Phthalate Esters
Clear liquid; [Hawley] Oily viscous liquid; [CHEMINFO]
Used as plasticizer for polyvinyl chloride in calendered film, coated fabrics, building wire jackets, wire and cable extrusion, and other applications; [HSDB]
An irritant; [Hawley] Oral LD50 (rat) = 64,000 mg/kg; [ChemIDplus] A skin and eye irritant; May cause liver injury; [ICSC] Like dioctyl phthalate, it may cause CNS depression and mild liver toxicity after ingestion of large amounts; [HSDB] A mild skin and eye irritant; "Di-"isodecyl" phthalate is a complex mixture containing mainly C10-branched isomers, with a mean formula, C28-H46-O4 and a mean molecular weight of 446.68. There are two di-"isodecyl" phthalate products (DIDP), with two different CAS Nos. (26761-40-0 and 68515-49-1), which contain a number of components. The main chemical structures or chain structures present in DIDP, include trimethylheptyl, dimethyloctyl, methylnonyl and n-decyl." [CHEMINFO] May cause irritation; [MSDSonline] See "PHTHALATE ESTERS." See "1,2-Benzenedicarboxylic acid, di-C9-11-branched alkyl esters, C10-rich."
