Diethyl phthalate

Catalog	ACM84662
CAS	84-66-2
Structure
Description	Diethyl phthalate appears as a clear, colorless liquid without significant odor. More dense than water and insoluble in water. Hence sinks in water. Primary hazard is to the environment. Spread to the environment should be immediately stopped. Easily penetrates soil, contaminates groundwater and nearby waterways. Flash point 325°F. Severely irritates eyes and mildly irritates skin. Used in the manufacture of perfumes, plastics, mosquito repellents and many other products.;Liquid;COLOURLESS OILY LIQUID.;Colorless to water-white, oily liquid with a very slight, aromatic odor.;Colorless to water-white, oily liquid with a very slight, aromatic odor.

Application	Diethyl phthalate serves multiple purposes across various industries due to its versatility as a plasticizer and solvent. Its primary role is to enhance the flexibility of plastics, making it valuable in the production of cellulose resin products and plastic film coatings for tablets and granules. As a solvent, it is widely used in the formulation of varnishes, dopes, and as an alcohol denaturant. Additionally, in the cosmetics industry, diethyl phthalate functions as a perfume fixative, ensuring scent longevity at low concentrations. Its ability to mix with various resins and solvents makes it a key component in manufacturing processes despite its high volatility, which sometimes limits its application. Furthermore, diethyl phthalate is utilized in the creation of insect repellents, deodorants, and emollients, highlighting its broad utility beyond the realm of plastics.
