Science
Mechanism of Action
This ingredient operates by forming a protective, breathable barrier on the skin's surface, effectively minimizing transepidermal water loss from the stratum corneum and shielding against external irritants. Concurrently, its unique structure facilitates the deeper penetration of panthenol, leveraging its natural hydrating and soothing properties, while the silicone component imparts a distinct softness, silkiness, and cushioned texture to the skin.

Formulation
Stability
This ingredient is typically supplied as a 50% solution in water. It exhibits excellent stability within a functional pH range of 5.5 to 8.5, attributed to its unique composition that features both water-soluble and silicone-soluble groups.
Safety
Safety Profile
The CIR Expert Panel deems this ingredient, as part of the dimethicone polymer group, safe for cosmetic use when formulated to be non-irritating. However, safety data for incidental inhalation, such as from airbrush applications, remains insufficient. The US FDA recognizes it as a skin protector with a good safety profile at low concentrations. While EWG reports low concerns for common toxicities, the European Union Ecolabel program flags it as persistent, non-anaerobically degradable, and potentially detrimental to fertility.
