1. A detergent composition comprising:
A. a surfactant component present in an amount of about 40 to about 70 weight percent actives based on a total weight of said detergent composition and consisting of;
(1) a sodium C10-18 alcohol ethoxylate sulfate having about 2 to about 3 ethoxylate groups present in an amount of from about 9.5 to about 35 weight percent actives based on a total weight of said detergent composition;
(2) a C10-C18 alcohol ethoxylate that is capped with approximately 7 moles of ethylene oxide present in an amount of from about 5 to about 20 weight percent actives based on a total weight of said detergent composition; and
(3) an alkali metal salt of a C10-C16 alkyl benzene sulfonic acid present in an amount of from about 0 and up to about 15 weight percent actives based on a total weight of said detergent composition;
B. water present in a total amount of from about 10 to about 80 weight percent based on a total weight of said detergent composition; and
C. a C12-C14 dimethylamine oxide and present in an amount of about 5 weight percent actives based on a total weight of said detergent composition,
wherein said detergent composition is free of additional surfactants.
 
18. A unit dose detergent pack comprising:
a pouch made of a water-soluble film; and
a detergent composition encapsulated within said pouch, wherein said detergent composition comprises:
A. a surfactant component present in an amount of about 40 to about 70 weight percent actives based on a total weight of said detergent composition and consisting of;

(2) a C10-C18 alcohol ethoxylate that is capped with approximately 7 moles of ethylene oxide present in an amount of from about 5 to about 20 weight percent actives based on a total weight of said detergent composition; and
(3) an alkali metal salt of a C10-C16 alkyl benzene sulfonic acid present in an amount of from about 0 and up to about 15 weight percent actives based on a total weight of said detergent composition;
B. water present in a total amount of from about 10 to about 80 weight percent based on a total weight of said detergent composition; and
C. a C12-C14 dimethylamine oxide and present in an amount of about 5 weight percent actives based on a total weight of said detergent composition,
wherein said detergent composition is free of additional surfactants.
