| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), a Koc range of 2,514 to 3,561(2) indicates that triphenyl phosphate is expected to have slight mobility in soil(SRC). Volatilization of triphenyl phosphate from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.3X10-6 atm-cu m/mole(SRC), based upon its vapor pressure, 2.00X10-6 mm Hg(3), and water solubility, 1.9 mg/L(4). However, adsorption to soil is expected to attenuate volatilization(SRC). Triphenyl phosphate is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(3). Mineralization half-lives of 37 and 32 days under aerobic and anaerobic conditions, respectively, using a loamy sand(2) suggest that biodegradation may be an important environmental fate process in soil(SRC).AQUATIC FATE: Based on a classification scheme(1), a Koc range of 2,514 to 3,561(2) indicates that triphenyl phosphate is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 3.3X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 2.00X10-6 mm Hg(4), and water solubility, 1.9 mg/L(5). Estimated volatilization half-lives for a model river and model lake are 20 and 152 days, respectively. However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 400 days if adsorption is considered(6). According to a classification scheme(7), bioconcentration factors ranging from 132(8) to 573(9) suggest that bioconcentration in aquatic organisms is high(SRC). Biodegradation half-lives of 2-4 days in river die-away tests(10) suggest that biodegradation may be an important environmental fate process in water(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), triphenyl phosphate, which has a vapor pressure of 2.00X10-6 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase triphenyl phosphate is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 12 hours(SRC), calculated from its rate constant of 1.1X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase triphenyl phosphate may be removed from the air by wet and dry deposition(SRC). Triphenyl phosphate does not absorb light at wavelengths >290 nm(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC). |
| Lebensmitteluntersuchungswerte | Triphenyl phosphate has been detected in a composite grain product sample (flours, breads, and cereals)however, this food sample may have been contaminated during analysis through laboratory reagents that contain triphenyl phosphate(1). Triphenyl phosphate was detected in 8 out of 230 ready to eat foods in the US at an average concentration of 0.2803 ug/g(2). The compound was tested for but not detected in 228 fresh potato samples sold at 34 farm markets in Alberta, Canada(3). |

| Toxizitätsübersicht | Safe in the present practices of use and concentration. Ingredient, concentration, and use information are available in documents discoverable at https://cir-reports.cir-safety.orgIDENTIFICATION AND USE: Triphenyl phosphate (TPP) is a solid. It is used as fire-retarding agent, and a plasticizer for cellulose acetate and nitrocellulose. Triphenyl phosphate also has been found as one component of lubricating oil and hydraulic fluids. HUMAN STUDIES: It causes a delayed peripheral neuritis involving motor neurons, resulting in a flaccid paralysis, particularly of the distal muscles. No sensory disturbances. Potential symptoms of overexposure are minor changes in blood enzymes. In workers engaged in the manufacture of TPP there was some inhibition of plasma cholinesterase but no correlation of this effect with degree of exposure or with minor gastrointestinal or neuromuscular symptoms. A case of TPP allergy from spectacle frames was reported. TPP increased both 17beta-estradiol (E2) and testosterone concentrations in human H295R cells in vitro. In addition, transcription of four major steroidogenic genes was up-regulated and that of two sulfotransferase genes was down-regulated. Increase of TPP concentration in house dust was associated with a 10% increase in prolactin and a 19% decrease in sperm concentration in exposed men. ANIMAL STUDIES: Topical application of TPP to rats and mice caused no skin irritation. Because cholinesterase was not inhibited after topical application of TPP, it was concluded that percutaneous absorption was limited. TPP caused generalized delayed illness and paralysis in cats and primates. Administration of 0.2 g/kg of TPP s.c. caused paralysis in cats and fatal doses ranged between 0.3-1.0 g/kg. In mice choline esterase activity was reduced after doses of 10 to 500 mg/kg bw to 87.1 to 30.4% of control. No cholinergic or other symptoms were reported. TPP acted in vitro as antagonist of estrogen receptor inhibiting binding of E2 to estrogen receptor. Zebrafish retinoic acid receptor (RAR) may be involved in mediating TPP-induced developmental toxicity. Perinatal exposure to TPP exacerbates the development of obesity in male and female rats. TPP mutagenicity was negative at doses of 0, 100, 333, 1000, 3333, and 10,000 ug/plate in four Salmonella typhimurium strains (TA98, TA100, TA1535, and TA1537) in the presence and absence of metabolic activation. In vitro TPP was found to cause significant direct inhibition of monocyte antigen presentation at non-cytotoxic concentrations as low as 1 umol/L. ECOTOXICITY STUDIES: Vertebral damage and spinal curvature were observed in rainbow trout exposed to TPP for 96 hr. The growth of green algae was completely inhibited at concentrations of 1 mg/L or more but stimulated at lower concentrations (0.1 and 0.05 mg/L). TPP could increase the thyroid hormone concentrations in the early life stages of zebrafish by disrupting the central regulation and hormone synthesis pathways. |
| Average Daily Intake | The average daily intake (AVDI) of triphenyl phosphate in 8 population groups in 1982-1984 was determined according to the FDA's monitoring program for chemical contaminants in the U.S. food supply (Total Diet Study or Market Basket Study). In 6-11 month old infants, the AVDI was 0.3 ng/kg-body weight-per day. In 2 yr old toddlers, the AVDI was 4.4 ng/kg-body weight-per day. In 14-16 year old females, the AVDI was 1.6 ng/kg-body weight-per day. In 14-16 year old males, the AVDI was 1.2 ng/kg-body weight-per day. In 25-30 year old females, the AVDI was 0.8 ng/kg-body weight-per day. In 25-30 year old males, the AVDI was 1.6 ng/kg-body weight-per day. In 60-65 year old females, the AVDI was 0.5 ng/kg-body weight-per day. In 60-65 year old males, the AVDI was 0.5 ng/kg-body weight-per day(1). |

At concentration of 3 ppm or 5 ppm, all fish died within 5 hr and 1 hr, respectively. /Histological changes similar to mice and rats TPP poisoning/ congestion, degeneration, and hemorrhage from smaller blood vessels, pronounced mostly in liver, kidney, and brain./AQUATIC SPECIES/ Vertebral damage and spinal curvature were observed in rainbow trout exposed to triphenyl phosphate for 96 hr./AQUATIC SPECIES/ ...The growth of green algae was completely inhibited at concentrations of 1 mg/L or more but stimulated at lower concentrations (0.1 and 0.05 mg/L). The nitrogenase activity, measured by the acetylene reduction technique, of a cyanobacterium (blue-green alga: Anabaena flosaquae) was affected by TPP. Additions of 0.1, 1.0, and 5.0 mg/L reduced the nitrogenase activity to 84, 77, and 68% of the control value, respectively./AQUATIC SPECIES/ The toxicities of five phosphate ester compounds - Fyrquel GT, Kronitex 200, Phosflex 31P, Pydraul 50E and Santicizer 148-were evaluated in acute toxicity tests with rainbow trout (Salmo gairdneri), fathead minnows (Pimephales promelas), channel catfish (Ictalurus punctatus) and bluegills (Lepomis macrochirus) and in 90 day partial life-cycle tests with fathead minnows. Nominal exposure concentrations were 0, 0.06, 0.12, 0.25, 0.5 and 1.0 mg/L in the partial life-cycle tests with Fyrquel GT, Kronitex 200, Phosflex 31P and Pydraul 50E, and 0, 0.05, 0.09, 0.19, 0.38 and 0.75 mg/L in the test with Santicizer 148. The 96 hr LC50 values for rainbow trout, fathead minnows, channel catfish and bluegills exposed to the five phosphate esters ranged from <0.3 to >72 mg/L. The LC50 values may be directly related to the percentage of triphenyl phosphate contained in each of the compounds. The phosphate esters generally showed similar chronic toxicities to fathead minnows, and adverse toxic effects occurred at nominal exposure concentrations of 0.38 to 1.0 mg/L. Comparison of available environmental concentration data for phosphate esters with the effect concentrations obtained for fish in the present study indicated that phosphate ester compounds may not now pose a threat to fish populations. /SRP: Formulated products/For more Ecotoxicity Excerpts (Complete) data for Triphenyl phosphate (6 total), please visit the HSDB record page. |

Anwendungen & Verwendung
Verwenden
Triphenyl phosphate is known as a product with manifold fields of applications regarding its qualities in particular as a flame retardant. One primary use is as a flame retardant in phenolic- and phenylene oxide-based resins for the manufacture of electrical and automobile components, for auto upholstery, and as a nonflammable plasticizer in cellulose acetate for photographic films. It has also been used to impregnate roofing paper. Triphenyl phosphate occurs as a plasticizer in various lacquers and varnishes (O'Neil, 2006), and as a component of lubricating oil and hydraulic fluids (ACGIH, 2012).
Herstellung & Synthese
synthetische
Triphenyl phosphate is prepared by reacting phosphorus pentoxide and phenol (Budavari, 2001), or by reacting phosphorus oxychloride and phenol (Snyder, 1990). On a larger scale phosphorus oxychloride and phenol are reacted in an esterification tank with heating. The HCL formed is trapped and condensed, while the crude triphenyl phosphate runs into a large tank where it is purified.
