24、 provide health and/or cosmetic benefits.This International Standard specifies the chemical and physical properties of oral rinses. Common labelling aspects are also specified in order to enhance international understanding and trade.4DIN EN ISO 16408:2015-12 EN ISO 16408:2015 (E) 1 ScopeThis Intern
25、ational Standard specifies physical and chemical requirements and test methods for oral rinses. It also specifies the accompanying information such as the manufacturers instructions for use, marking, and/or labelling requirements.This International Standard is not applicable to other delivery system
26、s (e.g. mouthsprays, foams, powders). It is not intended to describe regulatory aspects, e.g. methods of prescription.This International Standard is not applicable to oral rinses available by prescription only.2 Normative referencesThe following documents, in whole or in part, are normatively refere

31、 by the user as follows: Type 1: ready-for-use solutions; Type 2: concentrated solutions for use after dilution with water; Type 3: solutions for use after mixing.5 Requirements5.1 pH valueOral rinses shall have a pH value between 3,0 and 10,5. If the pH value of an oral rinse is below 5,5 it shall
32、pass a screening test as specified in ISO 28888.Test the pH value in accordance with 7.1 and 7.3.NOTE At the time of development of this International Standard, there is no evidence that oral rinses with pH values between 5,5 and 10,5 promote enamel erosion.5.2 Total fluoride concentration and maxim
33、um amount of fluorideThe total fluoride concentration of one container of oral rinse of Type 1 shall not exceed a mass fraction of 0,15 %.The maximum amount of ionic fluoride per single container shall not exceed 125 mg.Test fluoride-containing oral rinses in accordance with Annex A.As an alternativ
34、e one of the procedures given in ISO 11609, Annex C,3or other validated method of similar sensitivity and accuracy, may be use, for example References 13 or 14.5.3 Unintended heavy metalsThe maximum total concentration of unintended heavy metals in oral rinses shall not exceed 20 mg/kg.Test in accor
35、dance with a validated method, for example References 15, 16, 17 or 22.If this is not suitable other method of similar sensitivity and accuracy shall be used.NOTE There may be other potentially dangerous elements, especially arsenic, which are not covered by this International Standard as currently
36、no analytical test methods and no effect levels are consented.5.4 Compatibility with oral tissuesOral rinses shall not cause irritation or damage to the oral hard and/or soft tissue, when used in accordance with the manufacturers recommendation for frequency and duration of use and experience with k
37、nown side effects.Specific qualitative and quantitative requirements for freedom from biological hazards are not included in this International Standard, but it is recommended that reference be made to ISO 7405 and ISO 10993-1 when assessing possible biological or toxicological hazards.6DIN EN ISO 1

N1)Testing for microbial contamination shall be carried out according to a validated method, for example Refer
39、ences 6, 7, 8, 9, 10, 11 or 12.5.6 Stability against ageingOral rinses shall show no signs of deterioration, such as agglomeration or change in clarity, after being subjected to the determination of stability to ageing procedure specified in 7.4.5.7 Container and/or dispensing systemThe container an
40、d/or dispensing system shall neither contaminate nor permit contamination of the oral rinse inside such that it will affect its compliance with the requirements of Clause 5 after being subjected to the determination of stability to ageing described in 7.4.5.8 Readily fermentable carbohydratesOral ri
41、nses shall not contain readily fermentable carbohydrates.Compliance shall be established by the absence of such compounds in the complete formula, or by performing tests in accordance with commonly used analytical methods.6 SamplingThe oral rinses used for testing shall be representative of actual m
42、anufactured oral rinse and shall not be altered in any way.Eight containers of oral rinses from the same manufacturing tracking code (e.g. batch code, lot number) shall be tested before the determination of stability to ageing (see 7.4).7 Test methods7.1 GeneralAll tests shall be performed before an
43、d after the stability to ageing test (7.4).7.2 Visual inspectionBefore and after agitation, examine the oral rinse under a bright light with normal visual acuity without magnification.7.3 Determination of pH valueTest the pH value of the oral rinse in its intended concentration for use.Determine the
44、 pH value of the solution using a calibrated pH-meter with an accuracy of 0,1 mV.7.4 Determination of stability against ageing7.4.1 TestOne of the following two tests shall be performed.a) Accelerated testStore the oral rinse at (40 2) C for 3 months at (75 5) % relative humidity or under such condi
45、tions of time and temperature as will simulate storage at room temperature for 30 months.7DIN EN ISO 16408:2015-12EN ISO 16408:2015 (E)5.5 Microbial contaminationThe microbial contamination of oral rinses shall not exceed 100 colony-forming units (CFU) per gram.

46、s.b) Real time testStore the oral rinse at (23 2) C at (60 15) % relative humidity for 30 months or for the period indicated by the expiry date listed on the product label see 9.2 n).7.4.2 ComplianceExamine by visual inspection (7.2) of the oral rinse if requirement 5.6 is fulfilled.7.5 Pass/fail cr
47、iteriaUnless otherwise noted, if none of the samples fails, the oral rinse passes.If one sample does not meet the minimum requirement, another eight samples shall be tested. If no more samples fail, the oral rinse passes. If a total of two or more samples of the 16 samples fail, the oral rinse fails
48、.8 Test reportThe test report shall include at least the following information:a) the name and address of the organization responsible for the test report;b) a reference to this International Standard, i.e. ISO 16408;c) the manufacturers tracking code (e.g. batch code, lot number);d) the test result
49、s and the method of determination used;e) any unusual features noted during the determination;f) if the oral rinse passed or failed the test.9 Accompanying information9.1 Manufacturers instructions for useThe manufacturers or suppliers instructions for use accompanying the oral rinse shall contain at least the following information:a) information specified in 9.2, with the exception of d), f), and n), and
