Cyclosiloxanes
Basic members of the broad family of silicone materials, all cyclotetrasiloxane (D4), cyclopentasiloxane (D5), cyclohexasiloxane (D6) are volatile oils with a cyclic chemical structure and various properties. They are widely used because of the smooth and refreshing feeling they create.
Origin
They are chemically synthesized from silica stones.
Consumer concerns and what we know
D4, D5 and D6 are persistent in the environment, although their long term effects are not known. D4 and D5 are not permitted in rinse-off cosmetic products in a concentration equal to or greater than 0.1% in the EU. D6 is currently being reviewed.
D4 has been listed as a potential reproductive toxic substance in Europe.
Our stance
We do not use cyclosiloxanes in rinse-off products such as shampoos and conditioners in response to environmental concerns.
We have stopped using D4 since it is suspected of having reproductive toxic effects.
We use D5 and D6 for leave-on products, carefully following EU regulations and updates.
