Full title and description

ISO 16212:2017/Amd 1:2022 — Cosmetics — Microbiology — Enumeration of yeast and mould — Amendment 1. This one‑page amendment updates and applies corrections/clarifications to the ISO 16212:2017 test method for enumeration of yeasts and moulds in cosmetic products.

Abstract

ISO 16212:2017 provides general guidelines for enumeration of yeast and moulds present in cosmetics by counting colonies on selective agar medium after aerobic incubation. Amendment 1 (2022) is issued to modify, clarify or correct elements of the 2017 document; the amendment itself is published as a short (1‑page) update to the original standard.

Scope

This amendment applies to ISO 16212:2017 and provides targeted corrections and clarifications to the procedure for enumeration of yeasts and moulds in cosmetic products. The base standard covers sample preparation, use of selective agar media, aerobic incubation, colony counting and reporting; the amendment refines or corrects specific points of that method (details are contained in the published amendment text).

Key topics and requirements

• Clarifications and corrections to the ISO 16212:2017 enumeration method (procedural or editorial updates introduced by the 2022 amendment).
• Main method elements affected: sample handling and preparation, selective agar/media guidance, incubation conditions (aerobic), colony counting and reporting formats as defined in ISO 16212:2017.
• Applicability notes: guidance on product types for which the method is appropriate and where alternative methods or validations may be required (e.g., water‑immiscible products).

Typical use and users

Microbiology and quality‑control laboratories in the cosmetics industry, regulatory laboratories, product safety specialists and standards bodies use ISO 16212 and its amendment to ensure consistent enumeration of yeast and moulds in cosmetic products and to interpret results for product release, shelf‑life and safety assessments.

Related standards

Documents commonly referenced alongside ISO 16212 include ISO 29621 (guidance on microbiological risk and products with low microbiological risk), ISO 21148 and other ISO/TC 217 publications and technical reports on cosmetic microbiology and test method application. Users often consult the base ISO 16212:2017 together with this amendment.

FAQ

Q: What is this standard?

A: ISO 16212:2017 is an ISO international standard specifying a plate‑count method for enumeration of yeasts and moulds in cosmetic products; ISO 16212:2017/Amd 1:2022 is a one‑page amendment that updates or clarifies parts of the 2017 standard.

Q: What does it cover?

A: It covers procedures for preparing samples, using selective agar media, aerobic incubation conditions and counting/reporting colonies of yeasts and moulds present in cosmetics. The 2022 amendment makes targeted corrections or clarifications to that procedure.

Q: Who typically uses it?

A: Cosmetic manufacturers' QC laboratories, contract testing laboratories, regulatory testing bodies and product safety assessors who need standardized, reproducible methods for yeast and mould enumeration.

Q: Is it current or superseded?

A: The amendment (ISO 16212:2017/Amd 1:2022) was published in August 2022 and applies to the current ISO 16212:2017 document; it does not supersede the 2017 standard but modifies it (the base standard remains the normative document as amended).

Q: Is it part of a series?

A: The standard is maintained by ISO/TC 217 (Cosmetics) and is related to other cosmetic microbiology standards and technical reports (for example ISO 29621 and other ISO/TC 217 outputs).

Q: What are the key keywords?

A: Cosmetics, microbiology, yeast, mould, enumeration, colony count, selective agar, incubation, ISO 16212, amendment 2022.
