Abstract:
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; andiii) 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:A.sup.b --CH.sub.2 --Bwherein:A.sup.b 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--CH.sub.2 --B moiety in the range of from 8 to 21 carbon atoms; (2) one or more C.sub.1 -C.sub.3 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 --CH.sub.2 --B moiety, to position .omega.--2 carbon, the terminal carbon minus 2 carbons; and (4) the surfactant composition has an average total number of carbon atoms in the A.sup.b --CH.sub.2 moiety in the above formula within the range of greater than 14.5 to about 17.5; andB 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.
