di2ethylhexylphthalate

Di(2-ethylhexyl) phthalate, often abbreviated as DEHP, is a synthetic organic compound. It belongs to the class of phthalates and is widely used as a plasticizer, a substance added to plastics to increase their flexibility, transparency, durability, and longevity. DEHP is one of the most common phthalates used commercially.

Its primary application is in the production of polyvinyl chloride (PVC), making it a significant component in a variety of flexible PVC products. These include items like flooring, medical devices such as blood bags and tubing, electrical cable insulation, and some types of packaging. DEHP is valued for its ability to impart softness and flexibility to otherwise rigid PVC.

The widespread use of DEHP has led to its detection in the environment and in human tissues. Concerns have been raised regarding its potential health effects, particularly its classification as an endocrine disruptor. Regulatory bodies in various countries have established limits for DEHP content in certain products, especially those intended for children or for medical use. Research continues to explore its toxicological profile and environmental fate.
