  • Environmental Bioconcentration: An estimated BCF of 3.2 was calculated for tetraethyl pyrophosphate(SRC), using an estimated log Kow of 0.45(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC), provided the compound is not altered physically or chemically once released into the environment. Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 2.2(SRC), determined from a water solubility of 1.00X10+6 mg/L(2) and a regression-derived equation(3), indicates that tetraethyl pyrophosphate is expected to have very high mobility in soil(SRC). Volatilization of tetraethyl pyrophosphate from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.2X10-10 atm-cu m/mole(SRC) derived from its vapor pressure, 2.60X10-4 mm Hg at 25 °C(2), and water solubility(2). Tetraethyl pyrophosphate is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(2). Biodegradation data for this substance were not located in the literature.

  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 2.2(SRC), determined from a water solubility of 1.00X10+6 mg/L(2) and a regression-derived equation(3), indicates that tetraethyl pyrophosphate is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 2.2X10-10 atm-cu m/mole(SRC), derived from its vapor pressure, 2.60X10-4 mm Hg at 25 °C(2), and water solubility(2). Using this Henry's Law constant and an estimation method(3). According to a classification scheme(4), an estimated BCF of 3.2(SRC), from an estimated log Kow(5) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Biodegradation data for this substance were not located in the literature. 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), tetraethyl pyrophosphate, which has a vapor pressure of 2.60X10-4 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase tetraethyl pyrophosphate 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 5.0 hours(SRC), calculated from its rate constant of 7.7X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3).

Questions this page answers

This official record identifies the substance as prohibited for cosmetic use in the stated market scope. Do not rely on a formulation containing this identity until the cited source, effective date and exact substance match have been verified.

A prohibition entry may contain no separate condition text because the regulatory outcome is the prohibition itself. No list match is not permission; Gulf/SFDA product, claim, notification and technical requirements still apply.

The record cites SFDA prohibited list, page 28, row 8, source version live-snapshot-2026-08-30. Open the official source.

No. CAS helps resolve identity, but jurisdictions can classify the same substance differently and can apply different product scopes, limits, warnings and transition dates.
