Plastics have become an integral part of modern life, influencing countless aspects of our daily activities, from packaging and construction materials to automotive components and consumer electronics. However, the plastic products we use are rarely made from pure polymer resins. Instead, they are often enhanced with various additives that improve their performance, durability, and aesthetics. This article explores the key additives commonly used in plastics and their functions.


Manufacturers must adhere to stringent regulations and standards set by health authorities to ensure the safety and efficacy of their products. This includes quality control measures at every stage of production, from sourcing ingredients to packaging the final product. Furthermore, advancements in technology allow manufacturers to optimize their processes, making it possible to produce more effective Vitamin C formulations with better absorption rates and stability.


The handbook emphasizes the importance of accurate chemical analysis methods to determine the composition of plastic and polymer additives. Given the complex nature of these materials, traditional analytical techniques such as gravimetry and titration often fall short. Instead, advanced methods like gas chromatography-mass spectrometry (GC-MS), high-performance liquid chromatography (HPLC), and Fourier-transform infrared spectroscopy (FTIR) have become standard tools in the analytical laboratory. These techniques allow for the precise identification and quantification of both organic and inorganic additives in diverse plastic matrices.


Conclusion


The year 2020 was a year when the global pharmaceutical industry was profoundly affected by the epidemic. It was also a year when China’s API industry withstood the test of fluctuations in the international market.  According to the preliminary statistics of China Chamber of Commerce for Medical Insurance, in 2020, China’s API exports reached us $35.7 billion, another record high, with a year-on-year growth of about 6%.

Lisinopril, an angiotensin-converting enzyme (ACE) inhibitor, is another important API. It is used to treat high blood pressure and heart failure. This medication works by relaxing blood vessels, which improves blood flow and lowers blood pressure. The significance of lisinopril in managing cardiovascular health showcases how APIs can directly influence public health outcomes.
