        basic introduction

        Phthalates, also known as phthalates, abbreviated PAEs, are the general term for esters formed from phthalic acid. (In short, it is a kind of plasticizer) When used as a plastic plasticizer, it generally refers to an ester of phthalic acid and a 4-15 carbon alcohol. Among them, dioctyl phthalate is the most important variety. Phthalates are a class of chemicals that can soften and interfere with the endocrine system.

        Phthalates are mainly used in polyvinyl chloride materials, making polyvinyl chloride change from hard plastic to elastic plastic, which acts as a plasticizer. It is widely used in hundreds of kinds of toys, food packaging materials, medical blood bags and hoses, vinyl floors and wallpapers, cleaners, lubricants, personal care products (such as nail polish, hair sprays, soaps and shampoos). Among the products, in recent years, the environmental health hazards caused by such compounds have received widespread attention in the fields of environmental science, public health, the media, and even the general public.

        On October 27, 2017, the preliminary list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization, bis(2-ethylhexyl) phthalate was included in the list of category 2B carcinogens.

        Phthalates hazard

        Studies have shown that phthalates play a similar role to female hormones in humans and animals, which can interfere with endocrine, reduce the amount of men's semen and sperm, reduce sperm motility, abnormal sperm morphology, and severely cause testicular cancer. It is the "culprit" causing male reproductive problems.

        Nail polish has the highest phthalate content in cosmetics, and many cosmetic fragrances also contain this substance. This substance in cosmetics will enter the body through the women's respiratory system and skin. If it is used too much, it will increase the chance of women suffering from breast cancer and will harm the reproductive system of the baby boy they will have in the future.
