Di-n-butyl phthalate (CAS 84-74-2)

Di-n-butyl phthalate (DBP) is a used plasticizer in various polymer-based products, particularly in polyvinyl chloride (PVC) plastics. As a plasticizer, Di-n-butyl phthalate improves the flexibility, durability, and workability of the plastic. It helps make the plastic more malleable and less prone to brittleness, making it suitable for applications in construction materials, coatings, adhesives, and vinyl flooring. It is also employed as a solvent for dyes, pigments, resins, and other organic compounds. Additionally, it can be used as an additive in lubricants, inks, and paints to improve their flow and compatibility, as well as in the production of cellulose-based materials, such as cellulose acetate and cellulose nitrate. Di-n-butyl phthalate acts as an agonist of the nuclear hormone receptors, such as the estrogen receptor, androgen receptor, and thyroid receptor. It also interferes with the metabolism of steroid hormones, leading to altered hormone levels. Di-n-butyl phthalate is a potential endocrine disruptor and has been linked to reproductive and developmental toxicity. In vitro studies have been conducted to evaluate the effects of DBDi-n-butyl phthalateP on cell proliferation, apoptosis, and gene expression. Scientific research studies have reported anti-oxidant and anti-inflammatory activities of Di-n-butyl phthalate. In addition, it may act to have an inhibitory effect on the enzyme cytochrome P450.
