Abstract
Improved cleaning compositions are described that are efficient in removing both food and industrial grease, heel marks, and the like from hard surfaces, wherein improved cleaning compositions contain certain nonionic surfactants and quaternary amine salts, when combined with a slightly water-soluble polar organic compound that have a surprising synergistic effect resulting in a marked improvement in the removal of hydrocarbon-containing soils as shown by decreased soaking times required for soil removal.
Claims13
A composition for removing hydrocarbon-containing soils comprising:
- a) a nonionic surfactant selected from the group consisting of a branched or linear primary alcohol ethoxylate, a secondary alcohol ethoxylate, a branched decyl/tridecyl alcohol ethoxylate, a branched or linear alkylphenol ethoxylate, a branched or linear alkyl amine ethoxylate, an alkyl ether amine ethoxylate, a branched or linear alcohol alkoxylate, alkyl glycosides, and a mixture thereof;
- b) a quaternary amine salt surfactant within the general formula (I)
- 3
- wherein R1 and R2 are the same or different and are selected from the group consisting of alkyl and substituted alkyl groups, R3 is selected from the group consisting of straight chain alkyls, branched chain alkyls, straight chain heteroalkyls, and branched chain heteroalkyls having from about 10 to 20 carbon atoms, R4 is selected from the group consisting of alkyl groups having from 1 to about 5 carbon atoms (preferably methyl), and X is a halogen atom, preferably atomic chlorine;
- c) a slightly water soluble polar organic compound;
- and
- d) water.
