Recently, major media have reported that the shampoo contains carcinogen-dioxane, which makes people worry about the hygiene of cosmetics. According to the "Hygienic Standards for Cosmetics" issued by the Ministry of Health in 2007, dioxane (1,4-dioxane) is a prohibited substance in cosmetics. For details, see the "Hygienic Specifications for Cosmetics" issued by the Ministry of Health in 2007. Table 2 (1) 441 pieces of cosmetics banned components. There is no relevant regulation on the content of dioxane in the raw materials, and no relevant testing methods are found in the Cosmetic Hygiene Code.
Dioxane was named 1, 4-dioxane, a colorless liquid. Slightly scented. The density is 1.0329 and the refractive index is 1.4175. The temperature of 11 ° C. The boiling point is 101.1 °C. It can be dissolved in many substances, from shower gel, detergent, moisturizer, to marine fish, roast chicken, meat products, tomatoes, ketchup, pepper, coffee and other daily foods. The human body can contact dioxane through the skin, the respiratory tract and the digestive tract. Occupational exposure, breathing air, drinking water or consumption of ingestion, washing products, cosmetics, topical medicines, agricultural and livestock products may all contain dioxane. At present, dioxane contained in cosmetics is present in shower gels and shampoos.

Therefore, the State Food and Drug Administration pointed out that in February 2007, the Ministry of Health specifically explained the concept of banned substances in the current cosmetics regulations. The banned substances specified in China's Cosmetic Hygiene Standards and Cosmetic Hygiene Regulations cannot be used as cosmetics. The raw material, that is, the component added to the cosmetic material, if it is technically impossible to avoid the banned substance as an impurity to be brought into the cosmetic, the cosmetic must meet the requirements of the Cosmetic Hygiene Standard and the Cosmetic Hygiene Specification for cosmetics, which are normal, reasonable, and Under the foreseeable conditions of use, it shall not cause harm to human health.
