[0009] Formula R-O-A 1 ~ 3 COCH 3, R
Although there are many similar polyhydric alcohol derivatives represented by —O—A 1 to 3 R, few of them have the property of being both soluble and insoluble due to the temperature difference of the aqueous solution like the 7 components shown above. That is, most of the components, when mixed with water, show only the property of being either soluble or insoluble within the range of room temperature to 100 ° C. In this case, in terms of cleaning / removing "dirt", the dissolving type has no effect, while the insoluble type has an effect.

However, in terms of another effect of the present invention, that is, the regeneration of the cleaning waste liquid, the insoluble type is not suitable. Because the "dirt" remains solubilized and is not accompanied by the natural separation phenomenon of the "dirt", it must be discarded when the "dirt" concentration reaches saturation.

However, the seven components listed in the present invention are 5 to
Since it has both the solubility and the insolubility in the range of 80% by weight and the temperature of 40 to 100 ° C, the action of dissolving and removing the "dirt" from the article to be washed becomes active due to the insolubility of water in the components during heating. Become. Then, after reaching 40 ° C. or less, the “dirt” solubilized in the component disappears due to water solubilization of the component, loses solubility, spontaneously separates in an aqueous solution, and precipitates or floats.
As a result, the cleaning liquid is always restored to the state of a new liquid.

The cleaning conditions of the present invention are as follows:
The reason why the concentration is limited to 80% by weight and the operating temperature is 40 to 100 ° C. is that the concentration of 5% by weight or less reduces the dissolving power of “dirt”, and the concentration of 80% by weight or more significantly reduces the separability of “dirt”. Because. At a temperature of 40 ° C. or less, water insolubilization of the components does not occur, so that the cleaning property cannot be obtained.
