(57) Summary i) from about 0.01% to about 99.99% by weight of the composition is a surfactant mixture, wherein the surfactant mixture is of the formula (a) wherein L is M is a cation or a mixture of cations, q is its valency, and a and b are that the surfactant mixture is an acyclic aliphatic hydrocarbyl of 6 to 18 carbon atoms in total. is a number which is chosen to be neutral; R 'is selected from H and C 1 -C 3 alkyl; R''is selected from H and C 1 -C 3 alkyl; R''' is is selected from H and C 1 -C 3 alkyl; R 'and R''are all non-terminal binds to L, at least one of R' and R '' is an C 1 -C 3 alkyl; a Is an aryl] alkyl aryl sulfonate surfactant comprising at least two isomers of The alkylsulfonate surfactant system comprises two or more isomers with respect to the R ', R ", and A-L attachment positions, and comprises at least 60% of the alkylsulfonate surfactant system. In the arylsulfonate surfactant system, A is attached to L at one of the two terminal carbon atoms at a position selected from the α-position and the β-position; Having. That is, when the quaternary carbon atoms are present, the alkylaryl sulfonate surfactant system has a weight ratio of non-quaternary carbon atoms to quaternary carbon atoms in L of at least 10: 1, and Ii) 0.0001% to 99.99% by weight of the composition is a conventional hand-washing dishwashing aid; and iii) 0% by weight of the composition as measured by a hardness resistance test. A dishwashing composition for hand washing, comprising from 0.01% to 7% by weight of divalent ions selected from the group consisting of magnesium, calcium, and mixtures thereof. Embedded image |
