Abstract

Abstract Shaped washing agents based on synthetic detergents having a composition consisting essentially of (A) from 50% to 85% by weight of a tenside mixture consisting essentially of (1) from 70% to 100% by weight of the tenside mixture of a sulfonate mixture consisting essentially of (a) from 10% to 80% by weight of the sulfonate mixture of a water-soluble salt of a monoester of a sulfodicarboxylic acid selected from the group consisting of sulfoalkanedioic acids having 3 to 8 carbon atoms and sulfobenzenedicarboxylic acids, monoesterified with aliphatic alcohols having 8 to 18 carbon atoms and (b) from 20% to 90% by weight of the sulfonate mixture of a water-soluble salt of an olefin sulfonate having 10 to 18 carbon atoms, and (2) from 0 to 30% by weight of the tenside mixture of other tensides selected from the group consisting of anionic surface-active compounds, non-ionic surface-active compounds and amphoteric surface-active compounds, (B) from 12% to 47% by weight of non-tenside waterinsoluble builders customarily utilized in shaped washing agents, and (C) from 3% to 15% by weight of water.
