  • Health Effects: Acute exposure to cholinesterase inhibitors can cause a cholinergic crisis characterized by severe nausea/vomiting, salivation, sweating, bradycardia, hypotension, collapse, and convulsions. Increasing muscle weakness is a possibility and may result in death if respiratory muscles are involved. Accumulation of ACh at motor nerves causes overstimulation of nicotinic expression at the neuromuscular junction. When this occurs symptoms such as muscle weakness, fatigue, muscle cramps, fasciculation, and paralysis can be seen. When there is an accumulation of ACh at autonomic ganglia this causes overstimulation of nicotinic expression in the sympathetic system. Symptoms associated with this are hypertension, and hypoglycemia. Overstimulation of nicotinic acetylcholine receptors in the central nervous system, due to accumulation of ACh, results in anxiety, headache, convulsions, ataxia, depression of respiration and circulation, tremor, general weakness, and potentially coma. When there is expression of muscarinic overstimulation due to excess acetylcholine at muscarinic acetylcholine receptors symptoms of visual disturbances, tightness in chest, wheezing due to bronchoconstriction, incre Source: Toxin and Toxin Target Database (T3DB)
  • Toxicity Summary: IDENTIFICATION AND USE: Benzophenone (BZP) comes in the form of orthorhombic prisms, monoclinic prisms, and white crystals. It has a characteristic sweet geranium or rose-like odor. BZP is used as a photoinitiator, a fragrance enhancer, an ultraviolet stabilizer, and, occasionally, as a flavor ingredient; it is also used in the manufacture of insecticides, agricultural chemicals, pharmaceuticals (antihistamines), hypnotics, paints, lacquers and cosmetics; and is an additive for plastics, coatings, and adhesives. Not registered for current use as a pesticide in the U.S., but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses. HUMAN EXPOSURE AND TOXICITY: There is limited information on the toxic effects of BZP in humans published. It showed little activity in the hormone-responsive reporter assay tested in various cell lines. ANIMAL STUDIES: BZP showed no estrogenic activity, however, after irradiating an aqueous solution of BZP with UV or sunlight, it can be converted into ring-hydroxylated derivatives (3-hydroxy BP (BP-3OH) and 4-hydroxyBP (BP-4OH)) that have estrogenic activity. BP-4OH was more Source: Hazardous Substances Data Bank (HSDB)
  • Toxicity Summary: Benzophenone is a cholinesterase or acetylcholinesterase (AChE) inhibitor. A cholinesterase inhibitor (or 'anticholinesterase') suppresses the action of acetylcholinesterase. Because of its essential function, chemicals that interfere with the action of acetylcholinesterase are potent neurotoxins, causing excessive salivation and eye-watering in low doses, followed by muscle spasms and ultimately death. Nerve gases and many substances used in insecticides have been shown to act by binding a serine in the active site of acetylcholine esterase, inhibiting the enzyme completely. Acetylcholine esterase breaks down the neurotransmitter acetylcholine, which is released at nerve and muscle junctions, in order to allow the muscle or organ to relax. The result of acetylcholine esterase inhibition is that acetylcholine builds up and continues to act so that any nerve impulses are continually transmitted and muscle contractions do not stop. Among the most common acetylcholinesterase inhibitors are phosphorus-based compounds, which are designed to bind to the active site of the enzyme. The structural requirements are a phosphorus atom bearing two lipophilic groups, a leaving group (such as a h Source: Toxin and Toxin Target Database (T3DB)
  • Environmental Bioconcentration: BCF values of 3.4-9.2 were measured using carp (Cyprinus carpio) which were exposed to benzophenone concentrations of 0.3 ppm over an 6-week period(1). According to a classification scheme(2), this BCF range 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), Koc values of 413(2) and 517(3) indicate that benzophenone is expected to have moderate to low mobility in soil(SRC). Volatilization of benzophenone from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.9X10-6 atm-cu m/mole(SRC), based upon its vapor pressure, 1.93X10-3 mm Hg(4), and water solubility, 137 mg/L(5). Benzophenone is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(4). Utilizing the Japanese MITI test, 0% of the Theoretical BOD was reached in 2 weeks(6) indicating that biodegradation is not an important environmental fate process in soil(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), Koc values of 430(2) and 517(3) indicate that benzophenone 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 1.9X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 1.93X10-3 mm Hg(5), and water solubility, 137 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 15 and 110 days, respectively(SRC). According to a classification scheme(7), a BCF range of 3.4-9.2(8) suggests that bioconcentration in aquatic organisms is low(SRC). Utilizing the Japanese MITI test, 0% of the Theoretical BOD was reached in 2 weeks(8) indicating that biodegradation is not 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), benzophenone, which has a vapor pressure of 1.93X10-3 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase benzophenone 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 3 days(SRC), calculated from its rate constant of 3.6X10-12 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Benzophenone absorbs UV light at wavelengths >290 nm(4) and, therefore, may be susceptible to direct photolysis by sunlight(SRC). Source: Hazardous Substances Data Bank (HSDB)

How CAS 119-61-9 is used on this site

CAS 119-61-9 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 119-61-9 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 119-61-9 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.
