Four New Products added to SVHC list

In the latest update to the list of substances of very high concern (SVHC), a further 4 substances were added in June 2014, mostly as a result of their “equivalent level of concern”.

 

1, 2-Benzenedicarboxylic acid, is also known as Diisohexyl phthalate (DIHP). Studies have shown selected phthalates in the category demonstrate significant effects on male reproductive organs and developmental effects, and that these effects are intrinsic properties of the reference phthalates and that DIHP, with C5-6 side chains should be similarly classified as Repr. 1B.

 

Less than 2000 tons of DIHP is used in Europe (NTP-CERHR, 2003). DIHP is used as lubricant in steering fluid and as plasticizers. In Australia, DIHP is imported for use in auto transmission lubricants (NICNAS, 2008c). Non-confidential commercial and consumer uses include rubber and plastics products and others (U.S. EPA, 2010). It is a commonly occurring plasticiser in PVC.

 

DIHP joins the chemically similar DnHP on the growing SVHC list of phthalates.

 

Two boron containing compounds (sodium perborate and sodium peroxometaborate) have been added, the chemical difference between the two compounds being their hydration state. Sodium Perborate is used extensively in a wide range of household products for its stains removing properties. The inclusion of these two boron compounds on the SVHC list provides harmonisation in the classification of boron containing substances as Repr 1B toxins.

 

Sodium perborate is sometimes used in leather processing as a replacement for hydrogen peroxide; it can be effectively substituted by sodium percarbonate as an oxygen donor.

 

Cadmium chloride is used in electroplating, in photovoltaic cells and as a chemical reagent. Its harmonised classification as a serious health hazard highlights prolonged exposure and the risk this poses to the kidneys and bones in particular.
