Gemini surfactants, surfactant mixture and detergent compositions

Novel gemini surfactants of formula (I) are claimed, as are also surfactant mixtures comprising (by wt.) (A) 0.1-99% surfactants having ≥ 2 hydrophilic and ≥ 2 hydrophobic groups, with the hydrophilic and hydrophobic groups separated by a ≥ 4C linear or cyclic spacer group (i.e. a gemini surfactants...

Zusammenfassung:	Novel gemini surfactants of formula (I) are claimed, as are also surfactant mixtures comprising (by wt.) (A) 0.1-99% surfactants having ≥ 2 hydrophilic and ≥ 2 hydrophobic groups, with the hydrophilic and hydrophobic groups separated by a ≥ 4C linear or cyclic spacer group (i.e. a gemini surfactants); (B) 0-99% nonionic, non-gemini surfactant; and (C) 0-99% anionic, non-gemini surfactant. In (I), R and R = H or 1-6C alkyl; R - R = H or 4-24C alkyl; n = 2-10; m and p = 1-40; X and Y = H, -CH2COOM or -SO3M; M = H, alkali(ne earth) metal or quat. N base, with the proviso that at least one of R /R or of R /R = H. Also claimed are detergents containing 3-50 wt.% of the surfactant mixture, the preferred detergents being HGSMs (i.e. detergents dissolved in water at up to 50 degrees C and used on table- or cooking-ware).
