Detergent composition and chemical-mechanical polishing composition comprising an alkanol hydroxylamine and polyglycerol derivative mixture

A detergent composition comprising:

• A) an alkanol hydroxylamine compound represented by General Formula (1)
• wherein:
• i) Ra1 and Ra2 are the same or different and each represents a hydrogen atom or an alkyl group having from 1 to 10 carbons that may have from 1 to 3 hydroxyl groups, with the proviso that Ra1 and Ra2 are not simultaneously hydrogen atoms;
• and
• ii) a total number of hydroxyl group or groups present in Ra1 and Ra2 is not 0;
• B) a basic compound besides the alkanol hydroxylamine compound;
• C) a polyglycerol derivative represented by General Formula (3):
• where Rc represents a hydrogen atom or a hydrocarbon group that may have a hydroxyl group, and n is an integer from 2 to 40:
• D) a chelating agent represented by General Formula (4):
• where X represents a carboxyl group or a phosphonic acid group;
• Rd and Re are the same or different and each represents a hydrogen atom or a monovalent hydrocarbon group that may have a substituent;
• and Rf represents a divalent hydrocarbon group that may have a substituent;
• and any two of Rd to Rf may bond to each other to form a ring together with an adjacent nitrogen atom;
• and
• E) from 0.01 to 2.0 wt. % of an additional component besides the alkanol hydroxylamine compound, the basic compound, the polyglycerol derivative, and the chelating agent;
• wherein the composition has a pH of 10 to 13, and the weight ratio of the alkanol hydroxylamine compound to the basic compound (alkanol hydroxylamine compound/basic compound) in the detergent composition is from 1 to 10.
