Patent ID: 8921295

Claim:
A concentrated neutral detergent composition comprising: one or more nonionic surfactants, comprising a primary or a secondary alcohol ethoxylate, an alcohol alkoxylate other than said ethoxylate, an aromatic ethoxylate, a modified ethoxylate, or a block polymer of propylene oxide and ethylene oxide, or any combination thereof, and wherein the amount of said nonionic surfactant is from about 1 to about 15 wt. % based upon the total weight of said concentrated neutral detergent composition; from about 0.5 to about 6 wt. % based upon the total weight of said concentrated neutral detergent composition of one or more hydrotropes comprising an amine oxide, or a glucoside, or both; from about 0.5 to about 9 wt. % based upon the total weight of said concentrated neutral detergent composition of one or more chelants; a buffer comprising one or more alcohol amines, or one or more organic acids, or any combination thereof, wherein the amount of said one or more buffers is from about 0.5 to about 8 wt. % based upon the total weight of said concentrated neutral detergent composition; from about 0.1 to about 15 wt. % based upon the total weight of said concentrated neutral detergent composition of one or more corrosion inhibitors comprising an amine, amidazole, diazole, triazole, carboxylic acid, or any combination thereof; water; and said neutral detergent composition having a neutral pH of from about 5.5 to about 8.5; and said neutral detergent composition having physical stability and being capable of cleaning soft metals and preventing scale formation thereon.
