<P>PROBLEM TO BE SOLVED: To provide an antifreeze keeping a good low temperature viscosity regardless of high safety and low environmental load. <P>SOLUTION: This antifreeze contains at least a compound selected from the group consisting of at least one kind of glycol (1) represented by formula 1, at least a compound (2) represented by formula 2, and at least an compound (3) (except any compound belonging to categories (1) and (2)) which is water soluble and has a viscosity at 25°C of not higher than 1 mPa s, but it never occurs that the component (1) is not less than 60 wt% and the component (3) is not more than 10 wt% based on the total weight of the components (1)-(3), and it contains also water (4). <P>COPYRIGHT: (C)2004,JPO&NCIPI |
