diisooctyl phthalate

diisooctyl phthalate (diop or dioctyl isophthalate) is a synthetic phthalate ester widely used as a plasticizer to increase the flexibility, transparency, and durability of plastics, particularly in polyvinyl chloride (pvc) products. it is a colorless, oily liquid with low volatility and is primarily used in industrial and commercial applications.

extensively used as a plasticizer in pvc-based materials such as cables, flooring, hoses, artificial leather, and coatings.
found in products like adhesives, paints, sealants, and rubber compounds.
used in medical devices, although being phased out in favor of safer alternatives due to potential toxicity concerns.
exposure occurs mainly through inhalation, ingestion, or dermal contact, especially in occupational settings.

studies suggest potential for endocrine disruption, particularly affecting reproductive and hormonal systems in animals.
bioaccumulation is low, but it may persist in soil and sediment, leading to long-term environmental contamination.
regulatory agencies in some countries have restricted or banned its use in toys, childcare articles, and certain packaging.
ongoing evaluation for safer plasticizer alternatives is encouraging its replacement in many consumer products.
