Diethyl Phthalate (DEP) is a colourless and odourless liquid organic compound used in a variety of industrial applications. DEP is a phthalate ester of diethyl alcohol and phthalic acid, with a chemical formula of C12H14O4. It has a molecular weight of 222.23 g/mol and a boiling point of 349 °C (660.2 °F).

DEP is a non-flammable, low volatility, low toxicity chemical that is widely used in the manufacture of plastics, polyvinyl chloride (PVC) films, adhesives, paints, and inks. It acts as a plasticizer, improving the flexibility and softness of products. It is also used as a fragrance ingredient in many cosmetics and personal care products, including perfumes, deodorants, and soaps.

DEP is a good solvent, allowing it to dissolve and disperse a wide range of organic and inorganic compounds, making it a useful additive in many chemical processes. It is also used as a lubricant, lubricating parts in machinery and equipment that are exposed to high temperatures.

DEP is a potential environmental and health hazard if it is not handled properly. It can enter the environment through air, water, and soil, where it can accumulate in plants and animals and enter the food chain. It may also be released into the environment through industrial wastewater. Long-term exposure to DEP has been linked to a variety of health issues, including cancer, reproductive problems, and endocrine disruption.

DEP is a regulated substance in many countries and its use is strictly controlled. It is important to store it in a secure location, away from direct sunlight, and to dispose of it properly, according to local regulations.
