Phthalates, also known as phthalates, abbreviated PAE, are a general term for esters formed from phthalic acid. Phthalate is a class of chemicals that soften and is widely used as a plasticizer in toys, food packaging, vinyl flooring, wallpaper, detergents, nail polish, sprays, shampoos and body washes. Among hundreds of products. Studies have shown that phthalate can interfere with endocrine, reducing the number of male sperm, low exercise capacity, abnormal morphology, and serious death and testicular cancer, which is the "culprit" of male reproductive problems.

On December 14, 2005, the European Parliament and the Council promulgated the Phthalates Directive (2005/84/EC), which was later replaced by 552/2009/EC, and is the current REACH Regulation Annex 17, which requires children's toys. DEHP, DBP and BBP in children's care products are less than 1000ppm in plastic materials; DINP, DIDP and DNOP are less than 1000ppm in children's importable plastic materials. All of the above products may not be placed on the market if they do not meet the limit requirements.

Following 2005/84/EC, countries have enacted laws and regulations governing phthalates in toys. In 2007, California State issued AB 1108 to control ortho-benzene 6P in toys. No one can produce or sell the following products: DEHP, DBP, BBP with a concentration of more than 0.1% of children's toys or child care products; any containing DINP, DIDP, DNOP Children's toys or child care products that can be placed in the mouth for children under 3 years of age at concentrations greater than 0.1%. In 2008, the United States in the Consumer Product Safety Improvement Act CPSIA controlled toys in the phthalate 6P, which is stipulated in the law for 180 days (February 10, 2009), the following products will be considered illegal: any containing DEHP, DBP, BBP Children's toys or child care products with a concentration greater than 0.1%; any children's toys or child care products that contain more than 0.1% DINP, DIDP, DNOP and can be placed in the mouth.

China, GB 24613 -2009 "Determination of Hazardous Substances in Toy Coatings" requires that the concentration of phthalate DEHP, DBP and BBP in toy paints is less than 0.1%; the total concentration of DINP, DIDP, DNOP is not more than 0.1%.

Japan, Canada and other countries have also developed control requirements for phthalates in toys.
