摘要

Mixtures comprise (A) a Gemini surfactant with a polyoxyethylene structure; (B) polyethyleneglycol; and optionally also (C) a further nonionic surfactant. Mixtures comprise: (A) a Gemini surfactant with a polyoxyethylene structure and of formula (I); (B) polyethyleneglycol; and (C) optionally also a further nonionic surfactant. (I) R<1>-CHOH-CH2-(OCH2CH2)x-O-CH2-CHOH-R R and R<1> = 4-22C alkyl or alkenyl; and x = 5-400 Also included are Independent claims for: (1) production of the mixtures by peeling, pelletizing, extrusion, spray crystallization, dripping and/or drying and granulating in the thin film of a flash-dryer; and (2) rinsing or cleaning compositions comprising (wt.%): (i) the (A) + (B) + (C) mixture (0.1-15); (ii) builder (5-90); (iii) cleansing enzyme (0.1-6%); and (iv) optionally bleach (0.1-40%), together with conventional additives.
