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.

However, it is essential to note that the effectiveness of biodegradable masterbatch hinges on proper disposal practices. While these materials are designed to decompose in specific conditions, such as industrial composting facilities, they may not degrade efficiently in standard landfill conditions. Therefore, public awareness and infrastructure improvements for waste management are critical components of ensuring the success of biodegradable masterbatch as a sustainable alternative.
