18、O 29621:2017(E)ForewordISO (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
19、 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)
20、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 note

25、17ISO 29621:2017(E)IntroductionEvery cosmetic manufacturer has a dual responsibility relative to the microbiological quality of its products. The first is to ensure that the product, as purchased, is free from the numbers and types of microorganisms that could affect product quality and consumer hea
26、lth. The second is to ensure that microorganisms introduced during normal product use will not adversely affect the quality or safety of the product.The first step would be to perform a microbiological risk assessment of the product to determine if the cosmetic microbiological International Standard
27、s apply.Microbiological risk assessment is based on a number of factors generally accepted as important in evaluating the adverse effects on product quality and consumer health. It is intended as a guide in determining what level of testing, if any, is necessary to assure the quality of the product.
28、 Conducting a microbiological risk assessment involves professional judgment and/or a microbiological analysis, if necessary, to determine the level of risk.The nature and frequency of testing vary according to the product. The significance of microorganisms in non-sterile cosmetic products is to be
29、 evaluated in terms of the use of the product, the nature of the product and the potential harm to the user.The degree of risk depends on the ability of a product to support the growth of microorganisms and on the probability that those microorganisms can cause harm to the user. Many cosmetic produc
30、ts provide optimum conditions for microbial growth, including water, nutrients, pH and other growth factors. In addition, the ambient temperatures and relative humidity at which many cosmetic products are manufactured, stored and used by consumers, will promote growth of mesophiles that could cause
31、harm to users or cause degradation of the product. For these types of products, the quality of the finished goods is controlled by applying cosmetic good manufacturing practices (GMPs) (see ISO 22716) during the manufacturing process, using preservatives and conducting control tests using appropriat
32、e methods.The likelihood of microbiological contamination for some cosmetic products is extremely low (or non-existent) due to product characteristics that create a hostile environment for survival/growth of microorganisms. These characteristics are elaborated in this document. While the hazard (adv
33、erse effects on product quality and consumer health) may remain the same for these products, the likelihood of an occurrence is extremely low. These products identified as “hostile” and produced in compliance with GMPs pose a very low overall risk to the user.Therefore, products that comply with the
34、 characteristics outlined in this document do not require microbiological testing.This document gives guidance to cosmetic manufacturers and regulatory bodies to determine when, based on a “risk assessment,” the application of the microbiological International Standards for cosmetics and other relev
35、ant methods is not necessary.

43、may occur during manufacturing and/or intended use by the consumer.Note 2 to entry: A product whose packaging prevents the ingress of microorganisms is considered a microbiological low-risk product during its use.Note 3 to entry: The inclusion of preservatives or other antimicrobial compounds in a f
44、ormulation by itself would not necessarily constitute a low-risk product.4 Risk assessment factors4.1 GeneralA number of product characteristics needs to be evaluated when performing a microbial risk assessment to determine if that product should be subjected to the published microbiological Interna
45、tional Standards for cosmetics or other relevant methods. These characteristics include the composition of the product, the production conditions, packaging and a combination of these factors.4.2 Composition of the product4.2.1 General characteristicsProducts with certain physico-chemical characteri
46、stics do not allow the proliferation of microorganisms of concern to cosmetic products. Any number of physico-chemical factors or combinations thereof in a product can create a hostile environment that will not support microbial growth and/or survival. Combinations of sub-lethal factors will increas
47、e the hostility of the environment and increase the lag phase. If the environment is hostile enough, the lag phase will be extended to infinity and therefore cause cell death. Combinations of lethal factors will cause rapid cell death. The following factors should be considered in determining whethe
48、r cosmetic products present a hostile environment.4.2.2 Water activity, aw, of formulationWater is one of the most important factors controlling the rate of growth of an organism. It is not the total moisture content that determines the potential for growth but the available water in the formulation
49、. The metabolism and reproduction of microorganisms require the presence of water in an available form. The most useful measurement of water availability in a product formulation is water 2 ISO 2017 All rights reservedBS EN ISO 29621:2017ISO 29621:2017(E)activity, aw. Water activity is defined as the ratio of the water vapour pressure of the product to that of pure water at the same temperature see Formula (1):appnnnw=+()0212(1)wherep is the vapour pressure of the solution;p0is the vapour pressure of pure water;n1is the number of
