Foreword
ISO (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 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) 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 noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not

ISO/TR 19838:2016(E)
Introduction
Every 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 health. This is generally ensured
by applying cosmetic good manufacturing practice (GMP) (see ISO 22716) during the manufacturing
and packaging operations and, if necessary, by using microbial content tests on finished products.
— The second is to ensure that microorganisms introduced during normal product use will not
adversely affect the quality or safety of the product. This is generally ensured by conducting
preservation efficacy tests (or challenge tests) during the development stage of the new product.
In order to ensure product quality and safety for consumers, it is advisable that an appropriate
microbiological risk analysis be performed to determine the types of cosmetic products to which this
Technical Report would be applicable.
— Products considered to present a low microbiological risk are described in ISO 29621. These
products identified as “hostile” and produced in compliance with GMP pose a very low overall risk
to the user. Therefore, products that comply with the characteristics outlined in ISO 29621 do not
require microbiological testing including both challenge test and end product testing.
— For those products which are not considered “hostile”, the microbiological quality has to be
assessed by conducting tests with appropriate methods. ISO TC 217 provides a comprehensive set
of standards to assess the antimicrobial preservation of cosmetic products and the microbiological
quality of finished products (methods and limits). Manufacturers can decide not to test if they can
demonstrate that their products comply with those requirements specified in ISO 17516 and/or
ISO 11930.
