Phthalate Di-isodecyl & Di-isononyl phthalates

2. How are DIDP and DINP used?

The source document for this Digest states:

DIDP

GENERAL INFORMATION ON EXPOSURE

There are currently four producers of DIDP in the EU. The estimated consumption volume in 1994 is ca. 200,000 t/a. An increase of the consumption of DIDP is to be expected over the following years. Approximately 95% of DIDP are used in PVC as a plasticizer. The remaining 5% are used in non-PVC applications. More than half of the DIDP used in non-PVC applications involves polymer-related uses (e.g. rubbers). The remaining DIDP is used in non- polymer applications including anti-corrosion paints, anti-fouling paints, sealing compounds and textile inks.

For the estimation of the releases to the environment through articles containing DIDP, the amount of substance included in articles being used outdoors or indoors, as well as the service life (technical lifetime) of the respective articles was estimated, as shown in Table 2.1.

DINP

GENERAL INFORMATION ON EXPOSURE

There are currently four producers of DINP in the EU. The estimated consumption volume in 1994 is ca. 107,200 t/a. An increase of the consumption of DINP is to be expected over the following years. Approximately 95% of DINP are used in PVC as a plasticizer. The remaining 5% are used in non-PVC applications. More than half of the DINP used in non-PVC applications involves polymer-related uses (e.g. rubbers). The remaining DINP is used in non- polymer applications including inks, adhesives and sealants, paints and lacquers.

For the estimation of the releases to the environment through articles containing DINP, the amount of substance included in articles being used outdoors or indoors, as well as the service life of the respective articles was estimated, as shown in Table 2.1.
