Detergents/ disinfectants based on quartenary ammonium compounds — Specification; (28 page(s), in English)

This standard specifies requirements for two types of detergent-disinfectant based on quaternary ammonium compounds and other chemical agents (such as compatible surface-active agents and phosphates), that are miscible with water and intended for use on inanimate surface that are free from excessive dirt. The standard is intended for the evaluation of detergent-disinfectants based on quaternary ammonium compounds for general use. Quaternary ammonium compounds are organically substituted ammonium compounds in which the nitrogen compound has a valence of five. Four of the substituted radicals are alkyl or heterocyclic radicals and the fifth is an anion. Examples include cetrimide, benzalkonium chloride and benzethonium chloride.

NOTE 1 Using this specification, it is not possible to determine the bactericidal activity of the undiluted product. Some dilution is always produced by the addition of inoculum, hard water and sterile skimmed milk.

NOTE 2 If a product complies with the test requirements, it can be considered to be bactericidal, but it should not necessarily be inferred that the product is a suitable detergent-disinfectant for a defined purpose.
