Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name ANISALDEHYDE.

That is a statement about this inventory, not about the law: no imported rule is not evidence that a substance is permitted. A rule may exist under a different name, under a CAS or EC number this glossary entry does not carry, or in a dataset not yet imported.

  • Toxicity Summary: IDENTIFICATION AND USE: p-Anisaldehyde is oily liquid. It is used in perfumery and toilet soaps. It is also used in organic syntheses. p-Anisaldehyde is also an intermediate in many industrial processes. HUMAN STUDIES: When tested at 10% in petrolatum, it produced no irritation after a 48 hr closed-patch test on human subjects. A maximization test was carried out on 25 volunteers. The material was tested at a concentration of 10% in petrolatum and produced no sensitization reactions. p-Anisaldehyde was positive for sister chromatid exchange in human lymph oocytes but not Chinese Hamster Ovary (CHO) cells in vitro. ANIMAL STUDIES: In a combined oral repeated-dose/reproductive/developmental toxicity screening test in rats, decreased body weights, decreased platelets and hypertrophy of hepatocytes were noted at 100 mg/kg/day. In reproduction studies, it showed significantly reduced fertility index, number of pups/litter, delivery index and number of live pups at 500 mg/kg/day. It was not mutagenic in bacteria but it was mutagenic in mouse lymphoma cells in vitro. Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: An estimated BCF of 6.7 was calculated in fish for p-anisaldehyde(SRC), using a log Kow of 1.76(1) and a regression-derived equation(1). According to a classification scheme(2), 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 53(SRC), determined from a log Kow of 1.76(2) and a regression-derived equation(3), indicates that p-anisaldehyde is expected to high mobility in soil(SRC). Volatilization of p-anisaldehyde from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.4X10-5 atm-cu m/mole(SRC) derived from its vapor pressure, 3.29X10-2 mm Hg(4), and water solubility, 4.29X10+3 mg/L(5). p-Anisaldehyde has a vapor pressure of 3.29X10-2 mm Hg at 25 °C(4) and exists as a liquid under environmental conditions; therefore, p-anisaldehyde may volatilize from dry soil. A 99% of theoretical BOD using activated sludge in the Japanese MITI test(6) suggests that biodegradation is an important environmental fate process in soil(SRC).

  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 53(SRC), determined from a log Kow of 1.76(2) and a regression-derived equation(3), indicates that p-anisaldehyde is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(4) based upon an estimated Henry's Law constant of 1.4X10-5 atm-cu m/mole(SRC) derived from its vapor pressure, 3.29X10-2 mm Hg(5), and water solubility, 4.29X10+3 mg/L(6). Using this Henry's Law constant and an estimation method(4), volatilization half-lives for a model river and model lake are 20 days and 230 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 6.7(SRC), from its log Kow(2) and a regression-derived equation(3), suggests the potential for bioconcentration in aquatic organisms is low(SRC). A 99% of theoretical BOD using activated sludge in the Japanese MITI test(7) suggests that biodegradation is an important environmental fate process in water(SRC). 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), p-anisaldehyde, which has a vapor pressure of 3.29X10-2 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase p-anisaldehyde 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 15 hours(SRC), calculated from its rate constant of 2.5X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). p-Anisaldehyde absorbs UV light at wavelengths >290 nm(4) and, therefore, may be susceptible to direct photolysis by sunlight(SRC).
