Once an API is developed, it undergoes rigorous testing to ensure its safety and efficacy. This includes preclinical studies, often conducted in vitro (in test tubes) and in vivo (in live organisms), followed by multiple phases of clinical trials with human subjects. Each phase aims to assess different aspects, such as dosage safety, effectiveness, and adverse effects. This stringency is crucial, as even small changes in the API's chemistry can significantly affect the drug's performance and safety profile.

Plasticizers are classified into two main categories primary and secondary. Primary plasticizers, such as dioctyl phthalate (DOP) and diisononyl phthalate (DINP), are typically used in large quantities and can significantly alter the properties of the base polymer. Secondary plasticizers, on the other hand, are added in smaller amounts and serve to enhance the performance of primary plasticizers or modify specific characteristics of the material. The choice of plasticizer depends on various factors, including cost, desired properties, and regulatory considerations.
