Detergent compositions containing selected mid-chain branched surfactants

A non-aqueous liquid detergent composition comprising:

• a) from about 35% to about 99% by weight of composition of a liquid phase, said liquid phase comprises:
• i) from about 30% to about 65% by weight of the liquid phase of an alkyl benzene sulfonate surfactant;
• ii) from about 35% to about 70% by weight of the liquid phase of a nonaqueous liquid diluent, said nonaqueous liquid diluent comprises:
• A) from about 1% to about 60% by weight of the liquid phase of a fatty alcohol alkoxylate;
• B) from about 1% to about 70% by weight of the liquid phase of a non-aqueous, low-polarity organic solvent;
• wherein the weight ratio of said alcohol alkoxylate to organic solvent is from about 50:1 to about 1:50;
• and
• iii) from about 0.1% to about 50% by weight of composition of a mid-chain branched surfactant selected from the group consisting of surfactants having the formula:
• Ab—CH2—B
• wherein:
• Ab is a hydrophobic C9 to C22, total carbons in the moiety, mid-chain branched alkyl moiety having:
• (1) a longest linear carbon chain attached to the—CH2—B moiety in the range of from 8 to 21 carbon atoms;
• (2) one or more C1-C3 alkyl moieties branching from this longest linear carbon chain;
• (3) at least one of the branching alkyl moieties is attached directly to a carbon of the longest linear carbon chain at a position within the range of position 2 carbon, counting from carbon #1 which is attached to the —CH2—B moiety, to position ω—2 carbon, the terminal carbon minus 2 carbons;
• and (4) the surfactant composition has an average total number of carbon atoms in the Ab—CH2 moiety in the above formula within the range of greater than 14.5 to about 17.5;
• and
• B is a hydrophilic moiety selected from sulfates, polyoxyalkylene, preferably polyoxyethylene and polyoxypropylene, and alkoxylated sulfates;
• b) from about 1% to about 65% by weight of composition of a solid phase of particulate material, said solid phase comprises from about 0.1% to about 50% by weight of a bleaching agent wherein said solid phase ranges in size from about 0.1 to about 1500 microns.
