Rapport (övrigt vetenskapligt/konstnärligt)abstract
- A literature and database review was conducted with the aim of identifying substitute substances forregulated plasticizers that are of relevance within Sweden. Based on this survey substitute substanceswere prioritized and suggested for national screening studies.Information sources used were lists/databases, scientific literature, reports, interviews with businessorganizations (within or connected to the plasticizers industry), manufacturers, importers and users.Plasticizers that are already regulated or on their way to be have been listed, as well as a list of possiblesubstitute substances for these regulated plasticizers.The first list of potential candidates for screening constituted 152 substances. To be able to prioritizebetween identified plasticizers, a multicriteria model was developed based on usage, presence ofsubstance on different lists, and classification. In total 40 substances were selected for further evaluation.As volume is a critical parameter for exposure, 15 substances were thereafter selected. This prioritizationwas crosschecked with the information obtained from interviews with selected representatives from theindustry, which added one more substance to the priority list. Since the Swedish Environmental ProtectionAgency requested that substances previously included in various screenings should be excluded, the finallist consisted of eleven selected plasticizers.From the developed multicriteria model, the following plasticizers were identified: Dipropylene glycoldibenzoate (DGD); Alkanes, C14-17, chloro; Dioctyl adipate (DOA); Benzyl 3-isobutyryloxy-1-isopropyl-2,2-dimethylpropyl phthalate; 2,2,4-trimethyl-1,3 pentanediol di-isobutyrate (TXIB); Diisononyl adipate(DINA); Diethylene glycol dibenzoate (DEGD; DEGDB); Hexanedioic acid, polymer with 1,4-butanedioland 2,2-dimethyl-1,3-propanediol, isononyl ester (Palamoll 654; Palamoll 656); Epoxidised soybean oil(ESBO); (second DINP line) 1,2-Benzenedicarboxylic acid, di-C8-10-branched alkyl esters, C9-rich(DINP); and Tris-2-ethylhexyl trimellitate (TOTM).These plasticizers are suggested to be prioritized in future screening studies.
