<p>Surfactants of the general formula (I): Y.A1.OC.(HR)C.C(HR1).CO.A.(C¿m?H2mO)n.R?2¿ or (II): Y.A1.OC.(HR)C.C(HR1).CO.A.(C¿m?H2mO)n.CpH2p.A.CO.(HR?1¿)C.C(HR)CO.A1.Y; where R, R?1, R2, A, A1¿, n, m, Y and p have defined meanings are effective in single phase aqueous surfactant compositions with high electrolyte loading, especially of or including alkali, particularly for hard surface cleaning applications. These surfactants do not need hydrotropes to give stable single phase compositions even with high electrolyte loadings and are resistant to hydrolytic degradation e.g. by strong alkali in such compositions.</p> |
