Dibutyl Phthalate

Dibutyl Phthalate (DBP) is a chemical compound that belongs to the supply class of Chemicals in the supply group Chemicals And Chemical Products. It is commonly used as a plasticizer, which means it is added to plastics to increase their flexibility, durability, and transparency.

Here are some key characteristics and uses of Dibutyl Phthalate:

1. Chemical Formula: C16H22O4
2. Molecular Weight: 278.34 g/mol
3. Appearance: DBP is a clear, colorless liquid with a slight odor.
4. Solubility: It is soluble in most organic solvents but has limited solubility in water.
5. Stability: DBP is stable under normal conditions but may degrade when exposed to heat, light, or air.
6. Toxicity: It is considered to have low acute toxicity, but prolonged exposure or ingestion may have harmful effects on human health.
7. Regulatory Status: Dibutyl Phthalate is regulated in many countries due to its potential health and environmental risks. It is restricted or banned in certain applications, such as children's toys and food packaging.

Uses of Dibutyl Phthalate include:

1. Plasticizer: DBP is primarily used as a plasticizer in various applications, including PVC (polyvinyl chloride) products like vinyl flooring, cables, and automotive parts. It improves the flexibility and workability of the plastic.

2. Adhesives and Sealants: DBP is also used in adhesives and sealants to enhance their performance and durability.

3. Personal Care Products: It can be found in some cosmetics, such as nail polishes, as a solvent and plasticizer.

4. Industrial Applications: Dibutyl Phthalate is used in industrial processes, such as printing inks, paints, and coatings, to improve their flow properties and adhesion.

It is important to note that due to its potential health and environmental concerns, there has been a shift towards using alternative plasticizers with lower toxicity profiles.
