25、 is to obtain sufficient information to enable the manufacturer to establish an appropriate shelf-life and identify any unique storage conditions required to appear on the labelling of the product.The quality of a contact lens care product is determined by its content of active ingredient(s), its pu
26、rity, and its physicochemical and microbiological properties. It is important to take into account the possible interaction of the container/closure with the contents.The stability studies are intended to ascertain how the quality of a product varies as a function of time and under the influence of
27、a variety of environmental factors.On the basis of the information obtained, storage conditions are recommended, which will guarantee the maintenance of the quality of the product in relation to its safety, performance, and acceptability throughout the proposed shelf-life.The design of the finished
28、product stability studies for a care product is based on the knowledge obtained from studies on the active ingredient(s) and from the development studies.

33、the terms and definitions given in ISO 18369-1 apply.4 General requirements4.1 The specified shelf-life of the contact lens care product shall be based on the evaluation of the results of stability studies.4.2 Analytical methods that have been validated and are stability indicating shall be used to
34、assay for active ingredients. Validation includes, but is not limited to, being able to differentiate between the active ingredient and its degradation products. The test methods used shall be described in full.5 Determination of finished product stability5.1 ObjectiveThe objective of stability test
35、ing on contact lens care products is to provide data for determining the time period during which the product performance characteristics are maintained and to define appropriate storage conditions.The design of the stability tests is based on the known properties of the active ingredient(s), the pr
36、operties of the chosen formulation, and the recommendations for use of the product.The relevant assay methods shall be determined prior to the start of the stability testing.INTERNATIONAL STANDARD ISO 13212:2014(E) ISO 2014 All rights reserved 1BS EN ISO 13212:2014ISO 13212:2014(E)The specifications
37、 proposed from the time of manufacture to the end of the proposed shelf-life shall reflect, as far as possible, the results of the stability studies, particularly in relation to any parameters which could have a bearing on performance and safety and on product acceptability.5.2 Study methods5.2.1 Ge
38、neralBefore starting stability studies, a suitable testing plan should be set up, taking into consideration the properties of the active ingredient(s) as well as the proposed mode of action of the care product.5.2.2 Real-time studiesThese studies should be carried out under a range of controlled tes
39、t conditions, when applicable, which will enable the shelf-life and the storage requirements which are to appear on the product container label/package insert to be defined. This will normally include studies which are intended to allow the properties of the product at temperatures between 20 C and
40、30 C to be evaluated. However, 25 C 2 C should be used as the mean kinetic testing temperature.Relative humidity should be controlled for all products that are not in hermetically sealed containers. In the case of tablets, high humidity conditions should be considered. In the case of aqueous liquids
41、, low humidity conditions should be considered (see Annex A).For each study, the mean temperature, the ranges of temperature, and mean humidity, if applicable, shall be stated in the stability report.These studies are intended to support the initial shelf-life request and, for shelf-life extensions,
42、 any changes that could significantly impact the safety and performance of the product (e.g. certain changes in formulation, packaging materials, or manufacturing methods).NOTE Real-time studies are performed in conjunction with accelerated ageing studies to establish an initial shelf-life.5.2.3 Stu
43、dies under varying storage conditionsThese studies shall be carried out to provide important additional information. They can fulfil a number of objectives, such as supporting the initial shelf-life request, by complementing the limited results of the early real-time studies because decomposition, i
44、f it occurs, is likely to be accelerated, producing useful data at an early stage of development, demonstrating the effects of adverse storage in the packaging and product, and enabling storage conditions and suitable labelling to be provided, and supporting a request to extend the shelf-life.The va
45、rious test conditions should be stated. Depending on the nature and objectives of the stability study, the following points might need to be considered:a) various test temperatures: three or more, particularly if long-term real-time data are unavailable. In addition, the effect of low temperatures m
46、ight need to be considered, such as below 15 C (freezer), 2 C to 8 C (refrigerator) and freezethaw cycling;b) high humidity: relative humidity up to 75 % 5 % (see Annex A). Storage under high humidity conditions applies particularly to solid dosage forms. For products such as solutions, suspensions,
47、 etc. contained in packs designed to provide a permanent barrier to water loss, storage under high humidity is not necessary. However, low humidity can have an adverse effect on products packaged in semi-permeable containers;2 ISO 2014 All rights reservedBS EN ISO 13212:2014ISO 13212:2014(E)c) eleva
48、ted temperature and humidity in combination: e.g. temperature of 40 C associated with a relative humidity of up to 75 %, possibly with the effects of cycling between different temperatures and humidities;d) since most contact lens care products are water-based, relative humidity of 40 % or less (for
49、 example, 25 C and 40 % relative humidity) should be considered (see Annex A);e) light: either natural daylight or defined artificial illumination (see Annex A).5.3 Description of the product under study5.3.1 Number and nature of the batches testedThe number of batches tested shall be stated with the batch number, details of the composition, date of manufacture, size of the batch and the name of the manufacturer of the active ingredient(s) used.
