• Specific examples include lauryl succinate , myristyl succinate, palmityl succinate 2-dodecenylsuccinate, 2-tetradecenyl succinate.
• Succinate builders are preferably used in the form of their water-soluble salts, including sodium, potassium, ammonium and alkanolammonium salts.
• polycarboxylates are oxodisuccinates and mixtures of tartrate monosuccinic and tartrate disuccinic acid such as described in US 4,663,071.
• suitable fatty acid builders for use herein are saturated or unsaturated C10- 18 fatty acids, as well as the corresponding soaps.
• Preferred saturated species have from 12 to 16 carbon atoms in the alkyl chain.
• the preferred unsaturated fatty acid is oleic acid.
• Other preferred builder system for liquid compositions is based on dodecenyl succinic acid and citric acid.
• Detergency builder salts are normally included in amounts of from 3% to 50% by weight of the composition preferably from 5% to 30% and most usually from 5% to 25% by weight.
