(Main)Soaps -- Determination of chloride content -- Titrimetric method
Soaps -- Determination of chloride content -- Titrimetric method
The determination is carried out by argentometric titration after decomposition of a test and separation of fatty acids by filtration. The method is applicable to soaps having a chloride content, expressed as sodium chloride, equal to or greater than 0,1 % (m/m). It cannot be applied to componounded products.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bedies). The work of developing International
Standards is carried out through ISO technical committees. Every member body
interested in a subject for which a technical committee has been authorized has the
right to be represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council.
International Standard ISO 457 was developed by Technical Committee ISO/TC 91,
Surface active agents, and was circulated to the member bodies in June 1982.
lt has been approved by the member bodies of the following countries :
Australia
Germany, F. R. Romania
