  • Patent number: 8629085
    Abstract: The present invention relates to a composition comprising a) an anionic compound having wetting and dispersing properties selected from the group of a1) an alkyl naphthalene sulfonate, a2) a naphthalene sulfonate-formaldehyde condensate that may optionally be alkyl substituted and mixtures thereof, and b) a nitrogen-containing surfactant selected from the group consisting of alkylamine alkoxylates, alkylamidoamine alkoxylates, alkanolamides and their alkoxylates, alkylamidopropylamines, betaines, amino acids, or any mixtures thereof, wherein the molar amount of anionic sulfonate and, if any are present, carboxylate groups in the composition is in excess of the molar amount of nitrogen-containing groups. These compositions exhibit synergistic wetting properties as compared to the surface-active components taken alone. Further, the compositions also exhibit an increased rainfastness.

  • Patent number: 7160397
    Abstract: 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.
