Cyclomethicone ●
TL;DR. This ingredient is a volatile carrier and sensory modifier that helps formulas spread smoothly, reduces greasiness, and then evaporates to leave a dry, silky finish.
What does Cyclomethicone do in a cosmetic formula?
This ingredient is a volatile carrier and sensory modifier that helps formulas spread smoothly, reduces greasiness, and then evaporates to leave a dry, silky finish.
Is Cyclomethicone clean?
This ingredient has significant clean-standard friction because many frameworks restrict volatile organosilicon materials over persistence and bioaccumulation concerns. Skin irritation potential is generally low, so the main issue is environmental and regulatory standing rather than sensitization.
Is Cyclomethicone sustainable?
This material is synthetically made from mineral-derived silicon chemistry plus carbon-based methyl groups, with energy-intensive processing. It is not readily biodegradable and can persist in air, water, and sediment compartments.
Is Cyclomethicone COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. From a Green Chemistry view, it scores poorly on renewability and end-of-life because it is synthetic, volatile, and persistent rather than readily biodegradable.
How does Cyclomethicone work chemically?
The molecule is a small ring-shaped organosilicon compound with alternating silicon and oxygen atoms and methyl side groups, which gives high slip and rapid evaporation. It is typically used at about 1% to 50% depending on format, is broadly pH-stable in finished anhydrous or emulsion systems, and is not prone to oxidation under normal cosmetic storage.
