检查一下洗髮精、清洁用品是否含「椰油酰胺」(cocamide DEA)。加州政府已视该成分为动物性致癌物质,依照当地法规,含此成分商品必须贴出警语,非营利组织「环境健康中心」曾针对未标示的厂商在加州提出诉讼。
「椰油酰胺」也称椰(基)二乙醇酰胺、「十二烷基酰乙二醇胺」,属于很常见的界面活性剂、增稠剂、起泡剂,酸硷中和剂,但在氧化氮的环境下容易形成硝基胺基酸,属于一种在动物试验中,确定引发癌症的物质。
根据世界卫生组织(WHO)「国际癌症研究署」(International Agency for Researchon Cancer, IARC)相关研究文献,已有足够证据显示该物质引起实验室老鼠癌症;但在人类身上的效应尚无足够资讯。
【Cocamide DEA And MEA】

Both cocamide DEA (diethanolamine) and MEA (monoethanolamine) are widely used to thicken the water phase of cosmetics, keep ingredients blended, and boost foaming properties. Derived from plants (typically coconut oil) or made synthetically, these ingredients have been thoroughly evaluated for safety and are permitted for use in leave-on products in concentrations up to 10%. Cocamide DEA can react with other ingredients to form harmful substances known as nitrosamines.
According to the Cosmetic Ingredient Review (CIR) Board, “To prevent the formation of possibly [harmful] nitrosamines, these ingredients should not be used in cosmetics and personal care products containing nitrosating agents.” The CIR Expert Panel concluded that “Cocamide DEA was safe as used in rinse-off products and safe at concentrations of less than or equal to 10% in leave-on products.”
