There is provided a novel detergent composition containing no phosphorus component, which comprises an anionic and/or nonionic synthetic surfactant(s) and an effective amount of a mixture in a specified proportion consisting essentially of an imido-bis-sulfate salt, a palmitate salt and an N,N-bis(carboxymethyl)glutamate salt and/or a salt of N,N-bis(carboxymethyl)phenylalanine. The detergent composition exhibits the detergency at least equivalent to conventional detergent compositions containing 20% or more of sodium tripolyphosphate and causes no pollution problems.

Phosphate-free detergent composition

A detergent composition containing an anionic surface active agent and/or a nonionic surface active agent, characterized by containing as a builder 5 to 50% by weight of a salt of imido-bis-sulfuric acid, 0.05 to 30% by weight of a salt of a saturated or unsaturated fatty acid or a mixture thereof and 0.1 to 15% by weight of a salt of a polycarboxylic acid or a mixture thereof.

Detergent composition

A composition including a silicate, imidodisulfonic acids and/or the salts thereof is disclosed. This composition is useful as grouting agent.

Grouting materials for consolidation of soils

A self-hardening composition for making sand molds comprising a molding sand, a water glass as a binder and at least one salt of imidodisulfonic acid as a hardener.
