Abstract

The present invention provides a liquid laundry composition having from about 6% to about 50% of a surfactant component by weight of the laundry composition. The laundry composition includes a surfactant component having from about 0.5% to about 30%, by weight of the laundry composition, of a HLAS surfactant selected from the group consisting of alkylbenzene sulfonic acids, alkali metal salts or amine salts of C10-16 alkylbenzene sulfonic acids, where the HLAS surfactant includes greater than 50% C12.

Description

technical field [0001] The present invention relates to improved detergents and cleaning products containing certain types of alkylarylsulfonate surfactants. More specifically, the chemical composition of these alkylarylsulfonates is different from the highly branched non-biodegradable or "hard" alkylbenzenesulfonates that are still commercially available in certain countries; and their chain length The distribution is also different from the so-called linear alkyl benzene sulfonates that have been substituted in most regions. In addition, selected surfactants are formulated into new detergent compositions by combining with specific detergent builders. The compositions can be used to clean a wide variety of substrates. Background technique [0002] Historically, highly branched alkylbenzene sulfonate surfactants, such as those based on tetrapropylene (referred to as "ABS") have been used in detergents. However, its biodegradability was found to be extremely poor. Over a ...
