Full title and description

ISO/TR 18811:2018 — Cosmetics — Guidelines on the stability testing of cosmetic products. This Technical Report provides guidance and a review of readily available bibliographic references to support the assessment of cosmetic product stability; it is intended as a technical/scientific framework to help manufacturers identify suitable methods for stability assessment without prescribing specific test conditions, parameters or acceptance criteria.

Abstract

ISO/TR 18811:2018 reviews existing guidelines and bibliographic sources relevant to stability testing of cosmetics and presents them as a reference framework. The report clarifies that, because of the diversity of cosmetic formulations and storage/use conditions, stability protocols (test methods, specifications and test conditions) must be defined and justified by manufacturers rather than being mandated by the report.

These bibliographic and bibliometric details are taken from the ISO catalogue entry for ISO/TR 18811:2018.

Scope

Defines the purpose and intended use of the Technical Report: to give guidance on approaches to stability testing of cosmetic products by reviewing publicly available guidelines and references. The document explicitly does not set test conditions, stability criteria or parameters because such specifics depend on product type, formulation and intended storage/use conditions; responsibility for defining and justifying the stability protocol rests with the manufacturer.

Key topics and requirements

• Overview of available guidance and bibliographic references for cosmetic stability testing.
• Framework for selecting appropriate stability assessment methods for different types of cosmetic products.
• Emphasis that stability testing conditions, parameters and acceptance criteria are not prescribed and must be justified by manufacturers.
• Considerations for storage, transport and use conditions that affect product stability planning.
• Recommendations for documenting and rationalizing stability protocols to support product quality and shelf-life claims.

Key topics are summarized from the report's stated purpose and content.

Typical use and users

Used by cosmetic formulators, quality assurance and regulatory affairs teams, stability laboratory personnel, and contract testing laboratories. Typical uses include developing and justifying product-specific stability test protocols, compiling bibliographic references for stability assessment, and informing internal SOPs and product dossiers submitted to regulators or third-party certifiers.

Related standards

Commonly referenced standards and deliverables in the cosmetics quality and claims space include ISO 22716 (Cosmetics — Good Manufacturing Practices — Guidelines on GMP) and ISO 16128 (Guidelines on technical definitions and criteria for natural and organic cosmetic ingredients and products). These documents address complementary aspects (manufacturing quality and ingredient classification) that pair with stability considerations during product development and market authorization.

FAQ

Q: What is this standard?

A: ISO/TR 18811:2018 is a Technical Report from ISO providing guidance and a bibliographic review to help manufacturers plan and justify stability testing for cosmetic products.

Q: What does it cover?

A: It reviews available guidelines and references relevant to cosmetic stability testing and offers a framework to identify suitable assessment methods. It does not prescribe test conditions, parameters or acceptance criteria.

Q: Who typically uses it?

A: Cosmetic formulators, QA/regulatory teams, stability laboratories, and contract testing organizations use it when designing, documenting and defending product-specific stability protocols.

Q: Is it current or superseded?

A: As of its ISO catalogue entry, ISO/TR 18811:2018 is the published Technical Report (Edition 1, 2018). Users should check national/ISO catalogues or national standards bodies for any later confirmations, revisions or amendments before relying on it for regulatory submissions.

Q: Is it part of a series?

A: It is an ISO Technical Report produced under ISO/TC 217 (Cosmetics) and sits alongside other ISO deliverables for cosmetics (for example ISO 22716 and ISO 16128) that address manufacturing practices and ingredient definitions. It is not a numbered series like ISO 188xx beyond its own designation.

Q: What are the key keywords?

A: Stability testing, shelf life, cosmetics, stability protocol, ISO/TC 217, technical report, product dossier, storage conditions.
