Description:
DOTP can be used in all of the flexible PVC products include toys, upholstery, fabrics as a non-
Phthalate plasticizer. DOTP is a nearly colourless, clear and practically anhydrous oily liquid. It is soluble
in the usual organic solvents like acetone, toluene. DOTP is almost insoluble in water. DOTP is miscible
and compatible with all of the monomeric plasticizers commonly used in PVC. So it can use PVC
formulation mixed with the monomeric plasticizers.
Storage
DOTP has an almost unlimited shelf life when properly stored in closed containers at temperatures
below 40 °C and the exclusion of humidity. Always refer to the Material Safety Data Sheet (MSDS) for
