Dioctyl Phthalate

Dioctyl phthalate (DOP) is a clear, colourless liquid which is slightly more dense than water with a slight but characteristic odour. It is miscible with most organic solvents but not soluble in water.

It has several advantages over some other plasticizers in that it is more economical; it provides the desired changes to physical and mechanical properties without causing changes to the chemical structure of the polymer; it jellifies quickly; in lacquer applications it serves to eliminate cracks, increase resistance and provide a smooth surface.

Applications of Dioctyl Phthalate

Dioctyl phthalate is a phthalate ester which is used in the manufacture of a wide range of plastics and coating products. It is used as a plasticizer in PVC paste and pulp mixtures and as an additive in many other processes.

It can be found in many end products including PVC soles for shoes and slippers, synthetic leather, waterproof membranes, paints, varnishes, floor coverings, door mats and hoses.

It is also used in the calendaring process of paper finishing, to produce PVC granules, as a hydraulic or dielectric fluid in capacitors, in toxicology studies and in risk assessment studies on food contamination which occurs via migration of phthalates into foodstuffs from food-contact materials (FCM).

Storage and Handling

Dioctyl phthalate should be stored in tightly-closed containers in a cool, dry, well-ventilated place.

This material should be handled in accordance with good industry safety and hygiene practices. Relevant engineering controls should be implemented. The product may cause skin irritation if contact is repeated or prolonged, as well as severe eye irritation. Risks from inhalation of vapour are minimal at room temperature but may cause irritation at higher temperatures. Personal protective equipment including approved safety glasses, impervious clothing and gloves must be worn, and respirators should be worn where deemed necessary by risk assessments for the task being carried out.
