Patent ID: 8454709

Claim:
A surfactant system or cleaning composition comprising: an extended chain anionic surfactant of formula: R-[L] x -[O—CH 2 —CH 2 ] y -M where R is a linear or branched, saturated or unsaturated, substituted or unsubstituted, aliphatic or aromatic hydrocarbon radical having from about 6-20 carbon atoms, L is a linking group, M is an iconic species selected from the group consisting of carboxylates, sulfonates, sulfates, phosphates, and combinations thereof, x is the chain length of the linking group ranging from 2-16, and y is the average degree of ethoxylation ranging from 1-5, a linker surfactant; and a multiply charged cation component selected from the group consisting of: Ca2+, Mg2+, a chelating agent, source of alkalinity or combinations thereof wherein the cleaning composition is capable of removing oily soils; wherein the ratio of extended chain anionic surfactant to linker surfactant is from 1:0.1 67 to 1:2.3 and the ratio of extended chain anionic surfactant to multiply charged cation is from 1:0.01 to 1:5.31; and wherein said cleaning composition contains no high HLB surfactants.
