The odor was attributed to wood pallets that had been treated with a mold control chemical called "tribromophenol" or TBP.
Miller says that CHEP also guarantees its pallets have not been treated with TBP (tribromophenol) a wood fungicide that Johnson & Johnson blamed for a recall of Tylenol, Motrin and other medicines last fall after consumers complained of feeling sick from an unusual odor.
The company announced its its range of brominated flame retardants include HBCD (Hexabromocyclodecane) with all grades of CD-75P and SP75 DE-83R (Decabromodiphenyl oxide); Firemaster 2100R (Decabromodiphenyl ethane); PH-73FF (2,4,6 Tribromophenol); BA-59P (Tetrabromobisphenol A); BC-52 and BC-58 (carbonate oligomers); PDBS-80, Firemaster PBS-64HW and Firemaster CP-44HF with grades of polybromostyrene PHT-4 (tetrabromophthalic anhydride) and derivatives; Firemaster 500/600 series and PE-68 and DP-45.
We focused on four low-cost biocides as one component, three of which are already employed in wood preservation (Nicholas and Schultz 1995) [boric acid/borates; the quat didecyldimethylammonium chloride (DDAC); and Cu(II)], and one low-cost organic that had been previously examined as a possible preservative and once apparently sold in South America, tribromophenol (TBP).

of Indianapolis has announced a worldwide price increase of 10% for all brominated flame retardants and derivatives, including: dibromostyrene--Great Lakes' PBS and PDBS; tetrabromoplithalic anhydride-Great Lakes' PHT-4 and PHT4DIOL; hexabromocyclOdOdeCaneGreat Lakes' CD-75 series; tetrabromobisphenol A-Great Lakes' BA-59P; octabromodiphenyl oxide-Great Lakes' DE-79; and tribromophenol additives-Great Lakes' P11-73.
These samples include several novel, sulfidogenic pure cultures which degrade alkanes, toluene, and tribromophenol. Additionally, we have sulfidogenic consortia that re-mineralize benzene, naphthalene, 2-methylnaphthalene, and phenanthrene as a sole carbon source.
Tribromophenol (1 mL of 1000 [micro]g/mL) was added to each sample as an internal standard.
also announces that prices for PH-73FF tribromophenol flame retardant are increasing by [yen]30/kg in Japan and by US$0.25/kg in all other regions, effective September 15, where contracts allow.
Associations between PBDEs, 2,4,6 tribromophenol and thyroid hormone levels in human placental tissues [Abstract].
Hexabromocyclodecane (CD-75P) and tetrabromobisphenol A-bis allyl ester (BE-51) and tribromophenol allyl ether (PHE-65) recommended for expanded PS foam.
The company also has introduced a briquette form of tribromophenol, PH73-FF, which has much improved flow and anti-caking tendencies over standard tribromophenol.
