  • 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.

  • Environmental Bioconcentration: An estimated BCF of 3 was calculated for glycidyl methacrylate(SRC), using an estimated log Kow of 0.81(1,SRC) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low. Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 10(SRC), determined from a structure estimation method(2), indicates that glycidyl methacrylate is expected to have very high mobility in soil(SRC). Volatilization of glycidyl methacrylate from moist soil surfaces is expected to occur slowly(SRC) given an estimated Henry's Law constant of 3.1X10-7 atm-cu m/mole(SRC), using a fragment constant estimation method(3). Glycidyl methacrylate is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 0.62 mm Hg(SRC), determined from a fragment constant method(4). Screening tests indicate that glycidyl methacrylate is readily biodegradable; it reached 93-94% of its theoretical BOD in 4 weeks using an activated sludge inoculum(5). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 10(SRC), determined from a structure estimation method(2), indicates that glycidyl methacrylate is not expected to adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces is expected to occur slowly(3) based upon an estimated Henry's Law constant of 3.1X10-7 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Volatilization half-lives for a model river and model lake are 140 days and 1000 days, respectively(SRC), using an estimation method(3). According to a classification scheme(5), an estimated BCF of 3(3), from an estimated log Kow of 0.81(6), suggests the potential for bioconcentration in aquatic organisms is low. A base-catalyzed second-order hydrolysis rate constant of 7X10-3 L/mole-sec(SRC) was estimated using a structure estimation method(7); this corresponds to half-lives of 31 yrs and 3 yrs at pH values of 7 and 8, respectively(7). The rate constant estimated for the epoxide does not include neutral hydrolysis rate constant. For some epoxides, the neutral rate constant is the dominant hydrolysis rate at environmental pHs.

  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), glycidyl methacrylate, which has an estimated vapor pressure of 0.62 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase glycidyl methacrylate 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 17 hours(SRC) from its estimated rate constant of 3.1X10-7 cu cm/molecule-sec at 25 °C(3). Because the structurally similar ethyl methacrylate does not absorb light in the environmental spectrum above 290 nm(4), direct photolysis of glycidyl methacrylate is not expected to occur(SRC).

How CAS 106-91-2 is used on this site

CAS 106-91-2 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 106-91-2 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 106-91-2 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.
