Abstract
New carbamide-formaldehyde condensation products which possess at least one hydrophilic and at least one hydrophobic radical, characterised in that at least one hydrophobic radical is bonded via a ##EQU1## bridge, wherein A denotes hydrogen or alkyl with 1 to 4 carbon atoms, and at least one hydrophilic radical is bonded via a N-methylol-ether bridge, to a cyclic or acyclic urea radical, these products are particularly useful as reactive surface-active agents.
Claims6
An urea-formaldehyde condensation product having the formula ##EQU23## wherein R represents alkyl, alkenyl, with 6 to 22 carbon atoms in the alkyl or alkenyl moiety,
- A represents hydrogen or alkyl with 1 to 4 carbon atoms,
- Y represents hydrogen, -- CH.sub.2 O -- Q, wherein Q is hydrogen or alkyl with 1 to 4 carbon atoms, or -- CH.sub.2 -- X', and
- X and X', independently of the other, represent a monoalkylene or polyalkylene glycol radical, bonded via an oxygen atom, and having an average molecular weight of at most 2,000 and 2 to 4 carbon atoms per alkylene unit.
