Abstract
Abstract A detergent composition comprising as essential components (A) 5 - 50 parts by weight of a surfactant component consisting of a mixture of (1) 5 - 95% by weight of a water-soluble polyoxyethylene sorbitan fatty acid monoester and (2) 95 - 5% by weight of a fatty acid alkylolamide, and (B) 1 - 50 parts by weight of an organic acid salt having a chelating ability.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
129 words
A detergent composition consisting essentially of A. from 5 to 50 parts by weight of surfactant component consisting essentially of 1. from 5 - 95% by weight of water-soluble polyoxyethylene sorbitan monoester of fatty acid having 8 to 22 carbon atoms and containing from 5 to 50 oxyethylene units in the molecule, 2. the balance being fatty acid alkylolamide selected from the group consisting of diethanolamides and polyoxyethylene monoethanolamides having 10 to 20 oxyethylene units in the molecule, of fatty acids having 8 to 22 carbon atoms, and B. from 1 to 50 parts by weight of an organic acid salt having a chelating ability selected from the group consisting of the alkali metal and ammonium salts of gluconic acid, citric acid, malic acid, tartaric acid, and lactic acid.
