Zusammenfassung:The liq. formulation of 1,2-benzisothiazolin-3-one comprises (wt.%): (a) 1-25 1,2-benzisothiazolin-3-one (I); (b) 3-7 NaOH; (c) 3-63 H2O; and (d) 20-65% polyglycol triol(s) of formula (II). in (II): nx, ny and nz = 2 or 3; when nx, ny and nz each = 2, then x + y + z = not more than 13.2; and when nx, ny and nz each = 3, then x + y + z = not more than 4.45. Also claimed are: (i) a liq. formulation as above, in which the polyglycol triols are selected from glycerol ethoxylate with an average mol. wt. of less than or equal to 700 and glycerol propoxylate with an average mol. wt. of less than or equal to 350; and (ii) a liq. formulation of 1,2-benzisothiazolin-3-one that is stable at low. temp., comprising (wt.%): 15-23 1,2-benzisothiazolin-3-one; 3-7 NaOH in ca. 40-65 of glycerol propoxylate with an average mol. wt. of 250-266; and 5-42 H2O.
