Science
Mechanism of Action
This high-molecular-weight copolymer (>500,000 Da) resides on the stratum corneum, creating a breathable, moisture-retentive film. By forming this lubricating barrier, it significantly reduces transepidermal water loss (TEWL) and facilitates the gradual release of humectants into the upper skin layers.
Research
Clinical Evidence
High confidence0.5%
Key findings
- 01 Clinical maximization assays confirm that concentrations up to 7.7% demonstrate zero sensitization or allergic potential.
- 02 Human Repeated Insult Patch Testing (HRIPT) at 0.5% concentration verified the ingredient as non-irritating and safe for sensitive skin applications.
Transparency
Dusting Analysis
While often used at low levels (0.2%) for texture enhancement, clinical safety and efficacy for moisture retention are well-documented even at these concentrations. It is rarely 'dusted' as it serves a functional rheological purpose.
The Formula
Formulation
Stability
Maintains high viscosity (~100,000 cps) in standard aqueous environments; however, thickness may decrease if exposed to high electrolyte levels.
Synergies
- Hyaluronic Acid
- Panthenol
- Water-soluble antioxidants
Conflicts
- High salt/electrolyte concentrations
- Strong oxidizing agents
- Highly alkaline environments
Safety
Safety Profile
The 2022 CIR Final Report confirms safety in current cosmetic practices. Its large molecular size prevents systemic absorption, making it a safe choice for all users.
