A liquid laundry detergent composition of desired viscosity produced by a process comprising dissolving in an aqueous medium a water-soluble builder and a surfactant blend comprising two nonionic surfactants and two anionic surfactants, such as surfactant blend being prepared by partially sulfating and subsequently neutralizing a mixture of two ethoxylated long chain alcohol nonionic surfactants containing different average numbers of ethoxy groups per molecule while employing certain values of the weight ratio of the two nonionic surfactants and the percent conversion of the nonionic surfactants to sulfated anionic surfactants.
