Verifying decontamination procedures

A verification composition for application to a surface for decontamination, comprising an aqueous solution including: up to 50% of one or more solvents selected from primary/secondary alcohols, straight-chain/branched-chain alkanes (e.g., iso dodecane); up to 25% of a siloxane (e.g., cyclopentasilo...

Zusammenfassung:	A verification composition for application to a surface for decontamination, comprising an aqueous solution including: up to 50% of one or more solvents selected from primary/secondary alcohols, straight-chain/branched-chain alkanes (e.g., iso dodecane); up to 25% of a siloxane (e.g., cyclopentasiloxane); up to 15% of a surfactant (e.g., cationic, non-ionic or anionic); up to 5% of one or more humectants selected from glycerines (e.g., ethylhexylglycerin); glycols; and glycol ethers; and up to 10% of a dyestuff. The dyestuff may change colour in the presence of chlorine dioxide and may comprise an anthocyanin, anthocyanidin, or betanin (e.g., black carrot extract). Also claimed is use of the composition for verifying complete removal of the composition from a decontaminated surface. Also claimed is a method of verifying a decontamination procedure, comprising: applying to a surface the verification composition, applying the decontaminating composition to remove the verification composition, and inspecting the surface to verify that all the verification composition has been removed.
