from 0 to 25 percent by weight based on the product of (1), (a), (b) and (c) of a synthetic detergent selected from the group consisting of straight-chain alkyl benzene sulfonates and straight-chain alkyl sulfates,
Claim 4
Dependent Claim
35 words
neutralizing the product of (1) with at least one equivalent of base per mole of SO3 consumed in (1) and hydrolyzing the product of (1) at a temperature of between 100* and 200* C. and
Claim 5
Dependent Claim

neutralizing and hydrolyzing the product of (2); and from about 2 to 15 percent by weight of water based on the hydrogenated olefin sulfonate content.
Claim 7
Dependent Claim
39 words
hydrogenating from 50 to 100 percent of the unsaturated carbon-carbon double bonds in the product of (2), and B. from about 2 to 15 percent by weight of water based on the hydrogenated olefin sulfonate content of the bar.
Claim 8
Dependent Claim
26 words
a quantity of water in the range 2 to 15 percent by weight of the active detergent component sufficient to plasticize the active detergent component, and
