Abstract

Novel low-foaming wetting agents consisting of PA1 I) 30 to 90% by weight of one or more substances of the formula ##STR1## and/or II) 70 to 10% by weight of one or more substances of the formula ##STR2## and III) 0 to 30% by weight of one or more substances of the formula ##STR3## where all percentages given are based on the total weight of the wetting agent and where PA1 R.sup.1 and R.sup.2, independently of one another, denote straight-chain or branched C.sub.4 -C.sub.20 -alkyl, C.sub.4 -C.sub.20 -alkenyl, C.sub.5 -C.sub.8 -cycloalkyl, C.sub.6 -C.sub.12 -aryl which may be mono- to trisubstituted by C.sub.1 -C.sub.12 -alkyl, or denotes C.sub.7 -C.sub.10 -aralkyl, the aromatic portion of which may be mono- to trisubstituted by C.sub.1 -C.sub.4 -alkyl, PA1 R.sup.3 denotes straight-chain or branched C.sub.12 -C.sub.22 -alkyl, C.sub.12 -C.sub.22 -alkenyl or phenyl which is substituted by 1 to 3 alkyl groups having a total of 6 to 12 C atoms, PA1 EO and PO denote ethylene oxide and propylene oxide units, respectively, PA1 m and r, independently of one another, are 1 to 30, preferably 1 to 20, PA1 n, o, p and q, independently of one another, are 1 to 10 and PA1 s is 15 to 50.
