAL FIELD The present invention relates to a transparent solid stone and a transparent stone dough. More specifically, the invention does not require fine adjustment of the amount of water or an aging period until the weight is reduced. The present invention relates to a transparent solid stone and a transparent stone or dough that can be easily produced and have good transparency and stability over time in weight. BACKGROUND ART Transparent stones are widely used as detergents because they are aesthetically pleasing and have excellent safety and detergency. Generally, transparent stones contain a moisture-absorbing component such as a polysaccharide as an essential component in order to provide transparency, and also contain a volatile component such as ethanol. However, in the case of the transparent solid stone II, if the moisture-absorbing component absorbs moisture, the transparency is rather reduced. Therefore, it was necessary to strictly adjust the water content with a hot roll while checking the transparency and the moisture content. In addition, when a volatile component is blended, the volatile component is volatilized and the weight is reduced, so that a ripening period of several weeks to several months is required until the weight is reduced. That is, in the production of the transparent solid stones, it was very complicated to control the transparency so that it was good, and also the transparency and the stability over time of the weight were good.

Also, if the conventional transparent stone material is used to process striped stone together with other opaque stone materials, the transparency of the transparent stone portion will be increased by the moisture contained in the opaque stone. There was a disadvantage that the stripes were lost and the stripes became unclear. Also, some of the transparent solid stones actually used contain sorbitol, which is a polysaccharide, in order to increase the transparency. Turbidity, and the temporal stability of the transparency is not impaired. Therefore, there has been a demand for a transparent stone which can be easily produced without requiring fine adjustment of the amount of water and aging period, and which has excellent transparency and stability over time of weight.

On the other hand, although organic amines such as triethanolamine were already blended into the transparent solid stone, they were not blended at a high concentration. Also, it is completely known that, by blending an organic amine such as triamine with a high concentration, a transparent solid stone and a transparent stone dough that can be easily produced and have good stability can be obtained. Did not. DISCLOSURE OF THE INVENTION The present invention has been made in view of such a situation, requires less labor for fine adjustment of the water content, and can be easily produced without requiring an aging period until the weight loss subsides. Further, it is an object of the present invention to provide a transparent solid stone and a transparent stone and dough having good transparency and stability over time in weight.

In view of this situation, the present inventors have conducted intensive studies on transparent solid stones and transparent stones which are easy to produce and have good stability. As a result, the inventors have determined that they can be used for saponification. By using sodium hydroxide and organic amine at a ratio of and the amount of alkali to fatty acid at a predetermined saponification equivalent, a transparent stone can be obtained without using polysaccharides, alcohols and the like as essential components. Further, they found that this transparent stone was easy to produce and had good stability, and completed the present invention.

That is, the present invention relates to a stone mainly composed of a salt of a fatty acid, which is obtained by saponifying a fatty acid or animal or vegetable oil and an alkali,

1) The alcohol, sodium hydroxide and organic amine, wherein the molar ratio of sodium hydroxide to organic amine is 1: 0.8 to 1: 2,

2) The transparent solid stone, wherein the amount of the alkali is 2 to 3 saponification equivalents relative to a fatty acid or animal or vegetable oil.

Triethanolamine is particularly preferred as the organic amine.

Further, the present invention relates to a stone dough mainly comprising a salt of a fatty acid, which is obtained by saponifying a fatty acid or animal or vegetable oil and an alkali, 1) The alkali force is sodium hydroxide and an organic amine, wherein the molar ratio of sodium hydroxide to organic amine is 1: 0.8 to 1: 2,

2) The transparent stone dough, wherein the amount of the alkali is 2 to 3 saponification equivalents to a fatty acid or animal or vegetable oil.

The transparent stone dough of the present invention can be solidified as pellets.

The present invention also relates to a transparent solid stone obtained by molding the transparent stone. In the present invention, “transparent” means a state that is substantially transparent and has little turbidity, and means that the transmittance of visible light is approximately 25% or more. Also,

"Transparent" is not limited to colorless and transparent ones.

In the present invention, there is a distinction between “transparent solid stone 鹼” and “transparent stone 鹼 dough”. “Transparent solid stone 鹼” is a concept used for a solid formed and solidified in a use form, The state before being molded into 鹼 is referred to as “transparent stone 鹼 cloth”. Further, in the present invention, the “transparent solid stone” includes a stone which is partly transparent in a usage form.

The term "saponification equivalent" as used in the present invention refers to the minimum amount of alcohol required to convert all fatty acids or animal and vegetable oils into salts of fatty acids, that is, stones. And

The transparent solid stone and the transparent stone dough of the present invention are transparent stones that do not contain polysaccharides or alcohols such as sorbitol and ethanol as essential components. Therefore, unlike transparent stones containing polysaccharides, turbidity due to moisture absorption, crystal precipitation, and the like are not easily generated, and the transparency with time is excellent. Further, since the transparent solid stones and the transparent stones of the present invention do not require moisture-absorbing components such as polysaccharides, the labor for adjusting the water content is reduced, and the volatile components such as alcohol reach equilibrium and the weight is reduced. The production is easy because it is not essential to wait for the aging period until the temperature stops.
