Pentaerythritol

Pentaerythritol is a tetrol that is neopentane in which one of the methyl hydrogens of all four methyl groups are replaced by hydroxy groups. It is a chemical intermediate used in the production of explosives, plastics, paints, appliances, and cosmetics. It has a role as a laxative and a flame retardant. It is a primary alcohol and a tetrol. It derives from a hydride of a neopentane. — ChEBI

  • Toxicity Summary: Pentaerythritol is a stable solid and the production volume was ca. 25,000 tonnes/year in 1996 and 1997 in Japan. The chemical is used as intermediate for alkyd resin, rosin ester, explosive and lubricants. No consumer use is reported... Predicted No Effect Concentration (PNEC) of the chemical was determined using a Daphnia magna 48 h immobility data (600 mg/L). The assessment factor of 1000 used to an acute toxicity data to determine PNEC, ... , because only one acute toxicity data is available among algae, cladocera and fishes. Thus, PNEC of the chemical is determined as 0.6 mg/l, tentatively. Thus, PEC / PNEC is 0.0072. Effects of the chemical on aquatic ecosystems are of low concern at present. Pentaerythritol was not mutagenic in bacterial and chromosomal aberration tests in vitro. The chemical is not considered as an irritant to the skin and the eyes, nor as a sensitizer. In a combined repeat dose and reproductive/developmental toxicity screening test, both male and female rats showed only soft feces and diarrhea. The chemical did not show any toxicity to parents and offspring. The no observed effect levels were 100 mg/kg/day for repeated dose toxicity and 1000 mg/kg/day for Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: Values for BCF of 0.3-0.6 and 0.2-2.1 were calculated in fish for pentaerythritol(SRC), using carp (Cyprinus carpio) which were exposed 10 and 1 ppm pentaerythritol, respectively, over an 6-week period(1). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1.5(SRC), determined from a log Kow of -1.69(2) and a regression-derived equation(3), indicates that pentaerythritol is expected to have very high mobility in soil(SRC). Volatilization of pentaerythritol from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 4.1X10-10 atm-cu m/mole(SRC), using a fragment constant estimation method(4). Pentaerythritol is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.5X10-8 mm Hg at 25 °C(SRC), determined from a fragment constant method(5). Utilizing the Japanese MITI test, 13.2% of the Theoretical BOD was reached in 25 days(6) indicating that biodegradation is not an important environmental fate process in soil(SRC). However, aerobic biodegradation test results for pentaerythritol do show varying results(7). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1.5(SRC), determined from a log Kow of -1.69(2) and a regression-derived equation(3), indicates that pentaerythritol is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(4) based upon an estimated Henry's Law constant of 4.1X10-10 atm-cu m/mole(SRC), developed using a fragment constant estimation method(5). According to a classification scheme(6), a BCF range of 0.3-2.1 using carp (Cyprinus carpio)(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Utilizing the Japanese MITI test, 13.2% of the Theoretical BOD was reached in 25 days(7) indicating that biodegradation is not an important environmental fate process in water(SRC). However, aerobic biodegradation test results for pentaerythritol do show varying results(8). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), pentaerythritol, which has an estimated vapor pressure of 2.5X10-8 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase pentaerythritol 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 26 hrs(SRC), calculated from its rate constant of 1.48X10-11 cu cm/molecule-sec at 25 °C(3). Particulate-phase pentaerythritol may be removed from the air by wet or dry deposition(SRC). Pentaerythritol does not contain chromophores that absorb at wavelengths >290 nm(4) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).
