Description

SOLID TRANSPARENT SOAP AND TRANSPARENT SOAP MATERIAL DESCRIPTION OF THE INVENTION The present invention relates generally to a transparent solid soap and a transparent soap material and, more particularly, to a transparent solid soap and a transparent solid material which can be easily produced. without requiring a fine control of the water content and stopping the period of maturation in reduction in weight and, in addition, exhibit high stability of transparency and weight over time. A transparent soap is visually beautiful and excellent in terms of safety and detergency, and is therefore widely used as a detergent. Generally, the clear soap is mixed with a moisture absorbing component as an indispensable component such as a polysaccharide, and the like in order to create the transparency and is further mixed with a volatile component such as ethanol, and the like. The solid transparent soap, however, declines in terms of transparency on the contrary when the moisture component absorbs the moisture content, and it is therefore required that precise fine control of the water content is done by a laminator hot while monitoring transparency and water content. In addition, when mixed with the volatile component, the volatile component volatilizes, resulting in a decrease in weight. Therefore, a maturation period as long as several weeks to several months is necessary until the decrease in weight is established. That is, it is very problematic to execute the control to exhibit high transparency and high transparency and weight stabilities over time in terms of the manufacture of the transparent soap. On the other hand, if it is processed as a soap with a strip pattern by use of a conventional transparent soap material together with other opaque soap materials, the transparency of the transparent soap portion is damaged by the moisture content contained therein. opaque soap, which leads to a disadvantage in which the bar pattern becomes blurred. Additionally, some of the transparent solid soaps currently used are mixed with the sorbitol defined as polysaccharide in order to increase the transparency. Sorbitol is, however, deposited as crystal over time to make the soap transparently hazy, and it often happens that the stability of the transparency over time becomes damaged. Under such circumstances, there has been a demand for a transparent soap that can be easily produced without requiring fine control of the water content and maturation period, and, in addition, exhibits high stabilities of transparency and weight over time. . On the other hand, it has already been practiced to mix the transparent solid soap with organic amine such as triethanolamine, but high concentration mixing is not carried out. Furthermore, it is not absolutely known that transparent solid soap and transparent soap material, which can be easily produced and exhibit high stability, are obtained by mixing with organic amine such as triethanolamine at high concentration. It is an object of the present invention, which solves such circumstances, to provide a transparent solid soap and a transparent soap material with a diminished work for fine control of a moisture content, which can be easily produced without requiring a period of time. maturation until the reduction settles down and which are good in terms of transparency and weight stabilities over time. Under such circumstances, as a result of having unconditionally made studies to obtain transparent solid soap and transparent soap material which are easy to produce and exhibit good stability, in the present invention soap is obtained which remains transparent even when it is not required polysaccharide and alcohol to be indispensable components, which involves using sodium hydroxide and organic amine in a predetermined ratio as to the alkali used for saponification and bringing an amount of alkali with respect to the fatty acid to be a predetermined saponification equivalent, and it is found that this clear soap is easy of producing and exhibiting good stability, the present invention thus being complete. To say, the present invention relates to a transparent solid soap obtained by saponifying fatty acid or animal / vegetable oil with alkali, which comprises mainly of a fatty acid salt, wherein 1) the alkali is sodium hydroxide and organic amine, and a molar ratio of sodium hydroxide to organic amine is from 1: 0.8 to 1: 2, and 2) an amount of the alkali is 2 to 3 equivalents of saponification for the fatty acid or animal / vegetable oil. It is particularly preferred that the organic amine is triethanolamine. In addition, the present invention relates to a transparent soap material obtained by saponifying fatty acid or animal / vegetable oil with alkali, which mainly comprises a fatty acid salt, wherein 1) the alkali is sodium hydroxide and organic amine, and a molar ratio of sodium hydroxide to organic amine is from 1: 0.8 to 1: 2, and 2) an amount of the alkali is 2 to 3 equivalents of saponification to the fatty acid or animal / vegetable oil. The transparent soap material according to the present invention can be solidified as a granule. In addition, the present invention relates to a transparent solid soap obtained by molding the above transparent soap material. Note that the term "transparent" implies an epithet of being substantially clear with slight turbidity as well as implying that a transmissivity of visible light is approximately 25% or more. On the other hand, the term "Transparent" is not limited to achromatic transparency, For the distinction between "transparent solid soap" and "transparent soap material", "transparent solid soap" is conceptualized as being molded and solidified in a usable form, while the "transparent soap material" is conceptualized as a state before being molded into the transparent solid soap. Further, according to the present invention, the "transparent solid soap" includes a soap molded into a usable form, a portion of which is transparent. The term "saponification equivalent" means a minimum amount of alkali necessary to transform all of the fatty acid or animal / vegetable oil into a salt of the fatty acid, ie, a soap, and an amount thereof must be taken into account as 1 saponifcation equivalent.

The solid transparent soap and the transparent soap material according to the present invention are the transparent soap in which the polysaccharide such as sorbitol or alcohol such as ethanol are not used as indispensable components. Accordingly, it is rare to generate turbidity caused by moisture absorption or deposition of crystals, and the like, which occurs in a soap comprising the polysaccharide, and excellent in terms of stability of transparency over time. On the other hand, the transparent solid soap and the transparent soap material according to the present invention are easy to produce for the reason that the work of controlling the moisture content is reduced because the moisture absorbing components such as polysaccharide are not necessary. and that a maturation period is not indispensable until the reduction in weight subsides after a volatile component such as alcohol has reached equilibrium.
