<p>A liquid based on water solutions of corrosion inhibitors and/or diols and triols which can be substituted by one or several alkyls with number of carbons 1 to 4 contains, as a pH-value stabilizer, alkaline salts of 1,3,2-dioxaborolan-2-ol and its derivatives and/or 1,3,2-dioxaborinan-2-ol and its derivatives in the amount of 0.01 to 10.0 per cent of mass related to the total mass of the liquid. The salts whose anion is in borolane or in the borinane ring substituted by at least one hydroxyl group are of particular advantage in respect to their smooth biodegradability.</p> |
