Cyclohexasiloxane
Low RiskA volatile cyclic silicone also known as D6, used for slip and quick-drying texture. Normal topical exposure is expected to be limited, but exact-ingredient pregnancy evidence is limited and cyclic siloxanes have route-specific toxicology and regulatory considerations. MamaSkin therefore classifies it as low risk rather than a pregnancy contraindication.
