Abstract

The present invention relates generally to surfactant and detergent compositions and, more specifically, to surfactant and detergent compositions containing an ethoxylated glycerine.

Claims

1. A composition comprising from about 30% to about 70% by weight of anionic surfactant, including from about 30% to about 60%, by weight of the composition, of 2-alkyl branched primary alkyl sulfates, from about 0.5% to about 25% by weight of a solvent comprising an ethoxylated glycerine of formula (I)

2. A composition according to claim 1 wherein said ethoxylated glycerine has a distribution wherein less than about 10%, preferably less than about 1%, by weight of the ethoxylated glycerine are ethoxylated glycerine molecules of formula (I) having a+b+c≤

2.

3. A composition according to claim 1 wherein said solvent further comprises glycerine, propoxylated glycerine, ethanol, propylene glycol, diethylene glycol, dipropylene glycol, or mixtures thereof.

4. A composition according to claim 1 wherein said anionic surfactant is selected from the group consisting of linear or branched alkyl benzene sulfonates, linear or branched alkoxylated alkyl sulfates, linear or branched alkyl sulfates, and mixtures thereof.

5. A composition according to claim 1 wherein said composition comprises from about 30% to about 70% by weight of linear or branched alkoxylated alkyl sulfates.

6. A composition according to claim 1 wherein said composition comprises from about 30% to about 60% by weight of linear or branched alkyl sulfates, linear or branched alkyl benzene sulfonates, or mixtures thereof.
