diisoksyyaineeseen

Diisoksyyaineeseen, also known as diisooctyl phthalate (DIOP), is a chemical compound. It belongs to the class of phthalate esters. Phthalates are esters of phthalic acid, a dicarboxylic acid. DIOP is characterized by its two branched eight-carbon (isooctyl) alcohol chains attached to the phthalate core. Its chemical formula is C24H38O4.

DIOP is typically a colorless, oily liquid with a low volatility. It is not soluble in water but is soluble in many organic solvents. Its primary industrial application has been as a plasticizer, a substance added to plastics to increase their flexibility, transparency, and workability. Specifically, it has been used in the production of polyvinyl chloride (PVC) and other polymers.

Due to its chemical structure and properties, DIOP has found uses in various products, including some types of flooring, cables, and films. However, like other phthalates, its use has been subject to scrutiny and regulatory review due to potential health and environmental concerns. Research has investigated the potential for phthalates to leach from products and their possible endocrine-disrupting effects. Consequently, the use of certain phthalates, including DIOP in some applications, has been restricted or phased out in various regions in favor of alternative plasticizers.
