About Dioctyl Phthalate (DOP)

Dioctyl Phthalate (DOP), also known as bis(2-ethylhexyl) phthalate (DEHP), is an organic compound with the chemical formula C₂₄H₃₈O₄. It is a colourless, viscous liquid commonly used as a plasticiser to enhance the flexibility and durability of polymers, particularly polyvinyl chloride (PVC). Industrially, DOP is produced by the esterification of phthalic anhydride with 2-ethylhexanol, resulting in a compound that is insoluble in water but soluble in oils and organic solvents. Its versatility and cost-effectiveness have made it one of the most widely utilised plasticisers in various applications.

Dioctyl Phthalate Uses

Plasticiser for PVC Products

DOP is predominantly used as a plasticiser in the production of flexible PVC products. By incorporating DOP, manufacturers can produce items such as flooring, carpet tiles, canvas tarps, swimming pool liners, notebook covers, traffic cones, toys, vinyl gloves, garden hoses, weather stripping, flea collars, and shoes. The addition of DOP imparts flexibility, durability, and resistance to environmental factors, making these products suitable for diverse applications. :contentReference[oaicite:0]{index=0}

Medical Devices

In the medical field, DOP is utilised as a plasticiser in the manufacture of medical and sanitary products, such as blood bags and dialysis equipment. Notably, DOP helps to prolong the life of stored blood by stabilising the membranes of red blood cells, enabling blood product storage in PVC blood bags for several weeks. :contentReference[oaicite:1]{index=1}

Coatings and Adhesives

DOP is employed as a plasticiser and dye carrier in the production of films, wires, cables, and adhesives. Its inclusion enhances the flexibility and workability of these materials, improving their performance in various applications. :contentReference[oaicite:2]{index=2}

Lubricants and Hydraulic Fluids

Beyond its role as a plasticiser, DOP is used in the formulation of lubricants and hydraulic fluids. Its chemical properties make it suitable for use as a dielectric fluid in capacitors and as a solvent in glowsticks. :contentReference[oaicite:3]{index=3}
