1. A liquid laundry detergent composition comprising:
- (a) from 5 wt % to 20 wt % of a C10-C20 linear alkyl benzene sulphonate (LAS), wherein the LAS is selected from the group consisting of monoethanolamine LAS, 2-aminopropanol LAS, monoisopropanolamine LAS, 1-amino-3-propanol LAS, and combinations thereof;
(b) from 2 wt % to 10 wt % of a water-soluble alkali metal carbonate;
(c) from 5 wt % to 40 wt % of one or more solvents selected from the group consisting of diols and combinations thereof; and
(d) from 4 wt % to 20 wt % of glycerin,wherein said liquid laundry detergent composition is substantially free of alkylethoxy sulfates (AES).
