Abstract
Highly concentrated (60-95% active matter) foaming detergent compositions in liquid or gel form contain dialkyl sulphosuccinate, alkyl ether sulphate and/or ethoxylated nonionic detergent, optionally a fatty acid diethanolamide, optionally urea, and a solvent system of water plus optional lower alcohol, the molar proportion of ammonium ions being such that they constitute at least 50 mole % of the total cations, and being such that the dialkyl sulphosuccinate is at least partially in ammonium salt form.
Claims22
A homogeneous foaming detergent composition in liquid or gel form, consisting essentially of
- (a) from 64.5% to 95% by weight of an active detergent system comprising
- [i] a water-soluble salt of a C.sub.3 -C.sub.12 dialkyl ester of sulphosucciinic acid in which the alkyl groups may be the same or different,
- [ii] a C.sub.10 -C.sub.18 alkyl ether sulphate and/or an ethoxylated nonionic detergent, the ratio of [i] to [ii] being from 20:1 to 1:4, and
- [iii] optionally a C.sub.10 -C.sub.18 alkyl di(C.sub.2 -C.sub.3) alkanolamide, in an amount not exceeding 15% by weight of the whole composition,
- (b) from 0 to 12% by weight of urea,
- (c) from 2 to 40% by weight of a solvent system consisting essentially of water optionally together with a C.sub.2 -C.sub.3 mono- or polyhydric alcohol,
- the molar proportion of ammonium ions to total cations being sufficient to neutralise at least 8 mole % of the dialkyl sulphosuccinate (i) as well as 100 mole % of any anionic detergent-active material other than dialkyl sulphosuccinate present, and constituting at least 40 mole % of the total cations in the presence of component (iii) and at least 50 mole % of the total cations in the absence of component (iii).
