Abstract
Detergent compositions with high sudsing properties comprise an anionic surfactant of the alkyl sulfate, alkyl ethoxy sulfate, 2-sulfonated fatty acid methyl esters, alkyl benzene sulfonates, secondary alkyl or alkenyl sulfates, alkyl ethoxy carboxylates, sulfated or polyhydroxy fatty acid amides class, and a specially selected soap such as sodium 2-butyl-1-octanoate. The compositions provide spontaneous emulsification of grease even at neutral pH, especially in the presence of calcium ions. Sudsing may optionally be boosted by incorporating magnesium ions into the compositions. Laundry and dishwashing compositions are provided. Compositions containing a polyhydroxy fatty acid amide, sulfated polyhydroxy fatty acid amide, or alkyl ethoxy carboxylate are especially useful.
Claims7
A liquid detergent composition comprising from about 25% to 65% by weight of a mixed nonionic/anionic soap surfactant system which comprises:
- a) a polyhydroxy fatty acid amide of the formula ##STR3## wherein R.sup.1 is H, C.sub.1 -C.sub.8 hydrocarbyl, 2-hydroxyethyl, 2-hydroxypropyl, or a mixture thereof, R.sup.2 is C.sub.5 -C.sub.32 hydrocarbyl, and Z is a polyhydroxyhydrocarbyl moiety having a linear hydrocarbyl chain with at least two hydroxyls directly connected to the chain;
- and
- b) an anionic surfactant which is a member or mixtures thereof selected from the group consisting of primary and secondary alkyl and alkenyl sulfates, .alpha.-sulfonated fatty acid methyl esters, alkyl benzene sulfonates, alkyl ethoxy sulfates, alkyl ethoxy carboxylates, and sulfated polyhydroxy fatty acid amides, at a weight ratio of (a):(b) of from about 10:1 to about 1:10;
- and
- c) as a replacement for conventional soap material, secondary C.sub.11 -C.sub.13 soap material selected from the group consisting of water-soluble salts of 2-methyl-1-undecanoic acid, 2-ethyl-1-decanoic acid, 2-propyl-1-nonanoic acid, 2-butyl-1-octanoic acid, 2-pentyl-1-heptanoic acid, 2-methyl-1-dodecanoic acid, 2-ethyl-1-undecanoic acid, 2-propyl-1-decanoic acid, 2-butyl-1-nonanoic acid, 2-pentyl-1-octanoic acid and mixtures thereof;
- wherein said detergent composition is in a liquid state.
