(Transparent type) was prepared, and an evaluation test was performed on the evaluations (3) to (5). The results are shown in Table 6.

  First, regarding the temporal stability, good results were shown for all of Samples 1 to 13. Next, with regard to water separation inhibition, the weight ratio of component (A) to component (D) ((A) / (D)), the weight ratio of component (B) to component (D) ((B) / (D )) And the weight ratio of component (C) to component (D) ((C) / (D)) was found to show good results only when in a specific range. Specifically, from samples 10 to 13 and other samples that showed good water separation stability, (A) / (D) was 0.01 to 0.08, and (B) / (D) was 0.02. When 0.08 and (C) / (D) are in the range of 0.2 to 1.1, it was found that good water separation inhibitory properties are exhibited.

  The present invention can be widely used as a gel-like cleaning material that is excellent in stability over time and further in water separation suppression.
