A stable liquid detergent composition containing a self-structuring surfactant system. A liquid detergent composition that includes a linear alkyl benzene sulfonate, and a co-surfactant selected from a zwitterionic surfactant, an amphoteric surfactant, a branched non-ionic surfactant and mixture thereof, with a first viscosity of no less than 3000 mPa&#xb7;s measured at a first shear rate of 0.5 s, and a second viscosity of no more than 2,500 mPa&#xb7;s measured at a second shear rate of 20 s, and the ratio of the first viscosity to the second viscosity is no less than 3.

Stable liquid detergent composition containing a self-structuring surfactant system

A stable liquid detergent composition containing a self-structuring surfactant system, where without using external structurants, the liquid detergent composition exhibits good shear thinning properties while maintaining stability under high shear. A liquid detergent composition comprising a linear alkyl benzene sulfonate, a zwitterionic and/or amphoteric surfactant and optionally polyethylene glycol.

A self-structuring surfactant system. A stable liquid detergent composition containing the same. A liquid detergent composition that includes a linear alkyl benzene sulfonate and a branched nonionic surfactant that is a branched alkoxylated alkyl alcohol.

A stable liquid detergent composition containing a self-structuring surfactant system, where without using external structurants, the liquid detergent composition exhibits good shear thinning properties while maintaining stability under high shear. A liquid detergent composition that includes a linear alkyl benzene sulfonate, an amine oxide surfactant and little or no alkoxylated alkyl sulfate and unalkoxylated alkyl sulfate.
