Patent ID: 8785363

Claim:
A reduced alkalinity detergent composition comprising: an effective amount of an extended chain surfactant comprising, an effective amount of an extended anionic chain surfactant of the formula R-[L] x -[O—CH—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 to 20 carbon atoms, L is an intermediate polarity linking group, x is the chain length of the linking group ranging from 2-16, y is the average degree of ethoxylation ranging from 1 to 5, and M is an anionic group; an effective amount of extended nonionic chain surfactant of the formula R-[L] x -[O—CH 2 —CH 2 ] y where R is a linear or branched, saturated or unsaturated, substituted or unsubstituted aliphatic hydrocarbon radical having from about 6 to about 20 carbon atoms, x is the average degree of propoxylation ranging from 1-16, and y is the average degree of ethoxylation ranging from 1-20; and a non-ionic linker co-surfactant; wherein the required alkalinity for optimal soil removal is less than the required alkalinity for optimal soil removal when alkylphenol ethoxylate or alcohol ethoxylate compositions are used further wherein caustic is present in an amount of less than 1500 ppm; wherein the ratio of nonionic extended chain surfactant to anionic extended chain surfactant is greater than about 1:1 by weight percent.
