Health Fate & Exposure Data

Years of studies have confirmed the safety of cyclosiloxanes for human health.

Some earlier studies indicated potential health effects from octamethylcyclotetrasiloxane (D4), but a series of new assessments in Toxicology Letters, and recent weight-of-evidence studies, add further compelling evidence that D4 does not present a risk to human health.

These recent assessments are consistent with a large body of peer reviewed publications supporting the safety of D4 and independent government assessments in Australia and Canada concluding that the use of D4 does not pose a danger to human health.
