PROBLEM TO BE SOLVED: To obtain the subject composition not causing the corrosion or crack generation of plastics and not generating stains at a proper time after a rinsing treatment by compounding a specific nonionic surfactant with a specified polysiloxane copolymer. SOLUTION: This rinsing auxiliary agent composition comprises (A) 0.1-10 wt.% of a polysiloxane copolymer of formula I [R is a group of formula II or formula III (Z is H, a 1-6C alkyl; (x), (y) are each 0, 1, or larger; the weight ratio of EO:PO is 100:0 to 0:100)], and (B) 2-90 wt.% of a nonionic block copolymer of an alkylene oxide selected from ethylene oxide, propylene oxide and their mixture. The composition preferably further contains 1-20 wt.% of a hydrotropic agent such as an amine oxide. |
