  • 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

  • Toxicity Summary: IDENTIFICATION AND USE: 2,2'-Dihydroxy-4-methoxybenzophenone (dioxybenzone) is a solid, which is used as a benzophenone sunscreen agent. Many sunscreens contain UVA-absorbing avobenzone or a benzophenone (such as dioxybenzone, oxybenzone, or sulisobenzone), in addition to UVB-absorbing chemical ingredients (some of which also contribute to UVA protection). HUMAN STUDIES: There are no human toxicity studies available. Although it has been suggested that benzophenone derivatives may protect against photosensitivity reactions to photosensitizing drugs (e.g., chlordiazepoxide, chlorpromazine, demeclocycline, hydrochlorothiazide, nalidixic acid, nystatin, sulfisoxazole), most clinicians agree that these sunscreens provide, at most, only limited protection for patients who are sensitive to these drugs. ANIMAL STUDIES: Dioxybenzone was nonmutagenic when assayed directly and was weakly mutagenic with metabolic activation in Salmonella strain TA1537. Dioxybenzone was not mutagenic in vivo in the mouse micronucleus test. In mice, signs of toxicity including decreased activity, piloerection, and exophthalmus were observed at doses of 166-5000 mg/kg.

  • Environmental Bioconcentration: An estimated BCF of 40 was calculated in fish for 2,2'-dihydroxy-4-methoxybenzophenone(SRC), using an estimated log Kow of 3.82(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1300(SRC), determined from a structure estimation method(2), indicates that 2,2'-dihydroxy-4-methoxybenzophenone is expected to have low mobility in soil(SRC). Volatilization of 2,2'-dihydroxy-4-methoxybenzophenone from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.0X10-9 atm-cu m/mole(SRC), developed using a fragment constant estimation method(2). 2,2'-Dihydroxy-4-methoxybenzophenone is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.0X10-7 mm Hg at 25 °C(SRC), determined from a fragment constant method(2). Utilizing the CO2 Evolution Test, 0% CO2 Evolution was reached in 28 days(3) 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), an estimated Koc value of 1300(SRC), determined from a structure estimation method(2), indicates that 2,2'-dihydroxy-4-methoxybenzophenone is 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 2.0X10-9 atm-cu m/mole(SRC), developed using a fragment constant estimation method(2). According to a classification scheme(4), an estimated BCF of 40(SRC), from an estimated log Kow of 3.82(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). Utilizing the CO2 Evolution Test, 0% CO2 Evolution was reached in 28 days(5) 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), 2,2'-dihydroxy-4-methoxybenzophenone, which has an estimated vapor pressure of 2.0X10-7 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase 2,2'-dihydroxy-4-methoxybenzophenone 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 2 hours(SRC), calculated from its rate constant of 2.0X10-10 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(2). Particulate-phase 2,2'-dihydroxy-4-methoxybenzophenone may be removed from the air by wet and dry deposition(SRC). UV light absorbing substances, such as 2,2'-dihydroxy-4-methoxybenzophenone, accepted as a means of protecting skin against UV radiation damage, absorb UV light in the range of 285-400 nm(2) suggesting that this compound may be susceptible to direct photolysis by sunlight(SRC).
