  • First Aid: EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.; SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.; INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) shou Source: CAMEO Chemicals

  • NFPA Fire Rating: 2 - Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. Materials would not under normal conditions form hazardous atmospheres with air, but under high ambient temperatures or under moderate heating could release vapor in sufficient quantities to produce hazardous atmospheres with air.

  • Environmental Bioconcentration: An estimated BCF of 3 was calculated in fish for diethylene glycol monomethyl ether(SRC), using an estimated log Kow of -1.18 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 1(SRC), determined from a structure estimation method(2), indicates that diethylene glycol monomethyl ether is expected to have very high mobility in soil(SRC). Volatilization of diethylene glycol monomethyl ether from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.6X10-11 atm-cu m/mole(SRC), using a fragment constant estimation method(2). Diethylene glycol monomethyl ether is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.25 mm Hg at 25 °C(3). Aqueous screening test data suggest that biodegradation may be an important removal mechanism of diethylene glycol monomethyl ether in soil: theoretical BOD losses of 0, 21 and 66% when incubated at 20 °C for 5, 10 and 20 days, respectively, were reported(4). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1(SRC), determined from a structure estimation method(2), indicates that diethylene glycol monomethyl ether 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 1.6X10-11 atm-cu m/mole(SRC), developed using a fragment constant estimation method(2). Diethylene glycol monomethyl ether is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3). According to a classification scheme(4), an estimated BCF of 3(SRC), from an estimated log Kow of -1.18(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Aqueous screening test data suggest that biodegradation may be an important removal mechanism of diethylene glycol monomethyl ether: theoretical BOD losses of 0, 21 and 66% when incubated at 20 °C for 5, 10 and 20 days, respectively, were reported(5). 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), diethylene glycol monomethyl ether, which has a vapor pressure of 0.25 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase diethylene glycol monomethyl ether 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 13 hours(SRC), calculated from its rate constant of 2.6X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Alcohols and ethers do not contain chromophores that absorb at wavelengths >290 nm(4) and, therefore, diethylene glycol monomethyl ether is not expected to be susceptible to direct photolysis by sunlight(SRC).

How CAS 111-77-3 is used on this site

CAS 111-77-3 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 111-77-3 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 111-77-3 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.
