  • Patent number: 5739365
    Abstract: A method is disclosed for preparing ammonium hydroxyalkyl sulfonate by a process of reacting ammonium bisulfite and alkylene oxide wherein the pH is maintained at a relatively low value throughout most of the time of reaction of ammonium bisulfite and alkylene oxide in order to minimize the quantity of impurities, e.g. alkylene glycol and alkanolamine, in the ammonium hydroxyalkyl sulfonate. Ammonium alkanoyl alkyl sulfonates prepared by reacting such ammonium hydroxyalkyl sulfonates with fatty acids form aqueous solutions which are clear at ambient temperatures, and thus are useful as surfactants in clear liquid products.

  • Patent number: 5354829
    Abstract: A polymeric reaction product is disclosed that is a silylated polyamine-containing polymer having moieties from fatty acid moieties and/or chain extenders as difunctional organo moieties and free amine moieties and hydrolyzed and/or hydrolyzable organofunctional silane moieties and that is at least water dispersible. The reactants that produce this product are a polyamine-containing polymer with fatty acid moieties and free amine moieties and at least one amine-reactable organo functional alkoxysilane or its hydrolysis products. The former reactant results from the reaction of a polyamine-containing polymer with free amine moieties with fatty acids alone or in mixtures with other fatty acids and/or dimer acids. The polymeric reaction product is combined with a predominant amount of water to form a fiber treating formulation that can reside on the surface of one or more treated fibers.

    Abstract: Described are detergent compositions that exhibit reduced skin irritation properties while providing excellent cleaning and detergent characteristics. The detergent composition contains anionic and/or nonionic surface active materials that are at least mildly irritating to the skin and an amount of alkyl poly(ethyleneoxy)sulfonate sufficient to reduce the primary skin irritation potential of the detergent composition. The aliphatic poly(ethyleneoxy)sulfonate typically has a hydrophobe containing from 12 to about 22 carbon atoms and an average of from about 10 to about 30 ethyleneoxy groups, and is present in the detergent composition in amounts of from about 5 to about 50 percent of the total amount of surface active material in the detergent composition.
