NBN ISO 21322:2021

This document gives guidance for the enumeration and/or detection of microorganisms present in a
cosmetic product that is impregnated or coated onto a substrate (i.e. wipes and masks) where sampling
and microbiological influence of the manufactured product presents particular challenges in terms of
microbiological sampling and testing.
The principle of this document can also be applied to test similar products (e.g. cushion, impregnated
sponge, etc.) or applicators (e.g. brush, puff, sponge, etc.) with modification of the procedure as
appropriate.
