Flame Retardants

Tris(tribromoneopentyl) phosphate
19186-97-1

Where is it Commonly Found?

Tris(tribromoneopentyl) phosphate (TTBP) is used as an additive flame retardant in thermoplastics, styrene and polyurethane (NILU 2008), polypropylene, high-impact polystyrene (HIPS), ABS plastic, extruded polystyrene, alloys, and adhesives. Combined with antimony trioxide, it can be used in polypropylene molding applications for UL94 V-2 flammability ratings and will pass a California 701 burn test (Unitex 2004).

HEALTH EFFECT SUMMARY

Little toxicity data is available on TTBP (NILU 2008). However, TTBP was assessed under the Australian National Industrial Chemicals Notification and Assessment Scheme (NICNAS 1999) and was found to have “moderate potential for bioaccumulation” and low toxicity or tested negative on all tests listed, based on tests performed according to OECD guidelines.

The related brominated aliphatic phosphate ester tris(2,3-dibromopropyl) phosphate (TBPP) have been found to be genotoxic. However, TTBP lacks a structural feature needed for the metabolic transformation of TBPP to genotoxic metabolites, suggesting that TTBP would not have the same genotoxic effects. The assessment also concluded that TTBP would have a low environmental hazard, based on lack of toxicity in tests on certain aquatic species and low mobility in water.
