Abstract (en)

[origin: WO9919431A1] The invention provides an alkoxylated aliphatic amine with 8-18 carbon atoms and 1-8 moles ethoxylation wherein the mole ratio of saturated to unsaturated aliphatic residues falls in the range 40:60 to 80:20. The invention also provides a cleaning composition which comprises: (a) 0.01-15 wt.% an alkoxylated aliphatic amine with 8-18 carbon ataoms and 1-8 moles ethoxylation wherein the mole ratio of saturated to unsaturated aliphatic residues falls in the range 40:60 to 80:20, and (b) 0.01-15 wt.% of an anionic surfactant. Cleaning compositions which comprise the amine show improved viscosity stability on storage. In the presence of the anionic surfactant at low pH the deposition of limescale on surfaces which have been treated with the composition is retarded.
