Tricresyl Phosphate (TCP)
CAS No.1330-78-5

Molecular formula: C21H21O4P
Relative molecular mass: 368.36
Structural formula:
1. Performance and use:
Tricresyl phosphate is an isomeric mixture of phosphoric acid esters of cresols. It is an odourless and colourless oily liquid (molar mass 368.4 g/mol, melting point –33°C).Tricresyl phosphates were used as flame retardants and plasticisers in PVC, nitrocellulose and acrylates.
Tricresyl phosphate (TCP) is used as a solvent for nitrocellulose esters and numerous natural resins.
It is a plasticizer for chlorinated rubber, vinyl plastics, polystyrene and polyacrylic and polymethacrylic esters. Tricresyl phosphate also acts as a binder for resins and nitrocellulose to improve toughness, elasticity and polishing properties of coatings.
Alone or associated with hydrocarbons, it is used as an antiwear and antifriction additive in numerous synthetic lubricants, incorrectly termed “oils” by reason of their appearance.
It is also employed as a hydraulic fluid. When incorporated in gasoline, tricresyl phosphate counteracts the harmful effects of lead deposits.
In addition, it is an excellent fire retardant in many industries.
Usually used as a mediator in the preparation of uranium-sensitive electrode based on membrane containing uranium di-(4-octylphenyl)phosphate as sensor.
Tricresyl Phosphate is used as plasticizer in vinyl plastics manufacture, as flame-retardant, solvent for nitrocellulose, in cellulosic molding compositions, as additive to extreme pressure lubricants, as a nonflammable fluid in hydraulic systems, as lead scavenger in gasoline
Tricresyl phosphate is used as plasticizer in vinyl plastics manufacturing; in spectacle frames; flame-retardant; solvent for nitrocellulose; in cellulose-molding compositions; additive to extreme-pressure lubricants; nonflammable fluid in hydraulic systems; lead scavenger in gasoline; used to sterilize certain surgical instruments; in polystyrene; in waterproofing; in common organic solvents and thinners; in linseed oil; emulsifying agent in cosmetics; in china wood oil; in castor oil.

3. Packaging and storage
TCP liquid is packaged in plastic barrels, 30kg or 250kg per barrel, which can also be determined according to user needs.
Store in a cool and ventilated place indoors, avoid moisture and exposure, and the storage period is twelve months.
4. Safety protection
Moderately toxic by ingestion and skin contact. Human systemic effects by ingestion: flaccid paralysis without anesthesia, motor activity changes, and muscle weakness. An experimental teratogen. Experimental reproductive effects. An eye and skin irritant. Combustible. When heated to decomposition it emits toxic fumes of POx.
