BS ISO 21322:2020,Cosmetics — Microbiology — Testing of impregnated or coated wipes and masks.BS ISO 21322:2020 pdf free download.
BS ISO 21322:2020 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.
For technical reasons, current standards in cosmetics microbiology may not be applicable to impregnated or coated cosmetic products, such as wipes and masks, in which there is no direct access to the formulation.
Based on their product form or deliver there is a need to adapt these standards to assess the microbiological quality of these products.
