1、 What is plasticizer?

Plasticizer is a polymer chemical product material additive commonly used in industrial production, also known as plasticizer, which is phthalate ester. It is also used in food packaging, cosmetics, and medical equipment. In recent years, it has been exposed that many enterprises' products have been contaminated by plasticizers, including fruit juice drinks, tea drinks, jam, cans, Baijiu and other food products. At that time, plasticizer detection will become a focus 2. Application Fields of Plasticizers

1. Plasticizers are bulk industrial products widely used in various fields of the national economy, including plastics, rubber, adhesives, cellulose, resins, medical devices, cables, and thousands of other products 2. For example, the commonly used cling film is a PE (polyethylene) material without additives, but its viscosity is poor; Another widely used type is PVC (polyvinyl chloride) cling film, which contains a large amount of plasticizers to make PVC (polyvinyl chloride) material soft and increase viscosity, making it very suitable for packaging fresh food Another widely used product with plasticizers is children's toys made of PVC. The European Union has already specified that the content of plasticizers in plastic toys should be below 0.1%, but there is currently no clear regulation or restriction in Taiwan

4. For cosmetics such as perfume and nail polish frequently used by women, phthalates are used as fragrance fixatives to maintain the fragrance or make the nail polish film smoother

III. Harms of plasticizers

Food packaging materials directly come into contact with food and are closely related to food safety. According to data, plasticizers will cause harm to the reproductive system, immune system, and digestive system of the human body, such as damaging male reproductive ability, promoting female precocious puberty, and may cause gender imbalance in children. Long term consumption of plasticizers can also lead to liver cancer. Therefore, products or things that come into contact with people, such as plastics, food, beverages, soil, atmosphere, etc., may require testing for plasticizers 4. Analysis of plasticizer components

1. Phthalate esters (PAEs) are esterification derivatives of phthalate acid and are the most common plasticizers 2. Phthalate esters are widely used in daily life and industry, with di (2-ethylhexyl) phthalate (DEHP) as the largest group, accounting for three-quarters of plasticizer production, followed by dibutyl phthalate (DBP) Phthalate plasticizers are colorless liquids with a slight aromatic or odorless odor, with moderate viscosity, high stability, low volatility, low cost, and low water solubility. However, they are easily soluble in most organic solvents
