The present invention relates to the use of lignin derivatives, having a specific combination of degree of sulfonation and degree of oxidation, as an additive in a laundry detergent composition. Further, the present invention relates to a laundry detergent composition comprising the lignin derivative and to a laundry cleaning method.

Treatment compositions that include a surfactant system and an oligoamine, the surfactant system including linear alkyl benzene sulfonate. Related methods of use and preparation of such compositions.

The invention concerns a detergent composition, comprising: (a) from 0.5 to 40 wt. % of alignin derived anionic surfactant, wherein the lignin derived anionic surfactant has the following structure (1) or (2), preferably (1): Formula (1) or, Formula (2) wherein: M is a counterion; R.sup.1 and R.sup.2 are alkyl or alkenyl groups, each either linear or branched; the alkyl or alkyenyl groups R.sup.1 and R.sup.2 added together contain from 5 to 15 carbon atoms; with the proviso that R.sup.1 and R.sup.2 each contain at least 1 carbon atom; the invention also concerns a method, preferably a domestic method of treating a textile.
