Description / Abstract:
This International Standard gives general guidelines for the
detection and identification of the specified microorganism
Escherichia coli 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, so as to determine the types of cosmetic products 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.
This International Standard specifies a method that is based on
the detection of Escherichia coli in a nonselective liquid
medium (enrichment broth), followed by isolation on a selective
agar medium. Other methods may be appropriate depending on the
level of detection required.
NOTE For the detection of Escherichia coli, 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 might not be suited to some
products in every detail (e.g. certain water-immiscible products).
Other International Standards may be appropriate. Other methods
(e.g. automated) can be substituted for the test presented here
provided that their equivalence has been demonstrated or the method
has been otherwise validated.
