Diisobutyl Phthalate

Diisobutyl phthalate (DiBP) is a phthalate ester that is the diester obtained by the formal condensation of the carboxy groups of phthalic acid with two molecules of isobutanol Diisobutyl phthalate (DiBP) is considered a specialty plasticizer that is too volatile for use in polyvinyl chloride (PVC). It is often combined with other phthalates. It has good heat and light stability and has been used as a plasticizer for nitrocellulose (lowest cost plasticizer for cellulose nitrate), cellulose ether, and polyacrylate and polyacetate dispersions. It is used in nail polish, cosmetics, lubricants, floor carpets, tapestry, clothing treatments, rubber dentistry settings, as a fuel stabilizer, in leather varnishes and lacquers, as a concrete additive, as an adjusting agent for lead chromate paint pigments, explosive material, lacquer manufacturing, and methyl methacrylate applications. Diisobutyl phthalate (DiBP) is also used in printing inks for paper and packaging. Because DiBP has similar properties as dibutyl phthalate (DBP), it can be used as a substitute for DBP.
