Abstract
A detergent composition that includes from 1 to 40 wt. % of a secondary alkane sulfonate surfactant with an average of 15 to 18 carbon atoms in a linear alkane chain, from 1 to 40 wt. % of an anionic surfactant other than the secondary alkane sulfonate surfactant, and from 0.01 to 8% of an alkyl hydroxysultaine co-surfactant. Greater than 50 wt. % of the alkyl chain of the secondary alkane sulfonate is C15 to C18 secondary alkane sulfonate.
