Phthalates, also known as phthalates, abbreviation PAE, are the collective name for esters formed from phthalic acid. When used as a plasticizer, it generally refers to esters of phthalic acid with 4 to 15 carbon alcohols. Among them, dioctyl phthalate is the most important species.

Introduction Properties: Generally a very low viscous liquid. Preparation method: esterification of phthalic anhydride and alcohol in the presence of acid (such as **) catalyst. Role: Phthalates (Phthalates) is a group of chemical compounds, mainly used for PVC materials, so that PVC from hard plastic to flexible plastic, play the role of plasticizer.

It is commonly used in hundreds of applications such as toys, food packaging materials, medical blood bags and hoses, vinyl flooring and wallpapers, detergents, lubricating oils, personal care products (such as nail polish, hair sprays, soaps and shampoos) In the product. From the current situation, people pay most attention to phthalates in children's products. Professor Cheng said that in 1999, the European Union formally took a decision on the content of phthalates in toys (such as baby pacifiers) and other children's products used by children under 3 years of age under the age of 3 in EU member states. Strict restrictions. Experts have found that soft plastic toys and children's products containing phthalates may be put in children's imports. If they are left for a long time, the amount of phthalates released will exceed the safe level, which will endanger Children's liver and kidneys can also cause precocious puberty in children. The European Union will ban or restrict the use of six phthalates in children's toys and products. The European Parliament voted to ban the use of three plasticizers in toys and limit the use of the other three plasticizers in toys. European plasticizer manufacturers are particularly concerned and believe that the ban is too harsh and does not consider scientific risk assessments. Germany's latest research shows that there are chemicals that endanger health in many cosmetics, toys, and food packaging. According to a recent press release issued by the German Research Association, studies have shown that the reduction in the number of sperm in the world's men over the past few decades may be related to the use of phthalates, chemicals that are widely used as softeners in the light industry.
