防晒化妆品人体功效测试标准方法及标准样品研究进展OA

According to China's cosmetic regulations,sunscreen products are classified as special cosmetics.Their in vivo efficacy evaluation should be conducted by designated registration and filing testing institutions in compliance with the Safety and Technical Standards for Cosmetics(2015 Edition),a process that requires the use of sunscreen reference standards.This paper reviews the development of standardized methods for in vivo testing of sunscreen efficacy both in China and internationally.It compares the specifications for sunscreen efficacy reference standards among relevant International Organization for Standardization(ISO)standards,Title 21 of the United States Code of Federal Regulations(21CFR),and China's Safety and Technical Standards for Cosmetics(2015 Edition).Based on this analysis,the paper outlines the necessity and proposes an implementation pathway for developing China's own sunscreen efficacy reference standards for in vivo testing.Developing sunscreen efficacy reference standards tailored to the skin characteristics of Chinese consumers will not only fill the domestic gap in reference standards for sunscreen efficacy evaluation and improve the current standard system,but also fundamentally enhance the accuracy of product efficacy claim assessments,ensure product quality,and help overcome technical barriers associated with international standards.Ultimately,this will provide a scientific basis and technical support for the high-quality development of China's cosmetic industry.
