Definitions

  • Liquid combinations of wash-active substances are used for most part in substantially concentrated form, for the manufacture of solutions for treating many different kinds of solid materials, and also for making liquid washing, cleaning and rinsing substances.
  • These solutions can be used as household cleaners such as laundry detergents for heavy and fine clothing, washing compounds and general utility cleaners for polished or varnished surfaces, and for cleaning wall tiles, wall coverings and the like.
  • These liquid concentrates are also employed commercially for cleaning or treatment of surfaces or solid materials such as in laundries, and other industrial applications or the like.
  • these liquid concentrates may also contain other conventional additives.
  • the wash-active concentrates it is advantageous for the wash-active concentrates to have the lowest possible viscosity, because the viscosity is often increased by the use of accompanying substances, and because it is important to avoid excessive viscosities in the interest of easy handling, such as the rapid measurement and dilution of the concentrates with water.
  • salts of sulfofatty acids with 10 to 14 carbon atoms are capable of reducing the viscosity of aqueous pastes or solutions of surface-active alkylbenzenesulfonates which optionally contain surfaceactive salts of esters of sulfofatty acids having 8 to 24, preferably 10 to 20, and especially 12 to 18 carbon atoms, and monovalent or divalent alcohols.
  • the salts of 10-to-l4 carbon-atom sulfofatty acids may be individual salts of l0-to-l4-carbon-atom chain length or mixture of such salts.

  • the viscosity reducing effect of disalts in combination with these sulfonates is completely unexpected in view of the diffiiculty encountered in dissolving disalts.
  • the viscosity lowering effect of the dissalts of sulfofatty acids with 10 to 14 carbon atoms is so pronounced that it occurs even in the presence of disalts of higher sulfofatty acids, although the C to C percentage in the said disalt mixture is to amount to at least 25 Wt. percent.
