Science
Mechanism of Action
Forms a flexible, occlusive film on the skin surface that significantly reduces trans-epidermal water loss (TEWL) while maintaining breathability. The polymer's high molecular weight prevents penetration into skin layers, instead creating a protective barrier that locks in moisture and provides long-lasting hydration benefits.

Clinical Evidence
Medium confidence2%
Key findings
- 01 Copolymer-based complex delivered three times greater hydration improvement versus 2% glycerin, with severely dry skin showing 133% hydration increase and moderately dry skin improving by 35%
Transparency
Dusting Analysis
Not typically subject to dusting practices due to its functional role as a texture modifier and film former rather than an active ingredient
The Formula
Formulation
Stability
Exceptionally stable across wide temperature and pH ranges due to inert hydrocarbon structure lacking ionizable groups
Synergies
- Emollients
- Occlusive agents
- Water-resistant formulation components
Conflicts
- Strong oxidizing agents
Safety
Safety Profile
Reviewed under Polyene Group in 2015 CIR assessment. HRIPT testing confirmed no dermal irritation or sensitization potential. Maximum concentrations apply to color cosmetics; skincare typically uses 1-5%.
