Emerald Kalama Chemical Completes Pre-Registration Process for K-Flex Plasticizers (7/7/09)
The dibenzoate chemistry, the basis for the K-Flex product line, has been identified by the European Chemicals Agency (ECHA) as a safer, viable alternative to various phthalate plasticizers that have been identified as “substances of very high concern” (SVHC).
Phthalate plasticizers classified as SVHC include benzyl butyl phthalate (BBP), bis(2-ethylhexyl) phthalate (DEHP) and dibutyl phthalate (DBP). These chemistries have come under increased scrutiny under article 58.3(c) of the REACH regulation because of their proven persistent, bioaccumulative and toxic nature (PVB) or very persistent and very bioaccumulative nature (vPvB), coupled with wide dispersive uses or high volumes. Of particular concern is benzyl butyl phthalate, which was targeted in the January 2009 ECHA report as an SVHC material with the potential to cause reproductive risks. This same report named dibenzoate plasticizers as an acceptable alternative to BBP, partially due to their ease of biodegradability.
