RS ISO 18416: 2015
Cosmetics — Microbiology — Detection of Candida albicans

Abstract

This International Standard gives general guidelines for the detection and identification of the specified
microorganism Candida albicans in cosmetic products. Microorganisms considered as specified in
this International Standard might differ from country to country according to national practices or
regulations.
In order to ensure product quality and safety for consumers, it is advisable to perform an appropriate
microbiological risk analysis to determine the types of cosmetic product to which this International
Standard is applicable. Products considered to present a low microbiological (see ISO 29621) risk
include those with low water activity, hydro-alcoholic products, extreme pH values, etc.
The method described in this International Standard is based on the detection of Candida albicans in
a non-selective liquid medium (enrichment broth), followed by isolation on a selective agar medium.
Other methods may be appropriate dependent on the level of detection required.
NOTE For the detection of Candida albicans, subcultures can be performed on non-selective culture media
followed by suitable identification steps (e.g. using identification kits).
Because of the large variety of cosmetic products within this field of application, this method may
not be appropriate in every detail for some products (e.g. certain water immiscible products). Other
International Standards (ISO 18415) may be appropriate. Other methods (e.g. automated) may be
substituted for the tests presented here provided that their equivalence has been demonstrated or the
method has been otherwise shown to be suitable.
