ABSTRACT:
A method of making a heavy duty clear, single phase, solvated built aqueous liquid detergent composition. The composition consists essentially of at least one nonionic surfactant, at least one builder, an effective amount of a water soluble polymeric anionic hydrotrope to render the composition clear, stable and single phase which hydrotrope is a specific polymer of maleic anhydride and at least one alpha olefin, and water wherein the composition has a pH in the range of from 6 to 9. The novel hydrotrope used is a hydrolyzed (a) copolymer of maleic anhydride and a C.sub.6 to C.sub.24 alpha olefin or (b) ter- or higher polymer of maleic anhydride with two or more C.sub.6 to C.sub.30+ alpha olefins as long as one of the alpha olefins is a C.sub.2 to C.sub.18 alpha olefin and the ratio of alpha olefins present are such that the average alpha olefin carbon chain length in the ter- or higher polymer is greater than about 6 and less than about 18. Additionally, methods of making stable, one phase compositions of this type which further include a cationic fabric softening agent which are clear, stable and single phase.
