Introduction
The standard test substance is banned substances of "Hygienic Standard for Cosmetics" shall consist of not as a cosmetic raw material, component
Added to cosmetics. If technically unavoidable banned substances into cosmetics, the finished cosmetic products should follow the "Cosmetics Health Regulations
Fan "on cosmetics general requirement that under normal and reasonably foreseeable conditions of use, should not cause harm to human health.
At present, China has not yet specified the substance of limited value, the present standards, the determination of these substances in cosmetics only provide detection methods.
Cosmetics banned substances 2,4,6-trichlorophenol,
Determination of pentachlorophenol and sulfur chlorophenols
