What is Tdcpp stand for?

Abstract. Tris(1,3-dichloro-2-propyl)phosphate (TDCPP) is a halogen-containing organophosphorus chemical that is widely employed in various consumer products with a high production volume.

What is TCPP flame retardant?

TCPP (tris (1-chloro-2-propyl) phosphate) is a flame retardant commonly used in polyurethane foam in consumer products and in home insulation, and in electronics. It is used as an additive to polyurethane foam and is not chemically bound, and it escapes from products into the indoor environment.

How do I get TCPP?

TCPP can be manufactured by either a batch or continuous process. TCPP is the reaction of phosphorous oxytrichloride with propylene oxide in the presence of a catalyst. The reaction is carried out in a closed reactor.

What is chlorinated tris?

Chlorinated tris is a chemical flame retardant. Adding flame retardants to products is one way to reduce flammability. Chlorinated tris can be gradually released from treated products into indoor environments, including houses, schools, day care centers, offices, and cars.

What chemicals make up chlorinated Tris?

Chlorinated Tris, or Tris (1,3-dichloro-2-propyl) phosphate is a chlorinated phosphate ester (#1). It is a colorless, viscous liquid at temperatures greater than 27 degrees C (#4). Chlorinated Tris in an additive flame retardant, meaning that is not chemically bound to products and can escape over time.

Do all tents have Prop 65 warning?

The REI website includes Proposition 65 warnings on all of Kelty’s tents, tarps and sleeping bags, but without stating the specific chemicals at issue.

Is TCEP toxic?

TCEP is toxic flame retardant added to polyurethane foam and is found in furniture and baby products, as well as some plastics and carpet backing.

What is flame retardant?

Flame retardants are chemicals that are applied to materials to prevent the start or slow the growth of fire. They have been used in many consumer and industrial products since the 1970s, to decrease the ability of materials to ignite. Flame retardants are often added or applied to the following products.

What is PBDE chemical?

Polybrominated diphenyl ethers or PBDEs, are a class of organobromine compounds that are used as flame retardants. PBDEs are classified according to the average number of bromine atoms in the molecule.

Does Tris contain phosphate?

Tris(1,3-dichloroisopropyl)phosphate (TDCPP) is a chlorinated organophosphate. Organophosphate chemicals have a wide variety of applications and are used as flame retardants, pesticides, plasticizers, and nerve gases….Tris(1,3-dichloro-2-propyl)phosphate.

Is fire retardant bad for the environment?

We do know that sprayed fire retardants feed harmful algal blooms along waterways and are toxic to fish. It demonstrates the potential for exposure to fire retardants to create ripple effects in the environment and wildlife far from where they are first used.

What are TCEP, TCPP and TDCP used for?

TCEP, TCPP and TDCP belong to the family of organophosphate flame retardants (OPFRs). TCPP and TDCP are used amongst others as flame retardants in flexible PUR foams in articles such as baby mattresses, car safety seats, baby slings, and residential

How does TDCPP work as a flame retardant?

TDCPP is a chlorinated analog of tris (2,3-dibromopropyl)phosphate (Tris) which is one of the most detected organophosphorus flame retardants (OPFRs) in the environment. Exposure to TDCPP does not significantly affect cell viability until at concentration >68 μg/mL.

How can TDCPP be removed from the environment?

TDCPP degrades slowly in the environment and is not readily removed by waste water treatment processes. TDCPP has been detected in indoor dust, although concentrations vary widely.

How does TDCPP affect the viability of a cell?

Exposure to TDCPP does not significantly affect cell viability until at concentration >68 μg/mL. HCECs show a 16% cell viability loss after exposing to 136 μg/mL TDCPP. Moreover, TDCPP induces a sharp decrease in viable cells (87%) after exposing to ≥272 μg/mL TDCPP.
