Silicones on the spot – again
The Regulation (EU) 2018/35 establishes that Cyclopentasiloxane (D5) and Cyclotetrasiloxane (D4) are allowed only in wash-off cosmetic products up to 0,1% as of 31 January 2020.
In practical terms, this means that all wash-off cosmetic products will have to contain less than 0,1% of Cyclopentasiloxane (D5) or Cyclotetrasiloxane (D4) to legally enter the EU market from this date forward.
Wash-off or rinse-off cosmetic products are those meant to be removed with water after application. They include shampoos, hair conditioners, shower gels, liquid soaps, etc.
The European Chemicals Agency (ECHA) plans to extend the restriction to leave on products – those intended to remain on the skin, like creams and make-up products.
In March 2018 the German authorities launched a proposal for Cyclopentasiloxane (D5) and Cyclotetrasiloxane (D4) to be identified as Substances of Very High Concern (SVHC). If this proposal is accepted, further changes might come up as soon as the end April this year.
What is the problem with these ingredients?
Cyclotetrasiloxane (D4) is toxic to human reproduction and accumulates in the environment with unpredictable long-term effects. Cyclopentasiloxane (D5) can also be harmful to the environment. Both are biopersistent and bioaccumulative particularly in water environments.
The major issue is the silicones’ purity – or the lack of it. Cyclotetrasiloxane (D4) is a common impurity of Cyclopentasiloxane (D5) and vice-versa. Both are always linked.
What do you need to do?
- Reformulate all your wash-off cosmetic products to contain less than 0,1% of Cyclopentasiloxane (D5) and/or Cyclotetrasiloxane (D4)
- As a precautionary measure – plan to replace Cyclopentasiloxane and/or Cyclotetrasiloxane by other silicones in leave-on cosmetic products
In the EU, cosmetic ingredients are constantly under review by the Scientific Committee for Consumer Safety (SCCS) and Competent Authorities. The aim is to assess their safety and establish restrictions for the protection of human health.
Silicones are currently on the spot. The attention is drawn into one of the most widely used – Cyclopentasiloxane. Cosmetics manufacturers and their Responsible Person should closely follow the updates from the SCCS and the amendments to the relevant Regulations to make the right decisions towards ensuring compliance of their products on the EU market.
