The antimicrobial protection of a product can come from many sources: chemical preservation; in

29、herent characteristics of the formulation; package design; manufacturing process. This International Standard defines a series of steps to be taken when assessing the overall antimicrobial protection of a cosmetic product. A reference method for a preservation efficacy test (challenge test) along wi

30、th evaluation criteria is also described in this International Standard. The data generated by the risk assessment (see ISO 29621) or by the preservation efficacy test, or both, are to be used to establish the level of antimicrobial protection required to minimize user risk. 4ISO 11930:2012(E) DIN E

31、N ISO 11930:2013-101 Scope 1.1 General This International Standard comprises: a preservation efficacy test; a procedure for evaluating the overall antimicrobial protection of a cosmetic product which is not considered low risk, based on a risk assessment described in ISO 29621. This International St

32、andard provides a procedure for the interpretation of data generated by the preservation efficacy test or by the microbiological risk assessment, or both. 1.2 Preservation efficacy test This test is a reference method that is to be used to evaluate the preservation of a cosmetic formulation. It appl

33、ies to cosmetic products in the market place. This test is not required for those cosmetic products for which the microbiological risk has been determined to be low (see Annex A and ISO 29621). This test is primarily designed for water-soluble or water-miscible cosmetic products and can require adap

34、tation, for example to test products in which water is the internal phase. The test described in this International Standard involves, for each test micro-organism, placing the formulation in contact with a calibrated inoculum, and then measuring the changes in the micro-organism count at set time i

35、ntervals for a set period and at a set temperature. NOTE This test can be used as a guideline to develop an in-house method during the development cycle of cosmetic products. In this case, the test can be modified or extended, or both, for example to make allowance for prior data and different varia

36、bles (microbial strains, media, incubation conditions exposure time, etc.). Compliance criteria can be adapted to specific objectives. During the development stage of cosmetic products, other methods, where relevant, can be used to determine the preservation efficacy of formulations. 1.3 Procedure f

37、or evaluating the antimicrobial protection of the cosmetic product This procedure is based on careful consideration of the following points. Results of the preservation efficacy test. Not all cosmetic products will require a preservation efficacy test (see Annex A and ISO 29621). Formulation charact

38、eristics and data provided by the microbiological risk assessment (see ISO 29621). The analysis of the microbiological risk assessment is based on an overall approach. In particular, it integrates variables such as characteristics and composition of the formulation, its production conditions, the ch

39、aracteristics of the packaging in which the formulation will be delivered to the market place, recommendations for use of the cosmetic product and, when relevant, the area of application and the targeted user population (see Annex D). 5ISO 11930:2012(E) DIN EN ISO 11930:2013-102 Normative references

47、uation of the antimicrobial protection of a cosmetic product combines the following elements (see Annex A). a) The characteristics of its formulation (see ISO 29621) or the results of the preservation efficacy test (if performed), or both. The preservation efficacy test is described in 5.1. b) The c

48、haracteristics of the cosmetic product in conjunction with the production conditions (see ISO 22716 and ISO 29621), the packaging materials and, if justified, recommendations for use of the product (see ISO 29621). This International Standard describes a procedure for the interpretation of data gene

49、rated by the preservation efficacy test (if appropriate) and by the microbiological risk assessment. 5 Preservation efficacy test 5.1 General The evaluation of the preservation of a cosmetic formulation is based on inoculation of the formulation with calibrated inocula (prepared from relevant strains of micro-organisms). The number of surviving micro-organisms is measured at defined intervals during a period of 28 days. For each time and each strain, the log reduction value is calculated
