Attributed physical-property, hazard, environmental and use annotations.

  • Environmental Bioconcentration: An estimated BCF of 18 was calculated for flumioxazin(SRC), using an experimental log Kow of 2.55(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 column leaching studies and the short aerobic soil half-life, the potential for flumioxazin to leach in field agricultural soil is low(1). In soils that have been treated with flumioxazin, it is generally not found below 3 inches in depth(2). Volatilization losses from soil surfaces are negligible(1). Flumioxazin degrades rapidly in soil water via hydrolysis with half-lives of 3.4 to 5.1 days at pH 5.0, 21.4-24.6 hours at pH 7.0, and 14.6-22.0 minutes at pH 9.0(1); therefore, aqueous hydrolysis in moist soils will be an important fate process(SRC). Microbial degradation in soil is also an important fate process(1); the half-life for aerobic soil metabolism is 11.9 to 17.5 days, with an average of 14.7 days(1,2). The photolysis half-life on soil is 3.2 to 8.4 days (average 5.8 days)(2). The rapid soil dissipation rate indicates flumioxazin is not persistent in soil(1). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 13000(SRC), determined from a structure estimation method(2), indicates that flumioxazin is expected to adsorb to suspended solids and sediment(SRC). The hydrolytic degradation half-life of flumioxazin in soil water is 3.4 to 5.1 days at pH 5.0, 21.4-24.6 hours at pH 7.0, and 14.6-22.0 minutes at pH 9.0(3); therefore, hydrolysis will be the major degradation process in water(SRC). An anaerobic aquatic metabolism half-life of 0.2 days has been reported(4). The photolysis half-life in water at pH 5 is 1 day(4). Volatilization from water surfaces is expected to be slow(5) based upon an estimated Henry's Law constant of 6.28X10-7 atm-cu m/mole(SRC), derived from its vapor pressure, 2.41X10-6 mm Hg(6), and water solubility, 1.79 mg/l(4). Using this estimated Henry's Law constant and an estimation method(5), volatilization half-lives for a model river and model lake are 1,765 hours and 809 days, respectively(SRC). According to a classification scheme(7), an estimated BCF of 18(SRC), from a log Kow of 2.55(4) suggests the potential for bioconcentration in aquatic organisms is low(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), flumioxazin, which has a vapor pressure of 2.41X10-6 mm Hg at 25 °C (2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase flumioxazin 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 6.8 hours(SRC), calculated from its rate constant of 5.68X10-11 cu cm/molecule-sec at 25 °C(SRC) (that was derived using a structure estimation method(3). Particulate-phase flumioxazin may be removed from the air by wet and dry deposition(SRC). Source: Hazardous Substances Data Bank (HSDB)

How CAS 103361-09-7 is used on this site

CAS 103361-09-7 is the Chemical Abstracts Service identifier used to pin this page to a specific substance. In the current dataset, 1 EU annex record shares this identifier, which helps you cross-check whether the same substance appears under one regulatory context or several.

Use this page when a supplier specification, SDS or raw-material dossier gives you CAS 103361-09-7 and you need to see every linked Annex II–VI record in one place. The entry cards above are the quickest route to concentration limits, warnings, annex placement and product-type conditions.

Frequently asked questions

A substance identified by CAS 103361-09-7 may appear in multiple EU cosmetic regulation annexes when it is subject to different conditions in different contexts. For example, a substance might be restricted under Annex III with specific conditions, and the same CAS might also appear in Annex IV as an approved colorant under separate entry conditions. Each entry must be reviewed individually.

Cross-reference the CAS number against your raw material specification sheets and CoA documents. When a CAS appears in Annex II, verify absence. When it appears in Annex III, verify that concentration limits and product type conditions are met in your formulation. All annex entries sharing this CAS number are listed above.

A CAS number is assigned by the Chemical Abstracts Service (USA) and is globally recognised. An EC number is a European Commission identifier from inventories such as EINECS, ELINCS or the NLP list. Both identifiers may appear in EU cosmetic annex entries. Some substances have both, some have only one, and some older entries may have neither.

The INCI Checker accepts ingredient names, CAS numbers and EC numbers. Check this CAS number directly, then verify the result against supplier specification sheets and every linked annex condition.
