  • Health Effects: Exposure to high levels of cyanide for a short time harms the brain and heart and can even cause coma, seizures, apnea, cardiac arrest and death. Chronic inhalation of cyanide causes breathing difficulties, chest pain, vomiting, blood changes, headaches, and enlargement of the thyroid gland. Skin contact with cyanide salts can irritate and produce sores. (L96, L97) Source: Toxin and Toxin Target Database (T3DB)

  • NFPA Fire Rating: 1 - Materials that must be preheated before ignition can occur. Materials require considerable preheating, under all ambient temperature conditions, before ignition and combustion can occur. Source: Hazardous Substances Data Bank (HSDB)
  • NFPA Instability Rating: 0 - Materials that in themselves are normally stable, even under fire conditions. Source: Hazardous Substances Data Bank (HSDB)
  • Toxicity Summary: Organic nitriles decompose into cyanide ions both in vivo and in vitro. Consequently the primary mechanism of toxicity for organic nitriles is their production of toxic cyanide ions or hydrogen cyanide. Cyanide is an inhibitor of cytochrome c oxidase in the fourth complex of the electron transport chain (found in the membrane of the mitochondria of eukaryotic cells). It complexes with the ferric iron atom in this enzyme. The binding of cyanide to this cytochrome prevents transport of electrons from cytochrome c oxidase to oxygen. As a result, the electron transport chain is disrupted and the cell can no longer aerobically produce ATP for energy. Tissues that mainly depend on aerobic respiration, such as the central nervous system and the heart, are particularly affected. Cyanide is also known produce some of its toxic effects by binding to catalase, glutathione peroxidase, methemoglobin, hydroxocobalamin, phosphatase, tyrosinase, ascorbic acid oxidase, xanthine oxidase, succinic dehydrogenase, and Cu/Zn superoxide dismutase. Cyanide binds to the ferric ion of methemoglobin to form inactive cyanmethemoglobin. (L97) Source: Toxin and Toxin Target Database (T3DB)
  • Environmental Bioconcentration: An estimated BCF of 3 was calculated for succinonitrile(SRC), using a log Kow of -0.99(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). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 28(SRC), determined from a structure estimation method(2), indicates that succinonitrile is expected to have very high mobility in soil(SRC). Volatilization of succinonitrile from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 6.5X10-9 atm-cu m/mole(SRC), derived from its vapor pressure, 0.00778 mm Hg(3), and water solubility, 126.9 g/L(4). Succinonitrile is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.00778 mm Hg(3). In studies with activated sludge, biodegradation of 1.5-3.8% was observed after 6-24 hours(5). These studies suggest that succinonitrile may have been toxic to the microorganisms, since a high concentration of succinonitrile was used(5). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 28(SRC), determined from a structure estimation method(2), indicates that succinonitrile 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 6.5X10-9 atm-cu m/mole(SRC), derived from its vapor pressure, 0.00778 mm Hg(4) and water solubility, 126.9 g/L(5). According to a classification scheme(6), an estimated BCF of 3(SRC), from its log Kow of -0.99(7) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions(9). In studies with activated sludge, biodegradation of 1.5-3.8% was observed after 6-24 hours(10). These studies suggest that succinonitrile may have been toxic to the microorganisms, since a high concentration of succinonitrile was used(10). 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), succinonitrile, which has a vapor pressure of 0.00778 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. The reaction of vapor-phase succinonitrile with photochemically-produced hydroxyl radicals is not expected to be an important environmental fate based on the estimated half-life for this reaction in air of 380 days, calculated from its rate constant of 4.3X10-14 cu cm/molecule-sec at 25 deg (SRC) that was derived using a structure estimation method(3). Succinonitrile is not expected to be susceptible to direct photolysis by sunlight, since it does not contain functional groups that are expected to absorb light with wavelengths >290 nm(SRC).

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 16, row 2, 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.
