The invention relates to an alkoxylate mixture having H formula (I) where PO is a propyleneoxy unit, EO is an ethyleneoxy unit, n has an average value in the range 1.6-3.3 per 2-ethylhexyl group and m has an average value in the range 3.0-5.5 per 2-ethyl-hexyl group, and containing less than 1.5% by weight of unreacted 2-ethylhexanol; the said mixture being obtained by reacting 2-ethyl-hexanol in a first step with propylene oxide and in a second step the propoxylated mixture obtained with ethylene oxide. The alkoxylate mixture is a good cleaning surfactant and wetting agent and is also readily biodegradable. |
