Claims
- 1. A concentrate of an aqueous homogeneous cleaning composition for removing oil or grease from a hard surface consisting essentially of 20-70% by weight C.sub.6 -C.sub.20 alkyl substituted cyclic lactam, 5-20% anionic surfactant and 15-55% water, the lactam to surfactant ratio being 5-0.1 to 5-3.0, wherein the C.sub.6 -C.sub.20 alkyl substituted lactam is selected from the following: ##STR3## Where m=3, 4, 5 and n=6-20 or a pyrrolidone of the formula ##STR4## wherein n=6-20, and R', R", and R'" are H, lower alkyl, alkoxyl, cycloalkyl, or aralkyl.
- 2. The concentrate of claim 1 consisting essentially of 60% N-octyl-2-pyrrolidone, 10% sodium dodecyl sulfate and 30% water.
- 3. The cleaning composition of claim 1 wherein the C.sub.6 -C.sub.20 alkyl substituted lactam is a pyrrolidone of the following formula: ##STR5## where n=6-20, R', R" and R'" are H, lower alkyl, alkoxyl cycloalkyl, or aralkyl.
- 4. The cleaning composition of claim 3 wherein the C.sub.6 -C.sub.20 alkyl substituted pyrrolidone is from the group consisting of N-octyl-2-pyrrolidone, N-dodecyl-2-pyrrolidone, N-octadecyl-2-pyrrolodione and mixtures thereof.
- 5. The cleaning composition of claim 1 wherein the anionic surfactant is from the group consisting of alkali metal salts of C.sub.8 -C.sub.22 aliphatic sulfates or sulfonates and alkali metal salts of alkyl aromatic sulfates or sulfonates.
- 6. The cleaning composition of claim 1 wherein the anionic surfactant is an alkali metal salt of a C.sub.8 -C.sub.22 aliphatic surfactant.
- 7. The cleaning composition of claim 1 wherein the anionic surfactant is sodium dodecyl sulfate.
- 8. The cleaning composition of claim 1 wherein the lactam to surfactant ratio is 5-0.1 to 5-1.0.
