- Cosmetic Ingredient Review Conclusion: Based on available data, the CIR Expert Panel concluded that...Triethylene Glycol Dimethacrylate is safe as used in nail enhancement products when skin contact is avoided. Products containing these ingredients should be accompanied with directions to avoid skin contact, because of the sensitizing potential of Methacrylates. Source: Cosmetic Ingredient Review (CIR)
- Cosmetic Ingredient Review Finding(s): Safe for use in cosmetics, with qualifications Source: Cosmetic Ingredient Review (CIR)
- Environmental Bioconcentration: An estimated BCF value of 16 was calculated for triethylene glycol dimethacrylate(SRC), using an experimental log Kow of 1.88(1) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 250(SRC), determined from an experimental log Kow(2) and a recommended regression-derived equation(3), indicates that triethylene glycol dimethacrylate will have moderate mobility in soil(SRC). Volatilization of triethylene glycol dimethacrylate should not be important from moist soil surfaces(SRC) given an estimated Henry's Law constant of 1.7X10-12 atm-cu m/mole(SRC), using a recommended regression equation(4). Volatilization from dry soil surfaces(SRC) is not expected based on an estimated vapor pressure of 9.4X10-4 mm Hg(SRC), determined from a fragment constant method(5). Insufficient data are available to determine the rate or importance of biodegradation of triethylene glycol methacrylate in soil(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 250(SRC), determined from an experimental log Kow(2) and a recommended regression-derived equation(1), indicates that triethylene glycol dimethacrylate may adsorb to suspended solids and sediment in the water(SRC). Triethylene glycol dimethacrylate will be non-volatile from water surfaces(1,SRC) based on an estimated Henry's Law constant of 1.7X10-12 atm-cu m/mole(SRC), developed using a fragment constant estimation method(3). According to a classification scheme(4), an estimated BCF value of 16(1,SRC), from an experimental log Kow(2), suggests that bioconcentration in aquatic organisms is low(SRC). Base catalyzed half-lives for triethylene glcycol dimethacrylate have been estimated(SRC), through a structure estimation method(5), to be 1.6 years and 16 years at pHs of 8 and 7, respectively(5,SRC). Insufficient data are available to determine the rate or importance of biodegradation of triethylene glycol methacrylate 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), triethylene glycol dimethacrylate, which has an estimated vapor pressure of 9.4X10-4 mm Hg at 25 °C(2,SRC), would exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase triethylene glycol dimethacrylate 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 about 5.7 hours(3,SRC). Vapor-phase triethylene glycol dimethacrylate is also degraded in the atmosphere by reaction with atmospheric ozone(SRC); the half-life for this reaction in air is estimated to be about 12 hours(3,SRC). Particulate-phase triethylene glycol dimethacrylate may be physically removed from the air by wet and dry deposition(SRC). Source: Hazardous Substances Data Bank (HSDB)
