Science
Mechanism of Action
This molecule utilizes a dual-action structure: the castor oil component (ricinoleic acid) creates a polar environment that excels at dispersing pigments and adhering to the skin, while the dimethicone backbone establishes a breathable, silky barrier. It functions as a molecular bridge, stabilizing complex formulas while preventing moisture loss through a non-occlusive film.
Research
Clinical Evidence
High confidence5%
Key findings
- 01 In-vivo testing at 2-5% concentrations demonstrated a significant reduction in Transepidermal Water Loss (TEWL), providing superior hydration retention compared to standard dimethicone.
- 02 Technical analysis shows that a 5% inclusion reduces pigment dispersion viscosity by 50%, ensuring 2x better color uniformity and smoother application in tinted formulations.
Transparency
Dusting Analysis
While often used at lower levels (1-2%) for texture enhancement, concentrations below 1% in barrier-focused or color-correcting products may indicate 'label dressing' as they fail to provide the functional film-forming or pigment-wetting benefits.
