Abstract
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.
Claims3
A detergent composition which is substantially free of polyphosphates and contains at least one anionic surface active agent selected from the group consisting of sodium alkyl sulfate, sodium alkylbenzenesulfonate, sodium alkylpolyether sulfate and sodium long-chain alpha-olefinsulfonate, or at least one non-ionic surface active agent selected from the group consisting of polyoxyethylene alkyl ether, polyoxyethylene long-chain fatty acid ester and polyoxyethylenepolyoxypropylene block copolymer, and a builder, wherein:
- said builder comprises
- 5 to 50 parts by weight of a salt of imido-bis-sulfuric acid represented by the general formula of (M.sup.1 SO.sub.3).sub.2 NM.sup.2, wherein M.sup.1 represents sodium, potassium, lithium or ammonium and M.sup.2 represents a hydrogen atom, sodium, potassium, lithium or ammonium,
- 0.05 to 30 parts by weight of at least one salt of a saturated or unsaturated fatty acid selected from the group consisting of the sodium, potassium and ammonium salts thereof, said saturated or unsaturated fatty acid having 12 to 18 carbon atoms, and
- 0.1 to 15 parts by weight of at least one salt of a polycarboxylic acid selected from the group consisting of sodium ethylenediamminetetraacetate and sodium nitrilotriacetate.
