In 2021, the Cosmetic Supervision and Administration Regulation (CSAR) introduced a new mandatory pre-market requirement—cosmetic safety assessment. As stipulated in the Technical Guidelines for Safety Assessment of Cosmetics (2021), cosmetic registrants and notifiers are required to conduct safety assessments by themselves or entrusting professional institutions and submit safety assessment reports during the registration and notification process.
The establishment of the safety assessment system marks a new phase in China’s cosmetics regulation and indicates China’s efforts to align with international standards in the cosmetics field, fostering greater global integration and competitiveness.

2. Competent Authority
Currently, there are two main authorities managing safety assessment regulation in China:
National Medical Products Administration (NMPA): NMPA is established under the governance of the State Administration for Market Regulation (SAMR). It is responsible for reviewing and approving the registration and notification of cosmetics and new cosmetic ingredients (including safety assessment) in China.
National Institutes for Food and Drug Control (NIFDC): To better facilitate the implementation of the safety assessment system, China NIFDC continues to introduce a series of supporting technical guidelines, providing a data and methodological basis for safety assessment.
Part 2: Safety Assessment Requirements
1. Background
According to the Technical Guidelines for Cosmetic Safety Assessment 2021 (hereinafter referred to as the Technical Guidelines), before the registration or notification of new cosmetic ingredients or cosmetic products, the registrant or notifier is required to conduct a safety assessment on their own or through professional institutions and submit safety assessment reports. Safety assessment documents shall be updated in a timely manner as needed and kept for at least 10 years after the expiration of the last batch of marketed products. Additionally, as the Technical Guidelines outlines:
Cosmetic ingredient: Ingredient safety is the precondition of cosmetic product safety. The risk assessment of cosmetic ingredients includes the assessment of ingredients themselves and the risk substances that may be brought in.
Cosmetic product: Cosmetic products are generally recognized as a combination of various ingredients. All the ingredients and risk substances shall be assessed. If certain ingredients are confirmed to be linked with chemical and/or biological and other interactions, the risk substances generated and/or the potential safety risk arising from the interactions shall be assessed.
2. Safety Assessment Report Submission Requirements
2.1 Submission Requirements by Cosmetic Category
On April 30, 2024, the NIFDC released the Guidelines for Submission of Cosmetics Safety Assessment Dossiers. The submission guideline categorizes cosmetics into two main groups based on their risk levels, with corresponding safety assessment dossier submission requirements. The specific classification requirements are as follows.
Category I Cosmetics: Special cosmetics, infant and children’s cosmetics, and those with new cosmetic ingredients under safety monitoring period.
Category II Cosmetics: This category encompasses all other cosmetics and is subdivided based on ingredient risk and whether it should be used with instruments or tools. Please refer to the table below for specific product types.
For Category I cosmetics, safety assessment reports are mandatory. For Category II cosmetics, enterprises may either submit safety assessment reports or provide safety assessment conclusions along with supporting materials. Besides, the safety assessment reports shall be archived for future reference.
Classification | Product Type | Submission of Safety Assessment Dossiers | ||
Basic Requirements | Additional Requirements | |||
Category I Cosmetics |
| Safety assessment report | ||
Category II Cosmetics | Situation 1 | i. Cosmetics added with nano ingredients | Enterprises can choose any of the following methods: Option 1: Submit safety assessment conclusions and specific assessment materials (if any) and archive the safety assessment report for future reference. Option 2: Submit the safety assessment report | Safety assessment dossiers for nano ingredients |
ii. Non-sunscreen cosmetics added with sunscreen agents that are not listed in Table 5 of the STSC as light stabilizers | Safety assessment dossiers for light stabilizers | |||
iii. Cosmetics with claims of anti-acne, anti-wrinkle (except physical anti-wrinkle), deodorant, anti-dandruff, depilating, and exfoliation (except physical exfoliation) efficacies | Safety assessment dossiers for the functional ingredients in efficacy claims | |||
vi. Cosmetics in the form of patches or films, cosmetics containing base materials (those contain functional raw materials or pigments), or aerosols | Safety assessment dossiers for functional ingredients/colorants contained or propellants | |||
v. Cosmetics that must be used with instruments or tools (except brushes, air cushions, perming tools, etc. that only assist in the application of the cosmetics). | Safety assessment dossiers on the mechanism of action of the instrument or tool on the cosmetic product and its impact on product safety. | |||
Situation 2 | General cosmetics other than Situation 1 in Category II Cosmetics | / | ||
2.2 Timeline for Full Safety Assessment Reports
The Technical Guidelines specified that, starting from January 1, 2022, cosmetic registrants and notifiers shall submit product safety assessment documents when applying for special cosmetics registration or general cosmetics notification. Considering that there is a gap between the safety assessment capacity of China’s cosmetic industry and that of the developed countries, China’s NMPA introduced transitional measures, allowing registrants and notifiers to submit a simplified version of the product safety assessment report before May 1, 2025. With the transition period concluded, the full version is now mandatory.
Additionally, enterprises can submit their safety assessment reports through the Cosmetics Intelligent Application and Review System, per the Guidelines for Filing in the Full Version of Cosmetic Safety Assessment Materials released by the NIFDC.
3. Qualification Requirements for Safety Assessors
According to the Technical Guidelines, cosmetic safety assessors shall meet the following requirements:
Have professional knowledge of cosmetics quality and safety, e.g., medicine, pharmacy, biology, chemistry, or toxicology, etc., understand the cosmetic or ingredient production process and quality and safety control requirements, and have more than five years of relevant professional working experience;
Be able to consult and analyze literature information related to chemistry and toxicology, etc., and analyze, assess, and interpret relevant data;
Be able to analyze cosmetics’ safety fairly and objectively, and conduct safety assessments based on a comprehensive analysis of all available data and exposure conditions; and be responsible for the scientificity, accuracy, authenticity, and reliability of the assessment report.
Be able to, by receiving corresponding professional training and other ways regularly, learn related safety assessment knowledge, understand and master new safety assessment theories, techniques, and methods, and apply them in practice.

2. Full Safety Assessment Report
There are two major differences between the full and simplified versions safety assessment report. First, in the full version of the safety assessment report, the Inventory of Existing Cosmetic Ingredients in China 2021 (IECIC) is not considered as a type of evidence anymore. Second, the full version includes an assessment of both physical and chemical stability of the product (i.e., stability testing and compatibility testing with packaging materials), as well as microbiological assessment (i.e., preservative challenge testing).
Types | Simplified Version | Full Version |
Acceptable evidence | According to Technical Guidelines, evidence that can be used in the simplified version of safety assessment report:
If none of the above three types of evidence can be used for assessments:
| The Guidelines for Use of Cosmetic Ingredient Data clarifies seven types of ingredient data that cosmetic registrants and notifiers can use for safety assessments. Historical use concentration from the enterprise and IECIC is not considered a type of evidence. Accepted evidences include:
|
Additional tests | Microbiological testing Heavy metal testing Risk substance testing | Microbiological testing Heavy metal testing Risk substance testing Stability testing Compatibility testing with packaging materials Preservative challenge testing |
