  • NFPA Health Rating: 0 - Materials that, under emergency conditions, would offer no hazard beyond that of ordinary combustible materials. Source: Hazardous Substances Data Bank (HSDB)
  • NFPA Fire Rating: 1 - Materials that must be preheated before ignition can occur. Materials require considerable preheating, under all ambient temperature conditions, before ignition and combustion can occur. Source: Hazardous Substances Data Bank (HSDB)
  • NFPA Instability Rating: 0 - Materials that in themselves are normally stable, even under fire conditions. Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: An estimated BCF of 1.4 was calculated in fish for bis(2-methoxyethyl) phthalate(SRC), using an estimated log Kow of 1.11(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 a classification scheme(1), an estimated Koc value of 38(SRC), determined from a water solubility of 8500 mg/L(2) and a regression-derived equation(3), indicates that bis(2-methoxyethyl) phthalate is expected to have very high mobility in soil(SRC). Volatilization of bis(2-methoxyethyl) phthalate from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.8X10-13 atm-cu m/mole(SRC), using a fragment constant estimation method(4). Bis(2-methoxyethyl) phthalate is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.3X10-4 mm Hg(SRC), determined from a fragment constant method(5). Bis(2-methoxyethyl) phthalate was biodegraded 19.3% using an enzyme extracted from N. erythropolis(6), suggesting that bis(2-methoxyethyl) phthalate is susceptible to biodegradation(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 38(SRC), determined from a water solubility of 8500 mg/L(2}and a regression-derived equation(3), indicates that bis(2-methoxyethyl) phthalate 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 2.8X10-13 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(5), an estimated BCF of 1.4(SRC), from an estimated log Kow(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Hydrolysis is not expected to be an important process(SRC) based on estimated hydrolysis half-lives of 1.3 years and 49 days at pHs 7 and 8, respectively(8). Bis(2-methoxyethyl) phthalate was biodegraded 19.3% using an enzyme extracted from Nocardia erythropolis(9), suggesting that bis(2-methoxyethyl) phthalate may be susceptible to biodegradation(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), bis(2-methoxyethyl) phthalate, which has an estimated vapor pressure of 2.3X10-4 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase bis(2-methoxyethyl) phthalate 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 20 hours(SRC), calculated from its rate constant of 1.9X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Bis(2-methoxyethyl) phthalate does contain chromophores that absorb at wavelengths >290 nm(4) and therefore may be susceptible to direct photolysis by sunlight(SRC).

How CAS 117-82-8 is used on this site

CAS 117-82-8 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 117-82-8 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 117-82-8 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.
