Surfactant composition

A surfactant composition comprising:

• A. a first surfactant having the following structure (I):
• wherein R1 is a saturated or unsaturated hydrocarbon group having from about 17 to about 29 carbon atoms,
• wherein each of R2 and R3 is independently a straight chain or branched, alkyl or hydroxyalkyl, group having from 1 to about 6 carbon atoms,
• wherein R4 is chosen from H, a hydroxyl group, an alkyl group, and a hydroxyalkyl group, each group having from 1 to about 4 carbon atoms;
• wherein k is from about 2 to about 20, m is from about 1 to about 20, and n is from about zero up to about 20;
• and
• B. a second surfactant having the following structure (II):
• wherein R5 is an alkyl amine alkylene group, alkyl amido alkylene group, alkyl ether alkylene group, or alkyl ester alkylene group;
• wherein each of R6 and R7 is independently an alkyl group, a hydroxy alkyl group, a polyalkoxy group having a degree of polymerization of from about 2 to about 30, a hydroxyl alkyl sulfonate group, an alkyl sulfonate group, or an alkylarylsulfonate group;
• wherein R8 is a saturated or unsaturated alkyl group, aryl aralkyl group, or alkaryl group;
• or
• wherein any two of R6, R7 and R8, together with the nitrogen atom to which each is attached form a heterocyclic ring;
• and
• wherein X is chosen from halides, oxo ions of phosphorus, sulfur, or chloride, and organic anions.
