The Modernization of Cosmetics Regulation Act (MoCRA) represents the most significant update to U.S. cosmetic regulations in decades.
Under MoCRA, the Responsible Person typically the manufacturer, brand owner, or distributor must maintain scientific evidence supporting product safety.
Key compliance requirements include:
Safety substantiation documentation
Cosmetic Good Manufacturing Practices (GMP)
Facility registration
Product listing
Adverse event reporting
Ingredient record maintenance
Growing regulatory attention is also focused on:
PFAS (Per- and Polyfluoroalkyl Substances)
Fragrance allergens
Talc testing
Heavy metal contamination
European Union – Cosmetic Regulation (EC) No. 1223/2009
The EU Cosmetic Product Safety Report (CPSR) remains one of the world's most comprehensive cosmetic safety frameworks.
The CPSR consists of two sections:
Part A – Cosmetic Safety Information
This section includes:
Ingredient composition
Physical and chemical properties
Microbiological quality
Stability studies
Packaging compatibility
Exposure assessment
Toxicological profiles
Part B – Cosmetic Safety Assessment
A qualified safety assessor evaluates the collected scientific data and provides a formal conclusion confirming product safety.
Recent regulatory updates also introduce tighter restrictions on:
CMR (Carcinogenic, Mutagenic, or Reprotoxic) substances
Formaldehyde-releasing preservatives
Certain UV filters
Fragrance allergens
South Korea and China
Asia's cosmetic industry is also adopting stricter regulatory standards.
South Korea (MFDS)
The Ministry of Food and Drug Safety (MFDS) has introduced cosmetic safety assessment requirements closely aligned with the European regulatory framework.
Manufacturers are expected to provide comprehensive toxicological evaluations before market approval.
China (NMPA)
The National Medical Products Administration (NMPA) requires detailed ingredient safety information, toxicological data, and scientific documentation for both general and special-use cosmetics.
Companies entering the Chinese market must demonstrate ingredient safety through validated scientific evidence and regulatory documentation.
Key Components of a Cosmetic Product Safety Assessment
A cosmetic safety assessment follows a structured toxicological workflow designed to evaluate consumer exposure and establish safe usage limits.
Step 1: Collect Ingredient Safety Information
Every ingredient included in a cosmetic formulation is evaluated based on:
Purity
Impurities
Manufacturing process
Toxicological profile
Historical safety data
Regulatory restrictions
Reliable scientific literature, SCCS opinions, published toxicological databases, and computational toxicology tools are commonly used during this stage.
Step 2: Calculate Systemic Exposure Dose (SED)
The Systemic Exposure Dose (SED) estimates how much of an ingredient is absorbed into the body during normal product use.
Several factors influence SED calculations, including:
Daily product usage
Ingredient concentration
Dermal absorption rate
Frequency of application
Consumer body weight
Accurate exposure assessment forms the foundation of cosmetic toxicological risk assessment.
Step 3: Determine the Point of Departure (POD)
Toxicologists identify a suitable Point of Departure (POD) using available toxicological evidence.
Common toxicological endpoints include:
NOAEL (No Observed Adverse Effect Level)
BMDL (Benchmark Dose Lower Confidence Limit)
When published toxicological information is limited, experienced regulatory toxicology experts such as Auxochromofours apply scientifically accepted approaches, including read-across methodologies and weight-of-evidence assessments, to generate robust safety justifications that support global regulatory compliance.
Step 4: Calculate the Margin of Safety (MoS)
The Margin of Safety (MoS) compares estimated human exposure with established toxicological safety thresholds.
An MoS of 100 or greater is generally considered acceptable, providing adequate protection for:
Human variability
Animal-to-human extrapolation
Sensitive consumer populations
Margin of Safety calculations remain one of the most important components of cosmetic product safety reports.
Supporting Documentation Required for Cosmetic Compliance
A cosmetic safety assessment must be supported by a complete Product Information File (PIF) or equivalent regulatory dossier.
Essential documentation includes:
ISO 22716 Good Manufacturing Practices (GMP)
ISO 22716 certification demonstrates that cosmetic products are manufactured under internationally recognized Good Manufacturing Practices, ensuring consistent quality and product safety.
Preservative Efficacy Testing (PET)
Also known as a Challenge Test, Preservative Efficacy Testing verifies that cosmetic formulations remain protected against microbial contamination throughout their intended shelf life.
Stability Testing
Stability studies evaluate whether cosmetic products maintain their:
Physical appearance
Chemical composition
Performance
Microbiological quality
under normal storage conditions.
Packaging Compatibility Studies
Packaging materials can interact with cosmetic formulations over time.
Manufacturers must demonstrate that packaging does not release harmful substances such as:
Heavy metals
Plasticizers
Phthalates
Chemical contaminants
Comprehensive packaging compatibility studies help ensure product stability and long-term consumer safety.
