Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established 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. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/ TC 106, Dentistry, Subcommittee SC 7, Oral care
products.
This third edition cancels and replaces the second edition (ISO 16408:2015), which has been technically
revised with the following changes:
— Updates according to ISO/IEC Directives for Clauses 1 and 3.
— Clause 2 were updated to include the latest version of ISO 8601-1 and to include ISO 19448.
— Clause 3 was updated to remove the definition of mouth spray as it is outside the scope of the document.
— Subclause 5.1 was clarified as ISO 28888 contains a screening method for non-fluoridated oral rinses.
— Subclause 5.2 was updated to lower the maximum fluoride per container and to reference new
subclause 7.4 and ISO 19448.
— Subclause 5.3 was updated to include a reference to USP <233> Elemental Impurities Procedures.
— Subclause 5.5 was updated to include references to USP <61>, USP <62>, and Ph.Eur. 2.6.12., include a
note regarding acceptance criteria, and to harmonize language with ISO 11609.
— Subclause 7.4 was added to include parts of removed Annex A.
— Clause 8 g) date of the test was added.
— Subclause 9.2 e) was updated to only include ingredients according to INCI.
— Subclause 9.2 g) was clarified regarding ethanol.
— Subclause 9.2 j) updated to include “and under adult supervision”.
— Annex A was removed as subclause 7.4 and ISO 19448 are now referenced for the determination of
fluoride.
