It was found that. linear alkylbenzenesulfonate detergent composition surprisingly respond more strongly to an alkylethylsulfate hydride · the branched one ». Propylene Tetramer Benzelsulfonate. .

The invention relates to both the very viscous paste-like liquid detergents, commonly known as "cold-Cr" -like slurries, as well as compositions of lower viscosity, which are commonly called LD and HD- ^ eterg.
