PURPOSE: To obtain a high concn. one-component type alkali washing agent composition which is capable of compounding a hardly soluble component, high in washing property, foam-inhibitive, low COD, low cost and stable by making the washing agent contain an alkali agent and the arom. compd. having a specified number polar group in a specified amount.
CONSTITUTION: This high concn. one-component type alkali washing agent composition is compounded with 10-35wt.% alkali agent (based on Na2O) and 0.1-20wt.% arom. compd. having 2-50 number polar group in one molecule, and moreover, a hardly soluble chelating agent, alcohol, surfactant, faty acid, etc., in a prescribed amount if necessary, and the composition satisfies high washing property etc., required to the washing agent. This composition is used after dilution to the concn. of 0.1-10% (baseing on Na2O) alkali agent. And, this composition is produced by mixing under stirring with other component including the arom. compd. to ≥10% (based on Na2O) alkali agent in excess state of alkali.
