Restrictions (personal care and consumer and professional products)
Following a scientific assessment of the substances for possible PBT and vPvB properties by the United Kingdom, a restriction on the use of D4 and D5 was adopted under the European Union’s Chemicals management program (REACH) in May 2017.
The scope of the restriction is limited to wash-off cosmetic products with a D4 or D5 concentration equal to or greater than 0.1% by weight of either substance. All actors that place on the market products that are within the restriction scope must comply with the requirements set forth in this restriction by January 31, 2020.
In response to this restriction, the silicones industry set up a large-scale Wastwater Treatment Plant (WWTP) monitoring program to help assess the effectiveness this restriction in reducing D4 and D5 down-the-drain emissions. Preliminary monitoring results indicate that D4 and D5 wastewater treatment plant influent concentrations are well below the baseline levels predicted, and in the case of D4, already consistent with the predicted post-restriction concentrations.
In April 2017, the European Chemicals Agency (ECHA) published its intention to assess the need for further restriction of D4 and D5 in leave-on personal care products and other consumer/professional uses (e.g. dry cleaning, waxes and polishes, washing and cleaning products).
In January 2018, the Commission requested adding D6 to the scope of this restriction, and to the scope of the ‘wash-off’ restriction. The restriction proposal on D4, D5, and D6 in leave-on products, as well as the addition of D6 to the ‘wash-off’ restriction was published in March 2019. The public consultation for this proposed restriction ends on September 20, 2019.
