Use of a mixture;a) of a hydroxy-terminated polyether of the block structure (A) (EO)x1′-(PO)y1-(EO)x1″, where y1 is 40 to 70 and (x1′+x1″) is 30-60 and (x1′+x1″)/y1 is less than 1 (component A), and;b) of a hydroxy-terminated polyether of the block structure (B) (EO)x2′-(PO)y2-(EO)x2″, where y2 is 15 to 55 and (x2′+x2″) is 2-50 and (x2′+x2″)/y2 is less than 1 (component B), where (x1′+x1″)/y1 is >(x2′+x2″)/y2, for solubilizing sparingly water-soluble active ingredients, which have a solubility in water of not more than 5 g/l at 25° C. and 0.1013 MPa, in aqueous formulations. |
