19、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, go
20、vernmental 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. International Standards are drafted in accordance with the rules given in the ISO/IE
21、C Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the memb
22、er bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 11609 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcom
23、mittee SC 7, Oral care products. This second edition of ISO 11609 cancels and replaces the first edition (ISO 11609:1995), which has been technically revised.

24、al soft tissues when used in accordance with the manufacturers recommendation for frequency and duration of use, nor cause any known side effects. Guidelines on assessing the claimed or implied efficacy of dentifrices for the prevention or control of oral conditions can be found through the US Food

26、arking 1 Scope This International Standard specifies requirements for the physical and chemical properties of dentifrices and provides guidelines for suitable test methods. It also specifies requirements for the marking, labelling and packaging of dentifrices. This International Standard applies to
27、dentifrices, including toothpastes, destined to be used by the public on a daily basis with a toothbrush to promote oral hygiene. Specific qualitative and quantitative requirements for freedom from biological and toxicological hazards are not included in this International Standard. These are covere
28、d in ISO 74051and ISO 10993-12. 2 Normative references The following referenced documents are indispensable for the application of this document.

31、of teeth and surrounding tissues 3.2 toothpaste any semi-solid dentifrice preparation presented in the form of a paste, cream or gel NOTE The products common constituents are abrasives, humectants, binders, surfactants, flavourings, fluorides and other agents for oral health benefits. 1) Nomenclatur

34、iven in Annex C. Other validated methods of similar sensitivity and accuracy may be used (see References 5 to 12, 28 and 29). 4.1.2 Total fluoride in a single-unit container The amount of total fluoride in a single-unit container shall not exceed 300 mg. This requirement does not apply to containers
35、 of dentifrice to be dispensed under supervised conditions in community-based caries prevention programmes such as school tooth brushing programmes. 4.2 Heavy metals The total maximum concentration shall not exceed 20 mg/kg. Test in accordance with References 13, 14 or 15, or another validated metho
36、d of similar sensitivity and accuracy. 4.3 pH When tested in accordance with 5.1, the dentifrice shall have a pH below 10,5. 4.4 Microbiology Testing for microbiological contamination shall be carried out according to References 17 to 22 and 31 to 38 or any other validated method of equivalent sensi
37、tivity, accuracy and specificity. 4.5 Abrasivity The abrasivity of the dentifrice shall not exceed the following limits for dentine: 2,5 times that of the primary reference material, if using the procedure specified in Annex A; or 2 times that of the primary reference material, if using the procedur
38、es specified in Annex B.
