DHEP stands for di-2-ethylhexyl phthalate, a chemical commonly used in plastics and industrial products. Synonyms for DHEP include DEHP, bis(2-ethylhexyl) phthalate, diethylhexyl phthalate, and 1,2-benzenedicarboxylic acid bis(2-ethylhexyl) ester. While these chemicals have similar properties, they may have different effects on human health and the environment. DHEP was added to the Candidate List of substances of very high concern (SVHCs) under the European Union's REACH regulation due to its endocrine-disrupting properties. As a result, many companies are seeking alternatives to DHEP to reduce their impact on the environment and protect public health.
