Science
Mechanism of Action
It functions by creating a breathable, non-occlusive film over the stratum corneum, which effectively reduces trans-epidermal water loss (TEWL) while maintaining skin respiration. Additionally, it serves as a co-solubilizer that improves the dispersion of pigments and UV filters, neutralizing the inherent stickiness of complex formulations.

Key findings
- 01 Comparative emulsion testing at 0.4% inclusion demonstrated a statistically significant reduction in formula tackiness and improved sensory profile compared to Phenyl Trimethicone.
- 02 A primary dermal irritation study following OECD TG 404 guidelines using 100% concentration resulted in a Draize score of 0, confirming a non-irritating profile even at maximum exposure.
Transparency
Dusting Analysis
Because sensory improvements are measurable at concentrations as low as 0.4%, this ingredient is rarely used for 'label claim' only; however, formulations using less than 0.4% may not fully realize its texture-modifying benefits.
The Formula
Formulation
Stability
Highly stable across a wide thermal and chemical spectrum; resistant to oxidation and remains chemically inert when combined with natural plant oils or other synthetic siloxanes.
Synergies
- UV Filters
- Mineral Pigments
- Natural Plant Oils
- Dimethicone
Safety
Safety Profile
Safety profile is dependent on high-purity sourcing, ensuring that cyclic siloxane impurities (D4 and D5) remain below 0.01% in the final product.
