  • 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: (Tris(2-chloroethyl) phosphate is a Clear, transparent liquid. It is used primarily as an additive plasticizer and viscosity regulator with flame-retarding properties for polyurethane, polyesters, polyvinyl chloride and other polymers. HUMAN EXPOSURE AND TOXICITY: Tris(2-chloroethyl) phosphate did not consistently demonstrate detectable unscheduled DNA synthesis with and without metabolic activation and failed to show a dose-response relationship in human WI-38 cells. ANIMAL STUDIES: In repeat dose studies Tris(2-chloroethyl) phosphate caused adverse effects on the brain (hippocampal lesions in rats), liver and kidneys. Non-irritant to eyes, but conflicting reports in the literature on skin irritation, has not been tested for sensitization potential. Not teratogenic. It adversely affects the fertility of male rats and mice. In vitro mutagenicity test results were inconsistent and an in vivo micronucleus test gave equivocal results. Tris(2-chloroethyl) phosphate causes benign and malignant tumors at various organ sites in rats and mice. A very high oral dose caused some inhibition of plasma cholinesterase and brain neuropathy target esterase, but did not caus Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: A BCF of 2.2 was determined for tris(2-chloroethyl) phosphate using killifish (Oryzias latipes) exposed to the chemical in static water for 72 hr(1). A BCF of 0.9 was obtained for goldfish (Carassius auratus) under identical conditions(1). BCFs of 1.1 and 1.3 were determined using killifish exposed to 12.7 ppm of tris(2-chloroethyl) phosphate for 5 days and 2.3 ppm for 11 days, respectively, in a continuous flow water system(2). BCFs of <1.2-5.1 and 0.6-0.8 were reported in carp (Cyprinus carpio) which were exposed to tris(2-chloroethyl) phosphate at 0.1 and 1 ppm, respectively, over a 6-week period(3). According to a classification scheme(4), these BCF values suggest 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 390(SRC), determined from a structure estimation method(2), indicates that tris(2-chloroethyl) phosphate is expected to have moderate mobility in soil(SRC). Volatilization of tris(2-chloroethyl) phosphate from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.3X10-6 atm-cu m/mole(SRC), based upon its vapor pressure, 6.13X10-2 mm Hg(3), and water solubility, 7000 mg/L(4). Tris(2-chloroethyl) phosphate is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(3). A 4% of theoretical BOD using activated sludge in the Japanese MITI test(5) suggests that biodegradation is not an important environmental fate process in soil(SRC).

  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 390(SRC), determined from a structure estimation method(2), indicates that tris(2-chloroethyl) phosphate is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 3.3X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 6.13X10-2 mm Hg(4), and water solubility, 7000 mg/L(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 19 and 140 days, respectively(SRC). Tris(2-chloroethyl) phosphate may undergo hydrolysis in the environment based on an estimated hydrolysis half-life of 20 days at pH 5 to 9(2). According to a classification scheme(6), measured BCF values of 0.6-5.1 in fish(7-9), suggest bioconcentration in aquatic organisms is low(SRC). A 4% of theoretical BOD using activated sludge in the Japanese MITI test(7) suggests 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), tris(2-chloroethyl) phosphate, which has a vapor pressure of 6.13X10-2 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase tris(2-chloroethyl) phosphate 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 16 hours(SRC), calculated from its rate constant of 2.2X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Tris(2-chloroethyl) phosphate does not contain chromophores that absorb at wavelengths >290 nm(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).

  • Uses: Emulsions of tris(2-chloroethyl) phosphate, blended with a binder such as a vinyl or acrylic emulsion, can be used for applications such as the backcoating of upholstery. It can be used as a secondary plasticizer in polyvinyl chloride to suppress the flammability resulting from plasticizers such as phthalates. Where a particularly high degree of flame retardancy is required, it can be used in combination with the aromatic phosphate plasticizers. Such formulations can serve as an alternative to the use of antimony oxide in plasticized vinyl polymers. Source: Hazardous Substances Data Bank (HSDB)

How CAS 115-96-8 is used on this site

CAS 115-96-8 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 115-96-8 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 115-96-8 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.
