Carbendazim

Carbendazim is a member of the class of benzimidazoles that is 2-aminobenzimidazole in which the primary amino group is substituted by a methoxycarbonyl group. A fungicide, carbendazim controls Ascomycetes, Fungi Imperfecti, and Basidiomycetes on a wide variety of crops, including bananas, cereals, cotton, fruits, grapes, mushrooms, ornamentals, peanuts, sugarbeet, soybeans, tobacco, and vegetables. It has a role as a metabolite, an antinematodal drug, a microtubule-destabilising agent and an antifungal agrochemical. It is a member of benzimidazoles, a carbamate ester, a benzimidazole fungicide and a benzimidazolylcarbamate fungicide. It is functionally related to a 2-aminobenzimidazole. ChEBI

  • Health Effects: Carbendazim is a suspected endocrine disruptor. It is also a developmental toxin. Animals exposed to carbendazim in the womb to have serious deformities such as lack of eyes and hydrocephalus (water on the brain). Carbendazim can disrupt the development of sperm and damage testicular development in adult rats. Source: Toxin and Toxin Target Database (T3DB)
  • Toxicity Summary: IDENTIFICATION AND USE: Carbendazim is a white powder. it is a systemic leaf and soil fungicide, absorbed through the roots and green tissues. HUMAN EXPOSURE AND TOXICITY: Six human chromosomes were investigated in pairs (1 and 8, 11 and 18, and X and 17). Abnormalities were classified as chromosome loss (including centromeric positive micronuclei), chromosome gain, non-disjunction, or polyploidy. ANIMAL STUDIES: Previous studies indicate that carbendazim may interfere with mitosis and thus may disrupt or inhibit microtubule function resulting in apoptosis. Carbendazim even at low dose exhibited toxicity, affected the liver and also caused specific changes in hematological and biochemical parameters in the rat. Male rats (6 per dose level) were gavaged with 200, 3400 and 5000 mg/kg 5 days/wk for 2 wk. Two out of the 6 rats died at the dose level of 3400 mg/kg per day. At all dose levels, gross and microscopic evidence of adverse effects on the testes and reduction or absence of sperm in the epididymides was seen. The testes were small and discolored, with tubular degeneration and evidence of aspermatogenesis. At the dose level of 3400 mg/kg per day, there were also morphological ch Source: Hazardous Substances Data Bank (HSDB)
  • Toxicity Summary: Carbendazim targets beta tubulin in actively dividing cells. It binds to microtubules, interfering with cell functions, such as meiosis and intracellular transportation (A15332). Source: Toxin and Toxin Target Database (T3DB)
  • Environmental Bioconcentration: BCFs of <1.5-3.5 and 0.6-1.1 were measured using carp (Cyprinus carpio) exposed to 2 and 20 ug/L, respectively, carbendazim over a 6-week period(1). Carbendazim was not bioconcentrated in perch (Perca fluviatilis) and carp exposed to food pellets containing a mixture of 13 pesticides(2). According to a classification scheme(3), these BCF values suggest bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), Koc values of 122.3-2805(2-3), indicate that carbendazim is expected to have high mobility in some soils with decreasing mobility as the amount of clay and organic carbon content increases, pH will have a lesser effect on mobility. Volatilization of carbendazim from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.5X10-12 atm-cu m/mole(SRC), using a fragment constant estimation method(4). Carbendazim is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 7.5X10-10 mm Hg at 25 °C(5). Measured soil biodegradation rates of 45% in 21 days and 45% in 14 days suggest that carbendazim is expected to biodegrade slowly under normal environmental conditions(6). However, biodegradation rates of 100% in 5 days and 97% in 9 days suggest that biodegradation of carbendazim will be enhanced in pretreated soils(6). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Carbendazim is absorbed through the roots and green tissues of plants, with translocation acropetally. Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), Koc values of 122.3-2805(2-3), indicate that carbendazim is 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 1.5X10-12 atm-cu m/mole(SRC), developed using a fragment constant estimation method(5). Measured hydrolysis half-lives for carbendazim at 22 °C were >350 days at pH 5-7 and 124 days at pH 9(6). According to a classification scheme(7), BCFs of <1.5-3.5 measured in carp(8), suggest bioconcentration in aquatic organisms is low(SRC). A 0% of Theoretical BOD using activated sludge in the Japanese MITI test(8) suggests that biodegradation is not an important environmental fate process in water(SRC).

  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), carbendazim, which has a vapor pressure of 7.5X10-10 mm Hg at 25 °C(2), is expected to exist solely in the particulate phase in the ambient atmosphere. Particulate-phase carbendazim may be removed from the air by wet and dry deposition(SRC). Source: Hazardous Substances Data Bank (HSDB)

How CAS 10605-21-7 is used on this site

CAS 10605-21-7 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 10605-21-7 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 10605-21-7 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.
