84-74-2
Product name: Dibutyl Phthalate
English alias: DBP; n-Dibutyl phthalate; Butyl phthalate
CAS: 84-74-2
Molecular formula: C16H22O4
Appearance: Colorless or light yellow transparent oily liquid
Package: 200 kg/drum, 1000 kg/IBC tank
Dibutyl Phthalate (DBP) is a low molecular weight phthalate plasticizer produced by the esterification of phthalic anhydride with n-butanol. It is characterized by its strong solvating power, high plasticizing efficiency, and good gelation properties with PVC resins. DBP offers excellent softening effects and fast processing characteristics but has higher volatility and lower permanence compared to higher molecular weight phthalates like DINP or DIDP. Its relatively low viscosity makes it useful in certain specialty applications.

1. Dibutyl Phthalate used as a plasticizer in PVC products, especially where high solvating power and fast processing are required, such as in PVC pastes (plastisols) and synthetic leather.
2. Employed as a plasticizer for nitrocellulose lacquers to improve flexibility and durability.
3. It used as a solvent and fixative in perfumes and fragrances to slow down the evaporation of scent notes.
4. Dibutyl Phthalate applied as a dielectric fluid in capacitors.
5. Used as a component in adhesive formulations and sealing compounds.
6. Employed as a softening agent in certain elastomers.
7. Historically used in cellulose acetate and other resins (use now highly restricted in many applications).
DBP is subject to significant global regulatory restrictions due to health concerns, including classification as a reproductive toxicant and endocrine disruptor. Its use is heavily regulated in toys, childcare articles, cosmetics, and food-contact materials under regulations such as REACH, CPSIA, and others. Avoid inhalation of mists and prolonged skin contact. Use appropriate personal protective equipment (PPE) including gloves and safety glasses. Ensure good ventilation. It is essential to consult and comply with all applicable local, national, and international regulations before use.
Store in a cool, dry, well-ventilated area away from direct sunlight, heat, and open flames. Keep containers tightly closed to prevent moisture absorption and evaporation. Recommended storage temperature: 10-40 °C. Store away from strong oxidizing agents, strong acids, and bases.
DBP is typically supplied in 200 kg steel or HDPE drums and 1000 kg IBC containers. Classified as an environmentally hazardous substance and often subject to specific hazard classifications (e.g., Repr. 2 according to CLP); verify exact shipping classification based on the latest regulations.
