Abstract

A composition and associated method of manufacture of a water based composition comprising a treatment agent selected from an alkanethiol, alkyl thioglycollate and dialkyl sulphide or dialkyl disulphide. The composition also includes at least one of an amphoteric, non-ionic or cationic surfactant, where the treatment agent is directly dissolved or dispersed the water containing the amphoteric, non-ionic or cationic surfactant. The composition is particularly useful for the treatment of Ag-Cu-Ge alloys. A solid polishing medium can also be included in the composition, for example, silica or precipitated chalk.
