Safety Substantiation
The regulatory requirement that cosmetic manufacturers ensure and maintain adequate evidence demonstrating their products are safe under labeled or customary conditions of use. Under MoCRA, the FDA can request access to safety substantiation records during facility inspections.
Safety substantiation is the foundational principle that cosmetic products must be supported by adequate evidence of safety before being marketed. While the specific requirements vary by jurisdiction, the concept is universal across major cosmetic regulatory frameworks.
Under MoCRA in the US, responsible persons must "ensure, and maintain records supporting, adequate substantiation of safety" for each cosmetic product and each ingredient. The FDA can request access to these records during inspections. While "adequate substantiation" is not precisely defined in the statute, it generally means tests, studies, research, analyses, or other evidence that is considered sufficient by experts qualified to evaluate product safety.
In the EU, safety substantiation is formalized through the Cosmetic Product Safety Report (CPSR) within the Product Information File (PIF). A qualified safety assessor must evaluate the complete toxicological profile, calculate the Margin of Safety for each ingredient, and conclude that the product is safe.
Common elements of safety substantiation include ingredient safety data (from sources like CIR, SCCS, and peer-reviewed literature), formulation stability testing, microbiological testing, dermal absorption studies, exposure calculations, clinical testing or human repeat insult patch tests (HRIPT), and challenge testing for preservative efficacy.

Modernization of Cosmetics Regulation Act (MoCRA)
A US federal law (Public Law 117-328, Title XXXV) signed on December 29, 2022, that gives the FDA new authority over cosmetics including mandatory facility registration, product listing, adverse event reporting, safety substantiation, and recall authority.
DocumentCosmetic Product Safety Report (CPSR)
A two-part safety assessment document required within the PIF under EC 1223/2009 (Annex I). Part A compiles safety data for each ingredient; Part B is a qualified safety assessor's conclusion on whether the product is safe for human health.
OrganizationCosmetic Ingredient Review (CIR)
An independent, industry-funded expert panel that reviews and assesses the safety of ingredients used in cosmetics in the United States. CIR has reviewed over 2,000 cosmetic ingredients, and its findings are widely used for safety substantiation under MoCRA.
OrganizationScientific Committee on Consumer Safety (SCCS)
An independent scientific committee that advises the European Commission on health and safety risks of non-food consumer products, including cosmetic ingredients. SCCS opinions form the scientific basis for EU ingredient restrictions in the Cosmetics Regulation annexes.
ProcessMargin of Safety (MoS)
A quantitative measure used in cosmetic safety assessment, calculated as NOAEL divided by Systemic Exposure Dose (SED). A Margin of Safety of 100 or greater is generally considered acceptable by the SCCS, indicating the product is safe under normal conditions of use.
ProcessNo Observed Adverse Effect Level (NOAEL)
The highest dose or concentration of a substance at which no statistically or biologically significant adverse effects are observed in a toxicological study. The NOAEL is the numerator in the Margin of Safety (MoS) calculation used in cosmetic safety assessment.
