PERFLUORONONYLETHYL CARBOXYDECYL HEXACOSYL DIMETHICONE.

Avoid / SKIN CONDITIONING

PERFLUORONONYLETHYL CARBOXYDECYL HEXACOSYL DIMETHICONE is an organosilicon polymer intended to function as a skin conditioning agent, providing emollience, barrier support, and improved product spreadability. However, its 'Perfluorononylethyl' moiety strongly suggests it belongs to the PFAS class of chemicals, raising significant environmental and regulatory concerns.

Science

Mechanism of Action

As an alkylated dimethicone, this compound functions primarily as a skin conditioning agent. It is designed to impart a smooth, emollient feel, contribute to the skin's protective barrier, and enhance the uniform distribution and sensory experience of cosmetic formulations.

Safety

Safety Profile

CIR Status
Unknown
Sensitization risk Unknown

Direct safety assessments by bodies such as CIR or SCCS are unavailable for PERFLUORONONYLETHYL CARBOXYDECYL HEXACOSYL DIMETHICONE. Critically, the presence of the 'Perfluorononylethyl' component indicates it is a per- and polyfluoroalkyl substance (PFAS). A chemically similar compound, PERFLUORONONYLETHYL CARBOXYDECYL PEG-10 DIMETHICONE, is explicitly forbidden in European cosmetics due to its classification as a Persistent Organic Pollutant (POP) and a persistent, bioaccumulative, and toxic (PBT/vPvB) substance under the Stockholm Convention and REACH regulation. This raises serious concerns regarding its environmental persistence, bioaccumulation potential, and unknown long-term human health impacts, overshadowing typical dimethicone safety considerations.
