Abstract (en)
[origin: EP0090605A1] A washing composition, especially a fabric washing powder containing substantial proportions of soap. At least 10% by weight of the composition is a soap of an unsaturated fatty acid in order to take advantage of the superior solubility properties of such soaps. The composition also contains a water-soluble surface-active compound containing a nitrogen atom which is either positively charged or capable of taking a positive charge in aqueous solution. This compound counteracts the deposition of scale on heater elements. Examples of such compounds are quaternary ammonium salts and lecithin.
